Xie Duanyun broke his sword and entered the rivers and lakes. The long night was stained with blood. He split three sects with one sword, but he laughed crazily that night. The sword cut through the mountains and rivers, and no one dared to approach. Li Qianfeng carried seven broken blades on his back and searched for him through blood, just to ask: "Why don't you kill me?" After ten years of grudges, one thought became a devil, and another thought became a god. The world calls Xie Duanyun a sword madman and Li Qianfeng a sword devil, but they all know that that night the mountains and rivers were broken, not by swords but by heartbreak. Now, one is more crazy and the other is more cold. The day they meet again will be the time when there will be no more swordsmanship in the world.
