Chapter 2: Demon Slayer World. Dark Alloy Weapons. Xiao Bai Yue: My Lord is a Big Fool!

"T0, scan this world to see where we are." After changing clothes, Zero commanded his loli-sized robot to check which world they were in.

"Yes, my lord. Scanning initiated... Scanning complete."

"My lord, the world we are in is a Dimensional World—the Demon Slayer World. It is a world where evil demons run rampant. The place we are currently in is a small country called Nihon."

"Nihon? Why does that sound so familiar? Why can't I remember? A world where evil demons run rampant... T0, is this world very dangerous?"

"My lord, it is nothing for you, but since we are under Shou Dao Le Gao Jie, many things cannot be used in this world!"

"I see."

"I'm sorry, my lord. Due to Shou Dao Le Gao Jie, I can only obtain this information." T0 said dejectedly.

"It's fine, you've done very well!" He held T0 in his hand and stroked her head.

"By the way, T0, I'll give you a name."

"Okay, my lord! What name will my lord give me?" T0 knelt in the palm of Zero's hand, looking at him with big, sparkling eyes, and asked with great anticipation.

"Previously, Sister Luo Li said my old name was Bai Bai Yue, but I don't remember many things. So I'll call you Xiao Bai Yue."

"Yay! I have a name! I'm Xiao Bai Yue, hehehe! I'm so happy!" Xiao Bai Yue floated up happily and spun around Zero.

"Alright, Xiao Bai Yue, let's find a place to rest quickly, and also gather information about this Dimensional World called Demon Slayer to prepare for the future!"

"Okay~" Xiao Bai Yue replied, then sat on Zero's shoulder.

Zero and Xiao Bai Yue walked along a country path, their strange appearance causing everyone to feel surprised.

Especially Xiao Bai Yue; her small body sitting on Zero's shoulder made others' gazes full of confusion.

And so was Zero: wearing a white shirt with a black jacket, black tight pants with a leather skirt over them, a pair of black semi-metal high boots on his feet, white hair, blood-red eyes, and exquisite features. It made people look on in amazement.

"My lord, why are they all looking at us like that?"

"Because we are not from this world. It is normal for them not to understand us."

"Oh."

Just as they were speaking, a person dressed in samurai clothing appeared in front and blocked their way. He said: "Hand over all your money!"

"What is he saying?"

"My lord, he is speaking the language of Nihon. You can activate your language conversion function."

"I see. Activate language conversion function!"

In an instant, a single-sided analysis glasses similar to Bluetooth appeared on Zero's left ear, translating the language. The words spoken were transmitted to the other person's brain via radio waves by the analysis glasses, but to the samurai's eyes, it looked exactly like pure Nihon language.

Samurai: "Hand over all your money."

"Uh, Xiao Bai Yue, did I just run into a robbery?"

"Yes, my lord. However, this guy seems a bit not right in the head, hehe." Xiao Bai Yue sat on Zero's shoulder, letting her small legs dangle, and said with a smile.

"Fine, then let's do as he says."

He then pointed at the samurai in front and said: "You, hand over all your money, and I won't hold what you said against you!"

"Nani—Σ(? Д? |||)━, kid, now I am... pfft!" Before the samurai could finish speaking, Zero kicked him straight in the stomach, sending him flying.

"Little brat, I don't know how many years older I am than you. You dare call me kid? Are you tired of living?"

"My lord, your appearance right now does indeed look a bit like a child in school."

"Uh... that does seem to be the case!"

Saying this, he walked up to the samurai.

"Hand over all your money and I'll let you go. Otherwise... hmm!" Zero clenched his fists, making a "crack crack" sound.

"I... I... I'll hand it over. My lord... I... I was wrong. Please spare me!" After speaking, he endured the pain in his stomach, took out a bag of money from his chest, and handed it to Zero.

"You know your place. You can go!"

"Thank you, my lord! Thank you, my lord!" The samurai, ignoring the pain in his stomach, immediately ran away, fearing Zero might change his mind the next second.

