Lin Xiao, a modern young man, travels through the world of mixed martial arts and is bound to the "Write a Diary and Spoilers to Make You Stronger" system. Without knowing it, all his wanton eroticism, accurate spoilers, and sincere confessions are synchronized in real time to the eleven female protagonists including Huang Rong, Xiao Longnu, and Zhao Min. While he was letting himself go in his diary, the heroines were exchanging information, complaining about their husbands, and tacitly helping him pave the way to becoming an immortal through a "secret group chat" - this is a joyful legend of immortality where "everyone knows the secret, only the protagonist is serious about the strategy."
