From the night of genocide, marching towards the strongest.

At that moment, Sasuke twirled the short sword in his hand, performing a sword flourish. The short sword, which was originally wrapped in lightning bolts, suddenly turned crimson and emitted wisps of white steam.

Fire Release: Carving Technique!

Sasuke's Fire Release chakra input was just right. Too much chakra would burn the stone black and cause it to crack, while too little chakra would result in insufficient power to carve out the details and textures of the stone.

It was just right!

What's worth mentioning is Sasuke's current gaze. Although on the surface his gaze is completely focused on the stone sculpture and he doesn't move, if you look closely at his eyes, you'll find that his pupils have no focus at all, they are just scattered.

This kind of gaze is often only found in blind people.

Five Senses Sealed - Sight!

Not far from Sasuke was Yakumo Kurama, who was also holding an easel and intently sketching.

Sasuke's eye transformation was naturally due to Yakumo Kurama's request, as he would inevitably one day transplant and fuse the Mangekyou Sharingan. According to the original work, it took Sasuke at least a month to go from transplantation to complete advancement to the Eternal Mangekyou Sharingan.

Sasuke is a very cautious person. The thought of being blind for more than a month in the future fills him with a sense of crisis.

Even if there is someone he trusts who protects him at that time, he will not lack this sense of crisis in the slightest.

Therefore, he must prepare for that day in the future, even if he loses his sight, he must have the ability to protect himself!

Moreover, after six months of sculpting with a closed vision, Sasuke felt that he gained even more improvement after each sculpting session.

Although Sasuke cannot see the appearance of the stone sculpture in front of him, he uses his hearing to listen to the sound and marks of each cut on the stone, in order to judge the approximate appearance of the sculpture.

He had previously used his hearing, honed over six months of training, to detect Sakura's abnormal heartbeat.

A gentle, warm breeze caressed Sasuke's face, and he felt completely immersed in nature.

With his hands and heart completely focused on the stone carving, he had been carving for nearly two hours. The meticulous control of his chakra had already left him somewhat exhausted.

But this inexplicable sense of closeness and harmony with nature actually revitalized Sasuke's spiritual power.

Chapter 35 The Monster Inside Sasuke's Heart?

At this moment, the features of the sculpture in front of Sasuke became more prominent and clearer, with only the eyes missing.

As the saying goes, "the finishing touch is the finishing touch when painting a dragon," the dragon's body is its form, and its eyes are its spirit.

Only after the eyes are finished can they be considered to have been imbued with spirit.

This also applies to sculpture.

Sasuke simply raised his short sword in front of the stone sculpture, then stopped and remained silent for a long time.

Suddenly, he sheathed the short knife in his hand, a flash of crimson light passed through his eyes, and his vision returned to light.

Kurama Yakumo has a strong talent and also possesses a bloodline limit that closes off the five senses.

When she uses it, it is much stronger than that of other members of the Kurama clan who have awakened bloodlines that have closed off their five senses. The difference between the two is equivalent to the difference between a regular Sharingan and a Mangekyou Sharingan.

However, Yakumo Kurama has not yet fully matured; he can only be considered to possess kaleidoscope-level talent, and has not yet fully awakened.

Sasuke's own spiritual energy was by no means weak; Kurama Yakumo's ability to seal his five senses in his normal state could not prevent him from doing so.

However, as soon as Sasuke activates his Sharingan, his vast and pure Yin Release power can instantly break the seal that Yakumo Kurama placed on him.

"call!"

Sasuke exhaled and tossed away the stone fragments, revealing the entire stone sculpture. Sasuke had sculpted an ordinary-looking, unremarkable young man. Every detail and every line on his face was sculpted perfectly, except for the eyes, which made the sculpture lack spirit and soul.

"Sasuke-kun, aren't you going to finish this piece?" Yakumo Kurama, who had already finished his sketch, walked over and asked in confusion.

