Li Qi, the son of Li Xin, traveled back in time. He wanted to be a salted fish and make inventions, but he was blocked in the workshop by Ying Zheng, who visited privately incognito. A combination of "economic warfare + black technology" deception actually caused Zhao's food prices to collapse and the supply of ironware to be cut off within three months. Yingzheng Longyan was greatly pleased, and he was granted the title of Censor Zhongcheng, ranking him above the Nine Ministers. From then on, Li Qi used new steel, new species, and new ships to help the Qin Dynasty conquer the six countries, pacify the Japanese slaves, and cross the ocean. When the world was about to be unified, the First Emperor could not forget his two barrels of "medical alcohol". He asked for them again and again, but was rejected every time. The tug-of-war between "give or not" has become the most absurd and heartwarming daily routine of the emperor and his ministers in the empire.
