Lin Chen and the others had just arrived.
The estate's main gate had already opened.
A total of five people came to greet their arrival.
The Stone Pillar, Sound Pillar, Water Pillar, Wind Pillar, and Flower Pillar Kocho Kanae.
The current time point was four years before the start of the original story's plot.
At this time, the current generation's nine Demon Slayer Pillars hadn't yet been assembled.
For example, Wind Pillar Shinazugawa had only just become a Pillar this year.
"What powerful physique."
Tanjuro's gaze swept across the five people, coming to an abrupt halt only before the Stone Pillar.
Under the Transparent World, this man's physique was the strongest he had ever seen.
Simply monster-like physique.
Muscles as if cast from steel.
Completely on a different level from the others beside him.
If Lin Chen knew of Tanjuro's inner shock at this moment, he would only say it was very normal.
The Stone Pillar was completely an overpowered existence among the Demon Slayer's nine Pillars.
Counting physical talent and comprehension talent, among the humans who appeared in the original work, he ranked firmly in the top three.
At this current period, the other four Pillars were basically at the previous generation of Pillars' level, not yet grown to their peak.
But the Stone Pillar at this period was basically already approaching his peak.
In base state, he could basically pound any demon below Upper Rank Three. Four years later at his peak state, he could even pound Upper Rank Three in base state.
"Madam, and Miss Fujiwara, please follow me this way."
"This is where Master conducts business. The residential area is on the other side."
Kanae stepped forward, speaking gently and softly to Secretary Fujiwara and Kamado Kie.
She truly was quite a gentle person.
"Honestly, why can Lin Chen go in but I can't!?"
At this moment, Secretary displayed her demon-lord-level ability as an atmosphere destroyer.
She liked participating in all sorts of interesting matters.
Previously, she had noticed some interesting things about Lin Chen, but Lin Chen deliberately avoided her.
This time too—that Ubuyashiki family head who even her great-grandfather had highly praised had actually chosen to meet with Lin Chen.
Yet put her aside, the Fujiwara family's young lady.
Also Mr. Tanjuro—he too was hiding many secrets.
"Miss Chika, after learning your news, your family already rushed here yesterday."
"Especially your older and younger sisters."
Though not much older in age, Kanae was as accommodating as Secretary Fujiwara'smama-san, speaking warmly.
Her gentleness truly managed to restrain Secretary Fujiwara.
In the end, she obediently followed Kanae and left.
"Well then, Mr. Tanjuro and young Lin Chen, follow us to gorgeously meet Master."
The Sound Pillar spoke, his face full of brightness and vitality.
In the original work, Lin Chen quite liked Gorgeous Brother.
Back then, watching him lose an arm and go blind was quite distressing.
But seeing the ending, indeed boys who love to laugh won't have bad luck.
The arm-lost, eye-blind Gorgeous Brother already had the best ending in Demon Slayer.
"Master has been waiting for quite some time."
The Stone Pillar's voice was deep, his face covered in tears.
Making Tanjuro beside him quite confused.
On the other side, the Wind Pillar's expression was quite foul—didn't know if it was because of Giyuu beside him.
Walking into the estate, a man was already waiting here.
The man's temperament was gentle, but what left the deepest impression was that one of his eyes was quite distorted and ugly.
If Lin Chen were to describe it.
It was like the veins when activating Byakugan in Naruto, but appearing even more densely around the man's eye area.
And it wasn't normal skin color—it was an ominous gray.
"Mr. Tanjuro, Mr. Lin Chen."
"Some of the situation, I've already heard Mr. Sakonji explain."
Ubuyashiki Kagaya looked at Lin Chen and Tanjuro with a smile.
His voice carried a special magic that, entering the ears, had a calming effect on one's mind.
Even making one's head feel dizzy with a relaxed sensation.
This was a trait similar to Tanjiro's sense of smell and the Sound Pillar's hearing—could also be called a supernatural ability.
Ubuyashiki Kagaya was a natural-born leader.
Relying on his voice ability, he could easily draw close to others.
He also had a certain degree of precognitive ability, able to vaguely sense destiny's turning points.
In the original work, he had once predicted that this generation would completely resolve Muzan.
"These past days I've also looked up much information. Let's exchange details slowly."
Ubuyashiki Kagaya extended his hand, inviting Tanjuro and Lin Chen to sit before him.
A small table had already been set up here with tea water on it.
Tanjuro walked over and knelt before it. Lin Chen didn't like kneeling, so he simply sat cross-legged.
This time, Lin Chen didn't speak.
He played the role of observer throughout.
Instead, Tanjuro spoke in a gentle voice, recounting his Kamado family ancestors' story with Yoriichi.
He also described how over all these years he had trained in the Dance of the Fire God, as well as developing the Transparent World.
"Transparent World?"
The Stone Pillar's tears stopped. His gaze became serious, as if touched by something.
Tanjuro spoke, explaining in detail.
"If you want to open the Transparent World, the key lies in whether your breathing method and movements are precise."
"As well as whether you can exert maximum power with minimal movements."
"At the beginning, you must practice movements. As the five senses open, you must even recognize every single blood vessel in your own body."
"After remembering and absorbing many things, then close off the unnecessary parts in the movements, leaving only what that movement needs."
"Over time, the opening and closing of blood vessels and muscles in the body will be completed as quickly and simply as blinking."
"At that time, light will appear, and the path will open."
"Once the mind becomes transparent, you'll begin to see a 'Transparent World.'"
What Tanjuro described was exactly the Transparent World training method he had comprehended.
He had also told Lin Chen about this method.
But Lin Chen could only express: understood it, then what?
This basically required mastering every single blood vessel in the body, and that was just the beginning.
Lin Chen was helpless. He felt no spark of inspiration, because this realm was truly too far from him.
A realm only those who had undergone thousands of temperings could reach.
Just as Tanjuro said, to reach this realm, one must go through an extremely painful process.
"I see, so this is the Transparent World. How moving."
The Stone Pillar's tears suddenly flowed profusely.
He clasped his hands together, like a student, sincerely thanking Tanjuro.
At this moment, Lin Chen suddenly understood Secretary Fujiwara's gaze toward him in the snowy field before.
Now he looked at the Stone Pillar the same way.
Dude, you're actually that talented? So fast?
However, thinking of the original work, Lin Chen felt this seemed normal too.
Because the original was even more unreasonable—no one even told the Stone Pillar about the Transparent World's concept or the key to unlocking it.
He simply realized that Kokushibo seemed able to see a different world.
So he just directly unlocked it.
At this period, although his accumulation wasn't as deep as four years later.
Since Tanjuro had broken through that window paper for him, he naturally comprehended it along the way.
