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

The demon ancestor was very strong, and someone who had transcended the World Creator realm and was close to reaching its limits.

Although Qin was a divine being of the Heavenly Dao, he was far weaker than the demon ancestor.

Under normal circumstances, with his level of strength, he would not be able to withstand a single blow from the demon ancestor and would die without a doubt.

However, as a divine being of the Heavenly Dao, he would be defeated, but would not die.

He held the halberd in his hand and looked straight at the demon ancestor without fear.

"If I was born in the same era as you, there's no way I'd be weaker than you."

"Whether I can kill you or not, we'll know after I try," the demon ancestor said calmly.

With the halberd in hand, Qin's aura erupted, and dazzling golden light surrounded his body. His Dao path appeared.
