The Invincible God of War of the System

Bai Wuchen, a young boy from Earth who accidentally traveled to another world, found that he was in charge of the God of War system. It's just that this system is a bit special. Weapons need to be designed by ourselves, and combat techniques also need to be created by ourselves. So there is an invincible God of War who holds an M4 Thor and uses all eight armors to fight the Beast King! This novel and its characters are purely fictitious.
