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…?

As the only magician and pharmacist on earth, Gu Feng’s life began to ripple…

Earning money is the easiest thing to do.

Got an incurable disease? Get a bottle of bright potion! Guaranteed instant recovery.

Worrying about exam results, worrying about going to school? A bottle of refreshing agent solves the problem, if you are not satisfied, you can return it in full! (Note: Chinese composition scores are not within the scope of the Three Guarantees)

Luxury cars, famous houses… these are not a problem for me.

And that long-legged girl, this is just a simple levitation magic, don’t stare at me with that kind of adoring eyes, okay?

Of course, it’s definitely more than that. Every magician is learned. Astronomy and geography, humanities and social interaction, food appreciation… everything is omnipotent and omnipotent. This article is guaranteed to be cool and exciting!

- Description from novelbuddy

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!”
