First, Thank you author for another wonderfully done chapter, and the fact that you are still doing all of this on your phone is just amazing.
Second: They haven't used Princess Carmilla's power yet. Her strongest spell seems to be to shunt the damage she takes to someone else, my guess being the last person to touch her without harming her, so they could still trying kill her and have the damage go to the king, thus bypassing the One Body One Soul ability, but I don't think it is going to work.
Third: The real mind fuck here is that the Sage doesn't actually have any sage skills. If that is really the case, why would he have been given that class, just to be a Big Bad? I'm not buying it. I think there is a skill and MC is going to find out what it is while he is unconscious, because it is going to be the Chekov gun event in this.
Fourth: The King said that he always knows what his daughters are thinking, and I think he meant that quite literally and already knew that they were going to try and over throw him, but because of the conspiracy, he didn't know when and where.
