They did not doubt that Lu Xuan had the courage and the ability to do so.
This was because they had just learned from their informal channels that Lu Xuan took control of the Myriad Demon Valley, which had frightened the humans on Earth for many years.

He genuinely meant it!
When that happened, even nuclear weapons would've been useless when Lu Xuan controlled the endless army of monsters. With millions or tens of millions of these monsters having been killed, they were just cannon fodder for Lu Xuan.
There were seven billion human beings alone in the world, while there were 100 times as many plants and animals on the planet.
