What a marvelous piece of soundwave magical equipment!
Li Yao analyzed the battle. The hammers that the black-armored general utilized seemed to have the ability to trigger the fighting will or the sense of terror by stimulating one's nerve endings with soundwaves. It was a rather impressive piece of magical equipment for collective attacks.
However, since the same soundwaves could trigger the fighting of the soldiers on his side and devastate the enemy simultaneously, some sort of advanced 'friend-or-foe identification rune array' seemed to have been activated.
Li Yao pondered carefully for a moment but failed to figure out the mechanism of such a rune array.
It suggested that the Sector had special knowledge in terms of refining, too, which was worth studying.
The barbarians' roar seemed to be a call. A bizarre-shaped bird, with hideous claws and teeth, suddenly flew into the sky in a panic because of the shock.
