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

At this moment, Chu's world manifested and transformed into a sword.

This was the first time Chu had revealed his abilities.

Before that, even if he attacked, and even if he was in danger, he had not gone all out.

At this moment, he had reached a point where he could not retreat and where no schemes would help.

This sword seemed to be restraining his Dao path.

Chu's world had extremely strong defensive and restraining powers.

After it turned into a sword, it gained an incredible amount of offensive power.

In front of Shui Lian, a wave of light rippled. Her expression was firm, and she had no intention of retreating.

The nine tails behind Mei spread out into space like nine Dao paths.

She sighed and said, "Where else can I go? I can only follow you."
