Fan Zhuo's health had always been frail and Fan Jin as the "adopted" son had nevertheless always still been treated no different by Fan Qi, just like he did, with his "biological" son.
If things had continued on as per status quo, Fan Zhuo's ill health would most probably not allow his body to take much more of the toil and expire, which made everyone expect the esteemed position of Headmaster to irrefutably fall right into Fan Jin's lap next.
But an unexpected problem came into the picture with Fan Zhuo's health.
Under Jun Wu Xie's treatment, Fan Zhuo's health gradually began to improve. Fan Zhuo, who had not even been fit enough to step out of the academy had in the recent period, gone out of the Zephyr Academy two times. Judging from Fan Zhuo's actions, the people in the Zephyr Academy could clearly see that the youth who had been frail and sickly since young, was slowing recovering from his ailments.
