If we compare the entire universe to a piece of cheese.
The densely packed stars, such as galaxy clusters, are the cheese, while the voids are the "holes."
Full of holes.
Different civilizations have different names for this area. In the Kasha Civilization, it's called the "Void," an extreme void where there's nothing, and no train can traverse this region, not even his.
There isn't even a resource supply point on the way.
Although the energy consumption of his train's advancement is reduced by two 99.9%, equating to almost no energy consumption, it still relies on absorbing the core energy flowing in the universe while traveling. Core energy leaks from planets, but this area has no planets at all, so where would the core energy leak from?
Forget the Supermodel Effect.
Even if the Supermodel Effect appears, it would still stall halfway, stuck there.
