Iron Masked Ghost Catcher

What is Hanyang City most famous for? It's two agents A crazy, sometimes sane, sometimes crazy, but deeply trusted by a local policeman. An iron-faced ghost with an iron face, hatred of evil and unknown origins, was captured by the iron-faced ghost who was considered a great hero by the local people. If you smell a stench on the street, it must be the smell of crazy police. If you see a flash of silver light in the middle of the night, it must be a ghost hunter punishing rape and eliminating evil. The world is collapsing, and the scenery outside the ivory tower has not been witnessed by any sentient beings, but they think it is a miracle from heaven.
