5,000 Years ago, the earth once again ushered in the Little Ice Age, and serious faults occurred in the earth's culture. Fortunately, some advanced technologies were preserved. At the same time, the sky and the earth were filled with dark matter.
The small glacier ended after 1500 years. In another 520 years, human scientists discovered that by absorbing the dark matter between heaven and earth, they could condense it into a new energy element in the body. This energy element was called magic by others.
