And then, finally, it was done. With a sense of satisfaction that bordered on euphoria, Jiro beheld his creation in all its glory: a fully functional arm crafted from the combined DNA of himself and his summoned leeches.

But even as he marveled at the success of his endeavor, Jiro knew that the true test lay in putting the arm to the test. With a sense of anticipation coursing through him, he created a hand seal to create a leech clone of himself. This clone would utilize Fumonnifusu Teate [To Disregard Treatment] allowing Jiro to focus on the part that required a bit more finesse, cutting his own arm off at the shoulder to replace it with this new limb.

Once the limb was in place, Jiro would take a moment to test out its motor function and make sure that everything was in order. Jiro knew that he had achieved something truly remarkable, but when it was all said and done, he still needed to make one more arm. With his creation, he had pushed the boundaries of medical science to new heights, unlocking the secrets of life itself and potentially advancing his understanding of DNA itself. As he gazed upon his creation with a sense of pride and wonder, he knew that the journey was far from over, for there were still a second arm to make.

[Tokuzō Jiro]

Now that Jiro had completed both the fabrication and attachment of the first arm, a sense of accomplishment surged through him, but his work was far from over. Without much hesitation, and perhaps a little overconfidence in his work, he'd toss the arm he was born with into a medical waste bin. With a determined gleam in his eyes, he turned his attention to the next phase of his experiment: the creation of a second arm, this time utilizing his medical ninjutsu to fashion the limb from a DNA sample.

With the combined DNA sample as his foundation, Jiro began the intricate process of molding the arm using his mastery of medical ninjutsu. Drawing upon his extensive knowledge of anatomy and physiology, he visualized the structure of the limb in his mind's eye, meticulously crafting each component with painstaking precision.

[Tokuzō Jiro]

But even as the arm began to coalesce, Jiro knew that while the true challenge lay in creating the first limb that was already attached, there was still the opportunity in new error that might occur when attempting to replicate the process. There was always the chance that the dna was unstable. .

As chakra slowly flowed into the limb in front of him, the arm pulsed with a faint glow, a testament to the power that coursed through its veins. And then, finally, it was done. With a sense of satisfaction that bordered on euphoria, Jiro beheld his creation in all its glory: a fully functional arm crafted from dna that he had created by merging dna from himself and the leeches that he worked with.

But even as he marveled at the success of his endeavor, Jiro knew that the final challenge lay in cutting his old arm off and replacing it with this one. With a sense of anticipation coursing through him, Jiro would take a deep breath in preparation for the endeavor he was about to undertake. Despite it being a process he was wholly familiar with and something he'd done for his patients hundreds of times, he was still a little uneasy doing it on himself.

It would be a lot easier if he could trust another shinobi to attach the arms, but given his nature Jiro didn't feel he could trust another medic with the process that was utilized to create them. With that in mind, his only real help that he'd get for this process was a copy of himself made of leeches.

[Tokuzō Jiro]

With the completion of the second arm, Jiro stood before his workbench, a sense of anticipation coursing through him as he prepared to replace his old limb with the new creation. With steady hands, he waited for his clone to stand behind him and perform Fumonnifusu Teate [To Disregard Treatment] to help reduce the pain

With a deep breath, Jiro flexed his fingers, marveling at the fluidity and precision of movement afforded by the new limb. Each motion felt natural and effortless, as if the arm had always been a part of him.

As he gazed upon his reflection in the polished surface of the workbench, Jiro couldn't help but feel a sense of gratitude for the journey that had brought him to this moment. With his new arm in place, he felt a renewed sense of purpose, ready to face whatever challenges lay ahead with confidence and determination.

And as he stepped away from the workbench, Jiro knew that he had taken another significant step forward in his quest for understanding. With his new arm by his side, he was ready to continue pushing the boundaries of medical science, unlocking the secrets of life itself one discovery at a time.

