"Ideryuu no Houkou"

Harry used a breath attack on his enemies. He was currently on the edge of the Peregrande Kingdom, one of the kingdoms in Isghar and the largest kingdom in Isghar, as well as the location where he carried out his first S-class mission.

Harry took an S-class mission two weeks ago, that mission was a mission to catch a swarm of wizard killers, a magic-hating cult that thought that magic was the power of the devil and wizards were devil worshipers, this movement also appeared in areas that generally worshiped the power of holy.

Harry thought this was strange, because the Kingdom of Peregrande had far more wizards than the Witches of Fiore so the inhabitants should be used to seeing magic, there was no reason for them to hate magic and wizards unless they had suffered at the hands of wizards who used magic before.

'Maybe it was jealousy that caused them to attack and kill wizards' thought Harry, he really couldn't feel which of the people in front of him, it looked like they didn't really have magic because he didn't see any of them using magic.

The treatment between people who had mana and those without mana was indeed different, people who didn't have magic were often discriminated against because of their lack of mana. As a result, bullying sometimes occurs which will make anger and hatred flare up in the hearts of the manaless.

Wizard killers are dangerous not because they are strong, but because of the magic neutralizing artifacts they possess. Even Harry had a little trouble with them. Luckily the range of the neutralizer wasn't too far so Harry could attack from a distance although his spell repertoire was limited as the power of the neutralizer would last for a few hours.

"Damn... How could he beat us" said a wizard killer.

"Don't be afraid, he's already weakened, look, he looks out of breath" said another wizard killer. It was true what the wizard killer said, Harry was starting to show signs of mana disturbance which was marked by difficulty breathing because the mana he had was disturbed due to the magic neutralizer.

'Hmmm... They're pretty smart' thought Harry. He glanced at the wizard killers with slight displeasure, he knew that he could defeat them, but a smart enemy was far more dangerous than a strong enemy.

The wizard killers used anti-magic bullets to attack Harry. The anti-magic bullet was created from melted magic neutralizing artifacts, all wizards hit by the bullet would suffer damage to their magic circuits. Harry knew that he was in danger, that's why he turned things into iron to block the bullets.

Their attacks didn't stop there, they also attacked Harry with their anti-magic chains. Because wizard killers didn't have magic, so they wouldn't feel the effects of the chains containing anti-magic.

The battle continued, Harry had defeated more than 30 of the wizard killers, but there were still more than 30 other wizard killers, he wasn't sure how many wizard killers were in their group, but he definitely wouldn't let any of them escape.

"Concept Materialization : Destruction || Concept Materialization : Repulsion || Concept Materialization : Increased Attack Power"

Harry destroyed the surrounding area, using resistance to aim the damaged items at the wizard killers, then increasing the damage of the damaged items.

The wizard killers were showered with rocks and wood which had increased damage, plus the power of rejection increased speed which of course also increased the damage from the ruins.

After fighting for several hours, the wizard killers were finally defeated.

'Huft... Fighting them cost me more mana than I thought' Harry thought. He bound the wizard killers with the iron chains he carried, he didn't want to test his luck by binding them with magic, in case they still have other partners who have magic neutralizing artifacts. But to be more certain, he used the concept of truth and the concept of knowledge to access their memories and knowledge. Luckily, the seventy people here were all wizard killers present, they believed that no wziard could beat them as long as they had a magic neutralizing artifact so they didn't have to worry about anyone finding out where they were hiding.

Harry rested for a while, he didn't forget to summon the wolves he tamed to keep an eye on the surroundings, it would be dangerous if people attacked him while resting.

After resting for an hour, Harry who had finished resting left immediately after making a written report, he didn't want to forget anything even though he actually had an eidetic memory so unless there was mind magic or memory magic involved, it was impossible for him to forget anything, he summoned several wolf and told them to ride the wizard killers, He also rode them and brought them before King Peregrande who gave this S-class mission.

Peregrande Palace

Peregrande Palace was one of the most magnificent places Harry had ever seen. This palace is dominated by blue and white instead of gold like palaces in general.

"So they are the wizard killers who killed the palace wizards as well as my daughter?" asked King Peregrande after reading Harry's report. The current King of Peregrande is Leonardo de Peregrande is a man who looks in his 20s even though he is actually 40 years old. Leonardo was very angry at this time, his youngest daughter died at the hands of these heinous people just because his daughter could use magic, there was no prohibition for the royal family to possess and use magic, but these idiots dared to kill his daughter, his beloved daughter.

"Yes, Your Majesty" Harry said submissively, even though his ego refused this to happen, he is a Potter and a Potter does not submit to anyone, not even if he is a sovereign King or Queen.

"Good job Mr. Potter... You have done a great service to the Kingdom of Peregrande... You will be rewarded for this... I will pay for your mission, please wait for a week" said the King of Peregrande to which Harry nodded, Harry knew that King Peregrande had respect, it would be impossible for him not to keep his word, that's why Harry voluntarily returned to his inn, the Boar Inn.

Lumina City

The city of Lumina is the capital of the Kingdom of Peregrande, This city is based on the name of the Fairies of Moonlight who serve the Goddess Lunaria who is the Goddess of Moon and Night. Lumina City was the largest city in the Peregrande Kingdom.

Harry spent some time in this city, he went around the city, he did not intend to buy any more keys because he had handed over all his keys to Lucy and it was time for Lucy to try to get a new key, even though it probably wouldn't take long for Lucy to get one new because he often does missions with Natsu who often takes missions outside the city.

