What does it mean that the Demon King was killed by a wheelchair?

"Oh well, never mind that. Just remember this: this guy is absolutely terrifying, like he's immortal. Every time he closes his eyes at a crucial moment, he can instantly regain full strength and then crush his opponent!"

Lupin wiped the cold sweat from his brow: "Okay...okay, I'll remember that. What a terrifying guy."

House cleared his throat and continued, "Ahem... never mind, let's get back to what we were talking about. What's the name of that demon king you asked me to help you with?"

Lupin let out a soft breath: "[Demon Emperor] Alexandra Lenea."

House thought to himself, "I think I once singled out this name in Eternal World..."

Lupin straightened his collar: "Brother House, Lady Lenia sent me to you to make a deal."

"trade...?"

"To be frank, Lady Lenya needs you to kill the seven people in the world who share your identity, namely the seven heroes."

Why?

"Because these seven heroes are growing stronger every day, sooner or later they will threaten Lady Lenya's plans."

"Then why the hell didn't she go and kill him herself?"

"Because we can't beat them."

"..."

House's mouth gaped open, his brow furrowed, and he looked as if he had just eaten shit.

"No, I just wanted to ask, between this Demon Queen Lenia and the Border Collie, who do you think is more intelligent?"

"Uh... what's a Border Collie?"

"I just wanted to ask her if she's an idiot!"

House rolled his eyes, speechless with rage, and said, "She's a hero who couldn't even defeat a single demon king, and you want me to fight seven? Are you out of your mind? What were you thinking?!"

"She's less intelligent than a Border Collie, and I'm probably not even as strong as a Border Collie!"

Lupin gazed at the wisps of smoke rising from the distant woods, mentally calculating the time by fidgeting with his fingers:

"Brother House, you don't understand. It's not that Lady Lenia is weak, but that these heroes are too strong. These guys are messengers personally chosen and summoned by the gods, and each of them possesses divine pronouncements! Their terrifying and heaven-defying power is simply unbelievable! Not to mention, they are even from different dimensions."

House, embarrassed, said, "God's oracle? Can you please stop using such technical jargon and speak plainly? I only have a college diploma, I don't understand."

A tense look appeared on Lupin's face, as if merely describing the power of these heroes was enough to instill fear in people:

"...It's a kind of destiny-based power, which is very difficult to describe. Let me tell you an example."

"In fact, countless powerful individuals from Grayvalan have tried to challenge them in the past. At the beginning of the battle, they were often able to firmly suppress the heroes, and even almost killed them in one move."

"But somehow, as the battle progresses, these heroes always manage to stand up, shouting about bonds and friendship, and then launch a powerful counterattack, defeating their formidable enemies in one fell swoop!"

"And it's not an isolated case; almost all heroes possess this ability!"

House was deeply shocked.

What kind of divine decree is this...? This must be the protagonist's halo!

And what does it mean to have traveled from other dimensions? So these seven heroes are all transmigrators like him?

"But you're different!"

Lupin pointed at House, who was in a wheelchair, and said, "Brother House, you're a hero too! The divine power doesn't activate between heroes, so the best way to eliminate a hero is to find another one!"

House looked down at his crippled legs and his palms:

"Then...where is my divine oracle?"

"Huh? Of course you don't have one. A divine oracle can only exist if there is a god. You were summoned by the Demon King, so it's impossible for you to have such a thing as a divine oracle."

House frowned. "So you knew I came from another time?"

The other person nodded, but seeing that Lupin wasn't surprised at all, House found it a bit hard to understand:

"In your world, time travel isn't considered anything special anymore?"

Lupin went on and on about this for a long time.

But because there was too much nonsense, House summarized it himself.

In short, the world of Greyland is somewhat similar to D&D.

For them.

The so-called "time travel" is actually just opening a door from one dimension to another.

Like Lenya, she opened a door in Hell and came to Earth.

This is a "time travel" experience.

Of course, most people in this world don't really understand the concept of time travel, and what Lupin and he said is very little known information.

According to him, because the familiar race has almost no combat ability, the focus of training has always been on auxiliary functions such as knowledge acquisition and petty theft.

Having said so much and walked for so long, the sun was beginning to set, and this topic was about to come to an end.

House asked the question he most wanted to ask: "So, you said this is a deal, right? Then I want to ask, what benefit will I get from helping her do this?"

Lupin seemed to have been prepared to answer his question long ago:

"It's very simple, it's just this—heal your legs."

"!"

House immediately sat up straight in his wheelchair, his words hitting the nail on the head. This truly resonated with him, but he didn't believe it immediately. Instead, he pressed for more information:

"Besides her, is there really no one else in this vast world who can heal me?"

