The cave shook as Wolf's greatsword connected with the centipede's body, to be more exact it connected with the end of the body which was lifted from the ground and flung up with great speed.
The centipede's body and Wolf's greatsword collided as flames burst out around them, even with the incredible boost from Wolf's ability, his flames were still unable to deal a lot of damage to the monster. That wasn't the only problem as Wolf's sword was unable to cut deep inside as the centipede's steel-like plates made it hard to do so.
Wolf was unfortunate enough to hit a plate right away, as that was the toughest part of the centipede's body, he was unable to deal a lot of damage with the attack, still, his sword was able to cut through the plate thanks to its sharpness and the powerful flames that melted a bit of it.
