Xu Zhu of the Eight Divisions of Heavenly Dragons is a fictional character whose kung fu level cannot be accurately described. In the novel, Xu Zhu was originally a young monk without any martial arts, but later, through a series of experiences and cultivation, he obtained a certain level of martial arts cultivation. In his later years, Xuzhu had become an expert in martial arts, and could easily deal with all kinds of martial arts challenges. However, his martial arts level was not clearly stated because the novel did not give enough details to describe his martial arts system and the types of martial arts he learned. Therefore, Xuzhu's martial arts level could be varied and could not be measured with a simple standard.
