Logan explained to the Demon King, and this explanation was very much approved by the Demon King, who couldn't help but admire Logan. After all, Logan had figured out the crux of the problem without even having completed a single lap in the Secret Land.
"The Demon Beast Secret Realm is entirely composed of the Monster Beast Clan, who inherently know nothing about arrays and alchemy. Although we have recruited quite a few talents over the years, if we take stock, at most we have a hundred Array Masters, and they are all half-baked. A thousand people are really powerless."
"However, since you have spoken, I will have someone go to the outside world to capture them. I will send out tens of thousands of people, and within one day they should be able to bring back tens of thousands of Array Masters. Not to mention the Western Wasteland, even going to the Central Region would be fine."
