That's right, Harry could indeed share his magic with others through a contract.
This ability was referred to as "lending" by the Sorcerer Supreme, a power unique to dimensional demons.
The chaotic magic within Harry was extremely special, primarily due to its unimaginable quantity.
According to the Sorcerer Supreme, the amount of chaotic magic inside Harry seemed to surpass that of some weaker dimensions, and it was 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 Sorcerer Supreme.
But chaotic magic was too disordered, chaos was its very nature. In that world, if Harry dared to use more magic than he could handle, his power would spiral out of control, causing irreversible and massive damage to his surroundings.
Once, the Sorcerer Supreme took Harry to a hellish dimension, where Harry fully activated his magic. His power nearly tore that hell dimension apart.
Because of the disordered nature of his magic, there were many spells Harry couldn't use in that world, and "lending" was one of them.
There was no telling when Harry's magic might go out of control. If that happened, the borrower, unable to withstand the overwhelming surge of magic, would explode like a balloon.
But in this world, although the amount of magic he could control was reduced, Harry's mastery had improved significantly.
Therefore, after some research, he would be able to lend his magic to others!
And Aunt Petunia, who longed for magic, would be his first borrower. This would not only fulfill Aunt Petunia's regret but also allow him to "repay" the Dursleys in a justified way!
The mischievous grin on Harry's face grew wider:
"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 and become a wizard?"
The Dursleys stared blankly at Harry's smiling, youthful face. That face was the same as always, yet all traces of timidity were gone, replaced only by deep malice.
They felt as though they were making a deal with a demon, even knowing they might have to pay with their souls, they couldn't resist their greed.
Gulp—
Aunt Petunia swallowed hard, staring fearfully at her familiar yet now utterly foreign nephew, and asked in a trembling voice:
"What... what price do we have to pay?"
Harry thought for a moment before answering:
"Since you're family, I'll give you a 99% discount. Casting a low-tier spell costs ten pounds, a mid-tier spell a thousand pounds, and a high-tier spell ten thousand pounds!
You can also permanently purchase the right to use a spell, just multiply the original price by a thousand.
But after casting, you must shout 'I'm a fool' that's the cost of spellcasting!"
Hearing this, Aunt Petunia and Uncle Vernon exchanged glances, confused.
"That's it? No souls, lifespans, or anything like that?"
Harry rolled his eyes:
"What would I want your souls for? They're not worth much, and I'm not a dark wizard.
Of course, if you'd like to use your souls as currency for a trade, that's also possible. I have a complete transaction system, fair and square for all.
Since you're my family, I'll offer you a special deal: each of your souls can be exchanged for the permanent use of one high-level spell."
"Permanent use of a spell?" Aunt Petunia muttered to herself, immediately doing the math.
"A single use of a high-level spell costs ten thousand pounds. A thousand times that would be ten million pounds! Goodness, we're worth so much!"
Harry was momentarily speechless. Aunt Petunia's focus seemed oddly misplaced. He patiently explained:
"You're not worth ten million pounds. It's only because you're my relatives that your souls are valued so highly.
So, what do you say? Want to trade with your souls?"
Harry's voice snapped Aunt Petunia out of her daze over the enormous sum. She quickly shook her head:
"No, no, we'd rather stick to pounds."
Even in these times, the purchasing power of the pound was strong. Using intermediate-level spells was already straining the Dursleys' modest finances, but it was still far better than trading with their souls.
Later, the Dursleys cleared out the room next to Dudley's bedroom for Harry to move into. After making slight modifications to the contract's magic, Harry had the Dursleys sign it.
The contract contained only one clause: the right to interpret this contract belongs solely to Harry Potter.
The Dursleys were extremely unhappy about this, but Harry forced them into submission. His exact words were: "Sign it or miss out. Do you really want to stay Muggles forever?"
Hmm, the term "Muggle" was something Harry had picked up from Aunt Petunia.
Clearly, it was a derogatory word for non-magical people, which lowered Harry's opinion of this world's wizarding community.
The Sorcerer Supreme would never look down on ordinary humans, and as the Sorcerer Supreme's closest disciple, Harry held the same belief.
After signing the contract, the Dursleys spent fifty thousand pounds to purchase the use of five low-level spells—one each for Aunt Petunia and Uncle Vernon, and three for Dudley.
It was obvious how much Aunt Petunia and Uncle Vernon doted on Dudley, which wasn't good. Spoiling a child like that would only warp his character.
So, whenever he had time, Harry would give Dudley a good scolding while Aunt Petunia and Uncle Vernon watched, not daring to say a word.
After all, Harry had completely taken over Uncle Vernon's role as the head of the Dursley household.
Soon, the neighbors and Harry's classmates noticed the change in him. The once-bullied Harry had suddenly turned the tables, the Dursleys, who used to scold and mistreat him, now treated him with respect, almost as if he was their boss.
Of course, outsiders didn't know that Harry had indeed become the Dursleys' boss, bound by a soul contract in the mystical world!
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 tirelessly studied the magic, attempting to modify it and master new spells.
With the help of stable magic, Harry successfully altered several magic's, further enhancing his abilities.
As time flew by, just as Harry was starting to feel that life in this world wasn't so bad, he finally received the letter from Hogwarts that Aunt Petunia had mentioned!
"Harry, Harry! There's a letter for you!" Dudley hurried over, eagerly handing the envelope to Harry.
After being repeatedly disciplined by Harry during this time, Dudley had finally understood the suffering Harry had endured and deeply regretted his past actions.
Even though Harry still bullied him, Dudley now admired and respected him immensely.
The spells Harry had granted him were incredibly useful, even low-level telekinesis made his life so much easier. Though his telekinesis was only a low-level spell, allowing him to move objects up to ten kilograms.
Harry took the letter from Dudley and glanced at it, seeing the following address:
Surrey, Little Whinging.
4 Privet Drive, second floor, right-side bedroom.
Mr. Harry Potter!
