"Using the mind control technique when he tries to control the mind of that dark human he will find that two strange spiritual energies are also present inside the body of that person.
Naturally the first one is the dark spiritual energy and the second one is the mysterious spiritual energy that mostly you are very familiar with. I think everyone of you still remembers about the Red moon incident and everyone of you already knows about the red spiritual energy and when those Abyss humans try to capture those Monsters who got infected by the Red spiritual energy.
Actually we found similar spiritual energy inside the body of those dark humans and we give it the name berserker spiritual energy. This spiritual energy naturally boosts your overall power but at the same time it also makes you more wild and also controls your mind.
