At the Third Training Ground.
"The Flying Thunder God Technique is an S-rank Space-Time Ninjutsu developed by the Second Hokage, so its difficulty is extremely high..."
Minato looked at Seiryū.
He briefly explained the situation regarding the Flying Thunder God Technique. "Of course, if it were only a matter of high difficulty, it could be learned by spending enough time."
"To learn the Flying Thunder God Technique, it is more about meeting certain necessary conditions."
"Having talent in Space-Time Ninjutsu is one aspect, but most importantly, one needs to overcome the discomfort brought about by space-time displacement. This is one of the necessary conditions!"
Overcoming the discomfort brought about by space-time displacement.
This was a necessary condition.
When some people underwent space-time displacement, their bodies would experience discomfort.
Dizziness, vomiting, and lightheadedness were all normal.
Only by overcoming this discomfort could one learn Space-Time Ninjutsu.
Seiryū's mind was very sharp, and he instantly understood what this meant. He said, "Would there be a reaction similar to motion sickness?"
It was not hard to understand.
If one instantly twisted their head from left to right repeatedly, they would also feel dizzy, nauseous, and lightheaded.
The displacement caused by Space-Time Ninjutsu was certainly much more intense than that.
It was very normal to experience discomfort...
"Yes, that's basically the logic."
Minato nodded.
He continued, "Also, I am not too clear about the situation with other Space-Time Ninjutsu, but the Flying Thunder God Technique also requires the user to possess strong reflexes, immediate adaptability, and immediate processing ability..."
"The situation on the battlefield changes in an instant. Only if your reaction speed, adaptability, and processing ability are sufficient can they support you in applying the Flying Thunder God Technique in battle."
Space-Time Ninjutsu was about shifting from one location to another.
Without strong reflexes, adaptability, and processing ability as support, it was impossible to perfectly bring out the effect of the Flying Thunder God Technique...
Seiryū's eyes flashed, and he said, "The faster the speed, the faster the reaction required to instantly judge the situation, make the most correct response, and formulate the next step of action..."
"To avoid the absurd situation of teleporting yourself directly into an enemy's attack, right?"
Speed that exceeded the limit naturally required reflexes that surpassed common sense to support it.
If one's reflexes, adaptability, and processing ability were insufficient, the Flying Thunder God Technique could not be used in battle.
Not only would it fail to help, but it might even harm the user by actively shifting them to the location of an enemy's attack...
"Exactly."
Minato nodded again.
He had never doubted Seiryū's intelligence.
Before he even mentioned the key points, Seiryū had already thought of them himself.
This reaction speed...
He felt that Seiryū did not even need to be tested to see whether he met the conditions in this regard...
Minato smiled and said, "Reaction, adaptability, and processing ability are innate. They can also be considered a type of talent. Although one can train to become stronger, there is a limit no matter how much one trains..."
Such a thing as talent existed.
It was not something ordinary people could surpass just by working hard.
To put it simply, it meant having a higher upper limit in certain aspects.
Even without much training, the innate talent one possessed would be stronger than someone who had gone through long-term training!
"I see."
Hearing that learning the Flying Thunder God Technique required these conditions, Seiryū also sighed. "To overcome the discomfort of space-time displacement, one also needs enough innate reaction speed, adaptability, and processing ability to support it."
"The difficulty of the Flying Thunder God Technique is truly not small..."
It was no wonder that only a few people in the original story had learned the Flying Thunder God Technique.
These conditions were truly harsh.
"These are just two of the necessary conditions..."
"Senpai, don't keep me in suspense!"
Seiryū was somewhat speechless.
You've been talking for a long time, but you still haven't gotten to the main point, right?
"Alright, alright, I was only doing this so you could understand the Flying Thunder God Technique better."
Minato smiled helplessly.
This kid was quite impatient.
So he said, "Let me summarize it simply. To master the Flying Thunder God Technique, the required conditions are..."
Listening as Minato listed the conditions one by one, the corner of Seiryū's mouth twitched. "..."
One needed talent in Space-Time Ninjutsu.
