In Bianliang of the Northern Song Dynasty, mechanical gears burst out with bloody stars. Shen Tan of Dali Temple and the prodigy Zhong Ji are involved in a battle between technology and history.
The water-carrying ceremonial platform, the life-threatening piano strings, and the condensed glass mirror—a series of strange cases are both technological traps and cold evidence: fragments of cold-forged armor, ashes of cinnabar plums, and bloody chronicles, silently telling the story of Yuanyou's party struggle, the bloody battle of Pingxia City, and the hatred of Hehuang.
Shen Tan relied on his father's instincts, while Zhong Ji relied on technology to stay vigilant and fight against the huge power: secret arrows in the court, murderous intentions under the cover of pivot wheels, tattooed war trumpets, blood and tears without word monuments... Law and technology have become battlefields.
The murderer isn't the only one they're after. The error of the water transport instrument, the deviation of the magnetic needle... Every precise measurement pricks the scars of history. Conquests, party strife, and exile are all condensed in the remains of bronze figures, blood-stained tattoos, and worn movable type.
In the cold light of the escapement and the rotation of the god's arm bow, they tore open the Tokyo brocade and deciphered the code engraved in blood, tears and metal - at the intersection of the gears, under the grinding of history, can the bloody truth illuminate the abyss?
