I'm Really No Savior

"In 2122, due to the intensification of mankind's use of the earth's resources, the war broke out. At this time, due to the intensification of nuclear war and radiation pollution on the surface civilization, behemoths that were impossible to appear in human cognition appeared. Under the control of the earth's self-protection mechanism or Gaia consciousness, the number of humans decreased drastically in just one day. This disaster started by humans was like opening Pandora's box. There were only 500 people left in this sudden disaster. Wouldn't it be easier for me to accept it than your gallbladder cancer?"
