Harrison Potter was furious.

"NATSU" he shouted when he just set foot in the guild, he walked with sure steps towards Natsu who paled and began to flee.

But, unfortunately for Natsu, an astral hand stopped the 16-year-old's escape.

"How dare you steal my groceries... Do you know how hard it is to get my groceries?" said Harry furiously. He queued for 48 hours to get groceries that were said to be ingredients from heaven that had unfortunately been stolen by Natsu, unmistakably, the pink-haired teenager had eaten up his groceries.

"Dude... Your brother is really too much for groceries," Ron said rolling his eyes.

"Excuse me... Try the delicious ingredients you lost and see if you don't lose your mind," Charlie said defending his brother.

"Indeed, Harry had a legitimate reason to be angry," Hermione said.

"I wonder what kind of groceries require queues of up to two days," Padma said hesitantly. Even so, she began to wonder if in this world there are also rare ingredients that make people willing to queue for two days? She then shrugged her shoulders, not that she cared considering she didn't like cooking.

"If that's the case, it seems that the price is also very expensive," Michael said grimacing. Although Michael grimaced at the thought that there are people who are willing to queue for two days and pay dearly for the ingredients. Aren't ordinary cooking ingredients good enough? What's the point of wasting money to get rare foodstuffs?

"Err.. No," Natsu said haltingly at the anger of one of the S-class wizards.

"It took me two days to queue to get those groceries, not just waiting in line, the journey to the place to sell those groceries was also long and difficult, The price I spent was not small, I spent 12 million Jewels on those groceries you stole, you * thing" Harry said furiously.

"O oh, It looks like Natsu did it this time" Macao said to Wakaba who chuckled at Natsu's fear of Harry.

Natsu paled at the amount of Harry's groceries.

"Damn... You're really annoying Natsu" Harry said calming down, he didn't want to let go here and killed Natsu out of anger. He leaves Natsu frozen, watching the S-class wizard leave.

"Grandpa... I'm going to Crocus for a month," Harry said to Makarov, who nodded.

Harry disappeared from the guild with his magic.

"12 MILLION?" the students shouted incredulously, even the rich pure-bloods couldn't believe what they heard.

"What kind of groceries cost as much as 12 million?" Dean asked incredulously.

"Dude, Natsu really angered your brother, Charlie" said Seamus looking at Harry's angry face.

"He's scarier than Snape," Neville tweeted, which was echoed by the students who were also afraid of Snape. Snape, who heard Neville's words, frowned, but he couldn't do anything with Regen Longbottom and DMLE's head here.

Crocus

The city of Crocus was the largest city in the kingdom of Fiore as well as the capital of the kingdom located in the western part of the Isghar Continent.

The reason Harry went to this city was not only because he distanced himself from Natsu to calm his anger, but also to take care of his business development.

Harry, who is 16 years old and will reach 17 in six months, knows what kind of business he will develop. The business he will develop is a potions business as well as a casino. However, unfortunately to open a casino, he must first be of age, but it doesn't matter, he must first buy land in the capital to build his business.

"Casino? Why did he make a place to gamble?" asked the people in charge, saying it was inappropriate for a teenager to go to a casino let alone make one.

"But the casino business is lucrative," Michael said, recalling how much casinos in L.A. earn.

"As far as I can remember, casinos make $ 20 million a year," Terry said, watching the economic news in the muggle world. He is interested in the economy, mostly because he is not rich, and you could even say that his family belongs to the lower class. That's why he wants to get a decent job in the wizarding world with a big salary, unfortunately that means he will not work in the Ministry of magic, he is not that stupid to not realize the blood discrimination in the wizarding world does not reach the government. He might work as a curse-breaker in Gringotts or some other high-paying job that doesn't discriminate against him because of his muggle-born status.

"Luck in the casino is indeed high, the temptation to get rich quickly is the reason why gambling is favored by the upper class," Amelia sighed. Even his Aurors love to gamble, and they are law enforcers in the Wizarding World. It's only natural that people gamble to get rich quick.

