Goods Flow Between Worlds, and I Control the Wealth of Both

[Travel Between Past and Present + Turbulent Times and Famine + Ancient-Era Farming + Conquest of the World + Multiple Heroines] A miraculous pendant allows its owner to travel back and forth between ancient and modern times. After his younger brother schemes against him, Yang Changgen buys a cartload of grain and accidentally transmigrates to ancient times with both the cart and its cargo. The county magistrate, who looks exactly like him, happens to be fleeing with the public funds when Yang Changgen accidentally kills him. Forced to take his place, Yang becomes the magistrate of An County. In an era of constant famine when people everywhere are going hungry, Yang Changgen uses his grain and his ability to travel back and forth to the modern world to make sure everyone has enough to eat. At first, all he wants is to trade goods between the two worlds and become a carefree tycoon. But after he feeds the people so well, countless others flock to join him. Starting with a tiny county, they fight foreign invaders and fend off bandits. Their ranks grow from a few hundred people to an army of a million, and in the end, they rise to dominate a region and claim the realm.
