Villain: Possessing the God of War from the Start

When college student Hu Chen was complaining about a god-clan war god in a novel he was reading who shared his name, he slipped on a banana peel and fell. When he opened his eyes again, his soul had transmigrated into the body of the war god, who had been dead for fifty thousand years. This war god is now good for nothing but his strong body. He has no cultivation, and demonic energy has invaded him. If anyone discovers him, he's as good as dead.

Luckily, Hu Chen gets the standard issue for transmigrators: a card-drawing System.
