I'm Guarding the Gate at the Soul-Suppressing Department

My name is Wu Fei, Kou Tian Wu, Flying Fei. My dad chose this name because he wanted me to spread my wings and fly high. It's a pity that he died early. His colleagues in the Zhenhun Division used their unique naming talents and just called "Fei" "waste". I work as a concierge in the Soul-Suppressing Department. Job Description: Janitor. Career achievement: Alive. Ideal in life: Retire peacefully. The biggest regret: The Lord of Hell is cheating on me. Call me a waste, I admit it. After all, the entire Soul-Suppressing Division and even the cats in the cafeteria have monster blood, and I can't even ride a horse. But I have a pair of eyes that are not quite right - I can see the true name of the ghost, the details of the demon, and the origin of the magic weapon. But there are many people with this ability in the Soul-Suppressing Department, so in a place like the Soul-Suppressing Department, I am still a waste. My life creed is very simple: if the sky falls, a tall man will hold it up, and I will be responsible for squatting. But I don't know from which day the sky stopped falling and started to fall on my head instead. First, I smashed down a strange case, and then smashed down a demon bell that had lived for hundreds of years. Finally, even the Lord of Hell personally assigned work to me. As a gatekeeper, I was stuffed with a lot of benefits, but there were huge troubles behind them. Benefits are imposed by the King of Hell, and troubles are imposed by the King of Hell. I wanted to return it but he wouldn't let me. This is the story of a waste who was forced to take up a job. Logically speaking, this should be a passionate and inspirational legend, but I really just want to retire.
