 ——————————————————————————————————

Passing through the lush forests of the Land of Fire, the scenery suddenly opened up.

An endless green plain stretched before him, with a clear, bright sky adorned by a few fluffy white clouds.

Carrying a backpack as tall as himself, Rinjin stepped into this vast expanse.

"The Land of Hot Water, huh! Back again!"

The mention of the Land of Hot Water brought back memories of the atrocities committed here by Amegakure.

Now, Amegakure had no ties to him anymore. All that remained was an endless, unyielding hatred.

A week had passed since Rinjin set out.

A few days ago, Tsuchinu, who had been assigned to liaise with Rinjin, informed him that Mizuguma's body had been secretly transported from Amegakure to Konohagakure and buried in the villagers' cemetery west of the Hidden Leaf Village.

Although it wasn't placed in the ninja cemetery, this treatment was already quite exceptional for a ninja from another village.

And now that the body was secured, things like *Edo Tensei* or *Rinne Tensei* could all be arranged. With the black technology in the Naruto world, anything was possible!

"Next up, it's my turn~"

Rinjin was no stranger to infiltration. After all, he had successfully infiltrated the Hidden Leaf Village before.

But this time, Hiruzen Sarutobi's request was vastly different from that of Hanzō of the Salamander.

Knowing Rinjin's abilities, Hiruzen had given him a much more challenging task.

Not only did he have to infiltrate Kumogakure successfully, but within three years, he was to integrate into Kumogakure's upper ranks and gather intelligence.

To be honest, it was a bit of a tall order.

But Rinjin didn't mind at all. After all, he was like a kite—once let loose, there was no pulling him back.

Once he reached Kumogakure, what he did there would be entirely up to him.

Thinking about it, Rinjin grinned.

Hmm! The mission could wait. Earning some money and enhancing his strength were far more important!

As for the mission, he could just do it on the side~

With money, he could mess with Hanzō of the Salamander; with increased strength, he could kick him to death later.

So, the ultimate question was how to enhance his strength.

Thinking about his destination, Kumogakure, he got excited.

Among Kumogakure's secret techniques, Rinjin wasn't most interested in the *Lightning Release Chakra Mode*, the *Lightning Release Armor*, any *Kekkei Genkai* like *Storm Release*, or even ninja-taijutsu. What he fancied the most was a space-time ninjutsu designed for logistics—*Heavenly Transfer Technique*.

In his memory, during the Fourth Shinobi World War, that beautiful dark-skinned kunoichi from Kumogakure had used this technique to teleport both the Fourth Raikage and Tsunade to the front lines.

To Rinjin, such an application was a complete waste of the technique.

The *Heavenly Transfer Technique*, in his view, combined logistics, tactics, ambushes, and pinpoint strikes into one—essentially a railgun!

And not just any railgun, but a long-range, precision-guided railgun. Paired with the *Flying Raijin Jutsu*, it was like a Mundo with infinite ammo.

Even if the enemy was right in front of him, he could use control ninjutsu like the *Shadow Imitation Technique* to banish them to the ends of the earth.

At that moment, with a stylish flick of his hair, he could sing, "I send you away, a thousand miles away, with a pile of sh*t flying your way~" Wouldn't that be delightful?

Shaking his head in amusement, Rinjin sighed at the missed potential.

Of course, Rinjin had another, more important goal for this trip: the Two-Tails Jinchūriki... no, no, no... Matatabi!

He had tried countless times to increase his chakra reserves, but the results were always disappointing.

His immortality severely limited his chakra capacity, and with only a mid-level chunin's worth of chakra, his creativity was restrained!

Normally, Rinjin's ultimate goal should be piloting a Gundam, the kind that could grab the Nine-Tails with one hand;

Or becoming a sword saint, waving a fan to unleash a rain of arrows;

Though his style might differ from others, he could use *Magnet Release*. Not utilizing it this way felt like betraying his childhood dreams.

But with such limited chakra, all he could manage was wielding a door-sized sword and throwing out a few *Flame Splitting Wave Rulers*. It was pitiful.

Muttering to himself, Rinjin walked along a rural path, his mind churning with schemes.

