Demon Slayer: The Demon King is actually a weak girl?!

Unexpectedly, Miss Li pushed Wuzan away.

"Big liar!" Miss Li pointed at Wuzan, suppressing her anger because of her daughter's presence, "Then what's with the perfume on you? It's not my perfume at all, you smell like another woman's perfume!"

Muzan was stunned for a moment, and suddenly remembered that he might have applied too much ointment when he was in the form of a geisha.

If a person stays in a certain scented environment for a long time, it is easy for him to lose the ability to smell the scent.

"Ah, that was a mistake."

but……

“Maybe I didn’t take her seriously enough.”

If he really cared about her, he wouldn't have thought of looking for her until now.

Despite this, Wuzan still looked sincere: "Miss Li, please believe me, those are perfume samples from the client company, I just took them and sprayed them twice."

"No need to say more." Miss Li turned her face away, "Mr. Yueyan, let's break up."

Wuzhan: “…”

So, could it be said that...

He was dumped?

The little girl pointed at Wuzan angrily and scolded: "Bad dad, you make mom sad, you are not my dad, I want to find a new dad!"

"A-jun, stop messing around." Wuzan said as he stepped forward to hold Miss Li's hand, but she dodged him directly.

Miss Li walked to the cabinet, opened the drawer, and took out a red velvet gift box from the drawer.

She handed the gift box to Wuzan.

Wuzan opened it and found a diamond ring the size of a pigeon egg with exquisite design inside.

Miss Li looked at Muzan and said seriously, "Mr. Yueyan, this is the ring you gave me half a year ago. Although I accepted your proposal, we haven't held a wedding ceremony yet, nor have we gone to the district office to get the marriage certificate. So, I will return this ring to you, and we'll call it a day."

Wuzan looked at Miss Li, then at the diamond ring in his hand, and was completely stunned.

Why did he break up?

***

This plot has been changed a bit.

According to the book, two years later, after Tanjiro became a member of the Demon Slayer Corps, one of his missions brought him to Asakusa.

It was also here that Tanjiro and the big boss Muzan Kibutsuji came face to face.

The situation at that time was that Muzan Kibutsuji was playing the pseudonym of "Mr. Tsukihiko" and was with Miss Rei and A-jun.

But now, Muzan has been dumped by Miss Li "two years ago" when the main storyline began...

“Never mind, when Tanjiro comes here two years from now, he won’t encounter anything.

Let him miss it."

Although Muzan had no feelings for Miss Li, he had played the role of her husband for a long time in his previous two lives. He was dumped so suddenly that he was more or less depressed.

The streets are full of people now, and Boss Xia can't show up. Otherwise, he really wants to hear what Boss Xia thinks about this matter.

I walked on the street in a daze, and the hustle and bustle around me seemed to have nothing to do with me.

This bustling and noisy world has separated me from you without me realizing it.

Suddenly, Wuzan stopped.

"There's a ghost smell."

He raised his head slightly and scanned the surrounding environment.

——That ghost was beyond his control.

"Oh, I know who it is."

With an evil smile on his lips, Muzan walked to a corner where no one was paying attention and summoned Mingnu over.

"clang--!"

Accompanied by the sound of strings, Mingnu appeared opposite Muzan holding a pipa.

Mingnu raised her crimson rose-colored eyes and looked at Muzan in confusion: "Master Muzan?"

"Mingnu." Muzan pointed in the direction of the ghost energy, "Now summon a low-level ghost for me and place it where my finger is."

Mingnu frowned slightly.

Although she felt a little strange, she didn't ask any more questions and just obeyed.

"clang--!"

After the sound of the pipa, as expected, people's screams were heard in front.

——That’s for sure.

If a "crazy ape" suddenly appeared on the street, who would not scream when seeing it?

But Mingnu really can't figure out Muzan-sama's thoughts and motives...

Wuzan just smiled softly, then looked at Mingnu tenderly and said, "Use your blood demon technique to explore the rat's nest over there, and we will wait here first."

"..." Mingnu stared blankly at Muzan's handsome profile, then slowly looked away.

"Master Muzan... smiled at me?"

The sounds of commotion in the distance were overwhelming.

Suddenly, everything seemed quiet again.

Muzan turned around and snapped his fingers at Mingnu: "Mingnu, let's go over there."

He walked forward a few steps, and suddenly found that the person behind him had not caught up, so he turned back.

"Mingnu?"

I saw Mingnu standing there stupidly with her head down, holding her pipa, not knowing what she was thinking.

After a few seconds, she came to her senses as if awakened from a dream: "Yes, Lord Muzan."

"..." Wuzan glanced at her and said, "Let's go."

"Yes."

