The aftereffects of a nightmare are indeed terrifying; assimilation is deadly, and there's no solution to it.
Lin Feng's efforts to enhance his power and his attempts to absorb soul skills might all ultimately be claimed by the nightmare.
This is why, despite its intelligence, the nightmare is still willing to assist Lin Feng in absorbing soul skills.
Because in the nightmare's view, this body will eventually belong to it.
It's helping itself, not anyone else.
Lin Feng understands the horrors of assimilation, but the benefits are indeed irresistible.
There are hundreds of types of demon spirits, each with different abilities; flying, burrowing, ever-changing, and some unheard of, but none are known to assist in absorbing soul skills or increase the success rate of absorption.
A good soul skill is sometimes more important to a demon spirit master than the grade of their lifebound demon spirit.
A good soul skill can transform an ordinary demon spirit master.
