Earth Tour Survival Place

Humans have survived underground for nearly 500 years. The reason is that people in the past were afraid of the terrifying creatures that suddenly appeared on the earth. They had faster speeds, harder bodies, more powerful attack methods, and hunted other creatures for food. After three years of resistance, humans ran out of ammunition and decided to invest heavily in digging 200 meters underground to become a new stronghold. However, because the living conditions underground cannot support people's lives, an above-ground team is established. Every year, 350 people are selected from every city around the world to plant food the next fall and then recover the food. And carry other necessities. However, another type of lifestyle that was almost perfect entered a new era in AD 2621. Humanity vowed to return to the surface and defeat those monsters. But is what stands in front of them monsters or humans?
