In 2045, the once prosperous world has changed beyond recognition. Chain disasters caused by global climate change are sweeping across every inch of the land like a raging tide. Human civilization was instantly set back a hundred years in this catastrophe. The city was reduced to ruins. Only the crumbling remains of the former high-rise buildings were left, whimpering in pain in the strong wind. The alien creatures are rampant in this desolate land. They are weird in shape and exude a disgusting aura. Every time they scream, they seem to declare their dominance over the world. Extreme environments follow us everywhere. The scorching sun scorches the earth, causing it to dry out. The cracks are like hideous wounds on the earth. When heavy rain pours down, it is mixed with corrosive acid rain, and everything is eroded wherever it goes.
