Emperor Ming of the Han Dynasty bestowed upon Ban Chao, a descendant of the historian, the bronze swallow talisman and asked him to go on a mission to the western regions to find the method of immortality and the golden Buddha in his dream. Ban Chao searched for the master hiding in the capital, and thirty-six people, including the descendants of the Mo family, the descendants of the pirates, and master Yelang Gu, were traveling with him. In addition to fulfilling the emperor's wish, he also wanted to discover the family origins of the historian and the assassin who framed his father.