The amount of Chakra also needed to be sufficient.
At the same time, precise Chakra control was required.
It also required extraordinary reflexes, reaction speed, adaptability, and processing ability.
Finally, one also had to overcome the discomfort of space-time displacement.
Why the hell did this kind of technique require so many conditions?
S-rank Ninjutsu was not enough to describe the difficulty of the Flying Thunder God Technique. SSS-rank would be more like it.
These conditions alone could filter out 99.99% of people!
However, Seiryū did not feel that he could not learn it.
Currently, the only things he felt uncertain about were whether he had talent in Space-Time Ninjutsu and whether he could overcome the discomfort brought about by space-time displacement.
As for the rest.
It was a piece of cake!
This cheating player was full of confidence!
"Alright, now let's test whether you can adapt to the discomfort brought about by space-time displacement. Don't vomit on me, okay..."
Minato revealed a mischievous smile.
He casually threw a Kunai engraved with the Flying Thunder God Technique Formula...
Then, without waiting for Seiryū to reply, he placed his right hand on Seiryū's shoulder.
With a thought, he cast the Flying Thunder God Technique...
'Swish, swish, swish...'
Within a few short seconds, Minato took Seiryū and flashed back and forth through an area of the field.
It was as if afterimages had appeared on the field.
"..."
Seiryū only felt the scene before his eyes rapidly changing, jumping one after another.
In a short time, it changed more than a dozen times.
At first, there was some dizziness and nausea.
However, he quickly adapted to this feeling.
After that.
His brain operated rapidly, and his perception was passively released, capturing the subtle Chakra fluctuations of each Flying Thunder God Kunai...
His rapidly operating brain was like a precise computer, analyzing and processing all information and situations one by one.
Instant responses and the next step of action... these thoughts appeared in his mind.
There was no confusion, nor was there any inability for his brain to keep up...
Not far away.
The others, who did not disturb the two brothers, watched the scene in the field where they flashed continuously, leaving behind afterimages of the two.
They could not help but marvel.
The speed of the Flying Thunder God Technique was indeed very fast. The afterimages almost made them unable to distinguish reality from illusion...
Jiraiya stroked his chin and said, "I wonder if this kid Seiryū can learn the Flying Thunder God Technique? Since the Second Hokage developed this Space-Time Ninjutsu, only Minato has been able to learn it."
The difficulty of the Flying Thunder God Technique was extremely high.
He had also tried to learn it before.
However, he did not have that talent.
As far as he knew, only two people had learned the Flying Thunder God Technique!
With such a high-difficulty Ninjutsu, he did not know if Seiryū could learn it.
Kurenai spoke, her words full of trust in Seiryū. "Of course Seiryū can learn it. I have never seen a Ninjutsu that he couldn't learn. His talent is too strong!"
Shizune nodded. "I feel the same way."
Tsunade watched with her arms crossed. She was also very confident in Seiryū and said calmly, "It's impossible for it to stump him. He is simply a freak."
"And if he can't learn it, I suspect he will go and develop another kind of Space-Time Ninjutsu himself later..."
If one were to ask who knew Seiryū's talent best.
Besides Seiryū himself.
It would be her, the Sensei who had spent a long time with Seiryū day and night.
Was there any Ninjutsu this kid could not learn?
Not yet.
It was just a matter of whether Seiryū wanted to learn it or not.
Ninjutsu, Genjutsu, Taijutsu, Sealing Jutsu, Medical Ninjutsu.
There was nothing Seiryū was not good at.
Now, this Space-Time Ninjutsu should also be unable to stump Seiryū.
Even if it did stump him.
She felt that Seiryū would find time to develop another kind of Space-Time Ninjutsu that suited him.
One had to know that the unconventional technique, Kaidō, was created because Seiryū felt that the healing effect of ordinary Medical Ninjutsu was too poor.
It was a new Medical Ninjutsu he had spent some time developing himself.
Geniuses were unreasonable!
Kushina thought of the various new Sealing Jutsu Seiryū had developed and could not help nodding. "Jiraiya-sensei, Tsunade-nee is right. This kid Seiryū is simply a freak."
