He knew that there were many demonic beasts in the Demon Realm, many more than the number of humans. But no matter how many there were, they would be all killed eventually.
"Little brother," Wang Xuanyi's wife said. "The Demon King that Xuanyi just killed is the weakest among the heavenly slaves. The power of the heavenly slaves far exceeds your imagination.
"Let's not talk about those heavenly slaves for now. The demonic beasts of the Demon Realm are the lackeys of Heaven. When the heavenly slaves wake up, those ordinary demonic beasts will be born endlessly in the world. No matter how strong we are, it's impossible to kill them all."
Zhou Shu frowned slightly. Is such a thing possible?
The more he knew, the more despair he felt.
No wonder it was said that Wang Xuanyi and the others had died or fallen into a deep sleep back then. It wasn't that they didn't want to destroy the demonic beasts but that they were not strong enough.
