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

Ding Yue snorted coldly. He did not pay any attention to the purple-clothed woman's rage, nor the red-bearded old man's murderous gaze.

He lowered his head to look at Ying Jiankong and said, "This is the gap between you and me. If you want to catch up with my pace, you should first start by breaking through to the first stage."

He did not believe Ding Yue's words at all. He felt that Ding Yue was teasing him.

What? Forget about his sweetheart? That was simply ridiculous.

"Ding Yue, if you want to kill me, then kill me. Don't even think about disturbing my sword heart!"

Ding Yue sneered and said, "Kill you? Are you even worthy of dying by my blade?"

Sword intent surged forth from his body into the sky. In that instant, Ding Yue looked like a peerless divine sword that stood between Heaven and Earth.

The edge of the sword was sharp and invincible!
