Mechanical Alchemist

[Magic + Alchemy + Adventure + No Heroine + Genius + Academy + Different World] (This alchemy is just a setting, there is no specific production process, and the mechanical elements are similar. It just means that the protagonist can make something similar to a war fortress in the later stage, but the specific process will not be written.) Yin Hong, the young master of the Yin family, one of the four major families in Lieyang City, is a time traveler himself. He traveled to this world 12 years ago and learned magic and alchemy in this world. He is about to explore new possibilities in the world.
