Demon Slayer: I am a Demon.

Su Mu patted Tanjiro on the shoulder: "Your nose is far more sensitive than you think. You can smell all sorts of scents, right? Not only that, you can smell other things too, like joy, like sadness..."

"Therefore, you should be able to feel the sadness of the dead demons. That is why, after Fujikasayama slayed the demons, you went forward to smooth the unseeing eyes of those dead demons."

"Because you can feel the sadness of these ghosts and understand the pain they once suffered, that's why you do these things."

"The fact that your nose can smell things that others cannot has already shown your uniqueness. Therefore, you will also be able to smell the flaws in this stone."

"in this way……"

"Then you will be able to cut through the huge rock in front of you."

Su Mu explained softly, encouraging the boy in front of him.

Tanjiro gripped the hilt of his sword, stared at the enormous rock before him, and tried to sniff his nose.

His nose was very sensitive; he could smell all sorts of scents in the air: the scent of the wind blowing through the leaves, the unbelievable scent of Makomo's pounding heart beside him, and the scent of the huge rock in front of him.

However, no clues were found in this huge rock.

"What exactly is this so-called 'line of weakness'? How can I detect it?"

Tanjiro wanted to ask the master, but the master also said that it was something he couldn't do either.

He can only rely on himself.

"So, how can I detect that clue?"

The boy stood before the boulder, closed his eyes, and tried to sense everything, but what exactly was the aura of that so-called line of weakness?

…………

Seeing Tanjiro deep in thought in front of the boulder, Su Mu did not disturb him but quietly left.

Makomo glanced at Tanjiro, who was standing there with his eyes closed, deep in thought, and then followed her teacher.

As the two walked down the street, Makomo couldn't help but ask:

"Sir, is it really possible to detect the so-called 'line of weakness' by smelling it?"

Su Mu stopped and looked at Makomo: "Perhaps others cannot do it, but Tanjiro should be able to."

"why?"

Makomo was puzzled: "Is it because Tanjiro's nose is sensitive enough?"

"Perhaps that's part of the reason, but I feel that Tanjiro should have a heart that is close to nature, a very sensitive mind."

Su Mu shared his thoughts.

Makomo couldn't understand and couldn't help but turn around to look at the boy standing under the boulder with his eyes closed. Could he really smell the so-called 'line of weakness'?

"Can I do that?"

Makomo turned around and looked at Su Mu.

"I don't know that, after all, your nose isn't very sensitive."

As he spoke, Su Mu pointed to the nose beneath the girl's mask.

Makomo was surprised and somewhat troubled: "Then how can I cut through the boulder?"

How would I know that?

Su Mu shook his head.

"Sir, you can tell from Tanjiro's keen sense of smell that he can sniff out the so-called flaw. So, from what angle do you think I can look for that flaw?"

As she spoke, Makomo pointed to her eyes: "Is my eye okay?"

"Makomo's eyes are beautiful, but they don't seem any different from ordinary people's. If it were Kanao, her eyes would be amazing, capable of dynamic vision. If it were Kanao, perhaps..."

"Then, sir, where do you think I should begin?"

"Well... I'm not quite sure either."

"If the gentleman can show Tanjiro how to cut through the boulder, then why can't I?"

The girl bit her lip slightly, her eyes filled with a hint of resentment.

Su Mu naturally couldn't tell him that this was something Tanjiro would be able to do in the future.

If I remember correctly, Tanjiro first smelled the thread of weakness during his duel with Sabito. He smelled the 'fatal' thread, which allowed him to cut through the huge rock along the thread. He also used the thread of weakness to sever the head of the Hand Demon.

As for Makomo, this girl who was supposed to die at the hands of the Hand Demon, I didn't know much about her.

However, he obviously couldn't tell Makomo these things, so after a slight hesitation, he could only explain, "Perhaps it's because I don't know Makomo well enough?"

"I don't know much about it."

Makomo murmured those words, then couldn't help but look up at the man: "Then what do you want to know? Tell me, and I'll tell you."

"You can tell me anything you want to know, sir."

"As long as you want to know, sir."

