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 Black Moon Tower was famous for its efficiency, yet Hu Quan had waited for a few days without any results and therefore personally came to Chu County.

"Black Moon Tower has always been famous for its efficiency. Although the Chu family isn't weak, it shouldn't be difficult for the Black Moon Tower to investigate the layout of the family's territory, right?"

"I hope Tower Lord Wan can complete the mission as soon as possible."

"Three days. I'll wait another three days. If there's no result, I'll cancel the mission!" Hu Quan said in a low voice.

"Don't worry, Sect Leader Hu. Our Black Moon Tower is famous for its efficiency and reliability in handling matters. You can rest assured."

Wan Chang patted his chest and promised.

Hu Quan left quietly. He did not dare to stay in the Black Moon Tower's premises.

This group of black-hearted people might sell him out to the Chu family, or perhaps even the Purple Moon Kingdom.
