Ghost Slayer: The Great Swordsman System at the beginning, our teacher follows the country

"Open your mouth."

As he spoke, Secretary Shu opened the potion jar.

With a flick of his wrist, the liquid accurately flew into the mouths of the Butterfly Ninja and others.

Soon after swallowing the potion, their faces began to turn a little red.

The flesh and blood of the missing limb twisted, as if something was about to grow out of it.

Immediately afterwards, like the secretary before them, a large amount of bones and flesh poured out of their bodies.

Eggs of different colors are formed one after another.

"That's pretty much it."

Seeing Dan's appearance, Si Shu nodded.

"The rest is to wait."

"But... doesn't it take time to become a ghost?"

Before Tamashi could speak, Yushiro spoke first.

"You didn't know this, but this bottle of potion was improved by me."

"After taking it, the time to become a ghost can be reduced by half."

"It can be shortened significantly."

As he said that, Yushiro's face showed a hint of pride.

To be able to develop a ghost-turning potion to this extent, he is considered a genius.

But at this time, Tanjiro said again.

“But even if it’s shortened by half, it’s still not enough time.”

Hearing this, Yushiro's face froze.

Tanjiro was right.

The more powerful a swordsman is, the longer it takes to become a ghost.

Especially for swordsmen with column-level strength, each one's transformation into a ghost takes hours.

It is even measured in days.

One night is obviously not enough.

But Secretary Shu smiled slightly.

"Have you ever considered why it takes so long to become a ghost?"

"why?"

Tanjiro was very confused and turned to look at Yushiro.

But Yushiro shook his head and turned to look at Tamashi.

Jushi sighed and said.

"Because ghosts and humans are two completely different races."

“Conversion takes a lot of time.”

Secretary Shu nodded, agreeing with Zhu Shi's theory.

But he continued to ask.

“So why does conversion take so much time?”

Once this question was asked, everyone fell silent.

Secretary Shu didn't hide anything and explained with a smile.

"Because it requires energy, a lot of energy."

"It's also powerful, the more energy it requires for transformation. Naturally, the longer it takes."

"In other words, as long as powerful energy can be provided, the time for ghost transformation can be shortened."

Hearing what Si Shu said, Zhu Shi seemed to have understood what he meant.

"You want to use your own thin blood?"

"good."

Si Shu opened his wrist and controlled his muscles to stop healing.

Then he waved his wrist, spilling a large amount of blood.

The blood spilled onto the egg and was absorbed instantly.

After absorbing enough blood, the light on the egg became richer.

"In about three to 10 minutes, some people will be successfully transformed."

Pressing his fingers on his wrist, the wound disappeared.

At the same time, Secretary Shu looked at Tanjiro and others.

"By the way, take advantage of this time to bring the Nichirin Sword over."

"bring it here?"

"Of course, otherwise how can I forge a knife?"

With a surprised expression on his face, Tanjiro seemed not to have expected Secretary Shu to answer like this.

"Can you also forge knives?"

"Is it difficult to forge a knife?"

Secretary Shu raised his hand and waved, and a line of blood flew out.

Soon after, the Nichirin sword he dropped was brought back.

"I forged this knife myself."

Tanjiro was silent.

Nezuko was silent...

Inosuke, my wife Zenitsu and others were also silent...

In the end, they brought back the broken Nichirin Sword.

After looking at it, Secretary Shu nodded slightly.

"The fragments are all there."

"Okay, you guys take a few steps back."

"I'm going to start."

After speaking, Secretary Shu's palm rushed out of the bones.

After a period of twisting and combination, they circled together.

Then he raised his hand and threw the sorted broken blades into it.

The next second, the red blood burning flames burned fiercely.

At extremely high temperatures, it didn't take long for the nichirin sword to begin to soften.

Just when Tanjiro was about to ask Si Shu what he used to hit, he saw Si Shu raise his right fist.

"Ping~"

He punched out and hit it hard, making the sound of gold and iron clashing.

Secretary Shu's fist was like a hammer, constantly hitting the sun blade.

At this time, Tanjiro and others were dumbfounded again.

Physical forging?

If such a skill were seen by a swordsman, he would probably call it a magical skill.

A few hundred years ago, it would have been impossible for anyone to do this.

Under the forging of Si Shu, the Sun Lun Sword quickly condensed into shape.

Finally, Secretary Shu threw the forged knife into the air and sprinkled blood on it.

Only a stabbing sound was heard, and a large swath of blood-colored mist sounded.

A brand new Nichirin sword was completed and appeared.

Compared with the previous one, this new Nichirin sword has not changed much.

It's just that there's a little more red on the sword, which is extremely dazzling.

At first glance, it feels like your eyes are going to be burned.

Tanjiro recognized it as the butterfly ninja's sword.

"When Shinobu comes out, let her try it."

Before Tanjiro could nod, there was a sound of breaking from one of the eggs not far away.

Then a figure walked out of it.

The body is covered with lavender scales, and the butterfly hair ornament behind it highlights its identity.

The purple at the ends of the hair is more intense, and there are a few more unknown purple lines on the neck.

There are two short transparent whiskers above the forehead, like butterflies.

Insect Pillar, Butterfly Ninja, and Demon Transformation completed.

Feeling his body that had been transformed into a ghost, Shinobu truly realized why humans couldn't resist ghosts.

The physical gap alone is enough to crush 90.00% of humans to death.

She had never thought that her physical condition would be as good as it is now.

"how do you feel?"

The secretary's voice came, and Butterfly reluctantly looked around.

After discovering that Secretary Shu was forging a knife, shock flashed across his face.

But after reacting, he still nodded slightly.

"It feels good."

"That's good, let's try the new knife."

As the Butterfly Ninja picked up the Nichirin Sword, a hint of joy flashed across her face.

The Nichirin Sword seems to be one with his body, like an extension of his arm.

Regardless of each other, they form one body.

This sword alone can increase one's combat effectiveness by more than [-]%.

"Thank you, Mr. Secretary."

"You're welcome, just feel free to use it."

The secretary responded, and then continued to devote himself to forging the sword.

Over time, more and more eggshells break.

One after another, figures exuding a terrifying aura appeared in this world.

"Kanae, the rabbit, the wild dog, Kuangyin."

"This is your knife."

After several new people took the knife and tried it, they also praised it full of praise.

The Butterfly Ninja also discovered that Si Shu's sword forging sequence was very clever.

It is exactly the same sequence as the ghost awakening.

There is no deviation.

"Has Mr. Secretary Shu's estimate of our strength already reached this level?"

After a long time, all the bullet casings shattered.

All the powerful members of the Demon Slayer Squad have turned into ghosts.
