@Hollow7F The MC basically has maxed base stats and maxed out all the things that can be passed down ex. physical strength from his dad and magic power from his mom. So his kids shouldn't really be able to gain anything from his wives except beauty from here on so, they should be equal to him and probably better looking.
So... How irresponsible are his parents?
His kids are going to be even stronger than him, yet she teaches him to be strong in order to impregnate other species girls?
What am I even doing, why am I even trying to make sense of this manga!!!
I agree with some earlier posters - technically he should be forced to only breed with other evol orcs, since his kids would destroy the world. Doesn't matter if they aren't more powerful than him, he almost destroyed the world over a tantrum.
But I guess they can try to perfect the art of sealing powers and let the kids grow stronger in a more relaxed pace.
@monkey123 - You know, I bet you could accomplish the same thing with a rubber band a paperclip and a drinking straw.
. . . Oh come on, it's just an orcish joke!
