His opponent did not expect him to destroy that fireball in that manner. More importantly, he began to panic when he realised Sam was more powerful than him.
He is unable to make a decision at that time, which is his biggest mistake. He should have remained calm. This is another characteristic that every Warrior should possess.
However, in this situation, Sam's opponent was unable to remain calm. Sam is obviously not going to waste that time. He used the movement technique to appear close to his opponent again and attack him.
"Clang!!!!!"
"Ahhh!!!!"
This time, his opponent was unable to defend himself. He was sent outside the battle ring. More importantly, his opponent's armor had been destroyed. Sam's opponent let out an agonizing scream.
"Sushh!!!!"
He fell to the ground. His whole body is in pain. He is doing his best to get up from the ground. Unfortunately, despite his efforts, he is unable to do so and ultimately loses consciousness.
