In the year 4044 of the Era, the earth was covered with clouds at some point, and the sun has never been seen since. The next day, unknown acid rain suddenly fell. All known creatures on the earth died when touched. The surviving animals and plants were eroded by the acid rain and mutated to varying degrees. In just one year, the number of humans has decreased sharply. At the same time, natural disasters such as tsunamis, earthquakes, and droughts have struck in turn. With the exception of three continents, all other islands have been swallowed up by the ocean. The International Joint Biological Research and Conservation Agency developed a method to combat mutant species the following year, and "regenerators" came into being.
The first batch of regenerators, led by the first regenerator "No. 1" On Earth, became the most powerful beings protecting mankind on earth. After ten years, the coastal boundary zone was finally used as the dividing line between humans and alien species. Human beings occupied the land and alien species occupied the ocean.
One day, a group of young people with different abilities and personalities fought their way back from the ocean assessment safely and threatened to save the earth. However, the next day they were seen picking up bottles on the street!
Purpose: Protect the ecological environment and build a green earth together.
