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

Grandpa Zhang was not angry to see Hei Yue disappear. Instead, he bowed deeply and said, "Mister, you saved Yue'er's life."

Chu Xuan pointed at the teacup and said, "You can have a cup of tea and then go back to guard the Black Moon Tower."

Grandpa Zhang did not hesitate. He picked up the teacup and drank it in one gulp.

In an instant, many insights surfaced in her mind. His strength had actually improved a little, and the sixth level of the Divine realm was no longer unreachable.

He was extremely shocked. Just a single cup of tea had such a miraculous effect.

Just what cultivation level had this great expert reached?

"Thank you, Sir, for your great kindness!"

"You're welcome," Chu Xuan said with a smile.

"In that case, I will not disturb Sir. I'll head back and guard the Black Moon Tower for Sir!"

The Black Moon Tower was now completely under Chu Xuan's control.
