"....No need!"
Hatake Sakumo learned quickly. After handing the work over to him, he skipped out of the office, which made Uchiha Yoichi angry. He even thought about dragging Kakashi over to work overtime, so that Hatake Sakumo would go home to an empty nest.
But on second thought, he decided against it. As the Hokage Assistant, he could make Kakashi work overtime, but then Hatake Sakumo might use his authority as Hokage to give Kakashi a break, and then say to Uchiha Yoichi, "Mr. Yoichi, I am the Hokage!"
Uchiha Yoichi decided to visit Konoha Hospital to check things out, as it was the second day since Tsunade returned. He wanted to see if there was anything needed.
Arriving at Konoha Hospital.
Uchiha Yoichi walked through the main entrance and greeted a few people before heading straight to the office on the top floor, which Tsunade used before she left and hadn't been used since.
"Come in."
After knocking and receiving permission from inside, Uchiha Yoichi pushed the door open and found Tsunade sitting on the sofa.
She looked completely unbothered by work, presenting a stark contrast to when Uchiha Yoichi used two clones and his real self to painstakingly handle documents.
"Why are you here, you shy little ghost?"
Tsunade's face lit up with joy upon seeing Uchiha Yoichi. Although she was about to stand up, she was pulled into his embrace as he walked over.
"I've wrapped up today's tasks for now. I saw your application, so I came to ask if there's anything you need."
After holding Tsunade in his arms, Uchiha Yoichi's hands began to wander; her soft and beautiful physique, along with her faint fragrance, made his hands uncontrollable with such an alluring woman in his arms.
"Mm~"
Tsunade let out a muffled groan as her sensitive areas were teased, rolled her eyes, and said, "You're such a brat, always up to no good.... Those devices are meant for researching the Desperate Virus. After scrutinizing it for a while, I feel it's something that alters the brain, quite fascinating.... Mm~"
"I trust your abilities, Tsunade. If the Desperate Virus can be realized in the Ninja World, only you could make that happen...."
Uchiha Yoichi doesn't doubt Tsunade's ability. She already has the raw data, and Medical Ninjutsu can make up for the equipment's shortcomings. The Desperate Virus research, entrusted to Tsunade, is bound to succeed.
Genetic Primordial Energy is harder to grasp; apart from him, others find it difficult to cultivate Genetic Primordial Energy. Once Tsunade perfects the Desperate Virus, the focus can shift to Genetic Primordial Energy.
Uchiha Yoichi hasn't slackened off either, having accumulated enough for two draws within the year and an extra one from before, redeeming it for one and a half months of the "Research Assistant".
This skill is meant to help him merge the World-Ending Spear Technique with his known Nin-Taijutsu. Within the year, Uchiha Yoichi used clones to train the World-Ending Spear Technique, reaching the fourth layer, with a maximum burst of 4.5 times.
The Wood Clone tactically scales the training needs of Nin-Taijutsu techniques; twenty clones training daily equates to ten years of training within a single year for Uchiha Yoichi.
The World-Ending Spear Technique becomes tougher as you advance, and some techniques don't suit him entirely, so Uchiha Yoichi desires to adapt them through his skills.
Combining the World-Ending Spear Technique and Lightning Release Chakra Mode requires "Research Assistant" for forty-five days.
Combining the World-Ending Spear Technique and Monster Strength requires "Research Assistant" for forty-one days.
Combining the World-Ending Spear Technique, Monster Strength, and Lightning Release Chakra Mode needs "Research Assistant" for sixty-nine days. Adding Rokushiki and Armament Aura extends the duration to one hundred eighty-nine days.
Considering everything, Uchiha Yoichi decided to only merge World-Ending, Monster Strength, and Lightning Release Chakra Mode; he already has forty-five days of "Research Assistant" available and only requires accumulating nine months of draw chances to develop the new Nin-Taijutsu.
"Research Assistant" offers three slots, enabling simultaneous research of two other merged Nin-Taijutsu techniques.
He stayed in Tsunade's office for over two hours.
The whole time, Tsunade kept groaning and mumbling softly before Uchiha Yoichi discovered she hadn't eaten yet, so he prepared creamy milk for her, which almost choked Tsunade, who angrily pushed him out.
After stepping out, Uchiha Yoichi noticed the sky was darkening and started heading home.
However, as he was going downstairs, he unexpectedly ran into Nohara Rin.
Upon seeing Uchiha Yoichi, Nohara Rin grinned sweetly and greeted him, "Teacher Yoichi, what brings you to Konoha Hospital?"
"Just discussing some matters with Tsunade. Rin, how is your learning going lately? Do you need any help from your teacher?"
Uchiha Yoichi also inquired, aware that he hadn't been as attentive to Nohara Rin, knowing only that she's studying at Konoha Hospital, but unsure of her progress.
"Not much, recently I've passed the assessment and become a Medical Jonin, learning a lot under Teacher Minami."
With her hands behind her back, Nohara Rin smiled and, after a moment's blush, approached Uchiha Yoichi, saying, "Teacher Yoichi, my Medical Ninjutsu has improved quite a bit lately. Would you like me to give you a massage.... Being the Hokage Assistant, you must be exhausted?"
"Um...."
Uchiha Yoichi honestly doesn't feel very tired, and Minami often uses the same trick to give him massages.
But, he didn't want to reject the student's goodwill, so he replied, "Now? Maybe another day, I need to head home soon..."
