Li tells the headmaster that the ten evil organizations have existed at the school for a long time, and that he has already lost the opportunity of victory by taking advantage of the school's lax discipline. He then launches into a tirade against the school, accusing the headmaster of being a "scumbag" and a "master of school discipline." He then reveals that the secret of the "slumbag" is that it prevents parents from knowing the children's school grades. He has just found out that his son's grades are as high as ten, and therefore, the sound of the guitar has no bearing on the boy. He also reveals that in the past three years, he has been stopped by "the scum ninja," who has prevented him from finding out about the students' grades. Now, he says, it is their turn to protect him.
