Mo Heng, a top student in the Department of Mechanical Engineering, was a small craftsman in Yingtian Mansion in the Northern Song Dynasty. When he opened his eyes, he saw a fire-smelling craftsman's workshop. Faced with the inefficient water drainage and fragile pig iron, the technology tree system in his mind quietly lit up. The improved water drain turned into a prototype of steam, which actually caused the craftsman to sneer: "If this thing can breathe on its own, I will swallow the iron slag alive!" Mo Heng smiled without saying a word, turned around and attracted the embroiderer Shen Yunjin - the precision of her fingertip embroidery was the key to the gear's leap. When desulfurized coal rises with blue flames in the blast furnace, the ancient method of "Tiangong Kaiwu" turns into molten steel flowing in his hands. When the assembly line of the movable type printing shop roared for the first time, the conservative official overturned the tea table: "Fantastic skills and ingenuity have violated the laws of my ancestors!" But Mo Heng pushed the reformed book of the craftsmen's guild to the emperor: "Your Majesty, the power of steam can carry giant boats and capsize boats. I am willing to use the 'Ministry of Industry and Commerce' to control this thunder." In the morning mist of Bianjing, the whistle of the first paddle-wheel official ship sounded, and the thousand-year-old feudal ice cracked and echoed crisply.
