In 2128, non-renewable resources are almost exhausted, and the United Nations has clearly prohibited their collection. As a result, the market is mainly used for electricity converted from wind energy, light energy, and water energy. Wind dust can be seen everywhere on the road, and solar power panels are necessary on the roofs and walls of buildings. Due to innovative research and development of science and technology, the conversion rate of these green energy conversions into electricity has been improved, and the storage has also been improved. However, it cannot keep up with the huge consumption of the world as a whole. Scientists continue to actively develop space, hoping to find a new way out, a new world or new energy in outer space. As a result, the remains of a higher civilization, the Intelligent Brain, were discovered on a certain planet, and they learned that there were also wars with higher civilizations in outer space. At present, the plundering civilization has achieved an obvious victory, and is expanding. The earth will soon be discovered. Dragon Kingdom scientists will bring the Intelligent Brain back, and the Intelligent Brain has something to do. In order to improve the combat quality of human beings around the world, they jointly developed "Dark Domain". In the game, human brains and body values can be developed. The male protagonist Chen Chen accidentally activated the game helmet bound to the female protagonist Lin Xingyao, and began an adventure in a new world.
