Ten years have passed, and Joonhee is finally going crazy. He has read all the medical books, found all the doctors in the world, and brought them all to see his patient. He can't even cure him of the cold, but he's going to find a way. He's been waiting for this for ten years, and now it's time for him to show up. It's not surprising, he says, that they found his secret study, but it would have been weirder if they hadn't known about it. He tells them to get out of there, because the place is only for the Black Sky School's leader. They should give up, and let him go. He says, "you bastard, how can you allow such filthy words to slip out of your mouth?" He says that he is like a family to his disciple, and that's why he is here. The whole world of the murim is based on law of power, and if you want to be the leader of this world, you're going to have to do it. This proves that the past ten years were a waste, and it seems to have been fruitful for him. He asks, "what's the real reason?" He wants to rule the world. He doesn't want to take his position as leader of the sect. He just wants to be at the top. That's all he wants. The only thing he wants is to reach the top, and rule the whole world beneath his feet. This is what he wants, and this is what makes him want to follow his master and his disciple.
