Chapter 279

"Kushina, is Naruto asleep?"

"Yes, that silly son of ours is fine now. Before he fell asleep, he was still pestering about wanting to learn ninjutsu from you tomorrow."

Seeing that Minato's arm had not yet recovered, Kushina couldn't help but ask in confusion, "Minato, what happened to your arm?"

Upon hearing this, Minato looked at his arm with a troubled expression and then smiled as he said, "It seems like there's a problem with that guy's jutsu. It disrupted the recovery of my Edo Tensei body. But thankfully, I still have one hand left, so I can still teach Naruto ninjutsu."

"I'll go see the Fifth Hokage tomorrow. He should have a solution, or we can just re-summon the Edo Tensei," Kushina said. She was doing this for Naruto's sake—she didn't want him to feel bad seeing Minato missing an arm.

"Thank you, Kushina. Lately, you've been handling everything, especially taking care of Naruto," Minato said, his expression slightly solemn, which made Kushina feel a little uneasy.

Waving her hand, Kushina replied, "Isn't this what I'm supposed to do, Minato? I'm Naruto's mother!"

Minato smiled but didn't say anything further. He had thought it through carefully. Although staying in the shinobi world might offer a chance at being resurrected, the conditions would certainly be harsh. He had already learned this from Jiraiya-sensei.

Jiraiya had told him that Lady Tsunade paid a great price to resurrect Nawaki.

Minato likely couldn't afford such a price. Although Kushina and Mina were good friends, that probably wouldn't help in this case.

Therefore, after careful consideration, Minato had decided that once he finished teaching Naruto ninjutsu, he would return to the Pure Land.

Even with Edo Tensei, there was still a significant difference between the living and the dead. Now, he no longer needed to eat or sleep. During their time in Sunagakure, when others took shifts for guard duty, Minato could watch over the night alone, unable to sleep even when lying down.

In the short term, it wasn't too bad, but over time, Minato found it unbearable.

However, Minato did not share his thoughts with Kushina at this time. He planned to wait until after he had taught Naruto ninjutsu and fulfilled his final regret before returning to the Pure Land.

...

The next day.

After asking the Anbu about the events from the previous night, Tsunade also inquired about Yoichi's whereabouts and temporarily left Yoko in Shizune's care before heading over to Orochimaru's lab.

"Did you stay up all night? Yoichi, did you not rest either?" Tsunade asked in surprise when she arrived and saw Orochimaru still dissecting and researching.

"We couldn't afford to waste time, Tsunade. This guy's regenerative ability is probably on par with your Seal. If Yoichi-kun hadn't sealed him, I wouldn't dare research such a dangerous individual so casually."

Although Orochimaru's words carried a hint of complaint, he looked incredibly energetic; it was clear he enjoyed researching such individuals, especially someone like the Ōtsutsuki, a long-lived race.

They held immense value.

"Is it really that exaggerated?"

Tsunade glanced at Urashiki, who looked no different from a human except for the black rods made of Truth-Seeking Balls that pierced his limbs and neck, holding him in place. His body was also marked with sealing techniques, making it clear that he was no ordinary person.

Otherwise, they wouldn't have taken such precautions.

Yoichi asked, "Tsunade, where's Yoko?"

Tsunade replied, "Shizune is watching over her. Do you need my help with this guy?"

Orochimaru laughed and said, "Of course I do, but for now, I'll handle the preliminary work. Yoichi-kun probably wouldn't be happy otherwise."

This was what they had agreed upon the previous night—Orochimaru would dissect Urashiki's body and extract tissue samples, and once that was done, Tsunade could take over for further research.

"Alright, just let the Anbu notify me when you're ready," Tsunade nodded and said. The village was developing rapidly in all sectors, and her two grandfathers, along with Shizune, were completing various tasks. Tsunade barely had time to rest but still focused on her specialty—research.

Although Tsunade's greatest strength was medical ninjutsu, there hadn't been any large-scale injuries on the front lines recently. Moreover, the Uchiha clan's secret healing medicine was being sold cheaply to the village, allowing many shinobi to access it.

When a full-scale war eventually broke out, Tsunade, one of the legendary Sannin, would show the world her immortal battle tactics.

"Since Ōtsutsuki Urashiki won't be escaping, I'll take Tsunade back," Yoichi said. He had guarded Urashiki all night. Urashiki had briefly woken up and tried to struggle, but Yoichi had swiftly pierced his throat with two black rods, pinning him to the bed. Since then, Urashiki hadn't moved.

"Fine, leave the rest to me," Orochimaru said, slightly disappointed. He had hoped Tsunade would help him, but it seemed his hopes had been in vain. Not only had Tsunade not done much, but she had also taken Yoichi with her.

After leaving Orochimaru's lab, Yoichi accompanied Tsunade to check on Yoko. Compared to his son, Yoichi clearly favored his daughter more.

Especially since Yoko possessed immense potential. Yoichi decided to seal some of the primordial genes inside her, allowing these genes to nurture her growth as she matured.

Yoichi then went to visit Rumi, who had been taken to the hospital after almost fainting at the Hokage Tower due to her eyes.

"Sensei, you're here!"

When Rumi saw Yoichi, she immediately showed a sweet smile and asked with excitement, "Was there an enemy invasion last night?"

"Yes, but it has been resolved. How are your eyes?" Yoichi asked.

"They're great! I've never felt this good before!"

Rumi smiled as she removed the bandages from her eyes, revealing bright, sky-blue eyes.

"Your eyes have evolved very well, Rumi. They've become Tenseigan!"

Yoichi examined her eyes closely. The awakening of the Tenseigan was much easier than the Rinnegan, and though it lacked the wide range of abilities, its destructive power was formidable.

