After months since he began his seclusion, Minos had finally managed to bring a tiny fraction of the powers of those bones to the light.
It was nothing beyond comprehension or absurdly fantastic for him to have advanced a level in less than a year. Still, it was enough to benefit him and his people significantly.
After months of using his innate ability daily for much of the time he was cultivating, Minos had managed to subtly steal some of the powers of those bones and increase the level of his and other souls there!
He had managed to do the same thing he had been doing since he had advanced to the 8th stage, steal a target's cultivation and transfer those powers to other people.
