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 did exactly as he thought. He immediately derived a low-level incarnation technique from the Myriad Incarnation technique.

After more than an hour of refinement and tweaking, the new incarnation technique was finally created.

The low-level incarnation technique would allow its wielder to create up to three original-body incarnations. The strongest incarnation possessed seventy percent of the original body's strength, and its mind would be linked to the original body.

As for the power source of the incarnation, apart from the original body providing a part of the power, the rest of the power came from the laws of Heaven and Earth.

It could create 12 incarnations at most from external objects, whose strength would not exceed 60% of the original body's.

The wielder could send a wisp of their soul into incarnations.
