Cell Transplantation

"Medical ninjutsu? Who am I supposed to learn that from! Besides, that doesn't even make sense! It looks like I'll have to force a Copy!"

"But simple cell transplantation shouldn't be that complicated! The real trouble is that I only have one chance for a special fusion. After evolving into the Mangekyō Sharingan, there will definitely be a period of adjustment, so I'd better transplant the cells first!"

After a brief thought, Sasuke turned his gaze toward the Naruto cells in his storage and took them out.

This was the part of the storage system Sasuke found most unreasonable; whether it was the Mangekyō Sharingan or those cells, he had to perform the surgery himself. The system was only responsible for the fusion process after the transplant.

Sasuke felt a bit speechless about this. Fusing cells was simple enough—just make an incision, insert the cells, and let them fuse. Bloodline fusion worked the same way, but transplanting the Mangekyō Sharingan required some actual medical knowledge.

A lump of flesh radiating life force appeared in Sasuke's hand; this was the Naruto cell that Sasuke had reinforced through Shenlian.

Sasuke took out a Kunai, sliced a long wound on his right arm, and immediately placed the Naruto cells into the gash.

The moment the transplant began, Sasuke felt waves of pain coming from the wound. Clearly, his own cells did not welcome the arrival of Naruto's cells.

"If it weren't for the sake of getting stronger, I wouldn't like this either!" Enduring the pain, he opened the cell fusion panel and initiated the process.

As the fusion began, Sasuke clearly felt a mysterious energy enter his right arm. The pain vanished instantly, replaced by a warm, soothing sensation.

The warmth spread throughout his entire right arm and then rapidly diffused. In the blink of an eye, Sasuke felt his whole body heating up. Along with the heat came a sense of comfort so intense that he almost wanted to cry out.

A long time later, the fusion ended. Sasuke felt his Chakra reserves had increased significantly. If his Chakra had been a lake before, it was now an ocean—a qualitative leap.

After the fusion concluded, Sasuke suddenly noticed his skin slowly beginning to flake away. Pieces of dead skin fell in front of him, revealing brand-new skin underneath.

"Reborn?"

Looking at his skin, which was now even more supple than before, these four words slowly surfaced in his mind.

[Cell fusion successful. Obtained Primary Sage Body, Yang Release!]

Just as Sasuke was pondering the changes in his body, the system panel suddenly appeared before him.

"Hahahahahaha!" Looking at the system prompt, Sasuke couldn't help but laugh wildly. He had the Sage Body now; it seemed his theory was correct.

Once he gathered the Naruto cells, Senju Hashirama cells, Uzumaki bloodline, and Senju bloodline, he would likely possess the bloodline of Asura. Combined with the Indra bloodline he had awakened after absorbing the Uchiha Bloodline Crystal, fusing these two would grant him the bloodline of the Sage of Six Paths.

"This is truly great! Naruto, I have to thank you for this! Hahahaha!"

Feeling the improvement in all his physical abilities, Sasuke laughed maniacally before heading into the bathroom, as his body was still shedding old skin.

[Host: Sasuke]

[Bloodline: Uchiha]

[Cells: Original cells, Naruto cells]

[Kekkei Genkai Ninjutsu: Scorch Release, Storm Release]

[Kekkei Genkai: Sharingan, Sage Body]

[Chakra Level: Elite Jōnin]

After washing up, Sasuke sat on his bed and looked at his panel, feeling a bit stunned. It seemed the system panel changed along with his growth! After obtaining the Sage Body, the basic elemental releases were no longer displayed on the main panel, and a new one had appeared.

[Ninjutsu: Fire, Lightning, Wind, Water, Earth, Yin, Yang]

Opening the basic ninjutsu panel, Sasuke looked confused. Earth was something he had obtained by fusing a crystal, and Yang Release was just gained from absorbing the Naruto cells. What puzzled him was the Yin Release; this hadn't been displayed before.

"Are they Yin and Yang as one?" Looking at the newly appeared Yin Release, Sasuke eventually came up with a random theory and stopped worrying about it. After all, these were just basic ninjutsu; it was no big deal!

[Sage Body: Primary, possesses formidable vitality and surging Chakra!]

What Sasuke was really interested in was the newly acquired Kekkei Genkai, the Sage Body. However, after reading the description, he found it was just as expected—nothing to be surprised about.

"Regardless, I've truly become stronger!" Feeling the surging Chakra within his body, Sasuke took out a Kunai and sliced his finger.

Something unexpected happened: no blood flowed from the wound. Instead, a wisp of white mist emerged, and the wound began to heal slowly.

Five minutes later, his finger was as good as new. Sasuke shook his head helplessly; it seemed he was still a long way from the level of Senju Hashirama!

"No rush. Just wait a little longer, and I'll have Senju Hashirama's cells soon!" Recalling his plan, Sasuke drifted into a dream with a strange smile on his face.

The next morning, Sasuke still sent his Shadow Clone to meet up with Kakashi and the others. After all, the tasks they had been doing lately were definitely those low-value chores, and he felt a Shadow Clone was enough to handle them.

As for Sasuke's real body, he transformed into a different appearance and slowly entered the Konoha Library to look up the information he needed—specifically, information related to ophthalmology.

After all, when it came to something like an eye transplant, Sasuke believed it was more reliable to have a Shadow Clone perform it. He didn't trust anyone else.

When the Shadow Clone Sasuke arrived at the meeting spot on time, he saw Kakashi, who had arrived early for once, and Sakura, who was already waiting there.

"Good sense of time! Not a second late!" Seeing Sasuke arrive, Kakashi checked the time and curled his lip helplessly.

"Of course, I'm not the type to be late!" Giving a casual explanation, Sasuke stood to the side and began to wait. After all, the dead-last who always gave him such a good harvest hadn't arrived yet.

Soon, Asuma arrived with Shikamaru, Choji, and Ino to pick up their mission and leave. During this time, Shikamaru and the others looked at Sasuke and Sakura with some sympathy; being on a team with that king of tardiness was a tragedy.

After Team 10 left, Team 8, led by Kurenai, also finished picking up their mission and departed. The three of them were subjected to more mockery.

Cell transplant, Sage Body, the king of tardiness Naruto!
