Twenty years ago, Zi Xuanjian was a big demon who frightened the martial arts world. Yun Yi, the "Jade Flute Master" known as the "No. 1 Sword in the Central Plains", was entrusted by righteous people in the martial arts to go to Maoshan to surrender the demon. They both fell into a deep valley, their life and death unknown. The Wulin then returned to its former tranquility. Ten years later, a storm broke out in the martial arts world, and there were rumors that Zi Hyun had reappeared. However, not long after, the waves seemed to have receded.
Yunmeng and his junior brother went to Yishan to meet Master Xu as usual, but they were shocked to hear a huge secret. They returned to Yunshan with a sword that had been forged for ten years to say goodbye to their master and enter the world for the first time. Not long after they came down from the mountain, they met a master who called himself Zi Xuan Sword. They tracked him down, but they also led to several connections.
Where is the Zi Xuan sword? What was the reason for her making trouble ten years ago? How many Zixuan swords are there in Jianghu? The constant occurrence of tragedies in the world prompted the four brothers to determine to find the sword manual to crack the "Feng Yue Palm".
