The dispute between Jianghu and Jianghu started from a legendary "edgeless sword". This sword has no edge, but it hides a century-old secret of the Bai family. It has attracted Lengyue Villa, Silver Sword Villa, the Dark Gate and various factions to fight for it. The alcoholic swordsman Shangguan Wuying is carefree and unrestrained, but due to a conspiracy, he is involved in the whirlpool, and starts a wise and courageous confrontation with Bai Yibo, the owner of Silver Sword Villa, and Leng Qiuya, the owner of Lengyue Villa.
Bai Yibo, who was responsible for the annihilation of his family, was famous for his "sword falling snow", but was revealed to be the leader of the Dark Gate; Leng Qiuya, who appeared to be elegant, was actually Long Qiyun, an orphan from Nanzhao, who had planned for twenty years only to restore the country. The mystery of Leng Shuang'er's life experience is actually the key to uncovering the second layer of the "Edgeless Sword". When the "Tongtian Pill" and the evil power "Blocking Technique" appeared in the world, the world was plunged into a bloody storm. Due to the backlash of his power, Bai Yibo fell into the devil's path. In the end, he regained his consciousness at the sacrifice of his sister Leng Shuang'er and converted to Buddhism to atone for his sins.
The story uses the flash of swords and shadows as the scene, depicting the friendship between brother and sister, the grudges between family and country, and the struggle of human nature. Shangguan Wuying's chicness, Bai Yibo's forbearance, and Leng Shuang'er's purity are intertwined into a picture of all living beings in the world. When the full moon hangs high and the broken sword is reforged, behind the truth and price, only blood and wine bear witness to the knight's final destination.
Purpose: The novel reveals the corruption of human nature by power and desire through the disputes between rivers and lakes caused by the "edgeless sword". Bai Yibo fell from an avenger to the devil, Leng Shuang'er exchanged his life for his sobriety, and finally converted to Buddhism, showing the individual's struggle between sin and redemption. The work criticizes the blindness of the pursuit of power, emphasizes the significance of family affection and sacrifice for the purification of the soul, and implies that the rivers and lakes are ultimately the Shura field of good and evil in human nature.
