After hearing what Hatake Kakashi said, Mizuki thought for a while, and then said: "In terms of absolute value, this technique does have immeasurable potential, and it is not an exaggeration to praise it. But Kakashi, have you ever thought about it? The value of each ninjutsu is also linked to its learning difficulty. How many people in Konoha Village do you think can learn it?"

"There shouldn't be many people." Kakashi thought about it and had to answer helplessly. "Even for me, it might not be easy to complete this technique."

With Kakashi's reputation as Konoha's technician, he himself admitted that it was difficult to learn, so it would be even more difficult for others to get started.

"And, Kakashi, this technique is not without substitutes. The biggest feature of the Breath Retention Technique is the huge amount of chakra reserves. But there are so many ways to replenish chakra in the ninja world. I'm sure you can list a lot of them, right?"

The Yin seals that are somewhat similar to the effect of the Breathing Technique, various secret techniques and bloodline limits that absorb chakra, not to mention the stimulating secret techniques with amazing side effects, and various pills that replenish physical strength and chakra. The role of the Breathing Technique in the hands of ninjas like Haruno Sakura, Hatake Kakashi, and Mizuki is simply immeasurable. But for someone else, not to mention whether they can learn it or not, even if they can learn it, what can they do with so much chakra? Cast a few more Great Fireball Techniques? Is it meaningful? Only ninjas who need a huge amount of chakra to play their specialties will spend a lot of energy to learn this Breathing Technique.

Mizuki's question made Kakashi Hatake not know how to answer for a moment.

"Although I can't win the argument with you for now, Shuimu, your excuse is also untenable."

Hatake Kakashi is not someone who can be easily fooled. In fact, Mizuki also understands that what he said just now was just a change of subject and a specious argument. Mizuki realized a long time ago that this was the result of his cognitive differences from his previous life and his failure to fully adapt to the values ​​of the ninja world. The difference in his growing environment and education made Mizuki not realize how amazing the value of what he has learned is when he reaches a certain level and becomes a role model for others to look up to. If all these achievements are realized, it will be enough to support a small ninja village.

However, now an important part of it, the Breathing Technique, was taught to Haruno Sakura. At that time, Mizuki thought it was just a long-term investment and an academic study. Now it seems a bit inappropriate. It's not that it was wrong, but this behavior that was obviously not in line with the tradition of the ninja world was actually challenging the order of this world. It was not until later that Mizuki realized that there are three things in this world that are themes that never change: blood, inheritance and heroes.

The veins of the ninja world from ancient times to the present cannot escape these three constraints. The reason why this world is complicated is that there are indeed causes of unrest in the ninja world. It is also very simple to say that it is simple. The bloodline passed down from the Otsutsuki family is the main line of the ninja world, the inheritance of knowledge and power is the driving force of the development of the ninja world, and the legend of heroes is the history of this world.

Shuimu's behavior has nothing to do with right or wrong, and it doesn't matter how you look at it. Whether intentional or unintentional, breaking the rules is inappropriate. Even if Shuimu himself thinks it's okay to teach, it will still make people dislike it.

"Although I know now, if I make another choice, the result won't change much."

This difference in values ​​is reflected in different ways by each person. Shuimu will not make a choice that goes against his heart for such an insignificant thing. Moreover, even if someone dislikes him, after two or three years, the order will collapse, and who will care so much. As long as his strength is strong enough and he can withstand the pressure of others looking at him, what's the big deal if he is willful once or twice?

Seeing that Mizuki still looked indifferent, Hatake Kakashi was not too surprised.

"Mizuki, even though we haven't been together for long, I know your style pretty well. You may not take it to heart, and Sakura may be ignorant now, but what about in the future?"

Since Kakashi said so, Mizuki can't treat it as irrelevant. Indeed, Mizuki is not afraid, but it doesn't mean that he won't delay Haruno Sakura. With Mizuki's unique secret technique, does Haruno Sakura really have a chance to gain Tsunade's recognition? In fact, the situation of "bringing art to the master" is not much different from the stepmother's child.

"You have to understand, Kakashi, I can teach Sakura, there is no problem with that. I have the strength and confidence to do so, and I will not hinder Sakura's development and future. However, this would be a waste of her talent in medical ninjutsu. I can fool others, but don't you understand that I am a complete layman when it comes to medical skills?"

Mizuki paused, then said solemnly: "Besides, this also needs to take Sakura's wishes into consideration. You can give advice and convenience, but I think it's best not to arrange everything. The path of a ninja still needs to be chosen by yourself."

