Interrogation
Surrounded and blocked by the mud controlled by Yichen, and also due to the Jonin, he slowly retreated back the way he came.
But just as the Jonin to the spot where he had been knocked down into the mud, Yichen activated his attack.
The mud, which had been brought under control, suddenly flew up from the ground and enveloped the Jonin.
This Jonin had excellent sensory abilities; he sensed something was wrong the moment he stepped into the mud. He immediately tried to dodge.
But Yichen was more decisive than him. He didn't wait for the other party to fully enter the ambush area, but instead attacked as soon as he saw that the other party might discover a flaw.
Although Yichen didn't Jonin trap the Jonin immediately, he quickly cornered him by taking the initiative.
Then, they successfully wrapped the person up before they committed suicide.
However, this time it was different from when he killed the two Chunin; he simply turned the mud into rocks and crushed them to death.
This time, Yichen controlled the mud to perform Chakra Seal technique, sealing the Chakra of this Jonin.
Then Yichen created a Mud Clone to guard it. This Mud Clone was only recently created because only the Mud Clone could control the mud formed by Yichen's Kekkei Genkai.
After dealing with the Jonin, Yichen followed the direction in which the Chunin had left.
The opponent didn't run far. Yichen had the Light-Weight Rock Technique to catch up quickly, and he also had Sensory Ninjutsu to search for him. So, this Chunin eventually became Yichen's prisoner.
Although the process was somewhat bumpy, Yichen was very satisfied with the result. He captured two ninjas who knew Lightning Release, one of whom was Jonin.
Instead of returning to the camp, Yichen found a relatively secluded spot nearby and Interrogation the two men.
Interrogation of ninjas is difficult. Yichen had not studied any specialized interrogation techniques, nor had he learned this in the Ninja Academy's library. Furthermore, ninjas are often people of strong will, with ideals and beliefs, and are not so easily subdued.
However, the Interrogation by ninjas was relatively simple, because ninjas themselves possessed all sorts of strange and unusual abilities. Yichen happened to know one of them: Genjutsu.
Yichen 'Yichen Genjutsu technique was not high-level, but his mental strength was exceptionally strong.
The C-rank Genjutsu — Interrogation —was used by Yi Chen. Under Yichen's powerful mental strength, the Chunin didn't last long before revealing the information Yichen wanted.
Unfortunately, although this person is Lightning Release ninja, he has not learned the Lightning Release Stimulation Method. His understanding of the Lightning Release Stimulation Method is not Yichen, a fan of the original work.
After all, although Iwagakure does not have a complete Lightning Release Stimulation Method that can be directly trained, it does have a lot of experimental data based on the speculations of its predecessors.
Before deciding to learn the Lightning Release Stimulation Method, Yichen had obtained all of this information from the village and had carefully analyzed it.
However, it wasn't entirely without gain. This Chunin, after all, lived in Kumogakure and had more knowledge of Lightning Release than Yichen. Although he hadn't learned the Lightning Release Stimulation Method, he had heard about it from others. This information was still somewhat helpful to Yichen.
After Interrogation the Chunin, Yichen decisively finished him off.
Then came the Jonin, but this time things didn't go so smoothly. This Jonin had a very strong will; Yichen estimated that his willpower was quite good among Jonin. He was probably the kind of genius who had the potential to become Elite Jonin.
Therefore, although Yichen's Genjutsu was successfully cast, Genjutsu effect on the opponent was not very profound.
It's necessary to explain the C-rank Genjutsu, Interrogation, here.
This Genjutsu is easy to learn. If the target is an ordinary person, even a Genin who learns this ninjutsu can easily obtain the information they want.
However, this Genjutsu has a major flaw.
Unlike normal combat-type Genjutsu, combat-type Genjutsu focus on control. As long as the opponent doesn't break free from the Genjutsu, their life or death is in my hands. Even if the opponent knows they're under Genjutsu, it's all for naught if they can't break free.
For example, with Tsukuyomi, Kakashi knew immediately that he had fallen into its trap, but he just couldn't break free.
But the Genjutsu Interrogation is different; it aims to make the victim believe they are not under Genjutsu. The caster must create an environment that the person under the Genjutsu can believe, so that they will reveal the information they want.
However, if the information being asked is extremely important, the other party will be subconsciously very wary, making them reveal it will be extremely difficult. This is because the other party will become alert the moment they are questioned and realize they have been Genjutsu.
Fortunately, when the Genjutsu of Interrogation is cast, it will make the victim feel somewhat confused. While the victim is not fully conscious, an illusion is created to make them feel that saying these words is justified.
The environment that Yichen created was a teaching environment. In the illusion, this Jonin on a disciple, and to increase credibility, Yichen modeled the disciple's appearance after the future Fifth Raikage, Darui — Land of Lightning.
In the illusion, Darui is asking his teacher with anticipation about the training process of the Lightning Release Stimulation Method.
"Darui wants to learn the Lightning Release Stimulation Method? Well, you need to train your Lightning Release to a certain level before you can try. Otherwise, Lightning Release won't help you increase your speed; it will only damage your cells."