Sasuke shook his head and said, "Forget it, I'm not confident enough to capture the essence of this work yet."

Kurama Yakumo carefully observed the stone sculpture for a while, then asked softly, "Is this man someone important to Sasuke?"

Upon hearing this, Sasuke smiled smugly: "I guess so, or rather, a special existence."

Is he Sasuke's Uchiha clan member?

Kurama Yakumo nodded as if she understood, but of course she couldn't possibly guess that Sasuke's sculpture wasn't of the Uchiha clan, or even anyone from this world.

It was his past self!

Sasuke stared at the stone sculpture for a while, then looked at Kurama Yakumo beside him and smiled, "Yakumo, your body and spirit are getting better and better. It seems that yoga is really suitable for you."

Yoga is a very gentle form of exercise. It does not involve any strenuous movements. Instead, it focuses on physical postures, breathing exercises, and meditation to improve flexibility, coordination, and endurance. By enhancing people's physical, psychological, emotional, and spiritual abilities, it aims to achieve harmony between body, mind, and spirit.

This sport is very suitable for Yakumo Kurama, who is in poor physical condition.

Kurama Yakumo smiled slightly and said softly, "I have to thank Sasuke for teaching me this precious training technique."

Yoga is indeed very suitable for Yakumo Kurama. She has been practicing for more than two years and can clearly feel that her body is getting better and better.

She even became increasingly adept at manipulating illusions, which delighted her and her parents.

If Sasuke hadn't told her that yoga is a long-term practice, her health, though improved, wouldn't have undergone any significant changes.

Therefore, it is suggested that she wait until she enters puberty and her body begins to develop before becoming a ninja. Right now, she can't wait to become a ninja.

Although he was anxious, Yakumo Kurama had already endured so many years, so a few more years wouldn't hurt.

Sasuke didn't tell her where the technique of yoga came from, and Yakumo Kurama never asked. She just felt that the technique was very similar to the way monks practiced.

She guessed that Sasuke had been obtained from the Uchiha clan, since the Uchiha were one of the oldest and most prestigious clans in the ninja world, possessing countless ancient texts.

"You're too kind. You've helped me a lot these past two years."

In addition to using his bloodline limit to seal Sasuke's vision and help him simulate the feeling of blindness during training, Yakumo Kurama also used his genjutsu labyrinth ability to assist Sasuke's genjutsu training.

Although they were friends, Sasuke valued reciprocity and always returned the favor. In addition to yoga, Sasuke also taught Yakumo some ninja training knowledge and Uchiha genjutsu experience.

He treated Naruto the same way, not only to give himself another punching bag and opponent, but also as an investment.

Judging from the information Naruto told him last night, this investment seems to be paying off soon.

"Let's skip the formalities and get started, Yakumo."

Upon hearing this, Yakumo Kurama hesitated for a moment, then asked, "Do we really have to do this, Sasuke-kun?"

Sasuke nodded and said calmly, "I'm counting on you!"

His tone was extremely calm, yet it carried a sense of decisiveness.

Seeing that Sasuke was determined, Yakumo Kurama sighed inwardly and had no choice but to agree, "Alright then."

As soon as he finished speaking, Yakumo Kurama formed a hand seal and softly shouted, "Illusion Technique—Inner Illusion!"

............

"Is this... Sasuke's inner world?"

This is a desolate wilderness in the dark of night, surrounded by ravaged wildflowers and rows of rotten, ashen trees, as if some monster has completely plundered the vitality of this land.

High in the sky, a huge, blood-red full moon hung high, its crimson light illuminating the earth.

Yakumo Kurama was no stranger to the Blood Moon, which he described in books as a natural wonder.

But the blood moon before him truly startled Yakumo Kurama, and an ominous feeling emanated from it.

The shadow cast by the blood moon's light on the parched earth twisted and struggled, seemingly forming a blurry monster with ten tails.

