In 2028, a new energy crystal was discovered on the bottom of the Pacific Ocean. Scientists found that one kilogram of the crystal can emit a quarter of the energy of a nuclear power plant. But at that time, scientists were unable to stably extract energy. Five years later, Han Xiangbei, a national treasure scientist of the Flower Planting Country, developed a new energy converter and successfully extracted energy from the crystal. This is where it all started.
