You Start with Koi, and You Can Become Stronger Even If You Play Poorly.

A ten-year-old boy can easily kill the demon dragon from another world while going out to buy roast duck. He looks like an ordinary person, but he is actually a peerless wizard in this world of cultivation. In order to hide his realm, he had to study and live in a low-key manner in an ordinary college. He does not strive for fame and wealth, is not competitive, and is indifferent to the pursuit of the goddess. It just so happened that such a person who had nothing to do with the world shouldered the heavy responsibility of saving this world. "Please, I just want to show off, do I still have to take action?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
