And...
Shang Lin picked up a special "letter."
It wasn't a participation letter from the Ancient War Gods, but rather from some Ancient Gods.
After all, when speaking of Stellaris, how could one forget the various war criminal activities? Moreover, such incidents had already occurred in the previous game, resulting in the grand spectacle created by the Concentrator Civilization. As expected, even the distant Ancient Gods felt fear.
"A surprising new discovery, the Ancient Gods shouldn't be able to extract value from the universe anymore, they have been crippled by the Gods, and their method of obtaining value isn't through emotions. Most Ancient Gods acquire value through the 'spread of curses'."
Lifeforms without curses on them cannot provide value to the Ancient Gods, after all, they are the very embodiments of curses.
Does the Concentrator Civilization carry any curses?
But why did the Ancient Gods feel terror?
