"I made the judgment based on my student, Xuanyuan Po. His body constitution is the strongest among the students I've ever seen."
Sun Mo wasn't bragging.
The closest comparison to Xuanyuan Po would be Zhang Yanzong. When Sun Mo first joined the school, Zhang Yanzong was publicly acknowledged as the strongest person in his batch. Even An Xinhui picked him as the student leader for the last league tournament.
Zhang Yanzong's body constitution could be considered within the top three among the students participating in the student battle. But when compared to Xuanyuan Po, he was just a little brother.
He was at least a level lower.
One must know that Xuanyuan Po was still in his youth. After he matured, it was unknown how powerful he would become.
However, why was Zhang Yanzong able to become the group leader?
