Itachi sensed the immense power contained within his Sharingan.
Without any hesitation, Itachi used the Dōjutsu within his eyes.
"Amaterasu!"
A burst of black flames appeared directly on Ren's body.
This scene greatly surprised Ren, since the Sharingan is said to be the eye that reflects the soul.
Why is Itachi's Dōjutsu still Amaterasu?
According to Ren's estimation, Itachi's awakened Dōjutsu at this time must at least be a time-related Dōjutsu, or at the very least, a resurrection-type Dōjutsu.
But it was Amaterasu that Amaterasu, and she seemed to have lost her mind and only wanted to kill me? Or is there a limit to the Sharingan? Or is there something wrong with the Sharingan?
Ren, who has no particular talent, can only conduct these simple and crude experiments. He has no psychological burden whatsoever when it comes to experimenting on Ren.
Since Itachi's Dōjutsu didn't meet Ren's expectations, there's no need to worry too much; let him play around on his own.
Ren calmly sensed the Amaterasu flames, the Dōjutsu known as the strongest attack.
First, I tried controlling it using the Fire Man template.
It's very strenuous, and I don't have much control over it.
Next up is the Human Torch template.
It can absorb the heat from Amaterasu's flames, but Amaterasu's flames have the characteristic of never going out.
Even after Ren absorbed all the heat, the fire did not go out and quickly returned to its initial temperature.
This looks like a pretty good power bank!
Ren suddenly thought Amaterasu was pretty good, so he decided to accept it without hesitation.
Ren then activated his Mangekyō Sharingan as well, using Kagutsuchi to control Amaterasu on his body, forming a bead which he held in his hand.
At the same time, the template continuously absorbs the heat from the Amaterasu flames.
Just as Ren was feeling smug, he inadvertently glanced at Itachi opposite him. At this moment, Itachi's right eye was bleeding continuously, and Ren sensed that Itachi's eye power was constantly being depleted.
Ren, as if struck by a thought, controlled the rate at which the template absorbed heat.
Along with this change, the rate at which Itachi's right Mangekyo Sharingan power was being depleted was also changing.
The faster Ren absorbs the energy, the faster Itachi's eye power is depleted; the slower Yuuki absorbs the energy, the slower Itachi's eye power is depleted.
Ren turned his gaze back to the black bead in his hand, speechless.
So what I initially thought was a bug turned out to be just my overthinking.
Before Ren could even think about relying on Itachi's eye power to enhance his template, he immediately used Kagutsuchi to extinguish Amaterasu.
At this moment, Itachi's right eye was faintly white, which Ren noticed with his Mangekyō Sharingan. Although it was not obvious, it was definitely different from before.
Seeing that his Amaterasu was ineffective, Itachi did not hesitate and immediately activated the Dōjutsu of his left eye, known as the strongest Genjutsu.
This information was all included when the Mangekyo Sharingan awakened. Due to the lackluster performance of its strongest Amaterasu, Amaterasu, Itachi didn't have high expectations for its left Dōjutsu, which was touted as the strongest Genjutsu.
To Itachi's surprise, Tsukuyomi succeeded.
When Itachi used Tsukuyomi on Ren felt a surge of ocular power seeping into his mind.
This power of sight seemed somewhat weak to Ren, but it was quite peculiar.
Ren immediately used his own eye power to envelop the foreign eye power and began to use his own eye power to penetrate it in reverse.
Unlike Ren's own simple and crude eye power, this eye power has a very delicate feel to it, like a high-end product.
In Ren's mind, by relying on sheer force and making up for it with quantity when quality was lacking, Ren successfully replaced most of this eye power with his own eye power.
Only the core remains, Ren has no way to remove it. If the core is erased, the Dōjutsu will completely dissipate.
If we compare Dōjutsu to a factory, Ren used his eye power to replace all the workers in the factory with his own.
As for the factory itself, Ren had no way to deal with it.
Either destroy the factory directly.
Either keep it and use it for now.
In the Tsukuyomi World.
Itachi was shocked; this was not what he had expected.
When Itachi activates Tsukuyomi, he can control everything in the Tsukuyomi World: matter, weight, space, and even the most mysterious and unpredictable time.
It was clearly set in an environment resembling an execution ground, a world as clear as a photographic negative.
But what is this in front of me?
It turned out to be the mountaintop where Ren and Itachi were.
Looking down the mountain, you can even see the Ninja Academy's training ground.
And the sun in the sky was radiating dazzling light!
"Itachi, I have to go now. You should go home and rest for a few days; consider it a vacation!"
After speaking, Ren, who was standing not far in front of Itachi, flew away before Itachi could react.
Itachi was left alone on the mountaintop, bewildered.
Itachi was trying to turn Tsukuyomi back to the way he imagined her to be, but as soon as the thought crossed his mind, he felt like he was going to die.
It's not that it can't return to its original form, but the energy expenditure is something Itachi simply cannot withstand.
Itachi tried to make some small changes, such as suddenly producing a long sword in his hand or conjuring up a rabbit.
They accomplished all of this with ease. These items, consistent with Itachi's frugal nature, all resembled black and white photographs, with the Sharingan's dark red base color.
They don't fit in with this world.
Itachi tried to end Tsukuyomi, but the feedback he received was still that his eye power was too much for him to bear.
