Line of Interval

One week later, after handling his father's funeral arrangements, Kujo Tachibana opened the final letter his father had left for him.

In truth, even now—ten years after arriving in this world and regaining his memories—Tachibana still had not figured out exactly what kind of place he had come to.

At first, Kujo Tachibana assumed he had transmigrated to nineteenth-century Japan.

However, as the years went by, Kujo Tachibana began to feel that something was slightly off.

Whether it was history, geography, or other factors, everything clashed with the memories of his past life.

It was not until today, through this final letter from his father, that Tachibana finally understood what kind of world he had truly entered.

"Tachibana."

"I have nothing left to teach you regarding the way of the sword."

"I only hope that, in the future, Tachibana can carry your father's legacy forward and continue to climb toward the pinnacle of swordsmanship!"

"The following words are very important; I hope you will remember them well!"

"In this world, there exists a terrifying species known as 'demons.' They possess sharp claws and fangs, strength comparable to wild beasts, and emerge at night to feed on human flesh and blood. Ordinary blades and weapons cannot harm them at all."

"Only sunlight and a unique weapon called a Nichirin Sword can sever a demon's neck and eradicate them completely."

"These Nichirin Swords are weapons forged only by a special organization known as the Demon Slayer Corps, which has been at war with demons for over a thousand years."

"Heh, Tachibana, do you think your father is joking with you?"

"I wish this were just a joke, and I hope even more that you never encounter a wicked demon."

Nichirin Sword, Demon Slayer Corps... these familiar terms flashed through Kujo Tachibana's mind.

Memories of his past life surfaced.

"Demon Slayer, huh?"

"Not bad."

Three months later, in the Kujo family courtyard.

Kujo Tachibana stood with both hands gripping a long, traditional Japanese katana, staring intently at the massive boulder before him.

This was his father's old sword.

The blade was 110 centimeters in total length, with an 80-centimeter edge that glinted with a chilling light under the sun. It was a true weapon of war!

Kujo Tachibana looked at the giant rock, holding his stance without striking, slowly adjusting his breathing.

Although Tachibana had not yet learned any Breathing Styles, he knew how to regulate his breath to better channel his physical power.

In Demon Slayer, before Tanjiro participated in the Demon Slayer Corps selection, his master Urokodaki Sakonji had set a grueling trial for him to ensure he wouldn't lose his life in vain.

That trial was to split a giant boulder with a sword. Ultimately, it took Tanjiro a year, with the help of the spirits of Makomo and Sabito, to perceive the Line of Interval and finally cleave the rock in two.

The boulder before Kujo Tachibana was a trial he had set for himself.

Only by cutting it could Tachibana leave the Kujo estate to search for traces of the Demon Slayer Corps; otherwise, traveling far from home would be too dangerous.

He wasn't afraid of encountering ordinary people.

He only feared the bad luck of running into a powerful demon in the wilderness, which would be troublesome.

Tachibana had no desire to be reincarnated again; who knew if he would get another chance at a fresh start?

He believed he could handle an average demon.

His swordsmanship was no weaker than the Hashira in Demon Slayer, and he had the added benefit of his Clear Sword Heart.

Kujo Tachibana thought, "If our physical stats were equal, the Hashira from the world of Demon Slayer wouldn't be able to beat me, right?"

It was just that without learning a Breathing Style, his physical constitution and explosive power were still significantly lacking compared to the Hashira.

As for the Line of Interval, Kujo Tachibana had perceived it half a year ago when he reached the realm of Clear Sword Heart, but his explosive power was still insufficient to split the boulder before him.

In Tachibana's understanding, the Line of Interval would guide you to the most fragile point in an object's structure.

Furthermore, if the object were in motion, the end point of the Line of Interval would not remain in the same place; the line itself would constantly shift.

However, given the density of the boulder in front of him, even with his perception of the Line of Interval, he had no confidence in his ability to sever it.

To cut this stone now, Kujo Tachibana felt there were only two paths.

First, learn a Breathing Style to increase his physical constitution and explosive power to cleave it.

But if he didn't leave home, he couldn't find the Demon Slayer Corps, and without finding them, he naturally couldn't learn a Breathing Style.

Therefore, Tachibana had to rely on the second method for now.

This second method was to continue studying the Line of Interval and develop the capabilities of his Clear Sword Heart, allowing him to observe the structure of objects at a deeper level.

It is like a house; if you want to tear it down, the most effortless way is to destroy its structural integrity, and it will collapse on its own.

For instance, the load-bearing walls, the support pillars, and so on.

However, Kujo Tachibana's current situation is that he can find the load-bearing walls, but he simply cannot smash through them!

So, what is to be done?

The method Kujo Tachibana thought of is!

Find the "load-bearing wall" of the load-bearing wall, and destroy the weakness of the weakness!

Kujo Tachibana: "I am going to smash the most important brick on your body!"

Of course, that is easy to say, but the actual execution is not so simple.

Three months later.

"Hah!!!"

Following a crisp sound of a sword ringing, there was no longer a giant circular boulder before Kujo Tachibana's eyes.

"Whew..."

Kujo Tachibana exhaled a breath of stale air with a pale face, endured the stabbing pain in his mind, and slowly sheathed his blade.

Looking at the fine gravel scattered at his feet, Kujo Tachibana rubbed his temples and couldn't help but sigh:

"This should count as splitting it, right?"

"The power of this move seems a bit too great."

"It's just that it seems to consume a lot of mental energy; my head feels like it's about to explode."

One week later.

Having sold the Kujo family ancestral home, Kujo Tachibana carried a wooden box identical to the one Tanjiro uses and a long cloth bag, leaving the small town where he had lived for fourteen years.

Actually, regarding the matter of selling the ancestral home as soon as his father left, Kujo Tachibana felt he still had something to say!

It wasn't that Kujo Tachibana wanted to be an unfilial descendant; it was truly that the Kujo family was already dirt poor!

His father, Kujo Kai, had been ill, which had already drained the last of the family's money. Then there were the funeral arrangements; in order to send his father off with dignity, Kujo Tachibana had already borrowed a lot of money, all of which was mortgaged against this ancestral home.

Add to that Kujo Tachibana's training and living expenses over the following half-year...

So, at this moment, Kujo Tachibana, alone and leaving his hometown, was in a financial situation no better than Tanjiro's family.

Watching the sunset over the distant mountains, Kujo Tachibana whispered softly:

"I heard the benefits and pay for the Demon Slayer Corps are quite high?"

"It seems I must hurry to find the trail of the Demon Slayer Corps."
