Seeing the obedient demeanor of the two children, Wong felt much relieved. At the very least, they were willing to listen to the advice of an elder like him.
"From now on, aside from certain books on the shelves sealed with chains, you are free to read any book in the library."
"The sea of knowledge is boundless. May you soon become masters of the Mystic Arts."
After offering his blessing, Wong turned and walked out of the library to continue supervising the apprentices' training.
Harvey nodded rather casually. Watching him leave, he turned back and began discussing the theory of opening dimensional portals with Hermione.
"When using portal magic, you need to have a detailed cognitive understanding of the location you want to go to. Your mental state is clearly off..."
Hermione listened with a serious face. She was deeply fascinated by this novel Mystic Arts magic.
However, after trying several times, her portals remained unstable. She said in frustration, "But I've already tried my hardest to picture London..."
"London?" Harvey looked surprised and pointed out her mistake. "That is the London of another world. No wonder you're failing. You have to picture the London of this world..."
In truth, Harvey didn't think the upper limits of the Mystic Arts in the Marvel Universe were all that impressive.
After all, a sorcerer essentially had to take out a "loan" to use the Mystic Arts.
And a loan always has to be repaid sooner or later.
Otherwise, did people really think the Vishanti, one of the three ancient gods of the Marvel Universe, did good deeds without expecting anything in return?
That would be too naive.
It is well known that almost every sorcerer who borrows power from the Vishanti doesn't meet a good end.
Even after the Ancient One died and became a spirit, the Vishanti wouldn't let her go.
On the surface, the Ancient One's explanation was that following the God of White Magic, the Vishanti, in spirit form would allow her to better study and research magic.
But in reality, if given a choice, who would willingly become someone else's lackey?
From the moment the Ancient One borrowed magic from the Vishanti, her future had been sealed!
Therefore, Harvey's interest in the Mystic Arts wasn't exceptionally high.
To him, the Mystic Arts were more of a supplement to his overall strength.
He could learn it, or he could not.
He was far more drawn to researching the true nature of magic itself.
For example, exploring the connection between magical power and spells, the link between magical power and a wizard's bloodline, the fundamental nature of magic in both worlds, or attempting to create his own spells.
Unfortunately, his innate talents weren't outstanding enough.
If he were like Wanda, the Scarlet Witch, born with Chaos Magic, Harvey wouldn't need to research the "true nature" of magic at all.
Simply researching himself would be enough to elevate his power to an omniversal level, second only to the One-Above-All (OAA).
As the saying goes, the rich rely on technology, the poor rely on mutation.
So Harvey could only rely on magic.
Furthermore, the magic of the Harry Potter world might seem childish, but it was actually profoundly deep.
For instance, the Time-Turner involved the very essence of time and space.
And Avada Kedavra, seemingly a simple piece of dark magic, actually involved the essence of the soul.
There was even Transfiguration, which at its highest levels could turn inanimate objects into living beings, clearly touching upon the essence of life itself.
So, to Harvey, as long as he could thoroughly research and understand the fundamental nature of spells in the Harry Potter world, even if he didn't become a freak of nature like the Scarlet Witch...
At the very least, he should be able to protect himself and survive the Purple Titan's snap crisis.
——————————————
In the quiet library, the two children, wearing Sling Rings, were gesturing with their hands while conversing in low voices.
Time always flies when studying magic.
In Hermione's perception, she had only just figured out the principles of opening a dimensional portal and barely managed to cast one that reached a few kilometers away.
Then she realized it was already evening.
Glancing at the dim light outside the library window, Harvey stopped the discussion.
"It's getting late. We should head back."
Hermione subconsciously rubbed her growling stomach. She hadn't eaten since morning, and even a wizard's physique couldn't handle that.
"Let's go back then. We didn't go home for lunch; I wonder if Mom noticed?"
"It doesn't matter. Worst case scenario, I'll just solve it with an Obliviate."
Hermione's tone changed instantly. "No! How could you use a spell on my mom?"
"Alright, alright. Then we'll just honestly take our scolding."
After bantering with Hermione for a moment, Harvey left a note in the library explaining their departure to Wong.
He was just preparing to open a cross-world portal when...
He suddenly froze.
What if he got teleported into the vacuum of space again?
After thinking it over, he felt that shouldn't happen a second time.
Logically, his "cheat code" shouldn't be so inconvenient.
If he could visualize the detailed scene of Hermione's house in London, he shouldn't be thrown into outer space.
But necessary precautions still had to be taken.
"Protego!"
Harvey gently waved his wand, casting two Shield Charms over himself and Hermione.
"Magic Shield!"
Then, using his left hand wearing the Sling Ring, he conjured two golden magical shields.
Once everything was ready.
Harvey began to visualize 8 Heathgate Street in Hampstead Garden Suburb, London, in his mind.
A portal shimmering with blue light appeared and gradually expanded.
The portal opening this time was much gentler, without repeating the violent suction that had dragged them in before.
They could even see through to the other side—standing in the bedroom were the utterly bewildered Mr. and Mrs. Granger, alongside a shocked Professor McGonagall!
The moment she saw her mother, Hermione's little face was filled with terror.
Even Harvey's usually steady heart skipped a beat. He quickly grabbed the hem of Hermione's clothes and pulled her through the portal.
As the portal radiating mysterious blue light vanished.
Harvey, keeping his head down and playing dead, and a terrified-looking Hermione obediently stood before the Grangers and Professor McGonagall.
Seeing her daughter safe and sound, Mrs. Granger's fearful and anxious heart finally settled. She hugged Hermione and asked softly:
"Darling, you're finally back. Where did you go today? I was worried sick all day..."
Hermione leaned against her mother's warm waist, stammering, unable to speak.
Professor McGonagall stared intently at Harvey and questioned him sternly: "Young Mr. Ferguson, the scene on the other side of that portal just now... seemed to be some sort of library?"
He absolutely could not expose his greatest secret.
Harvey steeled his resolve and remained silent.
Simultaneously, he gripped his wand tightly in his hand.
If any unexpected situation arose, he would be able to counterattack immediately.
Professor McGonagall noticed the little boy's vigilance. Her expression softened, and she switched to a gentler tone, saying:
"Extraordinary talent is a wizard's greatest wealth. As a professor at Hogwarts, I hope, child, that you will not stray onto the wrong path in the future."
"Furthermore, if you are going to leave the house next time, at the very least remember to inform your elders beforehand."
His tense mood relaxing slightly, Harvey nodded and said with a look of deep shame:
"I am sorry, Professor McGonagall. I shouldn't have taken Hermione out to play without permission. I will say something beforehand next time."
"There will not be a next time!" Mr. Granger said in a strict tone.
"Mrs. Granger, Mr. Granger, since the children have returned safely, I should head back to the school."
Professor McGonagall, belly full of questions, hurriedly bid farewell to the Grangers and Apparated back to Hogwarts.
