In 2025 AD, quantum physicist Lin Mo traveled to the Tongquetai Underground Palace in the seventh year of Jian'an in an experimental accident, only to find that the scientific research bracelet he was wearing could analyze the Mohist mechanism. When he witnessed Zhuge Liang, who should have died of illness in Wuzhangyuan, using a magnetic storm coil to control a bronze machine beast to etch the "Book of Changes" star map, a two-thousand-year-old civilization defense war exploded.
Here, Zhang Fei's Zhangba Snake Spear is embedded with the resonance frequency device of "Nine Chapters of Arithmetic", Su Wan's arithmetic chip can interpret the binary last words in the eyes of corpses; the lost Xuanji Jade Heng is turned into a quantum chip, and Zhang Heng's seismometer actually contains a Klein bottle structure hidden inside. As Zhuge Liang shook his feather fan, the armored corpses of the Wei and Jin Dynasties emerged from the underground river, and the jade cong shining in his heart was the unfinished entropy reduction equation of Lin Mo's laboratory.
As the Youzhou Fire Well erupts and the quantum cloud appears in the First Emperor's Mausoleum, Lin Mo gradually uncovers the terrifying truth - Yinghuo Shouxin and Chibi Skyfire in history are all cracks in the closed loop of time and space. To prevent modern civilization from being turned into rust on bronze gears, he must collect seven civilization keys: from the Mohist optical forbidden technique to the curvature formula of "Zhou Bi Suan Jing", from the magnetic storm array of Cao Wei's Corpse Soldiers to the sonic weapon of Zeng Hou Yi's Chime Bell...
When the star map of the Jian'an period overlapped with the Orion Quantum Cloud, and when the armillary sphere activated by the Xuanji Yuheng began to swallow up the city of the 21st century, Lin Mo finally understood the last warning of the bracelet: the so-called "repairing history" is actually fighting with higher civilizations for the "tampered timeline" - and the first paradox to be erased is himself.
