Each visualization of life and death felt real, stabbing into every cell of his brain, instilling a deep pain.
Suddenly, El felt an excruciating pain in his head. Like millions of needles piercing his head, at least that was an accurate description of his condition.
"Argh!" El began to scream in pain while holding her head that was about to burst. All the visualizations of life and death had entered his mind with unstoppable force.
The physical, emotional and empathetic pain within him seemed to be blown away by the endless darkness.
In this state of agony, El struggled to understand what had just happened and how to get out of the endless situation.
El felt as if his mind was being torn apart by the uncontrollable cycle of visualizations that became more intense by the second.
In this despair, El closed his eyes, curled up, trying to shield himself from the burden too heavy to bear in the hope that it would end soon.
"So, you've arrived?" Suddenly, in the endless cycle of suffering, El seemed to hear the voice of a man who spoke in a tone of voice as cold as the ice that froze the world.
"Who... Who's there?" El hissed in a trembling voice. An endless cycle of pain and suffering surrounded his, making her unable to think clearly.
The owner of the voice that sounded like it froze the world responded to El's question. "I am known to you as Uchiha Sasuke." said the owner of the voice in an indifferent tone.
At this shock, El tried very hard to look at the figure. Suddenly, the headache that had been tormenting him began to slowly disappear.
El got up from the sea of blood and repositioned himself. Even after curling up on the surface of the sea of blood, El's clothes were not dirty in the slightest.
"Sasuke?" Upon seeing the man's appearance, El's eyes widened in disbelief.
Uchiha Sasuke looked exactly like in the anime. However, there is a slight difference between them because Sasuke does not have Six Tomoe Rinnegan in one of his two eyeballs.
Both of Sasuke's irises are fiery red in the dark with unique patterns decorating them. El recognized it, the eyeball was the Eternal Mangekyou Sharingan.
In addition, Sasuke has moderately long black hair with pointed ends and his facial appearance is mixed by Indra Outsuki's face.
Sasuke wore a long-sleeved black shirt and gray trousers with a long tattered gray robe, covering his body. Sasuke's suit of clothes reminded El of the anime series Naruto The Movie: The Last.
Dark purple energy surrounded Sasuke's body as Sasuke's basic Susano'o stage was in an active state surrounding him.
That stage is a skeletal structure, such as ribs for basic defense and arms to grasp the body of an unconscious young girl.
But, that was not what El cared about. For now, El felt very confused and curious, why was Sasuke in his subconscious?
"How can you be in my subconscious?" El said in a weak voice, but demanded certainty.
"It's because of the Reincarnation Room." Sasuke was silent for a while and then said. "My soul was forcibly grafted with yours."
Like being slapped by a newly acquired enlightenment. Finally, El understood the two reasons for his confusion.
The first reason, why his nature seems to be very unstable is the result of Sasuke's soul grafting.
The second reason, why his ordinary human self deserves such God-level skills.
"So that's it, now I understand." El said, nodding his head slowly.
Suddenly, El realized that something was wrong and said. "But, if your soul was forcibly transplanted, why did we meet?"
Sasuke paused and turned around, looking at the vast sea of blood. "Every transplant needs time to adapt."
"Oh, is it maybe because my soul is an ordinary human, so it takes a long time to adapt to your soul transplant, which is the reincarnation of Indra Outsuki?"
El walked to Sasuke's side. After arriving beside Sasuke, El followed the direction of Sasuke's eyes looking at the sea of blood.
With a voice full of doubt, El asked. "Sasuke, how long do you think it will take for my soul transplant to adapt?"
Without turning his head and just looking at the endless sea of blood, Sasuke answered El's question with a cold and emphasized tone of voice. "It should be now."
"What!" El was so very surprised and immediately looked at Sasuke.
Sasuke snorted and smiled bitterly, making El feel confused when he saw Sasuke's bitter smile. Curiosity filled El's mind and wanted to ask another question.
However, before asking another question, both of El's eyeballs dripped blood. In the process, the headache that had disappeared entered him again.
"Argh, damn what the hell is going on?" In confusion, El fell to his knees on the surface of the sea of blood and curled up while clutching his eye area.
'It hurts so bad! What the hell is happening to me? My eyes feel like they're being burned by molten lava!' he said through the horrible pain.
El's eyes felt like they were on fire, and both eye sockets were filled with hot lava. His blood flowed more and more from the corners of his eyes and dripped into the sea of blood.
A round purple light that was the size of a pearl with 6 small black balls surrounding it, like small planets orbiting around a sun as the center, like a solar system and entering its body.
Until suddenly, both of El's eyeballs slowly transformed into Six Tomoe Rinnegan. hear
Sasuke saw El agonizing in pain and said in a cold tone of voice. "Your Six Tomoe Rinnegan Ability has mutated and connected with the afterlife probably because of the Reincarnation Room."
"This world is the proof, your soul is starting to build the afterlife realm. Believe me, this realm is not perfect and is only a small part of the afterlife." Sasuke said giving a stern warning.
In the next second, the sea of blood under his feet overflowed and drowned him very quickly.
Frantically, El tried to escape. However, the suction power of the sea of blood was far greater than his strength. This made El could only surrender himself.
Moving the skeleton of Susano'o's arm. Without hesitation, Sasuke threw the unconscious young girl down with El.
With a voice just like the night wind whispering, Sasuke advised. "Remember, there are consequences to Rinnegan's great power. Maybe your true nature will return to the way it was before. But, from now on, you will lose your sense of empathy if you use the Rinnegan Ability too often."
(N/A: From what I researched, Six tomoe Rinnegan and Rinnegan are the same. Only their appearance and abilities are different)
"However, strong emotions can replenish the void in your soul and heart. Remember my warning, don't you dare forget it." Sasuke said in a tone full of pressure.
Until finally, El's whole body had sunk, leaving only the head. With a panicked expression, full of misery for the pain in the head, El tried very hard to embed Sasuke's warning.
In the Naruto anime, Sasuke is a person who once held the power of Rinnegan. Thus, Sasuke better understands the impact of the consequences of Rinnegan owners and holders.
Rinnegan users are often faced with situations where they have the ability to control or manipulate others.
This immense power can change the way they see the world, clouding their sense of empathy and emotional connection with others. For example, the use of this power can make the user more focused on their goals and less attentive to the feelings or needs of others.
Since Rinnegan is an external source of power, it can make the user rely too much on that ability to overcome all problems.
This leads to weakness in other aspects, such as ordinary fighting skills or strategy, as the user may no longer feel the need to develop other, simpler skills.
One of the consequences of Rinnegan is that the user may lose some of their human vulnerability. This immense power can make the user feel invincible or superior, which can reduce the ability to relate to others as fellow humans with weaknesses.
Even worse, Rinnegan can make a person lose control and eventually get swept away in power.
As seen with Madara and Kaguya, excessive use of Rinnegan's power can lead to a loss of control and drift into a quest for power or a desire to change the world according to their vision.
This power can tempt the user to become authoritarian and even lose their sense of empathy.
