Feng Jue Sword and Han Jue Sword are originally one body. They were transformed from the spirit stone at the top of the Snow Valley in the far north. The Gate of Snow Valley is a barrier that is isolated from the outside world. Because of the years of snowstorms here, people inside can't get out and people outside can't get in. According to legend, only by holding the Feng Jue Sword and the Han Jue Sword, which are of the same lineage, can one avoid the devastation of a blizzard.
Lin Yufeng was originally born from the sword soul of Tongfeng Juejian by taking the essence of heaven and earth. He was picked up by Lin Jue, the master of Jiangnan Yanyu Pavilion, so he was raised. But he was bullied by his brothers in Yanyu Pavilion since he was a child, until an adventure in Fengxiu Valley started his extraordinary journey.
