Zhao Zheng, a modern-day CEO, unexpectedly transmigrates into the body of a middle-aged widower during a famine. He inherits two gaunt future daughters-in-law, a family so poor they can barely make ends meet, and a former self who was beaten bloody by his own brother, who then cheated him out of his son's compensation money.
In this desperate situation, he binds himself to a multifunctional Trading System. Chopping wood and hunting can both earn him money, and the System's shop is stocked with everything from rice, flour, meat, and eggs to cotton clothes and medicine!
He protects his daughters-in-law and stands up to nasty relatives, drives off thugs trying to steal firewood and food, and secretly improves their meals with supplies from the System, nurturing his pale, underfed daughters-in-law into plump, healthy women.
He seizes opportunities of the era to build a business, chops wood and hunts to build up the family fortune, and digs a cellar to stash supplies. He keeps his wealth discreet and proceeds one steady step at a time.