Not just a casino, Harry also intends to create an information guild where people can buy and sell information, of course he will be the leader of the guild. The Guild will become a hidden guild until not everyone knows the existence of the guild, there are times when information is more valuable than money, after all information is knowledge and knowledge is power. Of course, they can buy information from him for a certain price, depending on how much information they want or how difficult it is to get the information.

"The eldest Potter is right, knowledge is power, if he can control it, he will become a more terrible enemy than Voldemort," Amelia said.

Headmaster Beauxbaton and Durmstrang are not happy to hear this, it's hard enough that they witnessed the powers of the eldest Potter indirectly, don't say that they had to witness his powers directly at Hogwarts in the tri-wizard Tournament. Their second champion's chances of winning are practically dwindling to nothing.

"If that one Potter becomes a Hogwarts student and is sorted, then he will become a Slytherin," said Daphne, who is considered a true Slytherin. Snape makes a choking noise hearing a Potter enter Slytherin, people who know Snape's hatred for the Potters sneer at the look on the Hogwarts Potion Professor's face.

"Indeed... He thinks like a Slytherin" said Andromeda which made Sirius pale imagining his godson, his son, would be a slimy snake.

"Next," said the bank teller Harry came to.

This bank is Bank Fiore which has many branches everywhere, it's just that the Main Bank in this Kingdom is located in Crocus which is the capital.

"I want to check my finances," Harry said to the nodding teller.

"Mr. Potter, Please Follow Officer Shirley to your Account Manager Room" said the teller which Harry immediately did by following a woman with Shirley's name pin to her account manager's room.

Harry's Account Manager is a young man who looks no older than 25 years old. His name is Howard Stern. A Baron in the Kingdom of Fiore who fell into poverty due to extortion by the Countess Philox.

The veterans grimaced.

"Noble conflicts will indeed never end" Hermione sighed, even the nobles in the muggle world also conflicted with each other.

"Indeed, Ms. Granger, Deception is a common thing in the life of nobles, whether it is nobles in the muggle world or nobles in the wizarding world," Professor Vector said.

The discussion with Baron Stern did not last long, Harry discussed the development of his business, he also asked Baron Stern to invest his money into other businesses, as a result Harry managed to get ownership of the Sorcerer Magazine, which is a prestigious magazine in the wizarding world that is always filled with gossip news or other articles in the wizarding world.

Including photos modeled by handsome and beautiful wizards, whether it was wearing closed clothes or even almost completely exposed because of the swimsuits they used, even Harry had used swimsuits and his photos were plastered in the magazine which increased his popularity, of course photos of him wearing closed clothes also appeared in magazines, people began to dub him Oberon the Elf King after photos of him wearing clothes royal and crown.

The men and women in the hall flushed watching Harry's almost round body plastered in another wizarding world magazine.

"Basically, Sorcerer Magazine is no different from the Witch Weekly Magazine in this world," Lavender said blushingly, especially when she saw Harry's sweaty pose in the otherworldly magazine.

"Potter... Your brother stole all the women even when he wasn't here," Cormac said jealously, despite this, a blush still visible on his face looking at Harry's photo posted in the magazine.

"Dude... Your brother is completely overpowered... Is there anything he can't do?"Cedric asked incredulously. Where does all that talent come from?

The men in the room were uncomfortable with the looks of the women who seemed to say 'Why can't you be like that?'It's not their fault that the eldest Potter is that great.

"Oberon, huh? A nickname that suits him"

"That's my godson," Sirius said proudly.

Harry also asked Baron Stern to buy him a territory large enough to create a fiefdom.

Despite being in another world, Harry is still a Potter, he is a Lord Potter based on Magic, Blood and Wills. The Potter family is the Most Ancient, Most Noble, Most Holy, and Most Honorable Family. To put it simply, the Potter Family is a noble family, Harry intends to make the Potter Family a Noble Family also in this world.

There are several conditions for becoming a nobleman in the Kingdom of Fiore depending on the rank of nobleman.

There are several noble titles, namely Duke, Marquess, Count, Viscount, Baron, Knight.

Harry is a knight, as he has no fiefdom, but he is clearly a nobleman thanks to his services and wealth. Harry's target is to upgrade the Potter Family to Duke. To attain the position of Duke, a family must have a fiefdom of at least 10 km, a fortune of at least 100 million Jewels, and a contribution of 100 contributions.

