Jiang Zhijing, the little princess of the Demon Clan, lives by one rule: She'll take out whoever she wants. Everyone is equal.
When trouble breaks out at the border, she goes out to clear her head and meets two people:
A young lord of the Yao Clan, Yun He, pretends to be weak to get close to her. She sees through him: "Do you think I'm stupid?"
A prince of the Human Clan, Chen Xu, gives her a dagger. She asks, "Are you two competing? Then let me make a list."
She thought she was just going out for fun, but ends up caught in the power struggles of the three clans, ancient seals, and a fallen immortal's resurrection.
The fallen immortal tries to possess her, but the erratic thoughts in her mind leave him dizzy. "What kind of nonsensical mess is going on in your head?!"
Negotiations between the three clans are about to collapse. She draws a chart full of circles and arrows: "Follow this, I've worked it out. Everyone can make thirty percent more."
The bigwigs study it for three days. "...All right, then."
Her second brother wants to beat up Yun He. She says, "Do it! I bet you'll win. The stakes are three favors he owes me."
Her eldest sister is forced to inherit the title of Demon Venerable. She says, "Sis, want me to draw you an escape plan?"
At last, her parents run away, leaving a letter: "Kids, we're going out to have fun. The title of Demon Venerable goes to Chujing. Do a good job!"
