Explosive Blade Formula from the Demon Slayer World!

[Boom boom boom]

A series of thunderous Sound Explosion, accompanied by one massive explosion after another, ravaged the Ubuyashiki Estate. The deafening noise and the oncoming Huoguang made it quite uncomfortable for the onlookers in the distance.

Especially the two girls, one big and one small, Mitsuri Kanroji (the Love Hashira) and Mumei, covered their ears tightly.

"This fight is so loud! It's incredibly noisy!"

Mumei began to complain, but in such a noisy environment, it was difficult for anyone other than those around her to hear her.

"This is Mr. Uzui's Sound Breathing. We can only endure it. I wonder how long he can hold out against Mr. Mitsui."

Love Hashira Mitsuri Kanroji shouted loudly into Mumei's ear.

This was the third day that Mumei and Laskey had been at the Demon Slayer Corps Headquarters.

That day, after Laskey decisively defeated the Wind Hashira Sanemi Shinazugawa with his "Wind Breathing" sword technique, he went on to defeat the Water Hashira Giyu Tomioka and the Serpent Hashira Iguro Obanai, and also performed a "fight fire with fire" act on the spot.

This dealt a heavy blow to everyone's worldview, even Sakonji Urokodaki.

From then on, no one questioned the claim that 'Mr. Mitsui's' talent was comparable to Yoriichi Tsugikuni's. At the same time, he received the highest level of welcome from the Demon Slayer Corps, and a lively banquet was held that very night.

As mentioned before, the Demon Slayer Corps' greatest significance is to kill demons, Muzan.

Previously, due to their limited combat strength, these Pillars could easily deal with demons of the 'Lower Rank' level or lower. However, if they encountered an 'Upper Rank' on their own, they would most likely become prey for the demon.

Over the past few centuries, far too many Pillars have died at the hands of the Upper Rank.

The appearance of this 'Mr. Mitsui' gave everyone, including Kagaya Ubuyashiki, a glimpse of the possibility of eliminating the 'Upper Rank'.

What a joyful thing this is!

Even Sanemi Shinazugawa, the Wind Hashira who was taught a lesson by Laskey to the point of vomiting blood, actually welcomed the former's joining, but on the surface he would definitely put on a sour face.

However, Laskey's curiosity was not satisfied by just three pillars, so he proposed that he wanted to continue to spar with the other six pillars.

No one disagreed with this.

Firstly, through the three battles on the first day, these pillars have discovered that 'Mr. Mitsui's' personality is not actually that bad.

Although Giyu Tomioka and Iguro Obanai were also defeated by their opponent, they only suffered minor injuries and the fight ended there. This proves that Sanemi Shinazugawa received special treatment solely because of his foul mouth and bad attitude.

Secondly, swordsmen have a strong competitive spirit. Even if they feel they can't win, they still want to experience the feeling of fighting against a strong opponent and see if the other party can Imitation Magic their Breathing Technique.

In this way.

The next day, which was yesterday, Laskey fought against the Insect Hashira Shinobu Kocho, the Love Hashira Mitsuri Kanroji, and the Mist Hashira Muichiro Tokito.

The outcome of the match is self-evident; his focus was mainly on certain characteristics of these three individuals.

Shinobu Kocho, the Insect Hashira, is physically weak, but her thrusting speed is extremely fast, and her technique is somewhat similar to the Shigan technique in the Rokushiki.

Furthermore, the elusive movements of the Mist Hashira, Muichiro Tokito, are as elusive as a thin mist, much like the Paper Arts in the Rokushiki, except that he has an additional layer of mist effects to conceal it.

Then there's the Love Hashira, Mitsuri Kanroji, a beautiful girl with pink braids that have green ends. Although she's less than 1.7 meters tall, she possesses a powerful strength that seems completely out of place with her petite frame.

What surprised Laskey most was that when she tensed her muscles, she could greatly increase her body's rigidity, making it easy for her to withstand blade attacks.

What's this?

Tekkai!

It was only through conversation that I learned that this Love Hashira had a special physique; her muscle density was eight times that of an average person in this world, which also allowed her to eat more in one meal than the combined amount of three sumo wrestlers.

