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!”

"Could these legends have appeared after the last Great Dao calamity?"

"No, that person said that this was a legend from the beginning of the world. You should know that after the Great Dao calamity, when all of our races were expelled from the nine zones, no such experts were born," Hong said, shaking his head.

"Besides, we have all been monitoring the nine zones since then, so how would we not have heard of such a legend?"

It was true. After the last Great Dao calamity, each race had kept a close eye on any changes in the nine zones, and they all had their own ways of obtaining information.

This was the first time they were hearing of these legends.

It had to be related to the changes in the nine zones.

"Was there really no world before the creation of the nine zones?"

A Previous World?
