My Fast Food Covers Ancient and Modern Times and Has Pampered Ten Dynasties!

Qin He discovered that his fast food restaurant could connect ancient and modern times and randomly welcome guests from ancient times! After eating, they always put down some copper coins or belongings to pay the bill. The copper coins alone are worth thousands of gold! From then on, Qin He owned all kinds of priceless treasures, and also had time-space collisions with emperors and princesses. The ancients had potatoes, sweet potatoes, corn and other foods and medicines. They no longer suffered from hunger and were afraid of disasters. They began to vigorously develop infrastructure and became the most powerful country in the world! Who knows, what the ancients want to buy is getting more and more outrageous... "Seller, can you sell me the food and grass I need for a month for my army of 100,000 people? I need it tomorrow because I have to destroy Goguryeo!" "Seller, I want Wei Huo to kill all across Mobei. Do you have the weapons for an army of 200,000 to sell?" "Shopkeeper, you have the elixir of immortality. I want to live forever and conquer all the wastelands!" The next day, when Ying Zheng brought the Da Qin treasure to the fast food restaurant, he found that there were not only medicines for treating diseases but also a map of the world on the table. "Hahaha, eh, it's all eh!"
