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

"Why do you think so?" Su Yu was a little stunned.

Tanjiro caressed Youdouko's head and said with a sad wry smile.

"You see, Oni Mai Tsuji was killed and hid by the user of the Breath of the Sun, and now he has killed my family again, and I happen to be the inheritor of the Breath of the Sun, this... Isn't it predestined?

Su Yu was silent.

If so, it's really true, who made him the protagonist of the comic.

But in fact, seeing a boy several years younger than himself say this, Su Yu couldn't help but feel sad.

The ghost killing team is full of young people, and they carry so much at a young age.

When Su Yu thought of this, he had to sigh.

"It's okay, this has strengthened my desire to eliminate Oni Mai Tsuji.

Tanjiro saw Su Yu's unbearability, but a relieved smile appeared, as if something was relieved, and said:

"Su Yu-kun, thank you, if you still want to know more details of the fire god Kagura, that is, the breath of the sun, I can show you a few more times." "

Ah thank you, wait, you-"

Su Yu subconsciously thanked and realized that something was wrong.

Tanjiro's eyes were clear and had a "clear" smile.

Did he see his intention to come to him?

"I don't think there is anything wrong, since this breathing method will be lost, and even only a derivative version has been passed down to this day, I think it should be very difficult, and it is a

fluke that I can learn it, so if you want to learn and can learn it, I believe the founder of Breath of the Sun will also be very happy." "

Tanjiro's cleverness is on display at this moment.

He didn't even ask Su Yu why he knew this, he only knew that he was grateful to Su Yu for telling him these things.

This also gives Tanjiro more motivation and direction to move forward.

"We will still have the opportunity to meet, go to the nine-pillar training, that can make your strength improve rapidly, and help your family avenge early."

Su Yu said: "Don't hold back everywhere because you are the eldest son in the family, you also have the right to vent your voices, and I will help you share a little in the future."

Tanjiro opened his mouth, and the words reached his heart, and immediately, his eyes were slightly red with a "hmm".

After not having to hide his head and tail, Su Yu and Tanjiro exchanged ideas, and swaggered to use the breath of the sun.

The speed of his progress made even Tanjiro feel a lot of emotion.

At first

, the two used wooden knives to compete, and Su Yu was still hit by Tanjiro.

His breathing was always forked, and the next second he was slashed in the head by Tanjiro, causing him to grin in pain.

It was clear that he was practicing against him, but Tanjiro always hit him, and immediately came over to apologize and ask if he was okay.

With this attitude of the other party, Su Yu felt that he was really an angel.

However, the condolences after the hit were angels, and before the hit, he really did not spare a hand.

Su Yu is very satisfied with this attitude, and it is also true for ghosts, Tanjiro will not skimp on his kindness,

but that is also after cutting off the ghost's head.

Before this, he would spare no effort to cut off the head of the ghost.

Soon.

The situation has been reversed.

Just the next day, it became Tanjiro who could not withstand Su Yu's attack.

Although the learning of breathing methods is much behind, Su Yu's practical combat skills are much stronger than Tanjiro.

Killing twenty-six ghosts in the mountains in one night relies not only on the good of weapons, but also on the combat ability brought by "Solon Kendo".

After a little introduction to the breathing method, he also began to consciously use the breathing method.

It was indeed a very miraculous method, and as soon as I breathed, I felt that my whole body was filled with indescribable power.

The already strong body, under the addition of the breathing method, attacked rapidly.

As long as the body is strong enough, the bonus brought by the breathing method will be more lasting and powerful.

And Su Yu had a body that was strengthened after signing in the diary at the beginning, and Tanjiro's physical fitness was far less than him.

As a result, Tanjiro was exhausted after every battle, while Su Yu looked calm and relaxed, and did not seem to spend too much effort.

In the end, Tanjiro was defeated.

He lost, he lost without complaint.

Because his physical strength is simply not comparable to Su Yu.

However, after the discussion, Tanjiro also benefited a lot from Su Yu.

The time here is extremely short.

For seven days, Su Yuquan was competing with Tanjiro.

After the seventh day, Tanjiro's Nikwa knife was delivered, and Su Yu also took his leave.

He couldn't wait to go back to the Butterfly House to see his Nikkaku Dao.

"Su Che-kun, thank you, when I finish a few tasks, I will go to the Butterfly House to find you!"

said Tanjiro beckoning to Su Yu who was descending the mountain.

Su Yu also turned around and beckoned to him, "See you in training!" Immediately,

he took out the tracking compass and rushed back without stopping.

Back to the back of the butterfly.

He had just pushed open the door and happened to bump into a person.

Su Yu was fine, but the other party was knocked down.

"I'm sorry, I'm a little rushed, you're okay." Su Yu stretched out his hand to the person sitting on the ground in front of him and said apologetically.

The man suddenly raised his head, causing Su Yu to jump back subconsciously.

It was a mask with a long mouth and a red face.

This is exactly the mask that the people of the Nikki knife forging knife wear, the fire man.

"Presumably you are Mr. Su Yu, right?" came a nice voice from under the mask, he himself got up from the ground, dusted and said, "I am a knife forging man, named Tie Xun Sen, the first time to forge a double knife, put it in the reception room, I don't know if you will be full..."

Before the word "Yi" could be spoken, Su Yu didn't care about politeness, and directly grabbed his hand and ran into the butterfly house, "Take a walk, take a look!"

"Nor is that.

"Where is the reception room, what is this yard doing so big!" Su

Yu pulled the forger to run around.

"Mr

. Su, wait..." "Mr. Su, the conference room is..." "Mr.

Su, listen to me!" Su

Yu stopped and looked at him panting, "What?" The

expression under the mask of Tie Xunsen was extremely strange, pointing somewhere, and said: "The reception room is obviously in the second room in the left corner of the front, how did you run back and forth to avoid that room perfectly." "

Is it?" Su Yu stepped forward, and after a few steps, he suddenly turned a step to the right.

Seeing this, Tie Xunsen quickly stepped forward and pulled him back and walked to the right.

It didn't take a few steps to reach the reception room.

Butterfly Shinobu and Xiang Naihu were actually inside, and when they saw them come in, they both looked at Su Yu with a smile.

"You can get lost indoors, Yu Jun, you road idiot - I'm so sorry, Mr. Tie Xunsen, let you run away for so long." Tie

Xiansen touched his head, and his expression under the mask was slightly helpless.

Su Yu didn't pay attention to this, he saw two boxes on the table in front of him.

One of the rectangular wooden boxes, which was slightly wider than his forearm, saw that it was his own daywheel knife, and Su Yu couldn't wait to go.

Tie Xunsen wiped his sweat and said.

"Your request is very special, requiring a broadknife to be split in two, the separate knife is a straight-edged knife, with a C-shaped gauntlet, fortunately, I built it. "
