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

Chaos supreme realm experts were basically immortal. If he wanted to kill a chaos supreme realm expert, he would have to destroy their corresponding supreme law and cause it to change.

Even a chaos supreme realm expert could not change the supreme laws of the chaos.

This also meant that, under normal circumstances, no matter how strong he was, he would not be able to kill a chaos supreme real expert, even if the latter was weaker than he was.

He could suppress and seal them, but could not kill them. This was the uniqueness of the chaos supreme realm. Only those who transcended the chaos would be able to do so.

However, those who had transcended the chaos would have already left the chaos, and would have no reason to interfere with the matters of the chaos.

Therefore, unless the chaos was destroyed, or the supreme laws of the chaos were changed or destroyed, chaos supreme realm experts were immortal.
