'Skilled Mercenaries, and a high number of Slaves…'
That was the first thing Nial realized when he burst through the black Miasma without any hesitation.
The moment the black miasma was released from the darkness ball, the majority of guards panicked for a second.
They changed their positions and stopped with their charge at once. Noticing the change in their own rows, the more experienced Guards had to stop as well. Without wasting a moment, they released various abilities to dispel the black miasma and make use of it at the same time.
It was not only their sight that had been restricted by the black miasma, after all!
The long-range attacks the Guards had released with a great precision cut through the black Miasma, yet, no screams of unbearable pain resounded through the entrance hall of the hidden laboratory.
To their disbelief, the most dangerous long-range attacks had been destroyed by some unknown power, baffling even the experienced Guards, who knew just how strong one had to be in order to obliterate one of the attacks they had released.
What they didn't know was that Nial had used Chaos to work as per his will and break the long-range attacks, which would have reached several Nightshadow Elves.
'They would have survived, but the safe route is still the best.'
No casualties, or at the most having severely injured Originals on their side would be the best outcome. Nial might be able to scan, visualize and perceive everything that happened in the entrance hall and the hallways around him, but his mana sense and range of perception were still restricted in certain areas.
The entire hidden laboratory was not a place where someone with his needs to perceive his surroundings was supposed to be.
But that was the misfortune of the hidden laboratory's guards rather than his own.
He could visualize his immediate surroundings perfectly which was exactly what Nial made use of. His dark energy spread through the ground toward all guards whose shadows quickly disappeared under the cover of the abyss-like darkness of his dark energy.
A small smile appeared on Nial's face as he ducked under a compressed mana blade that released a mighty crescent-shaped beam. He leaned forward, and his upper body nearly touched the ground. Mana merged with a crimson bloodline that circulated through his body, enhancing his speed drastically.
The sudden spurt in his agility allowed Nial to appear in front of the closest guard. The guard, who was probably a lizardman, or a being of some other race with similar genetics, slashed at Nial but his movements were weak and sluggish.
Despite being at the Deux rank, the lizardman guard was not adept at fighting. He was a mere slave who was forced to obey his masters and protect the hidden laboratory. Under normal circumstances, guarding this place wouldn't be a problem for him. Nobody knew about the location of the laboratory and it would be foolish to attack it.
The Shelturion had installed various traps at the entrance doors and in every hallway a long time ago, and then there were the truly powerful and veteran fighters, the mercenaries.
But despite all of the safety mechanisms in place an attack was happening, just now, right in front of the lizardman's eyes.
The guarding slave's eyes were locked on the terrifying ruby eyes that stared at him through the eternal darkness that shrouded the living being, if the being in front of him was even alive, to begin with.
He tried to activate one of his abilities to push the perpetrator away, but it was already too late. He felt a sting in his chest and neck, his sight blurred and he lost the strength to hold his sword. The Lizardman's legs gave in and he collapsed on the ground, his body unable to heed the commands of his mind.
His body twitched a few times while a pool of dark red blood formed on the white marble that was now coated in the color of the abyss.
Meanwhile, his attacker had already disappeared, the blood on his daggers' blade splattering to his side as the daggers vanished into thin air once again.
The grimace that had formed on Kaeldur's face turned even more devilish than before and he shot forward once again. His speed increased further and he made use of the dark energy on the floor all around him.
Chains weaved with precise control and willpower and emerged from the ground. They were pitch-black in color and exuded eerie dark currents that filled the surroundings with heavy tension.
However, neither Nial nor the Nightshadow Slaves seemed to be affected by the heavy tension. Their focus was only on Nial's chains of darkness that had burst forth and coiled around the necks of the guards restricting their movement, even if it was just for a moment.
Nial had created one chain for every guard in the entrance hall of the hidden laboratory. It required a tremendous amount of dark energy to be utilized but that was worth it. He couldn't be stingy with his dark energy consumption, especially since the dark energy accumulated within his Heart of Darkness didn't feel less after his creation of dozens of chains.
The Heart of Darkness was an endless pit of dark energy and Nial had access to it. That was exceptional and exactly what he needed when pushing forward.
Restricted by the dark chains that shocked them, the guards reacted very differently. Some unleashed their mana and attacked the dark chains with the use of their mana, while others made a twist to cut through the dark chains with their razor-sharp Runic weapon.
As for the others, there were two or three guards that used their brute force to break the darkness chains, while the remaining guards, all of which were slaves, panicked even more than before.
The skilled mercenaries were just about to shout out loud and tell the slaves to regain their composure and make sure that nobody would be able to push past them when a terrifying sight unfolded in front of them.
More than ten Nightshadow Elves emerged seemingly out of nowhere. Some used Shadow Steps to step through the shadows and emerge behind the Guards, while others were focused on distracting everyone, and pulling everyone's attention onto them.
This was done in a rather simple manner with the creation of hundreds of shadow spears. Nial gave them a helping hand by willing the darkness in the ground to pierce spikes out of the ground's surface.
At the same time, Nial didn't stop his assault. He was not an Original, who focused on long-distance fights. Nial would rather enter close combat.
And that was exactly what he did just a moment later. Kaeldur's claws were spread outward and they began to move in sync with his original arms.
Nial turned into a black flash all of a sudden as he burst to his right. All of a sudden, it looked like he was sinking into the ground, which was exactly what happened.
He merged with the dark energy in the ground and emerged somewhere else just a moment later.
As he moved rapidly, his four arms turned into the instruments of a massacre. His dagger and Kaeldur desired the warmth of blood on their body and Nial would be the last one to reject their wishes.
He slashed the daggers through the small slits between the guard's neck and his helmet. A pained groan and a shriek of desperation followed just a moment later before blood gushed out of the small slit.
At the same time, Kaeldur's claws ripped through the low-quality runic armor. Kaeldur's arms pierced through them with ease, causing devastating damage to the Original they had attacked, and crushing the fighting morale of the guards all around them.
While Nial's fighting style and appearance were already grotesque enough to instill fear in the guards, the Tyrant of Destruction made things far worse.
Tyrant's mace was brutally spun in all directions, smashing the heads and bodies of the guards around him. At the first glance, it may look like he was fighting without a plan in mind, but the veteran mercenaries realized that the opposite was the case.
The Tyrant of Destruction might be considered a blockhead, someone who had only muscles and no brain, but he was actually very versatile and cunning when it came to fighting techniques.
Even Nial didn't know the true extent of Tyrant's power because his second Devil never exposed everything.
As for the current situation, Tyrant had yet to sustain an injury because nobody dared to get too close to him.
He inflicted fear and terror in the minds of his opponents while killing those in a certain range around him with brute force and immense brutality!
That was his mantra for today!
