Back at the school, the doctor tells the teacher that he's all right, and he'll be back later. The doctor asks if the teacher is awake, and the teacher says he is. He tells the doctor that he almost lost the fight with xiaoshan, but he fought with him anyway. He blames himself for not coming sooner to save the teacher. He says that if he had found the teacher sooner, he could have saved the teacher, but even if he did find the teacher earlier, how could he guess that the man was the man who was going to the research lab? If there was no info from the teacher's classmate how could the teacher guess correctly that he was going there? The doctor says that it's his fault that he didn't arrive sooner, because he was careless and stupid. He also says that the second master tricked the man into the trap as planned, and that he blew the whole system up. He's okay not because the man showed mercy, but because he knocked the doctor out. The teacher asks the doctor if he has information on the man he asked him to investigate. The man's name is chao lin, and his name is exactly the same as the doctor's. They look exactly alike, except for their hair, which is shorter. They also look exactly like each other, except that their eyes are agile and they both look like they're scheming. They're both scheming, but their faces are thinner. The father asks the teacher if he knows about the three gang. He asks if they have a relationship with the three men, and if they've put him on their side.
