1558. Ecstasy
Sword Saint experienced different emotions. He felt confused at first. Noah didn't do anything specific, but he had managed to express more power seemingly out of nothing.
Then, an idea popped into Sword Saint's mind. Noah's second slash carried something that an expert like him couldn't find with his usual training.
Sword Saint was a maniac. He had dedicated his entire existence to the sword and had exchanged blows with countless experts to polish his arts. His mind didn't even contemplate the idea that there could be something outside the centers of power.
However, there had to be an explanation for Noah's superior prowess. His might didn't come from his centers of power, so there had to be something else, a different source of energy that Sword Saint had never considered before.
