From the night of genocide, marching towards the strongest.

This is a muddy area that has been submerged in water for a long time, with lush aquatic plants and soil consisting of humus and peat bogs.

Outside, an endless green miasma sealed off the area, making it seem as if it would never end.

As soon as Sasuke stepped onto this land, his feet were pulled by the swamp and began to sink. He quickly put chakra into the soles of his feet and stopped sinking.

"Lord Sasuke, you've arrived."

A sound like a thunderclap, like a howling wind, rang out, and a giant lizard as big as a mountain appeared in Sasuke's field of vision. With the slightest movement, it had the feeling of covering the sky and the sun!

"Yes, thank you for your help this time, Shuzaki."

Sasuke nodded slightly and said in a deep voice, "I will be staying here with you for a while, so please take care of me during this time."

The tuatara showed him great respect, perhaps because it had never seen a human since it could remember, and maybe it was lonely.

The giant lizard Shuzaki has great respect and cherishes every generation of contractors, and he is doing the same for Sasuke now.

"Although I'm clumsy, I will protect you, Lord Sasuke!"

It was still a booming sound, carrying a strong sense of honesty and simplicity.

Sasuke smiled slightly; he was still quite at ease with the Shuzaki Giant Lizard.

Not to mention that after signing the blood pact, the summoned beast cannot harm the summoner.

Moreover, the Shuzaki Giant Lizard has been quietly guarding Shuzaki Castle for over fifty years because of a last wish of Shuzaki Gossa.

This is enough to show that the Shuzaki Giant Lizard is an extremely loyal summoning beast!

Sasuke gave a soft "hmm" and then began to busy himself with his own affairs.

He first used ninjutsu to clear a clearing in the swamp, then took out a storage scroll and released a series of items sealed inside, including food and an operating table.

The operating table was surrounded by various nutrient solutions that Sasuke had prepared himself.

Sasuke's medical ninjutsu was learned from Kabuto Yakushi, a guy who only knew a tiny bit of medical ninjutsu.

Naturally, they would also prepare all sorts of medicines and nutrient solutions!

Sasuke wasn't sure how long he would be unconscious, and although he was strong now, he was still just a mortal.

He couldn't do what the Six Paths experts did—stay up all night, eat and drink without rest—so he had to prepare these things.

"Multiple Shadow Clone Techniques!"

After doing all this, Sasuke crossed his arms and released the Multiple Shadow Clone Technique.

Although Sasuke wasn't particularly interested in the Multiple Shadow Clone Technique.

But he still learned this ninjutsu because his next plan required the use of hundreds or even thousands of shadow clones!

Bang bang bang!

After a violent and massive surge of chakra, nearly three hundred shadow clones instantly appeared around Sasuke!

"call....."

Sasuke's face was slightly pale, and he was breathing heavily.

That Naruto guy can unleash a thousand shadow clones at once without even breaking a sweat.

But Sasuke is far from being able to do that yet. Releasing nearly three hundred shadow clones in an instant almost drained two-thirds of his chakra.

However, even so, Sasuke's chakra is still much stronger than his original self in the original timeline. In this respect, even Sasuke three years later might not be able to match him.

After all, Sasuke put in a lot of effort in both mental and physical training, and he even used countless high-end nutritional supplements.

As soon as the three hundred shadow clones appeared, they simultaneously performed several stretching movements and took several slow, deep breaths. Then they sat cross-legged, closed their eyes, focused their minds, and began to regulate their breathing and cultivate their inner energy.

meditation!

Meditation held a pivotal position in various religions and spiritual practices throughout past lives, including Zen meditation, yoga, internal alchemy, and even the art of tea ceremony.

By cultivating oneself around the path of the mind, one can transcend oneself, be freed from afflictions, and regulate one's state of mind.

Even setting aside the mystical aspects of religion, previous scientific research has found that meditation, this ancient method, can indeed relieve fatigue and reduce mental stress.

It can even improve physical condition, helping to lower blood pressure, relieve migraines and chronic pain, and address a range of other negative health issues!

In order to integrate with the dark personality within himself, Sasuke must inevitably endure the pain and boundless fear that the dark personality could not perceive for more than two years.

It also incorporates his own dark, sinister, and brutal negative emotions, as well as the bestiality, killing instinct, and wildness from the Ten-Tails' original bloodline!

To be honest, it was Sasuke's self-proclaimed state of mind from over four years of training, as well as his immense spiritual energy.

There is absolutely no guarantee that merging with this dark personality without making a mistake will go wrong.

If Sasuke were to rashly choose to fuse, nothing unexpected would happen.

