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

When Chu Xuan moved the Soaring Flood Dragon King into the Great Dao Communication Group, the Soaring Flood Dragon King's eyes suddenly opened and his aura erupted.

The Soaring Flood Dragon King was shocked.

Someone had actually absorbed a wisp of his aura and connected him to a mysterious object.

This person was definitely much stronger than him!

Was there actually such a terrifying expert in this world?

Chu Xuan then introduced the Soaring Flood Dragon King in the group chat.

"Welcome Fellow Daoist Soaring Flood Dragon King. Being able to join this group is fate."

"Eh, it's that shameless green snake?"

After he overcame his initial shock, the Soaring Flood Dragon King quickly gained an understanding of what this group chat was about.

Then, he saw an acquaintance appear.

"B*stard Mo Tu, are you insulting me?"
