Because Ryou has Sasori's memories, he knows the triggers for all of the Third Kazekage's Magnet Release Secret Techniques.
Under Ryou's control, the Third Kazekage released iron sand from its mouth.
The Third Kazekage's iron sand wasn't created out of thin air, but was sealed inside its body by Sasori.
Once used, it's gone.
"Magnet Release: Iron Sand Drizzle!"
The wave-like iron sand formed countless fine needles that shot downward, covering an area of dozens of meters like a cloud of black rain.
Ryou laughed loudly, "Good stuff! Sasori, you really are a damn genius!"
"Hmph!"
Sasori snorted, not accepting Ryou's praise.
The Third Kazekage was a good tool, but Ryou was already strong enough with Wood Release and the Sharingan.
He patted Candy's head, "Candy, I'll pass Sasori's Puppet Technique to you. From now on, you'll control the Third Kazekage."
"Okay!"
Candy nodded.
After passing the Puppet Technique to Candy, Ryou retracted the Wood Dragon and descended with several Ninja Cats.
Since they had reached an inhabited area of the Land of Wind, they couldn't continue flying so conspicuously.
Relying on Sasori's memories of Sunagakure, Ryou found a shortcut and headed toward the Village.
On the way, Sasori had already guessed Ryou's objective.
"You're going to Sunagakure to capture Shukaku, aren't you?"
It wasn't hard to guess. Since Madara's Eye of the Moon Plan was exposed by Konoha, the entire Ninja World now knew that Madara intended to capture the Nine Tailed Beasts.
The Tailed Beasts were concentrated in the Five Great Ninja Villages, and the one Sunagakure possessed was the One-Tail, Shukaku.
Ryou was heading toward Sunagakure, and he certainly wasn't going there to visit relatives. It could only be for the One-Tail, Shukaku.
Ryou nodded and stated his goal, "That's right. I've come for the One-Tail, Shukaku."
There was no need to hide it.
Sasori was a rogue ninja from Sunagakure. In the original work, he was the one who had Yura lead the way for Deidara to destroy Sunagakure.
As for the Fourth Kazekage Rasa being killed by Orochimaru, Sasori had a hand in that too. Not personally, but by having his spies in Sunagakure support Orochimaru.
Sasori was involved in the deaths of three generations of Kazekage: the Third, the Fourth, and the Fifth, Gaara.
Sasori had completely fallen and felt no affection for his former Village.
But Ryou's true goal wasn't just the One-Tail, Shukaku.
There was also Chiyo's Forbidden Jutsu, the One's Own Life Reincarnation Jutsu.
This Forbidden Jutsu uses all of one's Chakra as a medium to transfer one's own life force entirely to another.
In the original work, Chiyo used this technique to revive the deceased Gaara.
Chiyo developed it after seeing Sasori's loneliness and wanting to resurrect his parents.
Sasori had never seen Chiyo's sincere love for him.
Why did Ryou want Chiyo's One's Own Life Reincarnation Jutsu so badly? Weren't his Creation Rebirth and Plunder Rebirth enough?
Not enough!
Ryou's life Secret Techniques couldn't bring people back from the dead; they could only restore a dying person to their best state or return an elderly person to their peak.
If someone died, Ryou had no way to resurrect them.
He had already guessed that Madara would target Tsunade to force him to awaken the Mangekyo Sharingan.
Ryou needed a countermeasure.
As long as Tsunade's body remained, Ryou could use One's Own Life Reincarnation Jutsu to revive her.
And Chiyo's One's Own Life Reincarnation Jutsu was Ryou's target.
But there was a problem: he couldn't be sure if Chiyo had already developed One's Own Life Reincarnation Jutsu.
After all, in the original work, Chiyo only revealed it for the first time during shippuden.
It was currently the Year 51 of Konoha, more than a decade away from shippuden.
Furthermore, during the period from the death of Sasori's parents to the end of the Third Great Ninja War, wars were frequent, and as a high-ranking member of Sunagakure, Chiyo didn't have much free time.
Regardless, Chiyo's One's Own Life Reincarnation Jutsu had to be secured.