"Why does this Ming girl seem to have a long reaction time?"

Wuzan thought in his heart.

……

A man and a woman walked to the "crime scene" where they had just committed the crime. They saw countless smoke with gorgeous flowers floating in the air, as if they were in a dream garden, magnificent and beautiful.

If nothing unexpected happens, it should be Tamayo's blood demon art.

"Have you seen them?" Muzan asked Mingnu.

Mingnu hugged the pipa tightly and nodded seriously.

"Then," the malicious smile rose again, "let's teleport them both a thousand miles away now."

"Yes, Master Wuhan."

……

"clang--!!"

***

A strange sound of a pipa pierced the air. Tamayo raised her head vigilantly. Just as she was about to remind Yushiro, she found that there was nothing under them and they appeared out of thin air above a rice field in an unknown countryside.

The next second, there were two "splash" sounds, and both of them fell into the water in the rice field.

"What's going on?" Yushiro almost wanted to curse, "Lord Tamayo, are you okay?"

"..." Zhu Shi was speechless for a moment, and felt completely unwell.

She had been a ghost for hundreds of years, and had never been treated so cruelly by anyone.

Her once meticulously done bun was now in disarray, and her clean and respectable kimono was covered in mud.

"Yushiro, where is my hairpin?" Tamayo touched her hair.

Yushiro immediately jumped into the water: "Master Tamayo... Gululu... I will find it for you right away... Gululu..."

Zhu Shi couldn't bear it: "No need, let's get out first."

"No, I must find your important hairpin, Master Tamayo! Gurgle..."

"..." Zhu Shi frowned and said nothing.

What exactly is going on?

The two of them suddenly came here, there was no doubt that they were under the influence of vampire magic.

I have always been cautious. If Yushiro had not suddenly encountered a ghost on the street and then contacted me quickly, I would not have performed blood demon magic openly on the street.

“Have I been seen through…?”

——Could it be Muzan Kibutsuji?

"No, it can't be him..."

Tamayo immediately shook her head again.

If it was Muzan, he would have killed me long ago, or at least captured me. There is no way he would be so merciful as to spare my life and send me here.

It seems that it is just another ghost causing trouble.

"Yushiro," Tamayo fixed her hair, "Don't look for the hairpin anymore, let's go back and pack our things and leave quickly."

The house where they have been living contains a lot of valuable information...

***

Tamayo residence in Asakusa, Tokyo.

Muzan didn't have the key, so he had to let Mingnu use blood demon magic to teleport them directly in.

This house is similar to Miss Li's house, both are typical Western-style buildings.

During the Taisho period, an important historical node in the fusion of Eastern and Western cultures, such Western things became more and more common.

The whole of Japan is slowly becoming westernized.

Tamayo's villa is very large, with a laboratory, a study, and many unnamed rooms.

Various chemical instruments were placed on the table in the laboratory - test tubes, measuring cups, alcohol lamps, and a microscope imported from Germany that looked very high-end.

"I have these things, so I won't take them." Muzan's voice was low and mellow, and full of charm. "As for the rest, Mingnu, you have to empty them out for me."

The man's pleasant voice reached Mingnu's ears, and Mingnu lowered her eyebrows and nodded: "Yes, Lord Muzan."

"Meow-"

Suddenly, she heard a cat's meow. Mingnu looked up and saw that a beautiful calico cat had appeared in Wuzan's hand.

Muzan casually threw the cat to Mingnu and said, "Take this cat away as well."

“…Yes, Master Muzan.”

"clang--!"

***

In this way, Muzan brought Mingnu and looted all the information in Tamayo's villa.

After everyone moved to the Infinite Castle, Muzan changed back into women's clothes and asked Mingnu to summon the Swamp Oni again.

The swamp ghost, with his long blue-purple hair like a strip of cloth, knelt on the ground and paid homage to the Lord Ghost King.

This swamp demon is exactly the target that Tanjiro is supposed to kill in the mission assigned by the Demon Slayer Corps in the book. It is also because of the swamp demon that Tanjiro's story is led from the remote countryside to the prosperous Asakusa, where he meets Muzan and gets to know Tamayo.

Because the original owner, Muzan, rarely went to remote areas.

He wants a suit and tie, he wants lots of flowers.

He wants to be respectable.

"As expected of me."

His cold eyes swept over the two funny horns on the Swamp Ghost's head, and Wuzan opened his red lips slightly: "Call out those three humans."

"Yes, Master Wuhan."

The swamp ghost activated the blood ghost technique, and the dry wooden floor began to make bubbling sounds like rice cake dough.

As these teeth-grinding sounds rang out, dark shadows began to appear on the ground, and three humans, whose faces had long been frightened pale, slowly emerged from underground.

