In the era of science and technology, Lin Yan, an omnipotent technology madman, was born in the wilderness period. The collision between primitive barbarism and future civilization. Bloody, ignorant intertwined. Lin Yan closed his eyes when he opened his eyes. Is this really a place where people can live? She wanted to live on her own Extinct, but as the human race at the bottom of the food chain, she can't stand being swallowed by fierce beasts. She has no choice but to be self-reliant. Lin Yan believes that technology can change everything, and the prosperity of the human race is not a dream. The big infrastructure starts from the life of the savages.
