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!”

"From today onward, you two will oversee the reincarnation and protect it. You can also use this opportunity to comprehend the Great Dao of Reincarnation and the Heavenly Dao laws."

"The reincarnation cycle has its own order and laws. You two only need to interfere when someone wants to circumvent or break those laws."

"From here on out, I grant the two of you the authority over the reincarnation cycle."

"Ji will be the Extreme Saint, and Hun You will be the Absolute Saint. The two of you shall guard the reincarnation cycle here."
