If you ask Shuimu why he thinks so, it’s because he has been well educated.

When Uchiha Itachi invaded Konoha Village, the fake Jinchuriki clone he sent out used his body to block a blast of Amaterasu in order to protect Might Guy. The pain of burning his flesh and soul is still frightening to Mizuki when he thinks back to it now.

Few people can bear the pain of near-death when their shadow clones cannot disappear in time. After all, only a few people are willing to accept the pain and death of their bodies like Hidan.

Shuimu, who had suffered a great loss once, considered that in case the main body and the clone needed to fight together, when the clone was killed, the main body would suffer huge mental damage. If he couldn't react in time, wouldn't he be killed twice?

In order to prevent this from happening again, Shuimu had to take a preventive measure.

The only thing in my hand that has a mental defense function is the soul gathering array, but this sealing array is too large and complicated. Even if I keep improving it, I can't temporarily change the reality that this is not a combat skill.

As a last resort, I can only turn it into a small sealing technique while weakening some of its functions. Although the effect is greatly reduced, it is enough to calm the mental shock of the shadow clone. Naturally, this technique is also very effective in relieving the mental fatigue accumulated by the shadow clone during training. If you rest more afterwards, it will basically not interfere with your normal life.

"How do I use this?" Sakura unfolded the scroll and took a look. "Concentration Technique?"

This name is really confusing.

"A sealing technique that condenses an unprotected mind into a solid whole to prevent any harm. What? Do you have an issue with the name?"

“No, no…”

Haruno Sakura quickly waved her hands in denial. She had a deep understanding of this young master's greatest weakness - his poor naming skills. In the ninja world, apart from some basic ninjutsu names that were relatively simple and straightforward, which ninjutsu with a little bit of uniqueness wasn't named as loudly as possible?

I won't mention the Chidori and Raikiri of Kakashi Hatake, or the Lotus and Peacock of Might Guy. Even Sasuke Uchiha's mid-air spinning kick is shamelessly called the Lion's Chain. In comparison, Mizuki is really too lazy to name it.

"That's good."

Mizuki asked Sakura to open the scroll and then continued.

"See the magic circle in the center? When you practice using shadow clones, stand on it and input chakra, and a mental barrier will be formed to protect you and smooth out violent mental fluctuations. When you are able to learn this technique and imprint it on yourself to control it, you won't need this scroll. This is something I used before, but I don't need it now, so I'm giving it to you."

"Thank you, Master." Sakura happily put it away, "Can't I learn now?"

"You think the study load is not heavy enough?" Shuimu reminded, "I was originally going to teach you when you have made further progress in the Sealing Technique. Now I am giving you a ready-made one to use, just to ease your study pressure. And there is a limit. If you have more than 20 Shadow Clones, you must be especially careful and don't put too much pressure on yourself."

"knew."

Haruno Sakura replied happily.

Sakura would not believe everything Mizuki said. Mizuki would analyze some of the problems she often encountered, and then take out a scroll from his magic ninja tool bag and tell her what to do, and the problem would be solved.

In Sakura's heart, this master may not be invincible, but there are not many things that can stump him. Maybe if she begs a little more, there might be something better, but this is enough for now.

"I have never seen Master use the Chakra Shield Fusion Nature Transformation before. How come you know so much about the development of this technique?"

"What's so strange about this? I've thought about doing what you're doing now before, but I just didn't succeed."

Although the chakra shield is very primitive in its form change and cannot be compared with the top-level techniques such as Rasengan, the difficulty of integrating the chakra property change is much easier. However, Hatake Kakashi could not integrate the lightning attribute chakra property change into the Rasengan, and then successfully created Chidori. Mizuki also had no way to deal with the Rasengan, and tried to use the chakra shield, but failed again.

It's not that it was a complete failure, it was just a useless result, it was really useless, not as good as a high-level fire escape. Shuimu was not interested in "playing with fire and getting burned", so he had to give up the idea of ​​a fire attribute chakra shield and started to develop a second attribute. With the fire attribute, Shuimu was not very eager for the wind and lightning attributes that also belonged to the attack type. In the choice between earth and water, earth escape was given priority because it could make up for the weakness of physical skills.

However, before Mizuki could complete the cultivation of the second attribute, the cultivation of the Sage Mode was successful, so Mizuki no longer had to rush to make an earth attribute chakra shield. In front of the more useful sage techniques, ordinary ninjutsu really had no advantage. In layman's terms, if you can drive a Gundam, what else do you need a bicycle for?

"Failed? Oh! It seems that Master doesn't have the earth attribute, so he doesn't use it?"

After saying that, Sakura nodded, thinking she had guessed it right.

Shui Mu had no intention of correcting him, and said to the disciple who had too many ideas: "Since you don't want to give up, and I have given you a chance, I will not let you be perfunctory in your studies. If you fail the test, you will be tempered by the devil's training!"

…

Mizuki and two Mist Ninjas were traveling through the dense jungle of the Land of Fire. Since time was not urgent, the three of them did not move very fast.

"Luckily, I'm working with Mr. Mizuki this time. If it was someone I'm not familiar with, I don't know if I could get along well with him!"

Shy Chojuro said to Mizuki.

"Am I easy to talk to?" It seems that in the Water Country, although I don't have a strong presence, I am still easier to negotiate with in the eyes of others.

"Mr. Mizuki is joking. I'll trouble you to capture the Yanliu Jonin."

"Hmm? Arrest?" Mizuki turned around and said to Chojuro who was grinning, "Did you make a mistake? The mission I received was to stop the assassination. Of course, if my allies ask me to do so, I will try my best!"

"But……"

"Stop talking, Chojuro!"

The experienced Chunin Kanryu stopped Chojuro from speaking in time.

"I'm sorry to trouble Mizuki-sensei. The troubles of the Hidden Mist Village will naturally be solved by the Mist Ninjas. But before the reinforcements arrive, Mizuki-sensei will need to take more care of it."

Allies are just allies after all. Konoha and the Mist Ninja each have their own tasks. They can cooperate, but they still have to be cautious about stealing the limelight from each other.
