After transmigrating to the famine year of 1959, Su Bai finds himself a pitiful five-year-old who can't get enough to eat or wear!
His parents are frail, his older sister is pale and sickly, and the whole family is on the verge of giving out.
Just as he despairs of the future, a stroke of luck arrives from the heavens: his portable-space Exchange System activates!
Coarse grains, white flour, eggs, fatty meat, brown sugar, and cotton cloth are all available for exchange!
While others eat watery wild-vegetable gruel, his family has solid food at every meal and a little meat every few days!
He keeps his secret identity hidden, grows quietly, and secretly stocks up on food to protect his family.
He leads the whole family to eat well and dress warmly, and their lives grow brighter by the day!
So what if it's a famine year? With the System on his side, his family will enjoy peace year after year, with plenty of good food and drink!
