Chapter 71

The human-shaped body dissipated, and Red Queen, who could not be observed by the naked eye, escaped in the form of a psionic lifeform.

"Bastard!!"

Shiki Ryougi was broken by anger. With full state and full buffs, the feeling of missing the target was extremely tormenting.

"Friend, you've only grown this much in more than seven months; you've disappointed me too much."

"Too weak, you'd better play with the twenty thousand cannon fodder, bye-bye~"

Red Queen, through the "Infinite City: Heaven-Covering Net," used the mouths of the twenty thousand cannon fodder to mock Shiki Ryougi with sarcastic remarks.

Shiki Ryougi's forehead veins bulged, and bloodshot eyes climbed onto her blue-purple magic eyes.

The enemy clearly looked like they had good strength, but chose a legion war of attrition; it was truly despicable!

"You just wait! I've remembered your face!"

"It's best not to meet in the same dungeon in the future, otherwise I will go to the ends of the earth to kill you!"

Little Red Queen, who was manipulating the legion, retorted with a poisonous tongue.

"Hey, how do I say this to you? Because of some compelling reasons, I only killed a tiny bit of the 'compatriots' in your cognition……, but you are stubbornly unwilling to let go."

"Friend, you have no compatriots, but you have me! I can completely be a friend on your life's path, just like how you get along with the Demon Slayer Corps."

"I*&! %#!"

Infuriating! Too infuriating!

If it can be endured, what cannot be endured? Today, I must explode with her!

Unable to find Red Queen, she took her anger out on the demon legion!

First break! Crouching Dragon comes out of the mountain!

Not long after, all the high-level cannon fodder temporarily modified by Meng Yi died under her butcher knife.

"Oh my, that's terrible, friend. They are your compatriots; how can you be so cruel?"

Red Queen's incessant verbal provocations came from the mouths of every demon, and her true location could not be locked at all.

Shiki Ryougi turned a deaf ear, hatred had eroded her soul, and she continued to slaughter the demons wearing exoskeleton armor.

Second break! Famous in one battle!

The beautiful white figure shuttled through the demon tide, and wherever she passed, it was like a grim reaper harvesting life, and the demons fell one after another.

"Think about it, when demons become the mainstream and the Demon Slayer Corps becomes the alien, who is right? Who is wrong?"

Third break! The world is shocked!

C-rank physique + "Mystic Eyes of Death Perception" + C-rank extraordinary magic blade, every sword light could harvest dozens of demons.

Shiki Ryougi's physical strength was more than half exhausted, and she had killed a quarter of the demons.

The "Death Curse Body" + "Demon Slayer Mark," which heavily squeezed her body, brought a heavy burden, and she almost couldn't maintain the buff stacking state.

Other battle circles had already ended, but only Shiki Ryougi was still putting up a desperate resistance.

Demon Slayer Corps leader Kagaya Kiriya, a young child, squatted on the ground like a quail, trembling.

Amane Ubuyashiki kept comforting her crying daughters.

Tanjiro Kamado, Nezuko Kamado, Shinobu Kocho, Kanao Tsuyuri……, exhausted, they were tied up by the demon legion, and their jaw joints were removed to prevent suicide.

"Hoo—hoo—"

Beads of sweat trickled down Shiki Ryougi's forehead, and her plain white kimono had long been soaked in blood and sweat. She glanced at the Demon Slayer Corps, which had lost 50% of its personnel but whose key members were all alive, with the corner of her eye.

Her confused mind couldn't figure out what Red Queen's intention was.

"Why not end the dungeon main mission?"

"Guess~" Red Queen was infuriating, continuing to output.

Shiki Ryougi gritted her teeth and stopped looking at the Demon Slayer Corps.

The enemy invaded in large numbers, and she had already tried her best to resist. The kindness of learning the Sun Breathing technique, Demon Slayer Mark, and Transparent World had been repaid.

The top priority is to prioritize her own safety.

"Extreme: Death Curse Body!"

