I, Hikaru Uchiha, join the chat group

The two deals have been tentatively agreed.

Uchiha Hikaru thought for a moment: "By the way, Mr. Uyashiki. In addition to the nine pillars present today, I would also like to ask you to summon someone... my wife Zenitsu's master, Kuwashima Jigoro."

This person is Naruhashira, the predecessor of the Demon Slayer Corps, and the only person in the contemporary era who is proficient in the six sword types of "Thunder Breath". If you want to learn the complete Thunderhu, you must call him.

Now that the conversation has come to this point, Uchiha Hikari mentioned by the way:

"Another disciple of Kuwadao Jigoro, Yue Yue, once lured ghosts into the house when he was young, killing a child in the temple, and caused your subordinate Bei Mingyu Xingming to be mistaken for the murderer. If such a scum are allowed to stay, The Demon Slayer Corps will become a scourge sooner or later, so I suggest you investigate it strictly."

"Hongyue...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 the reminder."

……

Starting from the next day.

Bulma was accompanied by the lord's wife, Uyashiki Amane, who had long snow-white hair, and went sightseeing in the city. Then, he used the remaining free time to test the ore and Nichirin sword samples that Usanyashiki had sent one after another, and to modify the original laser sword.

Tanjiro and the other three followed the Butterfly Ninja to the Butterfly House to receive special training from Kurihana Rakanahu and others.

——Let’s go on a blind date by the way. After all, Tanjiro and Inosuke found their future wives in Butterfly House.

Uchiha Hikaru started learning the "breathing method".

After greeting Ubuyashiki Yōya, Uchiha Hikaru left his body in the room and used the ghosts he had caught before to continue practicing the brainwashing ability of the "Eight Thousand Spears". Then five more shadow clones were separated, and they followed four to five pillars to learn the "breathing method" at the same time.

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

In addition, his ex Naruhashira was just called by a letter from Uyashiki Yoya.

There are ten breathing methods in total.

When the Sharingan plug-in is turned on, there is basically no "breathing method" that Uchiha Hikaru cannot learn after watching it once. If there is, then watch it twice.

Then, she spent a few more days and mastered the "Complete Concentration·Changzhong" of ten breathing methods.

The so-called "constant" refers to the state of being able to master breathing with full concentration at any time, even if you fall asleep.

After mastering this realm.

Uchiha Hikaru quickly discovered a fact——

"Changzhong" seems to be able to increase the speed of chakra refining and provide a subtle blessing to escape techniques with corresponding attributes.

For example, while maintaining the "Breath of Fire·Constant", releasing the Fire Release Ninjutsu will be more labor-saving than before, and the power of the Fire Release Ninjutsu will also be enhanced to a certain extent!

What a surprise!

"The Ninjutsu amplification effect of 'Changzhong' is approximately between 5% and 10%. The more familiar and proficient you are with the escape technique, the more obvious the increase will be... As your proficiency continues to improve, this number should still increase. There is room for further improvement.”

"Unfortunately, we don't have a clue about the 'Transparent World' yet, and we don't know anything about these pillars either."

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

——This is another idea of ​​Uchiha Hikari.

She had already read the "Book of Sealings" before and learned about the cultivation method of "Eight Doors Dunjia".

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

The first four doors can still be practiced.

But starting from the fifth gate, the requirements for physical strength of "Eight Gate Dunjia" are so high that they are almost harsh. Without the physical talent of Kai and Xiao Li, coupled with the crazy practice day and night, there may not be a chance to open more than six doors in this life.

In the world of Naruto, there is also a taijutsu called the "Seven Heavens Breathing Technique", which was created by Sunagakure. It also improves body functions by adjusting breathing. The principle is very similar to the "Breathing Technique" of the Demon Slayer Squad. The entry requirements are relatively low, but the enhancement is no less than the first six doors of the "Eight Doors Dunjia".

Therefore, Uchiha Hikaru was wondering whether he could develop a "Ten Heaven Calling Technique".

In principle it should be possible.

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

Therefore, when she can improve the "constancy" of these breathing methods to a higher level, she can give it a try.

Speaking of which...

Only now did Uchiha Hikari suddenly realize a problem——

In the original plot, when Tanjiro was fighting with Rei on Spider Mountain, at a critical moment of life and death, he awakened the memory of his ancestors engraved in his DNA, and then used "Kagura, the God of Fire, Hiro no Ten". It's the incomplete version of "Breath of the Sun". It was also during this battle that Nezuko awakened the "Vampire Technique: Blood Explosion" that can burn ghosts with blood.

But now...

Because of her intervention, the Tanjiro brothers and sisters never saw Tired, and naturally they missed this opportunity for growth.

This is a little troublesome.

Although she cosplayed with Enichi Tsukuni, after all, she is not the real reincarnation of Enichi, and she cannot stay in the Demon Slayer World forever.

For the current Demon Slayer Squad, Tanjiro is the only one who has inherited the "Breath of the Sun" and is also the key figure in defeating Muzan. If he is unable to awaken that memory... I am afraid it will bring consequences to the future. Lots of variables.

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

Uchiha Hikaru thought so.

……

Although the lord has already said something about Uchiha Hikaru'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, the Immortal River and Purgatory Anjuro became excited after the initial surprise. They competed with Uchiha Hikari's shadow clone every day in the name of communicating and asking for advice, 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 pull her to talk to her for a long time with an adoring look on her face, which makes Uchiha Hikari 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.
