The world of cultivating immortals is the "Ninth Heaven Realm" - there are many sects, and the weak and the strong prey on each other. The heroine travels through the book and becomes the cannon fodder junior sister Su Qingyue of the same name. In the original book, she was killed by the villain "Ancient Demon Lord" Mo Yuan after only three episodes. Su Qingyue bound Mo Yuan as the "target" of the system - ostensibly she approached him to survive, but in fact, as they spent time together, she gradually saw the loneliness and tenderness behind Mo Yuan's "villain" mask. The two changed from a "system-bound cooperative relationship" to a two-way redemption.
