"This chapter is going to be the last chapter of the day," Dumbledore decided, making the students, staff and other attendees complain that they wanted to know more about the other world.

It had been two months since Harry woke up naked after getting drunk and having sex with Gray and Mira, fortunately until now there were no signs of the two being pregnant which made Harry sigh with relief. While he wanted children and a family, having a child when he was 16 and even more so without the bonds of marriage was clearly not his plan.

The Potters breathed a sigh of relief. James and Lily would not be happy with the presence of a child out of wedlock, while Charlie did not want to be an uncle when he was only 13 years old at the time.

Of course there were those who felt disappointed by the lack of children from Harry's Threesome relationship two months earlier, but they held back their comments for now.

Some were happy, of course some were disappointed, they wanted to know what kind of child was born from a powerful and handsome wizard like Harry with other handsome and beautiful Wizards, plus Mirajane was definitely an S-class wizard which showed that she was clearly powerful like Harry.

Moreover, Harry felt dirty, he Of course knew that he had a marriage contract with Athena Laventainn from the most ancient, most noble and most honorable Laventainn family. This contract was made by his grandmother Dorea Potter nee Black who did not trust her son and his wife to take care of her grandson, in other wordsshe and Charlie. If he is contracted with the Laventainn family, then Charlie is contracted with the Greengrass family, both are absolute contracts, in other words, if the Laventainn family and the Greengrass family refuse, then the Potter family's Magic will claim the lives of the Laventainn family's daughter Athena, as well as the Greengrass family's daughter Daphne.

The Greengrass family who didn't know this was shocked.

"Wait... I have a marriage contract with Greengrass?"Charlie asked confused.

'That bitch' thought Ginny furious at the surprised Daphne Greengrass.

Slytherin is shocked to learn that The Ice Queen Slytherin is engaged to a Gryffindor, even more so to a Potter who almost squibs.

Astoria is surprised that her sister is engaged to Potter. Charlie Potter is not bad, but his magical talent is average, different from her sister who is included superior in the class.

"The marriage contract is Savage" said Hermione immediately which made the purebloods look at her with annoyance.

"Before you say something that makes people want to kill you, it's best to find out more about the wizarding world and ignore the Muggles' nonsense, Ms. Granger," Cassiopeia said, silencing Hermione.

Harry is currently in the guild.

Today is a day where everyone relaxes considering that the mission on the Lower Mission Board has been empty and will only be filled tomorrow, for some reason, everyone bought a mission a week to three days ago so that the mission on the Mission Board runs out.

To be honest Harry was surprised, usually most guild members would be lazy because they were not short of money. Harry himself also plans to be lazy, he doesn't really need money anymore considering he is rich enough.

"With the wealth we saw earlier? Yes, he really doesn't need wealth anymore" said Andromeda amused.

"Indeed... Although I think he still needs a contribution to become a Duke, is it good for him to be lazy when his target is that high?"asked Augusta who makes people roll their eyes.

"There's nothing wrong with relaxing after work, Augusta," said Professor McGonagal, who had been scolded by Regent Longbottom.

"TING TONG TING TONG... GILDARTS SHIFT IS ABOUT TO BEGIN... GILDARTS SHIFT IS ABOUT TO BEGIN"

An announcement was announced that shocked the residents of the city of Magnolia who were in activity. They quickly got out of the way and held on to what they could so as not to fall.

"Gildarts Shift?"asked a confused Lucy. As a newcomer, she had never met Gildarts before so she did not know what Gildarts shift was.

"Gildarts are destructive wizards, so if they're not careful what they do, they're going to get destroyed, which is why Grandpa asked that Magnolia be renovated," Harry explained to Lucy. Lucy listened and widened her eyes as she saw the building move into place, creating an open path that led directly to the guild.

"Impossible," said Lucy. She was surprised by this, what kind of madman would move a city for just one person to walk through and what kind of madman would destroy everything in its path with his magic by accident?

The students and adults in the hall were also shocked.

"That's crazy," people shouted in disbelief.

"It's more like stupidity," Professor Mcgonagal said.

"It seems that the destructive magic is so powerful that the city was renovated for only one person to pass through" Madam Bones said, secretly she was grateful that there was no one capable of using such magic in this world, for the sake of our name, especially on the dark side, otherwise the magicians in this world would have fallen into a panic.

