Question

I think people call then illegitimate children because their mother is a commoner or smth' Since most high level status may call them that

pure blood means both parents comes in a high status (prolly called blue blood) but if one of them are lower then they ain't a pure blood. Well that's what the novel think for themselves

Sorry this is just my own opinion of the matter (´-﹏-`；)(I hope it helps. . .)

I THINK it's because their mother is not an empress or a concubine. People think that the emperor slept with that red haired bitch to have kids but as you can see that's not the case. If the mother is an empress or a concubine that would mean they're "pureblood", of course having a concubine as a mother wouldn't be equal with an empress as a mother but its still not as bad as an non-titled as a mother.

I mean like power wise. The purebloods have a regular power but the illegitimate children don't. The dad is part of the royal bloodline but all the children's moms are just regular people. (Even though one is a commoner and the other is a noble, their bloodline isn't special except one has a title and isn't a bitch) Like, I don't think God knew who a emperor should choose to be their wife and made it so only him and his wifes children would have regular powers.

I should have specified I was wondering about the powers part. Sorry and thank you for the input.

Oh, I read the novel and it said that the royal blood and the Hebei blood don't go well together and that the chances for her getting pregnant as a Hebei by a royal should not be possible but the red bitch made it work somehow. The twins have both the Hebei and royal blood but since the powers don't match well together it's kind of like cold and hot in their bodies. I don't think it causes any harm to the twins though, it just means that their powers are weaker than a Hebei or/and royal.

Thanks for the help! I understand it better now!