[Tokuzō Jiro]

As Jiro completed the intricate process of replacing his old arms with the new creations he had crafted, he knew that the true test lay in ensuring that the limbs functioned as expected. With the arms securely in place, he turned his attention to the next phase of his experiment: healing and integrating the new appendages with his body.

Seated before his workstation, Jiro utilized Shousen Jutsu - [Mystical Palm Technique] with the aid of his clone in order to make sure the arms were connected completely and healed. With his free arm he would begin booting up software that would help him time the reflexive response time of the muscles in his arm. This would allow him to know that the reflexes of the muscles in his arms were working as intended

As the machinery hummed to life, Jiro felt a surge of anticipation course through him, his eyes fixed on the monitors that displayed timers that would tell him how long it took his arms to respond to stimuli. In addition to the healing process, Jiro set up a series of electrodes connected to the monitors, intending to time his reflexive response to shocks. This would provide valuable data on the responsiveness and integration of the new limbs with his neural pathways.

[Tokuzō Jiro]

As the machinery hummed Jiro watched the screen with anticipation. With each passing moment, he monitored the data with meticulous attention to detail, ensuring that the arms were healing properly and that no complications arose. Meanwhile, the electrodes delivered controlled shocks to his new limbs, eliciting reflexive responses that were recorded and analyzed in real-time.

With each passing moment, he felt a growing sense of satisfaction as the monitors displayed the gradual improvement in the condition of his new limbs, while the data from the electrodes provided valuable insights into their responsiveness and integration with his nervous system.

Now that the numbers on screen confirmed what he had already suspected, Jiro knew that next he would need to determine that the connection was proper and he had a full range of motion. He flexed his fingers and tested the range of motion of each limb, while the electrodes continued to deliver controlled shocks to assess his reflexive responses. As he moved his arms a sense of relief flowed through him, slowly he was comforted to find that his new arms were performing just as his old arms had with the same tests.

With each motion, Jiro felt a sense of wonder and awe at his own medical capabilities. The movements were smooth and natural, as if the limbs had always been a part of him. As he continued to test their functionality, he marveled at the intricacies of their design and the precision with which they had been crafted.

[Tokuzō Jiro]

With his new arms securely integrated and functioning as expected, Jiro turned his attention to the final phase of the tests that he'd planned to conduct: testing the chakra network of the limbs. Seated before his workstation, he activated the specialized equipment designed to measure the lifting strength of something like tree climbing.

As the machinery hummed to life, Jiro focused his chakra, channeling it into the limbs with careful control. The machine wouldn't be able to directly measure anything regarding chakra levels, but it would be able to determine how much he could lift utilizing just the tree climbing jutsu. He'd place each hand on the machine, flow chakra into his hands and lift with all of his might.

As Jiro lifted with each hand, he monitored the data displayed on the screens before him, analyzing the relative strength of each arm and how it compared to the data of the tests he'd done the day prior. With each passing moment, he observed the subtle fluctuations. There were small differences, but it was likely that those were largely caused by the fact that he had utilized a ton of chakra to attach and create the arms. It was something that he hadn't accounted for orginally, but it was a satisfactory explanation for the time being.

[Tokuzō Jiro]

After the rigorous testing of his new arms, Jiro dispelled the clone he had created to assist him in the laboratory. With a wave of his hand, the clone dissipated into a cloud of smoke, leaving behind a sense of emptiness in the room.

With a sigh of relief, Jiro stretched his arms and rolled his shoulders, feeling the tension of the day slowly dissipating. As he stood amidst the quiet solitude of the laboratory, he couldn't help but feel a sense of satisfaction at the success of his experiment.

He would spend his final moments in his secret labratory disposing of the biological waste that was his old arms and wrapping his new arms in bandages to hide their new blackened coloration. Luckily he had started wrapping his arms a while back when he had thought of this idea, so it was unlikely that anyone would really question it now.

But even as he reveled in his accomplishments, Jiro could almost feel the ache that came with sitting in a single position for hours on end. With a weary smile, he made his way back up the stairs and back to his office, the familiar corridors of the hospital greeting him like an old friend.
