Traveling Through Hongwu, I Saved My Life by Opening a Convenience Store

On the execution ground of the Kongyin Case, Shen Chuan spent the last three minutes telling Zhu Yuanzhang three questions: the curve model of depreciation of treasure banknotes, the efficiency black hole of Taicang turnover, and the formula of military expenditure in border towns. Save someone under the knife. A month later, "Hongwu Convenience" opened on the south bank of Qingshui Bridge in Beijing. Salt, sugar, oil and vinegar are clearly marked with prices; firewood, rice, sauce and tea are packed in full scales. A white and gray wall is covered with posters from the market asking for purchases, hiring workers, and looking for people. Shen Chuan just wants to survive and make some money on the way. But he did not expect that: the "information wall" would become a channel for early warning of famine; the "table accounting method" he designed would be secretly tried by the Ministry of Revenue; and the "tree diagram of three water transport strategies" would become the draft for the Ministry of Works to ease blockages. Zhu Yuanzhang read the secret report in the Palace of Qianqing, and tapped the red pen: "This son is like a knife, it can scrape bones and cure poison. It can also... Hurt my hand." Shen Chuan stood behind the counter, weighing the salt for his old man and calculating silently. He didn't know that his small shop, which just wanted to save his life, had become Ming Dynasty's most special intelligence station, and he himself was being pushed into a fatal game about efficiency and control, data and imperial power.
