In the tenth year of the apocalypse, warehouse manager Shen Yan was torn to pieces by zombies. When he opened his eyes, he became a clerk in Lin'an Prefecture of the Southern Song Dynasty who was about to starve to death. Before he was lucky enough to escape, a food shortage began in the city, refugees rioted outside the city, and the superior officials in the government forced him to collect "non-existent taxes." When he was desperate, he found that he had a warehouse in his mind, which was filled with compressed biscuits, antibiotics and hardware tools that no one wanted before the end of the world. He took out two packs of biscuits in exchange for a full meal, and used a Swiss Army knife to save the father of his daughter Wei Qingdai. When the news spread, Tu Bao, the leader of the Cao Gang, was eyeing his goods. The salt merchant Meng Xinghe wanted to dig out his secrets. Even the judge Xiao Jiusi asked him with a smile: Mr. Shen, which workshop did your biscuits come from? Shen Yan locked the last box of cans in the warehouse, raised his head and smiled: Sir, we have to change the way we negotiate this business.
