In ancient times, when Huangdi Xuanyuan's golden sword was produced, there were still raw materials left. Due to the high temperature, the still liquid casting raw materials spontaneously flowed to the bottom of the furnace and formed a knife shape after cooling. Huang Di believed that his spontaneous sword intention was too strong and could backfire on the wielder. The Yellow Emperor was afraid that the sword would be lost in the world, and wanted to destroy it with the Xuanyuan Sword. Unexpectedly, the sword turned into a red cloud magpie in his hand, and turned into a burst of red and disappeared into the clouds.
