"The Border of a Poor Family" tells the story of a modern young man, Gu Heng, who travels to a poor family in Daliang. When he wakes up, he is faced with a dead end of a leaky thatched house, a sick mother with no medicine, an elder brother who will be dragged away by the corvee, and a powerful family member who has usurped the land. He has no system, and no magical artifact that can crush the times out of thin air. He can only rely on account books, arithmetic, knowledge and a little ruthlessness. Starting from saving the lives of his family, he gradually runs a bean mill, enters the county school, becomes an official in the imperial examination, and gets involved in land clearing, disaster relief, old salt and grain cases, and court party disputes.
From a poor family in Qingzhou to the Golden Palace, from a lonely city in Bianzhou to becoming a prince and becoming a prime minister, Gu Heng understood through the choices of life, death and power: it is not difficult for a person to climb high, but what is difficult is that after climbing high, he still remembers the dirt road he came from. Faced with the constraints of aristocratic families, the constraints of old ministers, the suspicion of the new emperor, and the invasion from the north and the south, what he has to do is not only to change his own destiny, but also to leave a path that is feasible and feasible for the world's poorer families, border people and newcomers, and that will not be easily blocked by the powerful.
