At the beginning of the 22nd century AD, humans created a group of synthetic humans similar to humans in order to explore space. They launch synthetic humans into unknown cosmic worlds just to explore new places to live. However, after a long period of evolution, synthetic humans gradually developed their own consciousness. They are unwilling to be enslaved and become human experiments. So, at the end of the 22nd century, a war with humans broke out. The synths prevailed thanks to their stronger bodies and higher levels of technology. Known as the "War of Independence" in history. After this war, the synthetics were completely independent and mainly active in outer space.
At the same time, with the development of medical science, vampires, a species that flourished in the 19th century, were discovered. As in the legend, they hate light, are thirsty for blood, and possess the innate "power of gods." However, due to outdated ideas, he has never been able to make a difference in the field of science. They began to infiltrate their own forces into the human camp in an attempt to steal human theoretical achievements. After humans discovered it, all vampires were eliminated from the core area, which was known as the "Great Blood Change" in history.
Due to fear of the "power of gods", humans developed a similar "Dark Night Star". Although the effect is weak, it can slightly compete with it. Humans who possess the Night Star are called "superpowers."
The world is peaceful on the surface, but there are undercurrents underneath.
By chance, conflicts arise between vampires and humans. The commander of the synthetic base, Qin Shi, and his adjutant Ye Qingsi went to Earth to discuss cooperation with humans, hoping to eliminate humans. Things did not develop according to plan, and accidents happened one after another.
