Actually, don't be fooled by the Dark Forest Law. Within the Three-Body Universe, it deterred the Three-Body People and ensured the survival of human civilization. But on the scale of the entire universe, the Dark Forest was really just a minor matter. Only weaklings like human civilization or the Three-Body Civilization would regard it with such awe. Any civilization even slightly stronger would disdain the Dark Forest entirely.
Put simply, Dark Forest deterrence meant drawing a stronger existence into attacking one's enemy—killing with a borrowed knife. But if one dared to kill with a borrowed knife, the odds of being discovered were practically one hundred percent. That knife could kill the enemy, but it could kill its wielder as well. Simply put, it was a method of mutual destruction.
What true powerhouse would resort to a trick like killing with a borrowed knife?
The universe was unimaginably vast. No one knew how many civilizations existed within it, much less how many powerful civilizations there were. Don't be fooled by how humanity later used a Dark Forest strike to destroy the Three-Body star system, or how even the Solar System later suffered a dimensional strike and was reduced to two dimensions. In truth, the civilizations that had appeared so far were merely that impressive.
The Singer Civilization had effortlessly destroyed two civilizations. Did that really mean it was powerful?

No one knew what the Singer Civilization was truly called. The so-called Singer was merely an individual from that civilization, engaged in the work of cleaning up "garbage." Clearly, Earthlings and the Three-Body People were garbage in the Singer's eyes.
The Singer Civilization was merely a name
