In Another World, I Want to Be the City Lord

I, Qin Feng, accidentally traveled to this "magic-less" world. In order to survive, I sold my system to a mall. The abominable mall actually paid me in installments. I thought I would live an ordinary life without a system, but what I didn't expect was that the system recycling gift package the mall gave me contained several books, one of which turned out to be a magic book. I became the only magician in the world. Facing a powerful enemy, a fireball spell can solve it. Facing powerful monsters, if one fireball technique can't solve it, just throw a few more. There's nothing I can't solve. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