The moment Kurama Yakumo vaguely saw the monster, he felt waves of negative thoughts, filled with twisted, ferocious, insane, destructive, and plundering thoughts, crashing into his brain like a raging storm.

"What kind of monster is this!?"

Kurama Yakumo's eyes widened in shock, and he asked loudly with a look of terror on his face.

"Don't be nervous." Just as Kurama Yakumo was filled with fear, Sasuke appeared beside her at some point and comforted her.

"Huff, huff, huff," Yakumo Kurama gasped for breath, then asked incredulously, "Sasuke-kun, is this the world inside your heart?"

"This is terrifying..."

Before he could finish speaking, Yakumo Kurama swallowed the rest of his words and sighed inwardly.

As expected, Sasuke wasn't as calm as he appeared. How could a normal person remain calm after encountering something like that?

Sasuke must have encountered such extreme pain and immense pressure that caused this incredibly terrifying monster to grow within him.

"It's not really my inner world, it's more like a fragment deep within my genes," Sasuke shook his head and said calmly.

“However…” Sasuke changed the subject and continued, “However, its birth was indeed related to my deliberate efforts to promote it.”

"Yakumo!" Sasuke looked at Kurama Yakumo, who had an incredulous and even somewhat frightened expression, and said seriously, "I need you to use your unique bloodline limit to make it real!"

"What!?"

Chapter 36: The Dark Ido Belonging to Sasuke.

What Yakumo Kurama saw was not the real Ten-Tails, nor even a projection.

It was merely a product created by Sasuke in order to awaken the Mangekyou Sharingan by imitating the grudge demon "Ido" of Yakumo Kurama from the original timeline.

This was created by Sasuke based on the id theory of his past life's psychology master Freud, combined with psychology books from this world and Uchiha genjutsu hypnosis.

The id is the earliest and most primitive part of the personality, located in the biological genes. It is a reservoir of biological impulses and desires, unrestricted by morality or right and wrong, and pursues the greatest possible satisfaction of the self.

It is all the psychological accumulations that are fixed in the body at birth, and it is the irrational and unconscious life force, drive, instinct, impulse, desire and other psychological abilities of a person that have been suppressed and excluded for a time.

In the West, the id is called original sin or the devil in one's heart, while in Eastern cultures it is referred to as inner demons or inherent evil.

Sasuke's yoga meditation emphasizes clearing away distracting thoughts, achieving a state of clarity and stillness, and immersing himself in his own ethereal and tranquil world.

In order to cultivate his inner demons, Sasuke would do the opposite after completing his daily yoga meditation practice, infinitely amplifying the distracting thoughts, desires, and instincts in his mind. To achieve even better results, Sasuke even resorted to self-hypnosis.

Then, using the Sharingan's genjutsu, he collected and sealed away the negative emotions he had accumulated, a process that took over a year.

A few days ago, Sasuke's primal biological impulses and desires finally manifested in his heart as a monster resembling the shadow of the Ten-Tails!

A monster born from the deep genetic lineage of the Uchiha clan!

"Sasuke, do you know that if you do this, the negative emotions in your inner world will no longer be just simple negative emotions, but will completely transform into a second personality of yours, a personality with dark desires, and it might even turn against you and take over your body!"

Kurama Yakumo anxiously advised, she really didn't want this boy's personality to change drastically and turn him into a monster full of resentment, revenge, and desire.

Besides sealing the five senses and the realm of illusion, Yakumo Kurama's bloodline limit also has the ability to transform between reality and illusion, turning the fake into the real. In the original timeline, she once drew a lightning bolt on the Hokage Building in the picture frame, and as a result, the Hokage Building in reality was also struck by lightning.

The negative emotions in her heart had no effect whatsoever on Kurenai Yuhi's seal, and the resentment and darkness continued to grow, becoming the dark personality within her—Ido.

Even at the very end, Ido, this illusory being composed of negative emotions, separated from Yakumo Kurama's body and became a real monster capable of descending into reality.
