Night shift security guard Chen Muba always lit cigarettes for the corpse in the early hours of the morning, while the entire library knelt down and held their breath. Forensic doctor Zhou Ye investigated secretly and found that each cigarette corresponded to an unsolved injustice. When Granny Hui handed over the first piece of yellow paper with blood on it, Lao Yan's antiseptic began to ooze black blood, and Heijiu's body trafficking truck crashed into the back door - it turned out that the funeral parlor was a living altar for the shady marriage ceremony. Chen Duba's silence is the last words of the deceased; Zhou Ye's scars are the tampered birth date. They must light the whole building before the next full moon and make the deceased kneel and speak.
