Ninja school teacher, I can become stronger by teaching...

If Obito had something else to say, he would have told him about how Obito almost got hurt by carelessness, but what Obito said this time was mostly true.

I have a headache and diarrhea, which prevents me from writing. I will update less today, but there will be another chapter later.

Chapter 206: Start practicing

"Every new level of breathing technique brings about a qualitative change. The next level of mastering the use of fully concentrated breathing is to breathe incessantly, allowing your body to maintain a state of fully concentrated breathing every minute and every second."

Mu Yue began to practice breathing techniques with Shisui and Obito.

In the world of Demon Slayer, mastering the art of constant practice is the foundation for becoming a pillar and is a crucial training that can greatly enhance physical abilities.

The Hokage-like breathing method of Changzhong is equally important. If you can master Changzhong, the ability to accelerate the change of properties will become permanent. In other words, your property change will be stronger than normal, and your physical abilities will also be greatly enhanced.

Mu Yue's growing strength has a lot to do with the constant practice of Breathing of Rock.

"Ah? Maintaining full concentration breathing all day long? How can I do that? I can't do it even if I die of exhaustion." Obito thought about his own state when he used the full concentration breathing method, and it was a little hard to imagine.

Shishui looked at Mu Yue with a puzzled expression. How could one practice Full Concentration Breathing as a burst of power to last 24 hours?

"It's not as difficult as you think. You can do it with more practice." Mu Yue said with a smile. With Obito's compatibility with the Breathing of Fire, there would be no problem at all.

"But I can only maintain my breathing for four minutes with full concentration." Obito felt that Mu Yue's more practice might mean practicing for more than ten years.

"The breathing method does not require you to be in extreme breathing all the time, but to be relatively concentrated. Assuming that your extreme breathing can increase your strength by 100, you only need to do 70 or 80 in normal practice." Mu Yue said.

"So that's how it is, but that wouldn't be enough chakra, right?" Obito understood a little bit, and then continued to ask, the Hokage's native breathing method can only achieve the maximum effect with the addition of chakra.

"When there is no combat, you can choose not to use chakra, or maintain a small amount of chakra output. There will be special training for this." Mu Yue answered.

The best thing is of course to add chakra, which will have a better enhancement effect and no need to make adjustments during battle. After all, the disciples now have limited chakra, so they can only practice the beggar version of the youth version first.

After Mu Yue explained it this way, Shisui understood the significance of Changzhong, which was essentially to increase the upper limit of their breathing techniques.

If they can maintain a breathing method with an output of 80 all day, then their real breathing limit will definitely no longer be 100, it may be several times higher.

"First, everyone enters a state of fully concentrated breathing without using chakra." After finishing the explanation, Mu Yue began to lead the students in formal Changzhong training.

Obito and Shisui both entered a state of full concentration breathing as Mu Yue said.

Snapped!

Obito's head was hit, and Mu Yue withdrew his hand and said, "Don't use chakra."

Mu Yue clearly saw through his Byakugan that Obito was consuming chakra and using breathing techniques.

"Hehe, I'm used to it, so I just use it subconsciously." Obito scratched his head a little embarrassedly, as he made a mistake at the first step.

Generally, when you use full-concentration breathing, you aim to defeat the enemy in one breath, so naturally you use the strongest you can.

Boom!

At this moment, there was a sudden loud noise. Obito and Shisui looked over and saw that Mu Yueying's clone had brought several stones of different sizes and placed them here. The small ones were almost as tall as Obito, and the large ones were more than three meters high.

"Come on, start practicing. Hold these stones and do squats until you can't maintain full concentration on your breathing." Mu Yue said with a smile, pointing to the huge rock next to him.

"Is it this difficult from the start?" Obito was a little dumbfounded. He remembered that when he first started practicing the breathing method, he just inhaled and exhaled on the spot. The intensity of this practice was visible to the naked eye.

Shisui walked forward calmly and tried them one by one. Finally, he picked a stone that was almost as tall as Obito, lifted it up and started squatting.

The stone looks heavy, but this is a state of full concentration and breathing, and even without the addition of chakra, it can bring considerable improvement to physical abilities.

Seeing Shisui start practicing directly, Obito quickly walked forward and picked up a stone that was larger than the one Shisui picked up and started practicing.

It's not that he's competitive and has to choose one that's bigger than Shisui's, but the one Shisui took was the smallest.

However, when he lifted the stone and did a squat, it was not as heavy as Obito had imagined.

Of course, this was just the beginning. As time passed, after five minutes, Obito felt a little tired, and he began to find it difficult to maintain full concentration on his breathing.

Maintaining full concentration on breathing is a strenuous task in itself. It not only consumes physical energy, but also requires a high level of mental concentration.

In the end, Obito put down the stone in five and a half minutes, while Shisui took half a minute less than Obito and put down the stone in five minutes.

