The doctor explains that he was about to go into the bathroom when he saw an assassin hiding something in her hand. He was worried that something bad would happen to the doctor, so he kept an eye on the assassin all the time. They searched the entire plane, but did not find the assassin. The doctor decides to protect him in order to keep the assassin away from the hole in the wall. He finally comes up with a "formula" that he has seen before. He tells the doctor to get some rest. He has not closed his eyes for two days. He is sure that the assassin is the son of the couple. He asks the captain to send the doctor off to his destination. The captain says that they suspected that there was a group of yanxia people in the research institute working with foreigners to acquire some technology from the research center. The group is composed of "level 8 martial warriors" and the doctor is a "level 9 martial warrior". The captain tells the group that they should kill all the foreigners who would help foreigners kill the people in their own country for money. They should kill them all. He says that the people who should be killed are the animals that betrayed their people and country for many years. He adds that the man who killed the master was a "half-step master" and that he died with only one hit kill. He wonders why the chief has asked him to hide his identity and power.
