Ren He found it very interesting. Many bullying incidents in school actually had no real cause; it was just a group of kids who disliked someone or found someone to be an easy target. Then that kid would naturally become the one who got picked on.

Sun Yu thought for a moment and then laughed, "We are here to accompany Zhang Ke to the competition. What about you?"
