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 took out some Supreme realm cultivation pills, as well as the pills for breaking through to the Heaven realm, and gave them to Chu Yi. He would have Chu Yi pass them to Du Yuan.

Currently, Du Yuan, was serving as an expert in the Black Moon Tower's guard division, and overseeing the Black Moon Tower of the Southern Region.

He had been awaiting Chu Xuan's instructions.

Before the Asura Ancient Land opened, it would not be hard to raise Du Yuan's strength to the Heaven realm with the aid of pills.

Those who ran errands for him had to at least be Heaven realm experts.

Otherwise, how could they be worthy of their status as big shots.

Apart from medicinal pills, Chu Xuan also got him to hand over a communication talisman to Du Yuan.