C-rank physique → C+ rank physique!

Dense tadpole-like curse patterns condensed into a black spider lily pattern, looking extremely evil.

Shiki Ryougi in the limit state might be able to kill the remaining fifteen thousand demons, but she would inevitably die of exhaustion.

"Friend, are you going to run away? Are you not going to take revenge on me?"

"Today's affairs are finished today. Tomorrow after tomorrow, how many tomorrows are there~"

"Get lost!!"

Since the start of the battle, Miss Shiki Ryougi, who had been broken, retorted to Red Queen for the first time.

With a fierce stomp, the earth for several kilometers around shook violently.

Dust rose, cracks spread, and Shiki Ryougi ran away.

Watching the figure moving further and further away disappear at the end of her line of sight, Red Queen slowly condensed her silhouette.

"Friend, the whole Fusang is my eyes, you can't run away~"

To prevent Shiki Ryougi's "cerebral thrombosis" from recovering and making a comeback to kill the Demon Slayer Corps, thereby ending the Demon Slayer dungeon, Red Queen ordered six SSR wormhole technology demons, including Nakime, to open channels and teleport the remaining Demon Slayer Corps members to the Infinite City.

As for the small fry in the Swordsmith Village, clean them up.

After finishing the main work, Red Queen manipulated the fifteen thousand demon legion to search for valuable items in the Swordsmith Village.

Not long after, the Yoriichi Type Zero puppet, Scarlet Ore and Scarlet Sand samples, and Nichirin sword forging classics were all packed up.

The battle between the demon legion and the Swordsmith Village ended with a great victory for the demon legion.

Everyone in the Demon Slayer Corps received a small room in the Infinite City.

Move in with bags, three meals free, and prevent backstabbing from Shiki Ryougi and Flandre.

……

Tokyo Prefecture: East City District: Underground Infinite City.

"Lord Director, Shiki Ryougi 'successfully' escaped."

Little Red Queen, who was one step behind Meng Yi, waved her hand and summoned the 24h no-dead-angle surveillance screen of Shiki Ryougi.

The Japanese people, who had lost nearly half their numbers and were skinny, working 18 hours a day, were shocking.

Shiki Ryougi wanted to awaken the will of her "compatriots."

But the Japanese people, who had long been scared out of their wits, heart-dead, and numb, how could they seek death?

"Do you need to lock her in the experimental area and make her into a specimen?"

"According to calculations, it is expected that in 278 days, Shiki Ryougi has a 95.72% possibility of finding the location of the Infinite City headquarters by following the clues."

Meng Yi's palm fell on Red Queen's head, rubbing the black hair that was as smooth as silk on Little Red Queen.

"No need."

"What Shiki Ryougi resents is Red Queen; what does it have to do with me, Meng Yi?"

"This dungeon is an enemy, and no one can say for sure what will happen in the future."

"Just like I'm thinking about the Three-Body worldview of Luo Ji's hometown and the Honkai worldview of Firefly's hometown, the Type-Moon worldview of Shiki Ryougi's hometown is also very valuable."

"Hehehe~"

Red Queen narrowed her eyes and smiled foolishly. She stood on tiptoe like a little pet, rubbing her head against Meng Yi's wide palm.

"Yes! Then start the "Misguidance Plan" and delay the time as much as possible."

"Lure Shiki Ryougi to the Hokkaido region and separate her from Flandre Scarlet in the southern Kyushu region."

Meng Yi nodded slightly, "Well, I'm going to the experimental area."

"Yes."

Little Red Queen patted her flat chest and promised confidently: "There won't be any trouble~"

Meng Yi's eyelids twitched. Looking at Little Red Queen's appearance like an old general on a stage, he always felt that she would overturn at any time.

"Note, don't lead the war to the Tokyo Prefecture area."

"Yes!"

……

Infinite City: -2 floor experimental area.

Research needs to go from easy to difficult. Meng Yi collected forging classics while analyzing the molecular arrangement structure of the basic materials of Nichirin swords.

