Dragon Vein

This is an Eastern version of A Song of Ice and Fire set in an imaginary world. "Dragon Vein" is not a theory of Feng Shui, but a real vein flowing underground and supporting the aura of the world. The rise and fall of dynasties and the prosperity and decline of martial arts are all closely related to the strength and flow of dragon veins. However, the dragon's veins are drying up. The entire world is sliding towards an irreversible end of the law.
