Scientific legend: The universe was originally dark. Since the Lord of Nothingness broke his bottle of light, the colorful planets have shone brightly. They work hard to burn themselves, dedicating their light and energy to the darkness. And all the dedication is only for one thing... Humanity has been discovered! By the end of the 21st century, the great leap of human spaceflight technology, the great development of the moon and Mars, humanity has officially freed itself from the shackles of the earth, and started the pace of crazy spread. However, the more progress, the more you discover your own insignificance, and the more terrified you become. Once a great scientific prophet said one thing, alien life must exist, and humans should try to avoid contact with it, because this is not a good thing. But in modern times, whether it was the UFO flying past the solar system or the regular light that was constantly shining at the earth, these phenomena proved that human beings may have been discovered by extraterrestrial life. Among the modern people who worried about the world, a new anxiety was naturally added. May the gods of the universe bless mankind!
