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

Chu Xuan felt an intense sense of danger. If the blood fiends appeared in the Northern Zone and wreaked havoc there, they would definitely disturb his peaceful residence in the small courtyard.

He had to ensure that the Heavenly Dao laws covered the Northern Zone before that. That way, he would be able to change the laws so as to forbid the blood fiends from entering the Northern Zone.

Then, he used the Chaos Dao Mirror to deduce the time when the Great Daoyuan calamity would begin.

"The calamity will begin in ten years!"

Chu Xuan cursed inwardly. This was too fast. It was impossible for him to break through to the Daoyuan realm in ten years!

However, he heaved a sigh of relief. Ten years was enough for him to devour the Heaven and Earth of the Northern Zone.

Even if he had not, at the very least, he would be done with the Southern Region's laws.
