Jiangshi: I Evolved Into a Demon in Japan

I transmigrate into the body of Old Master Ren, a zombie, and from the start Uncle Jiu has me laid out over a fire to burn. After activating the Evolution System, I make a beeline for a ship bound for Japan. Samurai and onmyoji are nothing but fuel for my evolution. While Uncle Jiu is still catching ghosts in the countryside, I've already evolved into a demon in the East and founded the ancestral home of the Corpse Path.
