Lin Mo, a modern mechanical engineer, traveled through the late Hongwu era of the Ming Dynasty and became the orphan of a down-and-out craftsman who was convicted of "explicit skills". In order to change the humble fate of craftsmen, he relied on modern technology to improve firearms and build water conservancy, but he was involved in the whirlpool of imperial power change.
Faced with Zhu Yunwen's suspicion, Zhu Di's solicitation, and the encirclement and suppression of the civil servants in the court, he held "Tiangong Kaiwu" in his left hand and a flintlock gun in his right hand, carving out a bloody path of "rejuvenating the country through craftsmanship" in troubled times.
