I was writing a diary in Demon Slayer, and the butterfly ninja honey glass was broken.

When you see it, the straight blade is about the length of a fingernail, pale silver, and the tip has a quadrangular upward slope.

At the handle is an octagon, and Su Yu draws a concept map for Ying Crow to take to the Forging Dao Village.

The pattern drawn on the design drawing is based on an animation and a tokusatsu film he watched in his previous life.

The Adventures of Lolo - Supersonic Ice

Sword Magic Bullet Battle - Dragon Sword of Dragon Kendo.

It's just that the weapon in front of me is more angular and more handsome to see.

Su Yu picked it up, and the heavy feel made him very satisfied, and he asked Tie Xuesen, "How to split?" Tie Xuesen

replied: "There is a slightly protruding "trigger" at the top of the side of the grip, and it is pulled three times in a row.

After Su Yu did so, the one-piece broadsword split in two and turned into two single-edged straight knives!"

Butterfly Shinobu looked at Su Yu, who seemed to have obtained a new toy, and smiled.

"yes, it's better than I thought, it's really troublesome for you, Mr. Tetsukumori. Su Yu weighed his Nikkawa knife and tried to swing it.

Whether it is combined or separated, it is very convenient.

Tie Xunsen smiled, "Then come and try it and see what color your blade will become."

Su Yu moved in response to the sound and shook the blade hard.

In the next second, the inky pure black changes color from the bottom of the blade and continues upwards until it covers the entire blade.

"Oh, oh, it's actually black, this is really unexpected, I saw it for the first time." Tie Xuan Sen said.

"How can it be a black blade?" muttered Kana, a little surprised, "The color of the blade usually changes with the holder, but basically those colors." Butterfly

Shinobu also nodded lightly, looking at Su Yu's face was flat, he seemed to know that his knife would turn into this color?

"I'll go change first!" Su

Yu immediately picked up his clothes and the Nikkiro knife and went to the next room to change.

"This guy, you have to bring a knife when you change your clothes, so reluctant. Butterfly couldn't help but laugh.

When he returned to the reception room, the eyes of both girls lit up.

A white haori that extends down from the shoulders is draped over her body, and inside is a black ghost slayer uniform.

Su Yu, who is in his early eighties, is majestic in his clothes, and no one does not believe that he is a captain-level figure.

Su Yu moved his shoulders, very comfortable.

When he left to change clothes, he also put "Undead Killer" and "Flaming Sun Thorn" on his Nikkawa Knife and Ghost Killer Team uniforms respectively.

"I don't know if this kind of weapon that can be split in two, whether the enchantment will also be split in two, if it can, it will be a big loophole." He thought to himself.

The reason why I wanted to create such a strange shape of the Nikki knife was also because of this idea.

Su Yu looked at Xiang Naihu and said with a smile: "How many tricks will accompany me?"

The

two walked to the courtyard, Su Yu used the Nikki broadknife she had just obtained, and Xiannehu used her normal style of Nikkaku.

Bang ~ bang ~

The two knives collided, making a crisp sound.

Su Yu's heart froze, his steps moved slightly, his figure moved instantly, appeared behind Xiangnaihu, and raised his hand to slash.

——!

Kana reflexively blocked, but was shocked back several steps by a strong force.

She steadied her figure, and her pretty face showed a surprised expression.

Just now, she was actually suppressed?

"The strength is very good, then I will win with speed." Chanel

stepped on his feet and disappeared.

Using Flower Breath, she is extremely fast.

"Come!" Su Yu rushed up with interest.

The two men engaged in a fierce confrontation in the courtyard, with blades colliding and fists bombarding.

Every confrontation causes an air boom and a splash of Mars.

The two people were fighting lively in the courtyard, and Tie Xunsen was surprised to see it.

"I remember that Xiannaihu is your stepson, Su Yujun can actually fight with her back and forth, and her strength is very strong." Butterfly

Shinobu was a little stunned, and the doubts did not come out, but repeated in his heart.

"Strange, this is not the kind of sword technique he used before, this is... Breathing method?" This

reminded her of a pillar-level genius in the Ghost Killing Team, Shi Tou Wuyilang.

At only 14 years old, it only took him two months to become a pillar, and his talent was extremely terrifying.

Su Yu told himself seven days ago that he could find a better breathing method, and he actually mastered it now, how terrifying this talent was! There was

a loud noise in the courtyard ——!

.

The two jumped back for some distance, stopped their offensive, and glanced at each other.

"I lost," Su Yu smiled helplessly and said, "When I meet a real master, I'm still too weak in terms of breathing methods. He

can be regarded as experiencing the feeling of Tanjiro training against himself, and

with the bonus brought by "Solon Kendo", he can still defeat him by fighting Tanjiro.

But Channahu, the combat power is already able to rank among the high-level swordsmen of the Ghost Killing Team.

Further on, it is the level of a pillar-level swordsman.

Her ability to come out spotlessly from the vine attack mountain has proved her strength.

In terms of the attainment and use of the breathing method, she is definitely the chief of the new members of the Ghost Killing Team, and Su Yu also sighs to herself.

"You're just losing at proficiency, you're strong, and if you are allowed to exercise for a while, I may not be your opponent."

Kana smiled, her fair forehead covered with beads of sweat, and she didn't look easy to win.

Even so, her eyes were still staring at Su Yu brightly.

A person who has just learned the breathing method for seven days can achieve this level, which is enough to be called talented!

As a fighter, Kana can feel that he wants to integrate the breathing method into the combat technique he uses.

That super combat technique that can instantly cut the neck of the hand ghost, but he still didn't use the breathing method.

Chana thought of this, and her eyes brightened.

"Let's take a break and go on!" she said.

The corners of Su Yu's mouth tugged, his breathing was slightly disordered, and he smiled bitterly in his heart.

It seems that the little girl is planning to use herself as a sandbag to practice.

Fortunately, people with this level as opponents have more room for improvement.

So

, in the following time, Su Yu practiced against Xiangnai Hu for two or three hours, and the result was still more losses and fewer wins.

Xiannaihu's attainment of the breathing method is really not Su Yu can catch up in a short time, simply using the breathing method, Su Yu is still a rookie.

So much so that most of the time he was beaten and became blue and swollen.

Xiannehu's little pink fist pounded, but with dozens of pounds of strength, he almost didn't beat Su Yu to death.

Kana said with a smile: "Your understanding of the breathing method is still too rigid, only used when moving and swinging a knife, and you should always maintain the operation of the breathing method during the battle."

"You mean, 'fully focused breathing,'"
