Mutated Virus? the End Is Coming?

Zhang Xiao is a junior high school student. What an unlucky year 2440 is. The whole world has been ravaged by viruses. The earth seems to have lost its vitality in an instant. This virus seems to be able to evolve into a new virus at any time. This virus is originally from the ancient XG virus, but it was combined with rabies and many viruses under artificial conditions to form a new super virus. It contains almost all the advantages of viruses without disadvantages. Human beings feel powerless for this! Even the strongest countries M and E have been captured. There are only a few scattered small alliances of survivors left in the world. Country Z is okay. It has been holding on until now and is still looking for survivors in various major provinces. This world is what we call the Hades Century. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