"You maintained full concentration on your breathing for five and a half minutes. You see, you can actually hold on longer than you thought." Mu Yue praised with a smile.

Obito's fatigue was instantly swept away and he smiled foolishly. Mu Yue always gave positive feedback in time.

"Shisui, you are also very good. You are younger and will suffer some disadvantages." Mu Yue touched Shisui's hair and comforted him.

A faint smile appeared on Shisui's face.

Mu Yue did not give the two of them time to rest. Three minutes later, Mu Yue asked them to enter the breathing method state again and exert all the power of the breathing method that they could exert.

"Next is running, and you can't stop until you can't maintain your breathing method anymore." Mu Yue said.

The purpose of regular training is actually to make the body remember the breathing method so that it can maintain full and concentrated breathing throughout the day, and even consciously practice full and concentrated breathing while sleeping.

Therefore, the training intensity in Changzhong is extremely high, which is completely different from the level of practice in the entry-level stage.

In other words, Mu Yue has a secret medicine for training, otherwise he might have slowed down his training. The intensity is even higher than that of Might Guy before.

By the end of the training, Obito's legs were weak, his head was dizzy, and he could hardly tell east from west. He felt like his body no longer belonged to him, as if his soul could float up to the sky at any time.

"I'm so tired." Obito sighed sincerely.

He felt that his previous training was weak compared to today's. He didn't know how many times he had used full-concentration breathing. He couldn't even tell whether it was normal breathing or full-concentration breathing.

A series of basic training such as running, weighted squats, weighted push-ups, etc., plus the need to maintain full concentration and breathing conditions, instantly become extremely tiring.

Even Shisui couldn't maintain a calm expression, exhaustion written all over his face.

Mu Yue smiled faintly and said nothing. This was nothing, just some basic training. There would be more intensive training later.

That's it for today. I feel like I need to adjust my work and rest schedule. It's not good to sleep at 3 o'clock every day.

Chapter 207 Kakashi's Heart Knot (5k)

"Yesterday's mission was really dangerous. Thanks to your support, Long Xian, otherwise I would have been in danger."

"Haha, we are companions. I'm not a guy like Kakashi who would ignore his teammates for the sake of a mission."

"Speaking of Kakashi, I heard some time ago that his team suffered heavy losses during the mission. Only the guidance jounin and himself survived. How miserable."

"It's really unfortunate to be on the same team with that guy. Fortunately, we left early, otherwise the same thing might have happened to our team."

After the training, Kakashi dragged his tired body home and met his former teammate on the way and was chatting with him.

Hearing the conversation between the two, Kakashi's thoughts on breathing techniques were suddenly interrupted.

Kakashi did not deliberately hide his whereabouts. The two former teammates noticed Kakashi just walking over and closed their mouths instantly.

"Ahem, Kakashi, good evening." The former teammate didn't know whether Kakashi heard it or not, but Kakashi didn't say anything, just pretended not to hear it and greeted him.

"Well, good evening," Kakashi replied with a deadpan nod, then continued walking towards home.

"It's so embarrassing. I don't know if he heard it."

"It doesn't matter whether he heard it or not. He probably doesn't have a good impression of us anyway."

Kakashi, who had good hearing, could still hear some subtle conversations even if he walked away for a distance, but he no longer had the mind to pay attention to it.

Kakashi was not angry because his two former teammates talked about him behind his back. If he was angry about this little talk, he would have been furious when his father committed suicide, because he would have felt strange looks wherever he went.

And they were indeed right. For Kakashi, the mission had the highest priority. Even if they were injured during the mission, Kakashi still put the mission first.

Except for the beginning, during the time when he became Mu Yue's disciple, Kakashi rarely thought about what it meant to be a qualified ninja, and whether a ninja should put the mission first.

Because Mu Yue's training intensity is at its maximum, he is either learning advanced ninjutsu like Pseudo Dark Purple Lightning or secret and forbidden techniques like Thunder Breathing and Armament Haki. Under such high-intensity training, it is difficult for him to have the energy to think about other things.

And there was also Obito in the team who was really pulling his mood, forcing Kakashi to use the rest of his energy to fight against Obito.

The words of his two former teammates made Kakashi once again fall into thinking about the mission, ninja and teammates.

"The reason why my father is blamed by everyone is because he failed the mission, so the ninja who can complete the mission is a qualified ninja." Kakashi thought to himself.

Then Kakashi shook his head again. He thought of Mu Yue's words. Bai Fang followed his own ninja way and was not a failed ninja.

Although he had not known Mu Yue for a long time, Kakashi admired Mu Yue very much. It was not only because Mu Yue was very strong, but also because Mu Yue was excellent in all aspects of being a teacher, which was different from all the teachers he had met before.

So Kakashi was willing to listen to and believe what Mu Yue said.

A hint of confusion appeared in Kakashi's eyes. On one side was the established fact that his father was blamed for the failure of the mission and eventually committed suicide. On the other side was the recognition from his admired teacher, telling him that White Fang was actually a ninja worthy of respect.

