Xinghai Alarm Bell

When humans travel across the sea of ​​​​stars and colonize thousands of galaxies, they assume that they are the only civilization in the universe that has gone to deep space, and they alone enjoy the glory of conquering the universe. But an ordinary deep space salvage, an ancient Eastern detector from eons ago, broke this certainty. We finally know that countless civilizations have already been one step ahead of mankind, setting foot on the sea of ​​stars and looking into the deep space. It turns out that we were never the first movers. This truth makes human beings who have conquered the galaxy fall into a heavy reflection on their own civilization.