Even without One's Own Life Reincarnation Jutsu, Ryou would seize Madara's Rinnegan to resurrect Tsunade.
This was the advantage of knowing the plot; without this information, Ryou would likely have been controlled by Madara just like Obito.
As the sun was about to set, Ryou finally saw The Pass of Sunagakure.
The Land of Wind was a vast desert with constant sandstorms, making it impossible to establish Villages randomly in the wild.
Sunagakure was built behind a reddish-yellow cliff, situated in a low-lying area to block out the sandstorms.
There was only one path in and out of Sunagakure: The Pass.
This was a canyon formed at the junction of the sandstone mountains and the desert. The passage in the middle was so narrow that only a few people could walk side-by-side, and looking up, one could only see a thin sliver of sky.
That's why it was called the Sunagakure Pass.
Candy, Snowy, and Nekomata all dove underground, while Ryou, wrapped in a white robe, slowly approached the Sunagakure Pass through the yellow sand.
The desert at dusk was full of poetic beauty.
The scorching heat of the day gradually receded, and the wild winds lost their ferocity.
The setting sun dyed the sky a deep golden red, its afterglow spilling over the rolling dunes and tracing soft, lonely curves.
A figure emerged from the yellow sand.
The Ninjas guarding The Pass suddenly became alert.
Because The Pass was the only entrance to Sunagakure, it was heavily guarded.
Furthermore, due to the storm Madara had recently stirred up in the Ninja World, Sunagakure was currently on high alert.
There were at least twenty Jonin patrolling The Pass.
Yura, who was still just an ordinary Jonin and not yet a high-ranking official, shouted at the newcomer, "Halt!"
A gentle evening breeze swept through with fine sand, blowing back the hood of the newcomer's desert robe and revealing tufts of red hair.
Behind the hood was the face of a handsome young man as delicate as a doll.
He had neat, ear-length hair, narrow and sharp eyes, pupils as light as glass, and clean, sharp facial features.
He possessed a cold elegance and refinement that transcended his age.
Anyone who saw him would call him a handsome beauty!
But the Ninjas of Sunagakure all widened their eyes in shock.
Yura was so stunned that he couldn't even grip his Kunai, letting it fall.
"Lord Sasori..."
The three-year term is up; the Dragon King Sasori returns!
...
Sunagakure, Kazekage Office.
Rasa was pleading with Chiyo, "Elder, we can find another Jinchuriki. Please, don't make my child one."
Jinchuriki had always been seen as ominous and were treated differently by those around them.
Ninjas needed Jinchuriki to control the power of the Tailed Beasts, yet they ostracized them; it was the height of hypocrisy.
Chiyo shook her head, "No. We've already experimented with three Jinchuriki, and all of them failed."
"Furthermore, the Jinchuriki of every generation have been those close to the Village leader."
"The Eight-Tails Jinchuriki of Kumogakure is Killer Bee, the sworn brother of the Fourth Raikage. I also recently heard that a Mizukage candidate from Kirigakure sealed the Three-Tails within himself."
"Rasa, as the Fourth Kazekage of this Village, can you not make a sacrifice for its sake?"
"..."
Rasa fell silent.
The choice for a Jinchuriki is either the Kage themselves or their direct blood relatives, spouses, or closest kin.
This is to ensure the Jinchuriki's absolute loyalty. Additionally, because the Kage lives with the Jinchuriki, they can prevent a rampage at any time.
That's why Konoha's Fourth Hokage was decided from the start—it was Minato, because his wife Kushina was the Nine-Tails Jinchuriki.
This condition was even more of a plus than 'My Hokage Father'.
The election for the Fourth Hokage was just a formality; whether it was Orochimaru or Fugaku, they were just clowns.
Another reason was talent.
Aside from the Uzumaki Clan, who were best suited for sealing Tailed Beasts, most other suitable candidates were concentrated among the Kages and their relatives.
The children of Kages sweat redder than the blood of ordinary people; they are born with a higher starting point than regular Ninjas.
They are precisely the best candidates for Jinchuriki.
