Chen Mo, a PhD in agricultural economics from a prestigious university, wakes up after a plane crash in a primeval land where towering trees block out the sky. He unexpectedly gains a sign-in System, and the local tribe venerates him as a “divine messenger.” Determined to lead the tribe toward civilization with modern knowledge, he casually scatters hybrid rice seeds that make barren soil yield bountiful harvests, revolutionizes water storage with clay pots, improves poisonous fruit using botany, and builds a salt trade network with economic know-how. In just three months, he takes the tribe from hunger to abundance. He even uses chemical agents to exploit the “divine revelation” and undermine the tribe's worship of the giant totem tree. When the priests rebel, claiming he has “angered the gods,” he defeats them with homemade gunpowder and empowers his followers to establish a new order centered on “knowledge.” He introduces a calendar and sets up schools, but as he gets closer to the truth, strange things begin to emerge: near the heart of the giant tree, he hears a mechanical hum, and its sap contains traces of silicon... Is the founding of this primitive dynasty a triumph of knowledge, or a dreamlike illusion under observation???
