Chapter 70: Genetic Mystery, Legion Face-Slapping

The "Demon: Gene Chain" is the "Extraordinary Factor" of the Blood Demon Art extraordinary system.

Yoriichi Tsugikuni’s "Demon Slayer Mark" and "Transparent World," and Abe no Seimei’s "Shikigami" are knowledge and technique types, not bloodline types.

Meng Yi, through the "Bai Xue System" he possessed, replicated seven or eight out of ten of the above knowledge and techniques.

He intended to parse, learn, master, digest, and absorb Muzan Kibutsuji’s "Demon: Gene Chain." Simply implanting and loading demon blood was too low-end.

……

With two or three slashes, he cut off the Scum Demon King’s cumbersome, queen-ant-like body.

Using nano-scale threads, he stitched together the original human-form Muzan Kibutsuji.

"B-grade: Psionic Energy" and "Microscopic Domain Interference" were activated simultaneously, covering every molecular structure of the Scum Demon King.

"A Demon King is a Demon King; this guy’s 'Gene Chain' is much more interesting than the SSR-grade lab rats!"

From the microscopic perspective, Muzan Kibutsuji’s gene chain presented the form of a "Triple-Helix Möbius Strip."

The helix symbolizing the "human part" and the helix symbolizing the "demon part" were relatively bright.

The "third" one attached between the "human" and "demon" parts was underdeveloped and could not achieve a perfect connection effect.

The pollution characteristic of the "Demon: Gene Chain" came from Muzan Kibutsuji; the pollution ability of the other Upper Moon demons (SSR) all came from the excessive demon blood bestowed by Muzan Kibutsuji.

The reason the Scum Demon King didn't awaken a spatial Blood Demon Art was that the total amount of his "Demon: Gene Chain" was occupied by "Source-level: Pollution."

"Missing…… the perfect creature, the Blue Spider Lily?"

Meng Yi took a sample of the Blue Spider Lily plant and observed the gene chains contained within it.

"It seems it can be embedded with the third gene chain to make up for the flaws."

He didn't rush to experiment on Muzan Kibutsuji.

Meng Yi cut off a few pieces of the Scum Demon King’s muscle tissue and placed them in a special culture dish to accelerate catalysis.

He then used "Molecular-level: Microscopic Domain Interference" to extract the gene chain of the Blue Spider Lily.

He embedded the Blue Spider Lily gene chain into the "Triple-Helix Möbius Strip" gene chain.

As soon as the two complementary things touched, a wonderful reaction occurred in the microscopic domain.

Muzan Kibutsuji’s "Human-Demon: Gene Chain" absorbed the Blue Spider Lily gene chain, rapidly proliferating and strengthening, becoming the same length as the "Human: Gene Chain" and "Demon: Gene Chain."

The overbearing "Human-Demon: Gene Chain" simultaneously entangled the "Human: Gene Chain" and "Demon: Gene Chain," carrying out cruel devouring and slaughter.

Meng Yi didn't stop it, observing the changes with great interest and guessing various possibilities.

A few hours later.

The "Human-Demon: Gene Chain" that had devoured the "Human: Gene Chain" and "Demon: Gene Chain" collapsed and disintegrated.

The demon and demon canceled each other out, leaving only the pure "Human: Gene Chain."

"The Blue Spider Lily is a good medicine to cure the 'Demon: Gene Chain' disease; it cannot turn Muzan Kibutsuji into the 'perfect creature' in my imagination, it will only result in a negative-negative-positive."

Meng Yi did several sets of repeated experiments, and the results were exactly the same, verifying his speculation.

"Then the question arises: why can Tamayo and Yushiro get rid of Muzan Kibutsuji’s control?"

"Why can Nezuko Kamado and Tanjiro Kamado become 'Complete Demons'?"

Protagonist halo?

Nonsense; to put it bluntly, it’s still the "Miracle: World Origin Crystal" at work!

After possessing "Molecular-level: Microscopic Domain Interference," Meng Yi wanted to rely on his own "Bai Xue System" to thoroughly research the mystery of the "Demon: Extraordinary Factor" and parse and master spatial abilities.

Of course, one could also say Meng Yi was poor; he didn't have a single cent in his pocket now.

……

Quickly checking the pharmacology of Tamayo and Shinobu Kocho organized by Red Queen, he found that "Woody Plant: Wisteria Tree" left heavy records.

"A bit interesting."

Meng Yi set off for the sample warehouse and took the sap and petals of the Wisteria tree.

He also went to the Infinite Castle: Demon Legion, randomly selected a few lucky cannon fodder, and sent them to the laboratory for a control group experiment.

Demons are destined to die; either lighter than a feather or heavier than Mount Tai.

Being able to sacrifice their lives for Meng Yi’s technological progress, these lucky demons who were about to win "Best Employee" should be happy.

……

A few days later.

After multiple experiments, it was found that the sap and petals of Wisteria had a significant restraining effect on demons with diseased gene structures.

Excessive ingestion or injection of "Wisteria: Gene Chain" would inevitably lead to the demon’s "food poisoning" and death.

