"Genjutsu, simply put, is a technique that interferes with the enemy's five senses using chakra, causing them to fall into illusions."
Yuhi Kurenai's tone was serious as she began her explanation.
The five senses refer to vision, hearing, smell, taste, and touch.
In genjutsu, the focus is often on vision.
The most classic visual genjutsu is the Sharingan.
There is a saying in the ninja world: when fighting a member of the Uchiha clan, never look into their Sharingan.
Because a single glance will cause an explosion... Oh, no, wait, it's an illusion.
"If two genjutsu users are battling, the winner will depend on the power of Yin Release, that is, mental strength."
Yuhi Kurenai looked at Yukawa and said, "Your mental strength is naturally stronger, so you're suited to learn genjutsu."
"What about mine?" Yukawa asked.
Yuhi Kurenai couldn't help but ask.
"Yours is stronger than your peers as well."
Yuhi Kurenai paused for a moment, not saying the rest of the sentence.
If Kurenai's genjutsu talent was 6000, Yukawa's genjutsu talent would be at least 10,000 or higher.
But that doesn't mean her talent wasn't good.
In fact, before meeting Yukawa, Kurenai was the most talented genjutsu user she had ever seen.
Excluding the Uchiha clan.
They don't rely on genjutsu talent; as long as they can activate their Sharingan, they can use genjutsu.
"Alright, enough talk. Let's try it out directly."
Yuhi Kurenai clapped her hands and said, "Let's start with the most basic genjutsu, Kageyose no Jutsu."
Kageyose no Jutsu is a D-rank technique that creates a terrifying black phantom to scare the enemy.
The black phantom moves slowly and is harmless, with the greatest advantage being that it splits when attacked.
It's somewhat like a special version of the Shadow Clone Technique.
"Watch closely and learn well."
Yuhi Kurenai slightly slowed her hand seals.
Soon, a humanoid black shadow emerged from behind the sofa.
It was pitch black, emitting a cold aura.
With Yukawa and Kurenai already prepared, they weren't scared.
This genjutsu was only useful for surprise attacks.
"Your turn."
Yuhi Kurenai released the genjutsu and looked at them expectantly.
It took her a whole day to learn this genjutsu, but Yukawa and Kurenai had better talent, so they might learn it in half the time.
Yuhi Kurenai blinked, then froze.
In front of Yukawa, a humanoid black shadow suddenly appeared.
Yuhi Kurenai instantly felt as if she was under a genjutsu.
The speed was faster than she had expected.
"Damn!"
Kurenai looked at the empty space in front of her, a look of frustration on her face.
Her talent was indeed not as good as Yukawa's.
But she quickly gathered herself, tried several times, and finally successfully cast Kageyose no Jutsu.
The summoned black phantom wasn't humanoid, but rather something like a strange creature.
"Kurenai, your talent really is better than mine," Yuhi Kurenai said with a gratified smile.
But Kurenai didn't feel happy at all.
Comparison is painful. Compared to Yukawa, she still had a bit of distance to cover.
"Uncle Kurenai, can you teach me the second genjutsu?" Yukawa asked, looking at the new entry.
"Although you've learned Kageyose no Jutsu, you're not yet proficient."
Yuhi Kurenai said seriously, "After practicing for two days, I'll teach you a new genjutsu. Remember, don't rush."
"Uncle Kurenai, look."
Yukawa clapped his hands, and a humanoid black shadow appeared instantly.
"How… how is this possible?"
Yuhi Kurenai couldn't help but widen her eyes.
"…"
Kurenai was silent.
Not only did he learn the technique in such a short time, but had he completely mastered it as well?
The proficiency of a technique is determined by how quickly it's cast and how powerful it is.
Yukawa's second cast was much faster than the first, almost reaching the limit speed of Kageyose no Jutsu.
As for the reason, he had some extra help.
[E-rank Technique Entry: Kageyose no Jutsu]
[Trigger Condition: Successfully cast the technique.]
[Effect: The technique automatically reaches proficiency level.]
[Note: It has a synthesis path. Three E-rank genjutsu entries can be synthesized into a D-rank genjutsu entry.]
When the entry was obtained, Yukawa's mind was flooded with experience points, as if he had practiced the technique countless times.
"Your talent is even stronger than I imagined!" Yuhi Kurenai exclaimed, excited.
The ninja world hadn't seen a true genjutsu master in a long time, since all the fame had been taken by the Uchiha clan's Sharingan.
Now, Yukawa gave her hope—perhaps one day, he could achieve that level.
As his mentor, Kurenai's family would be famous, perhaps even becoming the Yuhi clan.
"…"
Yukawa remained silent, looking at her expression.
What should he say? "I'll bring my talent to the Yuhi family?"
"I'll teach you the second genjutsu now."
Yuhi Kurenai took a deep breath and said, "Genjutsu: Naraku no Mi."
Yukawa's eyes lit up.
This genjutsu was well-known in the original series, used by Orochimaru and Kakashi.
Though the difficulty was still D-rank, its power far exceeded that of Kageyose no Jutsu.
It shows the enemy their deepest fears, creating a heart-striking effect.
After Yukawa cast it once, he obtained a new entry.
[E-rank Technique Entry: Genjutsu: Naraku no Mi]
[Trigger Condition: Successfully cast the technique.]
[Effect: The technique automatically reaches proficiency level.]
[Note: It has a synthesis path. Three E-rank genjutsu entries can be synthesized into a D-rank genjutsu entry.]
Yukawa took a deep breath.
With his current chakra, casting three techniques consecutively had already drained most of it.
This was why the ninja academy only teaches the Three-body Technique at the beginning.
But Yukawa didn't stop, continuing to ask Yuhi Kurenai to teach him the third genjutsu.
After all, a new entry was just around the corner.
Stopping halfway through would be like watching an action movie that suddenly pauses—if it breaks now, the impact is lost.
Yuhi Kurenai had already recognized his talent. Seeing that he still had some strength left, she agreed to continue.
[E-rank Technique Entry: Genjutsu: Three Bizarre Sakura]
[Trigger Condition: Successfully cast the technique.]
[Effect: The technique automatically reaches proficiency level.]
[Note: It has a synthesis path. Three E-rank genjutsu entries can be synthesized into a D-rank genjutsu entry.]
Genjutsu: Three Bizarre Sakura creates illusions of floating petals to confuse the enemy's vision.
In terms of effect, it is weaker than Genjutsu: Naraku no Mi, as it's only used to deceive sight.
Yukawa had used up most of his chakra and sat down to rest.
His speed in learning was impressive, and it was partly due to his talent, but also because these three techniques had a low learning difficulty.
Yuhi Kurenai watched the absurd scene just now, and after a moment of silence, she suddenly smiled, realizing the truth.
This was a man among men, a genius among geniuses.
How could she win?
Turns out, she was just an ordinary person.
