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

By the time Chu Xuan emerged from his cultivation, the 81-year milestone had arrived.

"You've remained in seclusion for 81 years. Your strength has improved greatly. You have been rewarded with world origin energy and the chaotic energy of creation."

In addition to the world origin energy, the reward for the 81-year milestone was a ball of the chaotic energy of creation, which was of higher quality and amount that Chu Xuan possessed.

As usual, Chu Xuan infused the world origin energy into the Heavenly Dao laws, stimulating another round of changes.

Taking out the chaotic energy of creation, Chu Xuan split it into two portions. Half of it was absorbed into his body.

The other half was incorporated into the Origin Dao Ring's Great Dao, which began to transform and derive more laws.

Chu Yi and Chu Er even benefited directly. Soon, they would reach the 10,000-mile mark.

After that, Chu Xuan started cultivating again.
