Su Qingyuan, the daughter-in-law of Dali Temple, possesses the secret ability of "reading memory" - touching an object can see fragments related to it. In order to avoid disaster, she hid her abilities for many years and only secretly helped her father solve small cases. However, due to the "serial murder case of the embroidered lady" in the capital, she unexpectedly got entangled with the commander of the Jin Yiwei Lu Xun, who was known as the "Living King of Hell".
She used the silk handkerchief Wu Yi to get a glimpse of the key to the murder, and he used ruthless means to track down the truth. The two went from suspicion to alliance, and worked together to uncover the East Palace conspiracy behind the embroidery workshop. Since then, the case of people being swallowed by antiques in the ghost market, the mystery of the assassination of the third prince, and the unjust case of extermination of the family in the Marquis of Jing'an Mansion have emerged one after another, and the undercurrent of the imperial court's heir apparent has engulfed them.
Su Qingyuan uses the memory of things as a blade, Lu Xun uses power as a shield, and with the help of young Amo, they work step by step amidst the shenanigans and conspiracies. They not only uncover the prince's ambition to usurp power, but also gradually develop feelings for each other in life and death. In the end, after the dust settled, the two people refused to be rewarded by the court, traveled around the world with their "notes of strange objects", and used their abilities to protect the peace of the place. They opened a physical evidence consultation shop in the south of the Yangtze River, and performed a legend of "looking at the world with their hands in hand".
