Someone responded.
The White-Headed Eagle Fiend immediately followed, "Exactly, exactly, exactly, the bosses are right! Kill him!"
"Do we need to lift a finger to kill him?" someone sneered, and then with a flick of their hand, runes lit up on a distant mountain peak. The runes took flight, and the mountain was overturned in an instant!
A colossal ferocious beast burst out from beneath the mountain, roaring up to the heavens!
The other Demon Kings realized what their opponent meant—letting loose the beasts!
This was a chance to test the enemy's true strength, and whether it was their foes who died or the ferocious beasts, they wouldn't count it as a loss. After all, these ferocious beasts couldn't be tamed; if not kept under seal, they could only be killed...
Now was the perfect time to use them!
