"Kushina, is Naruto asleep?"
"Yes, that silly son of ours is fine now. Before he fell asleep, he was still clamoring to learn ninjutsu from you tomorrow."
Kushina noticed Namikaze Minato's still-unhealed arm and asked in confusion, "Minato, your arm..."
Namikaze Minato glanced at his arm in distress and then smiled, saying, "That guy's jutsu might have a problem; it disrupted the recovery of the Reanimation Body... but luckily I have one hand left to teach Naruto ninjutsu."
"I'll go find the Fifth Hokage tomorrow to ask about it; he should have a way, or perhaps reanimate again..."
Kushina spoke, doing it for Naruto. Otherwise, seeing Namikaze Minato with a missing arm might make Naruto feel bad.
"Thank you, Kushina... Lately, I've been troubling you a lot, in various ways, including Naruto!"
Namikaze Minato said, his expression a bit solemn, which made Kushina slightly uneasy.
Then Kushina waved her hand and said, "Isn't this what I should do, Minato? I'm Naruto's mother!"
Namikaze Minato chuckled, not speaking further. He had carefully considered before speaking; being left in the Ninja World had the possibility of resurrection, but the conditions must be very harsh, as he learned from Jiraiya-sensei.
Jiraiya-sensei told him that Lady Tsunade said it cost a great deal to resurrect Nawaki.
This price was something Namikaze Minato likely couldn't afford. Although Kushina was good friends with Uzumaki Minami, it wouldn't necessarily help with this matter.
So during his reflections earlier, Namikaze Minato had decided that after teaching Naruto ninjutsu, he would return to the Pure Land.
Even if there's the Reanimation Jutsu, the difference between the living and the dead is significant; he currently doesn't need to eat or sleep. Previously in the Hidden Sand Village, others rotated night shifts, while Namikaze Minato kept watch alone, lying in bed sleepless.
Short term was fine, but over time, Namikaze Minato felt he couldn't handle it.
However, Namikaze Minato didn't tell Kushina just yet, but planned to return to the Pure Land after teaching Naruto ninjutsu and fulfilling his final regrets.
The next day.
Tsunade, after questioning the Anbu about last night's events, also asked where Uchiha Yoichi was, then temporarily left Yoko with Shizune and came to Orochimaru.
"Did you stay up all night? Yoichi, you didn't rest either?"
Upon arrival, Tsunade saw Orochimaru still studying and dissecting specimens, and couldn't help but ask in surprise.
"There's no time to waste, Tsunade. This guy's recovery power is similar to your Strength of a Hundred Seal, and if Mr. Yoichi hadn't sealed him, I wouldn't dare study such a dangerous person so easily..."
Orochimaru's words were laced with complaint, but his face was full of vigor; he was willing to study such people, especially since the Otsutsuki Race was immortal.
They had enormous value.
"Is it really that exaggerated..."
When Tsunade saw Otsutsuki Urashiki's form, similar to a human, with limbs and neck pierced by Truth-Seeking Orbs turned into shackles, secured all around, and covered in sealing techniques, she could tell this person wasn't simple.
Otherwise, he wouldn't be treated so carefully.
Uchiha Yoichi asked, "Tsunade, where's Yoko?"
Tsunade answered, "Shizune is watching over her; does this guy need my help?"
Hearing this, Orochimaru smiled and said, "Certainly, but leave the preliminary work to me. Otherwise, Mr. Yoichi sure won't be pleased."
This was agreed last night; Orochimaru was responsible for dissecting Otsutsuki Urashiki's body and extracting samples before Tsunade conducted further research.
"Alright then, let the Anbu notify me when it's done."
Tsunade agreed, noting that the village's various sectors were rapidly developing, and her two grandfathers and Nawaki were completing various tasks; she couldn't rest much either, but because of Yoko, she could only do her best research work.
Even though Tsunade excelled at medical ninjutsu, there wasn't a large-scale injury event at the frontline, and the Uchiha Race's healing secret medicine was being sold cheaply to the village, ensuring many village ninjas had some.
When a large-scale war truly occurs, Tsunade, the princess among the Sannin, will undoubtedly show all enemies her immortal tactics.
"Orochimaru, since the Otsutsuki Urashiki won't escape, Tsunade and I will head back now."
Uchiha Yoichi spoke; he kept watch all night, and although Otsutsuki Urashiki briefly woke and struggled, he couldn't move anymore once two Yin-Yang Release Black Rods pierced his throat, pinning him to the experiment bed.
Up until now, Otsutsuki Urashiki remained completely immobilized.
"You two... never mind, I'll handle the rest."
Orochimaru said helplessly; he had originally expected Tsunade to help him, but now it seemed like a wasted expectation, as Tsunade not only did nothing but also took Uchiha Yoichi away.
After leaving Orochimaru, Uchiha Yoichi first accompanied Tsunade to check on Yoko; compared to his son, he indeed preferred his daughter more.
Especially since Yoko contained immense potential within, Uchiha Yoichi sealed some Genetic Primordial Energy inside her, allowing it to nourish Yoko as she grows.
Then, Uchiha Yoichi went to see Hyuga Satomi.
