The young swordsman **Lin Zhiyu** was born in the mountains and had no intention of entering the world. However, he accidentally got involved in the life and death struggle in the Broken Soul Picture after rescuing an injured cold-clothed woman named **Bai Shuangning**. The woman treated him as if she were away from him, saving his life and fortifying him. The broken jade on his chest seemed to coincide with the legendary pattern.
In the snow-covered Jiuqu Mountains, the unpredictable "Lost Soul Valley", and the Dongyue Sword Competition where the iron horse rides on the moon, Lin Zhiyu encounters three completely different women one after another - the cold and arrogant Bai Shuangning, the quiet and gentle Liu Qinghua, and the passionate and straightforward Hongxiu'er - each of them seems to be harboring ulterior secrets; while various sects, hidden masters, and strangers from all over the world are also secretly competing for the soul-breaking plot.
In the flash of swords, true love and betrayal are intertwined, and trust and suspicion coexist. While Lin Zhiyu was searching for the true solution to the soul-breaking diagram, he was making difficult choices in the emotional whirlpool on the tip of the knife.
However, when the picture of a broken soul woven with bloody threads was completely unfolded in the snowy night - he discovered that this was not only the secret of the world, but also the final mystery of his life experience...
