In a small grove of Konoha.
"Sasuke, what do you think is the biggest advantage of the Sharingan?"
Uchiha Kei sat leisurely on the ground, a piece of unknown grass root dangling from his mouth.
"The biggest advantage..."
Sasuke frowned and thought for a moment.
"I think it's Genjutsu!"
It's not wrong to say that the Sharingan's Genjutsu is prevalent throughout the entire Shinobi World.
Uchiha Kei nodded first, then shook his head.
"What you said isn't entirely wrong, but I don't think so."
Sasuke was taken aback, his eyes filled with confusion.
My brother said...
Is the Sharingan's greatest advantage Genjutsu)?
"Genjutsu varies from person to person."
Uchiha Kei's eyes had somehow awakened the Three Tomoe.
The Three Tomoe, arranged in an extremely regular pattern, rotated slowly.
What do you think determines the strength of Genjutsu spell?
"Eye power, Chakra!"
Sasuke answered without hesitation.
Uchiha Kei smiled.
"Yes, but you've overlooked one element."
Sasuke looked at him, puzzled.
"Mental power! The invisible and intangible mental power also governs the strength of Genjutsu."
Mental strength?
The confusion in Sasuke's eyes deepened.
This word...
This was the first time he had heard of it.
Uchiha Kei suddenly activated his Genjutsu.
In an instant, Sasuke's eyes went blank.
Within the Genjutsu space, a sea of fire was raging, a black mist shrouded the sky, and piercing roars could be heard from time to time.
Sasuke looked around in fear.
Is this Jing's Genjutsu?
"This is my Genjutsu space. What do you think?"
Uchiha Kei appeared beside him.
"It's terrifying."
Sasuke said with a hint of fear.
This place is a complete apocalyptic scene, making it hard not to feel fear.
What's your impression of this place?
Uchiha Kei then asked.
Sasuke gradually let go of his fear and carefully examined the Genjutsu space.
The raging inferno released its intense heat relentlessly, even distorting the very space around it.
Thick black fog completely obscured the sky, creating a sense of oppression, like dark clouds pressing down from above.
The roars emanating from the thick fog instilled a sense of dread in everyone.
"Reality."
After thinking for a long time, Sasuke uttered two words with difficulty.
Yes.
The only feeling that Uchiha Kei had of the Genjutsu space was that it was real.
If Uchiha Kei hadn't pointed it out, he wouldn't have been able to tell it was Genjutsu at all!
You got it right.
Uchiha Kei smiled with some relief.
As one of the two chosen ones in the Naruto World, Sasuke's talent goes without saying.
Even without the hatred of his clan's extermination, his progress is still clearly visible.
It's about wiping out an entire clan and opening a single Tomoe...
It's been criticized to some extent.
"The realism of Genjutsu affects its strength."
"Imagine if you enter Genjutsu without realizing it, is your life or death still in your own hands?"
Sasuke pondered carefully.
Although this was the first time he had ever heard of this concept, but...
That makes so much sense!
"This is a manifestation of mental strength. The strength of one's mental strength can affect those who are stronger than you but have weaker mental strength."
Uchiha Kei sighed.
Back then, he used Genjutsu to forcibly awaken Itachi's Mangekyo. At first, he thought it was because the Three Tomoe given by the system were stronger.
In three years, although his talent wasn't enough to master Ninjutsu.
However, it was enough for him to use the Sharingan in various ways.
Through repeated attempts, he became aware of the existence of mental energy.
The superposition of his spiritual power from his previous life and the spiritual power in this life makes his spiritual power far surpass that of ordinary people.
Even Itachi, compared to his spirit, is far inferior.
This is also the real reason why he was able to use Genjutsu to force Itachi to awaken the Mangekyo.
"So that's how it is..."
Sasuke murmured to himself.
"Then how should one train their mental strength?"
Uchiha Kei shrugged. "I don't know either."
Sasuke:...
I don't know what you're talking about!
"However... training beyond one's limits should improve mental strength, right?"
Uchiha Kei said uncertainly.
He had speculated about improving his mental strength and had even taken action to do so.
Perhaps it's because his mental strength started at a high level, and he hasn't improved much over time.
Sasuke nodded solemnly.
Pushing beyond limits...
Sasuke's gaze gradually hardened.
He was willing to endure any hardship or fatigue as long as it allowed him to become stronger!
Uchiha Kei waved his hand, and the Genjutsu space instantly vanished.
"Back to the previous question."
Uchiha Kei casually sat down on the ground.
"The Sharingan's greatest advantage is its dynamic vision."
Uchiha Kei flashed and appeared to Sasuke's left.
Sasuke was startled, and before he could react, the figure on his left had already disappeared.
"No matter how fast you go, the Sharingan can see everything clearly."
The voice came from Sasuke's right.
"Dynamic Vision..."
Sasuke was somewhat confused.
Dynamic vision is indeed very powerful in Taijutsu combat.
However, in the case of Ninjutsu, the usefulness of dynamic vision is greatly reduced.
After all...
Ninjutsu has a very wide coverage area, so what good is dynamic vision?
I know what you're thinking.
Seeing his bewildered expression, Uchiha Kei smiled.
"Dynamic vision doesn't seem to be very useful in Ninjutsu, but..."
What if dynamic vision and Ninjutsu were combined?
A ball of deep blue Chakra appeared in his hand.
Lightning Release: Lightning Cutter!
With a low growl, Uchiha Kei's figure appeared like a phantom, leaving several afterimages in his wake, and instantly appeared beside a tree a hundred meters away.
"Sizzle!"
A piercing sound rang out.
Sasuke's mouth was agape.
In his line of sight, Uchiha Kei moved at incredible speed, appearing a hundred meters away in the blink of an eye and piercing straight through the tree.
That speed...
That's terrifying!
Gently withdrawing his hand, Uchiha Kei slowly returned to Sasuke's side.
"Do you understand now?"
Sasuke nodded, thought for a moment, and then shook his head.
He understood the movements, but he didn't understand the properties of Chakra.
"We possess Chakra nature within our bloodline, essentially five types: fire, water, lightning, wind Chakra, and earth."
"This is the nature transformation of us ninjas."
Deep blue Chakra reappeared in Uchiha Kei's hand.
"This is Lightning Release Chakra."
Sasuke a little excited and reached out to touch it.
The moment he touched it, a subtle electric shock traveled through his skin from the deep blue Chakra.
"Most of us in the Uchiha Clan possess fire-type Chakra, but there are exceptions, such as my lightning-type."
Do I also possess the properties of lightning?
Sasuke said excitedly.
Uchiha Kei nodded.
In the anime, Sasuke is an expert in using lightning, and his self-created Lightning Release: Kirin is an S-rank Ninjutsu.
"Lightning Cutter is incredibly fast; without the aid of the Sharingan's dynamic vision, this move is practically suicidal."
Uchiha Kei said calmly.
Sasuke nodded solemnly.
"So..."
Uchiha Kei laughed, a laugh that was innocent and pure.
"Now it's time to begin cultivation."
Seeing Uchiha Kei's smile, Sasuke subconsciously shuddered.
Why do I feel...?
Are you going to get scammed?
