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!”

Back in the cave, the light in Yang Tian's eyes began to dim, and the original Yang Tian regained control of his body.

"Kid, your cultivation level is decent, but your cultivation foundation isn't strong enough. Work hard and you won't have any bottlenecks before the seventh level."

Since he had such a powerful ancestor, why was he born with such a lowly background?

"It's been a long time. A very long time."

Then, the voice fell silent, as if it had never been there in the first place.
