From the night of genocide to the strongest

With a low, crisp sound, the bone marrow puncture needle drilled a small hole in the bones of Sasuke's waist.

"snort..."

Bone marrow puncture examination usually requires the injection of anesthesia, but in order to be able to clearly sense the changes in the body, Sasuke did not use any anesthesia in this experiment.

Even though he had prepared his mental equipment before, the sharp pain that penetrated his bone marrow still made Sasuke tremble and let out a muffled groan.

The shadow clone in front of the instrument first observed the main body for a while. After seeing that the main body was fine, he said: "The bone puncture is completed. Now we will inject the first-generation cells. Be prepared and stay awake."

Sasuke nodded slightly.

The shadow clone pressed a button, and the puncture needle instantly stopped rotating and started injecting instead. The light green fluorescent first-generation cell liquid was slowly injected into the bone marrow cavity of Sasuke's body through the injection tube.

After the first-generation cells were injected, Sasuke frowned instantly and sweat broke out on his forehead.

"The body's vital signs are disordered, and the heartbeat and blood pressure are abnormal..."

The shadow clone observed the changes on the instrument screen, recorded it in the experimental notes, then walked to the main body and asked in a deep voice:

"What does it feel like?"

The main body is conducting a transplant experiment and has no spare time to record the experimental data, so this issue must be left to him.

"The body seems to be burning. It feels like ants biting the flesh and blood. It hurts and itches, but there is also an inexplicable coolness. No..."

Sasuke carefully sensed the changes in his body. After a moment of silence, he continued: "It should be said that it is refreshing, the kind of refreshing feeling as if you are on the grass and the breeze in the forest is blowing against your face."

"Um!"

The shadow clone nodded, kept writing in his notes based on what the main body said, and continued to ask:

"Have you felt the increase in eye power and strength?"

Sasuke shook his head and said calmly: "Not yet, but I can feel that the cells in my body are intersecting with the first-generation cells, entangled, and fighting. It seems that everyone wants to devour the other."

The vital activity of the first-generation cells is extremely strong and it is highly corrosive. If an average person injects the first-generation cells into the body,

If nothing else, the first-generation cells would immediately eat up his body cells.

But this does not mean that it is a good thing. On the contrary, the first-generation cells will have a strong rejection reaction with the original body tissue.

The experimenter's vital signs were severely disrupted, and he eventually died and turned into a big tree.

However, Sasuke's words are much better, because he himself lives in the Eternal Mangekyo, although his strength is not as strong as Senju Hashirama at his peak.

But both the yin power and the yang power are at the same level.

Even if the first-generation cells were stronger than his current body cells, they still couldn't cope with the large amount of cells in Sasuke's body.

Therefore, for ordinary people, the first-generation experiment that narrowly escaped death did not pose much risk to Sasuke.

"Next, I will try to fuse the primary cells with my body's bone marrow cells..."

As he spoke, the eternal kaleidoscope in Sasuke's eyes slowly rotated, controlling the Yin Escape power of the Sharingan to slowly advance toward the spine through the meridians.

With the arrival of Sasuke's Yin Escape power, a delicate balance was reached with the Yang Escape power of the first-generation cells injected into his bone marrow cavity, and the two began to slowly merge.

Time passed slowly, Sasuke was carefully controlling the fusion of the two, while the shadow clone kept observing the instruments around the operating table, monitoring everything.

"Abnormal heartbeat and blood pressure return to normal..."

The shadow clone glanced at the instrument screen, recorded all the data in the document, and asked: "Did it succeed?"

Upon hearing the question, Sasuke slowly opened his eyes and said calmly: "It's considered a success."

At this time, all the discomfort in Sasuke's body had disappeared. He only felt extremely relaxed. An extremely relaxing and comfortable warmth filled his whole body. This wonderful feeling was simply difficult to describe.

To really describe it, it's like hiring the best technician in the ninja world to make a sauna for yourself.

"The first-generation cells have completely disappeared in my body, and have preliminary fusion with my own bone marrow cells, turning into my own bone marrow stem cells..."

"Yeah!" The shadow clone listened, recorded it, and continued: "Are there any obvious changes in the power of the pupils and the activity of the body?"

Sasuke shook his head and responded: "There is no obvious change. It can only be said that the physical activity and eye power have increased slightly."

