Demon Slayer: Can I add points to my Breathing Technique?

The blade seemed to be wrapped in golden lightning, illuminating the dimly lit dojo in an instant.

Her straight and strong legs seemed to have hidden boosters, propelling her to unleash incredible speed.

It's less of a sword technique.

Rather than describing it as a bolt of lightning that cleaved through the field of vision, dazzling to the extreme.

Breath of Thunder

The First Form: Thunderclap Flash

Unstoppable.

Xia Xi's pupils suddenly contracted, and all the strength in his body converged into one.

【Full focus! 】

The wind is unpredictable.

Water flows with flexibility.

The rock's stability and solidity.

The essence gained from past arduous training surged forth at this moment, almost simultaneously with the system's bright red attack warning.

I barely managed to sidestep it.

The blade grazed the tip of her hair.

Xia Xi felt a chill beside her ear.

If I hadn't dodged that, although it wouldn't have been fatal, I would definitely have had a scar on my face.

Xia Xi suddenly saw the look in the other person's eyes.

It wasn't murderous intent, but rather a heavier, almost burning expectation.

"Mei-sensei, what are you doing?!"

While parrying the opponent's relentless attacks, Xia Xi called out to stop them.

On the contrary, it made the other party even more excited.

Xia Xi even saw a blush rise on the other person's face, a blush that was only seen when they were excited.

"Of course, I'm testing your skills, hahaha! Everyone says you're strong, so naturally you can withstand my attacks!"

"See? You've taken my sword! Very good, quite capable!"

Several more slashes followed.

Xia Xi's defense sparked a great deal of excitement.

The disciples from the nearby martial arts school were so frightened that they took several steps back.

One of the younger children muttered, "The teacher is going crazy again..."

However, Mei Nikaido acted as if she hadn't heard anything.

He kept accelerating the sword in his hand, pressing it down on Xia Xi.

"Besides, aren't you going to practice Thunder Breathing?!"

"The best teaching, of course, is to fight with all your might! How can you fight without bloodshed? How can you become stronger without bloodshed!"

"Yaguruma Nishitaro, is that it! Kid, come on, look at my chest and breathe with me!"

"I, Nikaido, will teach you a lesson in your teeth, hahaha!"

I don't believe you!

How am I supposed to learn this?!

Xia Xi couldn't help but look away from the other person's magnificent chest.

"Be a little tougher! Where's your backbone?!"

"All show and no substance, are you even chopping wood?"

"Not bad, kid, you're quite sturdy!"

The other party didn't seem to be holding back.

After several minutes of sustained high-pressure attacks, Xia Xi's stamina began to decline, and her movements became somewhat distorted.

but……

The progress bar for Thunder Breathing has really increased?!

While parrying, Xia Xi saw that the progress of his breathing technique was increasing at a speed he had never expected.

Since that's the case, you madwoman!

Come on over!

The next second, Xia Xi switched from defense to offense, merging her figure into the storm and transforming into countless sharp blades to slash at her opponent.

"Oh?"

Her one-eyed excitement and amusement remained.

But at this moment, a genuine interest flashed through his mind.

"It's finally starting to look decent..."

"Very well! Let me test your abilities! I'll make sure you're not just a silver spear with a wax head, a mere five-cart Natsutaro!"

"I won't go easy on you like those idiots."

"Don't cry if you lose."

This guy talks so much trash...

This made Xia Xi feel somewhat at ease.

It's like the extreme swearing of orphan players from all over the world in a game.

However, players may simply be stubborn and prone to swearing, without necessarily possessing the corresponding skill.

But women today truly have the right to be arrogant and sharp-tongued.

That's impressive.

The thunder roared and exploded, once again clashing with the raging winds whipped up by Xia Xi.

……

Late at night, on the roof of the dojo.

Nikaido chatted happily with Natsumi, completely unconcerned about whether it would disturb the sleep of the disciples below.

"Don't dwell on that little thing that happened during the day! A man should be more magnanimous!"

She patted Xia Xi on the back cheerfully and tossed him a bottle of liquor.

The mixed-race female swordsman taunted, "Don't try to fool me with the excuse of being underage! Let's drink!"

Xia Xi reluctantly opened the bottle of wine.

The crisp aroma of alcohol mingled with the night breeze and wafted towards me.

"I must say, senior, your teaching method... is truly unique."

Nikaido was naturally able to understand the unspoken meaning behind the other party's words.

She patted the Nichirin sword lying beside her, the scabbard making a soft sound on the tile.

He laughed and said, "What, you can't even handle this little bit of pressure? You still want to kill all the demons and Muzan?"

She raised her finger and gently tapped her right eye, which was covered by a black blindfold.

What should have been a beautiful, sapphire-like eye was now covered by a lifeless eye patch.

And that old scar that even the eye patch couldn't cover.

In the darkness of night, her smile faded slightly.

"Whether I defeat the Twelve Demon Moons or the Demon King, their minions and Blood Demon Arts are far superior to my Nichirin Blade."

"If you can't even handle my enthusiasm, how can you fight them?"

Are red-named monsters and green-named NPCs the same?

Xia Xi took a small sip and probed, "So you really don't have a grudge against Mr. Kazami?"

"Of course not!"

She grinned, her snow-white teeth gleaming coldly in the moonlight.

"That old scholar who could be blown away by a gust of wind? I wouldn't say I dislike him, but I just think his teaching methods are too outdated."

"Teaching a breathing technique is like starting from the history of the Warring States period."

"By the time you finish this theory, even ghosts will have grown old and died!"

"Although it can lay a solid foundation, how many years can a Demon Slayer Corps swordsman live? Rather than letting a somewhat talented brat like you die in the foundation-building stage, I'd rather let me train more."

"After fighting a lot, you will naturally learn the Breathing Technique of Thunder."

He was drinking heartily while spewing vulgarities.

He's a straightforward guy.

Xia Xi couldn't help but think.

Chapter 31 New Breathing Technique

However, Xia Xi did not expect that this sharp-tongued woman, after her scathing critique of Kazami Kōki, seemed to still not have enough to say.

The conversation then turned to the other trainers, who continued to offer their comments.

"Matsuyama?"
