Cooperation ninjutsu is actually a very common method of using ninjutsu.
For example, Naruto's favorite Harem Technique.
In essence, it is a combination of Multiple Shadow Clone Technique and Sexy Technique.
There is also the Typhoon Water Vortex Technique, which is a combination of Naruto's Wind Release: Rasengan and Yamato's Water Release: Tearing Torrent.
These are all ways to use combined ninjutsu.
It's just that there's no need to get entangled in combat-oriented combined ninjutsu.
Some auxiliary combined ninjutsu are also good.
For example, the Flying Thunder God Mutually Instantaneous Revolving Technique is when two people each perform the Flying Thunder God Technique at the same time.
Continuing to expand his thinking, Kiyoshi can modify his current training method.
The existing method of strengthening his body with lightning release must be carried out within a safe range, because it is essentially a tearing and stimulation of cells.
Exceeding the limit too much will not only damage the chakra pathway system, but also the physical body.
What if medical ninjutsu is used to repair while tearing the muscles?
Then his lightning release's effect on strengthening the body will probably increase and accelerate by several times.
Cooperation ninjutsu does not stipulate that it must be compatible to be combined.
Even things that are completely unrelated or even mutually restrictive can be combined.
"Come here."
After pondering for a moment, Kiyoshi closed the trait panel and beckoned the white snake over.
The white snake raised its small head, its tongue catching the changes in the scent of the air, and slowly crawled onto Kiyoshi's hand.
Kiyoshi stared at the white snake and suddenly thought of the Inuzuka clan's Human-Beast Combination Transformation, which is also a type of cooperation ninjutsu.
The white snake also possesses a healing effect.
Can they merge during battle?
Moreover, this type of technique wouldn't require Kiyoshi to overly focus on controlling his chakra.
'A single blue trait can impact my current fighting style. I need to acquire more blue traits as soon as possible.' Kiyoshi thought to himself.
According to the usual routine, purple should come after blue.
Kiyoshi wasn't sure if the higher-rank trait would be purple.
At this moment
Knock! Knock!
"Kiyoshi, are you home?"
A soft knock sounded, along with a familiar voice.
"Coming."
Kiyoshi put down the white snake and went to open the door.
It was Natsu.
He had just obtained a blue trait, and now he had a chance to increase his pupil power. Life was becoming more and more promising.
The door slid open, and Kiyoshi saw Natsu standing outside.
She was holding a basket in her hand, her black maid outfit gently swaying in the breeze.
The moment Natsu saw Kiyoshi, her shoulders visibly relaxed, as if a weight had finally been lifted from her heart.
"That expression is quite different from last time."
Kiyoshi leaned against the door frame, the corner of his mouth slightly raised.
He playfully teased, "Happy to see me?"
Natsu pursed her lips and said, "Ginka-sama asked me to come."
Natsu didn't pay attention to Kiyoshi 's teasing words. She just wanted to fulfill Ginka's request and set a time for Kiyoshi to meet with Ginka.
Kiyoshi stepped aside, letting her in. Natsu walked into the courtyard carrying the basket.
Kiyoshi turned around, closed the door, and quickly followed.
This was Natsu's first time at Kiyoshi's house. Her first impression was that it was a bit dilapidated.
But soon, her attention was drawn to a white snake that was coiled on the table.
The snake was small and exquisite, with smooth scales. It curled up slightly on the table, lazily flicking its tongue.
Kiyoshi sat in front of the low table, and the white snake slowly wrapped around Kiyoshi's hand.
There was only one stool, so Natsu had to kneel in front of Kiyoshi.
She lowered her head and took out the pastries she had bought outside, saying.
"This is Ginka-sama's apology gift, and she also asked me to help her arrange a time to meet with you."
Kiyoshi lowered his head and stroked the snake's head, saying, "Why didn't she come herself?"
"She's probably afraid of not seeing you when visiting."
Natsu placed the gift box containing the pastries on the low table.
The timing could indeed be off, she had missed Kiyoshi several times.
Natsu didn't dare to imagine what Ginka's expression would be if she tried to find Kiyoshi several times and found he wasn't home.
"Tsk, is she really this insincere?"
Kiyoshi chuckled and looked up at her, his eyes putting a strange pressure on Natsu.
"If she doesn't want to come, then don't."
"Kiyoshi, it's not like that, it's..."
Seeing Natsu trying to explain, Kiyoshi interjected, "My time is limited, I have no time to deal with the prejudiced Hyuga clan. Talk to the Uchiha clan leader if you have anything to say."
Natsu looked bitter, worried in her heart.
She knew very well that if she couldn't bring back definite news this time, what awaited her wouldn't be just a scolding.
Natsu had personally seen the Caged Bird Curse Seal on the members of the branch house being activated.
The pain was so great that it made them wish they were dead.
The thought of such punishment possibly falling on her made Natsu feel a chill down her spine.
Natsu asked, "Kiyoshi, what exactly will it take for you to agree?"
Kiyoshi said, "Shouldn't you ask your main family lady that question?"
Kiyoshi looked at Natsu, whose eyes seemed to be filled with tears, and couldn't help but chuckle.
The Hyuga clan is a clan that has taken feudal rule to the extreme.
In addition to the clan leader's lineage, there are many other branches.
However, among the children born to the main family, only the eldest son can continue to be part of the main family.
The second son who can't be a part of the main family will be marked with the Caged Bird Curse Seal.
For example, Hizashi and Hiashi, these twin brothers.
Just because Hizashi was born a little later, he became the younger brother.
Thus, he could only have the curse mark engraved on his forehead and become a member of the branch house.
Other branch house members, whether they are the eldest or not, have the same fate.
But the Hyuga clan, which seems so strict and hierarchical, also likes double standards.
Hinata and Hanabi, which one of them was implanted with the curse seal?
Natsu lowered her head, biting her lip, waiting for Kiyoshi's response.
Kiyoshi didn't rush to answer, he just looked at her indifferently, with that faint smile still on his lips.
"Are you very afraid of Ginka punishing you?" He suddenly asked.
"...No."
Natsu quickly denied.
The Hyuga clan had strict rules, and if the main family knew she was gossiping, they would definitely say she was disobedient and had complains about the Hyuga clan.
"Do you know? Snakes shed their skin every once in a while, shedding their old skin and becoming stronger." Kiyoshi said.
Natsu frowned slightly, not understanding what he meant by suddenly bringing this up.
Kiyoshi raised his head and looked directly at her.
He asked, "Can the branch house really never change their destiny?"
Actually, there were ways to remove curse seals in this world, such as violent cracking, letting the curse mark destroy the brain and eyes before resurrecting.
Natsu's breathing paused.
This was a topic that couldn't even be discussed.
Seeing Natsu's face change slightly and her head lowered, Kiyoshi stopped talking.
He put down the snake, picked up the tea with his other hand, took a sip, and continued, "Forget it. Regarding the matter of Ginka, you can pay a small price to regain my forgiveness."
Kiyoshi stroked the white snake's smooth scales.
"What...what price?"
Natsu looked at Kiyoshi's dark eyes, her unease growing more and more serious.
Last time, Kiyoshi had made her reveal the Caged Bird Curse Seal.
What would Kiyoshi do this time?
"Don't be nervous."
Kiyoshi began to check Natsu's attire.
