Even when it comes to navigation, it's actually very rare for civilizations to open new routes.
What's more, the universe is truly vast and boundless.
How many fixed star systems are there in the entire Milky Way Galaxy?
Over 400 billion.
No civilization can fully explore it all, and crucially, there is no need. If one relies on this exploration method to find civilizations, the cost is enormous.
Moreover, for powerful civilizations, only other powerful civilizations hold value.
Powerful civilizations are bound to explore the cosmos and will eventually step into the dark abyss of the "Mude System," one after the other.
For instance, isn't Human Civilization planning to search for other D-level civilizations at this moment?
"Does that mean this civilization is the type that develops cautiously?" Tao De quickly asked.
"Exactly."
