Achievements of the Strongest Demon Blade from Demon Slayer!

This was simply too terrifying!

Lin Fan had barely had any free time that entire night. Not to mention Tanjiro, even just slapping him had consumed quite a bit of demon power.

He had also needed to expend additional demon power to help Tanjiro heal.

Otherwise, by the next morning,

Tanjiro's face would have been swollen bigger than Inosuke's boar mask.

The next morning.

Tanjiro got up with dark circles under his eyes, and the first thing he did was practice his Breathing Style.

From sunrise to sunset.

He continuously tempered himself, and his body gradually began to transform. This was not the direct improvement of feedback, but another kind of reward unique to training.

The most noticeable change was his rapidly increasing stamina.

Zenitsu and the others still watched Tanjiro train from the corridor, with no motivation whatsoever to join him.

However, while Tanjiro trained,

Lin Fan deliberately reminded him,

"A person does not necessarily have to master only one Breathing Style. You can learn several Breathing Styles and use them together, or even fuse them.

That guy named Zenitsu has a pretty good Thunder Breathing. You can try asking him about it."

"I see."

Tanjiro pondered as he trained. Then he set down the boulder on his back and jogged over to Zenitsu in the corridor.

He bowed slightly.

"Zenitsu, could you teach me Thunder Breathing?"

"Huh?"

Zenitsu was a little dumbfounded, his expression somewhat stiff.

He did not speak for a long time.

It was not that he did not want to teach him. The main problem was that he only knew one move himself!

But looking at Tanjiro before him, he still relented. "Well... it's not impossible, but let's make this clear first. I only know the First Form of Thunder Breathing. I can't teach you anything else."

"Really? Thank you so much, Zenitsu."

Tanjiro did not care about what came after at all. He immediately stepped forward and thanked him with a smile.

Inosuke followed up as well.

"Why aren't you learning Beast Breathing from me?! My Beast Breathing is the strongest!"

Tanjiro merely smiled before talking with Zenitsu first.

Sitting in the corridor, Zenitsu recalled his past training in Thunder Breathing and thought of that old man.

"Tanjiro, when using Thunder Breathing, you need to focus your awareness on your feet. Things like body shape and muscle size cannot truly be controlled with precision.

Only once you understand that will you have truly mastered Thunder Breathing. That's what my grandpa, who raised me, always told me."

Tanjiro did not completely understand, but he still studied earnestly.

After all, learning a Breathing Style was not something that could be mastered overnight. Back when he had learned Water Breathing, it had taken him several years.

In the blink of an eye, three days passed.

Tanjiro could now maintain Total Concentration Breathing for increasingly longer periods, which directly caused his basic stamina to soar.

Perhaps they had been moved by Tanjiro.

Though reluctant, Zenitsu and Inosuke occasionally trained with him for a while.

The days passed peacefully like this.

But Lin Fan knew Muzan would not simply let this go. There were likely demons searching the surrounding area for them every day.

These days of peace probably would not last much longer.

A storm was brewing.

This was merely the final calm before the storm.

Lin Fan saw it clearly.

And just as Lin Fan had expected, after the sun set on the fifth day,

Night fell!

Will You Win?

Tanjiro and the other two were resting in their room when suddenly,

Lin Fan, inside the blade, sensed something and immediately warned him, "Tanjiro, a demon is rapidly approaching!"

Hearing that, Tanjiro, who had been yawning and preparing to sleep, abruptly stood up. He changed into his Corps uniform and strapped his twin blades to his body.

He spoke to Zenitsu and Inosuke beside him.

"A demon is heading our way!"

The moment he finished speaking,

Zenitsu reverted to his usual self and immediately began trembling convulsively.

"Huh? Why does this never end? Tanjiro, what exactly did you do? Why are demons always chasing after you...?"

Neither of them paid any attention to Zenitsu's resentful complaints.

Inosuke also drew his twin blades and asked, "How many demons came this time? I'm definitely killing more than you!"

"Just one."

Tanjiro answered over his shoulder, then pushed open the door and was the first to enter the courtyard, standing ready for battle.

