The strongest person in the novel "Celebrating Years" was Wu Zhu. Wu Zhu was a robot. His martial arts skills were unfathomable, and he was an envoy sent by the Temple. He was once Ye Qingmei's servant and was loyal to her. Later, he became Fan Xian's guardian. In the novel, he had shown his powerful strength many times. For example, in his battle with Ku He, one of the Four Great Grandmasters, he had easily defeated Ku He, and in his battle with the Qing Emperor, although he had been seriously injured, he had still been able to escape.
