Regarding genjutsu, Ryun had always been very interested.
However, he knew that without the Sharingan, he was destined to not go far on the path of genjutsu.
So what he needed to do was not make himself into a genjutsu expert, but research how not to be controlled by an expert's genjutsu.
Actually, releasing genjutsu is not difficult.
Unless it was an extremely special genjutsu, such as Tsukuyomi or Kotoamatsukami, most genjutsu could be released through two methods.
One, calming the chakra within the body that was disturbed by the genjutsu, which could be done by oneself recovering or with the help of a partner.
Two, relying on strong willpower or pain sensation to force the brain to realize that a genjutsu was appearing before one's eyes.
Unfortunately, what Ryun wanted to do was face genjutsu of Tsukuyomi's level and still not be controlled.
Or, after being controlled, be able to quickly realize he was under control, and then release the genjutsu.
This required Ryun to devise a method that could, when he alone was hit, rely on instinct to detect the presence of the genjutsu and quickly break free from the control.
Obviously this was a very difficult thing. If everyone could do it, then the category of ninjutsu known as genjutsu could directly disappear from the ninja world.
Regarding this, Ryun actually had some ideas. He had two existing examples for reference.
One was that jinchuriki could rely on the tailed beast inside their body to help release genjutsu. Two, Deidara, in order to counter Itachi's genjutsu, came up with a rather clever little trick.
Deidara concentrated chakra in his left eye and covered his left eye with his hair, causing the scenes seen by his left and right eyes to be different. Apart from himself, no one else knew about this.
A genjutsu user unaware of this would normally cast genjutsu, allowing Deidara to see a normal scene, and he would then realize he was under genjutsu.
With these two examples first, Ryun then had his own concept.
First, he could be like Deidara, making himself always see something whose existence others were unaware of, setting this thing as a reference point.
This way, after he was hit by genjutsu, the reference point before his eyes would disappear, and he would immediately realize he was under genjutsu.
And Ryun just happened to have such a reference point he could utilize, which was the system's text display box.
This thing would undoubtedly stay there all the time, and would not disappear under any circumstances.
Furthermore, according to Ryun's simulation experience, even Yamanaka Inoichi did not know of its existence after reading Ryun's mind. From this, it could be inferred that no genjutsu user could possibly simulate it before Ryun.
With this reference point, what Ryun needed to do next was, after the reference point disappeared, to break the genjutsu he was under himself, or, more aggressively, rely on some mechanism to automatically release the genjutsu.
This required Ryun to have something inside his body that could actively help Ryun calm his chakra.
Other ninjas did not possess this condition. Jinchuriki needed to rely on the tailed beast inside them for help, so what could Ryun rely on?
The answer was already inscribed on Ryun's chest, which was the Strength of a Hundred Seal.
Ryun could make fine adjustments to the Strength of a Hundred Seal, adding some curse mark conditions.
For example, if the chakra within Ryun's body underwent a certain special change, the Strength of a Hundred Seal would release chakra to calm the chakra within Ryun's body, achieving the effect of automatically releasing genjutsu.
To accomplish this, Ryun needed to continuously test what effects he would experience when under genjutsu, and how to adjust the Strength of a Hundred Seal so that it could accurately help Ryun automatically release genjutsu.
If a comparison must be made, it was like the process of collecting data for AI simulation.
This was also the main reason Ryun came to Team 8.
Although Yūhi Kurenai's genjutsu collapsed at a touch before the Sharingan, she herself was an absolute genius with a genjutsu attribute as high as 10 points in the eight ninja attributes. It was just a pity she did not have a stronger bloodline to allow herself to advance further.
So what Ryun needed to do next was to have Yūhi Kurenai teach him and use genjutsu on him, so that Ryun could continuously collect data to modify his own Strength of a Hundred Seal.
This was a work measured in years. If he did not become Yūhi Kurenai's subordinate, Ryun could hardly believe Yūhi Kurenai would work hard to help him.
These points had already been written into the simulation by Ryun during his last guidance. Next, it depended on whether Yūhi Kurenai would agree or not.
[Yūhi Kurenai only thought briefly before agreeing to this point, but she demanded that your learning of genjutsu must proceed step by step. You heard the implication, which was that Yūhi Kurenai could not teach you unconditionally.]
Ryun was already prepared for this.
What Yūhi Kurenai relied on was her own skills in genjutsu. The relationship between Ryun and Yūhi Kurenai was only that of jonin and subordinate. There was indeed no reason for her to impart everything unconditionally.
But that was only for now. Ryun believed Yūhi Kurenai would change her view of him in the future.
[Under Yūhi Kurenai's guidance, you began genjutsu training, and recorded the disturbances caused by genjutsu within your body, then started trying to modify the Strength of a Hundred Seal. At the same time, you did not forget to continuously help Hinata strengthen her body, and were responsible for the team's meals.]
[Under your multi tasking, you quickly became close with everyone. Even Kiba and Shino started seeking you out to discuss training experiences, because you were undoubtedly the strongest among the several genin.]
[Confident in your own strength, you also shared some ninjutsu experiences. Soon, in the eyes of Shino and Kiba, you became the real leader among the four.]
[During task leisure time, you did not forget to cultivate feelings with Tenten. Because in this life you became a ninja and had also written several published novels, you had enough time and money to devote yourself wholeheartedly to Tenten. Your feelings warmed up rapidly.]
[In the blink of an eye, the Chunin Exams began. How you should participate in the Chunin Exams became a problem Yūhi Kurenai had to consider. Four people participating in the Chunin Exams did not conform to the rules.]
Seeing this, Ryun was somewhat surprised. He only then reacted that he now also had to participate in the Chunin Exams.
But he should be excluded, right. Just as Ryun was thinking this, Hinata chose self sacrifice.
[Hinata chose to withdraw from the Chunin Exams, leaving the opportunity to you. To your surprise, both the Hyūga Clan and Yūhi Kurenai agreed to this choice. While Hinata breathed a sigh of relief, she also realized she had been completely given up on.]
Ryun scratched his head. realizing he could only be sympathetic but powerless to help regarding this.
This time he was simulating Tenten, not Hinata. Otherwise, he would definitely have tried to change Hinata's personality.
For now, he could only compensate Hinata doubly and try to make Hinata stronger.
Sure enough, his simulated self in the system did just that.
[Because Hinata was completely given up on, she also gained complete freedom, hardly ever restricted from going out, and had more contact time with you. She also put down her burdens, ate her fill every meal, and then eagerly enjoyed your massages.]
[You noticed Hinata's strength had grown significantly, but you were not clear on exactly how much she had grown. Yūhi Kurenai signed you, Kiba, and Shino up for the Chunin Exams, and ninjas from Sunagakure also arrived in Konoha.]
