From Living in a Haunted House to Becoming a Villain

Cheng Yun, a college graduate, rented a haunted house. The remaining ghosts in it did not harm him, but just liked to make fun of him. "I work during the day, and you work at night, right?" "If you don't show up on a regular basis, on Sunday you'll be dancing like no one else!" "Damn it, I'll fight you. You dare to cut off my power before I save the design I just finished after working overtime!" The incompetent and furious Cheng Yun was involved in a strange fire after choosing to 'run away from home' By chance, he came back from the dead and became a trainee undercover agent. "The soul has passed away, and Yuyu returns to the underworld!" "My name is Cheng Yun, and I'm a shady guy. If you guys want to fight, I'll kill you!" From the black and white impermanence to the ten palaces of Yama, as long as the Yin virtue is enough, Cheng Yun can call for help. What? You ask me what should I do if my moral integrity is not enough? There is blue that consumes mana, but there is no blue that consumes blood. As long as your life is hard enough, there is nothing you can't do!
