Gu Ning transmigrates into the novel she wrote and faces the fate of a cannon-fodder character from the start: she is about to be sacrificed and die.
The plot is completely out of control, and the world is on the verge of collapse.
The novel's beloved female lead is reborn and turns evil, abandoning love to focus on overthrowing the emperor's dynasty.
The demon realm's Tushan clan wreaks havoc in the mortal world, while its vengeful fox princess sneaks into the palace. A fugitive prince assumes a new identity and enters the imperial selection to plot his revenge.
Gu Ning binds herself to a Plot Maintenance System and gains access to a system shop where anything can be bought, using it to secure a slim chance of survival for the two of them.
She anonymously spends a vast number of points to give the female lead weapons and strategies, paving the way for the leads to survive, all in the hope of keeping the main storyline intact and returning home.
But the female lead grows increasingly suspicious of her.
As cannon fodder, Gu Ning can only struggle to stay alive amid the competing factions and do everything she can to turn the collapsing situation around.
