In 2056, just a few decades ago, the earth's resources were greatly reduced, and the earth's population was greatly increased, making the earth overwhelmed. A group of scientists proposed the ball-within-a-ball plan, which uses a large amount of almost all resources to establish a protected area and only allows a very small number of people to enter the protected area. It will be equipped with a UV filtration system, air purification system, etc. This statement was opposed by most people as soon as it was put forward, and soon it seemed to disappear from the world. But they ignore that the people who make decisions are never those who can only bark. Thirty-six years ago, fourteen protected areas were established around the world. A team composed of various leaders, wealthy people, and scientists have enclosed more than 90% of the earth's proven resources in protected areas. The number of people who have entered is less than one percent of the human population.
The large number of humans who have not entered the protected area are called wanderers. In the past few decades, the external environment has indeed continued to deteriorate. A large amount of radiation and virus mutations have turned many animals and plants into completely unknown creatures, and some have evolved intelligence. Humans call this creature Fuyouqie. A small number of wanderers have mutated their bodies. They have built gathering places in every corner of the earth to gather wanderers. He even attempted to attack District 14. Of course, District 14 cannot sit still and wait for death, so they invested a large amount of biochemical viruses into the outside world, as well as us.
