In another Martial World, there were three notorious forbidden skills that allowed the wielder to absorb another's power.
The first was North Divine Skill.
The advantage of this skill was that the stronger the user's own power, the stronger the absorption, and the absorbed internal power could automatically be converted into North Divine Qi, thus there was no worry about losing control and going berserk.
However, the disadvantage was that if the power of the person being absorbed was stronger than oneself, it would lead to a perilous situation where their dantian (energy center) could be destroyed, like a river being overwhelmed by the sea.
In fact, how powerful North Divine Skill was had never been fully demonstrated.
The complete North Divine Skill consisted of thirty-six exercise routes, while Duan Yu only learned two of them!
The second was Absorbing Star Great Method.
