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!”

"Thirteenth Uncle, what's that?" Chu Pingfan asked curiously.

The Fengdu Ghost King looked very terrifying and gave off a sinister feeling.

"It's a ghost, a special existence."

Chu Xuan looked at Chu Pingfan, who had already grown into a youth, and said.

Chu Pingfan was extremely surprised.

Chu Xuan briefly described the unique points of a ghost.

Chu Pingfan was shocked after hearing it. He asked, "Are ghosts so powerful? And they can possess people too?"

"It's just that their abilities are quite special, but their flaws are very obvious. Once there's a method to specifically target ghosts, even if one isn't strong, they can still deal with ghosts that are stronger than them."

"Your Extreme Dao is very powerful. You won't be disadvantaged when fighting ghosts."
