In the Netherworld, where "cutting off love and desire" is advocated, the talented swordsman Can Xin, in order to reach the pinnacle of ruthless swordsmanship, uses a secret method to cut off his seven emotions and turn them into cold crystals to seal them. Cutting off love and hate, and forgetting joy and sorrow, his swordsmanship has become increasingly divine, and he is about to usher in the legendary "Selfless Sword Realm". However, on the eve of climbing the peak, a strange spiritual body followed him like a shadow. It was invisible and had no substance, and the sword energy passed through him but was unscathed. This is actually the embodiment of vengeance condensed from all the forgotten emotions and resentments that Canshin chopped off with his own hands!
