Konoha: Unable to learn ninjutsu, they had to develop their own.

The next moment, he felt a flow of chakra on the surface of his body.

Then...

The previous scene returned to normal.

"How about it?"

"I've been hit by a spell, but I can feel that I'm under an illusion; there's a noticeable sluggishness."

"That's it."

After a moment of contemplation, Kurenai Yuhi said, "This shows that the protection is effective."

"That's true, but at this level, it can only be considered a warning, far from being a mental defense technique. Moreover, this is only a C-rank Naraku-sight technique."

Chiba was not satisfied with this.

Yuhi Hong nodded.

This is true.

The Naraku-sight technique is only C-rank in difficulty. Although it is practical, its power and effect are not strong. It is mainly used to scare people and provide short-term control.

“Generally, illusions attack the head first. For example, the Naraku Sight Technique attacks through the eyes, and the Dark Walk Technique does the same. I think you can concentrate your mental energy more.”

Kurenai Yuhi offered her own idea.

More concentrated?

Chiba pondered for a few seconds, then quickly adjusted the distribution of his mental energy—

The extra mental energy on the chakra protective barrier was not removed.

But at the same time.

He covered the skin of his head with a protective layer made entirely of spiritual energy.

Two layers of defense!

"try again."

"it is good."

Kurenai Yuhi was very cooperative.

She was also very interested in Chiba's research, even though the development of this technique might restrict genjutsu ninjas like her, not everyone could learn this secret technique.

and.

It is extremely difficult.

Kurenai Yuhi's initial assessment was that even for a ninja like her, who was skilled in illusion techniques and mental powers, the learning difficulty was still at least A-rank.

"This time it's still the Naraku-sensei technique."

"it is good."

Another attempt.

this time……

Chiba could perceive the effects of the illusion more clearly, and he only experienced a momentary daze before recovering without falling into the illusion.

"I was not affected by magic."

"Incredible, but that's because your mental energy is stronger than that of an ordinary person. Even if an ordinary ninja learns this technique, they will at most be the same as you were before."

"You're right."

Chiba nodded, and then he asked Kurenai Yuhi to use a more advanced illusion technique.

Anyway, their class has been doing D-rank missions recently, which don't involve dangerous battles, so even if they expend some chakra, it shouldn't be a problem.

Kurenai Yuhi was very cooperative.

She then used the Tree Binding Kill, the Three Absolute Cherry Blossoms, and the Falling Cherry Blossom Nami Technique.

Chiba easily broke free of the first one.

The second type was not disturbed by the cherry blossoms at all.

The third type...

Chiba was slightly sleepy and somewhat listless, but she did not fall into the "sleep" state that the illusion had anticipated.

"Your technique is effective, but it is very difficult to learn."

"Not enough, hmm, could you demonstrate your illusion a few more times? But this time, I hope you will use it on my shadow clone."

Chiba wanted to use his senses to see the specific effects of each of Kurenai Yuhi's illusion hand seals, a level of perception that only he himself could achieve, and only at very close range.

He walked over to Kurenai.

Hong was a little puzzled, but still helped gently.

She demonstrated her illusions one by one.

Chiba sensed the changes in his mental state brought about by each hand seal.

"I understand!"

"what?"

Kurenai looked at Chiba.

"This seal can help gather spiritual energy, especially if combined with other hand seals..."

As Chiba spoke, he formed a "巳" seal.

Chiba's self-awareness is stronger than his perception of others. He can keenly sense that his own spiritual energy is gathering at an accelerated rate, three to four times faster than before.

Although the increase is not significant, ordinary ninjas do not have such delicate mental control, so hand seals are the best way.

With this seal, the mental defense technique is half complete.

"Please try again."

"it is good."

Yuhi Hong nodded.

It's still a sleep-inducing illusion.

Then, Chiba felt a little sleepy, but it quickly dissipated.

"The effect is stronger."

success!

Chiba released the hand seal, took out a pen and paper and quickly wrote it down. After he finished writing, he recalled it for a moment and wrote down the flaws.

"Although successful, it requires hand seals to achieve maximum effect, and its use in battle is quite demanding, requiring further optimization."

Kurenai Yuhi, who was standing to the side, was immediately speechless.

Is this still in need of optimization?

She felt she was already perfect, but in the other person's eyes, she still had a lot of flaws. It's true what they say, comparisons are the thief of joy!

Kurenai Yuhi was beginning to understand the meaning of Asuma's words of advice—

Don't try to compare yourself to Chiba.

Chapter 153 Delivered to My Doorstep? How Can I Accept This?

"Chiba-kun, I think this is more than enough."

Kurenai couldn't help but say.

"It's enough to deal with genjutsu ninjas who need to use hand seals, but some genjutsu don't require hand seals at all. If we wait until the opponent uses them before we use hand seals to deal with them, it will be too late."

"..."

have been offended.

Kurenai's lips twitched as she secretly sized up Chiba, realizing that the other person wasn't really targeting her.

His expression was so sincere.

"If we use illusion techniques without hand seals, the power and effect will be reduced considerably, right?"

Yuhi Kurenai said.

Later on, apart from the Sharingan, other genjutsu were simply not enough.

Not long after.

Kurenai Yuhi had already realized what was happening.

"Teacher Hong!"

Shino and Hinata spoke in unison.

Intelligence is key.

She thought for a long time and said, "If we don't use hand seals, we need to use some movements to guide and release the illusion."

The other party's achievements have already proven themselves.

"Isn't the key to illusions to be undetectable? If the other party already knows it's an illusion, what's the point of successfully casting it or how powerful it is?"

"Ninja tools?"

Can light tools also be used as a medium?

“I haven’t tried it, but it should be possible. I’ve read the Second Generation’s notes, and he mentioned a concept of illusion sword technique that uses sword movements to release illusions.”

This is under the condition that the strengths are evenly matched.

Kurenai Yuhi pondered for a few seconds.

This is also the significance of research institutes.

"Chiba-kun, thank you."