Therefore, demons would hate the smell of Wisteria, and Wisteria had become a sharp weapon for the Demon Slayer Corps to fight demons.

Meng Yi constantly diluted the concentration of Wisteria sap, extracted a small amount of gene chain, and injected it into the bodies of cannon fodder demons whose gene chains were disordered and chaotic and lacked aesthetic appeal.

The "Wisteria: Gene Chain" rapidly eroded the "Demon: Gene Chain."

External manifestation: causing the demon’s cells to age rapidly in a short time; if the demon could not replenish the violent consumption, it would be deprived of life force and perish.

The heroic sacrifice of one cannon fodder demon after another allowed Meng Yi to master the appropriate ratio.

The demons undergoing surgical experiments were quite lucky.

The experimental subjects didn't die directly but entered a constant: weak state and got rid of Muzan Kibutsuji’s Demon King control.

"All things grow and restrain each other; the field of genetics is truly wonderful."

"What kind of luck does that Tamayo have! A blind cat bumping into a dead mouse, accidentally mastering the concentration ratio."

Meng Yi was filled with emotion, sighing at the power of "Molecular-level: Microscopic Domain Interference" and also at Tamayo’s dog-shit luck.

Looking through Tamayo’s data records.

She gained freedom because of the "Wisteria: Gene Chain" and wanted to manufacture a "Perfect Human Transformation Potion" based on "Wisteria" to kill Muzan Kibutsuji.

The idea was good, but the direction was wrong.

The "Wisteria: Gene Chain" could only kill or weaken diseased demons, causing their cells to age rapidly and their genes to collapse and die, but it could not replace the efficacy of the "Blue Spider Lily: Gene Chain."

"I lack the gene samples of Nezuko Kamado and Tanjiro Kamado……"

Meng Yi found that his experimental progress was stuck.

How could this be?

Whoever dared to delay his experiment would receive an invitation to the "Nine Clans Elimination" game!

"Red Queen, mobilize the Infinite Castle: Demon Legion."

"Go to the Swordsmith Village and capture Nezuko Kamado and Tanjiro Kamado alive. Be careful not to crush the Demon Slayer Corps."

"Also, by the way, test Shiki Ryougi’s mettle again. I am very dissatisfied with the performance of the last Upper Moon cannon fodder."

"Swordsmith Village…… Swordsmith Village…… also collect some samples of Scarlet Ore and Scarlet Sand."

Little Red Queen’s crisp and pleasant voice echoed: "Yes, Director."

……

With an order, the Infinite Castle, this terrifying war machine, fired on all cylinders.

Six SSR (Wormhole technology type) demons awakened, and six spatial wormholes leading to the Swordsmith Village were built.

Meng Yi paused the experiment, preparing to temporarily modify some cannon fodder.

After the strength iteration, the speed of cannon fodder modification surgery increased significantly. Cooperating with the advanced equipment in the experimental area, Meng Yi only spent seven hours to produce five or six hundred E-plus grade cannon fodder and fifty-seven D-minus grade cannon fodder.

With a test scale expanded by more than fifty times, paired with more than twenty thousand E-minus grade cannon fodder, presumably Miss Shiki Ryougi, whom he hadn't seen for a long time, would be satisfied with this sudden "surprise," right?

"Infinite Castle: Heaven-Net" simulated the Zerg unified thinking network, manipulated the twenty-thousand-strong demon legion, crossed the six stable spatial wormholes, and slapped the Swordsmith Village where the Demon Slayer Corps lived in seclusion.

……

In the quiet deep mountains and old forests, there was a peaceful and serene village.

The abruptly visiting demon legion broke the tranquility here.

The moon was bright and the stars were sparse, and black clouds filled the sky.

Under the cover of night, the demon legion, wearing pale bone exoskeleton armor, said nothing, the murderous aura dissipating, deterring the birds and beasts in the mountain forest to curl up into a ball and tremble.

The swordsmen responsible for guarding the Swordsmith Village rubbed their eyes in disbelief.

The arrival of the twenty-thousand-strong demon legion scared several black-clothed swordsmen into collapsing to the ground, losing their mental defense, and losing control of their bowels. It took a long, long time before they miserably rang the alarm bell, and the shrill exclamation woke up the sleeping Swordsmith Village.

A few hundred against tens of thousands—is the advantage with me?

*Hammer, yo.*

Fusang had never had legion-scale warfare of hundreds of thousands since ancient times; the so-called Warring States period was purely a village-town brawl.

After a flurry of chaos, hundreds of Demon Slayer swordsmen who had left their sleep hurriedly climbed the three-meter-high wooden city wall.

The swordsmen with weaker minds didn't even notice their Nichirin blades falling to the ground; they had already been scared silly by the number of the demon legion.

When there are a hundred people, they are of all kinds;

When there are ten thousand people, they are boundless;

When there are a hundred thousand people, they cover the earth and sky.

Wearing full exoskeleton armor and holding standard pale bone swords, every demon was a super Iron Pagoda.

Can a three-meter-high, one-meter-thick wooden city wall withstand a charge of the demon legion?

