The challenge had already ended.
But many Blue Star players were still reluctant to leave, cheerfully bragging with players from other civilizations until the designated time arrived, then they left with lingering fondness.
Perhaps for many of them, this farewell was a permanent one.
After all, the odds of advancing to a D-level civilization were too slim, and most players here would find it difficult to ascend to a D-level civilization in a short time. Wouldn't that be a permanent farewell?
...
Accompanied by countless white lights flashing in the white space, all Blue Star players were declared officially returned.
"Ding, congratulations to the Blue Star Civilization for successfully advancing to a D-level civilization. The 'Civilization Remodeling' feature is now officially unlocked. We hope all players will continue to strive."
As the prompt sounded, it signified that this promotion battle had officially ended.
