After fusing with the second evil creature, Su Mu felt his body weaken.
This green eye had sucked away a lot of life force and blood essence from his body.
This was what would happen after fusing with an evil object.
Therefore, most of the evil cult warriors were thin and weak, or even shriveled.
Compared to the people of this world, Su Mu was quite strong, but he still couldn't withstand it after reaching the second step.
When ordinary people encountered such a situation, they would either let it go or be afraid.
But Su Mu was different.
He couldn't help but think about the deeper logic behind this.
The evil cultivators were completely different from the martial artists and Qi Practitioners.
The power of a heretic warrior came from external objects. By fusing with non-living heretic objects, they obtained all kinds of strange powers.
Due to his ordinary body, there was a huge difference in power level between him and the evil creature.
