Su Wanying, the night shift girl at the funeral parlor, was picked up by a rotting corpse in the middle of the night when she knelt down and kowtowed, calling her 'ancestor'. She thought it was a nightmare until the forensic doctor Zhou Huaian handed over a yellowed genealogy. Mirror Girl stroked her hair every night in front of the morgue. A note from security guard Bai Wujiu said, 'Your grandma also cried like this.' She is not a mortal, she is the bloodline of the coffinkeeper that has been sealed for hundreds of years, and the entire funeral parlor is the last lock to suppress the Yin veins. When Nanny Chen lit the soul-inducing incense and Lu Zhao's silver needle pierced the back of her neck, Su Wanying finally understood - what she was kneeling on was not a ghost, but fate.
