After eating the Heat-Heat Fruit, my Fire Style is invincible

"Then you have to complete the full concentration breathing of the fire breathing."

The so-called full concentration breathing is still the concept of Demon Slayer.

That is to maintain the state of breathing method all day long, which will test Huang Huo's lung capacity.

Therefore, training lung capacity is an important step.

Huang Huo thinks it is not difficult. You know, the fire escape ninja uses the mouth to release fire escape, which is also a test of lung capacity.

The fire escape ninja with more lung capacity can maintain the fire escape ninjutsu for a longer time.

It's just that there is no special training like in Demon Slayer.

"Blow up the gourd? Prepare a batch of gourds first."

The cautious Huang Huo ordered the shadow clone to buy a batch of gourds that were big enough after school and started training.

He blew up a gourd in just one day.

Then he blew up 10 gourds in a row.

"That's it, it's not that difficult!"

At this moment, Huang Huo smiled and said it was easy.

Then he started to practice breathing with full concentration.

"Fire Breathing! Let me see how long I can hold on."

Huang Huo entered the state of Fire Breathing, and the fire attribute chakra immediately became active.

The temperature of the whole body gradually rose. After an hour, it felt like the lungs were about to explode. When it reached the limit, it exited the Fire Breathing mode.

"One hour? It's already pretty good that I was able to maintain the fire breathing mode for an hour for the first time."

"Then, continue training."

When his lungs calmed down, Huang Huo entered the fire breathing mode again. After a week of training, he reached the two-hour limit.

"I thought it wouldn't be hard to concentrate on breathing, but I still haven't finished it after more than a week."

"What is the reason? Am I not practicing hard enough? Or is my understanding of the Breath of Fire too low?"

Now Uchiha Huang Huo has completely lost the sense of ease that comes with blowing up the gourd, and is seriously thinking about how to quickly complete the practice of Full Concentration Breathing. After careful consideration, Huang Huo finally found the reason for the slow progress of Full Concentration Breathing.

"The reason is that my physical fitness is too low. Even though the people in the ninja world are generally in better shape than those in the past, I am still very weak."

"With the speed of strengthening the body with the Breath of Fire, it would only take two or three years to reach the level of fully concentrated breathing."

"So should we wait two or three years?"

Huang Huo fell into deep thought, thinking, is there no other way?

It's okay to wait patiently, it will only take three years at most.

During this period, maybe I will have an epiphany and complete the full concentration breathing ahead of time.

"Hmm? Maybe we don't have to wait so long, maybe the power of the Heat-Hot Fruit can still work."

His eyes suddenly widened, and his face was thoughtful, because Huanghuo thought of the power of the Heat-Hot Fruit.

He thought that when breathing with full concentration, the lungs would be under great pressure, and the higher the pressure, the higher the temperature of the lungs would be. When it is so high that the human body can't bear it, it is Huanghuo's limit.

The increase in lung temperature means lung explosion.

However, with the power of the Heat-Hot Fruit, Huanghuo only needs to heat the lungs to the point where he can breathe with full concentration.

Then maintain full concentration breathing, and wait until his physical fitness is strengthened and his lungs are strengthened to a sufficient strength before canceling the power of the Heat-Hot Fruit.

"This is a new way to speed up the practice of full concentration breathing. You can give it a try."

Thinking of this, Uchiha Huanghuo's mind moved slightly, and the power of the Heat-Heat Fruit was released, and the lungs were heated to 39 degrees Celsius, and then entered the mode of fire breathing.

"Heating to 1000 degrees Celsius for 10 seconds, heating to 300 degrees Celsius for seven minutes, and heating to 39 degrees Celsius for even longer."

The fire breathing mode lasted for one hour, two hours, and then it reached its original limit.

It continued for three hours, four hours, and at 10 hours, the physical strength was exhausted and it exited the fire breathing mode.

"Well, let's try the breathing of fire without heating."

After recovering his strength, Huang Huo did not use the power of the Heat-Heat Fruit to heat his lungs. This time the limit time was two hours and ten minutes.

"Well, my guess is correct. Using the power of the Heat-Heat Fruit can speed up training."

In this way, in a month, Uchiha Huanghuo finally completed the full concentration of fire breathing.

He can breathe fire all day long. At the same time, he can sense his own subtle conditions and can heal minor bleeding.

Huanghuo also felt that his chakra control was strengthened a lot.

"Breath of Fire, Full Concentration, Form One, Round Dance!"

The breath was flaming, and the blade carried high temperature flames and slashed forward fiercely.

""Fire Breathing, full concentration, Uchiha Sword Leaping Flame!"

Another terrifying flame sword slash.

These days, Huang Huo not only concentrated on completing the full concentration breathing, but also reproduced the Sun Breathing moves in the Demon Slayer World in his mind. It is very appropriate to use the Fire Breathing to release these moves.

"Moves that use full concentration breathing are 10 times more powerful than normal moves."

"Such a terrifying enhanced move can be used as a regular move, it's really terrifying."

Full concentration breathing also has a bonus effect on the fire chakra mode

"Next, continue to strengthen the full concentration breathing and swordsmanship training."

Not only the swordsmanship moves are important, the foundation of swordsmanship is also important.

After just four months, Uchiha Huanghuo's fire breathing has become an instinct, and his physical fitness and chakra have been greatly enhanced.

Just talking about the chakra amount, he has reached 1 card.

If Kakashi's adult chakra amount is 1 card, and 100 cards is the chakra amount of Uzumaki Naruto, it can be called 1 Naruto. If the fire breathing is practiced like this, it is only a matter of time to achieve the chakra amount of 1 Naruto.

At this moment, the elite class of Konoha Ninja School was talking about it.

"Have you heard? Our current head teacher, Hatake Kakashi, has applied for early graduation"

"I'm about to graduate after only a few months of school? Is this true?"

"Really, I have to say that Chief Hatake Kakashi is indeed a genius, and ordinary people like me are far behind him."

"I am still not proficient in the Three Body Technique, while others have already graduated. Why is there such a big gap between people?"

The whole class was full of praise and envy for Hatake Kakashi.

Uchiha Obito on the side gritted his teeth and whispered,"Damn Kakashi, he only knows how to show off!"

Hearing Nohara Rin say that Kakashi was amazing, he was even more envious and jealous, and he thought to himself that he would definitely make Kakashi pay in the future.
