Let Naruto Have Both Parents

Shamu's mind flashed with the figures of Hashirama, Mito Uzumaki, Tobirama, Hatake Sakumo, and Kushina Uzumaki.

Then he glanced at his Path of Evolution.

Soul Strength 53%
Spatial Perception 37%
Vitality 50%
Energy Storage 27%
Reflexes 82%

There was nothing he could do about Spatial Perception, but for Vitality and Energy Storage, Hashirama's constitution and the Uzumaki Clan's constitution would undoubtedly be the most effective.

Hashirama's body was still being enhanced, so Tobirama was worth considering.

However, Tobirama's personality was difficult to control. If he were revived, there was a high chance he could not be recruited.

After all, it would be difficult to make someone who constantly talked about "evil Uchiha" submit.

Mito had died of old age. Without suitable sacrificial material that had been enhanced, she could not be restored to a younger body.

That only left Kushina.

It just so happened that he had once promised to let Naruto have both parents.

"Let's choose Kushina. We're only conducting an experiment anyway, and it isn't Kushina's first time coming back."

Orochimaru did not object. As a researcher, if it succeeded once, there would be more chances in the future.

If it could not even succeed the first time, then it did not matter who they chose.

"I don't know how long I can maintain the Spirit Transformation Technique this time. Let's begin immediately," Shamu urged.

"Good thing we prepared everything in advance."

Orochimaru muttered and headed outside.

Shamu controlled Urashiki's body and followed after him.

Naruto and Sasuke were already asleep outside. Indra and Asura had left their bodies.

In addition to extracting their souls, some Chakra and Mental Energy had also been drawn out.

As a result, Naruto and Sasuke had fallen into a deep sleep.

Tsunade and Dan Katō were standing guard beside Shamu's body. When Tsunade saw Urashiki behind Orochimaru, she immediately rose to her feet.

"Tsunade, it's me," Shamu spoke up at once.

Tsunade hesitated. Dan Katō had just told her that Shamu had learned the Spirit Transformation Technique.

"You're Shamu?"

Shamu nodded.

"I'm going to use Urashiki's Rinnegan to revive Kushina and see whether it works."

"If it succeeds, we'll be able to revive people reliably from now on."

Tsunade was startled at first, then her expression turned solemn. "What do you need me to do?"

"The Rebirth Rinnegan Technique requires an enormous amount of Chakra and life energy."

"Although this body belongs to the Otsutsuki Clan, I'm not sure whether it will die."

"If this body's energy runs out, you must use your medical ninjutsu to keep it alive."

"I'll return to my own body and use the Reanimation Jutsu to replenish this body's lost life energy."

Tsunade nodded seriously. "I understand."

Controlling Urashiki, Shamu walked over to his own body and took out a Storage Scroll.

"Replace one of my body's eyes with a Sharingan first."

Tsunade untied the Storage Scroll as instructed. Inside was the Three-Tomoe Sharingan Shamu carried with him.

For Tsunade, replacing an eye was merely a minor operation.

She finished replacing Shamu's eye in no time.

Meanwhile, Orochimaru had already taken out part of Kushina's corpse.

Then he dragged over a White Zetsu.

Orochimaru performed the Impure World Reincarnation Jutsu with practiced ease.

Tsunade had seen it several times before as well.

Impure World Reincarnation Jutsu!

Orochimaru slammed a palm against the ground.

The ground flared brightly. Amid the wailing yin wind, paper talismans covered the White Zetsu's body.

After the paper talismans dispersed,

Kushina appeared before them, her red hair flowing as she wore a sleeveless shirt and a green skirt outfit.

Kushina blinked.

"Huh? Lord Orochimaru, is it time again? Where are Minato and Naruto?"

Orochimaru answered in a hoarse voice, "We didn't tell Minato. Naruto is next door."

This was not Kushina's first revival.

After Minato had been revived,

Orochimaru had used the Impure World Reincarnation Jutsu to revive Kushina twice.

It had mainly been so she could see Naruto.

Aside from requiring a living sacrificial offering, the Impure World Reincarnation Jutsu also damaged the soul.

So over such a long period, Kushina had only been revived twice.

Each time lasted no more than two days. They had previously agreed to revive her once a year.

It had only been around half a year since Kushina's last revival.

Kushina had no sense of time in the Pure Land and did not know exactly how much time had passed.

But she felt that the interval this time had been rather short.

Wearing Urashiki's face, Shamu asked Kushina,

"Kushina, guess who I am."

To his surprise, Kushina immediately saw through Shamu's identity.

"You're Shamu. Why do you look like this?"

Shamu was a little surprised. "You recognized me right away?"

Kushina smiled. "Your Chakra hasn't changed."

Shamu had not known Kushina was so perceptive.

"This time, we're trying to see whether we can revive you. So neither Minato nor Naruto knows."

Kushina was both startled and delighted.

"Really, Shamu? So suddenly?"

Shamu's expression remained grave. "This attempt may still fail, so you need to be mentally prepared."

Kushina smiled. "Even the chance to attempt a revival is precious. I'm already very satisfied."

Shamu nodded. "All right. We'll discuss the rest afterward."

He had already asked Dan Katō in advance. If a soul could not sustain the Spirit Transformation Technique, it would automatically return to its own body.

Shamu had activated the Spirit Transformation Technique through the system's power. With the system compensating for it, he had no idea how much the technique consumed.

He gave Tsunade a look, and she signaled that she was ready.

This time, Shamu clasped his hands together and began drawing upon this body's energy and ocular power.

The Otsutsuki body's energy was of a higher level than Chakra, but it was slightly harder to manipulate.

If Chakra was like flowing water, the energy within an Otsutsuki was more like rubber.

Shamu moved it very slowly.

Fortunately, Shamu was extraordinarily gifted. With his talents in ninjutsu analysis, Chakra control, and the like,

the energy and ocular power gradually began to move together.

By then, three minutes had already passed.

Everyone around them waited patiently. After all, this was a different Rinnegan, and whether it could be used depended on the situation.

Rebirth Rinnegan Technique!

Shamu gave a low shout.

Urashiki's Rinnegan erupted with ocular power.

Smoke began to rise from Kushina's body as it gradually transformed into the body of a living person.

However, the ocular power of Urashiki's Rinnegan was also rapidly declining.

Its life energy began to decrease.

Shamu steadied himself and continued pouring out ocular power.

Since it was not Madara's pair of eyes, the Rebirth Rinnegan Technique's energy conversion rate was much lower.

The consumption of ocular power was also enormous.

The drain on life energy was even more staggering.

Revival required an exchange of energy, and Kushina's own Vitality exceeded Shamu's expectations.

The first time he used Rinne Rebirth through the Rinnegan, he had encountered an Uzumaki Clan member with the greatest Vitality he had ever needed to revive.

Shamu felt as though the Rebirth Rinnegan Technique was a vampire, constantly draining Urashiki's life energy and ocular power.

Finally, once Kushina was revived, Urashiki's eyes had dimmed considerably.

Kushina's body had finally completed its revival.

As Shamu let out a breath, he also felt his body growing light.

His Vitality had been depleted too heavily.

"Tsunade..."

Shamu called out. Tsunade placed her hand against Urashiki Otsutsuki's back, healing light glowing in her palm.

At the side, Orochimaru administered the prepared emergency medicine to Urashiki.

Shamu's soul left Urashiki's body.

Then it flew toward his own body.
