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

Breaking through to the eighth level of the Supreme realm meant that Chu Xuan was one step closer to the Heaven realm.

The Supreme realm and the Heaven realm were separated by a natural chasm.

It was even bigger than the gap between the truth realm and the Emperor realm.

Most importantly, breaking through to the Heaven realm would bring about a tribulation.

Only by passing through the tribulation could one break through to the Heaven realm. Otherwise, one would either die from the tribulation or be severely injured. Those who were injured would have their foundations damaged and they would forever remain in the Supreme realm.

Generally speaking, it was almost impossible to break through to the Heaven realm again, even if one was lucky enough to survive the heavenly tribulation after trying to break through the first time.
