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

As he spoke, murderous intent was evident!

"Why are the Lower Moon Demons so weak? Becoming one of the Twelve Demon Moons is just the beginning. It's the beginning of becoming stronger and being able to be used by me!

The upper demons have never been replaced in the past hundred years, but what about the lower demons? This time, the ghost hunter killed five of them in one go!"

Speaking of this, Muzan even gritted his teeth, and there was an imperceptible fear in the depths of his eyes!

"Now I think that the Twelve Demon Moons only need the Upper Moon. Do you have anything else to say before you die?"

There is no room for negotiation.

All it does is make you wail and cry before you die!

But it just so happens that Nightmare itself is an out-and-out pervert, and it still has no fear in the face of the threat of death.

His expression even flushed morbidly, he raised his hands slightly, his eyes full of admiration and satisfaction!

"Yes, I feel like I'm in a dream right now. I'm so happy that you can end my life in person..."

This perverted look successfully aroused Muzan's interest, and there was even a smile on the corner of his mouth.

Then he controlled the extended flesh and blood tentacles and stretched them out quickly. The sharp spikes on the top pierced directly into Nightmare's neck.

Then blood is transported inside.

The moment the tentacles were retracted, Nightmare fell to the ground, his body twitching uncontrollably, veins bulging on his face.

It seems like he is suffering from some inhuman torture.

And Muzan was there, enjoying Nightmare's pain with interest, and then he slowly spoke.

"I've taken a fancy to you, so I'll give you more blood this time. However, you may not be able to bear it and die. But if you adapt, you will become even stronger!"

He paused, then pointed his finger at his ear and continued.

"Go kill the demon hunter with the Hanafuda earrings on his ears. If you kill him, I will give you more blood!"

The words fell.

The sound of a pipa came from behind.

The fallen Nightmare was also teleported out of the changing Infinite City and landed on an empty street at night.

Nightmare lay here, feeling the memories transmitted in the blood, which were Tanjiro and the various information he had collected.

I saw him smiling with a painful look on his face.

"It's like a dream to get your approval to kill this ghost hunter..."

And in the infinite city.

Muzan once again summoned the Upper Moons among the Twelve Demon Moons!

You have to know that the ghost hunter who is suspected to be possessed by the ghost of Yuichi Tsugakuin cannot be killed by Nightmare, so he was given blood.

It's just one of many baits. If you really want to kill that monster, you have to at least string it up!

But if the Upper Ranks can’t do it, then it will give up on attacking Tanjiro.

As for what to do with the dead upper moon?

If the strings of a musical instrument break, don't you just need to replace them? As long as the owner of the instrument still exists, that's enough!

……

And the other side.

Demon Slayer Headquarters.

Butterfly House.

At this moment, after fighting with Fuzukawa Miyabi, Tanjiro and the other two returned here and continued training in the courtyard.

But in my spare time.

Tanjiro was sitting in the corridor, eating a rice ball, with three girls kneeling beside him. One of the girls asked in a crisp voice.

"Um... Mr. Tanjiro, are you currently practicing full concentration breathing 24 hours a day?"

The three little ones were watching curiously.

Tanjiro also glanced at the Aguramaru on his waist, turned around and faced the three people with a gentle smile, "Thanks to the Aguramaru, I can now keep breathing with full concentration."

"Amazing……"

When the three little ones looked at Ajuramaru, their faces were full of curiosity.

One of them even asked.

"Then Mr. Tanjiro, would you like to try blowing the gourd?" As he said this, he took out a small gourd and placed it directly on the corridor in front of him.

Tanjiro took a bite of the rice ball in his hand and asked with a smile on his face.

"Do you want to blow the gourd to make a sound?"

"No, we need to blow the gourd to pieces." The girl's voice was clear and pleasant, but her words were a bit scary.

"Blow it up?"

Tanjiro took the gourd and knocked it, making a bang bang sound. It was obviously not ordinary hard.

"That's right, the gourd that Ms. Kanao can blow up now is a bigger gourd." As they said that, the three little ones moved the gourd out.

It was so big that it was almost as tall as me!

"Would you like to try it?"

The three little ones are still asking.

Tanjiro felt a little scared when he thought that such a slender girl could actually blow up the gourd.

Just when he was thinking about whether to give it a try.

Ajuramaru's voice rang out in his mind.

"This gourd is not difficult for you. You have already mastered it perfectly in the whole collection. Now what you need to do is to hone your fighting skills and master the Fire God Kagura.

In addition, you need to learn more breathing methods and combine them together!"

Hearing this, Tanjiro also understood Ajuromaru's good intentions and answered very seriously, "Thank you Ajuromaru for your guidance, I will definitely work harder!"

As he said that, he stood up, walked towards the big gourd in front of the three little ones, and asked.

"Can I try it?"

"of course can."

The three little ones said in unison.

Zenitsu and Inosuke, who were exercising madly not far away, heard the sound, stopped exercising and looked over curiously.

Then the two of them saw that Tanjiro actually blew up the huge gourd, and the gourd fragments flew everywhere.

Amidst Tanjiro's apology.

The two fell silent.

"This is not good, it seems like we are being completely left behind!" Zenitsu widened his eyes. Although he knew this would happen, he was still unwilling to accept it.

In contrast, Inosuke was very straightforward, "Humph! I can do it without the help of that knife!"

As he said that, he began to train frantically.

Even Zenitsu had to temporarily abandon his lazy personality and focus on training.

Time just flies by so quickly.

The next morning.

The three of them were still the same, having just gotten up.

In the room, a man wearing a red cloak and looking righteous appeared, the Flame Pillar Rengoku Kyojuro!

"Young men, come with me for training. I will train you with all my strength. Now follow me!"

Tanjiro sniffed and could sense the man's strong sense of justice from the scent he emanated from.

He is undoubtedly a good person!

"Ok!"

Tanjiro and Inosuke showed no resistance, but Zenitsu rolled over on the bed and cried, "I don't want to be beaten again...ah...Yamete..."
