Konoha, reported by the Fourth Hokage at the start.

Chapter 15 Illusions also have no effect.

"Yes, Lord Hokage."

The third generation stepped aside, and Yamanaka Kou stepped forward, coming to Li Yao again, and formed hand seals to cast an illusion.

"Illusion - Hypnosis"

In the Naruto world, interrogation is never conducted through harsh methods such as electric shocks or scraping, which cause unbearable pain and lead to interrogation.

Few ninjas would believe the information revealed by an enemy after torturing them.

They are ninjas, and they only believe in their own ninjutsu.

Therefore, interrogation in the Naruto world is simple and brutal.

Capture the enemy, just like Li Yao did tonight.

The first step after capturing them is to forcibly search their memories using memory-exploration ninjutsu.

If this type of ninjutsu is not effective, the memory cannot be retrieved.

Then use illusion magic to trick the enemy into revealing the information they know.

The third step will only be taken when searching memories and using illusions fail to yield the desired information.

This step is not torture, but dissection to extract the final information from the corpse's flesh.

The principle is actually the same as the first step.

Even after a person dies, as long as their brain is intact, the remaining memories in the brain can still be accessed through ninjutsu.

Only when the enemy cannot die will they resort to torture to extract information.

Thanks to the mutation of his consciousness after transmigrating, Li Yao's memories could not be explored. If the first step was not feasible, then the second step would be taken.

He is currently being invaded by illusion chakra.

The essence of illusion is actually the infiltration and invasion of chakra.

Genjutsu chakra is a special and very illusory type of chakra.

This kind of chakra can silently infiltrate into the chakra of others, and then, when it flows to the brain through the chakra of others, it affects the brain and thus affects the perception of others, forming illusions.

Therefore, breaking the illusion is also very simple.

The core idea is to disrupt one's own chakra.

Genjutsu chakra is a very illusory type of chakra, more like the moon reflected in water. When the water is still, it is impossible to distinguish between the moon in the sky and the moon reflected in the water.

But once the calm water surface shows even the slightest ripple, it becomes easy to distinguish which is the moon reflected in the water and which is the real moon.

Therefore, as long as you can disrupt the flow of your own chakra, just like disturbing the calm surface of water and causing ripples, then the genjutsu will be easily broken.

However, disrupting one's own chakra is not easy.

Especially when under the influence of genjutsu, your senses are overridden. You might think you've mobilized chakra to disrupt it, but in reality, nothing is happening.

Only ninjas who have intensively practiced and mastered genjutsu can develop a kind of instinctive self-protective reaction through regular practice, bypassing the effects of genjutsu and disrupting their own chakra.

Even so, it cannot withstand sophisticated illusions.

At this point, it is usually necessary to have a companion help by using chakra to disrupt one's own chakra in order to break free from the genjutsu.

Or perhaps there's a tailed beast within you that's willing to disrupt your chakra.

Li Yao had no one to help him disrupt his own chakra, no tailed beasts within him, and his chakra was sealed and fixed, so he couldn't disrupt it on his own.

He should have been unable to resist the illusion.

However, once his consciousness and chakra became one, he could still clearly perceive even illusory genjutsu chakra.

At this moment, Yamanaka Kou's genjutsu chakra felt like an invisible stick in his dream, stabbing into his stomach, trying to penetrate deeper.

Li Yao sensed it very clearly.

Just like in a dream, he threw away the genjutsu chakra that Yamanaka Kou was trying to invade.

In short, it is impossible to successfully invade his chakra.

"As expected, even illusions don't work!"

Looking at the motionless Li Yao, Yamanaka Kou reluctantly released his grip, but his face did not show much surprise.

When the technique of disrupting the mind and body proved ineffective, he had already anticipated that illusions would most likely have no effect on the target as well.

After all, the principle of illusion is similar to his Mind Confusion Technique; both require penetrating the target's chakra.

"Lord Hokage." Yamanaka Kou turned around to face the Third Hokage and apologized, "I'm sorry, genjutsu is also ineffective against the target."

