Yun Dandan transmigrates into a book, becoming the utterly unremarkable Seventh Elder of the sect where the male and female leads live. She only managed to become an elder because she lived long enough.
But the story's timeline is five hundred years after the ending. The chaos has long since ended, the great demon has been sealed away, and the male and female leads have already finished tormenting each other, made peace, and ascended together.
The world is peaceful, and all under heaven live in harmony.
Yun Dandan: So am I here to laze around?
One day, she fishes a naked, beautiful young man out of the sea.
He has the most pure and innocent eyes she has ever seen. Gazing at her, he asks, “Was it you who saved me?”
Yun Dandan: Damn! My heart's melting! It's melting!
Thinking the poor young man needs saving, Yun Dandan takes him back to her sect and gains a well-behaved, sensible disciple.
She doesn't expect the boy to be a cultivation prodigy. Three days of his cultivation are worth thirty years of hers. Her good disciple becomes the sect's darling, and the unremarkable Seventh Elder rises in status right along with him.
She takes the boy to cultivate and to undergo trials. They compete with the major sects. Wherever they go, they wipe everyone out...
Until one day, she sees the beautiful young man cruelly crush a sect master's heart. Blood streams from his hand as he looks at her with innocent eyes. “Master, why are you looking at me like that? I'm killing an evildoer!”
Yun Dandan: But he's been at the top of the cultivation world's Ten Most Virtuous People list for years...
All seven sects' treasures are destroyed, and the demon sealed away a thousand years ago breaks free.
The world falls into chaos. The sects join forces to fight back, and in the midst of battle, she sees that the demon's face above the clouds is exactly the same as the beautiful young man's.
The great demon gives her a shy smile. “Dandan, thank you for saving me all those years ago.”
Dandan, my foot! She's in a fix! Can someone tell her how her kind, well-behaved disciple turned into the great demon? With no male or female leads in this world, how is she supposed to deal with him? The unremarkable Seventh Elder is asking for help online! It's urgent!
Theme: Even a passing character has to work hard to save the world.
