The Dark Portal?

On Blue Star, there is a mysterious and powerful organization. They possess technology that far exceeds that of all superpowers, and power that ordinary people cannot imagine. Their underground military bases are spread all over the world, and they also control 70% of the world's economic power. They have people at the top of every country, but no one knows about their existence. Even the heads of the superpowers have never heard of them. They protect the world and they use genetic fusion. The combined power of science and technology changed human DNA, allowing ordinary humans to gain powerful power. Just when they were preparing to rule the planet, the zombie apocalypse broke out. All previous plans were disrupted, but the plan was still carried out in an orderly manner. After two years of domination planning, the Dark Portal finally ruled the Blue Star, but their ambitions did not stop there. They traveled through time and space, traveling to various cosmic planes to invade and plunder resources.
