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

He did not seem to believe Chu Xuan's words.

"Tai, let me ask you a question. What's the name of the person you're thinking about?"

"Ha, how would I know? That name is taboo. There are only a few who know the name, and I'm not one of them."

"You're really not him?" Tai asked in a serious tone, "For real?"

"No, I'm not," Chu Xuan replied decisively.

Chu Xuan wondered if the first ancestor of the human race, Chu, knew the name.

"When did the human race have someone like you?"

"Or perhaps, you're not even human?"

"I'm here to chat with you. As for who I am, it's not important."

"Tai, your injuries are not light. Do you need me to give you some treasures to heal your injuries?"
