Suddenly Zero uses the bullet time and instantly he doesn't attack one of the leopard monsters that is about to reach him from behind. Waiting for the moment when those. Monster will lose their stamina and he will take that chance to kill these Monsters.
All this time you can say he took the help of his bullet time and the movement technique but still many times he got hit by their attack. It is a good thing that most of the attack got absorbed by the armor and he did not take that many injuries.
You have to say that those Monsters are also very strong because even though the armor receives most of the attack, he can still feel the impact which is enough to injure him.
But those injuries aren't serious. Well, on the other hand, he can already see those Monsters losing their stamina and this would be the perfect time to kill them. Without wasting a single second he uses the energy boost to increase the power of his bullet time and the moment technique.
