Chương 2930: Nine Mountain Ranges

Even the perfected Grotto-heaven was surrounded by the Nether Ghost Fire and Demon King Gai Yu's Essence Spirit could not escape.

Under the horrified gazes of the Demon Generals, Demon King Gai Yu was burned into a skeleton in a few breaths and his Essence Spirit turned to ashes, dying on the spot!

"Wha—"

The hundred-odd Demon Generals in the hall were shocked.

This was a peak-level Fiend King!

However, the purple-robed man did not even look at Demon King Gai Yu the entire time. He merely flicked a flame casually and killed the latter!

What sort of power was that?

Was it a quasi-Emperor?

Or… the Emperor realm?

More importantly, the purple-robed man was clearly on the side of Demon Empress Blood Butterfly and they had just expressed that they wanted to submit to Blue.

If the purple-robed man attacked them, he could probably kill them with a single breath!
