A forbidden love that spans thousands of years, a life and death game that subverts Yin and Yang.
Su Jin, a modern cultural relic restorer, accidentally touched an ancient mirror from the Tang Dynasty and was drawn into the underworld. She woke up on the banks of the Wangchuan River and became the target of public criticism in the underworld because of her contract with the "Yin Yang Mirror". The leader of the underworld, Mo Li, the master of the soul-wading division with mysterious clothes like ink and the sound of a piano that soothes the soul, insists on imprisoning her in Fengdu, only to find that she is the reincarnation of her lover Su'e who died thousands of years ago.
Wraiths in the underworld have gone berserk one after another, and Taoist artifacts from the Yangshi Temple have been mysteriously stolen. All clues point to the mysterious organization "Guiyi Alliance". In order to solve the dilemma, Su Jin used modern cultural relics knowledge to analyze the ancient books of the Yin Dynasty, and Mo Li used the Nascent Soul sword energy to suppress the reverse flow of the Wangchuan River. The two were forced to join hands and piece together the shocking truth from the fragments of the bronze mirror of the Tang Dynasty - the Yin-Yang Mirror was actually cast by Mo Li thousands of years ago to resurrect Su'e for violating the rules of heaven.
The shadow of the past life appears in the Forgotten River, and the destiny of this life is determined by the gaze of the hometown.
When Su Jin's blood seeps into the cracks in the Yin-Yang Mirror, and when Mo Li's strings cut through the lunar eclipse night, after thousands of years of obsession and protection, we finally face a fateful choice at the end of the underworld:
Should we fulfill the iron law of yin and yang and be separated forever, or should we burn all our cultivation to change our destiny once and for all?
