Sorry, Actually I Am the Final BOSS

Qin Ye always suspected that he was suffering from mental illness. I don't know from which day he found himself in an empty mental hospital. There is no doctor or patient here, just him and the incarnations of the seven deadly sins stripped out of his body. Each incarnation can lure evil people to take off their disguises and turn into evil beasts, allowing the beasts to obtain the souls of evil people, grow up, and then devour their power. This has become Qin Ye's only pleasure. "As long as you are a human being, you will have desires, and as long as you have desires, you can use them for me." Qin Ye put shackles on the desires of this world. Just when some people thought that these unstable elements were finally eliminated, Qin Ye walked out of the mental hospital. "I'm sorry, you guessed wrong. In fact, I am the final BOSS."
