Noah felt the breakthrough of his dantian drawing close only after three centuries spent training in that peaceful period.
It was needless to say that such speed surpassed the realm of the talents, but it wasn't as monstrous as his other centers of power. Moreover, he felt that he lacked something to finalize his advance.
Still, peace worked against those seeking enlightenment. Noah could only cultivate and meditate since no adventure or opponents gave him the chance to test himself.
Of course, Noah would act if the issue persisted for too long. It wouldn't be his first time doing something reckless in the hope that it benefitted his growth, and the Elbas family was always there for him.
His training didn't reach that point yet, so he continued to use traditional methods to train. For Noah, that meant using the Seventh Kesier rune, eating peak rank 5 magical beasts, and cultivating with the Demonic Sword.
