Every rainy night, Xie Ran would pass by an ancient library by chance. Until that night, he pushed open the door, and a book that felt like human skin opened automatically in his hand [Key soul detected: No. S-00—Snake Spirit Cyril. Welcome back] The flow of time in this library is strange. No matter how long you struggle in it, the reality only lasts three hours. The only way to survive here is to "read" and understand the extreme pain contained in each copy, redeem points, and exchange for life.
