Dream projection from Naruto

Chapter 27 Abdominal breathing, breakthrough imminent [23]

In September, the weather is still a little hot.

Nobuhiko still woke up early.

“It’s so hot~ I really want air conditioning”

After taking a shower, the sultry weather made Nobuhiko sigh.

Obviously, the technology of Naruto World has even invented refrigerators, TVs, and computers.

There is no air conditioner, is this beaver?
Although chakra can enhance the physique of ninjas, making them more heat-resistant and colder than ordinary people, the effect is not very significant.

Just like in the previous life, if there is no heating in winter, you will not be able to withstand the cold because of your uprightness.

There is no summer vacation at Ninja School. Only after the end of a school year will there be a New Year's holiday for nearly a month.

Normally, Nobuhiko would come back to take a shower after the morning exercise.

And today he wasn't going to go out.

【Chakra Refining Technique LV7】

【Spirit: 1.99】

【Breath of Thunder LV6】

The spiritual attributes that have long been stuck in a bottleneck seem to be showing signs of breaking through.

So in the past few days, Nobuhiko has spent a lot of time every day practicing breathing and refining chakra.

The level of chakra refining has been raised by another level, and Nobuhiko's chakra refining speed is nearly one-third faster than before.

And the progress of the practice of breathing method is beyond Nobuhiko's expectations, and has reached level 6.

It was originally scheduled to take a year or two to upgrade to level 7, and now it seems that there is even a chance to achieve this goal before reaching the second year.

Chakra is composed of spiritual energy and physical energy, and every time a large amount of chakra is consumed, when it is refined again, the upper limit of chakra will increase slightly.

Especially after Nobuhiko obtained Kaguya Chakra, this feeling became more and more obvious.

On the other hand, cultivating the thunder breathing technique will also consume stamina and chakra constantly.

The increase of physical and mental attributes has a mutually reinforcing effect.

Under the high-intensity practice of Nobuhiko, I feel that I am about to break through the bottleneck.

Anyway, with the passage of time, Kaguya's chakra will gradually merge with his body little by little, and will always break through.

It's just that Nobuhiko wants to become stronger as soon as possible.

Because the progress of [Secondary Consciousness LV3] has been stagnant for a while.

The higher the skill level, the greater the increase in spiritual power growth.

And after reaching LV4, Nobuhiko will be able to have one more [Secondary Consciousness]

That way, his learning rate can be doubled again.

Now he can study two different disciplines at the same time and think about two unrelated things at the same time.

Adding another [Secondary Consciousness], the benefits to him are obvious.

After all, he was not a medical student before crossing, and could only learn medical ninjutsu from scratch.

Fortunately, with the help of magical Chakra, strong mental power and a [Secondary Consciousness], his learning progress is very fast.

This is the result that Nobuhiko has hidden. After all, he is mainly studying at Konoha Hospital, and he doesn't want to show his talent too early in front of others.

After taking a shower and putting on his clothes, Nobuhiko sat cross-legged on the bed and began to practice the breath of thunder.

At the beginning, he took continuous deep breaths and quickly entered the state.

"hu~hu~"

Nobuhiko's lower abdomen rose and fell slightly, and the interval gradually became longer.

His breathing was long and slow as his breathing rhythm adjusted.

Just like abdominal breathing.

Normal people generally use the chest breathing method. When breathing, only the ribs move up and down and the chest slightly expands. The time required for one breath is about 3 to 5 seconds.

A complete breathing movement consists of inhalation and exhalation.

Under normal circumstances, the breathing rhythm and depth are relatively regular. Generally, the respiratory rate of adults is between 12-20 times per minute, and the respiratory rate of children is about 30 times per minute.

Abdominal breathing is inhaling through the nose and exhaling through the mouth.

One breath and one breath are controlled for about 15 seconds.

即深吸气（鼓起肚子）3～5秒，屏息1秒，然后慢呼气（回缩肚子）3—5秒，屏息1秒。

Using abdominal breathing can significantly increase lung capacity and increase cardiopulmonary function.

It's just that ordinary people will experience difficulty breathing and chest tightness due to hypoxia if they do not master the skills.

The prerequisite for the practice of Thunder Breathing is to master the abdominal breathing method.

And the requirements are much more difficult than normal abdominal breathing.

Nobuhiko's breathing rate when using the breathing method in a static state is once every 20 seconds and three times a minute.

And if he is moving at high speed and in fierce battles, he can't maintain this frequency, so he can increase it to 1 breaths per minute.

As for the full concentration breathing method, he estimates that he can only breathe 1 times a minute, or even 2 time.

Inhalation is more conducive to concentration and explosion of power than exhalation.

For a long time, he could not reach this level.

Because it is also related to the development of the body.

Some people are born with strong heart and lung function and large lung capacity. This is talent.

"Whoo~"

Nobuhiko took a deep breath again, stopped the practice of breathing, and returned to normal abdominal breathing.

Every time I practice the breathing method, I have to stop when I feel a little chest tightness.

"It's really tiring! After more than an hour of static practice, I couldn't hold on anymore."

Nobuhiko wiped the sweat from his forehead, picked up a book from the room, walked towards the kitchen, and started making breakfast.

After making breakfast, he sits on the sofa reading while eating, which is the most relaxing time of his day.

After eating, Nobuhiko began to refine chakra again.

"There is still no breakthrough, it seems that we need to work harder!"

After stopping chakra refining, Nobuhiko still showed no signs of breaking through, and the data on the panel did not change much.

"Oops! It looks like I'm on duty today!"

Nobuhiko looked at the clock on the wall, it was already [-]:[-], and then he remembered that it was his turn to clean up today.

He hurried back to the room, put on his schoolbag, put on goggles, and ran all the way towards the ninja school.

By the time he arrived at the class, Kakashi and another boy, Kota Morikawa, had almost finished sweeping the ground.

The class starts at 8 o'clock. Students on duty usually arrive at [-] o'clock. Nobuyan is more than half an hour late.

Due to cleaning, the students who came to the class early were all outside.

"Nobuhiko! It's too slow! Kakashi and I are about to finish sweeping the floor for you!" Xiaota couldn't help complaining when she saw Nobuhiko who was late.

Nobuhiko looked at Kakashi with a calm expression, and Kota with one hand on his hips, and said with a smile:

"I'm sorry, I got up late today, I'll take out the rubbish, and I'll invite you to drink soda during the lunch break!"

"You're acquainted." Xiaotai said with a smile: "I want to drink orange flavored."

"No problem, I'll help you put down the stools." Nobuhiko nodded with a smile, then started from the back and took down the upside-down stools one by one on the finished table.

When Nobuhiko came to the front row, Kakashi and Kota also came to help after sweeping the floor.

When she was in the first row on the left, Kota suddenly came to Nobuhiko's side, pointed to Hyuga Mio's seat, and asked in a low voice:

"Nobuhiko, do you like Mio-san?"

"Huh? Why do you ask this suddenly?" Nobuhiko was slightly taken aback.

Xiaota suddenly looked at Nobuhiko with some vigilance, "You don't like Maki-san, do you?!"

"Of course not!" Xin Yan shook his head, if he didn't practice well now and fall in love, wouldn't he be a fool.

"That's good! No! You don't like a cute and gentle girl like Maki-san?!"

Xiaotai's expression was relieved at first, and then he seemed to be dissatisfied with Nobuhiko's attitude.

Of course, compared to No.1 Kakashi, Nobuhiko, who has a gentle personality and a very high appearance, is his biggest opponent.

Now that such a strong competitor is missing, he is relieved.
