Sang Suining transmigrates into a xianxia novel as a cannon-fodder junior sister who won't survive past the third episode.
To escape the deadly fate of taking a tribulation for the heroine, she devotes herself to farming and opening a shop, but ends up attracting a cold master, a sword prodigy, a fox king, a demon lord, and a prince of the divine clan.
As the truth behind the Book of Fate comes to light, she joins forces with the original heroine to tear apart a sacrificial system that has lasted ten thousand years and reclaim the right to choose their own destinies for everyone written off as cannon fodder.
