"Mark of the Seven Sins: Domain of Wrath!"

A dome-shaped mana layer, made of the same otherworldly mana pulse that was released earlier, was birthed into existence around Eren. At the same time, Eren's appearance started changing into his new-normal form. His hair turned white and his eyes turned red. Plus, the runic inscriptions on his body which looked like abstract tattoos started spreading over his torso and limbs.

The red-tinted mana layer started spreading further under Eren's guidance. It soon encountered the array-generated mana layer. The layers seemed to have a conflicting presence with each other. Finally, the red-tinted mana layer managed to override the array-generated mana layer before spreading past it.

The mana-dome covered where the two rangers positioned on opposite sides of the battlefield were located. It only stopped growing further when it included distant enemies. The runes started floating over the dome's surfaces as soon as it was stabilized. It separated the environment inside the dome from the world outside.

Kelmar and the bowsword ranker, who were too stupefied to react to the dome-shaped mana layer, were finally snapped into reality. They had ominous feelings in their hearts as they watched the mana dome stop only after bringing them inside.

Kelmar was the first to act on his instincts. He tried to run away from the battlefield without worrying about any of his soldiers or Claho's order. He cast his movement spell and tried to breach the mana-dome and reach the other side.

"Aaaargh!"

Kelmar's voice could be heard in the nightly silence. The dome-shaped mana layers had been stretched by the ranger's movements only to throw him back with greater momentum than his approaching speed.

That was not all. Kelmar's skin that had touched the mana-dome began melting on its own. As if he had touched an intense form of mana acid. His hands, the skin on his knees, and some of his face started melting first. Soon, signs of skin melting appeared on other parts of his body.

The front of Kelmar's body soon had no epidermis whatsoever. He looked like his skin had been surgically removed and his red muscles were exposed out in the open.

Kelmar's suffering didn't end there. The red-tinted mana that had come into contact with him through his touch started invading his mana circuits. The mana soon reached his mana core and interacted with it.

The next thing Kelmar felt was his mana core getting imploded from within. The implosion ran through his mana circuits and burned it away too.

Kelmar continued screaming in an attempt to cope with the excruciating pain he was experiencing. His teammates were keeping tabs on him through their stretched mana sense as well. A cold shiver ran through all their spines as they realized the consequences of trying to get away from the battlefield.

Claho was terrified by Eren because he observed the devil gazing directly at him with a smile plastered on his face. His pitiful condition was the stuff of nightmares for him.

So when he observed Kelmar's state with his mana sense and heard his screams, Claho started shivering on his own. His mental state was already affected by the mana pulse that was released a few moments ago. Kelmar's condition only cranked up those feelings of fright to eleven.

But what happened next was even more bizarre. Everyone observed as Kelmar's body started changing post his mana core destruction. He started to appear as something non-human in appearance.

Kelmar was getting consumed by the anger that he felt due to the insurmountable amount of pain he felt. The feeling of "I don't deserve any of this" had made the seed of anger sprout in his head which then bloomed into full-fledged wrath.

Kelmar's body started growing taller as the wrath inside his head started growing. He lost all hair on his head and it began showing signs of deformity. His musculature also appeared to be changing. It now had warts at the most prominent muscle definitions.

Kelmar's epidermis was destroyed by now. His red muscles were getting puffed up as warts over them grew with each passing moment. His left hand also started changing all of a sudden. He lost his palm and his fingers as the radius and ulna bones of his arm fused before becoming a large fang-shaped bone.

Kelmar's muscles grew around the fang bone with rapid but unstable regeneration. The muscle fibres of his body were showing signs of getting torn because of the stress they were feeling.

He had no clothes on. The ranger was completely naked. Yet there was no sexual organ to be found. As a result of his transformation, he became genderless.

"Kyaaaaaaaah!"

Kelmar released an angry scream as his transformation was complete. He stood up and looked at everyone on the battlefield with inhuman-looking eyes.

Kelmar fixed his eyes on the ranker closest to him and released an angry roar at him. The latter didn't understand what was happening at first. But soon he saw the creature that was previously called Kelamr approaching him with threatening momentum.

The guy tried to run away from Kelmar. Kelmar, despite not having the mana core, had become incredibly fast. His speed when he could use mana was nothing compared to what he could achieve with his mere muscles alone. The otherworldly mana temporarily boosted his muscles to an unimaginable level.

The mutant created by Eren's strange ability could not control his actions. That mutated flesh held only a sliver of his previous ego, which was constantly breeding feelings of anger, injustice, and rage toward everyone around him.

'Why didn't you feel the pain? How come you get to be lucky and I don't? Why are you still human and I am not?'

The ego kept on thinking like this as its body attacked the ranker that Kelmar once identified as his teammate. As he approached the man, he used his inhuman physical speed and agility to drive his newly formed fang-shaped bone through his stomach from behind.

"Kiyaaaaah!"

The mutated creature released another scream as it lifted the skewered body of the soldier it had just killed.

AN: Will upload the illustration for the mutant creatures on Instagram and under the chapter comments soon.
