When the thousand-year snow atop Mount Cangwu turns to bloody rain, the star patterns on the back of Su Yan, an apprentice at an apothecary, begin to burn. The fate of an ancient Star Official reborn, the whispers of demons from the Netherworld Abyss, and twenty-eight Heavenly Dipper seals crumbling one after another. From the Dark Water formed by the tears of merfolk in the South Sea to the map of the celestial stars hanging upside down atop Kunlun Ruins, the young people bearing the destinies of the Four Symbols gradually discover that restarting the Demon-Sealing Array requires more than divine artifacts. The souls of the star-born reincarnates must also be offered as sacrifices.
The Southern Bright Flame in the sleeve of the Azure Luan Daoist shines upon the vows engraved on the Three Lives Stone, while the cracks in the shell of the young lord Xuanming bear witness to three thousand years of waiting by the Black Tortoise Clan. Caught between the memories of the stars and his own humanity, Su Yan must make a choice that will shake the Three Realms: become Kui Wood Wolf, the Star Lord who watches over the celestial stars for eternity, or remain a mortal apothecary who would weep for all living beings.