Harry himself has a fortune of 987 million Jewels thanks to the missions he does or his business, the contributions Harry has collected since becoming a wizard in the Kingdom of Fiore there are 80 contributions. Under normal circumstances, Harry would be promoted to Marquess who has a minimum fortune of 75 million Jewels with a contribution of 75 contributions, but because he has no territory, his status remains as a Knight.

"Potter is really ambitious," Blaise said, blinking his eyes many times.

"He's going to be a great Slytherin" Daphne said amusedly, even more amused to see people close to the Potters paled at the thought of Potter's Heir becoming a Slytherin.

"As if Harry is going to be a slimy snake like you," Ron said, staring intently at the Slytherin Ice Queen.

"It seems that the title of nobility in that world is no different from the title of nobility in the muggle world of this world" Hermione said, the muggle-borns who knew the noble rank nodded.

"So, the main requirement for promotion seems to be the most important is territory," Padma said.

"It's a natural thing, after all, nobles are the rulers of their territories and rulers will not be called rulers if they don't have territory controlled," Michael said.

"I will take care of the purchase of the land, Mr. Potter, It will probably take longer for the territory you hope to reach, but I am confident that I can buy your reserved land within a next year" said Baron Stern.

Harry has no problem with waiting, he's used to doing that. At least next year he will be 17 years old, the legal age of majority to own a business that is within legal and illegal limits and become a guardian for minors.

"It seems that the age of maturity in the magical world of that world is no different from the age of maturity of the magic world of this world," Madam Bones said.

"Although they can use magic as they please, they are without the restrictions of the statute of secrecy," said Roemmel Vance.

"I wonder why he wants to be a guardian for underage children?"

"To protect them..."Padma said that made people look at her confused.

Surprisingly, it wasn't Padma who explained, but Terry.

"Children are easy to manipulate, easy to shape, they are easy to trust, that's why people, especially dark wizards, often use children to perform actions for them," Terry said, which made the students, especially from the light side, disgusted.

"What's more, there are people who have thoughts of pain to torture, rape to kill children as their hobby... "From what we've seen so far, it's clear that Harrison Potter wanted to look after the children, especially when they came from the orphanage where he was raised," Anthony said, according to people familiar with Harry's actions.

Harry's goal in the near future is to bring his baby brother Charlus into this world, he knows that Charlus has a big problem because his magical core was damaged in Voldemort's attack a few years ago.

He of course knew his baby's plight, but he couldn't do anything, mostly because Potter Family Magic told him he had to be patient until he was old enough to go back and forth to his old world.

One of the Potter Family's magic is Relativity Magic, one aspect of relativity itself is Space. With the help of the Potter family's magic, it is not difficult for him to create a portal to go back and forth to and from his old world.

When his time came, he would take little Charlie into his arms, he would make sure those who hurt his baby brother paid dearly for their humiliation.

"I'm not a baby," Charlie said flushed from being called a baby by his older brother. Despite this, he felt warm, it turned out that his brother did not hate him and loved him, he increasingly wanted to meet his brother.

"It seems that he has a lot of affection for Charlie," Parvati said.

Ginny bit her lip, if Charlie was transferred to another world, she would not be able to become the wife of The-Boy-Who-Lived and get the fame she deserves. Ron and Molly are also not happy with this development, if Charlie the squib is transferred to another world, their chance to get the Potter family fortune after killing James and Lily Potter will be lost. Whatever happens, they must prevent the eldest Potter from taking The-Boy-Who-Lived to another world so they can gain control of the Potter family's fortune.

"But it's strange, if the Potter family's magic allowed Harry to return to this world when he was 17 years old, doesn't that mean that he has been able to come to this world since last September?" asked Hermione.

"Either something happened to him or something," Tracey said.

"Indeed, the eldest Potter is not seen as a person who broke his promise" Daphne said nodding at the hesitation of her friend.

The remarks of the two Slytherin students alarmed Charlie.

Harry, who had finished his business at the Bank, went to the Hotel to check in, the hotel where he stayed was Harris which came from Harry's name, Harrison, one of the lodging businesses owned by Harry.

