From the night of genocide, marching towards the strongest.

"Let's seal him away. Didn't you ask me to do that before?"

Sasuke had asked her to seal away the darkness within her heart.

Yakumo Kurama hesitated on this point. In her view, everyone has their own hidden dark side, and suppressing and eliminating it would only backfire.

Moreover, a person who has no dark side is no longer a complete person.

Kurama Yakumo only agreed after Sasuke insisted, but he never expected that Sasuke's dark side was so terrifying, and he never expected that Sasuke wanted to make his dark side real and release it.

"He does need to be sealed away, but not now."

Sasuke shook his head and calmly replied, "I already know your concerns. Believe me, I will not be devoured by him. On the contrary, his power will be used for my own purposes."

Although Yakumo Kurama possesses the ability to transform illusions, it is certainly impossible for him to transform the Ten-Tails' shadow in his inner world into a real Ten-Tails simply by using a small fragment deep within his body's genes. Not even a hundred or a thousand Yakumo Kuramas could do that.

All Sasuke had to do was transform the Ten-Tails' shadow into his own dark personality. The negative emotions in his heart were ultimately just illusions, the result of his training and hypnosis.

Like a mirage or the moon's reflection in water, it shatters with a single touch. Only Yakumo Kurama can transform it from illusion into reality, turning it into the true dark side of his heart, his second personality.

To become the dark Ido within Sasuke's heart!

"But......"

"Trust me, Yakumo." Sasuke's expression was much more serious this time.

"I still bear the blood feud of the Uchiha clan, and I also bear the mission of reviving the Uchiha clan. Before I achieve this goal, I will never allow myself to die, nor will I allow myself to be consumed by my own darkness!"

To demonstrate his determination, Sasuke brought up the Uchiha clan in his words.

Upon hearing this, Yakumo Kurama remained silent for a long time. He glanced at the vaguely visible monster, then at Sasuke with a resolute expression, and sighed inwardly.

"Ok."

"Sasuke-kun, I'm going to begin now."

"Yes, thank you, Yakumo."

Kurama Yakumo looked at the twisted, crazed monster's shadow, a look of worry flashing in his eyes, and quickly formed several hand seals.

"Illusion is real!"

As Yakumo Kurama unleashed his technique, Sasuke's entire inner world surged with a turbulent current of energy that spread endlessly. Then, in no time, as if the sky had collapsed and the earth had split open, the blood moon dissipated and the earth crumbled.

The Ten-Tails Shadow continuously absorbed a large amount of negative emotions from its biological genes and inner world, including twisted madness, bloodthirstiness, violence, ruthlessness, impulsiveness, and desires.

The shadow of the ten-tailed creature continued to roar with resentment, gradually coalescing into a clearly visible, enormous, and overwhelmingly powerful ten-tailed entity.

very scary!

The moment Kurama Yakumo saw the materialized monster, she felt a surge of emotions—pain, distortion, desire, fear, resentment—rushing into her brain like a tidal wave, turning her face pale and leaving her mind a chaotic buzzing mess.

What terrified her even more was that the most intense and overwhelming emotion emanating from this monster was—devouring and plundering!

It's as if this monster was born to devour and plunder!

Even the Yin Release chakra that Yakumo Kurama used on the monster was largely devoured and absorbed.

Sasuke stood calmly in front of Yakumo Kurama, blocking the power and pressure emanating from the Ten-Tails within him, allowing Yakumo to breathe a sigh of relief.

Once the Ten-Tails took shape, it opened a scarlet, ferocious Sharingan and stared at Sasuke.

Sasuke met its gaze calmly, neither flinching nor backing away, and the two silently stared at each other.

Suddenly, the ten-tailed monster's body trembled violently and began to collapse. Pieces resembling flesh and wood crumbled away, and its once mountain-sized body shrank smaller and smaller as it disintegrated.

It is unknown how much time passed before the ten-tailed monster's body completely disintegrated, revealing what was inside its body.

Chapter 37: Preparations for Awakening the Kaleidoscope.

A figure stepped out from the dust and debris. It was no longer the Ten-Tails, but another Sasuke. However, in appearance, expression, and temperament, it was no different from Sasuke himself, and was just as calm and composed.

The only difference is that Sasuke's eyes are black now, while this Sasuke's eyes are scarlet.

Its eyes were filled with a predatory, fierce, and hungry look that sent chills down your spine at first glance!

"You've separated me from your family; don't regret it later."

Contrary to expectations of a tense standoff, Ido Sasuke stepped forward, glanced at Sasuke calmly, and said indifferently.

"My mind is made up, so why should I regret it?"

Sasuke replied calmly, his tone as if chatting with an old friend.

"I just hope that what I do will be fruitful and achieve what I desire. As for the rest, I don't care."

"Hmph! That's good." Ido Sasuke snorted coldly. The two were originally one, and their thoughts were the same. However, Ido Sasuke's thoughts were too extreme. He acted as he pleased, disregarding morality, ethics, and worldly constraints.

"Yakumo, I'll trouble you to seal him from now on," Sasuke said softly to Kurama Yakumo, who was trembling slightly behind him.

"I will assist you from the side."

"Huh?...Okay, Sasuke-kun..." Kurama Yakumo was taken aback, and stepped forward tremblingly, not daring to look at Ido Sasuke's fierce and hungry eyes.

"What kind of seal should be used?"

