Ru looked like she grudgingly acknowledged the argument, even if she wasn't entirely satisfied. It was true that now that they were exploding the number of Martial Sages in the world, they needed to expand their civilization to create room for territory and political power for these new Martial Sages; the internal pressure would eventually cause a civil war to break out in some fashion in Panama.
Of course, with Rui having broken through to the Transcendent Realm, he could singlehandedly subjugate even a truly massive number of Martial Sages, but that was deeply unhealthy and would create extremely intense domestic tensions.
On top of that, needing to keep all of that in check would constrain Rui himself. He could leave Gaia for any matter because the second he did, he would have to worry about rioting Martial Sages.
