Half a clear breeze

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!”

I Stayed At Home For A Century, When I Emerged I Was Invincible

"The little evil King was blessed by luck and has entered the lucky mystic realm that you set up. Because of your prank, he has castrated himself with his sword, You have been rewarded with the Blood Rebirth technique."

Chu Xuan was cultivating when the system's reward suddenly arrived.

Chu Xuan was momentarily stunned. The little evil king had actually entered the lucky mystic realm that he had set up?

Moreover, he had castrated himself with his sword?

Thinking back to the prank he had set up back then, he had thought that no one would be so foolish as to castrate themselves after reading just one page.

In the end, there was really a fool who had castrated himself after reading one page!

Chu Xuan did not know how the little evil king would feel after reading the rest of the manual's contents.

He reckoned that it would definitely not be good.