Boars Inn

The Boar Inn is one of the inns that is rarely visited in the Capital because the owner is still a child named Meliodas, even though he is a child, Harry knows that Meliodas is not a child, he is not even a human, his presence is similar to that of a demon. Not only him, some of his employees are also not human like King who is a fairy, Diane who is a giant race, Gowther who is a homunculus, and Elizabeth who is a race of angels. The only humans among the employees are Merlin, Arthuro, Escanor and Ban.

Although Harry was surprised to hear the name Arthuro as he had the name Pendragon behind his name, the people of this world might not know that the name Pendragon was the name of a king of Great Britain who was nicknamed the once and future King and also the king of knights. Not only him, Harry was also surprised to hear Merlin's name, he didn't know if this Merlin was on par with Merlin in his old world, although he didn't want to admit it, Merlin in this world was much stronger than himself, but he was sure that he could surpass Merlin in this world in a few years.

"Ara... Handsome boy, do you want to order dinner?" asked Merlin of Harry who came downstairs after a shower

"I want to explore the city tonight, maybe tomorrow" said Harry which made Merlin sigh in dissatisfaction but said nothing.

Harry went out to explore the city on the night.

One week later

"Mr. Potter, After considering your contribution to the kingdom, you are hereby allowed to enter Peregrande indefinitely, you also get the right to use 60% of the public facilities in Peregrande for free... In addition, I hereby grant you the title of Knight for helping the Kingdom, you don't know how much the meaning of capturing the wizard killers is to the Peregrande Kingdom, if anyone finds out about the Peregrande Kingdom letting the wizard killers roam freely for decades, Peregrande's integrity will decrease drastically and the wizards in this kingdom will leave and the tourists nothing will come that will cause many sectors to be unable to run which will impact the economy of the Peregrande Kingdom" said King Leonardo which surprised Harry. He did not expect that he would be awarded the title of knight.

"As for your mission fee, as stated in the mission paper, that is 16 million Jewel," said King Leonardo, handing over the bottomless bag containing the money agreed beforehand. Harry didn't need his magic to know that the pouch contained 16 million Jewels, there was a red cloth which was the mark of the cloth of oath which sealed the bottomless pouch.

"Thank you, Your Majesty" Harry said to which King Leonardo nodded.

"Now, upon the appointment of Sir Hadrian as a Knight, we will feast," said King Leonardo, whose people, especially the nobles, were pleased that their finances would be secure now.

The Royal Family and the nobles partied late into the night, Harry also joined the party because the star of the day's party was him, it would be impolite if he refused the King's party, he would rather not be the cause of war between Peregrande and Fiore because he knew that Fiore would be devastated considering Peregrande had twenty times more troops than Fiore's army including its wizards.

Fairy Tail

"Welcome Sir Hadrian, News about a Fairy Tail wizard being awarded a Knight title is circulating" said Makarov chuckling which made Harry blush, moreover the other Fairy Tail wizards joined in teasing him about his title.

"Oh come on, not you guys either, I've been teased by the station staff because of my new title" protested Harry which made the Fairy Tail wizards chuckle.

"Hmph.. Even though you like that" Natsu grunted which made Harry grumble to his fellow S-class wizards.

"Well done Harry, you did your first S-class mission perfectly" Mira said nodding to Harry which Harry nod in return.

"Let's have a party, for Harry's appointment as a Knight, and also for his success in his first mission" said Makarov who was greeted with excited exclamations from the other Fairy Tail wizards.

"WOOOO"

The wizards of Fairy Tail party all night long, Makarov is having a great time, his guild is usually associated with destruction and trouble, but thanks to Harry, the guild's reputation is being repaired given how little damage he causes.

Phantom Lord

A man with furious purple hair, he is Jose Porla, Master of the Phantom Lord Guild, as well as one of the ten holy wizards, the same position as Makarov who is also a holy wizard.

'Fairy Tail... How dare those damn fairies get ahead' thought Jose angrily.

He didn't expect that Fairy Tail would be even more annoying to deal with than it was worth. This sucks, let alone a Heartfilia of all the people joining, this will make Fairy Tail superior to Phantom Lord in terms of wealth alone.

What's more, those pesky fairies were starting to make a name for themselves, he had heard a lot about Titania, Majen, the Ice Empress, he had even started hearing about Oberon and the Salamanders. Meanwhile, the only famous member of the guild was Gajeel the Kurogane, the other elite four didn't even have the same fame.

This was really annoying, he wanted to destroy those fairies, but he couldn't do as he pleased if he didn't want the Magic Council to knock on his guild door. He needs a reason to attack Fairy Tail and destroy them.

'That's right, there is a way' thought Jose, grinning devilishly. If he can't attack Fairy Tail directly, then he only needs to attack Fairy Tail indirectly. He could afford the dark wizard to destroy Fairy Tail from within, he knew how much Makarov valued his guild members, Makarov would be destroyed if his members were injured or even died. A devastated Makarov will start blaming Phantom because he knows exactly who attacked Fairy Tail and started a war with Phantom, he can kill Makarov and the fairies under the pretext of self-defence.

'I'm a genius' thought Jose happily. He must gather a lot of dark magicians to start his plan, maybe his plan will be realized in two or three years, it doesn't matter to him, he can be patient, patience is his specialty.

What he doesn't forget is that every action has a consequence, he will pay the consequences of his actions, sooner or later. What's more, he forgot that Fairy Tail's S-class wizards were stronger than Phantom Lord's S-class wizards. He just had to witness first hand why Fairy Tail became the first ranked guild in Fiore, and when that happened, it was too late.
