A spaceship departing from the earth exploded in outer space. One of the capsules carrying some humans was ejected and landed on a planet near the explosion point. This planet happened to be an environment suitable for human survival, so humans survived here for another 300 years. However, a large amount of civilization information carried from the earth was lost at first, and only scattered parts were preserved. A human social system has been formed on the new planet, but they have to fight against the enemies of another civilization on the planet. Human beings have established seven colored kingdoms based on colors, while the black kingdom is the planet's own civilization, and both civilizations want to annex each other.
Intention: Human beings on earth cannot escape the essence of human nature no matter what environment and stage they are in.