They will either become a vegetable or a beast driven by their desires and instincts.

Therefore, Sasuke used the Multiple Shadow Clone Technique, hoping that the mental purification and tranquility generated by the shadow clones during meditation would serve as reinforcements for his fusion with his dark personality.

To ensure that they are not assimilated by the dark personality.

This is Sasuke's purpose in creating shadow clones. After the shadow clones are released, the memories and experiences will return to the original body. Sasuke had also previously discovered that shadow clones used for meditation do not cause much fatigue or memory burden to the body, and are almost negligible.

But these quantities are far from enough!

Sasuke slowly glanced at the shadow clones around him, silently took out a few of his own specially made pills from his pouch, swallowed them, sat cross-legged and meditated for a while, and then created three hundred more shadow clones to meditate.

And so, after spending an entire afternoon, Sasuke finally managed to create 1,200 shadow clones.

"Alright, alright?"

Sasuke could sense that he was nearing his limit, and that forcing himself to continue would only have the opposite effect, so he stopped, took a few tonics, rested for a while, and recovered his strength.

Looking at the operating table in front of him, he remained silent for a while, gritted his teeth, lay down on it, and closed his eyes.

Beside the operating table, two shadow clones were monitoring his every move to prevent any unforeseen events or accidents from happening to him.

.........

Chaos, pitch black, seemingly an endless spiritual world.

A beam of light appeared and then transformed into the likeness of Sasuke.

In front of Sasuke is the dark personality—Ido Sasuke.

At this moment, he was still in a state of absolute silence with his five senses sealed, but unlike two years ago.

At that time, Sasuke Ido was filled with a chilling aura of indulgence, debauchery, and darkness.

At this moment, there was only silence for Sasuke Ido!

Absolute silence!

It was as if Sasuke Ido had already become a vegetable, showing no mental response whatsoever.

Even under such close observation, Sasuke could only barely sense a faint, almost imperceptible, mental fluctuation.

That slight fluctuation of spirit conveyed no fear, no resentment, not even loneliness or confusion!

Only nothingness!

Sasuke sighed, stepped forward, and said softly:

I will bear your pain and carry your loneliness.

After saying that, Sasuke placed his hand on Ido Sasuke's head.

Chapter 89 The Seven Senses of Time, Heaven's Constant Establishment! Devouring Heaven and Earth, High Control of the Nest!

Outside, just as Sasuke lay on the operating table and closed his eyes...

The shadow clones outside also began to get busy.

In an instant, Sasuke's body was covered with all sorts of patches, connected to various instruments of all sizes, such as brain neuron wave detectors, electrocardiogram monitors, blood pressure monitors, bioelectric sensors, and so on.

To check on Sasuke's physical and mental condition at any time.

Some of these items can be bought on the market, while others can only be obtained through Konoha Hospital.

Of course, Sasuke obtained all of these things from Granny Cat.

As for the energy and power required to operate these instruments?

Do not ask!

The answer is chakra!

After completion, two of the shadow clones remained standing closely beside Sasuke, observing him.

The remaining few stood in front of a row of sophisticated testing instruments, looking very focused.

Suddenly, Sasuke's breathing, which had been quiet and steady with his eyes closed, slowed down considerably, though it remained very steady and the change was extremely subtle.

However, he was still noticed by the two shadow clones who had been observing Sasuke.

"The patient's blood pressure is dropping rapidly, quickly approaching the standard value of 90/60 mmHg, and this rate and intensity are gradually increasing..."

"Body temperature, heart rate, metabolism, and other physiological activities are gradually decreasing at a faster rate, indicating that the animal is about to enter a hibernation-like state..."

"The brain's nerves have entered a state of paralysis, there are fluctuations in mental state, and the brain's bioelectricity is gradually disappearing, indicating that it has entered a deeper state of sleep..."

As soon as Sasuke's main body changed, the shadow clones observing from various instruments quickly reported back.

At this moment, Sasuke had entered a state similar to an animal's "hibernation mechanism." In this state, Sasuke's breathing was extremely weak, and his heartbeat was unusually slow.

At this point, stimulating him with pain will only cause his body to tremble slightly, but it will not wake him up.

"The body's brain activity is rapidly disappearing!!!"

"The cell's bioelectric currents are rapidly disappearing!!!"

"Danger!!!"

"Danger!!!"

The shadow clones' expressions changed, and as soon as they finished speaking, dozens of shadow clones in the distance simultaneously dispelled the spell and returned to their original forms.

In an instant, Sasuke's extremely weak brain nerve fluctuations and cellular bioelectric currents recovered slightly, and Sasuke's breathing became visibly faster.