Laskey didn't know the muscle density of ordinary people in this world, but through specific sparring, he could feel that his opponent's physique had reached the level of the Sea Star Person, and was even much stronger than most ordinary people. After all, even in the Sea Star Homeworld, not many people could train to become 'Tekkai'.

As for the issue of food intake, it's because ordinary food doesn't have enough nutritional content, and there aren't any other highly nutritious ingredients in the world.

This made him realize that this girl had truly been born in the wrong world.

And now, on the third day.

Laskey's opponent is the Sound Hashira, Tengen Uzui, and the Breathing Technique and Swordsmanship he is currently using are the same as his opponent's 'Sound Breathing'.

"Fourth Form: Constant Resounding Slashes!"

"Fourth Form: Constant Resounding Slashes!"

One wielded an ordinary Samurai sword, while the other used Black-Gold Twin Blades linked by a chain. They simultaneously unleashed the same sword techniques. Although their movements Taiyi, the high-speed afterimages of the swords, almost invisible, and the thunderous roar were identical.

The characteristic of this so-called 'Sound Breathing' is that the sword speed is fast and the sound is loud.

Strangely, Laskey's attacks did not produce any explosions or Huoguang, while Tengen Uzui's twin swords always produced violent explosions every time they clashed.

And it wasn't some special effect; it was a real explosion with high temperature and blast wave!

It was his knife.

In the midst of a fast-paced, intense battle, Laskey Hardening his Samurai with Armament Haki while narrowing his sharp eyes to examine the chain swords in his opponent's hand—a sword with a black back and a gold blade.

Honestly, anyone else would have been unable to withstand wave after wave of close-range bombardment.

However, with his overall strength far surpassing that of Tengen Uzui, even without the boost from this explosion, his faster and more powerful 'Sound Breathing' alone would be enough to contend with him.

"If this could be mass-produced..."

Unsurprisingly, the bigwigs of the Otherworld Strategy Committee, who witnessed everything through the Den Den Mushi, immediately noticed the value of the knife.

Meanwhile, Laskey also noticed something interesting.

"This guy, who's supposedly a ninja, is actually stronger than that Love Hashira!"

"That's strange. Most people in this world are physically weak, not much different from the people in the Kabane World."

He had realized that the Wind Hashira, Water Hashira, Mist Hashira, and Sakonji Urokodaki were the average level of people in this world after strengthening their physique through Breathing Technique.

People with special constitutions include the Insect Hashira, who has extremely weak wrist strength; the Serpent Hashira, who can move normally even after three days without food; and the Love Hashira, who has eight times the muscle density of an average person.

Clearly, the Sound Hashira in front of us must also be special.

[Boom!]

Even if he was exceptional, after Laskey thoroughly understood his situation, he directly increased the force and used the most basic form of "Sound Breathing," "First Form: Boom," which was simply a downward slash that sent him flying.

[Swish--]

With a swift leap, he caught the Black-Gold Twin Blades that had been sent flying high into the air. Landing back on the ground, he examined the beautiful blades with interest before looking up at Tengen Uzui, who was clutching his chest as he stood up. He then walked over and returned the twin swords to him.

"A knife that can explode? That's really interesting. Is it even possible to manufacture such a knife?"

Upon receiving the twin swords, Tengen Uzui hesitated for a moment when asked the question. Realizing that others also knew about this, he then proceeded to explain truthfully.

"When manufacturing the Nichirin Blade, as long as I add my specially made Tengu Gunpowder, the blade will have the effect of exploding with just a little friction."

"However, this kind of explosion is tantamount to suicide for others, so I'm the only one in the Demon Slayer Corps who uses it."

Laskey's eyes widened slightly, and Kongming and the others at the command center on the Sea Star Homeworld also brightened up. Chairman Fernandez was all smiles.

"This Tengen Uzui is quite impressive. Not only can he train those Ninja Beasts, but he also possesses such a miraculous gunpowder formula. He's a real talent!"

"Absorb it! It must be absorbed!"
