"Then we'll head out first."
Kiyoshi turned and stepped over the dilapidated doorframe, arriving on the light yellow grassland outside.
Yukari followed Kiyoshi somewhat cautiously.
"Hey, what about these people?"
Ringo pointed to the three Kusagakure ninja who had been immobilized by Kiyoshi's Genjutsu.
"You know what to do."
Kiyoshi didn't say much. He gazed into the distance at the dense forest and rolling mountains.
The Land of Grass is a crucial battle zone in this war, serving as the battleground between the Land of Earth and the Land of Fire.
Although it is a small country, its strength is not to be underestimated. Among the small countries, it is one of the closest to being a major power.
Kusagakure even has its own diplomatic affairs.
They act as intermediaries, establishing a prison on a small island near Kusagakure, specifically for holding offending ninjas.
It can be considered an international prison, holding prisoners from various countries.
The island is surrounded by the sea and located north of the Land of Waterfall. It is named Hozuki Castle because it is covered in a type of groundcherry called Hozuki.
The warden has always been from a clan capable of controlling the Heavenly Prison.
If Fire Release: Heavenly Prison is applied, even Naruto's chakra reserves would be suppressed to the point where he could only use one Shadow Clone.
"Let's settle on a location near the border between the Land of Grass and the Land of Waterfall."
Kiyoshi decided on the location for the experimental base.
He would have to make a trip to Hozuki Castle sooner or later.
Both Naruto the Movie: Blood Prison and the subsequent Boruto series continued this setting.
Hidden within Hozuki Castle is the Land of Grass's greatest ambition: the legendary Box of Ultimate Bliss from the era of the Sage of Six Paths, a thousand years ago, which is said to grant the opener one wish.
Kusagakure once opened it and was said to have almost controlled the world with its power. Later, Kusagakure suddenly declined one day.
Since then, two opposing factions have emerged in Kusagakure: the pro-war faction, which seeks to revive Kusagakure, and the anti-war faction.
The reason why the Land of Grass is so enthusiastic about establishing international prisons for various countries is twofold.
First, to hide the Box of Ultimate Bliss.
Second, to use the chakra of the prisoners to research methods to reopen the Box of Ultimate Bliss.
Of course, this thing will actually absorb the person who opens it, turning them into the monster Satori.
Even so, it is still something very worthy of research. After all, it realizes the transformation of life form, immediately turning a ninja with ordinary combat power into a monster that can beat Sage Mode Naruto.
Furthermore, the Land of Grass also has Ryuzetsu's Clan, which possesses a Kekkei Genkai that allows them to use Reincarnation Ninjutsu, capable of sharing their life force with others.
This is also a very good ability.
In Naruto the Movie: Blood Prison, after Sage Mode Naruto was killed, Ryūzetsu used this move to revive Naruto.
"Hmph, he really knows how to order people around." Ringo grumbled as she came out of the conical house.
Three lives had quietly passed away inside.
Yukari, with her excellent sensory abilities, immediately sensed this change. She silently lowered her head, and said nothing.
These ninja, after returning, would not only bring trouble to her, but also to Kiyoshi.
"Alright, let's go to another place."
Determining the direction by the position of the sun in the sky, Kiyoshi grabbed Yukari with his left hand and Ringo with his right.
Before the two women could react, Kiyoshi shot into the sky. His whole body flashed with lightning as he flew toward the distant horizon.
Listening to the whistling wind in her ears, Yukari was so startled that she burrowed into Kiyoshi's arms.
The distance below was probably several hundred meters.
Yukari didn't dare to open her eyes, only listening to the sound of the wind.
'He... is definitely a very powerful ninja.' Yukari thought to herself.
She had once heard her parents say that neither Uzushiogakure nor Konoha had many ninja capable of flight.
To fly, one must either rely on a unique Kekkei Genkai, or have chakra reserves and chakra control that are extraordinary.
It is probably the most difficult technique besides space-time ninjutsu.
Compared to Yukari secret shock, Ringo appeared much more composed.
She had seen Kiyoshi take out strange things like Mōryō's power, and already knew that Kiyoshi was a ninja who didn't play by the rules.
Ringo asked, "After your chakra is exhausted, we won't fall to our deaths, will we?"
Ringo was not afraid of death, but she didn't want to die so inexplicably.
"Of course not." Kiyoshi smiled slightly.
The white snake in his sleeve skillfully held several military ration pills and sent them into Kiyoshi's mouth.
This made Ringo's lips slightly twitch. Was he really not afraid of military ration pills overloading him and dying from being stuffed?
...
By evening, Kiyoshi had identified a secluded location. He slammed his hands on the ground.
A cave was carved out of the mountain rock.
Rumble...
The cave was deep and constantly expanding inward.
This was the benefit of Earth Release ninjutsu. Building a base was very fast, comparable to Wood Release ninjutsu.
Other ninjutsu such as Wind, Fire, Lightning, and Water were not as convenient as Earth Release.
Ninjutsu changes lives.
Kiyoshi once again realized this. He first expanded a space of fifty square meters to serve as a temporary base.
He had consumed a lot of chakra when using Lightning and Wind Release ninjutsu to travel just now.
He only had a portion of military ration pills left, and he had to save chakra to use the Flying Thunder God Techniquebto return to the Land of Fire.
Traversing two countries would consume an astronomical amount of chakra.
There were advantages and disadvantages to this.
By using the Flying Thunder God Technique at such high intensity, Kiyoshi's understanding of this ninjutsu would continuously improve.
He would optimize the shortcomings as quickly as possible and minimize the chakra consumption.
"These military supplies are for you."
Kiyoshi took out a sealing scroll and handed it to Yukari.
Inside were basic supplies for a week: dry rations, a simple tent, a sleeping bag, a water bottle, an iron pot, and so on.
"...Thank you." Yukari said politely.
The haggardness on her face had lessened slightly, and the short red hair near her chin swayed gently as she nodded.
Her temperament was a little better than Karin's, perhaps because she had seen the world, unlike Karin, who had been treated as a mobile blood bag since childhood.
The only flaw was that her figure was a little too thin. It was probably because she had been hiding for a long time, constantly worried.
