I recommend "Demon Survival Game" and "Survival in a Strange World: Fear Everywhere" to you. They are both horror survival novels. The former told the story of the different demon identities and survival challenges of the people trapped on the mysterious island, while the latter was the story of the game players crossing into the strange and terrifying building world to survive. Both books were infinite works, with a continuous horror atmosphere and constantly evolving survival challenges, suitable for readers who loved horror elements and suspense reasoning. I hope you like my recommendation. Muah ~
