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 heard this and thought of something.

"How many years would it normally take for a native of the Heavenly Sun World to reach the Transcendent Dao realm?"

Lie Tian knew why Chu Xuan asked this.

"Based on what I know, the fastest person to break through to the Transcendent Dao realm in history was a million years!

"This is a record created by a Dao Supreme realm expert."

If he was born in the chaos and transcended the chaos in 10 billion years, he would only be 10,000 years old within the Heavenly Sun World.

A 10,000-year-old Transcendent Dao realm expert… how monstrous was that?

Lie Tian was filled with emotions.

"Although there might be ancient records that remain unknown, no matter how monstrous a genius is, a few hundred thousand years is the bare minimum."
