"As for why not exterminate Luo Hou and other strangeness?"
"I see it this way; after the Heavenly Conquest, Chaos and Primordial became too quiet, lacking the vitality of your times.
In particular, in the Chaotic World, the strong who emerged from Primordial only think of achieving transcendence; everything else is trivial in their eyes, not how a world of the mighty should be."
"People like Luo Hou fell into strangeness, always thinking of using the Power of Calamity Unlucky to taint the beings of Chaos and Primordial World to augment themselves. Having ideas leads to actions. I didn't annihilate them; they are the agitators of Chaos and Primordial World, constantly generating pressure for the beings of both worlds.
Only in this way can the potential and inspiration of the creatures from both worlds be spurred, thereby enhancing the vitality of both worlds!"
"Otherwise, both worlds will be in danger!"
