I, Umo Tengen bravely venture into the world of Naruto

call out!

Teleport directly to the Demon Slayer Headquarters.

In the corridor in front of the inner room of the headquarters, the lord sitting here has been waiting for a long time.

"Tianyuan, you're here."

Ubuyashiki Yōya smiled and said hello to Utsuo Tengen, his bright eyes reflecting the colors of the setting sun.

"My lord!"

Yu Zhuan Tianyuan half-crouched down with a respectful attitude.

As for the crow that had been standing on his shoulder, it didn't react suddenly until Yu Zhuan Tianyuan leaned down.

"Gah?"

The small dark eyes moved back and forth.

The bird spread its arms and flew from Yu Zhuan Tianyuan's shoulders to the front of the lord.

"How is this done?"

"Is it the same 'magic' as Xiao Hei?"

That's right, as the loyal partner of the Lord of the Demon Slayer Corps, it is also the senior eagle crow that Xiao Hei calls him. It was also the one who asked Xiao Hei to teach the eagle crows the 'immortal arts' but unfortunately failed. proposed.

The way Yu Zhuan Tianyuan used it to teleport from the mansion to the headquarters in an instant surprised Dian Ya.

But associating it with the 'immortal arts' mastered by Xiao Hei, and the fact that the lord's body was treated by Yuzhuang Tianyuan and gained his current health, the bird gradually calmed down.

After being gently stroked on the head by the lord a few times, the crow flew alone to the big tree in the distance, knowing the rules.

After the crow flew away, Ubuya Shiki Yaoya said gently to Uku Tengen who was half-kneeling in front of him:

"Tianyuan, there is no need to be polite. I asked you to come here in such a hurry because I want to discuss something with you."

Ubuyashiki Yoshiya is very clear about what Uku Tengen, who can freely travel between two time and space, can bring to the Demon Slayer Corps.

Just like the explosion that happened last night, even though it was far away, he who stayed up all night waiting for news could clearly see the torn horizon.

The moment Shangxianzhisi and Shangxianzhiwu were killed.

After passing the message from Niu Ya, Uyashiki Yaoya had received the first-hand news.

He was not surprised at all by Yu Zhuan Tianyuan's timely support.

Because he had told him more than a month ago when Yu Zhuan Tianyuan left the magic mark at the headquarters.

If any evil spirits attack, pass the message to Xiao Hei, and Xiao Hei will have a way to summon him back.

And Xiao Hei used reverse channeling to summon Uku Tengen back, and it was Ubuya Shiki Yaoya who asked Yao Ya to pass on the news.

Yuzhuang Tianyuan's current strength is probably the strongest swordsman in the history of the Demon Slayer Corps.

Originally, swordsmen needed time to recover after a battle.

Ubuya Shiki Yaoya didn't want to summon Utsuo Tengen right away, but just this morning, he received the news that the evil ghost had been killed by a crow.

While he breathed a sigh of relief and immediately directed the arrangements for the aftermath, Ubuyashiki Yoya found a book on the corner of the bookshelf that he had neglected before he went blind. It was very thin, only had two or three pages, and had a very ugly appearance. It is a simple ancient book.

Out of curiosity, Ubuyashiki Yōya opened this ancient book.

The content recorded in the book was also the reason why Ubuya Shiki Yaoya immediately summoned Utsuo Tengen.

"Tianyuan, let's take a look."

The two of them walked into the inner room together.

After lighting the candle, closing the door, and sitting face to face.

Ubuya Shiki Yaoya handed the ancient book to Utsuo Tengen.

"This is……"

The first time he saw the ancient book, Yu Zhuan Tianyuan couldn't help but raise his eyes and glance at his lord.

The Lord smiled and nodded towards him, but the traces of curses that had begun to appear on his forehead made Yu Zhuan Tianyuan feel extra dazzled.

He pursed his lips slightly and opened the ancient book in front of his lord.

Looking at the ancient book in his hand, which only has two or three pages, it is densely packed with words.

Yu Zhuan Tianyuan's eyes were slightly opened, and he saw everything in his eyes...

Legend has it that during the Warring States Period, there were several first-generation swordsmen who were able to force the original ghost Wu Tsuji into despair. They all had lines similar to ghost patterns on their bodies.

Any swordsman with such lines will have an incredible improvement in strength.

The records in the ancient books are very detailed. Judging from the appearance of the ancient books, they must have existed for hundreds of years.

Such ghost-like patterns are called markings by the swordsmen who have them.

But at that time, many swordsmen died before they could awaken their patterns.

In addition, the pattern was not taken seriously at that time, and because the Demon Slayer Corps had suffered many major crises of destruction in its history, the method of pattern awakening was not passed down.

However, the last part of the record about the stripes seems to be recorded by a swordsman who awakened the stripes.

"Anyone who has markings will cause others around him to get markings as well."

These are all recorded on the first page of the ancient book.

The records on the last two pages of the ancient book all record a swordsman.

Yu Zhuan Tianyuan discovered the most critical words recorded in ancient books.

A powerful swordsman who was expelled from the Demon Slayer Corps because he failed to kill Demon Slayer Muzan.

Following Kokuenichi, he is the original swordsman who possesses the strongest sword skills in the world.

"The strongest sword skill?"

Seeing this, Yu Zhuan Tianyuan couldn't help but raise his eyebrows.

At this moment, Ubuya Shiki Yaoya took out another document and handed it to Uzuki Tianyuan.

"I got this from Makijuro after visiting him..."

Purgatory Makijuro, the predecessor of the Demon Slayer Squad, Enzhu.

Yu Zhuan Tianyuan nodded and took the information from the Lord's hand.

At the first glance of the above content, Yu Zhuan Tianyuan discovered the four characters "Breath of the Sun".

"Breath of the Sun?"

The records of the information are very detailed.

Breathing of the Sun, its status is the same as that of the original Ghost Dance Tsuji Muzan. It is the only strongest breathing method that has only appeared once in the world.

The five basic breaths of rock, fire, water, and wind are all derived from the breath of the sun.

Among the demon slayer swordsmen in the past, no one except the strongest initial swordsman can master it.

And the name of the original swordsman was Jiguo Enichi.

After Kunoyunichi was expelled by the Demon Slayer Squad, he disappeared from sight.

No relevant records about the 'Breath of the Sun' have been passed down.

However, at the end of the information, there is a sentence from Purgatory Makijuro.

"The Breath of the Sun has been lost..."

"But the 'Son of Hezhuo', who has crimson hair and red eyes and wears sun disk earrings, may be able to recreate it."

Makijuro's words were written in great detail, and Uku Tengen could tell at a glance that they were referring to Kamado Tanjiro, the swordsman in the Demon Slayer Corps who fights with demons on his back.

Yu Zhuan Tianyuan didn't speak, he closed the document gently and opened the ancient book again.

Following the country's fate, Breath of the Sun, Spots, Tanjiro...

Until all the words recorded in the ancient books are read.

After associating all these, after thinking for a long time, Yuzhuang Tianyuan looked at the lord in front of him with a solemn expression.

Asked: "My lord, what is your plan?"