Scarlet Ore, main components: hematite, crystalline silicon……

Due to its special molecular arrangement order, this thing has the firmness of iron and can also be regarded as a natural solar panel.

By storing solar thermal radiation energy during the day, it causes restraint damage to demons when fighting demons in the wild.

"Barely okay."

Meng Yi was uninterested and casually stored the molecular structure of Scarlet Ore into the "Big Data Library: Memory Palace" to enrich his foundation.

The puppet Yoriichi Type Zero forged in the Swordsmith Village imitating Yoriichi Tsugikuni.

A secular technique-type imitation, it only imitated the 'form' of Yoriichi Tsugikuni, but lost the 'spirit' of Yoriichi Tsugikuni. It's small fry goods, very average.

It's a harvest anyway. Meng Yi extracted and saved the idea of the biomimetic puppet.

……

Meng Yi paced to the test bench, where Nezuko Kamado in a coma was placed.

"B-rank Psionic Power" and "Microscopic Domain Interference" were activated, and the Bai Xue instruments were running at full power, and every molecule structure of Nezuko Kamado was clearly visible.

"Huh, interesting!" Meng Yi's eyes lit up slightly.

From the microscopic perspective, Nezuko Kamado's gene chain presents a "triple helix: Mobius strip" form that looks like Muzan Kibutsuji's, but there are differences in the details.

Nezuko Kamado's third "Human-Demon Gene Chain" is more perfect than the scum demon king's, but not as long and perfect as the "Human Gene Chain" and "Demon Gene Chain."

"The reason is 'not strong enough'!"

"It is precisely because it is 'not strong enough' that the "Human-Demon Gene Chain" can only play the role of suppression and centering balance, and cannot destroy the basic balance of the "triple helix: Mobius strip"!"

Meng Yi raised his finger slightly, and the thousands of nano-scale silk threads extending out went into Nezuko Kamado's mind, reading her childhood memories.

Living in an environment where the Blue Spider Lily blooms seasonally for a long time, Nezuko Kamado's "Human Gene Chain" was subtly influenced by the "Blue Spider Lily: Gene Chain," and she innately possessed resistance to the "Demon Gene Chain."

Note, it was Nezuko Kamado who first contacted the "Blue Spider Lily: Gene Chain" and then contacted the "Demon Gene Chain." The order cannot be messed up!

Three years ago, Muzan Kibutsuji polluted Nezuko Kamado.

This experimental subject fell into a long sleep state due to 'gene disorder' and adjusted herself by burning "trace world origin."

She not only got rid of the scum demon king's demon blood control but also evolved slowly towards the direction of a "perfect demon" to a certain extent.

It's a pity that the "miracle favor" contained in Nezuko Kamado is not enough, and there is still the last step that needs to be made up.

"Wisteria?"

Meng Yi muttered to himself. If his memory was not wrong, it was Tamayo who helped Nezuko Kamado complete the final transformation, leaping to become a "perfect demon" who is not afraid of sunlight.

"I understand the production process of "Complete Demon"."

"① First be polluted by trace "Blue Spider Lily: Gene Chain"; ② then be polluted by "Demon Gene Chain"; ③ sleep and transform, "Blue Spider Lily: Gene Chain" vs "Demon Gene Chain"; ④ "Wisteria: Gene Chain" completion."

"The good medicine to cure demon disease: Blue Spider Lily, the fierce poison to kill demon disease: Wisteria, both are indispensable!"

"So, "Complete Demon" only appeared in two cases!"

Meng Yi cleared his thinking and decisively went to the warehouse to take "Lab Rat: Tanjiro Kamado."

Tanjiro Kamado was not polluted by the "Demon Gene Chain," but he still had a "Blue Spider Lily: Gene Chain" in his body that looked like a "Human-Demon Gene Chain" but was essentially completely different, only it was not as long and perfect as Nezuko Kamado's.

"Next, it's very simple. Repeat the experiment, adjust the ratio, and keep trying and making mistakes."

