Reborn Into Naruto World With Tenseigan
The Road to Rinnegan


The next morning.


Both Shisui and Itachi came to the Deathly Forest as per Kuroto's instructions.


They search for Kuroto, and soon find her asleep on a tree branch, Shisui sees Kuroto's sleeping posture and suddenly gets an idea.


Shisui gestured for Itachi not to make a sound as he took out the Calligraphy Brush from his pocket.


Itachi wanted to talk to Shisui that this was not a good idea, but seeing how Shisui looked, Itachi chose to remain silent.


Now with the Calligraphy brush in her hand, Shisui took a silent cat step towards Kuroto, making sure that she did not make any sound so that she did not wake Kuroto up, making sure that she did not make any sound, and before long he stood in front of the sleeping Kuroto.


Now standing in front of Kuroto, Shisui moved her free hand to and fro, to make sure that Kuroto was actually sleeping.


After making sure that Kuroto was indeed asleep, Shisui sneered and without waiting, she raised her hand to put a nice touch of art on Kuroto's face.


Shisui gestured to Itachi again to make sure that he did not make any sound, while bringing the brush closer to Kuroto's face, and just as he turned towards Kuroto; Shisui noticed that Kuroto's eyes were wide open and Kuroto looked at her with a flat expression, "Shisui, what do you think you're doing?"


Shisui's hand stopped halfway, and she blinked twice to realize the situation, sweat pouring from her face and she jumped back in panic, "Kuroto-San, you're awake!!!?" Then while trying to hide the brush in a panic he said, “I... I think you are sleeping... and..”.


Itachi sighed, "I know this is a bad idea."


Kuroto yawned and stood up, after stretching her body to relieve all the drowsiness, Kuroto said to Shisui, "It's still morning and you're already very excited."


Shisui nodded, “Y... yes, today is very crowded, right?” just to make sure that Kuroto doesn't pursue the matter before.


And of course, Kuroto doesn't chase after him, Shisui is nervous, Kuroto can see that, and if a little humor and jokes can help Shisui calm his nerves then everything is fine with him.


"By the way, putting aside your childish antics, I hope you are ready for implantation surgery" Kuroto told Shisui.


At the mention of the operation, Shisui's face turned serious, and he nodded, "Yes."


Kuroto nodded and jumped down from the tree, and started weaving signatures.


Shisui also jumped up, and seeing the hand seal Kuroto had woven in front of the tree, she asked in a confused tone, "By the way, Kuroto-san, why call us to the Forest of Death?"


Kuroto answered Shisui's doubts, “Oplantation operation can not be done in your house or my house, it will be too risky, therefore we will do it here.”


"Here?" Shisui muttered.


Kuroto nodded, “This is my Secret Laboratory, but since we obtained Ancor Vantian, so I moved the Laboratory to the Sky Fortress, but it was still a secret hiding place because this place was never found by anyone because of how cleverly it was hidden. The perfect place to perform operations while staying in the village.”


Itachi raised his eyebrows after hearing Kuroto's words.


He still remembered that the Genin Team he was following had once had a mission to kill the extremely dangerous and ferocious Wild Boar that was interfering with the Food Chain in the Deathly Forest because of how much it ate, he said, and Itachi remembered that Kuroto happened to be present here at that time, and took responsibility for taking care of the Forest Pig.


Back then, Itachi did not think too much about it, as it was not strange for a Konoha Shinobi to be present in the Deathly Forest, after all, this place was not just a place to conduct the Chunin Promotion Test, after all, but it is also a training ground that is often used by many shinobi.


Not to mention, this place was also used to obtain ingredients to brew poison and other medicines.


And now that he heard about the Secret Laboratory, Itachi inevitably thought, 'It seems that it is not just a coincidence that we met Kuroto-san back then, Kuroto-san has set up a secret hiding place here. '


At this moment, the entrance inside the tree opened, and Kuroto walked in followed by Shisui behind him, before the two entered completely, Kuroto said to Itachi, "Itachi-kun, I'm sure you're going to get there, the implantation operation may take several hours, during this time, neither I nor Shisui will be in any condition to help, so please guard the entrance and make sure nothing interferes. ”


Itachi nodded politely, "I understand Kuroto-san, please make sure the operation is successful, you don't have to worry about anything interfering."


