The "Good Cat Civilization" invariably takes a group of carefully chosen orphaned boys and girls to the "Wild Grass Star." These children will be the last seeds to carry on the civilization if they flee.
Passing through this long, shadowy tunnel.
The leader of the Good Cat Civilization arrives on the surface, where trains are parked en masse. Large numbers of troops and soldiers stand ready, prepared for departure. This is an incredibly fearsome force, one capable of standing against any Fourth-level Civilization.
As a longstanding Fourth-level Civilization, it does have this foundation.
Unfortunately.
These foundations appear as fragile as bubbles in front of those trains, bursting at the slightest touch.