After saying that, feeling that she had said something a bit too ambiguous, Makomo immediately lowered her head. The mask concealed her face, so it was impossible to see what her expression was like, but judging from the rosy ears peeking out from between her black hair, Makomo's face must have been very red.

Su Mu was in a dilemma. No matter how well he knew Makomo, he didn't know how to get Makomo to find any clues or weaknesses. In Demon Slayer, this was something that Tanjiro could almost exclusively control.

"Do you really... want me to get to know you?"

Su Mu stared at Makomo and asked in a low voice.

"Ah."

Makomo nodded immediately, her head lowered, a blush spreading across her pretty face. At that moment, she was already thinking about how she should answer if her master asked her some very private questions.

But no matter how shy she was, she would have to tell her husband if he wanted to find out.

…………

After training for a while, Nezuko realized that her brother and teacher were gone, so she stopped training and, after asking a few people nearby, walked in the direction where her teacher and brother had left.

After walking for a short while, they came across two people standing in the road.

I also saw Makomo shyly lowering her head.

With a woman's keen intuition, she immediately sensed that Makomo's feelings for the man were somewhat unusual.

Unlike how most girls treat boys.

How could someone look so shy and coy, like a little vixen who's playing hard to get?

This made Nezuko feel a little annoyed.

As for Mr., Nezuko didn't think anything of it. It's normal for a guy as outstanding as Mr. to be liked by girls.

Chapter 169 Lower Moon Two. Pero

Nezuko's sudden visit disrupted the tranquil atmosphere, and the three of them walked back together.

Makomo was still lost in her fantasy of how she should show her husband more private things if he wanted to know them.

As Nezuko walked along, she tilted her head and looked at Makomo, who seemed to be in a daze. A sense of crisis welled up in Nezuko's heart.

夜

It is unknown when it will arrive.

Bustling Tokyo remains vibrant and prosperous.

Wearing a military cap with a wolf head badge and a black cloak, the man walked quietly on the dark road. His hair had several triangular bangs connected together on both sides, and there were triangular patterns on the top and sides of his face.

The man's lowered, scarlet eyes had a black sclera on one eye, while the word "Xia San" was etched on the iris of his left eye.

"pat..."

The military boots made a dull thud on the floor, and the man suddenly stopped.

Before anyone knew it, seven or eight figures had appeared on the road ahead. The moonlight shone on their backs, making the words "evil spirit" and "annihilation" very clear.

Upon seeing the man who had stopped in place, these people silently drew their Nichirin Blades.

The blades were drawn, their gleaming light reflecting off the resolute faces of these men, and their eyes filled with hatred.

"The Demon Slayer Corps' swordsmen!"

The man spoke softly, his head still bowed, his voice calm: "Are you still using such outdated weapons?"

"No matter how skillful your swordsmanship is, it's useless now!"

No one responded to the man. Accompanied by silent, rapidly advancing figures, these people approached the man before them at a speed far exceeding that of humans, wielding their sharp Nichirin Blades under the moonlight.

"boom!"

A muffled volley of gunfire rang out, and a man who had been advancing rapidly in silence collapsed, dying without resistance on his journey.

Year after year, he trained hard in swordsmanship, but under the firearms, he was almost powerless to fight back.

The man also raised his head at that moment, blew on the smoking musket in his hand, and looked at the Demon Slayer Corps swordsmen who were still closing in, a mocking smile on his lips: "Brave swordsmen! Times have changed."

As the man spoke, he pulled out two Nambu Type A pistols from his waist.

"Bang...bang."

A series of gunshots rang out, and two more swordsmen collapsed to the ground.

At this moment, two swordsmen approached the man, their Nichirin Blades flashing with sharp light in the night as they slashed at him, but he easily dodged them.

In an instant, the man reloaded the musket.

The heavy military boots pounded on the ground. As the man retreated and dodged another knife, his white-gloved fingers gently pulled the trigger.

"Bang, bang..."

The musket bullets burst forth, easily piercing the swordsman's forehead and ending the life of a swordsman who had trained for many years.

"Bang bang..."

A series of muffled sounds echoed through the night sky as swordsmen fell to the ground one after another.

finally

On this dark street, only the man stood quietly on the blood-stained ground, unharmed.
