Reborn into Naruto World with Tenseigan

With his back to the only source of light in the room, Kuroto looked at the syringe in his hand, and gently flicked it, causing the trapped air bubbles trapped within the needle tube to rise to the top, then with a firm grip, he pressed the plunger slightly, forcing the bubbles out of the syringe until only the clear fusion fluid remained inside it.

As Kuroto carried out the preparation, Shinichi strained to speak weakly, “Boss, please don’t make such sounds… it’s really scaring the shit out of me!”

“Shut up!” Kuroto reprimanded Shinichi in annoyance. Up until now, Kuroto did not realize that this reckless and carefree Uchiha is so afraid of medical equipment and operation.

Compared to Shinichi, Itachi was much better. He lay silently and adjusted his mood without caring about what was happening around him.

Outside the Underground Laboratory, Shisui is watching; inside the operation room, Kuroto and Samsara are present. In the presence of these people–at least Kuroto and Shisui–Itachi can drop his guards and disguises, and fully concentrate on mentally preparing himself to suppress and fuse the Hashirama Cells.

It did not take long, soon, Kuroto was done with all the preparations, and with the help of Samsara, he connected the equipment to Itachi and Shinichi so that he could have a real-time display of their physical data while the two underwent implantation operation. At the same time, Kuroto started explaining the procedure to the two Uchiha, “Firstly, I will inject this Fusion Solution into both of you, then, while the fusion solution takes effect, I will inject a small batch of the most active cells of Shodaime-sama in your body.” He paused for a while and added, “Keep in mind that the fusion solution will stay effective for only the first couple of minutes. Therefore, these first couple of minutes are the best time for the two of you to suppress those cells and initiate fusion. Right timing must be grasped.”

“Okay,” nodded Shinichi and asked cautiously, “What if… what happens if we fail to suppress the implanted cells within that time?”

Kuroto shrugged, “The attempt will fail, and we will have to start over.”

Shinichi nodded nervously, “Under… Understood!”

Noting Shinichi’s nervousness, and seeing that even Itachi was a little pressured, Kuroto decided to once again address this issue, “You both don’t have to worry that much. In fact, failure is pretty normal and nothing to be afraid of. As long as the two of us are here, nothing will happen to the two of you.”

After reassuring them, Kuroto decided not to delay anymore and immediately started the operation.

Before Shinichi and Itachi even realized it, the fusion solution was already injected into their bloodstreams.

“Now the two of you will feel your blood capillaries swelling which will cause pain, and a rapid increase in the heartbeat is natural as the blood flow will increase, of course, sweating and these things will also happen but don’t worry, these abnormal reactions are the sign of the presence of fusion fluid in your arteries.”

“Remember, only your Mangekyou Sharingan can suppress Shodaime-sama’s cells and initiate fusion with them.”

“Don’t worry about the loss of Visual Prowess, even if both of you have lost much of Visual Prowess, it’s not that important at the moment, what’s important is the Yin-Chakra… the process of suppression and fusion with Shodaime-sama’s cells is the fusion of Yin chakra in your body with the Yang chakra in those cells.”

As per Kuroto’s instructions, Itachi and Shinichi activated their Mangekyou Sharingan.

Looking at the different patterns in Shinichi and Itachi’s eyes, Samsara was amazed. Although Kuroto transplanted two different Eternal Mangekyou Sharingan, she never used their powers, therefore, she was really amazed to see these eyes in use.

While Samsara was busy admiring Itachi’s and Shinichi’s eyes, Kuroto injected the carefully processed Hashirama cells into their bodies.

As soon as the cells entered their body, both Shinichi and Itachi shouted in pain, “Ahhhhh!” “Arghhh!”

Being trained shinobi, both Itachi and Shinichi have excellent tolerance towards pain, be that as it may, when the Hashirama cells entered their body, neither of them could resist the tearing pain and cried out. This just goes to show how much pain the two Uchiha are suffering from at this moment. If not for the fact that their hands and feet were tied up, both of them would be rolling over the operation table.

Samsara was startled by their sudden screams and subconsciously stepped back, “This

Kuroto stood, quietly watching the two Uchiha with a serious expression as time passed second by second.

One minute…

Five minutes…

Ten minutes…

Thirty minutes…

In the blink of an eye, half an hour had already passed.

The fusion fluid will remain effective only for half an hour, that time has passed, yet Itachi and Shinichi were screaming intermittently as if they had lost their mind and will. R

Finally, she couldn’t take it, and asked in a worried tone, “Kuroto-sama, are they… are they going to be okay? Should I…?”

Kuroto shook his head, “Wait for a while, I will tell you when to help them.”

“Okay.” Nodded Samsara and quietly stood beside him. Waiting for Kuroto’s instructions.

After a few more minutes passed, Kuroto’s brows tightened. With his Tenseigan, he saw signs of Hashirama Cells running amok in Itachi’s body, immediately, he instructed Karin, “Hurry, absorb some Yang Chakra from his body.”

Samsara immediately pressed her left hand on Itachi’s chest, and with the help of Rinnegan's ability to absorb chakra, she started to suck out the Yang Chakra from his body, until Kuroto instructed her to stop.

Before Samsara had any time to take a deep breath, signs of Yang chakra running amok appeared in Shinichi’s body. Seeing this, Kuroto immediately, instructed her, “Hurry up… absorb from his body as well.”

She is inexperienced in tackling such emergencies, she panicked and hurriedly put her other hand on Shinichi’s chest and started to suck out the raging Yang chakra from his body.

While Itachi and Shinichi’s pain eased, Kuroto’s brows tightened, and he made a decision, “It seems I have to help them.”

Immediately he reached out and pressed his hands on Itachi and Shinichi’s foreheads, and activated his Tenseigan’s power to dive inside their consciousness.

Entering their consciousness plane, Kuroto looked at the two exhausted people, and asked indifferently, “Is this everything you got?”