Kakashi thought and thought, ate dinner, and thought until eleven o'clock in the evening, but still couldn't come up with anything.

Lying in bed, Kakashi couldn't fall asleep for a long time. Even though he was very sleepy, he wanted to sleep, but as soon as he closed his eyes, he couldn't help but think about those things, which made it impossible to fall asleep.

In the end, Kakashi didn't know when he fell asleep, but when he woke up and saw the big sun outside, Kakashi knew one thing: he was late.

Kakashi quickly finished washing up, then grabbed some edible food and stuffed it into his mouth before rushing to the southern forest.

When Kakashi arrived, other disciples were already practicing. Obito and Shisui were running with full concentration breathing and were covered in sweat. Metkai was scratching his head and practicing the changes in Yin Escape properties. There was an injured fish next to Nohara Lin. There are also broken trees.

Obito, who was running, happened to pass by Kakashi. Seeing Kakashi who was late, Obito wiped away the tiredness on his face and laughed out loud:

"Hey, isn't this Kakashi? Why are you two and a half hours late today?"

"Did you also go to help the old man?"

After saying this, Obito instantly felt refreshed, and his body didn't seem so tired anymore.

In the past, he was always scolded by Kakashi for being late, but this time it was finally his turn.

"I just slept late." Kakashi explained expressionlessly, then walked over to Mu Yue.

"Tsk, you're still so arrogant even though you're late." Obito muttered and continued practicing.

"Mr. Muyue, I'm sorry." Kakashi apologized, "I didn't sleep well last night, so I got up late today."

"It's okay. There's nothing wrong with being late occasionally. After all, accidents always happen. Let's start practicing." Mu Yue said with a smile.

Kakashi nodded, and then began to practice Thunder Breathing under Mu Yue's guidance.

I don’t know if it’s because I didn’t sleep well last night or what, but Kakashi couldn’t feel the rhythm when practicing breathing techniques today. After finishing the practice in the morning, he didn’t feel any progress at all. This was even more so when he practiced Armament Haki in the afternoon.

In the morning, he could explain it by being two and a half hours late and not having enough time to practice, but in the afternoon, he really didn't know what he was practicing.

Normally, when Mu Yue explained and demonstrated, he could automatically rehearse it in his mind, but that didn't happen today.

Although Mu Yue didn't know what happened to Kakashi, he noticed something was wrong from Kakashi's performance.

"Kakashi, your mind is in turmoil," Mu Yue said.

Armament Haki is a Yin escape technique, which is related to mental strength. If one's mental state is not good, the result will be half the effort and twice the result.

"I'm sorry, Teacher Mu Yue, I'm not in a good condition today. I will try to adjust myself tomorrow." Kakashi said apologetically.

Mu Yue taught him so seriously, but he couldn't even concentrate on studying. Kakashi felt a little guilty.

"Do your best and remember to believe in yourself." Mu Yue said with a warm smile.

"Thank you." Feeling the warmth from Mu Yue, Kakashi felt a little relieved.

Having been late during the day and having made no progress in his training, Kakashi tried to make up for it by doing extra training at night, practicing breathing techniques in his own yard.

However, the training was still not going smoothly, and Kakashi could not find that feeling.

At ten o'clock in the evening, Kakashi took a shower and went to bed.

As soon as he lay down on the bed, Kakashi subconsciously recalled the accusations his father had suffered in the past and his teammates' disapproval of him. Then he remembered Obito's words and Mu Yue's words.

His mind was filled with mixed thoughts. Sometimes he thought that a ninja must abide by the rules and complete the mission even if it means sacrificing his companions. Sometimes he thought that his companions were the most important and he had to protect their safety.

"Sleep, sleep..." Kakashi kept repeating the word sleep in his mind. He heard that this could be a way to cure insomnia. He could give himself a suggestion and then feel sleepy.

I don’t know if the method didn’t work or if it was Kakashi’s own fault, but he still couldn’t fall asleep. At this time, Kakashi looked at the time and it was already two o’clock in the morning.

With a slight sigh, Kakashi tried to sleep again.

"late……"

When Kakashi woke up the next day, he saw the scorching sun outside and knew that he was late again.

He quickly packed up and headed to the Southern Forest to begin his training.

"Kakashi, you are two and a half hours late again. Did you stay up late to practice until the early morning?" Obito looked at Kakashi suspiciously.

He suspected that Kakashi was secretly trying to trick him. How could someone like Kakashi be late twice in a row, and both times for such a long time?

"No." Kakashi answered concisely with an expressionless face, then walked up to Mu Yue and began to explain.

"Teacher Mu Yue, I'm sorry, I couldn't sleep again last night." Kakashi explained.

Mu Yue asked with concern: "Are you feeling well? Why did you suddenly suffer from insomnia?"
