Yun Duanya's sword broke his bones, his blood was stained by the cold front, and he was abandoned by everyone in the world like a pair of worn shoes. But he swallowed Liu Guqing's true bone marrow seed in the ruins. From then on, he hid thousands of bones in his body as a sword, and the mountains and rivers were torn apart in anger. There are rumors in the world that he is no longer a human being, but a walking mountain of corpses and a sea of blood. And Liu Guqing, who was originally the coldest bone doctor in the world, cut his seven tendons to save him and scattered his soul into medicine. Instead, he swallowed it into his body. His soul was placed in the sword bone, whispering day and night: "You swallow me, and I will swallow you." One is a broken body, the other is a lonely soul. They hold a sword together, cut off the hypocrisy of the righteous way, drink up the blood of the Demon Sect, and finally become a world where broken bones are turned into bones and the sky is swallowed up by the sword.
