Yun Yeqing was originally a crazy Taoist priest in the mountains. He drank dew and swallowed talismans and had no regard for destiny. However, he was plotted by the heaven to deprive him of three hundred years of life and his soul was as cracked as a broken candle. Instead of crying or kneeling, he laughed loudly, raised his sword and stepped through the nine heavenly gates, chopped the bones of immortals and burned the books of gods, vowing to let the gods taste the feeling of having their life taken away from them. Chu Jin, once the ancient evil spirit that he had sealed with his own hands, has now become the only immortal sword in his hand. When the god trembled and whispered, "You are no longer a human being," Yun Yeqing opened his clothes, revealing the evil heart beating in his chest: "I am no longer a human being - you are the ghost who forced me out." Chu Jin chuckled: "Then I will accompany you and slaughter him until the end of the world."