"Over fifteen hundred yen, not bad. Xiao Bai Yue, can you find the nearest town from here? We should find a place to rest."

"Let me look... Found it. My lord, there is a small town about fifteen li from here."

"Alright, let's set off. We'll also learn about the information and related intelligence of this world. If possible, I'll also try to find a way to return."

"My lord, shouldn't you give yourself a name in this world too? Otherwise, what should you say if someone asks?"

"A name? Then I'll use my codename—Zero."

"My lord, the name you gave yourself is so casual."

"It's just a name for myself. Besides, we are just passersby in this world; we will leave one day."

Three days later.

Since Zero arrived in the town and checked into a small inn, he began collecting all information about the Demon Slayer World.

According to the reports collected by him and Xiao Bai Yue, this Demon Slayer World is a world where evil demons run rampant. Every night, evil demons appear, specifically hunting humans.

The creator of these demons is the ancestor of demons—Muzan Kibutsuji, a demon who has lived for a thousand years.

As for why he created so many demons, he also collected a little bit of relevant information: it was to find a plant called the Blue Blue Bianhua.

Through Xiao Bai Yue's analysis, he learned that this flower could allow Muzan Kibutsuji to become an ultimate creature unafraid of sunlight.

Muzan Kibutsuji also has direct subordinates known as the Twelve Kizuki, whose specific strength is unknown.

In three days, only this intelligence was collected, not much. Moreover, from this information, he learned of an organization that fights demons called the Demon Slayer Corps, but the specific situation is still being collected.

"Sigh, I didn't expect this world to be somewhat complex. Muzan Kibutsuji, truly interesting." Zero thought to himself.

"My lord, what are you thinking?" Seeing her master sitting by the window in a daze, Xiao Bai Yue couldn't help but ask.

Zero: "Nothing. Xiao Bai Yue, do you know how long I have lived?"

Xiao Bai Yue: "Xiao Bai Yue is not quite sure. Xiao Bai Yue only knows that since my lord created me, I have accompanied you for eleven centuries, and after that, you slept for two more centuries."

"But Sister Luo Li once told me that you lived alone for twelve centuries before creating me. Apart from when taking on missions, when you'd willingly fight alongside everyone, you were always alone."

"Master, from now on Xiao Bai Yue will always be by your side. Don't bear so much alone anymore, okay? Xiao Bai Yue is also your family—whatever it is, Xiao Bai Yue will share the burden with you."

Zero turned his head to look at Xiao Bai Yue. It was the first time he had heard her speak her own thoughts. He cupped her in his hands, gently stroked her cheek with a finger, and smiled. "You child—it's the first time I've seen you express your own thoughts. Still, thank you, Xiao Bai Yue."

"As long as Master is happy, I'll be happy too." Xiao Bai Yue wrapped her two little hands around Zero's finger as she answered.

"Oh right, Xiao Bai Yue—although we're being suppressed by this World's Boundary, there should still be some weapons I can use, right? What weapons are available to me right now?"

"Master, I've already checked this. The vast majority of dark-matter weapons can no longer be used, but the dark-alloy weapons you created in your spare time can still be used in this world. I've recorded them all in a list—I'll send it to you now so you can take a look."

Zero's analytical glasses received the list Xiao Bai Yue had sent and he took a look: Nano Space, two Healing Pods, Dark Alloy Cross Floating Cannons x8, Dark Alloy Gatling Gun, Dark Alloy Annihilation Sniper Rifle, Quantum Dual Pistols, Dark Alloy Paralysis Gun, Dark Alloy Type-4, Light-Energy Flyer, 20 Destroyer Micro-Drones, Dark Alloy Armor, Quantum Shield,

several hundred thousand energy crystals, as well as one giant dark-alloy combat mecha and a large batch of daily necessities and clothing.

Nano Space: a massive storage space of tens of thousands of cubic meters, built by Zero over the course of ten years.