Seeing this, Lupin simply smiled and said, "Brother House, you're not a local of Grayvalan, so I don't blame you. Let me give you a little bit of information. Do you know what the mortality rate is for ordinary people once they contract the Magic Crystal Disease?"

House shook his head.

"It's 100%."

"This disease is the most incurable of incurable diseases; even the divine healing magic of the bishops of the Heavenly Society cannot cure it."

"hundred percent...?"

"That's right, but Lady Lenia is one of the exceptions among the hundreds of millions. She has a super magic she created herself, called the [Principle of Reversion]."

"?"

Radagan is Marika, right?

"What does that mean?"

Lupin scratched his beard and said, "This skill is amazing. I don't know the specific principle behind it, but I have definitely seen her use this magic to cure the magic crystal patient."

He rubbed his hands together. "She said it's a deal you can't refuse, because even if you search the entire Grayland, only she can use this magic to heal you."

"...Um."

House gave a brief reply, agreeing to the request.

It was called a transaction, but he really had no choice. But whatever, if all he could do was try to look on the bright side of things.

At least this way, I'll have a goal and hope.

Lupin chuckled. "Brother House, a wise choice!"

Squeak squeak...

As the wooden wheel rolled over a stone path, the conversation drew to a close, and the two finally arrived at their destination.

"We've arrived."

House looked towards the horizon; it was already sunset.

The sky at that moment resembled an overturned wine barrel, stained with a layer of dim yellow glaze.

House looked around and could vaguely see some low wooden houses and thatched roofs scattered about, with crooked chimneys emitting thin wisps of gray smoke that rose in the twilight.

The rough stone-paved road stretched out in the shadows, with haystacks piled up along the roadside and worn wooden wheel tracks imprinted on them. The townspeople hurried along, their figures wrapped in coarse linen clothes swaying through the narrow alleys, herding bleating sheep back to their pens, or carrying hoes and rushing home.

House was about to say how wonderful the customs and culture of this other world were when suddenly, a sharp pain shot through his temple! It felt as if an arrow had pierced his brain and smashed it to pieces. The pain made House tremble violently, and cold sweat poured down his face.

"...?"

But the pain lasted for less than a second before disappearing without a trace, leaving House wondering if he was hallucinating... However, Lupin next to him seemed completely unaffected, even humming a little tune.

Lupin shook his wrist and said, "Alright, House, it's about time. We familiars have time limits for our activities outside. I've done my job as your guide. As for what's next... I've found you a job in this village. You can rest and recuperate here for a while."

"Yelo Village is safe, so don't worry about those monsters. But remember one thing: never tell anyone that you are a hero... The residents here are not as easy to talk to as I am."

House hadn't even reacted yet when he shuddered: "You're leaving already?"

Lupin nodded: "Hmm, a familiar's time is precious, I have other things to do~"

"Wait! There's one more thing. I have a question for you. If I want to learn magic, where should I go to learn it?"

Indeed, based on House's own deductions, practicing swordsmanship was clearly not a good path. As a disabled person, he was better off using long-range methods, but archery also required leg strength, so it wouldn't work. Therefore, there was only one answer left.

That is—magic.

Lupin crossed his arms and didn't answer immediately. He led House to a cozy wooden house.

The room wasn't large, and there was no signboard. A faint fragrance wafted through the air as you approached. Warm orange light shone through the paper windows, and various flowers and plants grew in front of the walnut wood door.

"Magic... Generally speaking, there are two ways to learn it: one is to enter a magic academy, and the other is to find a private tutor. But both of these are quite expensive, and magic is an ability that relies heavily on talent. I think you should practice swordsmanship instead, Brother House."

As he spoke, Lupin yelled and swung his arms wildly, finally wiping his nose with his thumb:

"I just saw you swinging your leg really hard, quite impressively."

House thought to himself, speechless, "Magic relies on talent, but does that mean swordsmanship doesn't...?"

Everyone else starts from 0, but I'm starting from a negative number.

"It's alright, thank you for telling me. Oh... by the way," House slid his wheelchair over, "Do you know magic?"

Lupin was stunned for a few seconds, but the next second his monkey face suddenly became incredibly resolute.

He opened his right palm and picked up two pebbles from the ground, placing them in his hand.

"Brother House, I feel that we are quite destined to meet, so I will make an exception and show you the only magic technique I know, which I have practiced for ten years."

"Although I'm not good at fighting, I'm confident that if this move of mine hits, it can instantly kill at least 50% of the opponents in the world!"

House's breathing slowed down:

"Really...?"

"Hmph..." Lupin's lips curled up in a mysterious way.

