I thought I could be a mage quietly, but in the end I had to cultivate both magic and martial arts. They all say that if you want to cultivate both magic and martial arts, you should cultivate both magic and martial arts, but the system that needs to be awakened is the performance system.

Leveling up and fighting monsters all the way, he was eventually recognized as a poisonous mage in the cloud world. This novel and its characters are purely fictitious.
