"Demon"

Muzan regretted it!

He really regretted it!

He shouldn't have even dreamed of teaching anyone medicine!

Not a single one of these three brats was studying properly!

The stories in novels where you just pick up some girl or kid and they become a genius disciple were impossible!

He couldn't teach them, he really couldn't teach them.

They couldn't even recognize characters, and they wouldn't study properly when taught. All they did was run around everywhere, wanting to touch everything they saw. They almost broke the ceramic pot he used for brewing medicine!

Teach? Teach what nonsense!

The afternoon after he agreed to teach them how to cure illnesses, Muzan had just finished brewing some cold medicine for a neighbor. When he returned to his room, he found the three brats standing uneasily in the corner.

On the wooden shelf behind them, the bottles and jars were untouched. Muzan frowned, "What did you do now?"

The three children chuckled awkwardly, glanced at each other, and then slowly moved aside.

Behind them was the medicine Muzan had brewed for Mr. Ikumura, who had a sore throat. The container had been smashed, and the medicine was spilled all over the floor.

Muzan's first reaction was anger, but then his eyes lost their light. Finally, he let out a long sigh, moved aside to let them out, and said, "Alright, you can go. I'm not skilled enough, I can't teach you."

"Uncle, please give us another chance! We know we were wrong!"

The three children put on pitiful faces. As a Maneating Demon, Muzan was unmoved by their pleas. He grabbed them by the scruff of their necks and tossed them out the door one by one.

The three little ones: இ௰இ

Muzan: (￣_￣)

He closed the door. Seeing that Mr. Ikumura would soon come to pick up his medicine, Muzan sighed and started brewing it again. Next time I move, I won't be a physician. It's not suitable for slacking off.

As he was re-brewing the medicine, Mr. Ikumura's voice came from outside. Though a bit hoarse, he sounded energetic.

"Yo, you three bothering the physician again? Got kicked out?"

Mr. Ikumura lifted the curtain and walked into Muzan's house. "Physician, I'm here to pick up my medicine."

Muzan continued his work. "Those three kids knocked over your medicine. I'm brewing it again, so wait a bit if you're not in a hurry."

Mr. Ikumura found a place to sit, leaned against the wooden wall, crossed his legs, and chatted idly.

"By the way, it's been over ten years, how are you still so young?"

Muzan glanced at him. "Good skincare. I don't look old. What's wrong? Do you, a grown man, want to take care of your skin?"

"My wife and family are always asking me how you maintain yourself."

"Sleep less, exercise more."

Muzan poured the scalding medicine into a jar and handed it to Mr. Ikumura. "Remember to return the jar after you use it."

"No problem."

After seeing Mr. Ikumura off, Muzan lay back on the recliner in his room. More exercise is impossible. I'm too lazy.

Could the great Demon King really rely on simple exercise to strengthen himself?

Yes! Maximum slacking!

As night fell, Muzan listlessly picked up a book and lay down on the rocking chair outside the door, enjoying the evening breeze.

It was fortunate he wasn't human. In this era, there were no air conditioners or fans. In the sweltering summer heat, only fans and the evening breeze could offer any coolness.

While enjoying the cool breeze, Muzan suddenly caught sight of a dark shadow flashing by in the distance. Immediately after, screams erupted from the direction the shadow had disappeared.

Muzan frowned and slowly got up from his chair. He saw people already running past him in terror. Someone noticed Muzan, who hadn't run yet, and yelled, "Run! A demon is out eating people!"

Muzan: "???"

What? I didn't know about this?

Muzan broke free from the person. "You go first."

Search by book title not found, you can try searching by author, maybe the name has changed!

He then walked in the opposite direction.

The person hurriedly chased after him but couldn't catch up. They turned back in frustration and continued to flee.

Muzan leaped onto the roof and quickly arrived at the scene.

He hadn't sensed any of his demons nearby!

Besides, his subordinate demons wouldn't just pick a random village to start feeding.

Standing on the roof, Muzan saw a monstrous, grotesque creature with sharp, long claws. Its crimson eyes and the sharp teeth in its mouth seemed to indicate its identity – a Maneating Demon.

Everyone who had fallen behind was torn apart from behind with a single claw. But strangely, this thing only killed people and seemed uninterested in the food it had already obtained.

Moreover, Muzan didn't know about this creature among his demons. It was incredibly ugly, with blurred features, and was definitely not one of his subordinates.

And in the Scum Boss's memory, he hadn't created a demon like this.

Muzan landed, kicked the creature that looked like a demon but wasn't, and turned to the villager who had almost been killed. "What are you looking at? Hurry up and run!"

The villagers silently swallowed, scrambled to their feet, and fled for their lives.

This ageless physician is truly a hidden master!

Muzan looked at the... creature he had kicked flying.

Because he had deliberately controlled his strength, he had only kicked it away, injuring it upon impact, not killed it outright.

This thing seemed to possess some intelligence, yet wasn't particularly bright. It could already sense Muzan's overwhelming power, enough to crush it. It struggled to get up, trying to escape.

Muzan took a step, appearing directly in front of it, and stomped down hard on its head.

"Wuwu~"

The monster, pinned under his foot, whimpered as if begging for mercy. Muzan's fingernails elongated, and he plunged one into its head.

After becoming a demon, a demon's memories could be read and even arbitrarily altered by Muzan.

Muzan wanted to see this thing's memories.

This is truly strange. Nothing like this weird thing appeared in the original story.

As Muzan's blood invaded its body, the strange creature roared in pain, but Muzan kept it firmly pinned beneath his foot, thrashing like a beached fish.

Muzan flipped through its memories. He withdrew his foot and took a step back. The screaming creature suddenly exploded, splattering gore everywhere.

Muzan felt around the ground under his foot a few times, took out a cloth to wipe his fingers, and unhurriedly walked home.

This thing didn't have many memories. It didn't have much intelligence to begin with, so it didn't remember much.

It seemed to have been implanted with certain thoughts: it only knew it was a demon, it had to kill people, if it saw someone wearing Demon Slayer Corps uniform, it had to eat people, and it couldn't be out in the sun.

It had to run away from other man-eating demons.

Interesting.

Could it be that this world was no longer the world of Demon Slayer he knew?

Were there other forces at play?

What were they trying to do?

Ruin his reputation?

He thought about how, for decades, the fear of man-eating demons had been ever-present, even spreading beyond Tokyo. Yet, the demons under his command had never wantonly killed people.

The Demon Slayer Corps still had so many members. It seemed it wasn't a matter of insufficient time, but that something else was at play behind the scenes.

Muzan washed his hands, a smile spreading across his face.

Interesting, very interesting.

In the Scum Boss's centuries of memories, there were no mysterious powers other than demons.

Was it a butterfly effect caused by his transmigration, or was it a more terrifying existence?

The people in this village should all know by now that he wasn't an ordinary person. He hadn't hidden any of his actions just now.

It was time to move, and while he was at it, he would thoroughly investigate what this thing, which was like a demon but not quite, actually was.
