Yunyang, the lotus seed fairy in the heaven, broke the glazed lamp of the emperor of heaven by mistake and was demoted to the soul-breaking cliff in the demon world by thunder. When she was about to die, she awakened the barrage system of the three realms and was bound to the ultimate mission - to conquer the fallen immortal demon Lord Yanbai. Yanbai was once the glory of the immortal world, but he fell into the devil inexplicably a thousand years ago. He had a cold and solitary temperament and was decisive in killing. However, he had a fate that involved Yun Yang for three lifetimes. The two have lost their memories in this life and do not know each other.
Under the "strategic guidance" of the barrage, Yun Yang was forced to activate the "White Lotus" survival mode, pretending to be weak, crying, and clinging to the demon king's lap. From the first meeting in Duanhun Cliff to the day and night in the Demon Palace, she relied on barrage to resolve the crisis time and time again, which also made Yanbai's frozen heart ripple. The ink rope jade pendant on his wrist always shimmered when he was close to her, and the fragments of his past life quietly revived.
The pursuit of heavenly soldiers, the conspiracy of traitors in the demonic world, and the shocking truth behind the fate came one after another. Yun Yang, who pretended to be coquettish, moved his true heart, and the cold-faced demon also showed his gentle undertones. When the memory is unblocked, the love, hatred, anger and obsession from thousands of years ago surge forward. The two work together to fight against the obstacles of the immortal and demonic realms. In the end, Yun Yang gives up the opportunity to return to the heaven. Yanbai is willing to curb her demonic nature for her and use the body of a fallen immortal to keep her safe for the rest of her life. The barrage of the three realms watches this sweet and sad fateful love.
