According to official website's query, the blade of the Qingfeng-xiangguang fracture in the anime work "The Shadow of 567 Destiny" is called Shuangxiong, which comes from a forging country and has strong attack power. Qingfeng once killed the Iron Hand Dragon with the two males, which is enough to see the strength of the two males.

2. The domestic animation "Wu's Shadow Destiny" tells the story of Wu's return to Xuanwu to find his life experience, which led to the pursuit of seven shadow assassins. Their purposes were different and their past was different, and the plot of Qingfeng also surfaced here.
