"I have a sword to cleanse the world."
For ordinary people, the older their bones are, the more porous their bones are. However, for practitioners, the older their bones are, the stronger their cultivation is. If they don't want to practice hard, they can still attract others.
The Bone Age Sword is the most powerful magic weapon in the world that absorbs other people's cultivation and increases one's own bone age.
It has been lost for 30,000 years.
The first few chapters are very touching.