"Just you wait and see... Oh~~ Mmm~~ Drink up!!!!"

With a howl that seemed to indicate a constipation that had lasted for thirty years had finally been relieved, amidst Lupin's earth-shattering roar... the two pebbles in his palm twisted and turned, switching positions.

House: "..."

He silently rubbed his forehead: "Are you fucking serious...? The ability to wipe out half of humanity is just making two pebbles twist once?"

Lupin, completely unfazed by House's mockery, said, "Brother House, my move is called—[The Fall of a Billion Lives]."

House maintained his nonchalant expression: "So what... the name is so..."

「!?」

But suddenly! It was as if a bolt of lightning struck House's brain!

He sat up abruptly, his facial features contorting instantly, and goosebumps erupted all over his back.

As he went through the meaning of the name in his mind, he seemed to understand what the skill meant...

The two pebbles switched places.

So what if... it were used on a person?

Especially in men?

No wonder it's a move that can defeat '50 percent of the world's population,' so that's what it means!

"Holy crap...that's terrifying! How the hell did you come up with such a vicious move?!"

Lupin just chuckled, hands on his hips, "Heh, it's just a self-protection trick I came up with. It's a family secret, not to be passed on to outsiders."

"Holy crap, no way, Coach, I want to learn this! It's amazing!"

Lupin shook his head smugly and knocked on the door: "Alright, House, see you again sometime. The job I've arranged for you is right here. Good luck on your journey ahead!"

After saying this, Lupin bowed one last time, then gracefully moved away and walked away.

With a creak, the door opened, and out stepped a curly-haired, purple-haired girl. She wore thick, round glasses and had a cute face, but her figure could only be described as grotesque.

"Oh... a man with the magic crystal disease in his legs."

She bit her finger and said, "You must be Mr. House... Hehe, my name is Omia, Mr. Lupin mentioned you to me."

She opened the door and respectfully invited House inside. House was somewhat stunned as he looked at the refined girl in front of him. After all, he had never had much opportunity to interact with women in his previous life, and he had never done any research on matters of the heart.

He glanced back at the last moment before entering, but the monkey-faced figure had vanished.

Lupin... While there's a bit of a stereotype involved, to be honest, House himself was prepared to be tricked by him.

But in the end, it turned out that I had judged people by their appearance.

He fulfilled his mission as a familiar perfectly.

The memory of being rescued by the other party flashed through his mind, and House felt a little disappointed at the thought of not knowing when he would see this guy again.

"Here, have some water."

Omia brought a glass of water to House, who looked at the glass and noticed it seemed to be tilting slightly to the left.

Moreover, it's not just the water glass; the pages of the books, utensils, and other items on this table are all slightly tilted to the left.

House looked down and saw that one of the table legs was shorter than the other.

But he didn't pay much attention. He picked up the cup, drank the water the other person handed him, and briefly looked around the room.

The two were currently in the living room, which was filled with potted plants and flowers. House didn't recognize any of these plants, and they were all colorful, so they didn't look like ordinary plants.

And... the sharp-eyed House also noticed a set of dark blue robes and a large wizard's hat placed in the corner of the room.

"Thank you, Miss Omia."

"Hehe... It's nothing, Mr. House. I'm the one who should thank you. From now on, this apothecary shop will depend on our joint efforts to make a living."

Omia nodded gently and smiled, a smile that was simply angelic. Then the other party handed her two more sheets of paper.

"This is a letter Mr. Lupin left for you, and this is an agreement. Please sign it."

House nodded, glanced at the letter briefly, and decided to read it later.

As for the agreement... are all other worlds this rule-abiding now? Do you really need to sign a contract?

But Lupin really found himself a great job... a potion shop, that's a really good job.

House smiled slightly at the thought that he could not only hone his skills and learn some knowledge, but also not be too tired.

Although the start was terrible, the people I met were all pretty good.

"Hmm, the agreement... let me take a look..."

But the next second House's expression suddenly froze.

"Um?"

The title of the agreement was written in bold, powerful characters, and it read:

Slave Contract: House the Experimenter

"...?"

"What the hell is this? A slave contract?!"

Omia smiled slightly: "Hmm? Didn't your brother tell you?"

House was completely bewildered again: "What the hell? My brother? Where did I get a brother?"

"Oh right? Isn't that Mr. Lupin? Isn't he your brother?"

"?"

Omia's face suddenly flushed for some reason. She narrowed her eyes slightly, licked her lips, and cupped her face in her hands: "Your brother sold you to me... From now on, you will be my slave forever..."

In that instant... House was astonished to see what was flashing in the girl's pupils.

That's a pink heart.
