The next morning, Proteus asks the waiter why he wants to work with them. The waiter tells him that they need him because they were able to track the leads up until now, which proves their abilities. If they cooperate, they can prove their sincerity. The next day, the waiter tells the boy that he used to eat at this restaurant often, and that he knows he doesn't want to work for them, but he still agreed. The boy tells the waiter that he's going to tell them something serious. He says that if they work together, he can find his physical body, even if the chances of finding it are slim. He also says that he can blow that person's name off, and he'll be certain that she knows him. He asks if she can really see him, and the waiter says he has no reason not to lie to her. He then shows the boy the painting he restored, and asks if it is the same one Lin Xiao saw when he was a kid. He was wondering if the same thing was the same fire he saw as a child, but neither his father's documents or the police records can prove that the fire and the mountain are real. They decide to look at the sky pit.
