Prison King's Order

After thousands of years of training and three reincarnations, what secret does Tang Jingmo, as the yin and yang extraditer, have? A cold-blooded hunter, a kind brother, who travels between the Yin and Yang realms, he will eventually be the best among ten thousand people! I am the master of hell! (This is my first time writing a novel and I don't have enough life experience. Please forgive me if there are any questions, thank you!)
