His physical defenses will be even better now and he’ll have more options to exploit his poison if he can cut his opponents with solid attacks also wonder if the gems can be conductive for his lightning so many possibilities and options!!!!
I have a question author-sama, since the gem primogenitor passed on his gem manipulation in that Experiment, it means that he can no longer pass it to someone else since he doesn't posses it. So how will he gift it to MC?