All of Harry's businesses are indeed named Harris, besides being easy to pronounce, also easy to remember, every Harry business is under the Potter Family name which is marked with the Potter Family crest on every business owned by Harry.

The Potter Family Emblem is the Ten-Tailed Wolf who holds a golden sword in his right hand and a shield with a gold balance in the center of the shield in his left hand.

"So it's the crest of the Potter Family? Why don't you use your family crest, Charlie?" asked Hermione puzzled, which made Charlie scratch his head embarrassed, there was no way he would say that as a blood traitor, he was not allowed to use the name of the Potter Family, let alone use the family crest to his muggle-born friends who didn't understand the wizarding world, right?

Charlie just kept silent, he didn't know how to answer his friend's question.

"Isn't that obvious? The blood traitor has no right to use the family coat of arms, and you call yourself smart, are you an idiot, Granger?"it was Draco's sneer that made the Gryffindors look at him with displeasure, especially Hermione who was called an idiot by Malfoy, was he crazy? She was ranked first in their year, while Malfoy was only ranked 12th, on what basis gave Malfoy the right to call her an idiot?

Each tail symbolizes the principles of the Potter family, a Potter can be said to be a true Potter if he has these ten qualities, the traitors of the Potter family's blood are members of the Potter Family who violate one or more of these principles.

One of the Potter family's principles is not to be submissive and not weak. That is the reason why James, who is his father, only acts as the regent of Potter, not Lord Potter, because James Potter is subject to Dumbledore, because that is also why Charlie is not recognized as a Potter by the Potter Family's magic because he is weak.

But, Harry is different, he is a true Potter after 600 years The Potter Family produced blood traitors, he is the only one who can become Lord Potter and resurrect the Potter House to become the next Lord of the Potter Dome.

The Potters ducked in shame when they were stared at by people.

"Don't think only Potters are blood traitors in this room, if your family's magic has its own thoughts like the Potter family's magic, there are many people in this room who claim that pure blood will be thrown away by their family's magic" Arcturus Black said silencing all the laughter directed at the Potters.

Harry stayed for almost a month at the Harris hotel, this month, Harry's job was only to develop his business, he also monitored the state of the market, he also conducted interviews and pressed film contracts with film producers who came looking for him to be a star and model in the films they made.

The people in the room were just silent, they were no longer surprised by the eldest Potter.

Charlie is both proud and pessimistic about his brother, his brother has many talents, different from him, his brother is strong, he is weak, he feels that he does not deserve to be his brother's brother's brother.

"Hmmm"

Harry couldn't help but feel strange when he was near Mercurius, the Fiore Palace where the royal family lives.

He felt that there was a disturbance to time in the Palace, more precisely in the underground part of the palace, there was an artifact that could damage the flow of time. That's why Harry secretly sent a ghost, but the ghost disappeared, his magic was also sucked in as soon as the ghost approached the source of the time disturbance.

"It's not good at all," said Arcturus, who was loved by his sister Cassiopeia.

"What do you mean, Lord Black?" asked Augusta, she was one of those who did not recognize Sirius as Lord Black, she considered Sirius unsuitable to be Lord Black.

Arcturus simply ignored the woman, a woman who dared to question his grandson's integrity as the new Lord Black.

Unbeknownst to Augusta, she had angered the Most Ancient and Noble Black Family with her insolence.

"Time interruption? I wonder what Harry meant," Padma said.

"Possibility is like a Time Turner" said Daphne, who made the unspeakables pale, they should have guessed that the wizarding world in other worlds also had time turners.

"Yes... That would be a problem, I wonder how Potter copes with this," Theo said amused.

'Yes... I think there are some missions in the palace on the mission board, I think I'll take the mission in the palace and start my own investigation' Harry thought.

Time is one of the magic that belongs to the aspect of relativity which is the magic mastered by the Potter Family. The Potters ensure there is no threat to conceptuality, causality, relativity by overseeing all aspects related to the three magics, one of which is time magic.

Time magic is one of the dangerous magic to use carelessly, even Harry himself, who has mastered his family's magic including time magic, dare not mess with time, especially if it is related to time travel, the good future will be damaged if there are bad people who travel to the past. For this reason, the Potters are responsible for the supervision of all matters related to causality, conceptuality, and relativity including time.

