Mu Zijin, a young woman who just wants to enjoy a peaceful retirement, transmigrates into a book. In the story, the original Mu Zijin gives up her position as a grand sect leader for love and elopes with a man, only to discover that she is merely a substitute.
Her man attracts the villains' hatred to help the heroine. At the climax, he even disguises her as the heroine and sets the villains against her. In the end, the villains kill her, then the heroine wipes them all out.
Knowing how the story goes, Zijin trembles with fear and decides to return to her immortal sect from the start, where she can enjoy her retirement and look after the little disciples the book barely mentions.
But when she gets back, she discovers that her disciples are all... world-destroying villains?
.
No one knows that the milk-sweet first disciple of Grand Sect Leader Mu is actually the Great King of the Underworld, who commands an army of spirits. When he sees his master return, he raises the seal of the Underworld King ahead of time. "Master, if other people have something, you should have it too." He summons his spirit army to snatch every magical treasure in the Three Realms.
Her quiet second disciple is the eldest disciple of an immortal family, undercover among them. When he sees his master return, he hefts a greatsword powerful enough to destroy the world. "Master, you should also have what other people don't." He destroys every secret realm in the Three Realms that people have coveted for ages.
Her adorable third disciple is the little crown prince who ran away from the Demon Realm. He returns to inherit the throne. "Master, they want to kill you. I can't let that happen." He slaughters the entire army sent by the heroine.
Her honest, steadfast fourth disciple is a great demon king pretending to be mute. When he sees his master return, he says, "Master, what right does that woman have to wear a face like yours and keep opposing you? I won't allow her to exist." He goes alone to kill the heroine and her army.
In the end, Mu Zijin has done nothing at all, yet her villainous disciples have already driven their hatred levels through the roof. The heroine flies into a rage and decides to destroy her and the villains ahead of schedule.
Mu Zijin, who transmigrated into a book just to retire: ...No, please, just listen to me...
We don't need any of these benefits. How about we retreat into the mountains and live in seclusion?
Her disciples immediately surround her. "Retreat into the mountains and live in seclusion: does that mean spending the rest of your life with us?"
[The substitute in her lover's eyes, the beloved master in her disciples' eyes]
[My master could never be a substitute. Your heroine is the real substitute, say the disciples]
[The gentle and beautiful, easygoing grand sect leader, and her disciples, who seem obedient but are actually full of schemes]
