Chapter 140 Patterns

Following the old man's order, everyone quickly came to the area he pointed to and began to search in an orderly manner. Only then did they discover that the ancient books in this area were all related to the Demon Slayer Corps.

Looking at the old man who had already started flipping through the books with some curiosity, Busei asked him in a low voice.

"Why are books about the Demon Slayer Corps stored here?"

The old man did not hide anything. He turned a page with his fingers, stared at the contents, and explained to Busei Kawai very happily.

"Every generation of the Demon Slayer Corps' head has the ability to turn danger into fortune. Whenever Muzan and his minions were about to find the Ubuyashiki clan, the head would lead everyone and valuables to move to another place, and these books were among them."

Looking up at Busei who was listening with great interest, the old man raised a smile and continued speaking.

"But after a while, these useless books became bulky and took up too much space. They would only delay their transfer and hinder their evacuation. So, we asked the priests to keep them for us."

After saying that, the old man stopped talking and focused his attention on the ancient book in his hand. Seeing this, Busei didn't bother him anymore and walked towards the people who were standing in front of the bookshelf who were a little at a loss.

Looking at these countless ancient books, Wuyilang's eyes were dull and he spoke in a daze.

"When will I find this?"

Inosuke, who was standing by, heard the smile of mockery on his face. He bent his legs slightly, jumped with force, and jumped directly onto the bookshelf, looking down at Muichiro.

"Stupid brother Ichiro, you got scared after just reading a few books. Look how easily I found that...Yuji!"

Hearing Inosuke's provocation, without waiting for Muichiro to speak, Yuichiro looked up at him helplessly with his eyes rolled.

"You didn't even pronounce the name correctly... and can you really read?"

Seeing the questioning expression on Yuichiro's face, Inosuke on the bookshelf was almost mad. He somersaulted down and yelled at Yuichiro.

"You bastard, of course I can read!"

Then he picked up the book and started reading, determined to find Yuichiro's trace first and prove it to Yuichiro.

Ignoring the three children's noise, Tianyin looked at the wolf who was frowning and silently flipping through ancient books, and asked him softly.

"Mr. Hirata, do you have any clues about Yoriichi?"

Putting down the book in his hand, Wolf was not good at getting information from books. If Jiulang was here, he might be able to find clues quickly. Now facing Tianyin's question, Wolf could only shake his head helplessly.

At this time, Busui River came forward from behind and spoke to the two of them.

"In that case, then let's do our best to find it."

Time passed slowly. Being underground, the air circulation was poor, and coupled with the boredom of reading books, everyone except the wolf looked drowsy.

Just as everyone was about to close their eyes, Wolf's calm voice rang out.

"found it…"

Hearing this, the three children immediately perked up and came to the wolf, squeezing their heads to see the content of the book they had been looking for for a long time.

But before he could see clearly, he was thrown and kicked two meters away by Busei. Seeing how curious they were, Wolf hesitated for a moment and began to tell the story described in the book in a flat voice.

It is said to be a book, but if you look closely you will find that it is actually a biography, most likely written by a pillar of the Demon Slayer Corps of an unknown generation.

The biography writes how difficult it was to kill demons in the early days of the Demon Slayer Corps when there was no breathing method, and later, when Yoriichi joined the Demon Slayer Corps with the breathing method of the original, and was shocked when he saw his powerful strength.

But... the original breathing is so difficult that almost no soldier can master it.

The second most described thing in the chronicles is that Yoriichi created a breathing method that was more suitable for the members of the Demon Slayer Corps through the original breathing.

Hearing these old news, Busei was slightly surprised that the breathing method was actually created by Yoshiichi. At the same time, he became puzzled as to why such a good thing was not widely circulated among the Demon Slayer Corps, but was hidden in this dark library.

But then the wolf told him the answer by telling them the rest of the story.

According to the person who wrote the biography, Yoriichirō had a scar on his forehead that looked like a flame, and after he joined the team, many powerful members of the team also developed strange-looking scars.

After growing such a scar, the soldier's strength made a qualitative leap, and the strength of the Demon Slayer Corps was greatly improved. Everyone named him - Mark.

During that time, evil spirits dared not do evil and could only hide in the darkness, and the world ushered in a rare peace.

Everyone was sighing that it was the appearance of Yunyi that brought about the breathing method and the markings, and that he was the undisputed hero. But whenever someone said this, Yunyi would blush and shake his head humbly like a child.

But... the good times didn't last long. When the first spotted swordsman died mysteriously on the night he turned 25, a voice spread among the Demon Slayer Corps...

Those who have the markings activated will not live past the age of twenty-five.

The Demon Slayer Corps was suddenly in a panic, not because anyone was afraid of death, but because they were worried that without the high-end combat power of the Marked Swordsman, evil demons would wreak havoc on the world again.

Knowing that it was because of him that the Demon Slayer Corps opened their marks, Yoshiichirō frantically searched for the trace of the Demon King, Muzan Kibutsuji, during that time.

But just when he was about to severely injure Muzan, when he returned to the Demon Slayer Corps, he was faced with the condemnation of the Demon Slayer Corps.

Because his elder brother, Tsugumi Iwakatsu, was afraid that opening the mark would cause him to die at the age of 25, so when Yoriichi left, he cut off the head of the current lord of the Demon Slayer Corps and defected to Muzan in order to gain a long life.

Faced with everyone's blame and even being asked to commit seppuku, Yoriichi didn't say anything. He just stood there blankly. Fortunately, the current Flame Pillar, the owner of the biography, and several other Pillars spoke up for him.

Finally, under the protection of the successor head of the family who had just lost his father at the age of six, Yoriichi was finally expelled from the Demon Slayer Corps and faded out of the sight of the Demon Slayer Corps.

Not long after, the owner of the biography died at the age of 25 due to the opening of the markings...

The biography ends here...and everyone's face is different, Wolf lowered his head with a gloomy look, Fuzugawa is thoughtful, and Tianyin is full of guilt.

"I didn't expect the truth about the stripes to be like this..."

Hearing Tianyin's sigh, Busei turned his head to look at him with a look of confusion on his face.

"Master Tianyin knew about the stripes, why didn't you tell us."

Tianyin shook his head and explained to Busui River.

"I don't know if it's because there are too few swordsmen who survived, or for some other reason, but the Demon Slayer Corps' records of the markings are far less detailed than in this biography, but there is one thing that is described very clearly."

"Once the markings appear, the people around them will also awaken their markings one after another as if in resonance."

"And there are many swordsmen who have been unable to awaken the markings and have been unable to recover, so they concealed the matter of the markings."

Hearing this, the wolf, who lowered his head with a gloomy face, suddenly had his pupils shrink.

When Busei heard what Tianyin said, he held his chin and spoke thoughtfully.

"So, after Kokushibo resurrects Yoriichi, the markings will reappear, and we will also have a chance to activate the markings."

The wolf heard these words with a hint of excitement, and he raised his head with his pupils constricted.

But what he saw before him were the Butterfly Sisters, Uzui, Busei, Giyuu and others with strange ghost-like lines on their faces, and they stood in front of him with empty eyes and no life at all, staring at him quietly.

His pupils trembled violently at this moment and his mouth opened slightly.

"...The strength gained at the cost of one's life... is not something to be thankful for..."

Hearing this sound that made people feel like they were falling into an icy cave, everyone was surprised and turned to look at the wolf who now had a murderous look on his face.

But he saw his right hand subconsciously reaching behind him and climbing onto the handle of the ancient sword behind him, and a cold voice squeezed out from between his teeth.

"...kill him..."
