There was no clear ranking of Fan Xian's martial strength in the show. In " Joy of Life," Fan Xian was a growing character. From a young age, he had received the training of Uncle Wu Zhu and old senior Fei Jie. This allowed him to grow up in the countryside, and his martial strength was already capable of killing an eighth-level master. However, Fan Xian had yet to fully grasp the Tyrannical zhenqi, so his martial prowess could not be compared to a ninth-level ace. In addition, Fan Xian was also very intelligent. He could scheme against the enemy, but he was still at a disadvantage in his confrontation with Chen Pingping and the Qing Emperor. Therefore, Fan Xian needed to continue working hard to improve his martial strength and intelligence to ensure his survival and development. In general, Fan Xian's martial strength was an existence with unlimited potential in the show, but it was still impossible to determine the exact ranking.
