MTL - Marvel: Anime Extraction - Chapter 376 interrogation

Chu Xuan transmigrated to a fantasy world and became the young master of a powerful family. He was rebuked for misbehaving just because he sneezed during a banquet. As punishment, he was banished from the ancestral mansion and was relocated to a remote residence.

He did not mind the punishment at all. He just needed a spot that could allow him to be a shut-in. With the system that would allow him to grow stronger by being a shut-in, the longer he stayed indoors, the more powerful he became.

After being a shut-in for a day, he was rewarded with the Indestructible Body Technique.

After being a shut-in for a month, he was rewarded with the Immovable Mountain Technique.

After being a shut-in for a year, he was rewarded with the Yuxu Celestial Scripture and 100 years of cultivation.

After being a shut-in for 10 years, he was rewarded with the Chaotic Indestructible Body and the Bell of Chaos.

…

Chu Xuan declared, “No one can make me leave my home. I like being a shut-in!”

One day he suddenly found himself in hell.
All he had was the desire to live and a predation ability.
From the first to the ninth thousand circles of hell, he absorbed dozens, hundreds of thousands of demons.
Even the seven great dukes of hell bowed down before him.

– Why would you wish to go back? Doesn’t his highness have everything that’s in Hell?
– What do I have?

Nothing to eat, nothing to enjoy!
The only things in Hell are the barren lands and terrible demons!

“I’m going back.”

After ten thousand years he returns to Earth.

A teenager named Evan Mason was reincarnated into the magical world of Harry Potter and goes to school at Hogwarts!
With only his knowledge of the future and great talent for magic, he takes the path towards the top of the magic world, only to realize that ever step he took, changed everything!
