The Great Snake Escape Jutsu given by Orochimaru was one of his signature Ninjutsu.
It was a variation of the Substitution Jutsu
It allowed the user to shed an outer layer of skin to escape from an opponent's restraints.
In the battle between Sasuke and Itachi, after being hit by the Amaterasu, Sasuke used the Great Snake Escape Technique to shed his outer skin and successfully evade Itachi's Dōjutsu.
Of course, the Great Snake Escape Technique alone was not enough. The technique had a complementary Ninjutsu called Soft Physique Modification.
After learning this technique, the user's flexibility and extensibility are greatly enhanced. It was a secret technique self-created by Orochimaru.
A body modified by this technique could freely extend or twist at any angle, and the hands and feet could even be used as whips to attack.
Only by learning Soft Physique Modification could one use the Great Snake Escape Technique with the same ease as a snake, essentially vomiting themselves out of the old body.
Otherwise, the user could only shed the outer layer, exposing the layer beneath.
"Here you go." The two arrived at a dango shop, and Kiyoshi handed her a three-color dango.
Anko Mitarashi gleefully accepted it and finally departed.
Kiyoshi put the scroll away, bought some ingredients, and headed home.

"A new vessel… I can sense your fear… and confusion. You understand, don't you? You are the one who feels more constrained than I do…" Kushina tightly furrowed her brows in her sleep.
She dreamed that she was in a dark, claustrophobic place, with icy water soaking her ankles.
A gigantic figure with menacing fangs stood before Kushina.
"Let me be the one to liberate you…" The fox-like beast opened its massive, bloody maw.
"Ah!" Kushina woke up with a gasp.
Startled, she sat up and took a sip of water from the glass on her bedside table.
After drinking a whole cup, Kushina put the glass down.
There was not only an empty water glass on the bedside table but also a photo album belonging to Mito Uzumaki.
Kushina rubbed her face. After washing up, she looked out the window.
"It's the same old scenery, and the same two monitors as always." Kushina felt suffocated.
Although, to protect her privacy and prevent her from going completely mad, the two monitors would not observe her when she used the toilet, showered, or changed clothes.
Most of the time, they were hidden far away, sensing for any changes in her chakra.
The two Anbu monitors, who had been guarding on the opposite rooftop all night, saw Kushina leave her house and instantly flickered into her presence.
"What is your schedule for today?" the Anbu asked.
This was a necessary daily procedure for recording and reporting.
"Training sealing techniques with Minato." Kushina gave the same answer as usual.
Every day was the same, lacking any novelty.
She had finished the picture book Kiyoshi gave her a long time ago, and bored, Kushina had reread it several times.
"You absolutely must not leave the barrier. We won't interfere with anything else, Kushina Uzumaki."
"Alright, I know." Kushina opened the window and looked out.
Today's conversation was the same as always.
After watching for a while, Kushina closed the window, intending to go find Minato.
She had arranged to practice sealing techniques with Minato today.
Minato Namikaze's sealing techniques were mostly taught by her personally—all secret techniques of the Uzumaki clan, including the Four Symbols Seal, among others.
Although Kushina didn't know why the Hidden Leaf elders didn't object to her teaching sealing techniques to Minato Namikaze, as long as it was good for Minato, that was all that mattered.
Kushina didn't care about the rest, and even if she knew the reason, no one would explain it to her.

Kiyoshi's house.
The white snake opened its black eyes and slowly crawled onto Kiyoshi's neck, coiling around it like a scarf.
Kiyoshi ignored the white snake's actions.
The white snake had very low intelligence, roughly equivalent to a three- or four-year-old child.
For Kiyoshi, as long as it was loyal and obedient, that was enough.
Ability was secondary.
He rubbed the white snake's cool scales and opened the Trait panel.
[Trait: Pure Genjutsu Scholar (White)]
[Requirement Achieved: Learn 1 pure Genjutsu technique.]
[Progress: 98%.]
[Effect: Your Genjutsu foundation is solid. All Genjutsu used are enhanced by 5% on top of the original base.]
[Note: Can be further advanced.]
"Almost there." Kiyoshi estimated he would master it by evening.
He closed his eyes and continued his training.
As he grew older, his chakra reserves increased daily.
With his double Bloodlines and the Trait panel, his development speed was unimaginably fast compared to others.
*Crackling!*
Electricity once again surged through Kiyoshi's body, slowly flowing through him.
It tempered his body, making it stronger.
While others were still using inefficient training methods, Kiyoshi could rapidly strengthen himself due to the benefits of high chakra control ability.
He was growing stronger every single moment!

"I'll be very strict today!" Finally, Kushina saw Minato at their meeting spot.
She enthusiastically raised her small fist and said:
"And Minato understands things so quickly. Because the Uzumaki clan has many, many more sealing techniques, next we need to…"
"I'm sorry, Kushina…" Minato Namikaze interrupted Kushina, who was getting carried away.
Kushina looked puzzled.
"I want to practice a different Ninjutsu in a different place today… I came here to tell you." Minato Namikaze said, steeling himself.
He could imagine Kushina would be angry.
But that technique was close to being developed.
If he didn't develop it during this period, he would become a Jonin squad leader, and then he would have even less time to develop Ninjutsu.
He had to hurry.
"What technique?"
"That… I…" Minato Namikaze stammered, unable to speak.
Kushina instantly looked disappointed, saying, "I get it. It's a Ninjutsu you can't tell me about."
"No, it's because it's not finished yet, and it's very dangerous. I don't want you to get hurt…"
"Just say it if you hate spending time with me!" Kushina was so angry that her bright red hair seemed to flare up.
Unfortunately, before Minato Namikaze could explain to Kushina, someone called his name to come over.
Seeing this, Minato had no choice but to say goodbye to Kushina and walk away.
"Ugh…" Kushina looked utterly disappointed.
Minato actually left.
"Kushina, did something happen?" Kiyoshi, who was passing by, asked.
Apart from training at home, he would come out in his free time to try his luck, hoping to run into Kushina and Minato.
Kiyoshi was lucky; he succeeded on his first try.
"Minato left me standi." Kushina sighed.
Being carefree and open, she wouldn't hide her thoughts from others.
Especially since Kiyoshi had a similar background to her, this made Kushina feel a kinship, as if seeing a fellow traveler.
