Lin Mo, a modern office worker, accidentally travels to the primitive Stone Age. Right after landing, he is targeted as prey by the tribe. In a critical moment, he binds to an upgrade system—only when the tribe reaches the civilized level can he return to modern times. To survive, he teaches the tribe to make fire with flint using modern knowledge, wins the fire-stone battle and becomes famous, then is worshiped as the high priest. Later, he uses penicillin to treat wounds and extracts sea salt to improve diet, subverting the primitive survival mode and uniting the whole tribe. When the tribe thrives, the system sends a sudden warning: neighboring tribes are invading. Can he protect the tribe and complete the upgrade?
