Borrowing the Tesseract (Second Update)

"It's time to head back!"

In a room at the Leaky Cauldron, Jerry reached out and pressed the button to return to the main world.

He had actually hesitated over whether to bring Hermione with him this time, but after thinking it over, he decided against it.

This time, he might be gone for a very long time.

The Harry Potter World was where he had first learned magic, and it was also the foundation of all his magical research. Even mastering the lower-level laws of this world had taken him nearly a year, let alone those of other Small Worlds.

By the time he had mastered all the lower-level laws of every Small World, including the other worlds branching off from them, perhaps five or six years would have passed.

He had grown accustomed to the passage of time and did not particularly mind it, but there was no need to let Hermione accompany him out of selfishness.

Her parents, friends, and everything familiar to her were here. Taking her away so suddenly and making her unable to see her parents and friends for five or six years would not be good for her.

Hermione was only fifteen now. If she left with him and returned afterward, she would already be over twenty.

So, even if Hermione truly wished to leave this world with him for a long time, he felt they should at least wait until she broke through to immortality and could freely control her body's age.

In any case, as far as Hermione was concerned, Jerry had never truly left. Five or six years later, after he had gathered all the lower-level laws, fully completed his Small World, and gained his own dimension, he could return to this world—and the time here would still be now.