"Master..."Gildarts laughed. Gildarts is an old brown-haired man. He was wearing a robe that covered his body.

"So, what about the mission?"tanya Makarov looked at one of her senior guild members.

"HAHAHA... I'm sorry, Master, I failed" said Gildarts. He then opened his cloak revealing his body covered in wounds.

"My left leg and right hand are destroyed, my internal organs are also damaged, I'm lucky to be alive" said Gildarts who surprised everyone because they knew that Gildarts was the Ace of Fairy Tail.

Gildarts returns to his home, and The Other Fairy Tail Wizards remain silent in honor of Ace Fairy Tail.

The veterans grimaced watching this, the fake Moody grimaced, he even felt the discomfort of imitating the real Moody, imagining what happened to the destruction wizard could happen to him, it was unbelievable.

"What kind of Mission does he do?"Susan was surprised.

"It seems like a more dangerous mission than Harry's," Michael said in surprise.

"What kind of mission did Gildarts-san carry out to such an extent?"asked Lucy curiously.

"100 years," Harry replied.

"A 100-year mission? Isn't the highest mission an S-Class mission?"asked Lucy doubtfully.

"No... The missions consist of D-class missions, C-Class missions, B-class missions, a-class missions and S-Class missions. The S-Class mission itself is divided into three missions, S-Class Mission, SS-class mission, SSS-class mission. Above the S-Class mission there is a 10-year mission where this mission has not been completed in ten years, above there is a 100-year mission where this mission has not been completed in a hundred years" explained Harry who surprised Lucy.

'An unresolved mission for a hundred years? What kind of mission is a 100-year mission?'thought Lucy.

"It's still too soon for you to take on a 100-year mission, Lucy," Erza said. He was confused by the look on Lucy's face.

"Do you think I want to take on such a mission?"Oh!" cried Lucy in surprise.

The people who heard Harry's explanation were confused and doubtful.

"What kind of mission is that?"Amelia asked surprised. As difficult as the 100-year mission was, Gildarts, the Ace of Fairy Tail, lost his limbs.

Despite the seriousness of the situation, the giggles of the Weasley twins slightly broke the seriousness of what was happening.

"Good misunderstanding" said Hermione slightly laughing.

In the evening, Harry was called by Makarov to his office.

"Harry, I want you to do this 100-year mission," Makarov said, surprising Harry.

"Really? Didn't the failed Gildarts just come back, do you think the mission giver will give Fairy Tail a chance to try again?"Harry hesitated.

"I know... But you have surpassed Gildarts a long time ago, this mission should have been yours last year, but since you had another mission at that time, this mission was given to Gildarts" Makarov said seriously which made Harry sigh.

"All right... I will carry out this mission," said Harry, whom Makarov considered satisfied.

"This mission comes from the Guiltina continent, more precisely in the Ancient Dragon Guild which is the first Guild in the world," said Makarov.

The black-haired teenager then went to his apartment to prepare the necessary items for the mission.

"WHAT DID THAT MADMAN THINK OF SENDING MY SON ON THAT MISSION?"Sirius Black is angry. His magical Aura flared up in the room which made people uncomfortable because the black family's magic thick with suffering hit them.

"Son?"ask the stammering people.

"I adopted Harry by blood and magic when he was born so he is my son by blood and magic," Sirius said, gritting his teeth at Makarov on the screen.

The Guiltina Continent

Guiltina continent was a strange continent, a continent thick with magic so Harry's magic was instantly full even though he used large-scale techniques. This continent is also known as the Green Continent because more than 70% of this continent is wilderness. Yes, only 30% of the continent is urban and Rural, even if there are cities and villages in the forest, their buildings must be made of wood.

The Ancient Dragon Guild itself was located on the edge of this continent.

"Hmmm... Interesting Guild" murmured Harry staring at the guild with a giant dragon statue before him.

He entered the guild and was greeted by a loud voice.

"Who are you to dare to enter this place?"asked the heavy voice that Harry saw was a bearded dragon.

"D...D...Dragon?"shouted the students, the veterans were also shocked by what they saw.

"Dragons can speak human language?"Blaise asked surprised.

