If Sakura wants to further explore her potential in this area, it's not impossible, but if she does that, she'll have too much to learn. The sealing technique that's already on the right track, plus the medical ninjutsu that she's fairly diligent in, both require a lot of time to learn and accumulate before she can make any achievements. Illusion is also a powerful weapon for her to exert her strength.

If you add this original ninjutsu that takes a long time to practice, I wonder if Sakura can allocate enough time to take care of so many things. As a registered official ninja in the village, you also need to do some low-level tasks from time to time. The difficulty is not very high, but it is a waste of time, and it is also an indispensable part of a ninja's career to increase his experience and experience.

Mizuki didn't give a clear answer at the moment, so Sakura misunderstood what Mizuki meant. She thought that the result of such random thoughts and efforts was not promising, so she asked anxiously:

"You also think there is no future? As expected, the things I came up with on a whim are still not good enough..."

"On a whim?"

Shui Mu shook his head and replied: "It's understandable that you want to develop in this direction. As long as you can do it without delaying other studies, I have no objection!"

"Do you think this technique will be very powerful in the future?"

"Awesome? I have to correct your concept. Ninjutsu is powerful because the ninja who uses it is powerful. Even if it is a really powerful ninjutsu, only powerful ninjas can learn it. Ninjutsu and ninjas complement each other."

As he spoke, Shuimu stood up and pointed to a row of giant trees not far from the training ground.

"Regarding this unfinished technique, I can demonstrate it to you. Of course, I don't know how to change the properties of earth attributes, so naturally, the powerful physical attack is not the point I want to talk about."

The chakra in front of Mizuki quickly gathered and formed a light blue shield. Then, the color of the chakra shield gradually turned into a bright crimson. Waves of heat spread in all directions, forcing Haruno Sakura, who was closest to her, to take a few steps back.

"The combination of chakra form change and property change is the first choice for most people who want to create a ninjutsu that suits them. However, everyone's understanding is different, and the results are also very different. For example, I formed a chakra shield by dense form change, and the nature change of fire attribute chakra is understood as high temperature, so this ninjutsu with basically no practical value was formed. You can see that if it weren't for my excellent control, I might not hurt the enemy, but I would be scorched first."

Then, the flame shield in front of Shuimu quickly changed its shape and turned into several fireballs, and then under Shuimu's control, they flew towards the giant trees not far away. With the sound of violent flame explosions, a row of giant trees were swallowed by the fireballs and then quickly burned to ashes.

"What a powerful fire escape!"

Haruno Sakura said enviously.

"Amazing?" Shuimu said with a smile, "Actually, this is a failed product that has been abandoned a long time ago. It has no value!"

"A failure? No way? It's obviously so powerful!"

"How big can it be? You've seen the fire escape I used on the sea in the Land of Water, right? How does it compare to this?"

Mizuki's words immediately left Haruno Sakura speechless.

Without waiting for Sakura to answer, Mizuki continued, "It's a small matter that it's troublesome to use, but when you spend a lot of time and effort to find that there are ready-made fire-style ninjutsu that can replace it, or even stronger, just to satisfy the desire to create a new ninjutsu, it's just a waste of time."

Mizuki looked at Haruno Sakura who seemed to be thinking about something and then said, "Your idea is good, but I'm not sure if it will work. I just hope you won't be too obsessed with it, because the unpredictable future may cause you to suffer great losses. If you don't want to give up, you'd better think of a way and don't fall behind in other aspects of your studies."

Mizuki's advice made Haruno Sakura hesitate for a while, but in the end she was reluctant to stop this fighting method that she liked so much.

"I still want to try."

Haruno Sakura said with a stubborn look on her face.

"So what are you going to do? This is not something you can do just by talking about it."

"I plan to use the shadow clone to help me practice. Didn't Master say that the shadow clone is a powerful tool for practice?"

"Then you should also know that I have also said that this is a double-edged sword. If used improperly, it can cause great damage to the spirit."

When Sakura was practicing the transformation of earth attribute chakra, she experienced the cheating function of shadow clone training under Mizuki's reminder, but it was not a trivial matter to use more shadow clones to speed up the practice. Admittedly, with the help of Professor Mizuki's breath-retaining technique, although Haruno Sakura, who had improved her chakra volume, could not compare with Uzumaki Naruto, as long as there were not too many shadow clones, she could still afford it.

This would put more mental pressure on the Shadow Clone when it was released. It was three years later that Naruto used the Shadow Clone to practice the Rasenshuriken under the guidance of Hatake Kakashi. It was too early for Haruno Sakura to do this at this time.

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

"What's this?"

"A part of a large sealing formation. After streamlining its main functions, it has a certain mental defense effect."

Mizuki explained.

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

"Is there such a good thing?"

Haruno Sakura said in surprise.

"As your strength continues to improve, you will naturally have more choices on the road of being a ninja. It's too early for you to come into contact with the prototype of this technique, but even if only a little bit of its function remains, it is still a good little trick."

Mizuki himself had also encountered difficulties with the troubles after the shadow clones were released. It was not like Uzumaki Naruto, who was mentally exhausted by the simultaneous release of a large number of shadow clones in a short period of time, but the huge impact caused by individual shadow clones.

Ordinary shadow clones have a characteristic that once they are attacked with a certain intensity, they will collapse into chakra and disappear. In addition to the time limit, this may be the biggest disadvantage in the eyes of ordinary people.

However, Shuimu didn't see it that way. As an extension of the original body's will, the shadow clone would inevitably pass on all the clone's memories and feelings to the original body after disappearing. Disappearing immediately after being attacked could also prevent further mental damage. Whether this was a coincidence or intentional, it could not erase the huge benefits of this function.
