Mangekyō Wood Release Experiment

"What incredible power! This is the strongest Uchiha!"

Zensui regained his adult form, revealing a fanatical expression, and loudly praised Naraku's Dōjutsu.

Zensui clenched his fists, his body surging with powerful Chakra, and his eyes Flash Cut red as he activated his Sharingan.

With abundant Chakra and powerful eye abilities, he is a rare and powerful ninja in the Uchiha.

"Zensui, I will grant your wish and lead the Uchiha to dominate the Shinobi World and become the royal family of the empire."

My strength comes not only from the power of the Uchiha, but also from the power of the Senju. Uchiha and Senju combine their powers, they can create All Things in Nature.

"The power of Senju is somewhat dangerous. Do you wish to wield the Power of All Creation like I do?"

Seeing Zensui's Zensui at regaining her strength, Naraku had an idea.

"The power of Senju? The All Things in Nature? Naraku, you can withstand it, and I certainly can too! Bring it on!"

Zensui completely ignored the dangerous words in Naraku's speech.

If the clan leader can succeed, then his Zensui will naturally not be a problem either.

"Hahaha, clever!"

Naraku laughed heartily in praise, and a swirling wind appeared in his palm, revealing a thin glass tube containing a green liquid.

"There are still many secrets in this world, but the power of the Senju must be the fastest way to make the Uchiha stronger!"

The Senju Clan, which had originally retired, perished completely due to experiments on the First Hokage's Senju power, and many others were sacrificed in subsequent experiments.

However, reliable data was eventually obtained, and powerful ninjas with the strength of Senju were successively created.

I built upon the work of those who came before me, and subsequent experiments yielded a fairly good success rate, but the risks remained considerable.

Now, do you still want this power?

Naraku shook the glass container in his hand, his words carrying a threatening tone.

Zensui smiled slightly and said:

"Chief, please don't say any more. You've told me this because you want my consent, right?"

I'm really looking forward to this power, come on!

After Zensui finished speaking, he Naraku, rolling up his sleeves as he went.

"Ha, alright. This dosage has a high success rate; it's the result of countless experiments."

I also want to learn some lessons from you to help Ruofeng and Inabi with their strategies later."

Seeing Naraku revealed some more secrets, grabbed Zensui's outstretched arm, and injected the First Hokage Cells.

After the injection was completed, Naraku licked his lips slightly and whispered:

"The observation period is one week. During this week, you can rest well in the yard. I will keep an eye on things here every day."

"Good!"

After receiving the First Hokage Cells, Uchiha Zensui answered softly. From the outside, it seemed as if there was no reaction after the First Hokage Cells were injected.

"Have a good rest."

Naraku his instructions and turned to leave.

"Um."

Zensui watched Naraku's departing figure.

"Iron, temporary assignment. Your squad will observe this place 24 hours a day for a week. Report to me immediately if there are any issues with the people inside."

After Naraku arrived outside the courtyard, he called out, and a member of the Anbu appeared before him. He then quietly issued the mission.

"Hi!"

Uchiha Tekka gave a soft reply.

Seeing this, Naraku nodded and strode away.

After Uchiha Naraku left, he waved his hand, and three more figures reappeared in the arena.

One week later

Uchiha Clan Compound

Naraku stepped into the courtyard of the Second Elder Uchiha Kyo's residence once again.

"Zensui, I didn't expect you to adapt to the power of the Senju so well. How does it feel?"

Naraku would come to check on him every day for the rest of the week. Each time, Uchiha Zensui would be meditating and resting, or studying books as before, showing no signs of danger or pain.

"This power suits me well. I can feel my Sharingan's power increasing, and my body's Chakra level is also increasing. The Dōjutsu seem to consume less eye power... Is this the All Things in Nature?"

Upon seeing Naraku enter the courtyard, Zensui stood up to answer Naraku's question.

"Indeed, this is the All Things in Nature. With the blessing of this power, the benefits to the Sharingan are beyond words."

I'm so glad you can adapt. The future of the Uchiha might really depend on you.

Naraku observed Zensui's condition and, seeing that Zensui was radiant, nodded slightly.

"I only need to complete my mission and fulfill my duties. As for the future, that's for you to consider, Lord Naraku."

Uchiha Zensui shook his head, showing no arrogance despite gaining power, seemingly having truly calmed down.

"Not arrogant or impatient, very good. Zensui, I still have a power, a power powerful enough to transform mortals into immortals, but it also carries danger..."

"Come on, Lord Naraku, I am one of the top ninjas of the Uchiha. I believe you have your own reasons for your arrangements for me... Come on!"

Zensui interrupted Naraku and immediately agreed.

"Hehe, okay, I'd better demonstrate it for you first."

At the back of Naraku's neck and spine, the Cursed Seal Tomoe magma-like light rapidly covered Naraku's entire body, turning Naraku skin grayish-black.

Under the Cursed Seal, Naraku's aura grew stronger and stronger. His skin turned grayish-black for only two seconds before returning to its original color. However, Naraku exuded a powerful and ethereal aura.

"This is?"

Zensui stared wide-eyed at Naraku. The more he interacted with Naraku, the more he discovered that Naraku had many secrets, one after another.

"Not bad, your Sharingan should be able to detect the difference in my Chakra right now."

Naraku replied with a smile.

"This is... this is Chakra that a human can possess!?"

Zensui was even more dumbfounded, his scarlet eyes fixed on Naraku.

With the aid of the Hero Water, Naraku's Natural Energy refining process has filled his dantian halfway, and it will soon solidify.

In his usual Naraku state, he only uses temporarily refined Chakra, and he doesn't use this power at all when fighting others.

If this concentrated energy from the dantian were truly utilized, even a simple Ninjutsu could be displayed on an earth-shattering scale.

"Knowing this secret is good. In a fight, I won't need to use my full strength at all. Alright, come on, Zensui!"

Naraku deactivated his state, his skin turned grayish-black, then the grayish-black transformed into a bright, yellowish-red magma, and retreated to the Cursed Seal on the back of his neck and spine.

The terrifying Chakra within Naraku's body then disappeared.

Uchiha Zensui swallowed hard, watching as Naraku's palm swirled and produced a thin glass tube filled with blue liquid. He Naraku with a somewhat dazed look in his eyes.

The vessel in Naraku's hand contained a blue liquid. Naraku intended to use the Cursed Seal prepared with Hero Water against Uchiha Zensui.

A talent with the Mangekyō Sharingan, their status is slightly more luxurious.

"This is my own God Cursed Seal. With this power, if we're just comparing Chakra, you're second to none among the Uchiha. But power is important, technique is important too..."

Strength is important, but technique is also important. Compared to Dōjutsu, Obito's current dual Kamui is the most invincible, with intangibility for defense and long-range Kamui for offense.

Naraku injected the Cursed Seal into the back of Zensui's spine, then put away the vessel, placed his left palm on the Cursed Seal, and made a hand Hand Seals with his right hand, injecting a thin thread of soul.

The God Cursed Seal is power, but also a shackle.
