Firearms Arcana: the Ignorant Princess

In a world where firearms and arcane arts coexist, Chen Yanchang, a graduate majoring in mechanics, pretends to be a wandering killer and breaks into an unusually strange city to launch a rescue operation for his brother. However, what he didn't expect was that the person being disguised was in more trouble than he was. Trapped in double trouble, he faces the biggest crisis of his life. In the northern capital of the Daxin Empire, there are many arcane mages. Chen Yanchang, who has no arcane skills at all, can only hold on to his gun. Arcane mage? What I fought was the arcane mage.