Zenitsu was no longer quite so afraid.

"Only one demon? If Tanjiro's here, then there's nothing to worry about."

Not long after.

In the pitch-black night, a figure slowly floated down from the air into the courtyard beneath the moonlight. At first glance, it spotted Tanjiro in the distance.

When it looked closely and saw the hanafuda earrings and the twin blades at his waist, it immediately confirmed that this was the brat that person had specifically ordered killed!

Tanjiro also drew Ashura Maru from his waist. Looking at the demon before him, the stench and bloody smell rolling off it assaulted his nose.

It was hard to imagine how many people it had eaten, or how terrifyingly strong it must be.

When his gaze settled on the demon,

he saw that it was roughly the same build as himself, except it had black hair, especially the four braids tied like red maple leaves.

Aside from that, it wore a yellow-and-white kimono, and its pale face bore a dark green I-shaped marking.

But none of that was important.

What mattered were the words inscribed in its light purple eyes.

Lower Six!

Tanjiro had now confirmed the identity of the newcomer. It was the current Lower Rank Six among the Twelve Kizuki!

The demon licked its lips and gave a bloodthirsty smile.

"I am Lower Rank Six, Kamanue.

By that person's command, I have come to take your head back. You can die now!"

"I refuse!"

Tanjiro answered resolutely without a second thought.

At those words, veins bulged on Kamanue's forehead.

"I wasn't asking for your opinion! You selfish, vile human, I sentence you to death!"

With that,

its limbs mutated, turning into broad, patterned claws.

At a glance, they resembled a tiger's limbs.

Appearing so abruptly on a human body, they looked extremely unnatural.

Lin Fan saw this scene from within the blade.

If he remembered correctly, this demon was supposed to be killed by Muzan in Infinity Castle in the original story. He had not expected it to be sent early to kill Tanjiro.

As Lower Rank Six, it should not be weak. Judging by this, its Blood Demon Art was likely some sort of transformation ability...

Lin Fan analyzed the situation rapidly.

At the same time, he released demon power to strengthen Tanjiro.

Tanjiro had already gripped his blade with both hands and launched the first attack, exerting force through his feet as he rushed forward.

Behind him, Inosuke had also emerged with his twin blades in hand, his eyes beneath the mask filled with fighting spirit.

"Ha ha ha ha... I'll chop it to pieces!"

With that, he leaped forward as well, closely following behind Tanjiro.

Faced with the two charging at it, Kamanue could no longer suppress its desire to slaughter. It also exerted force and chose to confront them head-on.

As it closed in, it raised a tiger claw and swiped forward. Its claws tore through the air with a piercing whistle.

Facing this attack, Tanjiro calmly swung his blade. Seeing this, Kamanue's eyes filled with ridicule and mockery.

After all, its tiger claws were harder than steel!

But in the next instant,

its confidence was ruthlessly shattered.

The blade cut through the skin of its tiger claw like slicing tofu and drove deeper inside.

"How is that possible?!"

Kamanue had no time to think. It immediately pulled back with all its strength, violently retracting its arm as its body retreated rapidly.

Only then did it avoid having its tiger claw severed in a single strike. Even so, the claw had been sliced halfway through horizontally, the wound a horrifying sight.

It knew that wounds inflicted by this blade could not regenerate.

But it had never expected

the blade to be so sharp. If it had reacted any slower, its hand might have been cut off just now.

"You dare wound me? Your sins are unforgivable!"

Kamanue roared coldly.

Inosuke suddenly appeared at its side and swung his twin blades with all his strength at its neck. "Ha ha ha ha! Become a stepping stone on my path to becoming stronger!"

Tanjiro also launched a surprise attack from the front.

Faced with the two's seamless coordination,

Kamanue raised its right arm to shield its neck. After the twin blades struck it, they did not even break the skin, producing only the clang of metal on metal.

"Get lost!"

With a powerful swing of its arm, it knocked away both the blades embedded in its body and Inosuke along with them.

But it was given no time to catch its breath.

Tanjiro had already closed in.
