Looking at the Lower Rank Five, who was wailing like a lump of mud at the bottom of the pit.
Sanemi Shinazugawa spat out a mouthful of spittle in disdain.
"Tch, what a useless piece of trash! He couldn't even withstand two of my moves. With a performance like that, how could he possibly serve the purpose of testing that kid?"
Sanemi swung his Nichirin Blade, just as he was hesitating whether to jump down and give the little spider a couple more kicks to "stretch its limbs."
"Oh dear, Mr. Shinazugawa really went all out!"
A faint, fragrant scent appeared at the bottom of the pit, right behind Lei's head.
"If this keeps going, it'll break down prematurely!"
It's Shinobu Kocho!
She had climbed down from the tree branch sometime earlier.
At this moment, she still wore that sweet, angelic smile on her face.
But!
In her right hand, she was holding a syringe that sent shivers down one's spine and made one's legs tremble!
The transparent glass syringe was filled with nearly three hundred milliliters of scarlet liquid!
The liquid was boiling slightly inside the syringe, producing tiny bubbles.
"What... what do you want to do?! Don't come any closer!"
Lei, lying in the mud, was beaten so badly he couldn't get up, but his ghostly instincts kicked in the moment the syringe appeared!
He sensed a deadly threat from that crimson liquid that was far more terrifying than the white-haired man's fist from before!
It was an aura of destruction originating from the depths of our genes!
"Shh~ Don't move, little spider. Be a good boy and get your shot, then you'll become super strong~"
Shinobu Kocho a smile, reached out her left hand and pressed down on Rena's struggling head.
That smile, in Lei's eyes, was more terrifying than the most vicious devil in hell!
Without any hesitation.
Shinobu raised the syringe high, a dangerous smile like that of a devil, and mercilessly plunged the steel needle into Lei's carotid artery at the back of his neck!
"Pfft!"
Blood spurted out!
"Ahhh--!"
With Shinobu forced all 300 milliliters of the scarlet liquid into Rui's body within two seconds!
"Done!"
Shinobu pulled out the needle, flicked the blood off the syringe with disgust, and lightly leaped out of the pit, arriving beside Sanemi.
"Hey, you cunning woman, what kind of weird stuff did you give him?"
Sanemi looked at the pit bottom, which was beginning to convulse violently as if electrocuted, and asked with a furrowed brow.
"This is the ' Potential-Stimulating Drug 'God-Making Plan I've been developing for half a month, the result of my hard work!"
Shinobu clapped her hands, took off her medical gloves, and explained with a smile,
"Its function is to forcibly break the genetic shackles of demons, allowing their strength to break through its limits in a short period of time, resulting in a terrifying qualitative change~"
"Qualitative change?"
Sanemi snorted coldly.
"What good is this mere potion? Can it turn this useless Lower Rank into Upper Rank?"
"Of course!"
Shinobu covered her mouth and chuckled softly, her purple eyes gleaming with a fervent scientific spirit.
"However... the reason this potion has such a powerful effect is because its main ingredient is Hyperactive Blood Cells provided by Mr. Giyu Tomioka ~"
"What?!"
Sanemi paused for a moment, "The blood of the person with facial paralysis?"
"That's right~"
There was even a hint of surprise in Shinobu's tone.
"Mr. Giyu's physique is simply abnormally abnormal. His cell division and phagocytosis rates are a hundred times faster than those of ordinary people! This is an exceptional recovery ability for humans."
"However, for the genes of demons, Mr. Giyu's cells are simply the most deadly and potent poison in the world!"
Shinobu pointed to the pit bottom and said in an excited tone, as if she were looking at a lab rat:
"When these cells, brimming with ultimate vitality, are injected into the demon's body, in order to resist this foreign 'poison,' the demon's body will unleash all its potential, forcibly elevating its own strength to suppress it!"
"This process will briefly grant him terrifying power comparable to that of Upper Rank."
"But the price..."
Shinobu's smile turned incredibly cunning.
"Mr. Giyu's cells are just too domineering! Even though they were diluted many times over, even Lower Rank would be unable to withstand this high-intensity cell fusion battle after the injection, and would completely collapse genetically within 24 hours, turning into a puddle of pus~"
"So, he's currently just a... one-time-use 'inferior Upper Rank's with only a one-day lifespan~"
Listening to Shinobu's explanation...
(P. S.: To clarify, it's not that Giyu's blood strengthens the demons; blood is just one part of the potion!)
Even the hot-tempered Sanemi couldn't help but gasp.
He glanced at the agonizing exhaustion at the bottom of the pit, then at the smiling Shinobu Kocho beside him, and couldn't help but curse inwardly:
"Giyu Tomioka, that expressionless guy, is a pervert, and that woman is insane too! This scumbag couple is a perfect match!"
Meanwhile, the changes at the bottom of the pit had reached a fever pitch!
"Roar--!"
After the drug was administered, Giyu's super-active cells began to rampage wildly within Lei's body!
His pale skin instantly turned crimson!
Countless bluish-black blood vessels, resembling earthworms, bulged and throbbed wildly on his body, as if they were about to burst at any moment!
His shoulder, which had been smashed by Sanemi, and his broken ribs were forcibly healing and recombining at a speed visible to the naked eye, amidst a series of grinding sounds!
"Boom--!"
A terrifying, suffocating Demon Aura finally surged upwards from Lei's body!
The shockwave was so strong that it blew the soil off the bottom of the pit!
The ancient trees within a radius of dozens of meters were snapped in half by the impact of this Demon Aura, making crisp cracking sounds!
"This aura..."
Standing at the edge of the pit, Sanemi felt the gust of wind rushing towards him.
His bloodshot eyes were instantly filled with an excited fighting spirit!
"They actually crossed that threshold and reached the Upper Rank level?!"
Sanemi gripped the blue Nichirin Blade tightly in his hand, the blade emitting an excited clang.
"That's awesome! This is fucking fun!"
Sanemi grinned, revealing his gleaming white teeth, like a hungry wolf eyeing its prey!
"I'll chop him into pieces right now!"
With that, Sanemi was about to draw his sword and jump into the deep pit.
However--
"Snap."
A slender little hand steadily held his haori.
"No, Mr. Sanemi."
Shinobu Kocho's smile vanished, her gaze becoming incredibly serious and focused.
"Please restrain your fighting spirit, and don't forget the plans of our Master and Mr. Giyu."
Upon hearing these words...
Sanemi tightened his grip on the hilt of the sword.
A full three seconds passed.
"Cut..."
Sanemi spat in extreme displeasure.
He forcibly suppressed the surging fighting spirit within him and abruptly sheathed his Nichirin Blade.
"What a disappointment. I hope that brat doesn't die a horrible death."
Sanemi turned around and strode towards the outer perimeter of the core area.
"Let's go, our mission is complete."
Shinobu took one last look at the bottom of the pit, then turned around gracefully, like a purple butterfly, and followed Sanemi's steps.
The two figures disappeared into the endless darkness without a trace of regret.
And in the huge, deep pit behind them.
"Boom--!"
Rui, the Lower Rank Five, whose power had surged to an unbelievable level and who had undergone a complete mutation, slowly floated from the bottom of the pit into the air.
His eyes, now completely blood red, had lost all reason, leaving only the purest pain and a frenzied desire to kill.
"Kill... kill you all... kill everything..."
Super Spider Demon Lei raised his head and let out a soul-rending howl towards the pitch-black night.
