In the autumn of the seventeenth year of Jingtai, the Yunbrocade Weaving Bureau of Jiangning Prefecture was brutally massacred. Pan Mingyuan's family and thirty-seven members of the family were not spared from the weaving. Only a batch of royal brocade patterns disappeared. The case remained dusty for twenty-two years and became an unsolved case that no one dared to touch. Twenty-two years later, Detective Shen Jingran took over the task force and discovered clues in the yellowed files - at the time of the incident, Pan Yaqing, the only daughter of the Pan family, was supposed to be resting in Ciyun Temple outside the city, but she was actually hiding in the locked west wing of the Weaving Bureau. The records of this empty room in the files were actually blank.
Late at night, Pan Yaqing suddenly visited and revealed more shocking secrets: on the night of the incident, she heard the sound of three brocade looms operating in the workshop, and that was the moment when the massacre occurred; before the incident, her father Pan Mingyuan urgently taught her the centuries-old "rewind weaving" and asked her to copy a mysterious pattern, saying that if something happened to her, she must pass on the weaving method. What's even weirder is that what the "Fupan Weaving" weaves is not a brocade pattern, but a "game" that can deduce the truth, and Pan Mingyuan has already predicted his own death.
Shen Jingran held the fragment of Yun brocade brought by Pan Yaqing, looked at the mysterious symbols on it, and finally realized that this was not an isolated case of massacre - a hundred years ago, the family of an old craftsman who taught "Fupanweaving" was also brutally massacred, using the same method. When the two tried to track down the truth, they discovered the corpse of an old tailor in the old warehouse area in the west of the city. Next to the corpse, a brocade loom was operating strangely, echoing the sound of the loom from twenty-two years ago.
