In the ancient town of Qingxi, Shen Qingheng, the abandoned daughter of the Shen family, was forced to sign a marriage contract: she would marry Gu Yanci, the young master of the Gu family, in exchange for the final shares of the Shen family's double-sided embroidery. On their wedding night, Gu Yanci coldly warned: "You are just a tool for me to clean up the family." The Shen family's cousin Shen Bitong publicly accused her of stealing the secret recipe for ancient jade carvings. Gu Yanci believed it and locked her up in the ancestral hall. Shen Qingheng bit her lip and did not cry - because her mobile APP automatically recorded the entire process, and the time stamp, recording, and monitoring backup generated a legal evidence chain with one click. What's even weirder is that every time the enemy's well-planned conspiracy always encounters a "coincidence": the fake account book hidden by Shen Bitong was picked up by a wild cat at her feet, and the Gu family's rival Zhou Heting's commercial spy was photographed by a surveillance camera blown down by a gust of wind. Shen Qingheng knew that this was not metaphysics, but the game-breaking intuition she had developed since childhood and the fatal "luck" brought by her koi physique. She began to forbear in collecting all the evidence: equity holding agreements, malicious short selling records, videos of stolen intangible cultural heritage recipes... Until the fourth volume, Gu Yanci found out the truth and begged her to stay with red eyes. Shen Qingheng took out twelve notarized evidence books and opened Article 9, Paragraph 3 of the contract: "The party who breaches the contract must compensate for all the property. Mr. Gu, do you want to talk about feelings first, or go to court first?"
