If Sakura wants to dig deeper into the potential in this area, it's not impossible, but in this case, there are too many things to learn. It takes a lot of time to learn and accumulate to make achievements, and illusion is also a powerful weapon to exert its strength.

If you add this original ninjutsu that takes a long time to practice, I don't know if Sakura can allocate enough time to juggle so many things. As an official ninja registered in the village, you also need to do some low-level tasks from time to time. It's not very difficult, but there's nothing vague about a waste of time, and it's an essential part of your ninja career to increase your experience and experience.

Mizuki didn't have a clear affirmation for a while, which made Xiao Ying misunderstand Mizuki's meaning, thinking that the results of this kind of random thinking were not optimistic, and could not help but ask:

"Do you also think that there is no future? Sure enough, what you come up with on a whim is still not good..."

"On a whim?"

Shuimu shook his head and replied, "It's okay if you want to develop in this area. As long as you don't delay other homework, I have no problem!"

"Do you think the future of this technique will be great?"

"Powerful? I have to correct your concept. Ninjutsu is powerful, and the ninja who use ninjutsu are powerful. Even if it is really powerful ninjutsu, only powerful ninjas can learn it. Ninjutsu and ninja are mutual. relationship of achievement.”

With that said, Mizuki stood up and pointed to a row of giant trees not far from the training ground.

"I can show you the unfinished art in this idea. Of course, I will not change the nature of the earth attribute. Naturally powerful physical attacks are not the point of what I want to say."

Chakra quickly gathered in front of Shuimu, and then a layer of light blue shield was formed. Then, the color of the chakra shield gradually turned into a bright crimson, and the waves of heat dispersed in all directions, forcing the nearest Haruno Sakura. Don't take a few steps back.

"The combination of chakra's morphological changes and nature changes is the first choice for most people who want to create their own ninjutsu. However, everyone's understanding is different, and the results are also very different. For example, I am formed by dense morphological changes. With the chakra shield, the understanding of the change in the nature of fire attribute chakra is high temperature, so this kind of ninjutsu has basically no practical value. You can also see that if it wasn't for my excellent control, I might not have hurt the enemy. It's going to be burnt first."

Then, the flame shield in front of Shuimu quickly changed shape and turned into several flame balls. Then, under the control of Shuimu, it flew to the giant tree not far away. The tree was swallowed by the flame ball, and then quickly burned to ashes.

"What a powerful fire escape!"

Haruno Sakura said enviously.

"Amazing?" Shui Mu said with a smile, "Actually, this is a failed product that has been abandoned long ago, and it has no value!"

"Failure? No way? It's so powerful!"

"How big can it be? Have you seen the fire escape I used on the waters of the Land of Water? How does it compare to this?"

Mizuki's words made Haruno Sakura speechless.

Without waiting for Sakura to answer, Mizuki continued: "It's a trivial matter to use trouble, but after a lot of hard work, I found that there are ready-made fire escape ninjutsu that can be replaced, or even stronger, just to satisfy the desire to create new ninjutsu, It's just a waste of time."

Mizuki looked at the thoughtful Haruno Sakura and said, "Your idea is very good, but I'm not sure if it will work. I just hope you don't get too addicted, because the unpredictable future may make You've lost a lot. If you don't want to give up, you'd better find a way to not leave other areas of study behind."

Mizuki's advice made Haruno Sakura hesitate for a while, and in the end, she was really reluctant to suspend this kind of fighting method she liked very much.

"I still want to try."

Haruno Sakura said with a stubborn face.

"Then what are you going to do? This is not something that can be done with words."

"I'm going to use the shadow clone to help practice. Didn't the master say that the shadow clone is a tool for practice?"

"Then you should also know. I also said that this is a double-edged sword. If it is not used properly, it will do great damage to the spirit."

When Xiao Sakura practiced the change in the nature of the earth attribute chakra, she was reminded by Mizuki to experience the cheating function of shadow avatar cultivation, but it is not a trivial matter to use more shadow avatars to speed up her practice. It is true that with the help of Professor Mizuki's breath-holding technique, although Haruno Sakura, who has grown in chakra volume, cannot be compared with Naruto Uzumaki, as long as there are not too many shadow clones, he can still afford it.

In this way, the mental pressure when the shadow clone is lifted will be even greater. It was only three years later that Naruto, under the guidance of Hatake Kakashi, used his shadow clone to practice the spiral shuriken. At this time, Haruno Sakura wanted to do this, but it was still too early.

However, it seems that even if Mizuki wants to change Sakura's mind, it is not easy. After hesitating for a while, Mizuki took out a scroll and handed it to Sakura.

"what is this?"

"A part of a large seal formation, after streamlining its main functions, has a certain mental defense effect."

Mizuki explained,

"This has a certain buffering effect on the mental fatigue after the shadow clone is released. If you insist on using the shadow clone, it is best to add this."

"And such a good thing?"

Haruno Sakura said in surprise.

"When your strength continues to improve, you will naturally have more choices on the road of ninjas. You are too early to contact the prototype of this technique, but even if there is only a little function left, it is a good little trick. ."

Mizuki himself has encountered difficulties after the release of shadow clones. It is not the mental exhaustion caused by the simultaneous release of a large number of shadow clones in a short time like Uzumaki Naruto, but the huge impact caused by individual shadow clones.

Ordinary shadow clones have a characteristic, as long as they are attacked with a certain strength, they will turn into chakras and disappear after collapse. Aside from the time limit, this is probably the biggest disadvantage in the eyes of the average person.

However, Mizuki didn't see it that way. As an extension of the will of the body, the shadow clone will inevitably pass all the memories and feelings of the clone to the body after disappearing. It disappears immediately after being attacked, and it can also avoid further damage to the spirit. Whether this is coincidental or intentional, it doesn't take away the enormous benefits of this feature.
