Demon bones are the bones of demon beasts.
As soon as Feng Miao opened her eyes, she realized that her spine had been taken away. Fortunately, she met an old man who was proficient in the art of bone replacement, and the old man was willing to replace her bones with his own hands.
Ordinary bone replacement is bearable, but what Feng Miao replaced was the bone of an ancient monster.
The old man is a demon bone master that has not been seen in the world for thousands of years.
It is difficult for demon bones and human bodies to be compatible.
But those who successfully change their bones are all geniuses.
