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

At this moment, Chu gave the monster an idea.

"Brother Blackie, it's definitely difficult for you to eat him now. You can strengthen yourself before eating him."

As he spoke, he pointed at the experts on the demon race's side.

"Eat them first. After eating them, you'll become much stronger, right? At that time, you can come back and try to eat this fellow."

The monster's eyes suddenly lit up.

"Brother Chu, you're right. Then let's do this."

"That one looks like you, but it's too big. Can it be eaten?"

"You can't eat that. It's very silly. You can't eat it. You won't be smart after eating it."

"Oh, then I won't eat it. I'm smart. It'll be terrible if I become stupid!"

The monster turned into a cloud of black mist and spread out, directly sweeping towards the demon race's forces.

Mo Chi roared and attacked in a hurry.
