We learn that peng and zhuo have brought in a "vagrant doctor" to examine old master . . The doctor tells peng that old master is dying and that he should try to cure him, since it was the yan who brought him to this place. He is better than a person who took money without doing anything, peng tells his father. He says that they have already examined old man's heart and that his pulse barely feels. peng says that celestial energy is mysterious, and that it is best to not jump to conclusions too soon. He thinks that this man is "not a simple person" . He wonders if this man has some secret technique that he has never known before, and wonders if he could travel through his body and explore with his celestial energy.