Unfortunately, the Potters have produced blood traitors for hundreds of years until the responsibility was not carried out until Harry was born, even Harry could not do his duty because he was thrown into this world.

Those people who didn't know were shocked, they didn't expect the Potter Family's role in maintaining such a big balance.

"Wow.. Charlie, Your family is really amazing" Hermione said widening her eyes, she couldn't believe the role of her friend's family was so big.

"It seems that we have to wait for the young Potter to come here so that the supervision of all aspects of the three magics can run perfectly," said the Unspeakable Chief.

"Indeed, Mr. Potter has a more important role in this world than in that world," Senior Barty Crouch said.

"But do you think Harry wants to stay in this world considering Harry bought territory in another world?" asked Remus, rolling his eyes.

To people's surprise, they completely forgot that the eldest Potter bought the territory, so he would have stayed there instead of here.

After a month in Crocus, Harry returned to Magnolia. When he entered the guild after returning to his home, he was greeted by silence.

"What is it?"Harry asked the pale-faced Macao.

"Lisanna... Lisanna is dead, " Macao said, holding back the sobs that shocked Harry. Lisanna? Does that mean that's Lisanna? The sweet girl who calls him Harry-nii? Harry's heart was racing, but he had to think rationally.

"How?"asked Harry flatly.

"Elfman is losing control of his magic" said Macao inhaling his cigarette sadly which made Harry swallow violently.

He leaves the guild, no one stops him, because they know how close Harry is to Lisanna. Lisanna considers Harry who is a year older than her as an older brother, as well as Harry who considers Lisanna as a younger sister. He wanted to blame Elfman, but he knew that if there was no point in scolding Elfman, Elfman would also be destroyed for being the cause of Lisanna's death.

Zeus the cloud and Prometheus the sun reflect the emotions of their owner Harry. They flew over Magnolia furiously, a storm struck Magnolia, a thunderstorm they had never seen before.

"Strong power has strong side effects too" Amelia said. She mourns for the teenager who died in another world.

"Those who have the power must be prepared to be swallowed up by it," Arcturus said. He was one of those people who had great power and had to endure the effects of the great power he wielded.

"Potter is so powerful that he can cause such a storm," Blaise muttered as he saw Prometheus and Zeus flying through the sky and causing a storm.

"I'm scared"

"If Potter comes here, you will not have a chance to win," said Lavinia, looking amused at Fleur, who was reddened by the implication of Lavinia's words, calling her weak.

Harry returned to the guild in the afternoon after venting his anger and sadness on the hill behind Magnolia.

He is on another mission to get rid of the burden of his mind, he does not want to remember his memories with sweet little Lisanna.

The mission he performed was an S-Class mission.

"Is it wise to undertake a mission so soon when you have just arrived, Harry?"asked Makarov.

Harry just nodded at his grandfather's question.

"Do not sink into sadness and hatred, my son, it is natural to be sad and hate, but do not fall into the pit that will lead you to the pit of destruction... Unfortunately I have to refuse your request to carry out any mission with your mental state that is not good now" said Makarov with a stern look silencing all the protests that Harry would throw.

"Makarov was right... If Mr. Potter undertakes a mission when his mental state is not good, he will suffer deprivation instead of benefit" Rufus agreed with Makarov.

"I'm glad my godson has someone he can count on," said Sirius, though he was jealous of Makarov, who should have advised him, perhaps teaching him about women or men when the time came.

Harry sighed. He has to drink tonight to get rid of his negative thoughts.

"Harry better not get drunk," Lily said, glaring at her son, who was beginning to drink.

"He's a minor, How irresponsible," said Augusta Longbottom.

"He is under grief, I think it's okay for him to drink, after all, a year or a few months he will be old enough," said Cassiopeia Black amused to see her sister's grandson blushing with drunkenness.

What Harry didn't know was that he wasn't drunk enough to lose consciousness, let alone that he was at the age when his sex hormones were starting to activate.

James and Lily paled.

"Oh no," Lily said, clearly not interested in her son's sex life.

