To break through the limits of his cultivation, Xiao Qingyuan, the Immortal Lord Lingxiao, must descend to the mortal realm and undergo the three trials of love, life, and death. He seals away his immortal senses and powers, taking on the identity of the Regent Prince of the Great Jing Dynasty, a man rumored to be cruel and sinister, with a secret ailment. Xu Qingnian, a young immortal from the Jade Pool who has been secretly in love with him for a thousand years, defies the celestial laws and follows him into the mortal realm. A celestial curse seals away her memories, and she becomes an orphan.
Terrified of the Regent Prince, Yao Zhiqing, the legitimate daughter of the Yao family, tricks the amnesiac Xu Qingnian into taking her place as his bride. As they live together in the mortal realm, Xiao Qingyuan is moved by Xu Qingnian’s gentle and guileless nature. His hard exterior melts, and the two fall deeply in love. The Immortal Emperor, Mo Bai, accidentally descends to the mortal realm and loses his memory, becoming a white snake. Xu Qingnian saves him, and he falls for her. He watches over her in silence, but when he sees that her heart belongs to Xiao Qingyuan, he sadly sets off to travel the world.
Consumed by jealousy, Yao Zhiqing frames Xu Qingnian, accusing her of having an affair with Mo Bai, and exposes the truth about the substitute marriage. Suspicion overwhelms Xiao Qingyuan. Though he loves Xu Qingnian deeply, he refuses to let her go, imprisoning her and pretending to grow close to Yao Zhiqing to provoke her. Meanwhile, Yao Zhiqing secretly mistreats Xu Qingnian and hires assassins to kill her. Xu Qingnian breaks her leg and loses her sight while fleeing.
Mo Bai returns and is enraged by her condition, determined to take her away. Along the way, Xiao Qingyuan unexpectedly regains his immortal powers and learns of all the schemes. Wracked with remorse, he plans to punish Yao Zhiqing severely and make amends. As Mo Bai flees with Xu Qingnian, assassins corner them on a cliff. They fall to their deaths together.
Xu Qingnian’s soul returns to the celestial realm, and her memories come back. The suffering she endured in the mortal realm has erased all her love, and she resolves to withdraw from the world. Xiao Qingyuan returns to the heavens and begs her to take him back. He uses an illusion to show her the whole truth, but her heart has turned to ashes, and nothing can stir it. Mo Bai also returns to the celestial realm and lets go of his obsession, staying by her side in silence until he finally moves her heart. The two remain together in the celestial realm, while Xiao Qingyuan is left alone with his regrets, doomed to eternal solitude.
