Thales quietly calmed down while he stood in the training ground. He sensed the increasingly active Sin of Hell's River flowing through his entire body again.
Ever since his adventure at the Great Desert ended, he noticed that his Sin of Hell's River had become even more condensed and sufficient for his use. Compared to him only being able to use it for a short period of time in the past, right now, it could be used for a longer period of time.
And after his Power of Eradication faded away, the fatigue and soreness that were left in his body also decreased.
'As expected, what doesn't kill you makes you stronger,' Thales thought to himself.
Of course, that did not come with no price at all. Ever since he was heavily wounded by Nicholas, he could not use his left wrist as nimbly and at ease as before. That had more or less affected him in the usage of his shield.
