Humans have never stopped exploring the unknown world.

From the first hunting on foot to expeditions on horseback, later, the steam engine became the new favorite of the times. The automobile shortened the city's distance, the train's appearance took people to further places, and the plane turned the earth into a village. Finally, one day in October 1957, human cognition flew out of this blue planet and headed for space for the first time, opening the exploration of the vast universe. In the following decades, humans landed on the moon and Mars and Saw the Milky Way.

In this endless universe, there must be creatures unknown to human beings on some distant planet. However, even the Local Group of galaxies, which humans will never be able to get out of, accounts for only 0.00000000001% of the observable universe—a desperate number. This means that humans may never hear the signal of alien civilizations, but this may not be a bad thing. The universe is a jungle, and In this endless universe, will never avoid conflicts, occupation, colonization, and even labor between tribes.
