Total concentration breathing.

A general term for the technique of fighting demons with human beings, developed by the Demon Slayer Squad. It is mainly used to strengthen the heart and lungs, so that the blood can absorb a large amount of oxygen, which can greatly increase the body's ability in an instant, and have the same physical ability as a ghost.

In addition, there is also the all-day concentrated breathing method 'All Concentration-Constant Concentration', which allows you to concentrate on breathing even when you are asleep, which is the minimum condition for approaching the strength of the column.

Although it was still night, Mr. Lin Long didn't want Xia Ruo to sleep at all, and directly began to explain the use of the breathing method.

"Take a deep breath and let oxygen into every cell of yours, so that your body's ability to heal itself will naturally improve, which can make your mind calmer, think more flexibly, and ...... next"

Regarding the breath of water, Mr. Lin Long spoke in detail, and Xia Ruo also remembered all the details.

Soon, the system beep appeared.

【Ding! You can directly learn the breathing method 'Water Breathing', which costs 500 Fame. 】

The system can learn skills directly in the animation world.,It's just that you need some prerequisites.,For example, you need to have a magic scroll.,Cheats.,Or the teacher's teaching to learn.,It seems,Mr. Rintaki knows that meets the learning conditions of the system.。

It's just that learning the breathing method only consumes 500 prestige points, which Xia Ruo didn't expect.

The last time I studied magic at the soup house, the reputation consumed was from several thousand prestige, even if it was daily magic.

Xia Ruo thought about it, and in fact, he could understand that he had studied the learning mode and consumption of the system.

When systematically learning a skill, the reputation consumed is not divided according to the power and level of the skill.

The degree of prestige consumption is mainly divided according to the reasonableness of skills.

For example, real-world guitar skills and fighting skills can be learned with only a few points of prestige, which means that those skills are reasonable and can be learned by humans.

And magic and witchcraft curses, which are extremely unreasonable skills in the real world, consume a lot of prestige, and it takes thousands of prestige to learn, and the more unreasonable the skill, the more prestige it consumes.

In the system's prompt, it only takes 500 reputation to learn Water Breath, which means that this Water Breath, which uses breathing to improve cardiorespiratory ability, is considered by the system to be more reasonable than magic and sorcery.

"What are you doing, why don't you breathe as I say you want!" Seeing Xia Ruo in a daze, Lin Long immediately shouted at Xia Ruo sternly.

"Yes."

Natsuruo didn't directly use the system to learn the breath of water at first, but wanted to try it himself first to see how far he could do it and how it compares to Tanjiro.

Soon, Xia Ruo's breathing began to change.

During this period, Lin Long began to instruct Xia Ruo's breathing, corrected some of Xia Ruo's mistakes, and asked Xia Ruo to use some special standing postures to find the feeling of breathing.

Under such circumstances, after a few hours, Xia Ruo finally found some feelings.

Of course, it's just a little bit of feeling, and if you want to really learn to master it, and then apply it to actual combat, it's actually a long way off.

Lin Long has been paying attention to Xia Ruo's breathing rate on the side.

When Xia Ruo vaguely found the feeling, Lin Long also found it for the first time, and after noticing this, Lin Long nodded slowly, he was very satisfied with Xia Ruo's progress.

is worthy of being a genius introduced by the lord, not only is his physical fitness far beyond ordinary people, but even his learning ability is very strong, and he found the feeling of breathing in just one day.

If you continue like this, if you do it soon, you will be able to use Water Breath proficiently within three months.

Proficient in using the breathing method in three months, he is already a relatively powerful genius, at least Lin Long has instructed so many disciples, and there has never been one who can do this so quickly.

"Your progress is fast, if you keep it like this, you can learn to breathe water in three months, and if you work harder, it is possible to shorten it to two months," Lin Long told Xia Ruo about it.

"Does it take three months?"

Xia Ruo lowered his head and said to himself, three months is still a bit too long for him.

It is indeed a freak who sets the standard too high, and it is almost impossible to break the record of touching the sword for two months.

If Tanjiro is used as a standard, Xia Ruo's progress is actually very fast.

Tanjiro, as the protagonist, has both hard work and talent, but it still took a year of learning to learn Rintaki's breathing method and all sword styles, and then it took another year to integrate the breathing method and split the boulder.