"Or maybe he used parseltounge? Since we're basically looking at it from Potter's point of view, it's possible that we hear and witness what Potter sees and hears," Daphne said, trying to reason.

"Good idea, Daphne..."Tracey laughs.

The Wizards of light were disgusted at the thought of a Potter being a family of light as well as the family of the-Boy-Who-Lived being a parselmouth. The only light side that is not disgusted is Charlie W who is fascinated by dragons that can talk to humans even through parseltounge, Bill who knows that Parseltounge is not black magic, Charlie who is fascinated by his brother who can meet Dragons at close range.

"Hmmm... You're not a dragon, are you? Your soul tells me that you are a Dragon Slayer who turned into a dragon due to the side effects of Dragon Slaying Magic" said Harry seriously which made the giant dragon laugh.

"HAHAHAHA... A soul Wizard, huh? It's been a long time since I met a soul mage," said The Dragon, who then turned into a bearded man, complete with a pointed hat.

"My name is Elfseria, the founder of the Ancient Dragon Guild, before you ask, Yes, I am over a hundred years old, Dragons have long lives, as a Dragon Slayer who turns into a dragon, I also get those long lives" Elfseria said.

"I didn't ask and I'm not interested," said Harry flatly, sending Elfseria tumbling backwards.

"It is very rare for me to meet a person who is not interested in my longevity" says Elefseria.

"I am not interested in longevity or immortality, life is precious because it is only lived once and the time is limited so that people fight as much as possible to live today," said Harry who made the old man whistle.

'Such wisdom' thought Elfseria.

The war veterans were surprised by the wisdom Harry showed.

"Your brother is wise too," Dean said looking at Charlie in surprise.

'Life is precious because it is lived once and time is limited, huh? Charlie thought, a smile on his lips.

"All right... Let's start the mission contract... This mission is a mission where the potential for your death reaches 98%, that's why the contract is needed so that even if you manage to survive, you will not be able to give the details of the mission to others if the mission fails" said Elfseria who considered Harry, not that he would fail this mission.

Elfseria who saw Harry finished signing the contract immediately explained the 100-year mission.

"Your mission is to seal the five Dragon gods... There were five Dragon gods in Guiltina who each of them had the power to destroy civilization, they had slaughtered countless innocent humans. They are Selene the Moon Dragon, Ignia the Fire Dragon, Mercphobia the water dragon, Aldoron the Wood Dragon, and Viernes the Golden Dragon... Seal them, you can do anything to seal them" said Elfseria.

If Harry was surprised, he showed no surprise. He just nodded. Elfseria then explained the location where she could find the Dragon God, of course, Elfseria only knew the location of two of the five Dragon gods, but at least that was enough for Harry to act.

"Kill The Dragon? That's crazy."

Charlie and the other dragon tamers trembled in their seats.

"How dare they want to kill the Dragon" shouted Charlie angrily. Hagrid who was sitting beside the dragon tamers was also angry, his body trembling until their benches trembled along.

"If the Dragons have committed slaughter, of course they must be eliminated" said senior Bartemius Crouch flatly which made the dragon tamers stare intently at him which he ignored wholeheartedly.

The location of the Water Dragon God is not difficult to reach, in fact Mercphobia turned out to be the protector of a seaside village in the southern part of the Guiltina continent.

"Looks like you're after me" said a disheveled blue-haired man. Harry knew immediately that the man in front of him was Mercphobia, the water dragon god he was looking for.

"Hmmm... Interesting, I know that dragons can do transformation magic, but I'm surprised that you would choose a human form that dragons think is nothing more than dinner" said Harry flatly which made the woman beside Mercphobia angry.

"Hey... Watch what I say, the Water Dragon God is the protector of this village, your disrespect must be punished" the woman said but was stopped by Mercphobia when she felt anger from Harry because of her assistant's remarks.

"All right, all right, calm down... Come into my Castle," said Mercphobia, which Harry, knowing from the Dragon's soul, did not mean him any harm.

"He lacks constant vigilance" cried the fake Moody as soon as he saw Harry enter while lowering his guard.

"He knew from the Dragon's soul that it wouldn't hurt him, Alastor, he believed in magic," Amelia said.

"And tell me, Bones, are Dragon souls the same as human souls? What if the dragon could manipulate his soul to lie to the Potter boy?"asked the fake Moody who made those who knew him sigh at the sight of his paranoia.

