Modern girl Li Qianluo time-travels into a book, becoming the wicked supporting actress of a Mary Sue novel. The Prince Qi estate is entirely composed of cannon fodder with miserable ends. She binds with a going-crazy system; failing tasks results in being struck by five lightning bolts. While completing bizarre tasks, Li Qianluo wakes up her love-brained father and brothers, exposes the schemes of female lead Shen Suwan, reverses the family tragedy, prospers the declining Prince Qi estate, and lives as the pampered darling of everyone.
