The monk tells the others that the "dragon soul" of the ley line belongs to the royal family, and that they must guard it lest it spread throughout the world. The monk explains that the duty of monarchs was to prevent "the dragon veins" from "ravaging the world" once the seal of seal was broken. For thousands of years, the dragon soul could not be tamed, and the only emperor who could tame it was the current emperor of huangpu, who chose to be the master of the soul.
