In this short scene, we are introduced to a new character named "Yang," who is the substitute teacher for the students in the Chemistry class. He tells the students that they are not allowed to do anything that is not related to the class, and that they should get up and stand outside for the lesson. He says that he just knew that "brother zhan" was a real man and that the annihilation master had turned pale. He asks the students why they are slacking off and tells them that he is not sure that they were right about him. He explains that he has already forgiven him, but that someone accidentally splashed water on his painting and accidentally landed it on his brush. The students are confused, and he asks his brother sheng to come over and help him.