Kuroto nodded, "Hmm." Then start walking deeper into the lab.


And just as Shisui was about to follow Kuroto, Itachi said to him, "Be careful Shisui-san."


Shisui turned around and asked with a grin, "What do I see here Itachi, are you worried about me?"


Itachi did not nod or deny.


Shisui simply smiled and waved his hand, "Don't be afraid of my friend, I will win this battle, and defeat the death mistress before she can take my heart."


'She is incredibly poetic and funny, this is not like Shisui-san, no doubt, Shisui-san is indeed nervous about what will happen.' Itachi thought as he looked at Shisui and Kuroto's faded backs and the entrance to the hideout was closed.


And with Kuroto and Shisui gone, Itachi jumped over the tree and sat there watching the surroundings, at the same time he spread his crow to help him keep an eye on the surroundings.


It didn't take long and the entire Deathly Forest was already under his watch.



Inside the Secret Laboratory.


While walking through the hallway illuminated with some fluorescent lights, Shisui's mind was filled with various thoughts.


Just from once seeing how deep the passageway was, Shisui could not help but sigh, "I never expected that the Secret Laboratory you have here would be so big Kuroto-san."


Shisui's eyesight might have almost deteriorated, he could still see and feel things, after all, his perception was still very good.


Kuroto while walking in front nodded indifferently, "Nothing is strange."


“Is it really?” Shisui sighed softly.


This operating room has been neatly reorganized by Kuroto, all for the purpose of implantation surgery. A lot of money is spent by Kuroto to make sure all the instruments are present.


Looking at the various medical instruments in the operating room, Shisui was astonished, “Kuroto-san, isn't this just an implantation operation? What is needed for so many instruments, they make me more nervous.”


Kuroto gestured for Shisui to get down to the bed and began to explain, “There's nothing to worry about, these instruments are placed here to keep your vital signs real-time during implantation surgery.


There is Cardiac Meter to measure heart rate, Pulse Oximeter to keep the Pulse under control, then there is Respirometer as well as oxygen supplier, Blood Pressure Monitor to measure your Blood Pressure, in addition, there is a thermometer, there is a, a body water level meter and some other devices.


Obviously, all this is not necessary, but I have arranged it to make sure everything goes unimpeded.”


Shisui nodded.


At this time, Kuroto took out an injection, added some medicine into it, then injected it directly into Shisui's bloodstream, while explaining, “This is an intravenous injection, he said, and the liquid it contains is a strong cell mover. For successful cell implantation, cell activator is required.”.


“Cell activator, right?” Shisui muttered as he suddenly started to feel something in his bloodstream and his entire circulatory system.


After injecting the liquid completely, Kuroto threw the injection into the trash, and said, "It will take about 2 to 5 minutes to get the full effect, meanwhile, change your clothes to patient's."



5 Minutes later.


Shisui did as he was told, and after changing into the patient's clothes, he was currently lying on a bed made of stone.


After preparing a few other things, Kuroto said to Shisui, "Now almost everything is ready, let me introduce the complete procedure first to you."


Shisui nodded with a puzzled expression as the cell activator given made him feel so hot, so hot that even though this surgery lab was so cold, Shisui still sweated a lot.


Kuroto said, “On the First Step, I will remove your Mangekyou Sharingan and replace it with a pair of Mangekyou Eternal Sharingan.”.


The confused Shisui initially nodded, but in the next moment, he realized what Kuroto had said and immediately sat down in surprise, “What!? Butwhy? This is a Cell Planting Operation, so why the eye?”


Kuroto patiently explained, "Your eyes are completely blind, so I'm worried that with the current Strength of your Eyes, you won't be able to suppress Shodaime-sama's Cell, so to make sure there is nothing wrong, either, I'll embed the Eternal Mangekyou Sharingan."


Shisui asked, “But will Tsukihi agree to it? After all, the Eternal Mangekyou Sharingan was already inside her.”.


Tuk…


Shisui had not even finished speaking, and Kuruto had already placed the small Nutrient Capsule on the table beside him.


