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

How did Du Yuan get involved with Xiao Liang?

From the looks of it, the two green-clothed men were chasing after Xiao Liang.

Their strength was at the second level of the Supreme realm.

Du Yuan's strength was also at the second level of the Supreme realm.

Fighting one versus two, Du Yuan was obviously not their match and had suffered some losses.

Chu Xuan was slightly surprised. Although Du Yuan was an itinerant cultivator, he had obtained a fortuitous opportunity and the cultivation technique he cultivated was not weak.

Even if the two men in green came from a major power with a storied history, Du Yuan should have been able to deal with them.

After interacting with Du Yuan for so long, Chu Xuan had a very good understanding of Du Yuan's capability.

He had once crossed a minor realm and killed an enemy who was stronger than he was.
