Planting Potatoes in Another World

When the secret that eating can make you stronger falls upon the starving and freezing Cangyin Continent, the old order of power is about to collapse! Long Jin, a young man from Earth, is unexpectedly transported to the Cangyin Continent, where there are no high-yield crops, humans survive by hunting and gathering, and power is shackled by the annual sacrifice system, with the rare awakened ones monopolizing worldly authority. Accompanying him are only half a cart of potatoes mutated by temporal-spatial essence and a scrapped tricycle. Unbound by the world's annual sacrifice rules, he discovers that eating potatoes can endlessly temper his body. He reclaims wasteland, builds a potato industry chain, and enables displaced barbarian refugees to grow stronger through mere satiety without awakening. But the productivity revolution brought by potatoes shakes the rule of the awakened, and other Earth transmigrators with ulterior motives follow. Ambitious ones steal potato seeds to establish theocratic nations, while allies join hands to build new forces. The infinitely evolving Long Jin must fight against city-states and beasts, and also decide the future of human civilization. — Description from novelcodex.org