Shisui looked at the Nutrient Capsule and saw a pair of eyes hovering inside the glass capsule, and he did not know what to talk about anymore.


Kuroto patted Shisui on the shoulder and gestured for her to lie down, saying, “Don't worry, Uchiha Tsukihi is a selfless girl and she happily notices you, actually, Uchiha Tsukihi, knowing that your surgery was about to be performed. Out, he approached me of his own volition and gave me the idea to use these eyes. To make sure that you survive. ”


Shisui said sincerely, "Kuroto-san if I don't survive, please accept that he's replacing me for everything he's done and done for the Uchiha Clan."


“I'd rather not, do it yourself. Which means you're not allowed to die. ” After the pause here, Kuroto explained the next step, “So after your eyes are replaced in the first step, for the second step I will inject Fusion Solution into your body. The Fusion Solution is made of some special drugs and will cause you a little pain, but you have to endure the pain as this is necessary for the success of implantation.”


“After the first two steps, we will have the third step, in which case I will inject Shodaime-sama Cells specially treated into your body, all you have to do is use your own eye power to suppress it and make sure that they do not take it. Over your body completely otherwise, it means death by becoming a tree,” explained Kuroto.


Shisui nodded, "Alright."


Kuroto added, “One thing I want you to remember is that I will not use any anesthetic agent in the entire implantation operation so that you can fully use the Strength of Your Eyes and feel the changes taking place in your Body. So, remember that the pain you feel will be overwhelming. It would be so unbearable that you would rather die. But you have to endure.”


Shisui nodded, understanding what Kuroto meant here. Shinobi are trained to endure pain. Cuts, cuts, fractures, muscle tears, and other types of pain can be easily ascertained by them and there is no need to even mention those things. So, the fact that Kuroto mentioned it and emphasized the term 'extraordinary pain' definitely meant that her pain would be higher than she could bear as a trained shinobi, but she had to endure it, and not only does he have to defend, he has to win over him. Kuroto tells him about this beforehand to make Shisui prepare herself psychologically.


"Yes." Yeah." Shisui nodded, he was very confident in the limits of his pain tolerance.


Finally, Kuroto said in a deep voice to make sure that Shisui paid attention to his words, “Remember that Hashirama Cells are more cancerous than any type of tumor, though, and they take over their targets very quickly, faster than the human mind can. Some time ago, I managed to get experimental data from experiments and Hashirama Cell Implantation surgery performed by the village. All records show that no matter how strong one's will was, in the presence of Hashirama's Cell, he was unable to endure.


Dementia, Hypersalivation, Hyperhidrosis, temporary failure of sensory nerves, Urinary incontinence due to loss of control over the bladder, and Fecal Incontinence due to loss of bowel control, are some of the things that you will experience besides pain, there is also a possibility that you will turn into a half-human, half-tree creature if you do not pay attention. So be careful.”


Shisui heard Kuroto's words, and asked with a puzzled expression, "Uh.... is that why you told me not to drink water or food for these past two days?"


Kuroto nodded, "Yes, so anyway, what I mean is be careful, ahead is a life and death battle."


Shisui asked again, "But are you not saying that the success rate is one hundred percent?"


Kuroto nodded, "Indeed, as long as you can preserve it, if you yourself can't defend and give up, then there's nothing I can do about it."


Shisui fell silent and after taking a deep breath, he nodded, “Alright, there is too much I have to protect, I will never be able to forgive myself if I die on the operating table, so death is not even an option here. ”


After understanding Kuroto's words, Shisui let go of all the fear, nervousness, and anxiety, and his expression returned calm and serene as if he was present on the battlefield.


Kuroto sees Shisui quietly lying on the operating table, and without waiting any longer, she starts with implantation surgery.


Kuroto's intention to replace Shisui's eyes while performing Implantation Surgery was not just to increase the success rate of the surgery, but to improve the success rate of the surgery, but also to increase the Eternal Sharingan Mangekyou Eye Power with the help of the Yang Chakra present in Hashirama Cells in an attempt to develop the Eternal Mangekyou Sharingan into a Rinnegan.
