An accidental injury led to thirteen murder cases.
Princess Liu Ning of the Han Dynasty accidentally injured Dong Zhao, the grandson of the current imperial concubine, during a hunt for an anaconda demon. Because she was born psychic and had the power of the underworld in her body, the only way to save Dong Zhao's life was to collect the Thirteen Needles of the Ghost Gate.
After that, Liu Ning took Dong Zhao, who was seriously injured, and the guardians of the five attributes of metal, wood, water, fire, and earth, and went south together, working together to resolve the obsession and pain of the thirteen undead and fulfill their last wish.
