The position of the Headmaster of the Zephyr Academy, had always been passed down from father to son.
The previous Headmaster of the Zephyr Academy was the Master of Fan Qi and Ning Rui. Their Master had no offsprings and he had handed down his position as Headmaster to his disciple, Fan Qi.
According to tradition, if Fan Zhuo remains alive, Fan Qi would be able to relinquish his Headmaster's position to Fan Zhuo. But if Fan Zhuo were to die, the fact remains that Fan Jin is only an adopted child. However, Fan Jin's exceedingly high popularity in the Zephyr Academy might just be able to push him up to legitimately succeed the position.
For Ning Rui to assume the position, he would have to get rid of the two sons of Fan Qi's before it would be possible.
Seeing through her father's intentions, Ning Xin was naturally happy to lend a hand to make it possible.
