Dongfang Lan, an orphan girl rescued on a snowy night, turned out to be the reincarnation of the Chaos Goddess Lan Ge. The secrets of the three thousand years of war between immortals and demons, the calculations of the Emperor of Heaven, and the obsession of the demon world were all revealed layer by layer due to her awakening. Carrying the power of both gods and demons, and bearing the weight of a century-old oath, she struggled to grow up in the cracks between immortals and demons. In the end, she awakened to the origin of chaos, and stood side by side with Xuanyuan Shao, the God of War who had been waiting for three thousand years. Using the peach tree as a warning, she guarded the balance of the three realms and composed a song of destiny that followed life and death.