"I understand." The Third Hokage stood with his hands behind his back, his expression unreadable, and said calmly, "You can go out now."

Yamanaka Kayu bid farewell and left. When he arrived at the door of the secret room, he glanced back at Li Yao. His intuition told him that this child had a big secret, and a very big one at that.

Unfortunately, his mental manipulation technique had no effect.

It's clear that the Third Generation doesn't intend to tell him this big secret.

He didn't dare ask any more questions, maintaining the wisdom expected of someone in a subordinate position.

After Yamanaka Kaku left, only the Third Generation and Li Yao remained in the quiet, candlelit chamber.

Neither of them spoke; the only sound was the drumming of Li Yao's heartbeat.

Clearly, Li Yao was terrified at this moment, not knowing what the Third Generation intended to do.

The third generation didn't intend to do anything, at least not to kill Li Yao right now.

He approached Li Yao again, formed hand seals, and cast a second-generation illusion technique.

"Darkness Travel Technique"

The Third Generation did not fully trust Yamanaka Kaiu, or rather, he felt that his illusions were more powerful than Yamanaka Kaiu's.

They believed that Li Yao could not withstand the infiltration of his illusion technique, Dark Travel Technique, and chakra.

After all, the Dark Travel Technique was a genjutsu created by the Second Hokage specifically to counter the Sharingan of the Uchiha clan.

It's important to know that the Sharingan is the nemesis of genjutsu; it can directly reflect ordinary genjutsu back at the opponent.

More powerful genjutsu can also be detected by the Sharingan's powerful perception of genjutsu chakra, allowing for proactive countermeasures.

Among Uchiha ninjas who possess the Sharingan, especially the three-tomoe Sharingan, there are very few genjutsu techniques that can be effective against them in the ninja world.

However, even the Dark Travel Technique couldn't break through the three-tomoe Sharingan.

This demonstrates the power of the Dark Illusion Technique, truly deserving of its reputation as an genjutsu developed specifically for the Sharingan of the Uchiha clan.

The Third Generation did not believe that Li Yao could withstand the powerful illusion technique, Dark Travel.

However, the reality is that Li Yao once again blocked the infiltration of the genjutsu chakra.

Moreover, it was very easy, no more difficult than blocking Yamanaka Kaiu's genjutsu chakra.

The third generation remained silent, staring at Li Yao for a long while before suddenly smiling with a slight upturn of his lips.

"If it can be immune to Dark Arts, then can it also be immune to Sharingan genjutsu?"

Li Yao's importance in the hearts of the three generations increased even further.

The Uchiha clan was a major thorn in the side of the Third Hokage, and their greatest strength lay in their mastery of Sharingan genjutsu.

There is a saying that circulates in the ninja world.

"When fighting against Uchiha clan ninjas, never confront the Sharingan."

Just a fleeting moment of contact will plunge you into the genjutsu cast by the Sharingan.

Therefore, they faced off against Sharingan ninjas from the Uchiha clan on the battlefield.

In a one-on-one situation, escape.

If you don't escape and fall into the illusion, you will surely die.

Only in a two-on-one situation, where one person is under the influence of a genjutsu and the other can help disrupt the chakra to break the genjutsu, is it possible to defeat a Sharingan ninja from the Uchiha clan.

This demonstrates the power of the Sharingan's genjutsu within the Uchiha clan.

The reason why the Uchiha clan was able to maintain a love-hate relationship with the Senju clan for many years during the Warring States period and become one of the two strongest clans in the ninja world during that time was due to the powerful genjutsu granted by the Sharingan.

Even without the Mangekyou Sharingan.

Even many Jonin-level powerhouses cannot withstand the genjutsu cast by a typical three-tomoe Sharingan.

But now, the Third Hokage sees a person whose chakra is sealed and imprisoned withstand a genjutsu that even the three-tomoe Sharingan cannot withstand.

So... is it possible that he is immune to kaleidoscope-level illusions?

The third generation looked at Li Yao with an increasingly bright gaze.

If we could be immune... hehe!

The third generation smiled, turned and left.
