That means it's useless... I wonder why the Emperor wanna have the prince a child from that alfa
Yes
Probably in order to make a claim to the captured princess lands.
He wants something from that prince like magic that the prince ancestor passed to their children. Just read in the chapter 1, the prince and his father say something about awakening..
I mean the alpha prince
what does ineffective mean? like the birth pill control not going to work and he will be pregnant?
