Steam gears roared in the late Qing Dynasty, and mechas and swordsmanship danced together in troubled times! {Ling Yunxiao} was originally a low-level worker in the Ordnance Bureau, but unexpectedly awakened to the behind-the-scenes manipulation system - by hiding in the dark and changing the situation, you can unlock rewards such as mecha blueprints, ancient swordsmanship, and time retrieval. Faced with selfish colleagues who are stealing credit, villains from the fairy world who are pursued across borders, and yandere junior sisters who are paranoid and protective, he is both good and evil, pretending to be a pig and eating the tiger: he uses system manipulation to reverse the crisis, uses memory recovery to unlock magical powers from his past life, and uses his skill to rejuvenate and bind key connections. From repairing scrapped mechas to controlling the lifeblood of the Qing court's ordnance, from avoiding plots in the workplace to fighting against threats from the fairy world, as the gears of steampunk turn, Ling Yunxiao stirs up the wind and clouds with his behind-the-scenes hand. In the troubled times of the late Qing Dynasty, Ling Yunxiao will eventually find a counterattack path in which mechas and immortals coexist!
