In ancient times, the Human Emperor, Zhao Ming, petitioned on behalf of the people and sacrificed himself to resist the divine realm. After Zhao Ming's fall, his beloved, Hun Dun Zhu, risked her life to save a wisp of his soul, setting up the cycle of reincarnation for eternity. In the distant future, Zhao Ming reincarnated as Xie Xue Chen, the leader of the Immortal Alliance, while Hun Dun Zhu became the Holy Maiden Mu Xuan Ling in the Dark Domain. The two finally reunited in the mortal realm but had forgotten their past, becoming adversaries in a "righteous versus evil" struggle. Mu Xuan Ling saved the heavily injured Xie Xue Chen in the Dark Domain and coerced him to travel together in gratitude for saving his life. Throughout their journey, the two went from harboring schemes against each other to fighting side by side, gradually letting go of their guard and developing feelings for each other. However, amidst the conspiracy to seize the divine artifact, the "Chaos Pearl," they found themselves in a life-and-death trial. Mu Xuan Ling sacrificed herself to save the world, and Xie Xue Chen defied fate to go back in time and rescue her. With the end of the eternal calamity, Xie Xue Chen's soul finally returned to Zhao Ming, but Zhao Ming's original form had become a demon god. Mu Xuan Ling used love to awaken the demon god, dispelling the catastrophe and bringing peace to the world.