Healing Pod: a small gas chamber capable of treating injuries. Place the wounded inside, add energy crystals, and as long as the patient still has a breath left, treatment can be carried out rapidly.

Dark Alloy Cross Floating Cannon (Dual Form): a cross-shaped cannon frame composed entirely of dark red and dark gray. It can attack from afar and defend at close range. Add energy crystals to activate an ultra-powerful defense mode and a long-range attack mode! The second form can switch to a machine-gun mode!

Dark Alloy Gatling Gun: a cannon with tremendous firepower. Add energy crystals to enable prolonged sweeping fire. One energy crystal provides three minutes of fire support.

Dark Alloy Annihilation Sniper Rifle: possesses tremendous penetrating power. Hitting a target produces a massive explosion, inflicting unimaginable damage on the target.

Dark Alloy Annihilation Sniper Rifle

Quantum Dual Pistols: fire quantum bullets by absorbing quantum from the surrounding air. If energy crystals are added, the bullets generate a small wave that shatters the body's functions.

Quantum Dual Pistols

Dark Alloy Paralysis Gun: add energy crystals to fire. Hitting an enemy generates an electric current that paralyzes the body's nerves.

Dark Alloy Paralysis Gun

Dark Alloy Type-4: equipped with four dark-alloy great swords, each sharp enough to split the hardest dark iron and stone. Adding energy crystals grants it sun-like scorching ability as well as freezing ability.

Light-Energy Flyer: possesses black-and-white dark-alloy metal wings. It charges using sunlight or by adding energy crystals, enabling sustained flight.

Destroyer Micro-Drone: only the size of a palm. After adding energy crystals, it can continuously fire high-explosive bullets with considerable destructive power.

Dark Alloy Armor: once equipped, it greatly enhances one's combat ability and possesses tremendous defensive power! If damaged, adding energy crystals enables automatic repair.

【Dark Alloy Armor】—not drawn very well, please forgive me

Quantum Shield: add energy crystals to generate a shield with a three-meter radius. The more energy crystals added, the stronger the defense.

Giant Dark Alloy Combat Mecha: a combat mecha standing ten meters tall. Black and red dark-patterns flow across its surface, and two giant swords are mounted on its back. It possesses tremendous destructive power and defensive power. Adding one hundred energy crystals enables thirty minutes of sustained combat.

【Giant Dark Alloy Combat Mecha】—drawn using a Gundam as the model. If you don't like it, please don't flame

"The combat mecha is good, but unfortunately it consumes too many energy crystals. If only I'd known, I wouldn't have built it back then. Still, I'll keep it—at the very least it might come in handy later.

These weapons are enough. At the very least they'll ensure we have sufficient power to protect ourselves before we leave this world. You've worked hard, Xiao Bai Yue."

"It wasn't hard. Oh, Master—a small portion of the functions on your left-hand dark-matter mechanical arm can also be used in this world."

"Mm."

"Um, Master, I…"

"What is it, Xiao Bai Yue?"

"I…" Xiao Bai Yue's face twisted shyly, her little cheeks flushed red, not knowing what to say.

"Um, it's just—I want to take a bath." Having said that, she covered her face with both hands.

"Huh?! Why would you suddenly want to take a bath?" Zero was curious. Although Xiao Bai Yue was a robot, she embodied the pinnacle of advanced technology. Apart from her exterior being one hundred percent lifelike, her internal structure was no different from a real person's.

"Xiao Bai Yue doesn't know why either. It's just that after arriving in this world, I felt like taking a bath. If I don't bathe, I'll feel very uncomfortable."

"Oh you, you—fine then. Wait here for me, I'll go prepare it for you." Zero was caught between laughter and tears, but he went along with Xiao Bai Yue's wishes and prepared it for her.

After a short while, Zero came up from downstairs carrying a small basin of hot water. He walked into the room, set it on the table, then closed the door. He then took a few pieces of white cloth from the Nano Space and arranged them around the small basin, making it look like a small bathroom.

