Peak Prison Master

Seven years ago, Zhang Fan was framed and imprisoned in the world's most terrifying prison. In this prison, there is an international killer whose hands are stained with the blood of hundreds of people, a powerful high-ranking official named Houjue, a soldier king who is on the wrong path, a mysterious and treacherous successor of mystical arts, and a gold-touching captain who has burrowed into tombs all over the world... Seven years later, Zhang Fan became the only person to come out of this purgatory.
