Doomsday Era

In 2060 AD, the earth's glaciers melted, and tens of thousands of viruses swept the world. The accompanying floods, droughts, and high temperatures made it difficult for humans to guard against it. 12 Billion humans died and injured more than 5 billion in just two years. Humanity has to accept the sixth mass extinction. At a time of crisis, German biologist Doppler published the famous replication plan, which allowed mankind to endure for another 200 years. The 300th generation of humans experienced genetic mutations in extreme environments. There were three more immune cells in the human body: X cells, medium cells, and canned cells. There are three subspecies of X cells: x-1, x-1b, and x-2. These three types of human beings are collectively called evolved humans or mutant humans, and their X-cell human appearance features include attack, mutation, and defense. The appearance characteristics of people with medium cells are wings and gills. The appearance of tank cells does not have many features, but its main feature is that it cures and prevents disease.
