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!”

Chu Xuan was surprised. Did Hong Yuanchu, who was one of the human race's ancestors, sense something unusual?

"Daoist Brother Chu, what's going on with the Great Daoyuan calamity of the nine zones? Why is it developing so quickly? Everything is progressing much faster than the previous Great Daoyuan calamities!"

"Also, what's going on with the human race? Why does it feel like the fate of the human race is at risk?"

He was one of the ancestors who had led the human race to become the overlord race. As such, the changes in the human race's fate did not escape his notice.

Based on his experience, such a situation should not have occurred during the early stages of the Great Daoyuan calamity.

During the Great Daoyuan calamity, Hong Yuanchu had used some means to observe the calamity and support the human race.
