After being transformed into a little cannon fodder in the book who is doomed to die tragically, Su Qingyan has only one creed in life: stay away from the male and female protagonists, concentrate on practicing, and run away as soon as possible to ensure safety. But after all, she couldn't escape the fetters of the plot, and accidentally broke into the world of the villain Xie Wujin. Xie Wujin, the most mysterious being in the three realms, with unfathomable cultivation and cruel and bloodthirsty temperament, made an exception for Su Qingyan - he found spiritual materials and practiced skills for her, defeated powerful enemies for her, protected her, and gave her all his paranoia and tenderness. At first, Su Qingyan avoided this sudden preference and just wanted to escape; but gradually, she saw the fragility and affection under his brutal appearance, and discovered that she was no ordinary cannon fodder, but the last saint of the ancient Sioux tribe, tasked with guarding the Chaos Jade and sealing the ancient demon. In order to protect the people around her and uncover the truth behind the annihilation of the Su clan, Su Qingyan put aside her desire to run away and joined hands with Xie Wujin to travel across the three realms to find Chaos Jade fragments and decipher the ancient secrets. From an inconspicuous little monk, she counterattacked and grew up, and eventually, side by side with Xie Wujin, she became the co-lord and noble lady of the three realms, protecting the peace of the three realms.
