Before Argon could understand what was happening, every single one of his attacks was being blocked by the reinforced arms of the creature before him...
However, that was not where it ended.
Not only was it beginning to block all his attacks, it quickly moved to parry them instead.
Argon's techniques utilized the power of momentum. Even if it blocked the attack, Argon's technique and control over his toki allowed him to move the swords in a way that allowed him to keep the momentum of the last attack.
It could be seen when he first attacked the storm of spiders. Every time he killed something, the toki around him would increase while his next blow became even stronger than the last.
However, not that the creature was using his momentum against him; it was getting much harder to fight it.
