The Wude (Mandarin Chinese: 武德 wǔdé) are four aspects that any Martial Artist of true virtue should know. In order for Ryo to meet with Lishao Tao he must learn the four Wude. It is said that those without the Wude often stray from the right path and are hated by others, sometimes killed. Xiuying comments when she first meets Ryo that he only posses Gon and Dan.
- Gon - Everyday, without neglect, to keep training
- Dan - Be brave and stay calm to make the right decision
- Jie - Judge yourself without conceit and do not show moves thoughtlessly
- Yi - To act without hesitation, to do what is right
