on ch 26, why can’t he kill the old dude? is it due to his high level dominance?

I think it might've been because he had a certain relic that kept him alive? Or maybe Joo-Heon had some plans for him later.. －.－)
Anyways I forgot but maybe!

thanks i’ll prob know later

Because the old man has an immortality relic that keeps him.alive, that's also why he doesn't even die when he was trapped all those time inside the tomb