"Here's a towel, and some clothes I made for you before. Make do with these for now—go ahead and wash in here."

"Thank you, Master! Mwah~ Master, you're the best, hee hee!" She kissed Zero, then flew toward the small bathroom, took off her clothes inside, and prepared to bathe.

Zero touched his own cheek where Xiao Bai Yue had kissed him, smiled slightly, and thought helplessly, "This child, really so mischievous—I wonder who she learned it from."

"Master." Xiao Bai Yue's tiny head peeked out from behind the white cloth and said, "Master, no peeking."

"Xiao Bai Yue, I wasn't planning to peek in the first place, but now that you've said that, I'm getting curious!"

Xiao Bai Yue puffed out her cheeks, looking just like a squirrel with its mouth stuffed full of food. "No, Master, you can't peek!"

"Fine, I won't peek. I wasn't planning to anyway."

"And no lewd thoughts either!"

"Alright, alright, whatever you say, you little rascal—hurry up and wash. We still have to return the basin to the landlady later!"

"Master, you big dummy—I'm not talking to you anymore, bleeh bleeh bleeh!" Xiao Bai Yue stuck out her tongue and made a face at Zero, then pulled her head back in and prepared to bathe.

After a short while, Xiao Bai Yue peeked through a gap in the white cloth and saw that Zero really was just sitting by the window in a daze, lost in thought.

"Hmph, Sister Luo Li was right after all—Master really is a big dummy, a big blockhead!" Xiao Bai Yue grumbled inwardly.

After her bath, Xiao Bai Yue put on the clothes Zero had prepared for her—a light, sleeveless dress. Honestly, she looked even cuter in it.

"Xiao Bai Yue, are you done washing?"

"Hmph!" Standing on the table, Xiao Bai Yue puffed out her cheeks, turned her head away, and only left her side profile facing Zero.

"What's wrong, Xiao Bai Yue? Why are you angry?" Zero picked Xiao Bai Yue up and held her in his palm.

"Master, you're a big dummy—a dummy, a dummy, a big dummy!"

"Oh? You dare scold me? Let's see how I punish you! Tickle tickle tickle~" Zero held Xiao Bai Yue in one hand and tickled her with the other.

"Hahaha, Mas…Master…stop…stop tickling, that tickles…hahaha…Xiao Bai Yue was wrong…Xiao Bai Yue knows she was wrong, Master…that tickles, hahaha…" Xiao Bai Yue rolled around nonstop on Zero's palm, but the hem of her dress also inadvertently revealed a glimpse of spring.

Zero: "…"

Xiao Bai Yue: "…"

"I'm sorry, Xiao Bai Yue, I…I didn't do it on purpose."

"N-no… it's fine, Master, I… I don't mind!"

The two of them noticed the air seemed a little awkward.

"Alright, you should rest early! I'm going to return the washbasin to the boss lady. We still need to keep gathering information about this world tomorrow."

"Mm…" Then Xiao Bai Yue floated up and flew toward the little nest Zero had prepared, getting ready to sleep.

"Good night, Master."

"Good night, Xiao Bai Yue."

……

Several days later, Zero and Xiao Bai Yue left that small town and hurried off to another place to continue gathering information about this world.

When passing through a village, night had already fallen, and they happened to encounter two "people"—to be precise, two ghosts.

"Master, be careful, those two are ghosts!" Xiao Bai Yue warned.

"So these are ghosts?" Zero looked at the two evil ghosts not far ahead.

One was a female ghost with two small horns on her forehead, silver-white medium-length hair drooping over her shoulders.

On each side of her face were two thick red bar tattoos; she wore a red kimono, looking quite cute. Her left eyeball was engraved with the characters "Lower Four."

The other was a male ghost with X marks on his forehead and on both sides of his cheeks, long ears with small earrings, and the characters "Lower Three" engraved on his left eye.

At that moment the two of them were gnawing on a corpse. When they raised their heads and saw a person standing before them, they immediately grew wary. Discovering it wasn't someone from the Demon Slayer Corps, they let out contemptuous sounds.