These three people were the ones who had harassed Wuzan in the alley earlier.

"You...you are not a human..." Xiao Ba pointed at Muzan, who was dressed as a geisha. His face was already as pale as paper.

"Shh~" With her slender fingers in front of her lips, Wuzan's red lips slightly curved, and she smiled sweetly, "This kind of thing, even if you notice it, you can't say it out loud."

“Ahhh…” The woman next to Xiao Ba was shaking all over as if she had just stepped out of icy water. “Xiao Ba, are we going to die…”

Among the three, only the strong man remained silent because he was so scared that he lost his voice.

Muzan lazily blinked his thick eyelashes that looked like butterfly wings, and it was hard to tell whether it was happy or angry in his eyes: "Mina, call Kokushibo and Nightmare for me."

"Yes, Master Wuhan."

"clang--!"

Mingnu flicked her right wrist, and the next moment, two confused men appeared in front of them.

Xiao Ba on the ground screamed in fear: "Ahhh, this guy has six eyes, a monster!"

Kokushibo was no longer surprised by this, but he still glared at the yelling Xiaohachi with dissatisfaction.

Xiao Ba gasped and fainted.

Kokushibo turned around and said, "Greetings, Master Muzan."

Nightmare also knelt down and said, "Greetings, Master Muzan."

Muzan said "hmm", then pointed at the "Book Mountain" behind him and said to them: "Kuroshibo, you were born in a samurai family, so you must be a cultured person, right? And you, Nightmare, were a doctor, so you should be considered an intellectual, although you are a bit black-hearted."

Two blushes appeared on Nightmare's face: "Yes, Master Muzan, I like to see others die in pain the most. I also like to listen to everyone's last words."

"I am indeed well-read." Kokushibo replied in a low voice.

"Hmm." Wuzan smiled with satisfaction. "Can you guys find out for me if there is any method in this book that can make ghosts taste human food? Or a method that can turn ghosts into humans would be fine."

Black Death & Nightmare: "..."

With so many books, how long will it take to find them?

……

They searched for the entire night but still couldn't understand anything.

The book contains some human medical knowledge, such as how animal cells are divided into cell membrane, cytoplasm, nucleus, mitochondria, the functions of glial cells, and antiviral drugs, such as oseltamivir phosphate, Chiqiao Qingre Granules, etc.

How many years have they not used these? It's like reading a book from heaven, they don't understand anything.

Muzan was immediately furious: "Two idiots! Nightmare, are you considered a doctor?"

Nightmare said silently, "Lord Muzan, I'm sorry I couldn't help. If you're willing to wait for me, I can brush up on my knowledge of internal medicine."

"Forget it." Muzan walked over to the three of them and kicked them awake. "Nightmare, I appoint you as the temporary team leader. You and Kokushibo, the three humans, copy all these books for me. If you don't have enough people, you can also call some low-level ghosts who can read and punctuate. After copying all the books, Mingnu, you return all the books to their original places. And the kitten, tell it to contact Tamayo to get the books."

Nightmare and Naruto nodded, "Yes, Lord Muzan."

"By the way, I remember that Xiang Kai from Lower String Lu used to be a novelist?"

Nightmare was slightly stunned: "Him? Doesn't he only know how to play drums?"

"..." Muzan glanced at him and said, "Forget it, you don't know. Mingnu, you should also call Xiangkai to help. Well, I have something else to do, so I'll leave first."

The ghosts bowed their heads and said, "Farewell, Master Muzan."

"clang--!"

Mingnu stopped talking and sent Muzan back to the dense forest mountain.

……

After returning to the dense forest mountain, Muzan continued her training career...

***

A month later, the weather gradually warmed up.

In spring, flowers bloom and green leaves provide shade.

Before he knew it, Abeshi's student life had come to an end, and the day for the selection at Fujikiyama had arrived.

Muzan already knew the rules of Fujikiyama's selection from the novel, but she and Abeshi still listened to Gotanda Shirou repeating them again:

“It takes two days to walk to Tengxi Mountain from here. I have already drawn a map for you. Just follow what I wrote.

"The selection rules are to survive for seven days on a mountain full of ghosts. Whether you will encounter a stronger ghost and die, or just happen to not encounter a stronger ghost and survive, it all depends on your luck.

"Anyway, as long as you don't do what the previous Water Pillar's apprentice did before, foolishly killing all the ghosts in the mountain by yourself, but in the end you collapsed due to lack of physical strength and poor weapons, and instead save all the other members... that's fine."

Gotanda Shirou ate a piece of mushroom and continued,

"It's not good to be such a good guy. Because even if you save people who should have died now, they will continue to die in the missions they receive later."
