Start with Demon Slayer and create the strongest demon sword!.

Tanjiro looked at his hands in disbelief for a moment, and when he came to his senses, he hurriedly asked.

"Ajuramaru, what did you just do to me?"

Hearing this, Lin Fan replied calmly.

“This is one of my abilities. Whenever you kill a ghost in the future, I can digest its power and feed it back to you.

So if you want to become stronger, go kill ghosts..."

After a brief explanation.

Lin Fan also clearly felt Tanjiro's strengthening through his body's ability to control this, if converted.

The 30% just returned is probably equivalent to Tanjiro's hard training for half a month, and his body has been enhanced in all aspects.

But Lin Fan still had a question.

"System, are there any limitations to this enhancement?"

[Ding! The stronger the sword master's body is, the more ghost power will be consumed when using Feedback to improve it! ]

Lin Fan also understood.

This means that it becomes more difficult to improve as time goes by, but overall it is not a big problem.

And the outside world.

After a brief period of adjustment, Tanjiro sheathed his sword and bent down to pick up the cloth bag that had fallen to the ground.

After opening it, I found that it was full of various hairpins.

Think of those girls who were taken away.

Tanjiro already had some vague guesses in his mind, and was even certain that all the girls had been killed.

But being kind-hearted, he turned around and walked up to He Mi, who had already been stunned, and handed the cloth bag to him with both hands.

"I'm leaving now. Please accept this. Maybe one day you can meet that lady again."

He Mi's eyes welled up with tears when he saw this. He took the cloth bag with trembling hands, and after opening it, what caught his eye was the bow hairpin that was so familiar to him.

He now understood the meaning of Tanjiro's words, but in the end he did not tell the truth directly, so he still had hope in his heart.

His eyes were blurred by tears, and he could only sob and shout towards Tanjiro's back.

"Thank you... Thank you so much... I also believe that there will be such a day..."

Hearing this, Tanjiro just turned around and waved his hand with a smile.

"I'll leave that woman in your care."

With that, he turned and walked away along the street, only to find that the street was deserted.

Tanjiro's brows were furrowed, and an unknown fire was burning in his heart after seeing these tragedies.

Hatred towards the root cause of all this, Muzan Kibutsuji!

Lin Fan, who was holding the knife, heard the system prompt sound in his mind.

[Ding! Tanjiro's negative emotions are detected, gaining 20 emotion points! ]

……

Lin Fan looked at his clear point balance, and knew he could unlock a new ability soon if he saved up a little more. He immediately thought about which ability would be the most cost-effective to unlock.

As for the outside world.

The sun rose, and a crow circled in the air and finally landed on Tanjiro's shoulder. After stabilizing its body, it opened its mouth and said.

"The next destination is Asakusa in Tokyo. There are rumors that ghosts are lurking there. Please go there immediately!"

Tanjiro broke out in a sweat after hearing this.

"Hey, are we going to start a new mission now?"

The tight time frame caught him off guard.

But he still resolutely rushed to Asakusa, Tokyo.

After arriving at the mission location.

The sky darkened again. Tanjiro stood on the busy street with the drowsy Nezuko beside him, their eyes wide open, looking a little at a loss.

Are towns and cities like this now?

Lin Fan, holding a knife, looked at the town and couldn't help but sigh.

If I remember correctly, we are now in the Taisho period, which seems to be around the time of World War I, and considerable technology has been developed.

As for this town, there is a sense of transition between the old and the new.

But now that I'm here, I will meet Muzan soon. What should I say then?

Walking on this busy street, Tanjiro was like Granny Liu entering the Grand View Garden, and found everything he saw curious.

Perhaps he was not used to it, so he put on his hood and quickly left the town with his sister. They came to the outskirts of the town, where a street lamp was on in the dark street.

There was a food cart parked under the street light. The bald boss was sitting behind the cart, taking a puff of his pipe from time to time.

Seeing this, Tanjiro hurriedly pulled his sister forward and said listlessly, "Boss, please give me a serving of yam juice udon."

The bald boss responded quickly.

"okay."

Not long after.

Tanjiro sat on a wooden bench outside the car, took the noodle soup handed to him by the boss, and took a sip of the soup immediately.

Then he let out a long breath, but that was when it happened.

A smell that he could never forget suddenly entered his nostrils. In an instant, Tanjiro's expression changed and he stood up.

Even the soup noodles in his hand fell to the ground and shattered into pieces. He couldn't help but gasp for breath.

He quickly ran towards the direction where the smell came from.

This smell...why did it suddenly appear in a place like this?

This is the taste of home at that time.

Walk through the deep alleys, come to the bustling streets, and shuttle among the crowds.

The smell became stronger and stronger.

Kibutsuji Muzan...

In the crowd, he saw a man with his back to him, wearing a black suit and a black and white hat.

He was the source of the smell...

Before he could think about it, a hand had already reached out and pressed on the man's shoulder.

Seeing this, Lin Fan, who had been waiting for a long time, immediately exerted body control and briefly seized control of Tanjiro's body.

Tanjiro did not lose consciousness, but was in a state of watching.

In this state, he can still communicate.

I just heard him ask hurriedly.

"Ajuramaru, what's wrong with me?"

Lin Fan has also entered the state at this moment.

"If you're not careful with this guy, you'll die. Leave the rest to me!"

Back to the outside world.

The man had turned his face to the side, revealing his iconic gem-like cherry-red pupils from under his furrowed brows.

It is certain that this is Muzan Kibutsuji himself!

Lin Fan slowly withdrew his hand and took off his hood expressionlessly.

The two sides looked at each other for a moment.

But it's the next moment.

Suddenly a childish voice sounded.

"Dad, who is he?"

When Muzan turned around, he could see that it was a little girl with twin ponytails, and Muzan was gently comforting his daughter in his arms.

Then he turned around and smiled gently.

"What do you want from me?"

Lin Fan, who had been prepared for this moment, immediately got into the state, showing a cold expression that kept strangers away, and spoke in a deep voice with a hint of anger.

"What's so fun about playing with human emotions? Where's the fun in that..."

Hearing this voice that was engraved in his heart, coupled with Tanjiro's scar and the pendant on his earlobe, a figure emerged in Muzan Kibutsuji's mind.

It was like a nightmare, the man who accompanied him throughout his life!

It was at this time.

Lin Fan asked coldly at the end.

"What do you think of human life?! Why don't you remember..."

Upon hearing this, Muzan Kibutsuji's soul was trembling and his body was shaking uncontrollably.

The fear of that man was infinitely magnified in my heart.
