I Transmigrate into a Book on Schedule Every Night

[Blurb] Si Yi transmigrated into a book. Every night at ten o'clock, he would be transported into an ongoing superpower novel. After the day's updated chapter had played out, he would return to his own world. Since he entered the book in his own body, with no original character to take over, Si Yi wasn't forced to follow the plot and was immune to the powers of every character in the book. He was always perfectly happy to be a bystander, watching the story unfold from the front row. Until one day, he saved someone on a whim, only to discover that the man was Ning Qian, the badly injured final boss of the novel. - Si Yi didn't want to get dragged into the plot, so he came up with a plan to escape from Ning Qian. The plan was thorough, and he successfully got away. But he was soon found again. Then Ning Qian had his way with him. Si Yi: TAT [Reader's guide] 1. Ning Qian is the top, Si Yi is the bottom. 2.
