Two ghosts who have been with each other for thousands of years and come to modern times. Hei Wuchang, with a cropped head and a black suit like a penis; Bai Wuchang, a refreshing big boy in a sweatshirt and baseball cap. His immediate boss is Lord Bao Zheng, the King of Hell in the fifth palace, who usually goes up to catch ghosts and drinks soup with Sister Meng. I'm catching you, and you're here too.
