Compared to 『Seven Deadly Sins』, the Simulated Creation Star Chart 『Hyakki Yagyō』—Night Parade of a Hundred Demons— possessed a completely different kind of authority.
Its power allowed it to forcibly convert the spiritual rank of all races—except yokai—into that of a human.
For most non-human races, the reason for their overwhelming strength lay in their racial talents and innate abilities.
Humans, by comparison, were weak.
But they possessed something unique: potential.
Most non-human races entered the world already equipped with powerful natural abilities and advantages granted by their species. Humans, on the other hand, started weak—but their growth potential was limitless.
Although 『Hyakki Yagyō』 did not explicitly state that converting someone's spiritual rank into that of a human would weaken them…
For a non-human being to suddenly become "human" in essence would almost certainly affect their strength to some degree.
Item Name: Simulated Creation Star Chart — 『Hyakki Yagyō』Item Rank: Transcendent Star-Class (High)
Description:A Simulated Creation Star Chart once wielded by the Human Final Trial "Theory of Yokai."
When the Night Parade of a Hundred Demons marches forth, even gods and demons withdraw in fear.
All races that are not yokai become nothing more than prey.
Effect:Transforms the spiritual rank of all non-yokai races into human rank, stripping them of their original racial talents and innate abilities.
There was a reason Ren had previously believed 『Hyakki Yagyō』 wasn't as powerful as 『Void Star: Tai Sui』.
The system's classification made it obvious.
Tai Sui had been rated "World-Breaking Class (Lower Tier)", while 『Hyakki Yagyō』 was merely "Star-Breaking Class (High Tier)."
Ren estimated that if it were Az-Da-Kaha's legendary Star Chart 『Avesta』, its rank might even surpass Tai Sui.
Still, failing to obtain both Simulated Creation Star Charts left Ren only slightly disappointed.
First, he had become a True Awakened Demon Lord.
Then he had acquired a Simulated Creation Star Chart.
If he kept being greedy after that, it would honestly feel a little shameless.
Right now, his own strength had likely stabilized around the mid-level Transcendent Tier.
With the additional power of a Simulated Creation Star Chart, he could probably hold his own even against a high-level Transcendent Tier opponent.
All he had done was take a trip to the Problem Children world—and his strength had essentially jumped an entire tier.
That level of growth was nothing short of terrifying.
As for this so-called Slime World, Ren still didn't know how powerful the Ten Demon Lords truly were.
But judging from the level of the Orc Disaster they had defeated earlier…
If that was the benchmark, Ren could probably fight a hundred of them alone without breaking a sweat.
"Originally, I should head back to my territory," Ren muttered while looking around the barren wasteland he had awakened in."But getting teleported to the middle of nowhere like this… I can't even figure out where Falmuth is."
After a moment's thought, he shrugged.
"Guess I'll go check on Rimuru first."
Both Shion and Shuna were direct named retainers under him.
Sensing their demonic energy shouldn't be difficult.
The ground beneath Ren's feet exploded into fragments.
His body launched into the sky like a missile.
A moment later, he accelerated forward like a jet fighter, breaking the sound barrier as he shot across the sky.
Meanwhile, in the Great Jura Forest—
Ever since Rimuru and his allies had defeated the Orc Disaster, things had changed drastically.
Rimuru had not only absorbed the defeated Orc Lord's power but had also taken in the surviving one hundred thousand orcs, naming them and transforming them into the Orcish race.
From that moment on, the monsters of the Great Jura Forest had all begun acknowledging Rimuru as their ruler.
Later, alliances were formed with the human kingdom of Falmuth and the dwarven nation Dwargon.
With those alliances established, the region had officially become a nation:
The Monster Federation.
Thanks to Rimuru's knowledge of modern society, the analytical abilities of Great Sage, and the massive labor force provided by the Orcish race, the country had developed at an unbelievable pace.
In just a few short months, the Monster Federation had become more prosperous than many human kingdoms.
But peace never lasted forever.
Because this very morning—
One of the oldest Demon Lords had suddenly arrived.
The Tyrant of Destruction, Demon Lord Milim.
Manipulated by someone behind the scenes, she had appeared directly in Rimuru's city.
If the invading Demon Lord had been Clayman, neither Rimuru nor Benimaru's group would have panicked like this.
But this was Milim.
That was an entirely different story.
The twin-tailed pink-haired girl standing before them looked no older than thirteen or fourteen—a petite, almost doll-like figure.
Yet Benimaru and the others knew the truth.
She was one of the oldest Demon Lords in existence.
And her strength was on a completely different level from someone like Clayman.
Even standing in front of her was terrifying.
Benimaru and Ranga—beings considered high-level monsters by most standards—could barely steady themselves under the sheer pressure of the aura radiating from her body.
Even Rimuru, who had devoured the Orc Disaster, possessed a Demon Lord Seed, and housed the legendary Storm Dragon Veldora within him…
Even he stared at Milim with a grave expression.
Moments earlier, Rimuru had used Great Sage to analyze her.
The results had nearly crushed his spirit.
According to Great Sage's calculations, the amount of magicules emanating from Milim's body was at least ten times greater than his own.
In a conventional battle, his chances of winning were—
0.0001%.
In other words…
Practically zero.
Benimaru and the others understood the overwhelming gap in strength.
So they immediately proposed a desperate plan: they would hold Milim back while Rimuru escaped.
Unfortunately—
Benimaru's Hellflame Prison,Ranga's Black Storm Tempest,and even Sōei's Demonic Thread Manipulation
…none of them could inflict even the slightest damage on Milim.
Among the ogre warriors, the only one who had managed to achieve anything at all was Shion, who had only just awakened.
At the start of the clash, she had swung her massive greatsword Gōriki-maru, forcing Milim to step back half a pace.
Looking at the blade that Milim had caught with one hand, Shion herself was shocked.
After awakening from her coma, she had already realized something incredible—
Her magicule reserves had reached unprecedented levels.
Compared to Rimuru now, she was hardly inferior.
If she possessed a Demon Lord Seed, she might even have qualified to call herself a Demon Lord.
And yet—
Her full-powered strike had been caught barehanded.
The attack had only forced Milim to step back half a step.
Were the Ten Demon Lords really this monstrously powerful?
But Shion wasn't the only one surprised.
Milim herself looked slightly intrigued as she held the blade.
"Looks like Clayman was completely talking nonsense," she said with a curious grin.
"He said the only strong monster here was the one that killed the Orc Disaster. But from what I can see, you're not much weaker than that slime over there."
Her eyes sparkled with interest as she studied Shion.
"And honestly, I'm curious."
"You're clearly stronger than the others here."
"So why would someone like you choose to serve someone whose strength is about the same as yours?"
She tilted her head.
"So tell me… who actually killed the Orc Disaster?"
"You?"
"Or that slime?"
Shion didn't answer.
Instead, she launched into a relentless flurry of attacks.
But Milim treated the entire exchange like a game.
Even while Shion fought at full power, Milim effortlessly overwhelmed her.
And when Rimuru unleashed a fusion attack combining Black Flame and Black Lightning—
Milim simply destroyed it with a single punch.
