After Time Travel, I Created Civilization

Construction + Farming + Expansion + Unsystematic Original Text It's for entertainment only, please don't be too formal. An accident caused Qin Ming to travel through the wilderness era! Giant beasts are rampant here and dangers abound! Birds of prey roared past in the air, giant crocodiles stared at them in the water, and there were even powerful saber-toothed tigers and giant pythons more than ten meters long hidden in the jungle. Human beings have not yet reached the top of the food chain. They can only survive in the cracks in the territory of various ferocious beasts, facing the threat of death at any time... But all this changed completely because of Qin Ming's arrival! Modify bows and arrows, make pottery, raise livestock, smelt metal, teach planting, reclaim wasteland, create characters, issue currency... Climb the technology tree step by step, conquer the four directions and unify the mountains and rivers! That day, Qin Ming stood on the city he built with his own hands. Now that thousands of people were coming to court, he could finally proudly announce to the world: "After time travel, I created civilization!"