Charlie groans, he does not want to know his brother's sex life.

The Next Day

"What? Why don't we watch the sex?"demanding Lavender and Parvati, the people in the room also protested. Many were disappointed that they could not see Harry's naked body.

James, Lily and Charlie heaved a sigh of relief.

"A bunch of perverts" grumbled Arcturus Black.

Harry woke up with a severe headache. He felt his stomach heartburn, he felt nauseous. He blinked his eyes many times and looked around and was surprised. There were naked boy and girl beside him.

Harry blushed as the memory of last night came into his mind. He had taken off his virginity last night, moreover, the first person he had sex with was a boy and a girl.

'Ugh... thought Harry. He is not homophobic and he knows that Gray is a pretty boy, plus his body although including thin, but quite muscular.

The men and women giggled looking at the naked bodies of men and women on the screen.

"Oh no" Charlie grumbled seeing people focused on his brother's body.

"Harry shouldn't impregnate anyone," Lily said angrily.

"I'm going to have grandchildren" said James amused which made Lily glared at him which made him swallow violently.

Harry paled. He knows that if he is not Bottom because he does not feel pain in his ass, it means that he is Top. Even so, he still feels guilty, knowing that his magic will prevent him from being impregnated by someone else before the age of 17, but that doesn't mean he can't conceive someone else before the age of 17. For now, he will supervise first.

"Magic does prevent underage pregnancy.. But I don't know if the magic in the world is the same" Amelia Bones said.

These ignorant muggle-born are shocked.

"No wonder there have never been cases of underage pregnancy" says Michael Corner. Despite being a Ravenclaw, he had never found out about a wizards pregnancy before.

"With such good looks, Harry is fit to be a Top" lavender giggled which made Parvati giggle. They nosebleed at the thought of a naked Harry having sex with Gray who also had good looks, although his body was less muscular than Harry's.

"Lavender... I don't want to hear about my brother having sex," Charlie said. He must admit that his brother is handsome and sexy, but he is his brother, his real brother, he feels guilty to feel horny to see his brother's naked body. Would his brother hate him for being horny to see him?

The girl he has sex with is Mirajane Strauss, an S-Class wizard who lost her sister. He feels like trash now, it's as if he took a chance on Mirajane's suffering. Mira is a beautiful woman, yes, she is, but that doesn't mean she is sexually attracted to Mira. Even if there is a woman who he is sexually attracted to is a water wizard from The Phantom Lord named Juvia whom he met on a mission a few years ago.

The women in the room giggled at Harry's confession.

"So my son is in love?"asked Lily smiling.

"More like lustful" James said smiling silly.

Charlie felt reluctant, he was clearly not interested in hearing about his brother's love life.

Harry then takes Gray and Mira to their respective residences. Mira lives with Elfman and Lisanna, now she only lives alone with Elfman. While Gray lives in an apartment located not far from his apartment.

'Maybe I should buy a house,' thought Harry. He considered that if Gray and Mira were pregnant because of him, he would definitely need a house, not just an apartment. But he will refrain, the process of purchasing his territory will be completed next year, as well as the process of raising his peerage. For now, he will be patient.

"Smart... He doesn't need to rush because he has a peerage," Amelia said.

"Indeed, he just needs to wait while contributing to the kingdom so he doesn't have to waste money on unnecessary things," Augusta said.

Harry came to the guild the next day. Gray and Mira blushed and avoided him.

'Oh come on.. I'm drunk ' thought Harry. Nevertheless, He is happy that Mira has found other activities to fill her free time. Mira went from an Active s-class wizard to a bartender in the guild. It seems that the shock that Mira experienced shook her so hard.

"Harry... Please train me" said Natsu seriously which made Harry whistle, it had been a long time since he saw Natsu's serious face, it seemed that Lisanna's death also had an effect on Natsu, although in fact they were not very close.

"All right... I'll wait for you at the beach," said Harry walking to the beach behind the guild.

"Ha'i"

"Hmmm... It looks like he's determined to get stronger, good for him," Kingsley said.

"But he lacked constant vigilance" said Alastor Moody falsely.

"Most likely he never faced a strong opponent who really wanted to kill him" Amelia.

