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

After defeating his clone, Chu Xuan tried to challenge an ordinary first-level Heaven realm expert.

Chu Xuan unleashed his full power and finally killed the Heaven realm martial artist.

The price was that he had also suffered heavy injuries.

"I should have broken the record by becoming the first Supreme realm cultivator to kill a Heaven realm cultivator."

He had gained a new understanding of his own strength.

After realizing how powerful a Heaven realm entity was, Chu Xuan could not help but feel lucky. Back then, Mo Tuo's soul had been heavily injured and had fallen from the Heaven realm.

If it had not, Chu Xuan would not have been able to suppress him!

It was also because Mo Tuo's soul had been weakened by the long period of hibernation and inactivity, which resulted in the strength of his soul becoming weaker.
