Haruji, as the teacher-in-charge, had been conflicted about who to send to the stage for a full 14 minutes. At the last minute, he made his decision.
Fifteen minutes was the maximum time limit.
In the end, Haruji did not send Rankhan on stage.
Rankhan was his last hope of turning the tables in this battle exchange. He was also the only person who had a chance of killing Xu Tui.
Haruji knew very well that it was very, very difficult to achieve both goals at the same time. But at the very least, he had to achieve one. Of course, deep down in his heart, he still had the extravagant hope of achieving both goals.
Haruji chose an Extreme Branch cultivator whose strength should be similar to Zhang Changtai, who was sent by Huaxia. He had a high chance of winning if he fought hard.
However, Haruji had underestimated the fighting spirit and determination of the students from the Huaxia Genetic Evolution College.
