One century earlier, the immortal Tian Quan vanquished the Mirage Lord in a fierce clash, causing the Mirage Spirit to vanish from Cangshuo. Yet her soul fractured, and she forgot the duel.
Following that conflict, Tian Quan descended to the mortal realm to tend Cangshuo"s fields and took in an immortal sparrow named Li Xiao. The bird swiftly assumed a human shape, and Tian Quan was struck by how closely Li Xiao"s looks and manners mirrored her lost love Shao Weili. Born with a gift to recognize countless herbs, Li Xiao ventured out to heal the sick and aid villagers on Tian Quan"s behalf. When she sensed that Li Xiao had not returned for days, she journeyed to Luoyi Village in search of him. To her horror, every resident had perished and the Mirage Spirit re‑emerged.
Together, Tian Quan and Li Xiao confronted the Mirage, quelling the town"s peril. As Tian Quan recovered her fragmented memories, she realized a possible link among her departed lover Shao Weili, Li Xiao, and the Mirage she had slain. The revelation sparked a quest for truth, urging Tian Quan to uncover the hidden forces binding destiny, memory, and the realm beyond sight.