"Dragons can do transformation magic?"asked Susan horrified. Many people were also horrified to hear this, the only ones who were not horrified were the dragon tamers as well as Hagrid who beamed at the thought of Dragons turning into humans, they thought they could talk to them if dragons used transformation magic. Talking to Dragons is a highly desirable ability of dragon tamers, they love dragons, they want to understand them.

"Truly terrible, those savage creatures must be exterminated immediately" said Umbridge squealing like a girl whose scream could match the legendary screech of matriarch Weasley.

"NO NO NO... Never hurt a dragon, bitch Toad" shouted Charlie who made the Weasleys gasp, Fred and George chuckled at their brother's screams.

"CHARLIE... Take care of your language" shouted matriarch Weasley angry at the colorful language of her second son.

"Welcome to my castle..."mercphobia laughs.

"Hmmm.. For a dragon, you are a connoisseur of art too, " said Harry was interested to see the sculptures and paintings in the underwater palace. After all, painting is one of Harry's hobbies.

"So you got a mission to kill me?"asked Mercphobia starting a conversation.

"More precisely sealing you, killing you is just one of the ways there is to seal you" said Harry.

The woman next to the Water Dragon God seemed to be about to speak again, but Mercphobia cut her off before she could speak.

"Do you think there is a way to seal me?"asked Mercphobia. Harry immediately knew that if the water dragon god before him was afraid of his own strength, it seemed that he would be easier to overcome.

"There is... One, I used my magic to change your name... Two, I pulled out your magical core that makes you no more dangerous than an ordinary human, but your magic will eventually be mine because the laws of magic will point out that I am the one who has defeated you" said Harry honestly.

"He can do that? Wait,what does it mean that the water dragon god's Magic will be his?"asked Hermione.

"Isn't that obvious, Granger? The law Harrison Potter meant was the law of Conquest" said Daphne surprised to see Granger didn't know this simple thing.

"As far as I am concerned it is the right of conquest when one defeats another in battle, not by permission as Harry did," said Hermione frowning.

"There are many theories about the right of conquest of Ms. Granger, and the time will not be enough if it has to be discussed here" said Madam Bones cut off the conversation between the two girls.

Mercphobia thought for a moment, the look on her face finally showing enlightenment.

"All right... I agree, my great power feels like it will be wasted if not used, please take my power and make it yours" said Mercphobia which surprised Harry, he thought the water dragon god before him would think that lowly humans seemed inappropriate to have his power considering Dragons are the top of the food chain and consider humans to be nothing more than their food.

"I was also surprised... That Dragon is definitely different from the Dragons in the storybooks I've read... Dragons are usually synonymous with pride and arrogance" says Tracey.

"I doubt it will be that easy," said Theo.

"Indeed... As people said, Karma is the bitch," Blaise said.

Of course, it won't be that easy. When Harry was about to begin the process of retrieving Mercphobia's magical core. Mercphobia suddenly let out smoke, her eyes flickering between white and red.

"AAAAAA" Mercphobia screamed in pain. Harry was surprised but did not freeze, he immediately pulled the woman next to Mercphobia away from the underwater castle.

Mercphobia transforms into her dragon form, a blue being that symbolizes the color of water. The changes affected the environment, the sea rose to the sky, the sea swirled above them.

Blaise's friends looked flatly at the dark-skinned teenager.

"You must be jinxed, right, Blaise?"asked Theo amused.

"It's not my fault," Blaise said defensively.

"It seems like the Dragons in the other world are stronger than the Dragons in this world" said Charlie W scratching his non-itchy head.

"Of course not, Sherlock," snorted Draco.

"Wait... How do you know Sherlock Holmes?"Charlie asked surprised to see Draco who used the Sherlock Holmes reference that made Draco blush.

"I don't need to answer your questions, Potter," Draco replied, trying to keep his face level.

Mercphobia gets out of control, it begins to attack the civilians it protects. Water gushed from the sea that rose into the sky causing damage.

"Yare yare... It seems like a fight is inevitable, " Harry said. It cuts off the water that sprays towards it.

