MTL - I Was a Group Pet In 80 - Chapter 1 Is it wrong?

I, a HIKKI-NEET, suddenly reincarnated in another world as a prince, and was immediately deemed the weakest ever, with my life already in a pinch after being abandoned as a baby, being stared down by a huge beast!?

However, I could only use one kind of magic. It was close, but I was able to avoid a “dead end” in my first few days of being born using that magic.

Anyways, I just want to live a lazy shut-in life as an adopted noble with my one all-purpose magic, but…?

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!”
