Forensic: I Can See the Truth in the Folds of Time and Space

Forensic doctor Lin Yan has a secret - when the clock rings in Bell Tower Lane at three o'clock in the morning, he can see "folds of time and space": figures in raincoats, scalpels stained with blood, and pocket watches scented with locust flowers. These all revolve around what happened ten years ago: Master Lin Jianguo "committed suicide" and the scalpel was not found, leaving only an empty knife sheath with a locust flower petal inside. Later, the owner of the clock shop in Zhonglou Lane died with a fake pocket watch in his hand, with the word "city" engraved on the watch core. The clues are connected at once: Zhao Laosan, the murderer of the pocket watch case ten years ago, was released from prison early and always went to the watch shop at three o'clock in the morning; Zhang Lei, the owner's missing son, left a record that "there is a problem with the gears in the clock tower, and Uncle Gu refused to tell anyone"; Gu Mingcheng, the master's brother, repaired the clock tower and smelled of Sophora japonica. Lin Yan found the blood-stained hammer and dug out his master's diary - as soon as he saw "'Old Zhong' used infrasound waves to create hallucinations, he was responsible for the crime ten years ago", intern Su Xiao was kidnapped and spread the word "Old clock factory, with a brass bell key". There are always locust flower petals popping up in the knife sheath, the coordinate gear hidden in the copper bell, and the dark figure wearing a bell hat in the clock factory. Lin Yan knew that in order to reveal the truth about his master and save Su Xiao, he had to follow the "Folds of Time and Space" to find the gear box under the bell tower - which contained the true purpose of the "old clock".
