What does the last part mean?

Could be wrong, but it was an “injury from touching the stone” and had stuff coming out of ML’s hand. so I think that’s gonna be MC eventually in this life, since his hand got affected

im reading the novel. past kishiar revealed to yuder that he accidentally injured his hand when they retrieved the red stone (it's the same injury as yuder) but with greater effect on his body than yuder's (it'll be revealed in the next season, the injury and its effect)