"Teacher, teacher, could you please tell me in detail the cultivation steps of this Lightning Release Stimulation Method?" Yichen asked, mimicking the tone of his three disciples when they sought his guidance.
"Haha, alright. The first step in the Lightning Release Stimulation Method is to achieve precise control. You should know that controlling Lightning Release is the most difficult of the five elements. I'll teach you. Find a lake and try to precisely use Lightning Release to attack multiple targets simultaneously. When you can use the Chakra of a C-rank Lightning Release to attack hundreds of targets at the same time, you can move on to the next step."
"So, teacher, what's the next step?"
Upon hearing this question, the Jonin's brows furrowed even more deeply, as if he sensed something and was struggling against some kind of consciousness.
Upon seeing this, Yichen immediately tightened his control and exerted all his strength.
In the illusion, seeing that the teacher remained silent, Darui asked again, "Teacher, teacher, what's the next step? Please tell me!"
"Next step? Next step, you reduce the power of your Lightning Release as much as possible, reduce it to... Ah!"
"Damn Iwa ninja, you actually tried to steal our Kumogakure's ninjutsu!" The Jonin broke free from the Genjutsu.
This is also the characteristic of this Interrogation, because once the victim realizes they are under its Genjutsu, the ninjutsu becomes ineffective. Therefore Genjutsu, when this technique was invented, no effort was put into figuring out how to keep someone who has realized they are under Genjutsu trapped in Genjutsu.
Those who Interrogation this Genjutsu either don't realize they're under Genjutsu and reveal all the information they know, like the Chunin before; or they realize they're under Genjutsu and can easily break Genjutsu, like the Jonin in front of us.
Yichen ignored him and used the Genjutsu Interrogation again, but this time it had no effect. In the Jonin, the Lightning Release Stimulation Method had become a sensitive term, and even anything related to practicing Lightning Release had become very sensitive.
Given Yichen's mastery of Genjutsu magic, it was impossible for him to say anything more.
"What a pity!" Although he didn't know how many prerequisites there were in practicing the Lightning Release Stimulation Method in the Kumogakure, the second step should be missing just a few words.
Having confirmed that no more useful information could be obtained, and to prevent any unforeseen complications, Yichen killed the Cloud ninja Jonin and then destroyed the ruler-body using Fire Release.
Yichen had been fighting this Jonin for quite some time, and he had a lot of information about himself in his head. Yichen didn't want to leak the information, after all, there weren't many ninjas who knew that he had developed Porcelain Release. Most of these people were in the East Front Camp. As long as there were no traitors in the camp, Yichen's secret could be kept for a while.
But Yichen was overthinking it. His intelligence had already been sent out, and through at least two channels.
Neither of these two channels were the most likely sources of espionage that Yichen believed existed, and it was during this First Shinobi War that...
In this First Shinobi War, Yichen left no survivors and cleaned up the battlefield, so theoretically there was no possibility of a leak.
However, Yichen lacked experience. The Chunin Kuromaya who left earlier, although not strong, was experienced. Unsure if he could escape, she left a message during her escape.
To prevent Yichen from finding it, the Chunin left several marks. At least two of these marks were found by the Cloud ninja who came to make contact half a day later and successfully delivered to the Third Raikage's desk.
Even if Yichen found these marks, it would be useless, because the battle between Yichen and the two Cloud ninja was also seen by a pair of eyes in the dark. The owner of these eyes was none other than the White Zetsu clone.
Since the Land of Rain, the White Zetsu clone has not shown itself to Yichen again, not for any other reason than out of caution.
When Yichen was in the Land of Rain, he deliberately went to inform the Akatsuki Organization, during which he killed a White Zetsu clone that was tracking him. He also used his Sensory Ninjutsu to monitor another White Zetsu clone from a distance.
At the time, the White Zetsu clone didn't think there was anything wrong, but later, Yichen appeared and ruined Danzo and Hanzo's plans, which made the White Zetsu clone take notice of Yichen.
Once the intelligence was gathered, it was easy to connect Yichen with the clone who delivered the message, so White Zetsu guessed that the clone might have died at Yichen's hands.
Although Yichen had set a trap to create the illusion that his true form wasn't nearby, White Zetsu naturally cautious, and afterwards, he stopped observing Yichen closely wherever he appeared.
The White Zetsu clone never approached this East Front Camp; it merely observed it discreetly from a great distance.
While Yichen's Sensory Ninjutsu can indeed distinguish subtle differences between trees possessed by White Zetsu clone clones and other trees when used specifically, it is difficult for Yichen to do so without a specific target.
Therefore, the White Zetsu clone witnessed Yichen's entire battle, but Yichen failed to detect the White Zetsu clone even when he used his Sensory Ninjutsu twice.
The White Zetsu clone naturally knew that Kuromaya had also left a message. If Kuromaya's information wasn't passed on this time, the White Zetsu clone would find a way to get the message to the Cloud ninja.
Yichen is so closely associated with the vessel of the Rinnegan, White Zetsu would definitely choose to eliminate him if given the chance.
However, Yichen's carelessness made White Zetsu underestimate him. In White Zetsu's view, how could someone who could ignore such simple information possibly set a trap for him?
