On the day when the calamity broke his bones, Yun Jiu knelt in the blood thunder and watched helplessly as Shen Zhe pulled away his spine inch by inch and said, "You deserve to die." Three years later, Yun Jiu reappeared wearing demon bones, full of evil aura, but he could only recognize Shen Zhe. He laughed like crazy, and the sword broke in his hand and blood dripped: "You take my bones, and I will eat your soul - you can't escape in this life." The cold blade in Shen Zhe's hand was still there, but the snow that had not melted for thousands of years was hidden in his eyes. The Immortal Sect is chasing after them, the Demon Realm is resurrected, and the Heavenly Dao is shattered. The blood debt between them has long been beyond just grudges.