The Kamado siblings need to burn "trace world origin" to urge their own perfect evolution.

Meng Yi, who possesses "Molecular-level Precision: Microscopic Domain Interference," has to a certain extent gotten rid of his dependence on "World Origin Crystals." At the very least, F-rank, E-rank, and D-rank have no meaning.

If Meng Yi returned to the selection dungeon: Biohazard world now, he wouldn't need to waste "World Origin Crystals" at all and could hand-craft "Longevity Gene: Type 3: Virus Progenitor" himself.

……

The Infinite City's "small rooms" have ready-made Demon Slayer Corps samples, no need to go outside to catch malnourished, dying "White Cards."

Notifying Red Queen to send Shinobu Kocho and Kanao Tsuyuri to the experimental area, Meng Yi explored the production plan of "Complete Demon" on the two lab rats.

As soon as he checked, Meng Yi shook his head in disgust.

"The order is wrong; these two lab rats are soaked in Wisteria."

Work didn't go smoothly.

The Demon Slayer Corps lab rats that were transported later all lost the possibility of being promoted to "Complete Demon" because they had been in contact with Wisteria for a long time.

Of course, Meng Yi could also use "Microscopic Domain Interference" to wash away the "Wisteria: Gene Chain" contained in the Demon Slayer Corps lab rats.

It's too time-consuming. There are plenty of lab rats, why bother?

"Red Queen, go outside and catch a few "White Cards," I have a use for them."

"Yes."

……

Ten minutes later, hundreds of "White Cards" were sent to the experimental area on the -2 floor of the Infinite City.

There is nothing to say, a "vegetative impact" at the meeting, crushing the thinking of the lab rats.

Meng Yi began to produce the mysterious "Complete Demon" according to the process he inferred.

One "Bai Ka" after another was scrapped because the ratio was wrong.

26 days later, the first successful experimental subject was born, and the prompt sound of "Evolution Paradise" arrived as scheduled.

【Hint: Player "Bai Mo" perfected the "Demon: Bloodline: Extraordinary Factor" evolution route, changed the world pattern to a medium extent, and obtained C-rank evaluation: 1 + 10,000 Paradise Coins.】

Meng Yi didn't ask or care, continuing to bury his head in scientific research.

……

On the 307th day of descending into the Demon Slayer dungeon, he embedded the ability of spatial demons into the cumbersome "Complete Demon" production process and simplified it into a fool-proof injection-type medicine.

"Let's call it "Longevity Gene: Type 4: Complete Demon"."

【Name: Longevity Gene: Type 4: Complete Demon

Creator: Bai Mo (Meng Yi)

Evaluation: C-rank: Bloodline Gene-type Enhancement Medicine

Effects: ① Endless lifespan (can extend life by absorbing energy); ② D-rank body strength; ③ Body alienation; ④ Bloodline ancestor-level pollution spreadability; ⑤ Customizable spatial ability (space gate, space teleportation, space creation, choose one of three).】

"Hmm? It actually has C-rank? Same level as "Longevity Gene: Type 3: Virus Progenitor"?"

"Did the theoretical endless lifespan and spatial ability increase the upper limit of this medicine?"

The protagonist will not inject "Longevity Gene: Type 4: Complete Demon."

He wants to develop the basic framework of "Bai Xue Combat Body v2.0" based on "Longevity Gene: Type 4: Complete Demon" + "Shenhe Civilization Gene Engineering."

Children choose one of three from space gate, space teleportation, and space creation; adults of course want them all.

I asked in the reader group, and the godfathers said that 4000 words per chapter is more appropriate.

2000 words is too little, nothing to see.

8000 words is too much, easy to get tired.

Finally, the range of 3000~4000 was selected.

……

It's the beginning of the month, asking for monthly tickets~

Godfathers, I want 1000 monthly tickets this month. It's not bad to draw a pack of toilet paper from the author's welfare.

Can the godfathers who plan to raise the book give an automatic subscription? ^_^
