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

The giant flaming dragon burning from bottom to top and the two huge wind blades slashing down from top to bottom collided in mid-air!

The giant dragon roared, and at the same time as its body was cut off by one of the wind blades, its head also tore apart another wind blade along with the blade!

The blades of both sides also collided at this moment.

next moment.

Fushigawa Miya witnessed with his own eyes that the blade of the Nichirin Sword in his hand was easily cut in half by Ajuramaru.

The broken blade flew out and fell directly on the ground.

The two people passed each other.

After Fushigi Miyabi landed on the ground, he nodded slightly and looked at the broken Nichirin Sword in his hand, his ferocious eyes stunned for a moment.

He really didn't expect that Ajuuramaru could be so sharp!

On the other hand, Tanjiro, who also landed behind him, was rapidly losing his demonic features and was gasping for breath.

But he still turned around with difficulty, bowed quickly and said apologetically, "I'm really sorry for cutting off your Sun Blade, Mr. Shimi..."

The words have not yet fallen.

Fushigawa Miyabi turned around first, looked at Tanjiro with a fierce look and a stern expression, and interrupted him in a cold voice.

"No need to apologize. Your strength has been recognized by me. Let's stop here for today's training."

Having said that, he turned away indifferently.

Tanjiro hurriedly stepped forward and reminded him.

"Let me heal your knife wound first, otherwise it will get worse!"

After saying that, without giving Fushigi Miyabi a chance to refuse, he immediately put his hand on his shoulder, and then thought to himself.

"Please, Ajuramaru."

Upon hearing this, Ajuramaru in the sword immediately released his ghost power to repair the sword wounds on his body, and at the same time used his ghost power to replenish his lost blood.

Feeling the changes in his body, Fushigi Miyabi once again felt the power of Ajuramaru.

This also strengthened his determination!

But he didn't say anything, not even a thank you, but just picked up the broken blade on the ground.

He left without saying a word, leaving Tanjiro with a lonely back. He walked alone on the country road and headed straight for the lord's courtyard.

……

Behind him, Tanjiro looked at his departing back and still felt guilty from the bottom of his heart. Fortunately, he only felt guilty for a moment before he was awakened by Zenitsu who had woken up not far away.

"Hey... my stomach feels like it's going to explode... that guy is relying on his status as a pillar to bully others, isn't he? That's too bad... I'm going to die..."

Zenitsu rolled on the ground like a devil.

Tanjiro, who was not far away, came to his senses and saw the situation, and hurriedly trotted over to him, came to his side and asked with concern.

"Zenitsu, are you okay?"

Faced with Tanjiro's concern, Zenitsu's expression became even more painful, and he begged with trembling body.

"How can I be fine? My ribs seem to be broken...Hurry up and ask Ajuramaru to heal me..."

This doesn't seem like a pretense, after all, Fushigi Miyabi didn't hold back when he threw that punch just now.

Tanjiro squatted down helplessly, put a hand on Zenitsu's shoulder, and then said in his heart, "Sorry to bother you, Ajuramaru, please heal Zenitsu's injuries as well."

"Okay, it's up to you."

Ajuramaru reluctantly released his ghost power, and the black thread followed Tanjiro's arm and touched Zenitsu's shoulder. The ghost power then entered his body and repaired his injuries.

But Zenitsu was there with a red face, looking like he was enjoying himself, as if he was in ecstasy, "Hehe...Ajuramaru is healing my injuries..."

Seeing this perverted look, Tanjiro's mouth couldn't help twitching. He really wanted to tell Zenitsu the truth, but he was afraid that he couldn't accept this blow.

So now he is extremely conflicted.

Only after his injury was completely healed did Tanjiro withdrew his hand, looking a little worried.

But in the end he didn't say anything, instead he ran to Inosuke and treated his injuries as well.

Although Inosuke looked like he was beaten badly, he only had superficial injuries, which were obviously caused by Fuzugawa Miyamoto.

Tanjiro, who saw all this, couldn't help but give his own evaluation, "Mr. Shima is indeed a gentle person..."

Hearing this, Zenitsu raised his voice in a devilish tone, "Ah?! That guy is so gentle? He broke my ribs!"

Inosuke beside him looked at Zenitsu with disdain and mercilessly attacked him in his hoarse voice, "You are such an annoying guy!"

"Who are you calling annoying?!"

Shan Yi immediately retorted.

And Tanjiro could only try to stop the fight.

"Stop arguing, let's continue training together. I also want to learn your Lightning Breathing from Zenitsu..."

"Hmph! First learn my beast breathing..."

The three of them continued to concentrate on their breathing on this plain. In addition, Tanjiro also began to practice Kagura, the God of Fire.

……

at the same time.

Fushigawa Miya came to the mansion alone, entered the room, found his lord, knelt on one knee and reported respectfully.

"My lord, after Tanjiro Kamado transformed himself into a demon, he has the strength to rival mine, but his fighting skills are still too immature. However, his absolute strength is enough to make up for this.

If he unleashes the power of Aguramaru, perhaps even I won't be his opponent!"

He reported all his views truthfully.

On the other hand, after hearing this information, Ubuyashiki Yoya's mouth corners slightly raised and he looked over with a kind look.

"Thank you for your hard work, Shiya.

If Tanjiro has the ability to defeat you, then I can let him leave the headquarters and go out on a mission without worry."

After all, after understanding Aguramaru's abilities, Ubuyashiki Yoya knew that he could make him stronger quickly.

There is only fighting and killing evil spirits!

Now that his strength has been recognized by Shimi, we can let him leave the headquarters without worry. There are more and more evil ghosts now.

These evil spirits will become nutrients for Tanjiro to become stronger!

Muzan Kibutsuji, you are ready to die!

……

at the same time.

In the intricate infinite city, there are countless buildings and houses combined, which even goes against the common sense of physics and is located on a wooden platform in the center.

A handsome young man with neck-length black hair and a sickly flushed face was kneeling on the ground, with numbers engraved on his deep blue eyes.

It also explains its identity.

It is the current Lower Moon One, Nightmare!

On another platform opposite him, Muzan Kibutsuji was looking at him with his extremely indifferent peach-pink eyes.