Sakura finally chooses to learn from Mizuki and become a combat ninja proficient in sealing techniques, or to become an apprentice of Tsunade and become a violent medical ninja. It is more appropriate to wait until Sakura makes a decision before arranging the next step.

Seeing that Hatake Kakashi was silent for a long time after listening to Mizuki's words, Mizuki knew that he had temporarily convinced him.

"Alas, your eloquence has made you feel wronged as a ninja." After a long time, Hatake Kakashi smiled bitterly and said, "I was indeed too impatient about this matter."

"What happened recently? What made you so anxious?"

"It's Sasuke." Kakashi said with a headache, "Recently, he has left the village for too many missions. Team 7 has too little discipline, and even rarely forms a team to do missions. But Naruto has Master Jiraiya to arrange things for him, so he doesn't need to worry too much. I'm now spending most of my energy on Sasuke, so naturally, Sakura has to make some arrangements, otherwise wouldn't it seem too partial?"

"That was said more than two months ago, you still remember it?" Before the Chunin Exam, Mizuki complained to Kakashi about something similar, but he didn't expect Kakashi to remember it.

"You have a point, but I didn't think enough about it. I didn't even consider Sakura's own will."

"You are too concerned, but don't underestimate your students. They will find their own way."

"I have been a team leader for so long, but I didn't expect that I am not as insightful as you."

"How long have you taught Sakura? How long have I taught her? Adding in the experience of the ninja school, you're far behind, Kakashi."

"That's right. If it weren't for the strong request from the Third Generation, I would not have taken on such a troublesome matter."

"Is it still useful to complain now?" In Mizuki's opinion, Uchiha Sasuke and Uzumaki Naruto were the most important reasons why Hatake Kakashi decided to teach Team 7. The last clan member of Uchiha Obito, who was once a companion and friend, and the son of the teacher, the Fourth Hokage, this reason was enough.

"Hey, Mizuki, what do you think I should do with Sasuke?" Kakashi asked, seeming a little confused.

"Handle? Kakashi, you're taking on too much responsibility. He will naturally find his own way. All we have to do now is to try our best to guide him."

"I'm just a little worried. Hatred is a beast that gnaws at the soul. If you're not careful, you'll become a pitiful creature whose soul has been lost in hatred."

Mizuki couldn't answer this question. Mizuki didn't want to talk to Kakashi about such a question that had no answer.

"Well, I'm almost there, so I'll go back first."

Having already completed a section of the route, Shuimu also wanted to go back and rest early.

"Well, thank you for your advice today."

"You're welcome. I'm a teacher too after all!"

…

After being blown by the cool breeze of the summer night, Shuimu, who had drunk a little wine, had actually become much more sober. When he returned home, he found that the lights in the room were still on.

"Is Xiaochun here?"

Shuimu pushed the door open and saw his fiancée waiting for him in the room.

"You're back?" Xiao Chun came forward and prepared to support Shuimu. "Why did you drink? You didn't like it, but you drank so much?"

"Don't worry, it's not much." Shuimu indicated that there was no need for support, then took off his coat and handed it to Xiaochun to hang up. Since they were at home and there were no outsiders around, it was okay to be casual.

"Xiaochun, have you had dinner?"

Mizuki asked as he walked into the bathroom and washed his face to sober up.

"I have already eaten."

"That's great. It would be best if you could come with me today. It would be a good opportunity for you to get acquainted with my friends."

"I already know those people, and isn't that a party to celebrate your promotion to jonin? You can just go."

"That's a shame. I invited them to the wedding, and it would be great if you were here."

"Well, it's okay." Xiao Chun smiled kindly, "I'm different from them. To celebrate your promotion, I have prepared a gift."

"Is this what you're doing at home? Let me see what it is?"

"Wait a moment." Xiao Chun took out a pair of full-finger gloves with a red and black metallic luster.

"This is a gift? Eh? This feeling..."

The material of the gloves was extremely strange, they looked to be metal, and they had a sense of déjà vu, yet they seemed to be different.

Then, Mizuki put it on and tried it. The chakra conduction was excellent and the flexibility was also quite good, without affecting the movement of his hand.

"What is this made of?" Shuimu asked curiously, "It's quite good stuff."

If we were to ask which part of Mizumu's body has been injured the most and most frequently in the past few months, it would undoubtedly be his hands.

"Playing with fire means getting burned" is a fact that every fire-style ninja has a deep understanding of. Whether in practice or in battle, the hands are closest to the source of fire and can get burned if not careful. Mizuki once suffered from this.