"The new Sasuke cells generated by the fusion of the first-generation cells and my own cells only occupy an insignificant part of the cells in my body. They have no qualitative change in my current strength. They need to be continuously differentiated through the Sasuke cells as the source.

Replacing other cells throughout the body is a long process..."

The shadow clone nodded, not surprised.

Uchiha Madara bit off a piece of Senju Hashirama's flesh, cultured it and transplanted it to his body, growing a sweetheart on his body.

Strictly speaking, his reincarnation eye is the result of the fusion of his Yin Escape Power and the Yang Escape Power of that piece of meat, but except for that piece of meat, all his remaining organs, tissues, and cells are still his Uchiha Madara's.

.

rather than a fusion of the two.

Sasuke injected the first-generation cells into the bone marrow cavity. After the fusion, the self-replication and differentiation of the new embryonic stem cells made all organs, bones, nerves, and cells brand new from the inside out. This is true fusion.

However, Sasuke's method also has a slight disadvantage, that is, it takes a long time.

His newly generated Sasuke cells probably only number in the tens of thousands, and the average human body has about 40 trillion to 60 trillion cells.

And the number of human bodies in this world is even more special, there are 130 trillion!

It is almost equivalent to hundreds of thousands of times that of the human body in the previous life!

Don't ask, ask is Chakra!

It is bound to be a long process to replace the 130 trillion cells in the body with tens of thousands of new Sasuke cells.

In order to speed up this time, Sasuke must continuously inject first-generation cells and guide him through the power of escape for a long period of time.

"However, come to think of it, before all the cells in my body have turned into Sasuke's cells, I will already be qualified to awaken the Rinnegan."

Sasuke closed his eyes silently, exhaled a breath, and concluded.

The first-generation cells from the sweetheart's body that were on Uchiha Madara's chest accounted for five to six trillion of Uchiha Madara's 130 trillion.

Since Madara Uchiha could rely on the power of Yang Escape in his cells, he successfully awakened the Samsara Eye.

Although the activity of the auxiliary cells after fusion with the primary cells was much lower than that of the primary cells.

But when Sasuke has 20 trillion or 30 trillion, he should also be qualified to awaken the samsara eye, right?

That's what he said, but Sasuke also knew that the reincarnation eye is not so easy to awaken.

You must know that when Uchiha Madara transplanted the piece of flesh from the first generation, he was in his prime, and his own strength and mastery of the Sharingan were far superior to Sasuke now.

The fourth form of the Eyeless Kai, Susanoo, singled out the Nine Tailed Beasts and Gaara, the Fairy Fox Naruto.

Sasuke can only use his fourth form now, let alone fight the nine tailed beasts without eyes.

Even with his eyesight, Sasuke would say "Goodbye!"

Even though Uchiha Madara was so powerful, he did not awaken the Samsara Eye right away. Instead, he spent decades holding it in until the day he was about to die before awakening the Samsara Eye.

Obviously the reincarnation eye is not so easy to awaken.

I even wonder if there are other hidden factors besides the unity of all things.

For example, only when you experience the taste of death between life and death can you fully meet the conditions.

After all, the Eye of Reincarnation is the Eye of Creation, which is known as the ability to create the world, or it can also be the Eye of Destruction, which has the ability to destroy the world.

It represents life and death. Perhaps the power of yin and yang escape is not enough.

However, he will have to experiment with these in the future. His current goal is to speed up the production of more Sasuke cells.

"Are you going to inject Naruto's cells next?"

While Sasuke was deep in thought, the shadow clone beside him asked.

The shadow clone's question interrupted Sasuke's thinking. Sasuke raised his head and shook his head.

"No, I haven't figured out the brand-new cells yet. I'll talk about it after I figure it out."

He clenched his fists and sensed some changes in his body. Sasuke said solemnly: "Sasuke's current cells are too few and it has not made much difference to my strength. When he differentiates to a certain level, I can sense the body's

After there are clear changes, we can decide on the next experiment.”

The shadow clone nodded without saying much. After recording all the data on the document, he stepped forward and removed the various connections on the main body, and then released the shadow clone.

Sasuke put on his clothes again, found a chair to lean on, and closed his eyes to rest.

He was a little tired.
