In 2516 AD, after the Global Day of Judgment, a high-level alien civilization suddenly attacked the earth in a large scale! In order to protect the earth's civilization from external invasion!

But unfortunately, after the Battle of the Solar System, the earth was completely exposed, and the various declines that had happened over and over again! For a time, the major alien civilization forces learned that the Shenhe Civilization of the "Panguan Era" had long ceased to exist! Then they invaded the earth's civilization in a large-scale and crazy way, and the earth suffered a disaster as a result.

Every relic of prehistoric civilization left on the earth seems to be writing this cruel law of nature: natural selection, survival of the fittest. This is a natural law that all civilizations on earth cannot escape, including the current earth civilization. The birth of every new species may mean the disappearance of one of the existing species. Natural enemies eliminate each other's numbers to ensure the balance of the natural ecology. However, no one knows that companion species are the creators and creators of this natural law. That is an existence that can eliminate all natural competitors. But by the time humans understand this, it's already too late... Because companion species are about to end all of this and wipe out all existing human civilization.