"Dragon against Dragon... Sit on the frozen heaven, Hyourinmaru" said Harry. From his sword emerged an ice dragon that attacked Mercphobia. The term no place for two dragons in the sky was actually practiced by the two dragons in the sky, they began to fight each other.

"Hyourinmaru... Please face Mercphobia for a while until I finish evacuating the population" Harry said to the spirit of his strongest ice-type Zanpakutou.

"Leave him to me, My Lord" Hyourinmaru said with a grin. The ice dragon was fighting against the water dragon in the sky.

"That place looks like hell," Dean said.

"Hell? Is it not filled with fire and water?"Ron asked confused which made Hermione sigh.

"That's a phrase, Ron," said Hermione rolling her eyes that made Ron blush.

"I know," Ron whispered.

It turned out that the evacuation of residents was slow because they did not want to leave their masters. According to them, their masters need them.

"What exactly can weak people like you do? You guys are nothing more than pathetic insects that can't even fly on their own" said Harry sneering looking at the stubbornness of the inhabitants protected by Mercphobia.

The residents were outraged by what Harry said, but they could not retaliate because Harry had forcibly removed them.

"The wind blows from North to South, swirls from East to West, Kochi"

Kochi is the strongest wind-type zanpakutou. Kochi's ability is the wind that gives Harry the ability of Aerokinesis. Harry uses Aerokinesis to fly the villagers away from Mercphobia's reach.

"While his words are harsh, he is right, they will only hinder him" said Rufus Scrimgeour.

Charlie grimaced, he is one of those weaklings, does that mean his brother doesn't love him?

After he felt the inhabitants had gone far away, he immediately flew to the site of the battle between Mercphobia and Hyourinmaru.

The location of their battle had been filled with ice and water everywhere which showed as if an ice storm had just hit the place.

"Good job, Hyourinmaru" said Harry, he then eliminated Kochi.

"Bantai, Daiguren Hyourinmaru" whispered Harry.

Harry suddenly glows, when the Rays run out, he is seen to have wings and a tail made of ice. This is the second release from Hyourinmaru. Hyourinmaru had fused with his master who gave Harry the ability of Cyrokinesis.

"Hmmm... Interesting technique... It seems like master Potter's Zanpakutou gave her a variety of different abilities" Madam Bones said.

Dumbledore was envious of the strength shown by young Harry, such strength should be his, perhaps he should consider inter-dimensional travel after this, he believed the Phantasm magic owned by Harry learned in another dimension, he would become the strongest wizard in the world when it belonged to him. Dumbledore may be arrogant, but he is not stupid, the only reason why he is strong is because of The Elder Wand he has, he lacks knowledge, he naturally asks his followers to give him knowledge about their family's magic, but they do not want to tell him.

"Let's start our battle, Mercphobia, no, I mean, the Water Dragon God" said Harry. His magical Aura was scattered, the Water Dragon God was unmistakably much stronger than any ancient demon he had fought before, neither Ichimonji nor Minazuki would succeed against him, because ink and blood were liquids, and liquids themselves were capable of being manipulated by Mercphobia.

"RAAAAA"

Mercphobia roared furiously, the ocean in the sky bubbling spraying thousands of water frozen by Harry who was controlled to attack Mercphobia. But, Mercphobia got the nickname of the Water Dragon God not without reason, if Harry can freeze all liquids, then Mercphobia can melt all solid objects.

Thawing against freezing.

The fight between Harry and Mercphobia took twelve hours until Harry began to feel tired, but he refused to lose considering that Mercphobia also began to show fatigue.

"Dude... Is he really human? He could fight a dragon god like that... Maybe a dragon, but he is basically a god among Dragons" Dean said in a cold sweat.

Charlie stared admiringly at his brother's fight.

"He fought for twelve whole hours and just sweated a little? How strong is he really?"Cedric asked incredulously.

"His power is on another level," Susan said.

"One can thaw anything, the other can freeze anything... What a fight full of romance" said Lavender sighing.

"This reminds me of the romantic novel I read last night," Parvati sighed.

"You mean the novel titled Prince Of Ice and Princess Of Fire?"ask Sally Anne-Perks

"Yes"

"Good Novel, Parvati" Sally praised, as a muggle-born witch, as well as a female teenager at a legitimate hormonal age, she is no stranger to romance novels, moreover, the novel The Prince Of Ice and The Princess of Fire is a 19+ novel that is a best seller on the market. It slightly surprised Parvati who is pure blood knows muggle novels.

