Li Xun, a modern deliveryman, encountered a car accident while delivering food. When he woke up, he found that he had traveled to the middle of the Ming Dynasty and became a frontier soldier who was seriously injured and dying on the battlefield. At a critical moment, he bound a "god-level investment rebate system". As long as he "invests" in anyone or anything, he can get a hundred times, a thousand times or even ten thousand times the rebate. He invested a steamed bun in a hungry comrade, and received a bag of refined grains and an invulnerable inner armor as a rebate; he invested a piece of broken silver in a down-and-out Baihu official, and received in return the command authority of Baihu and a lost art of war. Relying on this golden finger, Li Xun rose step by step in the army, calmed down border troubles, and accumulated power. Then he entered the capital and invested in salt and iron, water transportation, weaving and other industries with modern business thinking, making him rich as a country. In the court, he dealt with the civil servant group, the noble forces and the royal guards. He used investment to win people's hearts, used rebates to see through loyalists and traitors, and finally supported the new king, wielding power in both the government and the public, becoming a legend of his generation.
