Flame Pillar: Kyojuro Rengoku!

Water jet: Giyu Tomioka!

Insect Pillar: Shinobu Kocho!

Serpent Pillar: Obanai Iguro!

Wind Pillar: Sanemi Shinazugawa!

Rock Pillar: The Dark Journey of Sorrowful Island!

Demon Slayer Corps Master: Ubuyashiki Kagaya!

And our main character: Chinatsu Kamado!

The group sat in a room, with Chinatsu and Kyojuro in the center, closest to their lord. Even closer to their lord were their swords.

"It really has changed... It's amazing..." The lord looked at the two swords in astonishment and didn't know what to say.

He had previously consulted all the family books, and he trusted his memory; there was absolutely no record of this in the family archives… not even a single one!

What do you think?

After calming down a bit from his initial surprise, the lord raised his head and asked the people in front of him for their thoughts on the changes to the Nichirin Blade.

Although none of the people present understood the forging techniques of Nichirin Blades, they were people who had fought on the brink of death with Nichirin Blades for many years, and naturally had their own thoughts on this change in Nichirin Blades.

“The blade has generated high temperatures due to continuous collisions. The reason why the Nichirin Blade can kill demons is because the ore used to forge the Nichirin Blade contains the power of the sun. But now that the Nichirin Blade is like this... I think it should be even more threatening to demons…” Obanai Iguro, the Serpent Pillar, spoke first.

His senses were very sharp, and he could sense that the Nichirin Blade in front of him was emanating an even stronger aura of "Nichirin Blade" than before.

“I agree with that statement, but let’s conduct an experiment before making a conclusion. For example, let’s kill a ghost with this knife and see the ghost’s reaction.” Shinobu Kocho squinted and held up a finger, offering her opinion.

Everyone around nodded in agreement. This experiment was definitely going to be conducted; without it, all their talk would be just empty words.

The activation of the Crimson Blade is not permanent, because the Crimson Blade is essentially a "Nihonrin Blade under high temperature". It amplifies the solar power within the ore used to forge the Nihonrin Blade through high temperature. Once the high temperature of the blade cools down, the Crimson Blade will be downgraded back to a regular Nihonrin Blade.

After a period of discussion, the experiment on the "Crimson Blade" began in an orderly manner under the Lord's arrangement.

First, the Pillars teamed up in pairs and fought like Chinatsu and Kyojuro, trying to see if they could also make their Nichirin Blades become like Chinatsu and Kyojuro's two through high-frequency clashes of their Nichirin Blades.

After a series of noisy experiments, all the Pillars except Shinobu Kocho successfully activated their Crimson Blades. It was a pity that Shinobu Kocho was unable to complete a high-intensity sword-fighting duel because her strength was too weak.

After confirming that the form of the Crimson Blade was not accidental, they began to experiment with its performance.

In a small alley in a certain county town, a demon is running wildly.

Is he hunting down humans?

No, he's being hunted down by humans!

Behind him, Sanemi Shinazugawa was rushing towards him at breakneck speed, his expression more ferocious and terrifying than that of a demon.

"Wind Breathing - First Form - Dust Whirlwind - Slash!"

Sanemi's figure flashed, like a horizontal hurricane sweeping past. In the blink of an eye, he was in front of the demon from behind. The demon, which had been running and trying to escape, had both arms severed and was in too much pain to run, so it stood still and let out a series of roars.

Under normal circumstances, injuries of this level, even if very painful, would regenerate quickly. However, the demon's arm shows no signs of regeneration whatsoever, a fact that the demon cannot comprehend.

"Why...why! Why can't my arm regenerate! It hurts! It hurts so much! It hurts so much..."

Whoosh!

Sanemi wielded his crimson sword and slashed from bottom to top, and the demon lost its life in excruciating pain, turning into smoke.

Sanemi brandished his crimson sword, a smirk playing on his lips, a fiery glint in his eyes.

………………

Three days later, Sanemi, who had returned from the Crimson Blade experiment, told everyone present that the Crimson Blade could suppress the regeneration of demons. The Pillars and the Lord clenched their fists in joy.

It can suppress the regeneration of demons!

Their initial expectation was that it would only increase the damage, so the fact that it could also suppress the regeneration of the demons was a pleasant surprise.

While everyone was pleasantly surprised, they didn't forget to analyze the weaknesses of the Crimson Blade.

First, the duration was short.

Second, activating it by collision is troublesome. It requires not only cooperation between two people but also time. Facing a powerful demon, it is difficult to have this opportunity to stabilize the Nichirin Blade.

Just as everyone was pondering this, Chika quietly stretched out her arm.

"Hey, how about we all test our grip strength?"

Chika's words made everyone present pause in surprise. Grip strength? Does that mean gripping the knife handle tightly with your hand? Grip strength increases temperature? That's so mystical.

Seeing the puzzled looks on everyone's faces, Chika could only respond with a smile.

Mysticism? You guys are actually criticizing this mysticism? I also think it's mysticism, but that's how the author drew it, what can I do?

If Chinatsu hadn't thought her grip strength might not have met the standard, she would have demonstrated it directly.

In the original work, the Serpent Pillar and the Mist Pillar activated their Crimson Blades through grip strength, while the other Pillars activated them by colliding with each other in pairs.

So, the Mist Pillar and the Serpent Pillar have the greatest grip strength?

Of course not. Moreover, the Serpent Pillar and Mist Pillar had the assistance of "Scarlet Marks" when they activated their Crimson Blades. Their power increased after their lifespans were shortened. At this moment, none of the Pillars present have activated their Scarlet Marks. Can a truly capable person activate a Crimson Blade with just their grip strength? Chinatsu doesn't have that confidence either.

Just as the scene suddenly fell silent, the strongest man in the Demon Slayer Corps stepped forward!

The Island of Lamentation is now in the Dark!

This person is the strongest member of the Demon Slayer Corps today, and Upper Moon One called him "the strongest human body encountered in 300 years." The author has not made the ranking of the Pillars public, so there are many different opinions on this matter, and everyone has their own understanding. Only the Stone Pillar firmly holds the position of the strongest.

"Let me try this method."

Gyomei Himejima stepped out from the group of Pillars with his hands clasped together. No one cared about it; everyone knew that the Stone Pillar had the strongest grip. If the Stone Pillar couldn't activate the Crimson Blade through grip strength, then they couldn't either... at least not at this stage.

As he stepped out of the group, he also took out his "Nichirin Blade," but his "Nichirin Blade" was quite different from the others', possessing unique characteristics.

With a loud "whoosh!", he pulled out an extremely long and heavy chain, one end of which was a sharp axe, and the other end a meteor hammer larger than his head...