Carefully avoiding the center of the Land of Hot Water where the Hidden Hot Springs Village was located, he headed northwest and arrived in the Land of Iron.

The Land of Iron, a neutral country in the ninja world, was home to people who wielded a unique power called samurai techniques.

At the same time, the Land of Iron was the largest producer of iron ore in the ninja world.

Rinjin chose this place precisely because of its iron resources.

He needed money to prepare thoroughly, rather than recklessly charging into the Land of Lightning.

Doing so would only alert Kumogakure, causing his plan to fail and his goal of enhancing his strength to be completely ruined.

Preparation was essential.

...

Another week passed. On the eastern coast of the Land of Iron, far from any villages, a small wooden cabin had been built.

The cabin faced the sea, and beyond the sea lay the towering mountains of the Land of Lightning.

Early in the morning, Rinjin, wearing a straw hat and floral shorts, carrying a bamboo basket, walked out of the cabin and onto the nearby beach.

Taking off his straw hat and setting down the basket, he jumped into the sea with a splash. After swimming freely for a while, he returned to the shore to sunbathe.

Rinjin was marinating himself!

If he was going to be an undercover agent, he needed to look the part.

Rinjin chose the most basic approach: blending in by matching skin color.

Although transformation jutsu was a quick and convenient option, it was only suitable for short-term infiltration as an inconspicuous villager.

But Hiruzen Sarutobi's requirement was to integrate into the upper ranks!

Using transformation jutsu would inevitably lead to problems.

As for whether he could tan, Rinjin wasn't concerned.

Back when he was with the Jashin Cult, he had undergone the "air-drying" process!

It was just that, at the time, he found it inconvenient not being able to see his hands at night, so he had peeled off the blackened skin bit by bit.

After sunbathing for a while, Rinjin took out a palm-sized scroll from the bamboo basket and began reading it intently.

The scroll contained extensive information on Kumogakure's chunin and genin, collected by Konoha's Anbu.

Infiltrating the upper ranks within three years as an outsider was nearly impossible.

So, replacing someone was inevitable.

After reading it over and over, Rinjin found someone he was satisfied with.

The person's name was Raimui, an orphan, fourteen years old, arrogant, reckless, and prone to arguing with teammates over missions.

He was a die-hard fan of the Third Raikage, obsessed with taijutsu, and dismissive of all other ninjutsu and genjutsu.

His social life was terrible. Apart from some interactions with his squadmates, he had almost no connections with neighbors or classmates.

Of course, he had the skills to back up his arrogance. Although he was officially a genin, Konoha's Anbu observed that his taijutsu was already at chunin level.

As for why he hadn't been promoted to chunin, it was because his squad captain believed he lacked the ability to lead a team.

Strangely, despite his personality, he wasn't ostracized much in the village.

Reading this, Rinjin couldn't help but exclaim, "Kumogakure truly deserves its title as the first village of martial arts!"

Someone like this would have been ridiculed endlessly in Konoha with *Byakugan* jokes.

But in Kumogakure, just because of his decent skills, he managed to get by fairly well.

Oh man~ If Sakumo Hatake had been born in Kumogakure, wouldn't he have torn Konoha apart?

Thinking of this, Rinjin chuckled.

Konoha, truly the number one shady village!

But what did that have to do with him? He was from Amegakure! Hehe~

Setting aside the scroll, Rinjin picked up another one with an ancient design and began studying it carefully.

This scroll contained information about heavily guarded locations within the Land of Lightning.

Rinjin had specifically requested this from Hiruzen Sarutobi before setting out, intending to find the location where the Two-Tails was sealed.

After all, currently, Kumogakure had no information about the Two-Tails Jinchūriki, apart from the Eight-Tails Jinchūriki.

And Kumogakure's method of sealing tailed beasts was none other than the Amber Purification Jar. But the Amber Purification Jar had to be reserved for the Eight-Tails, no doubt about it.

If the Amber Purification Jar contained the Two-Tails, what would they do if the Eight-Tails Jinchūriki lost control? Release the Two-Tails and reseal the Eight-Tails?

Clearly, the Raikage wouldn't do that.

So, it was simple. The Two-Tails must have its own separate sealing location.
