In the capital of the Yuan Dynasty, there was a mixture of Chinese and foreign people, and the law was first established. Ayim Turan, the leader of the Uighur puppet theater, possesses the ancestral secret technique of "The Wooden Man Sutra", which allows puppets to reproduce the secrets of the joints of living people. A complicated and confusing case of collaborating with the enemy brought her into the sight of Zhang Chengbi, the censor. When the fog of power concealed the truth, Ayimu used the exquisite "puppet forensic" technique to hide a dripping sundial in the puppet cavity, move the time scale in a silent place, falsify key testimony, and shock the court. Her skill is not one person with many faces, but a dance of levers performed by everyone together. Each step is controlled by the iron law of physics, but it is therefore extremely solid. From the stage to the court, from the flying sawdust to the scent of ink in the laws and regulations, Ayimu and Zhang Chengbi, together with the skilled officials of various ethnic groups, used cold organs and a fiery truth-seeking heart in the questioning and collision to jointly promote the revision of the "Dayuan Tongzhi", engrave "mechanical evidence collection" into the imperial code, and compose a legend of judicial progress that integrates the wisdom of multiple ethnic groups. Technology is justice, and ingenuity solves puzzles.
