The A-rank zombie attempted to evade the attack but when he was doing so, he inexplicably lost his balance and was about to fall on the ground.
Using his lightning power, he managed to prevent himself from falling on the ground but shifting his focus and attention towards that had caused him to lack the time to evade the flame and ice bullets.
When the flame and ice bullets came into contact with the A-rank zombie, the flame and ice elements within it collided with the lightning on the A-rank zombie's body.
The A-rank zombie had not only used his lightning to improve his agility but to also wrap it around his body as armor. So when the flame and ice bullets managed to penetrate the lighting armor, the left was already negligible and it couldn't do any harm to the A-rank zombie's skin.
However, Winston wasn't discouraged when he saw that his attacks became ineffective.
