The sibling doesn't react to holy power. So he can't be healed. Same goes for MC, she can only be healed by magic power, and our ML has that.
They’re not asking why did the holy power didn’t work on her sibling ,they’re confuse on as to how could have her sibling know that her holy power didn’t work on him. Since at the start of this story it was pointed out that the FL was in a coma/asleep for over 20 years (so conclusively her and her sibling didn’t officially met before in that era/timeline). I personally would like to be enlightened , there’s so many plot-holes in this story that we hope some readers who already finished it might gave us the answers we want.
Thanks for the reply haha, I reread the chapter and it seems that it is after she woke up according to the clothes they are wearing. But I don't really like the time line, or should I say the timing in which this was explained? It seems too rushed and illogical... Like she woke up and immediately we were introduced to her sibling (with that healing part) but that couldn't have happened yet become she just woke up. So maybe that's why it was so confusing to me.
They could also know that his lungs couldn't be healed using holy powers cause the sister isn't the only one with holy power hers is just the strongest of the holy powers. So they could have already tried to heal his lungs
I don't understand... In chapter 4 it's said that her sibling has weak lungs but she doesn't respond to the MC healing but in the next chapter it's said that MC was actually asleep for 20 years right???? When did she have time to try to heal her? Was it before she fainted when she tried to protect the sibling from the emperor or what....?
