Jinling Yunjin Museum, the weaver died in front of the loom, his hands were hung up by silk threads, and the weaving shuttle was stuck in his chest.
A note was left at the scene: "If you can't make a match in seven days, the Weaver Girl will pay with her life."
The police were helpless, and Shen Moyan from the Folklore Research Institute was invited to break the situation.
He rummaged through ancient books and read a message from the lost "Yunjin Knot" - this was not a murder, but a sacrifice. Some people are using ancient folk taboos to set up a trap and turn every intangible cultural heritage into a "rules game."
A second body appears, and a third person has entered the game.
The murderer watched everything in the dark and said to Shen Moyan: "In the next round, you will be the 'weaver'."
Shen Moyan closed the notes left by his grandfather and sneered:
"Rules are dead, people are alive. But if you want to trap me with rules - you'd better ask first who made these rules."
