一天挣二三十零花钱的游戏

简介：To obtain salt, salt merchants must first transport grain to the frontier fortress. The purpose of this policy is to encourage merchants to transport grain to the border and enrich border military grain reserves. Transporting grain is not profitable, or even losing money. The only way to make money is in the salt industry. When it comes and goes, there is grain at the border and merchants make profits.
