Shen Qinghe's father, Shen Qian, was the most outstanding engraving craftsman in Daliang Qintian Prison, and was in charge of the palace timekeeping and the construction of the armillary sphere. A bizarre case of celestial phenomena caused Shen Qian to be exiled to Lingnan for "the crime of deceiving the emperor." The Shen family was sealed off, and his mother died of fear, leaving only the sixteen-year-old Shen Qinghe and a semi-finished "Qian Ji Yi" that his father hid in the mezzanine of the stove.
Two years later, Shen Qinghe made a living anonymously as a young apprentice at "Qinghe Watch Shop", repairing clocks and selling sundials in the West Market in the south of Chang'an City. Her biggest obsession is to complete her father's unfinished Thousand Machine Instrument - a precision instrument that can simultaneously track the movement of the sun, moon and stars, and is the only evidence to overturn the case.
One thunderstorm night, a strange man, soaked all over and bleeding from his right ear, broke into the clock shop and passed out in front of a chiming clock she had just repaired. Shen Qinghe hid him in the backyard cellar and found that he was holding a fragment of a rain-soaked silk painting in his hand - the brushstrokes on the painting were exactly the same as the "green landscape" technique that was forbidden in the palace.
The man woke up and called himself "Chen An". He was deaf and unable to speak. But Shen Qinghe discovered that he was deaf in his right ear and his left hand was injured, but he could accurately point out the gear mesh deviation when she repaired the watch.
He is not deaf-mute. He just wouldn't talk.
The dark patterns on the fragment of the silk painting coincided with the patterns engraved on a missing gear of Qian Ji Yi.
Two people who kept their own secrets started a race against time in a clock shop.
Concept: The truly sophisticated mechanism is not in the gears, but in the human heart.
