From the Lord of a Ghost Town to the Richest Man in Daqian

In his previous life, he was an actuary in the bank's credit department. After his sudden death, he became the most useless illegitimate lord in Daqian. The territory is a ghost town that has been washed away by the plague and robbed by horse bandits. There are thirteen old and weak people on the account, and the food is not enough for half a month. He only had half a broken volume in his hand. Tiangong Book only gives craftsmanship, not money or food: sugar, spirits, colored glaze, grain seeds - if you want to survive, sell sugar first. Work points bamboo slips, advance payment contracts, bank notes. Others brought martial arts through time travel, but he brought a whole set of financial methods that Daqian didn't have. From a ghost town to becoming the richest man in the world, he made more and more money while living a thinner life - because the lord he replaced had long since died.
