In 3062, mankind reached the first level of civilization. Due to wanton destruction and transformation, the earth accelerated its approach to the star sun, and the temperature at the hottest point on the earth's surface reached nearly 160 degrees Celsius. The earth's air contains various toxic smog, and the probability of human cancer increases to 62%. The earth has changed beyond recognition and is no longer suitable for human survival. The global population migrates to planets that are highly similar to Earth, possessing significant air and water, atmospheres, and flora and fauna that are intrinsically similar to Earth. The planet is named "UB-4702", "Green Planet".
