It is difficult for everyone to avoid the jealousy of others because everyone is good at similar things and it is difficult to hide one's secrets in front of people with the same expertise.

So far, Mizuki has not encountered many masters who are good at illusion, and the only one who made Mizuki fall into his trap was Uchiha Itachi.

But it was only Tsukuyomi that hit her once, and it was not the real body that was hit, but the physical clone - Hope.

Kurenai Yuhi was able to be promoted to jonin with her expertise in illusion, and it was not a false reputation. In the original work, she was defeated by the stronger Uchiha Itachi because her Mangekyō Sharingan was really unreasonable, not because Kurenai Yuhi's illusion was not strong enough.

If we only talk about traditional illusions and theories, Mizuki is far inferior to Yuhi Kurenai. However, in terms of the breadth and creativity of thinking, Mizuki directly crushes this inexperienced female ninja.

The gorgeous female jonin, Yuhi Kurenai, has the temperament of a heroic woman, but in fact she is a bar girl. She shares the same interests with Mitarashi Anko and in addition to liking street food, she often goes there for a drink.

But now, I have been pregnant for several months and I should not do such things again. At least I should restrain myself for now.

Mizuki and Yuhikuren found a seat facing the street in the teahouse and sat down. After exchanging a few pleasantries, Yuhikuren went straight to the point.

"I wonder if Mizuki Jonin still remembers the illusion he taught Sakura three years ago. I remember it was called Sleeping Scenery, right?"

It was indeed this incident. Mizuki suddenly had a headache. It had been nearly three years, but he didn't expect that Yuhi Kurenai had not forgotten this incident. The persistence and meticulousness of the female ninja should not be underestimated.

"I wonder what you want to know?"

Mizuki answered calmly.

Although this technique has been taught, no one except Shuimu himself knows its true purpose.

But the functions that have been revealed now are already extremely frightening.

Perhaps to outsiders, it is just a powerful and strange illusion, but in front of Yuhi Kurenai, who is well versed in illusion theory, it is only a matter of time before some problems are discovered.

As if she noticed Mizuki's cold attitude, Kurenai Yuhi didn't care. Exploring the secrets of other people's ninjutsu and coming to ask about it were not friendly actions in themselves, so it was normal for Mizuki to be a little dissatisfied.

"I have some guesses that I would like to verify with Mizuki Jonin. The danger of this technique is really worrying. Moreover, when you taught this technique to Sakura, you did not explain to her some of the characteristics and taboos of this technique."

Yuhi Kurenai replied.

"If you don't understand the possible consequences of this technique and abuse it, you may end up making mistakes that are difficult to remedy."

"mistake?"

Mizuki asked back.

"I don't know which ones you mean?"

"Which ones?"

Xi Rihong's face darkened.

"Permanently changing a person's will, this kind of illusion that plays with people's minds is only one step away from being a forbidden technique... No, this is a completely forbidden technique!"

This is actually true. Although there is no such thing as humanitarianism in this world, there are still established rules.

Just like a range ninjutsu that causes indiscriminate casualties on a large scale, it should generally be used with caution because it is likely to damage the foundation of the ninja world.

If a large number of civilians were killed, the ninja group would not be able to continue to exist.

In addition, there are dangerous ninjutsu that will cause irreparable damage to oneself when used, such as the Multiple Shadow Clone Technique. Except for a physical monster like Uzumaki Naruto, anyone else who dared to use this would have been exhausted to death long ago.

The sealing technique of exchanging life for life also belongs to this category.

The other type is the ninjutsu that plays with the dead, which will make everyone feel uncomfortable, such as Impure World Reincarnation.

There are also ninjutsu that completely distorts other people's wills and manipulates other people's bodies. Unlike ordinary illusions, which will not cause much irreparable damage once they are lifted, techniques that change a person's fundamental cognition at the soul and mental level are absolutely forbidden techniques.

Mizuki's illusion, Sleeping Town, is exactly of this kind.

During the Chunin Exam three years ago, Sakura did not cause any harm to Rock Lee due to her lack of strength. However, manipulating mental power and directly harming the soul is definitely a forbidden technique that people fear.

"It seems you know a lot!"

Faced with this expert who is proficient in illusion, Shuimu no longer lied with his eyes open.

After nearly three years of research, an excellent colleague has discovered almost everything that can be discovered. As for some deeper secrets, Shuimu believes that as long as he doesn't tell anyone, no one will know the details.

"So what do you want me to do?"

"Tell Sakura not to use it again. Next time, you might not be as lucky as Rock Lee."

"If this is your request, I refuse!"

Mizuki shook his head.

"It seems that you know something, but you don't know it completely!"

"You use the Sealing Technique to perform an illusion like this. This has definitely transcended the scope of ordinary illusions. The legendary Yin Dun Secret Technique is no more than this..."

Shuimu shook his head:

"Just listen to me first."

The female ninja with a strong sense of justice is a bit stubborn when she gets serious, but Kurenai Yuhi seems to have misunderstood the essence of the matter.

"Whether it's ninjutsu, taijutsu or genjutsu, they all use chakra to hurt people. As for the Sleeping Town, it doesn't matter whether you regard it as a genjutsu or a sealing technique. The effect is no different from other ninjutsu. This technique has many uses, and it's not just a simple attack. Don't use it because ninjutsu is dangerous? This is too superficial. Even a simple fire escape, Great Fireball Technique, is a ninjutsu that can hurt others and yourself. The definition of forbidden techniques is not that simple."

"If that were all, it would be fine, but you didn't warn her to use it with caution."

"Every ninjutsu must be used with caution. As long as it is the power of attack, it should never be used on yourself or your companions!"

"But, you left a method for using this technique on yourself at the beginning, right?"

Mizuki sighed, he was indeed a senior ninja who was proficient in illusion techniques.

Three years ago, Hatake Kakashi guessed that the Genjutsu: Sleeping Beauty could be used on himself because of the activation mechanism of the ninjutsu, and Kurenai Yuhi also realized this fact.

"Every illusion that can be used on oneself is a forbidden technique that must never be passed on to others, such as the Uchiha family's Sharingan secret technique - Izanami!"

"You know all this?"

"I accidentally came across some fragments of words in an ancient book!"

Indeed, the original intention of developing this technique was to counter Shimura Danzo's illusion, Kotoamatsukami, and as a safety measure against the erosion of natural energy. With the research, it gradually began to become what it is today.