"Don't be greedy for speed, being down-to-earth is the most stable way to improve your strength, and real combat skills take time to polish," Mr. Lin Long seemed to see through Xia Ruo's thoughts, and couldn't help but remind.

"I know, if you want to hurry, you can't do it," Xia Ruo responded as his breathing returned to normal.

At this time, it was almost three or four o'clock in the morning, and it was almost dawn.

"Let's get here here today, the test is all done, let's go back first, I'll arrange a place for you to live, you can rest first, go back and study the use of the breathing method," Mr. Lin Long said to Xia Ruo.

"Yes."

Xia Ruo followed Mr. Lin Long back to his hut.

At this time, Xia Ruo saw that Tanjiro had just come back, and it seemed that he had just finished training, and he looked very embarrassed, and for Tanjiro, a training maniac, it was normal to train for such a time.

Looking at Tanjiro, Natsuruo greeted him with a smile.

"Hello, my name is Xia Ruo."

"My name is Tanjiro, hello, we will live together in the future," Tanjiro was very tired, but he also responded to Xia Ruo with a smile, and he also knew that the one in front of him called Xia Ruo should also practice with him in the future.

"Well, please take care of me," Xia Ruo responded with a smile.

Sniff ~ sniff ~

Tanjiro's nose was sharp, he hadn't noticed it before, but now that he was very close, he smelled a very strange smell from this person named Natsuruka.

It was a smell that had never been smelled before, it was very special and a little unsettling.

It's not that he's uneasy about that person, but that there seems to be an unsettling power in his body, Tanjiro silently remembered this taste, and didn't say anything more, he was too tired and needed to rest.

Xia Ruo followed Mr. Lin Long into his cabin.

After that, after Mr. Lin Long arranged a room for Xia Ruo, Xia Ruo lay in his room and prepared to sleep, and it was true that he was a little tired after such a long journey, and he never rested in between, that is, he had good physical fitness and could persevere.

At night, Xia Ruo exchanged his reputation for the breath of water.

Something that can be solved overnight, there is no need to drag it out for three months.

……

Early the next morning.

After Xia Ruo woke up, he directly found Mr. Lin Long, Tanjiro has now entered the stage of splitting stones, so he is cultivating alone, and Mr. Lin Long is now only guiding Xia Ruo alone.

Appearing again, Xia Ruo's feeling was no longer the same as yesterday.

Mr. Lin Long also noticed this, he also smelled a different smell from Xia Ruo's body, and in one night, it seemed that something had really changed.

"Let's continue yesterday's practice and find the rhythm of breathing," Mr. Lin Long and Xia Ruo instructed.

"Okay."

Breathe and become a little different.

"All Concentration, Water Breath!"

Soon, a large amount of oxygen entered Xia Ruo's cells, and at that moment, Xia Ruo sensed that his physical fitness instantly improved a lot, almost a large increase in all aspects.

Mr. Rin Taki also noticed Xia Ruo's breath, which was the full breath of water.

"Succeeded? How is it possible, it was only ...... yesterday How can it be! ”

Mr. Rinlong's voice became a little shocked, and he even said how could it be two, but fortunately he was wearing a tengu mask, which covered his shocked expression, he had never heard of someone who could learn the breathing method in one day.

He had never heard of such a thing.

"How the hell did you do that?" It took five or six seconds for Mr. Lin Long to suppress the shock in his heart and asked Xia Ruo.

"I tried a few more times last night, and then I learned it, maybe I have a high compatibility with the Water Breath," Xia Ruo's face looked calm, without showing any proud look.

"Tried a few times......"

Lin Long was silent, if others told him that someone had mastered the breathing method in one night, he would not believe it, but the thing appeared in front of him, and he had to believe it.

Is this the realm of genius beyond mortals?

Lin Long also turned over the records of the ghost killing team, and remembered that there was a record about the deeds of the Initial Breath Swordsman, and among the former Initial Breath Swordsmen, there were swordsmen with outstanding talents.

How strong the swordsman who breathed at the beginning, Lin Long didn't know, but what he could know was that the rumors and some deeds that had been handed down in it were unacceptable to normal people.

