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

Somewhere in the central section of the Heavenly Sun World, Qi Le and Chu Yu held hands as they traveled along.

A figure followed behind them, and Qi Le stopped in his tracks.

The figure behind him immediately ran forward in a flattering manner.

"Grandnephew, do you have anything you want?"

The grand elder had a flattering smile on his face.

"I already left the Li family, so why are you following me? If you want to restore the Li family's reputation, you can go ahead and attack."

"What are you saying?" the grand elder said sternly, "You may not be a member of the Li family, but you are my grandnephew."

"It's perfectly normal for me to protect my grandnephew. The reputation of the Li family is unimportant in comparison."
