Two meteorites fell to the earth, and the cosmic demon Bermuda and the giant of light visited. To the earth, it was like a signal accidentally leaked out in the dark forest, exposing the planet to the sight of all civilizations in the galaxy. It attracted the trampling of alien iron hooves. Ultra warriors went on to protect this planet and regarded it as their second home. But the earth is the earth of mankind after all, and it needs humans and the planet itself to protect it. It is surrounded by darkness and pain. The earth is shrouded, and whenever people feel hopeful, the light of Gaia will appear.
