Lu Mingyuan travels through the cold winter of 1965. At the beginning, his father has just died, the best neighbor is pressing for debt, and the family has been without food for three days. At a critical moment, he awakens the double-travel system: modern time stands still, and he can carry unlimited supplies. He used modern rice to save his whole family, used penicillin to save his younger brother, and built the first two-story building in the village with red bricks and cement. While others were so hungry that they gnawed tree bark, he stewed meat with white rice; while others fought over briquettes, he ate ice cream with the heater on in his room. From being a clerk in the street office to being in charge of the government, he used modern knowledge to reduce dimensionality and carry out construction, set up factories, collect antiques, and lead the whole village to become rich. In this life, he wants to change his destiny and let his family live a good life!
