They saw the gun in Arno's hand.
Arno fired three times in quick succession, three pale purple beams piercing through the bodies of three men, killing them.
Then, he quickened his pace, moving closer to the center of the explosion.
Along the way, he saw many remnants.
They appeared to be a certain model of Feedback-Type Power Armor, slightly different from the Servant Gods used by the Alliance, likely purchased by Zelos through trade from other places.
Even the elites in Feedback-Type Power Armor couldn't withstand the thermal bombs. Multiple parts of the armors had suffered severe melting.
Continuing forward, closer to the center of the explosion, Arno's gaze suddenly tightened.
He noticed an oddly intact area of the ground ahead.
Several thoughts flashed quickly through his mind, and he almost confirmed the most likely one: a miniaturized personal energy shield!
Such a device was rare and expensive, but for someone like Zelos, having one wouldn't be surprising.
