Engineer Daqian: Start by Rubbing Gunpowder with Your Hands

Zhou Zida, a graduate of the Department of Chemistry, never expected that he, who had just received his degree certificate, would travel through time and become the most miserable abandoned son of the Daqian Dynasty. Faced with the prince's sure-fire situation, cut off food and grass, and the cold assassin who followed him everywhere, the only weapons in his hand were the "Advanced Inorganic Chemistry" and "Industrial Refining Guide" in his mind. "There is no gun, no cannon, the chemical laboratory made it for me." So, in the northern border of Daqian, a series of miracles appeared that made the ancients doubt their lives: he could scrape "sky thunder" from the cracks in the wall, he could burn "artificial stone" from loess, and he could even use the most common grease to make "balsam" that made the powerful go crazy. The old emperor thought he was a lost dog, and the prince thought he was a soul killed by the sword. But when Zhou Zida, carrying the sour and rotten atmosphere of the laboratory, commanded the torrent of steel to approach the city, the whole world fell silent. "Zhou Zida, what kind of magic are you doing?" Zhou Zida pushed up his glasses without prescription (homemade) and smiled calmly: "Father, this is called chemical reaction. Now, I want to talk to you about what real 'power' is."
