- Pronunciation: Dao Pian Ji Hua
To take over the world, the Master (老掌門) of the Ye He Na La family did an experiment to create an army of people and control them with the supreme ring (至尊戒) that can only be worn by the head of the family. The people who were created by this experiment are called "Blade" (刀片).
Like the Stone-Hearted Assassin (石心殺手), they are usually harmless and unaware of their true identities. But when someone uses the supreme ring to activate them, they will become senseless robots and do whatever the wearer tells them to. This conspiracy became a myth to most people, and only the head of the family and those who were involved in the experiment knew the conspiracy's existence. Han and Bing Xin are two of the people who were made in this experiment. After the destruction of the supreme ring, the created people were freed and remained unaware of their true identities.
