Wake up and Enter the Ice Age!

Lin Bai woke up from the sleeping cabin and found that he had entered the Ice Age. He originally came from time travel, and with the high technology provided by the system, he quickly became a world giant. Although he had the skills, research would take time, so he fell into a deep sleep. Waiting to wake up again. "150 Years." Lin Bai looked at the time in the base and fell into silence. This was because there was not enough energy to forcefully wake him up. Checked the base situation, drones, helicopters, firearms... Everything is intact. Through drone observation, he finally discovered humans. The men wore tattered clothes and carried tattered tools. Too bad. The whole world seems to have regressed. Someone saw the drone and shouted excitedly. "Look, there's a bird, there's a bird." "Knock it down, knock it down." "..." Hearing this, Lin Bai's excitement disappeared instantly: "Tai! People from the island country!" "A pig, even a drone doesn't recognize it!" "Return the bird... The bird is your uncle!" This novel and its characters are purely fictitious.
