Lin Xiao, a top occultist in the real world, accidentally entered a novel world full of supernatural and horror. In this book world shrouded in strange shadows, all rules are distorted, and Cthulhu-like terrifying creatures lurk in every dark corner, peering into the souls of intruders.
As soon as he traveled through time, Lin Xiao found himself at the scene of a strange death ceremony. The blood outlined indescribable symbols on the ground, and eerie murmurs came from all directions. With the profound knowledge accumulated in the real world, he quickly realized that it was all related to the Cthulhu evil god sealed in the book. And his arrival seems to have broken some ancient balance, causing the horror in the book world to gradually get out of control.
Lin Xiao has no heroine to accompany him, and he travels alone in the crisis-ridden book world. From the cursed ancient library to the catacombs hiding endless secrets, each adventure brings him one step closer to the truth, but also plunges him deeper into the whirlpool of madness. Not only does he have to deal with the endless supernatural events in the book, but he also has to prevent himself from being eroded by the book world and becoming a puppet of Cthulhu. In the game with the unknown horror, can Lin Xiao uncover the truth behind the book world and find a way to return to reality, or will he eventually be swallowed by this boundless darkness and become another victim of the book world...
