The teacher decides to take a blood sample with the blood-sucking device, which can even predict horoscopes. The teacher is nervous that he has left his glasses in the room, but he's not worried about that. He just wants to see what's wrong with the school. He also wants to know if zhugong will be able to make it back in time for the open house the next day. He doesn't care if he'll make it, because it's part of his job as a teacher to know students' names. He's also not worried if s/he's the only one who's possessed by an evil spirit. He wants to find out if this guy is the same as the evil spirit that's been haunting him all this time. He asks the teacher if he thinks that'll be the case, and the teacher says that he thinks it will be. He then asks if the teacher can leave the hospital and go back to school.
