Modern person Li Feng just won a lottery jackpot, and before he even had time to enjoy it, he traveled through time to become the peasant second son of Li Village in the Daliang Dynasty, squeezed like an old ox by his entire family. The original person is 35 years old, his wife worked herself to death, three children follow him in hunger and freezing, and his parents are extremely partial—the eldest son is sent to the town to be a carpenter, the third son exhausts all family savings to study for over twenty years without even passing the Tongshi exam, while only the second son has his sweat and blood sucked dry for half a lifetime. The start is hell: Li Feng is injured by a wild boar, and the old mother Li Wang Shi not only refuses to hire a doctor, but also chases after him with a broomstick beating him. At the critical moment, Li Feng binds with a "Survival System", able to identify natural supplies and directly cash them in, opening up his road of counterattack.
