Zhen Bai Qian and Zhen Ye Hua fell in love. Zhen Bai Qian reincarnated as Bai Qian to endure the trials of the gods, while Zhen Ye Hua split his soul into three to find her: Zhe Yan, Mo Yuan, and Ye Hua. After three lifetimes, Bai Qian and Ye Hua finally fell in love, but Zhen Bai Qian's trial required her to live ten lifetimes. Bai Qian was reborn in the 21st century as Qian Xue, with no memories. Ye Hua made a wager with the gods, betting on the moment Bai Qian's heart would be moved. What he didn't know was that he himself was the god. Because Ye Hua made the wager, Qian Xue gained a System, lived for 21 years, and then transmigrated into Bai Qian. Ye Hua searched another world for Bai Qian for 2,021 years, but couldn't bear the poison of longing and drank the water of forgetfulness. Bai Qian then lost sight of Ye Hua's true feelings and thought, "This Bai Qian isn't that Bai Qian," not knowing that Bai Qian was herself. But the story of Qian Xue and Ye Hua, who drank the water of forgetfulness, was only just beginning!
