Although Chi Xue and the others had killed many Demon Soldiers, they had to admit that the Demon Soldiers could still pose a considerable threat to them. In particular, after teleporting, they could self-destruct and easily destroy their grand formation. If nothing unexpected happened, their self-destruction would likely create obstacles for Chi Xue and the others in the future, delaying their arrival at the Demon God Forbidden Ground.
In short, the more Demon Soldiers there were, the better it was for the Lord of the Universe. So, even with the ten-thousand-year delay, he should have sent out large numbers of Nine Nether Nether Soldiers to capture cultivators from the starfields and turn them into Demon Soldiers. Yet he hadn't done so, leaving Chi Xue and the others puzzled.
But it didn't take long for everyone to figure out why—the Lord of the Universe needed a long time to teach the Nine Nether Nether Soldiers powerful secret techniques for the Demon Soldiers. He simply had no time to turn the starfield cultivators into Demon Soldiers.
It made sense. The Nine Nether Nether Soldiers could be sent to capture the starfield cultivators, but only the Lord of the Universe himself could transform them into Demon Soldiers. And turning large numbers of cultivators into Demon Soldiers would take a very long time. If the Lord of the Universe had to spend more time teaching the Nine Nether Nether Soldiers and Demon Soldiers powerful secret techniques, then he naturally wouldn't have time to transform the starfield cultivators.
Since he had no time for that, there was little point in sending the Nine Nether Nether Soldiers out to capture large numbers of starfield cultivators. That was exactly why the Lord of the Universe hadn't done so.
"Mm, that's the only explanation that makes sense." Po
