In the vast universe, the earth is just a grain of sand in a barren land of the Milky Way. There are trillions of civilizations like the earth existing in various ways of civilization evolution. For example, in the early days of the earth's spiritual civilization, which was rich in spiritual energy, the gods and monsters in the Classic of Mountains and Seas appeared. I don't know why the earth is lacking in spiritual energy, so today's technological civilization has emerged. The story we are telling is about one of the Hercules galaxy clusters 650 million light-years away from our earth. It is similar to the story of the planet in the ancient times of the earth.
