πI recommend the following two novels to you, both about prison: 1. "Born in the World of Film and Television"-This heavenly novel starts with the identity of a police spy. It contains many elements of prison, such as "Prison Storm","Infernal Affairs", etc. 2. "Goblins Must Die"-This fantasy novel began with the protagonist in a prison controlled by goblins. Although the subsequent plot was different from "Hero's Prison", it deeply explored the horror and limits of prison life. I hope you like my recommendation, Mwah ~π
