"Plop, plop, plop, plop..." A series of dull sounds rang out. Almost all of the skeletons and green-furred zombies were struck at the back of the head, the flying edges extraordinarily precise, hitting all thirteen wraith entities.
The bodies of nine green-furred zombies that were hopping about fell suddenly. The heads of five of them had been shattered, their bodies convulsing as they fell to the ground, while the others, despite their heads being partially broken, were still resiliently struggling to get up.
The four skeletons, who had obviously stronger defense, staggered after their heads were hit, but were not totally broken.
At that moment, an invisible ripple quickly spread out, hitting the four skeletons simultaneously. Their bodies went rigid and the Soul Flames in their eyes violently trembled.
Little Evil's Mental Shock had arrived. These wraith entities, controlled by the Soul Flame, were most afraid of attacks like the Mental Shock.
