Datang Pinduoduo, the Starting Reward Is the Gunpowder Formula

In Chang'an City, Tang Tianjun, the owner of Datang's single-order shop, welcomed his first single-order customers, Lao Li and Lao Fang. Lao Li: "Shopkeeper, this sweet potato tastes great. Why is such a rare item only sold for ten cents, and more than two people have to share the order." Lao Fang: "I feel strange too, but after trying it, I am extremely satisfied. Your Majesty... Lao Li, let's make an order?" After listening to Lao Fang's suggestion, Lao Li and Lao Fang each chipped in with five cents to buy a sweet potato. Tang Tianjun smiled slightly: "A rare thing? It doesn't matter whether it's money or not. Anyway, I had someone cultivate this thing on 600 acres, and the yield per acre is 6,000 to 7,000 catties..." Ding!
