Disciple Shen Duanfeng's meridians were all broken and he was expelled from the sect. However, he swallowed the resentment of thousands of swords in the ancient battlefield, went crazy and refined his body, and killed all the masters in the world with one sword. He is as silent as iron, but he inspires the saint Yun Nishang to secretly help him, the sword-making madman Chihou Old Ghost rebuilds the broken sword for him, and the betrayal of the supervisor Chu Wumian and the secret of the bloodline of the blind boy Little Mute are gradually revealing the truth about the collapse of the ancient swordsmanship. The sword is not a sharp weapon, but blood and bones; the Tao is unorthodox, but unyielding.
