I Really Don't Want to Work for the Underworld Company.

My name is Yu Renhe, an unlucky guy who worked in an assembly line factory after being released from prison. Bullied by my supervisor and betrayed by my girlfriend, I thought my life had reached rock bottom until late that night when I witnessed my roommate transform from a "human" into a "monster that eats skin and drinks blood" Forced to join the underworld company to work for him. I woke up in a hospital bed, my wounds healed at an abnormal speed, and the unknown existence hidden in my belly was whispering. With his intact soul, he embarked on the "mission in the underworld" assigned by the company. When a living person embarks on the road to death, every step he takes is to step on the thunder between the world and hell. Can I survive until the day I get my soul back? Or will he be swallowed up by the human heart of the Yang world or the rules of the Yin world first?
