Escaping the Mist Ninja starts with backstabbing your teacher.

One week later, Tanba Street.

Izumi, who had left Konoha, brought Momona directly here and booked a room at an inn.

The room was now enclosed by a barrier, sealing off all internal energy and preventing any leakage.

"A nice new barrier. Many of the techniques in this scroll are secret techniques of your Uzumaki clan, which require the physique of the Uzumaki clan to master."

"So study hard and learn everything above."

Upon hearing Izumi's words, Momona looked at the scroll in her hand, her face contorting into a bitter expression, because the contents were all very difficult.

There were many things she only vaguely understood, and figuring them out on her own would likely take a long time. She could only mutter softly, "I'll do my best!"

Then, in a fit of pique, she hugged the scroll, lay down on the tatami mat, crossed her legs, and showed her nimble little feet as she studied it.

Meanwhile, Izumi, standing beside him, paid no attention to any of this, her entire focus being on the pottery jar in front of her, which was covered with sealing spell patterns.

This is the Nine-Tails chakra he collected through his clones, filled with violence and corruption. If it were to enter the body of an ordinary ninja, the consequences would be unimaginable.

Even with the sealing technique, the opponent would likely be unable to withstand this power and would be affected by it, becoming irritable and wild.

Those with the physique of the Uzumaki clan are the best choice to withstand this power, and they are also the well-known candidates for Jinchūriki.

Besides, the next best option is someone with the bloodline of the Sage of Six Paths, who can withstand this power.

Among them, Kinkaku and Ginkaku are the best examples. They were swallowed by the Nine-Tails and survived for two weeks by consuming the Nine-Tails' flesh and blood, eventually obtaining the Nine-Tails' chakra.

The reason they were able to survive and obtain the Nine-Tails' chakra was entirely due to their lineage as descendants of the Sage of Six Paths. They survived by virtue of their strong physique and regenerative abilities.

"Characteristics, will, chakra, and changes in flesh and blood..." Izumikawa murmured to himself, holding the porcelain jar.

Each tailed beast has its own strengths, and Kurama (the Nine-Tails) excels in its powerful regenerative body and its vast chakra reserves.

A wisp of crimson chakra was drawn from his fingertip, instantly making the atmosphere in the room somewhat oppressive.

Momona felt a jolt all over her body, her hair standing on end. Haji Cat, in its Spinosaurus form, shuddered from the back of its neck to its toes.

Momona quickly turned over, leaned against the corner of the wall, shivering, clutching the sealing scroll, and looked at Izumikawa who was studying the Nine-Tails' chakra.

As a member of the Uzumaki clan, she has the most sensitive perception of chakra. She can even sense the tyranny in the Nine-Tails' chakra and its evil intentions towards humans sealing it away.

She could vaguely see that the chakra had transformed into the head of the Nine-Tails, roaring at her.

【optimization】!

As Izumi's supernatural power swept over, the mental roar abruptly ceased, as if it had been choked.

The invisible pressure dissipated, but Momona couldn't stay still any longer. This had been happening every day for some time now, making it impossible for her to concentrate on her studies.

He carefully put away the scroll and called out to Izumikawa, "I'm going to gather information for you!"

"Um!"

Izumi responded with a sound of agreement, but didn't say anything more, while Momona muttered to herself.

Why do you have to look for some "fat sheep" here, or some blonde woman with twin ponytails and super big breasts? I'm not small either!

Momona looked down at her chest, clenched her fists, pouted, and finally opened the door and walked out.

She wanted to see just how big these so-called "large breasts" were that Lord Izumikawa was so interested in them.

……

Momona's departure did not affect Izumi's training. He circulated his internal energy while holding the wisp of scarlet Nine-Tails chakra.

Through continuous optimization of his ability and the cleansing effect of his mental power, the resentment, will, and savagery of the Nine-Tails' chakra were gradually washed away and disappeared.

The stubborn Nine-Tails chakra was completely washed away, leaving only the pure tailed beast characteristics, or rather, the chakra belonging to the Nine-Tails, thus rendering it harmless.

Izumikawa slightly opened his mouth, and as the chakra cluster inside his body pulsated, he inhaled it into his mouth and it entered his body.

The technique circulated within his body, causing the wisp of Nine-Tails chakra to flow, while the [Optimization] was also continuously activated.

While absorbing that wisp of Nine-Tails chakra, the body enhanced its recovery ability and inscribed its characteristics, abilities, chakra ratios, and other aspects into its body.

If he continues in this way and refines the collected Nine-Tails chakra, he will also possess the Nine-Tails chakra, and even the Tailed Beast Cloak mode.

The inscriptions on the body, along with the chakra, continuously merged, progressing towards the physique of a tailed beast and acquiring all the characteristics of the Nine-Tails.

Compared to the brute force fusion of Golden Horn and Silver Horn, his method, although much slower, would have absolutely no side effects.

……

Time continued to pass, the sun set in the west, and the time of twilight had arrived. That wisp of Nine-Tails' chakra was completely refined and absorbed into the body.

The enhanced physical recovery and expanded chakra brought a smile to Izumi's face; this feeling of constantly becoming stronger was truly addictive.

"If I add the Lightning Release Chakra Mode to activate my body, my physique should be able to become faster and more agile."

"With the added power of the Corpse Bone Pulse, ordinary ninjas wouldn't even see me before I've already killed them."

"Unfortunately, I still miss the cells of the First Hokage. That immense vitality seems to be different from the power brought by the Nine-Tails."

After sealing and putting away the jar, Izumi slowly stood up. The throbbing pain in his temples was a sign that he had overused his mental energy.

If you want to recover, besides meditation, the only other option is to get a deep sleep.

I stretched out onto the balcony, looked at the sunset outside, and sat down on a deck chair.

He brewed a pot of tea and took out some sealing techniques copied from the Uzumaki clan's sealing technique scroll, constantly flipping through and studying them.

He couldn't learn the sealing techniques and secret arts that required the physique of the Uzumaki clan, but he had no problem with other aspects.

Unfortunately, he didn't seem to see anything related to the Yin Seal. He didn't know if this technique was developed by Hashirama's wife, Mito, or by Tsunade herself.

"We still need to find Tsunade. The Yin Seal is very useful. It's like a leak-free body, collecting and sealing all the excess chakra produced daily."

"When needed, it will emerge like a floodgate being opened, and it can also regulate cells to achieve eternal youth."

What he wanted was immortality; he desired eternal life, and naturally, he also desired to remain young. Only immortality and eternal youth were his ultimate pursuits.

After reviewing the sealing techniques for a while, Izumikawa looked up at the gradually disappearing sun, his brows furrowing slightly: "Has Momona not returned yet?"
