Infinite Evolution: My Idle Evolution System-Chapter 420: Transcendent Class Slayer, The One Everyone Fears...

Sometime during Cassius and the Soul Emperors' fighting period, a crack suddenly formed in the skies above the Motherland. Yet it wasn't the Soul Eaters that were invading…

"I, Nightmare King Drakon, have descended! And with my power, I shall make the puny humans of this world bend to my will—"

SHA!

SPLAT!

A stray energy arc from the battle between Cassius and the Soul Emperors instantly killed the Nightmare King. And as it so happened, this energy arc was produced by Cassius, meaning that all obtained Nightmare Essence was his.

The system notifications rang out continuously, informing him of all the power-ups he just accidentally received…

*Ding!*

[You have slain a Low-rank Nightmare King that possessed cultivation exceeding the 9th Nightmare Rank!]

[Your Nightmare Essence Gauge has skyrocketed!]

[Nightmare Slayer Cultivation (7th Stage 2nd Class) → (Low-Rank Transcendent Class)]

[Your 'Nightmare Core' begins to take shape as a result of your breakthrough into the 1st Class Slayer Rank!]

[Your formed Nightmare Cores take on the qualities of Death, Destruction, and Origin. As long as these aspects are present in the world around you, even death will not be enough to fully kill you.]

[As a result of your breakthrough into the Transcendent Class, your 'Nightmare Source' begins to materialize. With it, even if you perish in the Land of Beginnings, revival is possible in the Nightmarescape.] frёewebnoѵēl.com

[All of your Nightmare-related aspects received a major upgrade!]

['Mora'—your Slayer Weapon—has begun to evolve!]

OOOM!

['Mora' has become fully sentient, following the lead of 'Lilith,' your Primary Growth Weapon!]

Cassius felt the powers of Mora tremendously increase. Just a single one of her slashes was now dozens of times stronger than before.

"This should make things more fun," he mused while wildly swinging Lilith and Mora around, effortlessly pushing back all of the Soul Emperors. "But you lot are still holding back."

"He wants us to go all out??" Soul Emperor Nightveil couldn't believe his ears. "Is he insane!? Even the strongest of the Nightmare Emperors cannot restrain us if we do that!"

Because they lost all sense of reason whenever they unleashed the full extent of their Soul Source Power, they planned to die without going that far. Let alone the impact it had on them—doing something so reckless could very well have them slaughtering the one they wanted to kill them.

"You suicidal idiots can do whatever the hell you want!" Soul Emperor Megora cursed. "Just know that I won't be taking the same self-destructive paths as you. I just wanted to have a good fight, not a battle to the death!"

The other Soul Emperors were hesitant.

But without hesitation, Soul Emperor Salar ignited his Soul Source!

RUMBLE—!

His body rapidly expanded, with horns and spikes growing all over him. His skin tone turned darker, his teeth larger and whiter, and his aura a hundred times greater than what it was before.

All of the Motherland experienced extreme dread over the release of a true Monster…!

"This crazy bastard…"

Soul Emperor Megora had never met anyone as eager to die as Soul Emperor Salar!

It was mental!!

"Since Salar has fully committed, I might as well do the same," said the Unnamed Soul Emperor as he followed suit with the ignition of his Soul Source. "This is farewell, old friends. Let there not be a next life."

OOOM!

They watched as the Unnamed Soul Emperor transformed in a similar way as Soul Emperor Salar. And seeing as how they already came this far, the other Soul Emperors did the same.

Only one bowed out at the last second, joining Soul Emperor Megora and the other non-suicidal Soul Emperors in the bleachers.

They, along with everyone in the Motherland, witnessed something completely out of this world that day. Pushing away the heavens and the earth with physical bodies overflowing with astronomical levels of power, the Mindless Soul Emperors shattered space and time without even trying.

"ROOOARRGGHH!!!"

They roared to the Cosmos, forcing trillions to cover their ears. Ripples of power rolled out in shockwaves, knocking countless off their feet.

"Things have become very dangerous," said Arthur Pendragon as he constantly made signs with his hands. "I'll give young Cassius a chance to overcome this huge hurdle, but the exact moment I determine him incapable of doing that, I'll have to step in."

Arthur Pendragon wanted him to win, but in the end, the prodigy was still young.

Whereas the Soul Emperors were millions of years old, having accumulated enough power to each be capable of wiping out the Land of Beginnings…

As one man withstood the combined powers of over a dozen full-powered Soul Emperors, numerous shadowy figures in another World noticed this disturbance.

Within the Nightmarescape, in the Dark Evergreen Empire, a large, scary-looking figure turned his head in the direction of the Land of Beginnings. This figure was known as Nightmare Emperor Evergreen, and was one of the most powerful and ancient of the Nightmare Emperors.

He had been around since before the Great Eclipse, coming from the same generation as the Terrors sealed within the Boundless Gorge. In fact, he was one of the main figures responsible for locking away those Terrors and plenty of others that reigned prior to the Great Eclipse.

Nightmare Emperor Evergreen was also the one who ordered his subordinates to send out the 'Dogs' that once brought the Mistalore Defense Nation and many others to their knees.

"The Soul Emperors are making a move in the Land of Beginnings? Are they finally trying to take down that old fossil??" Nightmare Emperor Evergreen's brows furrowed deeply. "No, that doesn't seem like something they'd do…"

The forces of the Netherworld knew just as well as the Nightmarescape of just how much power Arthur Pendragon wielded.

If not for the Laws of Reality preventing him from doing so, it was very likely that Arthur could erase all 3 Major Worlds with a single swipe of his hand…

"That is the Arthur Pendragon everyone fears," said Nightmare Emperor Evergreen, his thoughts stirring. "But what if he's… injured…?"

The likelihood was extremely low. Very, very low.

But there was no other reason that could be used to explain why so many Soul Emperors unleashed their full power in the Land of Beginnings.
