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 stopped infusing spiritual power into the Myriad Heavenly Mirror. After a few days of attempting random connections, he finally got in touch with another expert.

It was a Supreme realm expert called Du Yuan from the Western Region.

Chu Xuan had become addicted to masquerading as a senior expert. His regal demeanor stunned the other party.

He affixed one of the Myriad Heavenly Mirror's marks on Du Yuan's body so that he could locate the other party at any time.

Through the conversation just now, Chu Xuan found out that the Southern Region he belonged to was part of the Northern Zone of the nine zones.

Du Yuan was also located in the Northern Zone.

He did not have a formidable background, and was currently a guardian of a family in the Western Region.

This was because, when he was young, he had received assistance from the previous family head. As such, he was obligated to protect this family's well-being.
