"At this moment, if you send out a large army to destroy this civilization, it would consume a lot of resources, making it somewhat not worth the cost."
"Not very cost-effective."
"So just don't bother with it."
"Let it develop on its own, grow wild."
"After all, in the cosmos, you actually don't need to take action against civilizations that are your enemies. Sleep for a few hundred years, and you'll find that civilization has perished without you knowing when."
"If they happen to develop, then go to war. If you win then, you get to enjoy the spoils."
"The 'Cosmic Landmine' is like a threshold."
"When you're below its threshold, it won't bother you. When you trigger its threshold, it will come after you. If it can't defeat you, then no one will bother you for the time being, until you trigger a threshold set by a more advanced civilization's cosmic landmine."
"Cross this threshold, and everything will be smooth sailing."
"Fail to cross, and it's death."
