Orochimaru's "Orochimaru-Style Body Replacement Technique" can be said to be one of Orochimaru's signature ninjutsu.
It's a variant of the Substitution Technique. It allows one to shed a layer of skin to escape the opponent's restraints.
In the battle between Sasuke and Itachi, after being hit by Amaterasu, Sasuke used the Orochimaru-Style Body Replacement Technique to shed his skin and successfully evaded Itachi's pupil technique.
Of course, just Orochimaru-Style Body Replacement Technique isn't enough. This technique also has a complementary ninjutsu called Soft Physique Modification.
After learning this technique, one can greatly enhance their flexibility and elasticity. It's a secret ninjutsu created by Orochimaru himself.
The modified body can freely extend, contract, or twist to any angle, and one can even turn their limbs into whips to launch attacks.
Only by learning Soft Physique Modification can one use Orochimaru-Style Body Replacement Technique like a snake at will.
"Here you go."
Kiyoshi and Anko walked to a dango shop, and Kiyoshi handed her a skewer of dango. Anko happily took it before leaving.
Kiyoshi put away the scroll and bought some ingredients before heading home.
…
"A new vessel… I can feel your fear… and confusion. You understand, don't you? You are more bound than I am…"
Kushina frowned tightly in her sleep.
She dreamed that she was in a dark, oppressive place, with cold water wetting her ankles.
Before Kushina stood a gigantic figure with ferocious fangs.
"Let me liberate you…"
The beast, like a fox, opened its blood-drenched maw.
"Ah!"
Kushina woke up from her dream.
Startled, she sat up and took a sip of water from the glass on her bedside table. After finishing the water, Kushina put the glass down.
On the bedside table, there was not only an empty water glass but also Mito's photo.
Kushina rubbed her face, finished washing up, and looked out the window.
"It's the same scenery as always, and the same two watchers as always."
Kushina felt suffocated.
Although, to protect her privacy and prevent her from going completely insane, the two watchers would not monitor her when she was using the toilet, bathing, or changing.
Most of the time, they lurked in the distance, sensing if there were any changes in her chakra.
Two Anbus, who had been on the rooftop of the building opposite all night, saw Kushina leave the house and flashed in front of her.
"What are your plans for today?" The Anbu asked.
This was a necessary procedure, recorded daily and then reported.
"Training sealing techniques with Minato."
Kushina continued with the same reply as always.
Every day was the same, without any novelty.
She had finished reading the picture book Kiyoshi had given her long ago. The bored Kushina had even flipped through it several times.
"Anyway, as long as you don't leave the barrier, we won't interfere with anything else."
"Okay, I know."
Kushina opened the window and looked outside. Today's conversation was the same as always.
After watching for a while, Kushina closed the window, planning to go find Minato.
She had agreed to study sealing techniques with Minato today.
Minato's arsenal of sealing techniques were basically all taught by her personally.
They were secret sealing techniques of the Uzumaki clan, including the Four Symbols Seal and so on.
Kushina didn't know why the higher-ups of Konoha hadn't objected to her teaching sealing techniques to Minato.
But as long as it was good for Minato, that was enough. Kushina didn't want to care about anything else.
…
Kiyoshi's house
The white snake opened its black eyes and slowly climbed onto Kiyoshi's neck, coiling into a circle, like a scarf.
Kiyoshi ignored the white snake's actions. The white snake had low intelligence, probably only that of a three or four-year-old child.
For Kiyoshi, as long as it was loyal and obedient, that was enough. Abilities were secondary.
He stroked the white snake's cold scales and opened the trait panel.
[Pure Genjutsu Scholar (White)]
[Requirement: Learn 1 pure genjutsu technique.]
[Progress: 98%]
[Effect: Your genjutsu foundation is solid, any genjutsu you use will be enhanced by 5% based on the original.]
[Note: Can be upgraded.]
"Almost there."
Kiyoshi estimated that he could master it tonight. He closed his eyes and continued to practice.
As he grew older, his chakra reserves were increasing day by day.
With dual bloodlines and a trait panel, his development speed was unimaginable to others.
Crack!
Electricity surged through Kiyoshi's body again, slowly flowing through, making his body even stronger.
While others were still using inefficient training methods, Kiyoshi could use his high chakra control to quickly strengthen himself.
He was getting stronger every minute and every second.
…
"I'll be very strict today too!"
Finally, Kushina saw Minato at the agreed-upon location.
She waved her small fist excitedly and said, "There are still many, many sealing techniques of the Uzumaki clan that you have not yet learned. Next we will…"
"Sorry, Kushina…"
Minato interrupted Kushina, who was speaking enthusiastically.
Kushina showed a puzzled expression.
"Today I want to practice other ninjutsu in another place… I came to tell you." Minato said with a stiff face.
He could imagine that Kushina would definitely be angry. But THAT technique was in it's final stages of creation.
If he doesn't finish creating it during this time, when he becomes a Jonin instructor, he will have even less time to focus on that ninjutsu. He has to seize the time.
"What technique?"
"That… I"
Minato stammered but he couldn't say it.
Kushina instantly looked disappointed and said, "I see, it's a ninjutsu that I can't be told about either."
Minato said, "No, it's because it's not finished yet. It's very dangerous, I don't want you to get hurt…"
"If you hate being with me, just say it!"
Kushina was so angry that her bright red hair was about to rise.
Unfortunately, before Minato could explain to Kushina, someone called out his name and walked over.
Seeing this, Minato had no choice but to say goodbye to Kushina first and walk towards the distance.
"Ah…"
Kushina looked disappointed.
Minato actually stood her up.
"Kushina, did something happen?" Kiyoshi asked as he passed by.
Besides practicing at home, he planned to come out in his spare time to try his luck and see if he could meet Kushina and Minato.
Kiyoshi was lucky, he met them on his first try.
"Minato stood me up." Kushina sighed.
The carefree her wouldn't hide her worries from others. Especially since Kiyoshi had the same situation as her.
This made Kushina feel like she had seen a kindred spirit.
