Da Qin: I Really Just Want to Open a Wine Shop

In the eighth year of the Qin Dynasty, Lu Chuan came back through time with a fishing system. All he could catch were tomatoes, potatoes and other vegetables, so he had to open a wine shop in Xianyang City first. While getting familiar with life in the Qin Dynasty, he was waiting for the exchange function in a year to exchange for the Yellow Emperor's Internal Medicine, the elixir of life. A customer who calls himself Mr. Shang often comes to the wine shop and spends a lot of money. After seeing all kinds of ancient things in the wine shop, he will always be in disbelief. "This roasted sweet potato is not only delicious, but the yield per acre is at least 1,000 kilograms?" "This cement can not only build roads, but also the Great Wall?" "This *paper can not only wipe hands, but can also replace bamboo slips?" … A few months later, Lu Chuan finally obtained the elixir of life and the Huangdi Neijing, and when he was about to enter the court, Mr. Shang suddenly told Lu Chuan: "Shopkeeper, I have shown my cards. In fact, I am Ying Zheng." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
