This problem is not something I had thought would occur, as most bloodline source energies would just ignore it as it would disappear; his own bloodline had been doing it before the breakthrough began.
The bloodline source energy had reacted to the residual aura of the Grimm bloodline mutation I had used to stimulate the bloodline.
I have used different types of Grimm bloodline corruption that I had collected, and damans bloodline had fought and destroyed each one of it with struggle, but after each struggle, it had gotten stronger.
Some of the residual aura had been left in its body, and it was so minute that even his bloodline had ignored it until now, when the source of energy reacted to it, directly destabilizing the bloodline, which is at its most vulnerable.
The instability of the bloodline is a very bad thing, especially during the breakthrough; it could make things instantly spiral out of control.
