Borrowing Heroes

Tang Miao opened a bookstore, and her life was like a pool of stagnant water. Until late that night, he witnessed a woman's heart being ripped out. The murderer has no face, only a pair of gray eyes. Police say he is a suspect. But a weirdo named Zhou Yuanzhou let him go and said, "You have its mark on your body." Tang Miao didn't believe in monsters until the monster came to her door. To protect a girl he had never met, he shielded himself from the gray eyes. At that moment, an infinite library appeared in his mind. There is only one line of words on the bookshelf: "Which book would you like to borrow?"
