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

Lin Fan in the knife had already disconnected and was listening attentively to the prompt sound of the system in his mind.

[Ding! It was detected that the Lower Moon Four Zero Yuzi had strong negative emotions before his death, and 3000 emotion points were obtained!

The disease of the Lower Three was detected, and the person had intense negative emotions before dying, gaining 3200 points of emotion value!

The second winder of the lower moon is detected, which occurs before death... Gain 3700 emotion points!

Ding! Demon King Muzan Kibutsuji is detected to have intense negative emotions, gaining 5000 emotion points! 】

A total of 7000 ghost powers were obtained, and % of the ghost power was given back to the sword master Tanjiro Kamado! 】

The system prompt sounded.

Lin Fan's delicate mouth corners couldn't help but rise up.

Wuzan, you are indeed my true love!

Not only rewards, it also gives gifts.

It just makes me cry...

……

at the same time.

In the Infinite Castle, Muzan is on the verge of collapse.

"These lower-ranked ones are useless, they are useless!... And what on earth is that thing on that guy... Why can't he be killed? Is he really possessed by a ghost?"

And the sword skills he used!

It will never forget it no matter what, it can confirm it with just one glance.

This is the Breathing of the Sun used by Yoriichi Tsugikuni!

But everyone who knew about it has been killed, so how could this guy know it...

Everything connected together points to one answer, that is, Yuichiro Tsugikoku turned into an evil ghost and came back possessed by this young man!

Come back and kill it!

Thinking of this answer, Muzan covered his face with one hand to block his extremely frightened eyes and his whole body trembled slightly.

The hidden scar on its body was also aching slightly, and now it had only one thought in its mind.

It will never leave this Infinite City again!

……

Natian Spider Mountain.

Among the people who came.

One of them, a woman with a butterfly hair accessory and a butterfly dress, had a nimble figure and light steps. She tiptoed and came to the unconscious Tanjiro first.

The person who came was actually the Insect Pillar, Shinobu Kocho.

I saw him leaning forward slightly, with a smile on his face all the time.

"Is this the young man that my lord was talking about? Are you okay?" As he said this, he began to observe Tanjiro's condition. After all, Ubuyashiki Yoya had already specifically reminded him before.

But after taking a look, I found that there was nothing wrong with my body, so I felt relieved.

The Flame Pillar Rengoku Kyojuro, who had long golden-red hair, also came over. His cloak fluttered in the wind, and his scarlet-gold eyes immediately looked at the ground.

At this moment, the Nichirin Sword in Tanjiro's hand had been completely corroded by the venom that burst out when the sick monster died.

The blade looks incomplete and obviously destroyed. When looking at Tanjiro's waist, you can find another blade!

"The Sun Blade is broken! But it seems that the other one is the special Sun Blade that the lord mentioned!"

The voice just fell.

Next to him appeared a muscular man named Yusui Tengen, with white hair tied up and two swords on his back. He was also examining the swords.

Although he could only see the hilt and scabbard, he still gave it a very high evaluation, "This is really a gorgeous Sun Wheel Sword."

Compared to the two people who were watching, the Wind Pillar, Mushiko Fushigi, who also had white hair and scars all over his body, walked forward without any hesitation.

During this time he suppressed his anger.

"I really don't know why this guy has such high hopes from the lord. He is even more important than the lord. I really can't understand it!

Anyone with a ghost should die!"

With an angry kick, he turned Tanjiro over while he was lying on the ground. Then he looked at the Sun Blade at his waist with a fierce look in his eyes.

He immediately reached out to grab the handle of the knife, trying to snatch it away.

The next moment.

The handle of the knife emits a pitch-black smoke that forms a sharp spike. If you grab it, your palm will surely be pierced through.

Fortunately, Fushigi Shimo noticed something was wrong and withdrew his hand in time, but his eyes were cautious when he looked at Ajuramaru.

"Is this the sword that can turn the tide? It's really extraordinary..."

As he spoke, he glanced towards the box not far away, murderous intent in his eyes.

Fortunately, the current Water Pillar, Giyu Tomioka, stepped forward in time and stood in front of the wooden box without changing his expression. He was not good at speaking, so he spoke directly through his actions.

There was nothing Fushigawa Miyabi could do. After all, his lord had already explained it in advance, and he would tell them the truth when he returned.

And they have all witnessed Tanjiro's performance.

According to the intelligence, there are four Lower Moons of the Twelve Demon Moons here. Although it is nothing to them, Tanjiro can defeat these Lower Moons.

This was something they had never thought of.

It was Shinobu Kocho who stood up and suggested with a smile, "Let's take the people back first. The lord is still waiting for us."

After saying this, he turned his gaze to Zenitsu and Inosuke over there, "Then please come with us, both of you."

"Who are you?!"

Inosuke stepped forward, holding two swords in his hands and questioning in his unique voice.

Zenitsu beside him couldn't help but start to make fun of them. These guys looked terrifyingly strong just from their standing postures...

But they all seem to be members of the Demon Slayer Corps...

Thinking of this, he quickly reminded in a low voice.

"Inosuke, they all seem to be from the Demon Slayer Corps, why don't we just follow them..."

"Humph!"

Inosuke snorted coldly when he heard this, but did not say anything in rebuttal.

On the other hand, Insect Pillar Shinobu Kocho always had a smile on her face as she called over two hidden members.

Two people came here wearing black combat uniforms and hoods covering their heads and faces.

Kocho Shinobu reminded with a smile.

"Take this boy with you. Pay attention to the knife. Be careful not to touch it to avoid getting hurt."

The two Hidden Ones were a little confused, but one of them still walked forward, grabbed Tanjiro's arm and put it on his back.

During this period, no reaction was caused by Ajuramaru.

When Fushigi Miyabi saw this, his expression changed slightly.

"As long as you don't touch the knife directly, you won't be attacked..."

"It seems so."

Shinobu Kocho replied with a smile, but if you look at this smile for a long time you will find that it is unchanging and looks very fake.

"No one except that young man can touch it? This is a gorgeous sword..." Uzui Tengen put one hand on his forehead, and a different look flashed in his eyes.

However, Rengoku Kyojuro's thoughts were much simpler. He looked at everyone present with a determined gaze, and then spoke righteously.

"Let's finish the work here as soon as possible. Our lord is still waiting for us!"

Say it.

Everyone came back to their senses from the knife and dispersed to clean up the surviving ghosts in Spider Mountain and treat the wounded.
