New Era Survival Guide

In a strange thunderstorm and purple mist, geological surveyor Li Zhixing fell into the Eocene wasteland 40 million years ago. There are no humans or civilization here, only lush ancient forests and primitive beasts. He has become the only civilized person in this world. With only a set of outdoor equipment and offline AI, he fought against scorching heat, drought, floods, poisonous insects and ferocious beasts, and survived endless loneliness. In the desperate situation, a palm-sized prehistoric dusky dog ​​accompanies him. As the years pass by and the four seasons reincarnate, he struggles to survive and quietly waits for the rift in time and space that occurs once in several years. He faces the ultimate choice between returning home and staying behind.
