How will mc's hand be healed? And when will it be healed? And will it cause Mc to be in danger when he needs to use his powers in the future?
It's been a long time since I last read the novel so I'm sorry if my info is incorrect but from what I remember... The hand will not be healed but Yuder body adapted to the power of the red stone and he can somehow channel the power from the red stone in the future.
Spoiler
This is how he will help the current emperor to awaken and stabilise his vessel.











Um not to be that person buuuut I don't think the butler feels romantically involved with blue hair uuum more like father-daughter...