For example, there is a rumor that a swordsman can kill a swordsman who has been famous for many years in seconds when he is young, and that kind of talent, once Lin Long would feel that it was a little exaggerated, but now that he sees Xia Ruo, he seems to understand a little.

There are areas that mortals cannot touch or imagine.

Lin Long took a deep breath and looked at Xia Ruo, at this moment, he had higher expectations for Xia Ruo.

Today's ghost killing team, rock pillar, Xia Zhu, and now there is another Xia Ruo, it is estimated that this era will become the peak era of the ghost killing team, perhaps, the thousand-year-old hatred between humans and ghosts can usher in the end of this era.

"Next, I'll give you all ten forms of Water Breathing, you can see it."

"Hmm."

Xia Ruo nodded.

After that, Mr. Lin Long demonstrated the ten forms of water breath to Xia Ruo, and at the same time, Xia Ruo remembered all of them in his heart.

"How much do you remember?" Lin Long asked Xia Ruo, in fact, he could have demonstrated one type at a time, but he changed his mind during the demonstration and demonstrated all the sword styles to Xia Ruo.

"Remember them all, Mr. Rinlong," Xia Ruo replied calmly.

At this time, the system beep appears again.

[Ding, you can directly learn the breath of water, the type of one ~ the type of ten, the prestige consumed: 300 points. 】

Xia Ruo: "......"

For sword skills, which seem to be very solid and reasonable, the prestige consumed by systematic learning is even less, to be honest, 300 prestige points, Xia Ruo really didn't pay attention to it.

"Learn!"

Soon, all the moves of the Water Breath were loaded into Xia Ruo's mind, and even Xia Ruo felt that he could easily perform them, after all, after learning the system, he would directly master it.

"Show me what you just learned."

"Yes."

Xia Ruo took out his own wooden knife from his waist, and then in front of Mr. Lin Long, he cast ten forms of water breathing.

"Breath of Water, One Shape, Water Slash!"

……

……

"The breath of water, the shape of ten, life and flow!"

All the moves were used smoothly by Xia Ruo, and he seemed very proficient, and Xia Ruo also noticed that when he cast the sword style, there would be a water splash effect on his sword.

Although this kind of splash is a special effect in the animation, and there is not much actual attack ability, and the attack mainly relies on the blade, but in the world of the animation, when the sword style is cast, this special effect really appears.

With a single slash, the water flowing in the air accompanied his sword style, and the surrounding water droplets flew around.

Not to mention anything else, handsome is really handsome.

Even Xia Ruo felt that the system charged 300 prestige points, but it was still collected for the sake of the sword style special effects.

"I've learned it again, and it's a complete mastery."

Looking at this scene, Mr. Lin Long on the side really had nothing to say, and he now wanted to reply to the lord.

"Lord, what kind of monster did you send me?"

However, fighting with Onimai Tsuji is not miserable, maybe it really takes a monster to defeat a monster.

"Next, concentrate on breathing, train all day, and I'll prepare a gourd for you," Lin Long didn't know how long he could guide this monster now.

It is estimated that within ten days, this guy will be able to leave the school.

……

Night.

When Tanjiro returned from his practice, he noticed that something was wrong with the atmosphere in the room, and he smelled a strange smell from Mr. Rintaki, like the smell of being hit.

"Did something happen today?" Tanjiro asked Mr. Rintaki.

"It's nothing, Tanjiro, let's rest when you come back," Rin Taki glanced at Tanjiro and sighed.

Alas~

"Huh?"

Tanjiro didn't understand why Mr. Rintaki was sighing at himself, he was just cultivating today, and he didn't do anything else.

However, he could still guess that this atmosphere should be related to Xia Ruo, and when he glanced at Xia Ruo, he found that Xia Ruo's expression was relaxed, and nothing seemed to have happened.

Odd?

Forget it, Tanjiro doesn't want to think about anything else.

He entered the bottleneck period a year ago, and now he has worked hard, practicing day and night for another year, and with the help of the rabbit, slowly, he has felt that he has really become stronger.

Perhaps, the time to split the stone is not far off.

You beans, wait for me, wait for my brother to save you when he becomes stronger!

Thinking that his sister was still unconscious, Tanjiro's heart became more determined.