“Seal your five senses!” Sasuke replied, looking at the negative Sasuke and saying indifferently, “It must be hard on you.”

"Heh... I'm still worried about you." Sasuke Ido chuckled, his tone sinister and mocking. "Anyway, this emotion will eventually come back to you. I hope you don't break down then and get replaced by me."

"Okay, I understand." Sasuke nodded, responding casually.

"Let's begin, Yakumo!"

To Kurama Yakumo's surprise, the sealing went very smoothly. Ido Sasuke did not resist at all, and even seemed to cooperate.

This relieved Yakumo Kurama, and an idea popped into her mind.

It seems that Sasuke's dark personality isn't that scary?

He seems quite intelligent and rational.

It's just that his eyes are a little scary.

"Thank you for your hard work this time, Yakumo." Sasuke glanced at Ido Sasuke, who was now motionless and seemed to have no sense of anything, and then turned back to thank Kurama Yakumo.

"You're too kind, Sasuke-kun," Yakumo Kurama replied softly, then hesitated before adding, "But Sasuke-kun, is this really the right thing to do? Even though he's been sealed away, he might break free one day, or even..."

Kurama Yakumo still can't understand why Sasuke wanted her to materialize the negative personality in her heart and then seal it away, such a redundant action.

"It'll be alright, Yakumo," Sasuke said softly, looking at Kurama Yakumo, whose face was pale from the exhaustion caused by using genjutsu multiple times.

"Go and rest for a while, leave the rest to me."

Kurama Yakumo remained silent for a moment, then nodded.

"Ah."

As soon as he finished speaking, Yakumo Kurama's figure gradually faded away and disappeared into Sasuke's inner world.

"I hope what I'm doing will awaken my Mangekyou Sharingan."

After Kurama Yakumo left, Sasuke looked at the figure in front of him with his eyes closed and motionless and said softly.

After realizing that it was virtually impossible to awaken the Mangekyou Sharingan through the condition of "gaining love and losing love," Sasuke made two preparations for awakening the Mangekyou Sharingan.

The first, naturally, is to increase one's own mental energy.

The second one is the dark personality in front of us, which is a combination of the primal desires and instincts from the Ten-Tails deep within the Uchiha clan's bloodline genes and the negative emotions of Sasuke's inner turmoil.

Ideally, Sasuke would awaken the Mangekyou Sharingan within a set timeframe by increasing his spiritual energy.

Then Sasuke will eliminate his dark personality just like Yakumo Kurama killed Ido in the original timeline, so that it won't affect him in the slightest.

If Sasuke shows no signs of awakening the Mangekyou Sharingan within the allotted time, then he will choose to release his dark personality and merge with it.

He used his immense negative emotions and spiritual energy to attack the Mangekyou Sharingan.

What will it look like after the fusion?

A drastic change in personality?

Falling into darkness?

Could they even be turned on and have their bodies taken over?

Transform into a beast driven by desire and instinct?

Sasuke doesn't know, he doesn't even know if this method can awaken the Mangekyou Sharingan.

in particular......

"Human emotions and memories become blurred within fifteen days, half are forgotten within three months, and ninety-five percent are forgotten within ten years. After losing all five senses, one falls into absolute silence. All will, emotions, and memories are worn away over a long period of time by the pain of being unable to move or perceive, and by boundless fear and loneliness. In this situation, the human spirit often collapses in a very short time, turning into a completely unresponsive vegetable. This is far more painful than being locked in a dark room or confined. Ha..."

"Dark room" is a psychological term referring to a completely enclosed space where there is no sound or light. In such a situation, even the toughest man with an iron will would quickly suffer a mental breakdown.

Sasuke's dark personality suffers even more than the dark room, as it completely cuts off his physical senses of sight, hearing, and smell. Because he is just a personification of negative emotions, he even lacks the sense of touch.

Logically speaking, even the most negative personality would collapse in a short time after completely losing consciousness, but because Sasuke keeps providing negative emotions to stimulate him, his dark personality does not collapse.

In other words, when Sasuke chooses to merge with this dark personality in the future, he will not only have to merge with the desires and instincts in his bloodline and the negative emotions in his heart, but also instantly endure the boundless loneliness and fear that he has accumulated for more than two years in absolute silence, unable to perceive anything!

If he can't bear the long loneliness and fear of being completely cut off from his five senses at that time, not only will his personality change drastically and be taken over by the negative personality, but he may even become a vegetable without any mental response.

This was a very risky and dangerous thing for Sasuke.

His personality dictates that he doesn't like taking risks, but sometimes there are risks that he has to take. He has never lacked crazy ideas, but he just rarely acts on them.

"Will I overcome all of this with my own will two years from now? Or will I be devoured by you, turning into a beast of desire and instinct? Or will I become a completely unresponsive vegetable?"

"If I can't even take this step, then it proves that my magnanimity is nothing more than this."

Sasuke muttered to himself, the corners of his mouth curving wider and wider, his eyes involuntarily turning into scarlet, ferocious Sharingan, flashing with madness and hysteria.

"Let's wait and see, and see just how magnanimous I really am, hehehehe..."

Hahahahahahahahahahahaha!!!

Sasuke's laughter grew louder and more maniacal, sounding extremely eccentric and insane in the vast emptiness of his inner world, and was terrifying!

Seemingly sensing the change in Sasuke's emotions, Ido, whose five senses were sealed and who was in absolute silence, also curled up a cruel and eerie smile.