Harry took the opportunity, he created an ice saw to cut off the wings of Mercphobia that made the water dragon god fall to Earth.

"Ice Cage"

The ice Cage is an S-level sealing technique that Harry is able to use, this technique will lock living things inside him including their magic so that they can no longer use magic. This technique is deadly to magical creatures including witches because they depend on their magic, if their magic is lost or sealed suddenly, their bodies will be shocked and they will experience paralysis for several days and then die.

Fortunately for Harry, Mercphobia is a dragon, not a random dragon, but rather the God Of Water Dragons, the strongest Dragon in water magic.

Mercphobia's magic is indeed sealed, but she won't die because the physiology of Dragons is fundamentally different from humans, it is because of this that Dragons won't die even if they spend months in an ice cage, weakened? sure, dead? no.

"I didn't know ice could be so dangerous," Zacharias Smith said.

"Zach... Don't you know that there are people who die from the ice spell of Glacius?"Susan asked hesitantly to her house mate.

"I'm sorry, Mercphobia, for being like this... I can only take your power by force" said Harry. His hands glowed with golden light.

Harry uses the Potter family's magic to take Mercphobia's magic and make her magic his own. At the end of the process, Harry possesses the killing magic of the water dragon god, in addition to his Phantasm Magic.

The Potter family is one of the twelve founders of the wizarding world, the family of the creator of the wizarding world, the one who has spread magic, gives magic to others, therefore, too, The Potter family has the right to take someone else's magic.

"Impossible... How is that possible?"

"Catch them! Their brackets in Azkaban" cried fudge fearfully staring at the Potter family, he was supported by Lucius Malfoy and Dolores Umbridge.

Fudge's remarks supported by Lucius and Dolores made James Potter's eyes squint. His magic Aura spread in the air which made the students gasp for breath, some also fainted.

"How dare you... You Dirty Half-Breeds!" hissed James. He points his wand at Fudge and his two henchmen which makes the three of them scream in pain.

"What..? What are you doing to me, Potter?"Lucius hissed in pain.

"I just took your magic, you filthy peasant," said James flatly.

"Anyone who tries to touch the Potters, by a hair's breadth, will deal with me," James said, making veterans shiver because, for the first time, they saw the figure of Charlus Potter in James Potter.

'This is not good... thought Dumbledore worried as his plans began to unravel. He needs Malfoy to support Tom when Tom gets back on his feet, he needs the fool Fudge and his pet Toad to keep the Wizarding World pressed by Tom for his upcoming plans, but with James taking their magic they are practically useless. He certainly knew about the Potter family's magic-taking ability, that was the reason why he killed Charlus Potter before he could take his magic, that ability made him afraid and jealous, he had tried repeatedly to replicate the technique, but he still couldn't do it.

Harry stared at Mercphobia in agony as all his magic had just been taken. Mercphobia's body glows and transforms back into a human.

"You were there, right?"Harry asked the woman accompanying Mercphobia. "I've taken all his magic, he's practically a human now, you have to take care of him" said Harry who then went to the Ancient Dragon Guild by riding Minazuki to report the first stage of his mission.

"You know, if the Water Dragon God alone is this strong, I don't want to know how strong the other Dragon gods are," said Ron, who was regarded by others, especially the Potters who were worried about their son or brother.

"It is likely that the weak ones are either The Wood Dragon God or the Moon Dragon God, although I doubt they will be dubbed Dragon Gods if they are weak," Su said.

"Indeed, it seems that we cannot underestimate them, they got the nickname of gods obviously not because they can only shoot fire," Padma said nodding in agreement with the thoughts of her housemates.

"Since this chapter is over, we'll have dinner first and then rest," Dumbledore announced to the dismay of the students, but the teachers and other adults agreed that the students, especially the little ones, needed a rest.

Dinner begins, and when the students are ordered to go to bed, Dumbledore uses a large-scale light sleep spell that stops all conversation. Dumbledore plans to erase the Potter family's memories, but he knows that the Potter family's Magic will turn to attack him if he touches the Potter family members, no matter if James and Charlie are categorized as blood traitors of the Potter family.