"Excuse me, aunt, isn't Harrison already very strong?"Susan asked her aunt.

"Mr. Potter is indeed very strong, but he clearly does not want to kill his friend... I hate to say this, but a person can develop under pressure, but since Mr. Potter is obviously holding back from not wanting to kill his friend accidentally, it kills Mr. Dragneel's development is hampered" Amelia said which made Susan nod understand, veterans also understand Amelia's intentions, there is a reason why they are stronger than the new generation, they are war veterans, a battlefield where they can die at any time because of powerful enemies who are not merciful.

Beach

"Natsu... As I told you before, you are so dependent on your magic that you neglect your physical aspects... Your body is muscular, yes, but your muscles are not well developed, in hand-to-hand combat, you can be defeated by Gray easily" said Harry which made Natsu frown, he did not want to be underestimated, especially when considered weaker than the glazed-eyed ice princess.

"This training includes physical training and magic training... I want you to at least do push-ups, sit-ups, pull-ups and squat-jumps 100 times a day so that your muscles develop properly... For Magic training, you are wasting your mana too much, your control is not good, that's why this magic training prioritizes magic control. You will train to lift the rocks on the beach with your magic just burning and destroying them" said Harry which made Natsu swallow harshly, but he still nodded. He doesn't want to be weak anymore.

The war veterans nodded at what the eldest Potter said.

"He's going to be a good teacher," Michael told the students.

"He's knows the shortcomings of others and shows the methods of solving them, he is more a teacher than some professors at Hogwarts" said Daphne who made the Hogwarts professors offended and stared at her.

"What? That's right, Snape only commands students, not educates, moreover he has a disgusting bias, Mcgonagal pretends to be strict but does not help at all other than urging students to achieve her targets, Binns need not be asked again, Sprout is too soft so that students play around in class, the only one who really deserves to be a teacher at Hogwarts is Professor Flitwick" said Daphne which made the teachers blush with shame and anger, Snape stared intently at the Greengrass heir for daring to protest his way of teaching.

Training for Natsu runs for more than six hours, three hours of which are made for Natsu's physical training, another three hours for Magic training.

Natsu may not be a book genius, but he is more of a practical genius. It absorbs knowledge faster by acting or practicing instead of reading and listening. As a result, Natsu managed to master the technique taught by Harry in three hours, although Harry was quite disappointed considering that the technique he taught was actually not too difficult, yes, the ability of people to absorb knowledge is different, he will be silent for now, he does not want to destroy Natsu's spirit in training.

"He is indeed fit to be a teacher" said Rufus Scrimgeour nodding which the Aurors considered.

"He knows the shortcomings of his students, but is not disappointed, but rather proud" said Dawlish.

"Good job, Natsu, you made it to the target" said Harry, he did not lie, although the progress was slow, but Natsu did make it to the target for today.

Natsu was panting, his shirtless body drenched in sweat. Although exhausted, he still had a smirk that indicated that he was happy with the praise from S-class wizards like Harry.

There were many blushing women and men watching Natsu's naked body on the screen.

"Is the eldest Potter Sane? How could such a body be said not to be perfectly developed?"Tracey asked drooling looking at Natsu's body.

Natsu is indeed handsome, especially when his hair is disheveled and his look is serious, losing his childish look.

Harry leaves Natsu so Happy to come pick Natsu up to take home. Harry also went home, he will choose a mission to do tomorrow morning.

"You're a mission freak.. Did he forget that he had just had a threesome?"asked Fred.

"Lucky bastard," said George.

They are easier to understand without their usual word connections.

"Fred... George... Watch your mouths" Molly shouted in her characteristic shrill voice that made many people close their ears in pain.

"He must be trying hard to make money for his future baby" said a giggling Parvati who was considered Lavender who also giggled.

Hermione rolled her eyes at the chatter of the two roommates. Can't they stop being childish for a moment? Is that a hard thing to ask?

The students and staff as well as the people who were in the Hall stretched their bodies, they moved to find a comfortable position for the next reading, the house elves went the extra mile of giving comfort to the people who were trapped inside the Great Hall of the more than thousand-year-old castle.
