To travel to every corner of the universe, they had to possess the corresponding level of navigation.
This was also the first problem every civilization had to solve. The first step in turning science into application was to build a Warp Engine. Whether they installed it on old ships or newly designed ones, the goal was to leave this place.
Now, every civilization had extracted Vacuum Zero-Point Energy by its own means, and large-scale industrial manufacturing had begun accordingly.
Previously, because of the energy problem, every civilization had reached the point of dismantling ships. Now, none of them had that worry anymore. While manufacturing new Warp Engines, every civilization had also set up pieces of energy extraction equipment. These devices were like oil wells, continuously drawing energy from underground.
This energy would be used to perform work, then undergo Energy-Matter Conversion to become the materials each civilization needed.
Any normal cosmic space contained Vacuum Zero-Point Energy, almost inexhaustible and unlimited. With Energy-Matter Conversion technology, matter could be obtained continuously.
After becoming Cosmic Civilizations, they finally cast off the drawback of needing Star Systems to provide matter. After mastering Vacuum Zero-Point Energy, every civilization, relying on its previous technologies, had truly achieved creation from nothing.
As time passed, many civilizations successively built their own Warp Engines and completed trial voyages.
Warp Engines were the creations that most clearly revealed the technological level of each civilization.
Among the eighty-four civilizations, nearly eighty percent produced Warp Engines that could only reach 392 times the speed of light. This was the navigation speed of the early stage of a Cosmic Civilization.
As for the remaining dozen or so civilizations, such as the Abyss Civilization, Kroll Civilization, Daya Civilization, Pouchkind Civilization, Aran Civilization, Memoda Civilization, Green Sea Civilization, Falcon Civilization, Silver Heart Civilization, Divine Matrix
