Remembering a Great Disaster in the Park in 2345

In the year 2345, the number of humans on the earth has decreased sharply. As surface temperatures continue to rise, humans have taken refuge in underground shelters. The earth's resources are scarce, but the originally docile animals have begun to go crazy and attack humans on a large scale. People consciously formed a suicide squad to explore the ground, and actually discovered a forest in the vast desert. They thought it was salvation, but they didn't expect it to lead them into a more dangerous situation. This novel and its characters are purely fictitious.