"Tch, so it's not someone from the Demon Slayer Corps. Then this is easy. Kill him and eat him, then let's get out of here. The Demon Slayer Corps people are probably on their way."

"But, if we fight him, I'm afraid…"

"Afraid of what? We're Lower Moon demons—taking down an ordinary person is a cinch. Yu Yu Lingzi, you're way too timid. I really don't know how you ever became a Lower Moon demon."

"F-fine…"

Seeing them, Zero immediately used his Analysis Glasses to analyze the information on the two ghosts.

【Analyzing… analysis successful】

【Lower Moon Four — Yu Yu Lingzi, a Lower Moon demon of the Twelve Demon Moons, one of Muzan Kibutsuji's direct subordinates. Timid by nature; upon encountering a Pillar-level swordsman of the Demon Slayer Corps, she immediately flees. Blood Demon Arts: Vine Manipulation, Puppet Control, Earth Evasion, Concealment of Aura.】

【Lower Moon Three — Byou Yaba, a Lower Moon demon of the Twelve Demon Moons, one of Muzan Kibutsuji's direct subordinates.

In life she was a ninja; in order to survive, she killed her own family members. After death she was granted Muzan's blood and became a demon. Blood Demon Arts: Withering, Maple Blade, Sacrificial Substitute Clone, Concealment.】

【Analysis Result: Decapitation with a Nichirin Blade forged from Scarlet Ore that absorbs sunlight can kill them; otherwise, decapitation with ordinary weapons will only allow instant regeneration.】

【Suggestion: Use the thermal energy generated by the Dark Alloy Type Four embedded with energy crystals to slay them. The thermal energy produced by the Dark Alloy Type Four has the same effect as a Nichirin Blade.】

"Lower Moon Three — Byou Yaba? Lower Moon Four — Yu Yu Lingzi? Why does that sound so familiar? Why do I feel like I've heard these somewhere before?"

"Didn't expect anyone to actually know the two of us. Then you can consider yourself dying a worthy death."

"Master, be careful underground, there's something!"

While Byou Yaba was speaking, Yu Yu Lingzi secretly manipulated vines to attack Zero from underground. With Xiao Bai Yue's warning, Zero reacted swiftly, leaping backward to dodge the attack.

"What is that little thing? It has neither human aura nor demon aura!" Yu Yu Lingzi said. If not for that little thing's warning just now, she would have definitely been able to grab him.

"You're the little thing! Your whole family are little things! I'm Master's…"

"Xiao Bai Yue, that's enough. Since they want to die, then grant their wish!"

"Yes, Master. Activating combat mode!" Xiao Bai Yue's eyes instantly changed color—one red, one blue. The red eye could analyze the combat process and combat mode; the blue eye could perform data analysis and scanning. An egg-shaped shield also appeared around her body.

This was designed by Zero, to protect Xiao Bai Yue from other attacks during combat.

"Buzz buzz buzz…" one after another, small drones flew out from the void—these were the Destroyer micro-drones Zero had released from his nano-space.

"Xiao Bai Yue, I've already transferred control of the drones to you. You go deal with that female ghost; the other one, leave to me."

"Yes, Master! Control transfer successful! Beginning combat, target: Lower Moon demon — Yu Yu Lingzi."

Then, under Xiao Bai Yue's control, the Destroyers attacked Yu Yu Lingzi.

"Dark Alloy Type Four!" Four black-and-red scabbard cases linked together flew out from the nano-space and attached to the position behind Zero's waist, with black hilts exposed at the bottom of each scabbard case. He drew one of the blades, inserted an energy crystal, and instantly the blade's edge emitted a dazzling red light,

"Little brat, now, it's just you and me!" Zero pointed the blade at Byou Yaba and said.

The instant Byou Yaba saw the red light radiating from the blade, cold sweat poured down his forehead. He could feel the threat the blade brought, and a sense of fear rose unbidden in his heart.

……
