Magic Lending

That was right. Harry could indeed use contracts to share his Magic Power with others.

The Supreme Mage called this ability lending, an ability unique to Dimensional Demons.

The Chaos Magic within Harry was extraordinarily unusual, beginning with its inconceivable quantity.

According to the Supreme Mage, the Chaos Magic within Harry seemed to exceed even that of some weaker dimensions, and it was still growing exponentially with every passing moment.

If Harry could perfectly control the magic within him, he could easily destroy planets and become the most powerful Supreme Mage.

But Chaos Magic was far too disorderly. Chaos was its very nature. In that world, so long as Harry dared to use more magic than he could control, his magic would completely run wild, causing immense and irreversible damage to the surrounding environment.

Once, the Supreme Mage had taken Harry to a hell dimension. There, Harry completely activated the magic within him, and his power had nearly torn that hell dimension apart.

Because of his disorderly magic, Harry had been unable to use many spells in that world, and lending was one of them.

No one knew when Harry's magic might lose control. When that happened, a borrower would be flooded with an enormous amount of magic their body could not withstand, causing them to explode like a balloon.

But in this world, although the amount of magic he could control had decreased, Harry's control had improved tremendously. It was now almost impossible for him to lose control.

Therefore, after some time spent studying it, he would be able to lend magic to others!

And Aunt Petunia, who longed for magic, would be his first borrower. Not only would this make up for Aunt Petunia's regret, but it would also allow him to reasonably "take revenge" on the Dursley family!

The wicked smile on Harry's face became increasingly obvious.

"You must remember that the fundamental principle of magic is equivalent exchange. If you borrow my power, you must pay the corresponding price.

"So, have you decided to borrow magic and become mages?"

The Dursley family stared blankly at Harry's smiling, childish face. That face looked the same as before, but all weakness had vanished from it, leaving only deep malice.

They felt as though they were signing a contract with a demon. Even knowing they might have to pay with their souls, they still could not cast aside their greed.

Gulp~

Aunt Petunia swallowed, staring fearfully at the nephew before her, who was both familiar and strange. She asked in a trembling voice,

"What price do we have to pay?"

Harry thought for a moment before answering,

"Since you're family, I'll give you a one-percent discount. Casting a low-level spell costs ten pounds, a mid-level spell costs one thousand pounds, and a high-level spell costs ten thousand pounds!

"You can also permanently purchase the right to use a spell. Just multiply the original price by a thousand.

"However, after casting a spell, you must shout, 'I'm an idiot!' That is the price of casting it!"

Hearing Harry's words, Aunt Petunia and Uncle Vernon looked at each other before asking in confusion,

"That's all? We don't need to pay with our souls, our lifespans, or anything like that?"

Harry rolled his eyes.

"What would I want with your souls? How much are they even worth? I'm not a Dark Wizard.

"Of course, if you want to trade with souls as currency, that's fine too. I have a complete trading system, fair to everyone.

"Since you're family, each of your souls can be exchanged for the permanent right to use one high-level spell."

"The permanent right to use a spell?" Aunt Petunia muttered, immediately doing the math. "One use of a high-level spell costs ten thousand pounds, and a thousand times that is ten million pounds. Oh my God, we're worth so much!"

Harry was momentarily speechless. Aunt Petunia's focus seemed somewhat strange, so he patiently explained,

"You're not worth ten million pounds. It's only because you're my family that your souls are worth that much.

"So? Do you want to trade with your souls?"

Harry's voice pulled Aunt Petunia out of her thoughts about the enormous sum of ten million pounds, and she hurriedly shook her head.

"No, no, no. We'd better trade with pounds."

Even in this day and age, the pound had considerable purchasing power. Simply using mid-level magic would be difficult for the already impoverished Dursley family to afford, but it was certainly better than trading with their souls.

Afterward, the Dursley family cleared out the room beside Dudley's and let Harry move in. After making slight modifications to the contract formation, Harry signed contracts with the Dursley family.

The contract contained only one sentence: the right to interpret this contract belonged solely to Harry Potter.

The Dursley family was extremely dissatisfied with this, but Harry forcibly suppressed them, leaving them no choice but to obediently sign the contract.

Harry's exact words were, "You lose nothing by signing it. You don't want to be Muggles for the rest of your lives, do you?"

Well, Harry had heard the word "Muggle" from Aunt Petunia.

It was obviously a word that discriminated against ordinary people, which worsened Harry's impression of this world's Wizarding World.

The Supreme Mage would never discriminate against mortals, and as the Supreme Mage's closest disciple, Harry naturally would not either.

After signing the contract, the Dursley family spent fifty thousand pounds to purchase the right to use five low-level spells. Aunt Petunia and Uncle Vernon each received one, while Dudley received three.

It had to be said that Aunt Petunia and Uncle Vernon spoiled Dudley far too much. That was not good; it could easily lead a child astray.

So whenever Harry had time, he would give Dudley a beating, while Aunt Petunia and Uncle Vernon watched from the side, angry but afraid to say anything.

After all, Harry had now completely replaced Uncle Vernon as the master of the Dursley family.

Soon, the neighbors and Harry's classmates noticed the change in him. Harry, who had once been constantly bullied, had suddenly turned things around. The Dursley family, who had once beaten and scolded him at every turn, now treated him respectfully, as though they were trying to curry favor with their superior.

Of course, what outsiders did not know was that Harry really had become the Dursley family's superior—and one who had signed soul contracts with them on the mysterious side of things!

Time passed quickly. After receiving fifty thousand pounds in pocket money, Harry bought new clothes and threw away all his old belongings.

In his newly renovated room, Harry continuously studied formations, trying to alter them and master new spells.

With the help of his stable Chaos Magic, Harry successfully modified several formations, raising his strength another level.

Time passed quickly. Just as Harry began to feel that life in this world was not so bad, he finally received the letter from Hogwarts School that Aunt Petunia had mentioned!

"Harry, Harry, there's a letter for you!" Dudley jogged over and handed the letter in his hand to Harry with a flattering expression.

After being repeatedly taught a lesson by Harry during this time, Dudley had finally come to understand Harry's former suffering and deeply regretted his actions.

Though Harry still bullied him constantly, Dudley now held Harry in the highest respect.

The magic Harry had given him was simply too useful. Telekinesis alone brought tremendous convenience to his life.

Although his telekinesis was only a low-level spell and could move objects weighing no more than ten kilograms.

Harry took the letter from Dudley, lowered his head, and saw the following words:

Surrey, Little Whinging.

4 Privet Drive, second-floor bedroom on the right.

Mr. Harry Potter, recipient.