With all paths of survival stripped away, even someone as strong as Shiki Ryougi couldn't help but fall into despair.

She had already overestimated the players on the opposing side as much as possible.

Who would have thought that Meng Yi, this guy, would abandon martial virtue and, for the sake of two experimental subjects, transmit a twenty-thousand-strong army? Slapping them in the face with a big move.

*'What to do?! What to do?! What should I do?!'*

On the wall, Shiki Ryougi, wearing a plain white kimono and holding an extraordinary short blade, gritted her teeth, her mind running at high speed.

Even if she were exhausted to death, she couldn't kill the tens of thousands of the demon legion.

Activating the "Death Curse Body" might allow her to escape, but failure of the main quest was an inevitable result.

*'Should I abandon the Demon Slayer Corps?'*

*'Damn it!'*

*'What did that vampire who is good at large-scale destruction do? Could it be that she has already been killed by the enemy?'*

No matter how much she racked her brains, she couldn't understand that Flandre Scarlet was still in the Kyushu region, being played around like a silly dog.

Just as Shiki Ryougi was about to activate the "Death Curse Body" to run away, the twenty thousand demons spoke in unison.

"Hand over Tanjiro Kamado and Nezuko Kamado, and this battle can stop."

The neat and uniform voice shook the mountains and fields. Tanjiro Kamado, who was trembling on the wall, pointed at his cheek in astonishment.

The illiterate boy bypassed the Demon Slayer Corps small fry who were paralyzed in a pile and gathered his courage.

"I will go with you. Can you let my sister and the Demon Slayer Corps go? They are innocent!"

The dull, mechanical repetitive sound paused.

Psionic lifeform: Red Queen took over the demon network, each demon contributed a little "cell-level: biological psionic computer," and outlined the silhouette of Little Red Queen under the night sky.

With wings on her back, black hair reaching her waist, and red jade eyes shining.

Elegant, beautiful, yet filled with an absolute indifference to life; the non-human aura was even more intense than that of the demons!

"This is not a transaction……"

"Forget it, it’s impossible to communicate with a stubborn person. Better to suppress them."

Nano-scale cell material condensed into a blood-colored sickle. Red Queen waved the sickle, pointing at the Swordsmith Village with weak defenses, and said indifferently: "Kill half."

The demon legion ran and jumped at speeds exceeding human limits.

Pale bone blades flashing with cold light were drawn, shattering the low city wall of the Swordsmith Village, and the Demon Slayer swordsmen fell into the demon tide and were submerged.

The few Demon Slayer swordsmen who gathered the courage to resist appeared so futile and ridiculous in the large-scale legion battle.

……

E-plus grade cannon fodder and D-minus grade cannon fodder surrounded Shiki Ryougi, who was preparing to run away, forcing her to activate the "Death Curse Body" to fight.

Strange, ominous black patterns climbed her body, and her eyes, flashing with blue-purple rainbow light, saw the death lines of the enemies one by one.

"Is that all you have?"

Black-red wings flapped. Red Queen, in mid-air, teased: "Do you have any other skills? If you don't use them now, you won't have a chance."

The C-grade extraordinary short blade was activated, extending into a magic blade wreathed in magical brilliance and blood patterns that kept jumping.

*'Sun Breathing: First Form: Dance!'*

Extraordinary physique + technique slash; the circular magic arc expanded, precisely cutting the death lines of the cannon fodder demons one by one.

The area of several dozen square meters around her was cleared, and Shiki Ryougi looked up and glared at Red Queen.

"Are you the player from the demon camp?"

Little Red Queen tilted her head, her smile bright. "If not me, then who?"

Shiki Ryougi was trembling with anger. Tens of thousands of compatriots! This number was too terrifying!

If Shiki Ryougi knew the truth—that Fusang had only 25 million+ "White Cards" left, and a full four or five million had been polluted into demons—she estimated her anger value would have exploded directly.

"Why kill the innocent? What exactly do you treat life as!"

"Huh?"

Red Queen pouted in disappointment. "Just this? Do you remember how many slices of bread you’ve eaten? I thought you could say something shocking."

"We are enemies, eh? This is a faction confrontation mode. How can you stand on the moral high ground and righteously accuse me of my behavior?"

Anger, extreme anger!

With nothing more to say, Shiki Ryougi gave up communicating with Red Queen.

The only way now was to kill this player from the opposing camp and end the demon scourge.

She would use the blade in her palm to act on behalf of heaven and sever the tangled thousand-year grudge!

*'"Demon Slayer Mark," burn!'*

*'"Transparent World," open!'*

Patterns resembling burning flames appeared on Shiki Ryougi’s forehead, cheeks, and neck…… raising her basic physical fitness by a small margin and further increasing the upper limit of activating the "Death Curse Body."

"An extreme evil like you who ignores life has no value in existing!"

"I have already seen your 'death.' Within ten seconds, I will slaughter you!"

Shiki Ryougi, like a pure white reverse-flying star, carried circles of Mach rings and attacked the mortal enemy in mid-air with unstoppable force.
