I, Uchiha Hikaru, join the chat group

The two deals have been settled temporarily.

Uchiha Hikaru thought for a moment: "By the way, Mr. Ubuyashiki. In addition to the nine pillars present today, I would like to ask you to summon another person... Kuwajima Jigoro, the master of my wife Zenitsu."

This person is the former Sound Pillar of the Demon Slayer Corps and the only person in the contemporary era who is proficient in the six sword styles of "Thunder Breathing". If you want to learn the complete Thunder Breathing, you must call him.

Since we are talking about this, Uchiha Hikaru also mentioned it by the way:

"Another disciple of Kuwajima Jigoro, Gion, once led a demon into the house when he was a teenager, killing a child in a temple, and causing your subordinate, Gion, to be mistaken for the murderer. If such a scum is allowed to stay in the Demon Slayer Corps, he will sooner or later become a disaster. It is recommended that you conduct a strict investigation."

"Gion...you mean the black-haired boy?"

Ubuyashiki Yoya looked surprised; "I will send someone to investigate this matter as soon as possible. No matter what the result is, thank you for your reminder."

...

Starting from the next day.

Bulma, accompanied by the lord's wife, Ubuyashiki Amane, who has long white hair, toured the city. Then, she used the remaining spare time to test the ore and sun blade samples sent by Ubuyashiki one after another, and transformed the original laser sword.

Tanjiro and the other two followed Kocho Shinobu to the Butterfly House and received special training from Kanao Kurika and others.

——By the way, they also met a blind date. After all, Tanjiro and Inosuke found their future wives in the Butterfly House.

Uchiha Hikaru began to learn the "breathing method".

After greeting Ubuyashiki Yoya, Uchiha Hikaru left his original body in the room and used the ghosts he had caught before to continuously practice the brainwashing ability of "Eight Thousand Spears". Then he split five shadow clones and followed four or five pillars to learn the "breathing method" at the same time.

Rock, flame, wind, water, love, snake, kasumi, insect, sound...

In addition, the former Sound Pillar who was just called by Ubuyashiki Yoya in a letter.

A total of ten breathing methods.

With the Sharingan plug-in turned on, there is basically no "breathing method" that Uchiha Hikari cannot learn after reading it once. If there is, then read it twice.

Then, she spent a few more days to master the "full concentration·constant concentration" of ten breathing methods.

The so-called "constant concentration" means that no matter when, even when entering a sleeping state, you can master the state of breathing with a fully focused attitude.

After mastering this state.

Uchiha Hikari soon discovered a fact-

"constant concentration" seems to increase the speed of chakra extraction and form a subtle blessing for the corresponding attribute escape technique.

For example, when maintaining "Flame Breath·Constant Concentration", releasing fire escape ninjutsu will be more labor-saving than before, and the power of fire escape will also be enhanced to a certain extent!

This is an unexpected surprise!

"The amplification effect of 'Changzhong' ninjutsu is about 5% to 10%. The more familiar and proficient you are in the ninjutsu, the more obvious the amplification will be... As your proficiency continues to improve, this number should have room for further improvement."

"Unfortunately, there is no clue about the 'transparent world' for the time being, and these pillars know nothing about it."

"In addition, different breathing methods cannot be used together for the time being. If they can be combined with the physical skills of the Naruto world..."

-This is another idea of ​​Uchiha Hikaru.

She had read the "Book of Seals" before and learned about the practice method of "Eight Gates of Ninjutsu".

In her opinion, this physical skill is not very suitable for her.

The first four gates can still be practiced.

But starting from the fifth gate, the "Eight Gates of Ninjutsu" has a high requirement for physical strength to the point of being harsh. If you don't have the physical skills talent like Kai and Xiao Li, plus crazy practice day and night, you may never have the opportunity to open more than six gates in this life.

In the Naruto world, there is also a physical technique called "Nine Days Breathing Method", which was created by Sunagakure. It also improves physical functions by adjusting breathing, which is very similar to the principle of the "breathing method" of the Demon Slayer Corps. The entry requirements are relatively low, but the enhancement is no less than the first six gates of the "Eight Gates of Dunjia".

Therefore, Uchiha Hikaru is thinking about whether he can develop a "Ten Days Breathing Method".

In principle, it should be feasible.

After all, Tanjiro once used "Water Breathing" and "Fire God Kagura" together, which made the advantages of the two breathing methods complementary, but they could not be maintained for a long time.

So, when she improves the "Changzhong" of these breathing methods to a higher level, she can make a try.

Speaking of which...

Uchiha Hikaru only suddenly realized a problem now-

In the original plot, when Tanjiro was fighting with Rui on Spider Mountain, at a critical moment of life and death, he awakened the ancestral memory engraved in his DNA, and then used "Fire God Kagura·Biro no Ten", which is a defective version of "Sun Breathing". Nezuko also awakened the "Blood Demon Art Explosion Blood" that can burn demons with blood in this battle.

But now...

Because of her intervention, Tanjiro and his sister have never seen tired, and naturally missed this opportunity to grow.

This is a bit troublesome.

Although she cosplayed as Tsugikoku Yoriichi, she is not the real Yoriichi reincarnation after all, and it is impossible for her to stay in the Demon Slayer World forever.

For the current Demon Slayer Corps, Tanjiro is the only one who inherited the "Sun Breathing" and is also the key figure in defeating Muzan. If he fails to awaken that memory... I am afraid it will bring a lot of variables to the future.

"...After the things here are finished, let's give them some guidance depending on the situation."

Uchiha Hikaru thought so.

…

Although the lord has already said something about Uchiha Hikari's "talent" in advance.

But the learning speed shown by Uchiha Hikaru these days still shocked the Demon Slayer Pillars.

Among them, Butterfly Ninja and Tomioka Giyuu already had some doubts about their qualifications as pillars.

However, Fusukawa and Purgatory Anjuro became excited after the initial surprise. They competed with Uchiha Hikari's shadow clone every day in the name of exchange and consultation, and never tired of it.

There is also Kanroji Mitsuri, this Koibashira is a familiar person. From time to time, she will bring several plates of cherry blossom cakes to Uchiha Hikaru to share, and then talk to her for a long time with an adoring look on her face, which makes Uchiha Hikari feel a little uncomfortable.

It’s worth mentioning that the Demon Slayer’s swordsmanship is generally pretty good.

Without much supernatural power to rely on, these swordsmen can only rely on honing their martial arts from generation to generation to fight ghosts, so they have some remarkable points in their swordsmanship skills. Especially the sword skills of fire, wind, and thunder, using the same strength and speed, can even suppress Uchiha Hikaru in a short time.

but……

Although their sword skills are very good, the next moment belongs to Uchiha Hikari.

She has used her Sharingan to copy a lot of sword moves in the past few days.

There is another person worth mentioning——

Yu Zhuan Tianyuan.

The sound column, who had been a ninja, quietly found Uchiha Hikaru when no one was around and asked if he could teach him some gorgeous ninjutsu.
