Lin An was originally a top science and engineering master, but he was determined to serve the country through scientific research, but he was tragically killed in a car accident.
When he opened his eyes again, he became a poor scholar of the same name in the Yu Dynasty. His parents died and he grew up eating the food of hundreds of families.
Looking at the drafty hut and the bottomed rice vat, he decided to solve the problem of food and clothing first.
When a neighbor brought him coarse salt with a bitter taste, his eyes lit up: "Purification technology is the first pot of gold!"
When the snow-white salt appeared in the market, the whole county was shocked.
Lin An was counting the coins when he was suddenly blocked by a mysterious man at the entrance of the alley: "Young Master, I'm afraid I won't be able to survive more than three days with this method of making salt."