Due to her incomplete Byakugan, the evolution took longer than it would for someone from the Ōtsutsuki clan, but thanks to the removal of the Caged Bird Seal, the Tenseigan had successfully awakened.

"Let's go outside and test the abilities you've gained, Rumi," Yoichi said.

Rumi nodded in agreement. Using the Flying Thunder God Technique, Yoichi transported her to a remote, empty forest outside the village.

Once there, Yoichi said, "Rumi, show me the techniques you've acquired."

"Yes, Yoichi-sensei."

Even though she was still in her hospital gown, Rumi straightened her posture.

She quickly formed hand signs, gathering chakra. In a few seconds, a powerful aura emanated from her, with a green chakra aura surrounding her body.

The aura then transformed into a chakra cloak with tomoe markings. Behind her, three Truth-Seeking Balls floated, and her power had increased nearly tenfold.

At this moment, Yoichi felt that she might be stronger than Sakumo or Tobirama.

"Yoichi-sensei, this is the Tenseigan Chakra Mode, but I don't have enough chakra to use many of the ocular techniques."

Rumi raised her hand toward the empty forest ahead of them.

The three Truth-Seeking Balls spun rapidly in her hand, forming a faint green ball of light. Rumi then called out, "Silver Wheel Reincarnation Explosion!"

A violent and terrifying tornado erupted from her hand, obliterating the forest within a radius of several kilometers as if it had been struck by a natural disaster.

After a few minutes, the tornado subsided, leaving behind deep craters several meters wide where it had passed.

"This is just one of the techniques. I have another, even more powerful one, but I don't have enough chakra left to use it," Rumi said, breathing slightly heavily as she deactivated the Tenseigan Chakra Mode.

Before, without using Sage Mode or a curse mark, she had been somewhere between a jōnin and elite jōnin. With the curse mark, she could reliably reach elite jōnin level.

But in just a few days, she had awakened the Tenseigan. Though her eyes had evolved, her chakra had not increased yet. It would take time for her chakra to grow to match the new abilities.

"However, my chakra has recently been increasing again. I believe it won't be long before I can fully use the Tenseigan in battle, Yoichi-sensei," Rumi said, tilting her head with a playful smile as she moved closer to Yoichi.

The Tenseigan had unlocked her chakra limit. Before, elite jōnin was her maximum potential, but with the Tenseigan, that limit had increased tenfold.

"Rumi, I may need your help in the future. You'll also be responsible for controlling the Tenseigan Pillar in the village."

"I understand, Yoichi-sensei. If you need anything, I'll be there," Rumi nodded but then frowned slightly and added, "I've heard that the main family isn't entirely happy and may try to stir up trouble…"

"I'll leave that to you. I have other matters to attend to," Yoichi replied, habitually delegating tasks. With Rumi's current power, dealing with the main family wouldn't be difficult. She had surpassed the Kage level and could wield the power of the Tenseigan with the chakra Yoichi had left her.

Without the Caged Bird Seal and with the legacy of Hamura in her hands, handling a few members of the main family would be no problem.

After sending Rumi back, Yoichi went to his alchemy room. Having dealt with Ōtsutsuki Urashiki the previous day, he would be busy for some time.

He hadn't yet dealt with Urashiki's eyes, which were incredibly powerful. However, Yoichi's second clone was more interested in obtaining the Tenseigan.

He couldn't give up his Kamui Mangekyō Sharingan, and creating a third clone would be too much.

As for giving the eyes to someone else, the first person who came to mind was Tsunade, though Yoichi didn't know if she would accept someone else's eyes—especially a Rinnegan based on the Byakugan.

Aside from the Rinnegan, Yoichi's greatest gain from Urashiki was the treasure tool, the Karasuki.

After becoming Hokage, Yoichi had searched the village for this tool but couldn't find it, guessing it might be collected in the future. Now, to his surprise, Urashiki had brought it to him. Yoichi really should thank him.

"Karasuki, can you travel through time and space now?"

"Not enough energy. At the current rate, it will take another half a month—oh, wait, the energy is sufficient now!"

As the turtle-like tool spoke, Yoichi poured his own chakra into it, quickly replenishing the energy needed for time-space travel.

"I am Ōtsutsuki's treasure tool, the Karasuki, capable of taking people through time and space. Please be aware, however, not to travel to past events related to yourself."

The turtle gave some warnings about time travel.

Yoichi asked, "Can it only travel to the past? Not the future?"

"The future is uncertain. Traveling to the future would require five times the current energy, and the future you reach may not be reliable."

Yoichi continued, "If I'm now effectively immortal, but I travel to a timeline where I no longer exist, would that be a parallel universe or a timeline where I died unexpectedly?"

"…."

The turtle-like tool went silent, unable to answer. Seeing no response, Yoichi gave up on asking more complex questions.

This tool had limited intelligence, and only its creator could answer such deep questions.

However, time travel made Yoichi further realize the strength of the Ōtsutsuki clan. He had undergone many evolutions and still didn't possess space-time abilities, yet the Ōtsutsuki clan could create tools that allowed time travel.

"Would you like to travel now?"

"No need. You can rest for now. I'll wake you when I need you."

After putting the tool to sleep and storing it away, Uchiha Yoichi pondered.

Traveling to the past didn't seem very meaningful. Although the turtle said altering the past could change the present, Yoichi felt skeptical.

He had grown so strong—would a change in the past really cause his death?

Time travel was certainly fascinating, and Yoichi was determined to try it one day. However, with the shinobi world still in turmoil, with four nations allied against Konoha and Uchiha Madara lurking in the shadows, it was not the right time.

Once all these threats were resolved, Yoichi planned to travel both to the past and future.

In twenty years, the Kara organization would begin studying the corpse of the Ōtsutsuki God, a being capable of ascending dimensions. Yoichi's curiosity about this 'god' grew ever stronger.
