Did the Top Ten Gu Jian Survive? Where is it now?

There is no sword called "Xuanyuan Sword" in real history, and even the technology of smelting copper in the era of the Yellow Emperor is very low, let alone smelting iron. But in the historical records, it is indeed recorded that the Yellow Emperor had a sword. The Classic of Mountains and Seas and the Second Classic of Zhongshan say that "Kunwu Mountain is full of red copper." And in Wang Jia's "Notes", it is recorded that "Kunwu Mountain is full of red gold and the color is like fire. Yesterday, the Yellow Emperor killed Chiyou, and Chen Bing was here. Digging a hundred feet deep is not as deep as a spring, and it is like a star. Diduo Dan, the stone is copper, and the copper color is green. " However, it didn't mention the name of the sword. Supplement: Longyuan Sword: An ancient famous sword in China, it is a clean and high-spirited sword. The legend was created by two swordsmen, Ou Yezi and Ganjiang. In addition, this sword was once the sword of Tang Gaozu, and was buried with Tang Gaozu in the fairy after his death. It is also said that Tang Gaozu once spread this sword in Li Shimin. When Emperor Taizong was in Tang Dynasty, he was buried with Li Shimin in Zhaoling. Ganjiang and Mo Xie are two famous swordsmen and the names of two famous swords in China, which first appeared in the Spring and Autumn Period. However, so far, neither sword has any archaeological evidence; What metal is used for casting, appearance, weight and other issues can only be glimpsed from ancient books for the time being, or carefully examined according to weapons unearthed at the same time. General and Mo Xie are probably bronze swords of the State of Wu in the Spring and Autumn Period, because the sword of Gou Jian, the King of Yue, unearthed in 1965 and other swords of the same period are bronze swords. On the other hand, according to the biography of wuyue and Lu in the Spring and Autumn Period, the general and Mo Xie are both iron swords. However, Wu Yue Chun Qiu was written in the Eastern Han Dynasty, when the bronze sword was replaced by the iron sword, so it may be recorded incorrectly.
