Qianlong's "Nine Dragon Sword" really existed and was buried in his Yuling Tomb. According to statistics, since the "Great Thief of Tanglin" Sun Dianying excavated Yuling and stole the Nine Dragon Sword, it seems that no one who has come into contact with this sword has a good end.
Qianlong's "Nine Dragon Sword" originated when and where, and by whom it was forged, it is impossible to examine, the only thing that can be verified is that this sword was one of Qianlong's favorites before his death, and was buried with him in Yuling, and was stolen by sun Dianying, the "Great Thief of Tanglin", and returned to the human world.
Until 1939, Sun Dianying handed the "Nine Dragon Sword" to Dai Kasa and asked him to send it to Chiang Kai-shek. Dai Kasa temporarily handed the sword to Ma Hansan of the Beiping Station of the Military Command, who knew that the Resistance Was blocked, who Dai Kasa had never had the opportunity to get the "Nine Dragon Sword" since then. Because in early 1940, MaHanshan was captured by the Japanese in Peiping, Mahanshan then gave up his sword, and the "Nine Dragon Sword" fell into the hands of Yoshiko Kawashima.
Later, it fell into the hands of Dai Kasa, and on the way from Qingdao to Nanjing with the Nine Dragon Sword, he inexplicably crashed. By the time the military commander Retrieved the sword from the peasants, the scabbard and hilt had all been burned. Later, Shen Drunken sealed the sword and the remains of Dai Kasa into a coffin and buried them in a grave.
