Yunmeng Twelve Monuments

Li Xian was a Ph. D. In mechanics, but accidentally traveled to the Wei, Jin, Southern and Northern Dynasties and became a minor official named Xie Fei. He has no ambitions and only has one thing on his mind: to return to modern times and have his daughter. But in these troubled times, people can't live in peace. The tyrant Shi Hu insists on sacrificing him to the river, the prince wants to steal his brain for research and development, and those powerful generals also want to use him to practice boxing every day. Li Xian was anxious: I don't know martial arts, can I just get beaten? No! He just flipped up the table and started doing it - while others had been practicing martial arts for ten years, he secretly rubbed the "bronze repeating sleeve arrows" in the house; while others were riding horses to kill people, he made a "gear repeating ballista". Springs, ratchets, differentials... These later gadgets were forcefully inserted into this cold weapon era. This is called dimensionality reduction strike! Civil officials scolded him for being evil? He shot an arrow into the copper coin's eye a hundred meters away, and the other party shut up on the spot. The general laughed at him for not being able to restrain a chicken? He planted a circle of "land mines" that exploded so that the other party didn't even recognize his own mother. From a small official who just wanted to survive to the powerful "Xie Gong", he just relied on his black technology to turn the entire era upside down. In a sentence: Who says science students can't be gods of war? I can still use a wrench and a spring to become a god in these troubled times!
