Although Gustav had said he wasn't going to make use of the bloodline except in cases of emergencies, there were still times that the bloodline would activate by itself.
An example was when he almost absorbed the border during their travels.
He suspected earlier that a part of the energy would be absorbed into his body if the gravitational field was filled up but the system had shown that it would absorb the rest of the energy if the gravitational field was filled up.
Gustav would go to the forest area every day to try and train his control of this bloodline but even with that he still couldn't grasp control of it properly.
He had calculated that the amount of force generated when he made use of discharge after absorbing two blocks of light was equivalent to a small nuclear electromagnetic force with wild electric currents within.