"I have never seen such a freakish guy. Compared to Seiryū, Minato really doesn't count for much."
"Even Minato could learn it, so how could that little freak Seiryū not learn it."
It was not that she was belittling her boyfriend.
It was just that Seiryū's talent was truly too freakish.
This point could be seen from when he practiced Sealing Jutsu.
No matter what Sealing Jutsu it was, the time Seiryū spent was less than her boyfriend's...
"Uh..."
After all, Jiraiya had not spent much time with Seiryū.
Although he knew Seiryū's talent was extremely strong.
Such confident words from these people still made him somewhat stunned. "Are you all that confident in Seiryū?"
Tsunade said noncommittally, "Of course. He is my most proud disciple!"
"He is also my disciple..."
"Hmph, if it weren't for the fact that he apprenticed to you first, I would have told you to get lost long ago. Don't come back to Konoha often in the future if there's nothing going on. I don't want Seiryū to be led astray by you!"
"..."
Jiraiya felt a toothache.
He could not help retorting, "How could I lead Seiryū astray? Don't pin unfounded blame on me, alright?"
Tsunade glanced sideways at Jiraiya, her tone serious and threatening. "In the future, if you want to find Seiryū, whether to teach him Ninjutsu or just to meet and chat, you need to notify me first. Otherwise... I'll break your bones!"
Jiraiya: "..."
It was clearly him who had accepted Seiryū as a disciple first, right?
He needed Tsunade's nod of approval to find his own disciple?
Who was the latecomer here!
Tsunade's attitude toward Seiryū inexplicably made him feel a sense of envy.
He also wanted to be valued so much by Tsunade!
"Mm..."
Kurenai cautiously glanced at Jiraiya, but in her heart, she gave Tsunade a thumbs up.
She also did not want Jiraiya to have too much contact with Seiryū.
Seiryū would be led astray.
She absolutely would not allow it!
In the field.
After casting the Flying Thunder God Technique dozens of times in a row.
Minato saw that Seiryū's expression was still normal, so he did not continue and chose to stop.
'Swish!'
The two appeared on the spot.
Minato looked at Seiryū, whose expression was normal, and could not help exclaiming, "To have adapted to the discomfort of Space-Time Ninjutsu without undergoing special training, you are much more impressive than me..."
Seiryū clearly had not undergone this kind of special training, yet he had completely adapted to the discomfort of space-time displacement.
"It was a bit dizzy at first..."
Seiryū slowly exhaled and smiled. "So, Senpai, does this mean I have overcome the discomfort?"
Minato nodded. "Yes."
Seiryū asked, "Then what should I do next?"
"Very simple."
Minato answered.
He continued, "The Flying Thunder God Technique works by locating coordinates and instantly shifting to the position of those coordinates. The longer the distance, the more Chakra is consumed."
"Whether or not you can perceive the location of the coordinates determines whether you have talent in Space-Time Ninjutsu. This is also the most critical step!"
"How do I do it? Is there a special testing method?"
"No."
Minato shook his head.
He explained the situation. "You need to first condense the Flying Thunder God Seal. This is the first step. The specific process is similar to the process of practicing Sealing Jutsu and burning Sealing Jutsu formulas that you have done before."
"You have experience, so it shouldn't be a big problem."
"After that, it is about sensing the coordinate location of the Sealing Jutsu formula you burned..."
Minato described the process of cultivating the Flying Thunder God Technique.
The Flying Thunder God Seal.
That was the coordinate for the Flying Thunder God Technique's positioning.
Burning out the Flying Thunder God Seal was the first step.
The second step was whether or not one could sense the specific location of the coordinate of the Flying Thunder God Technique Formula.
Burning out the Flying Thunder God Seal was also a difficult task for ordinary people, but with effort, it could be accomplished.
Whether one could sense the coordinate of the Flying Thunder God Technique Formula afterward was the key.
This was also the method to judge whether a person had talent for Space-Time Ninjutsu...
"No wonder so few people have learned the Flying Thunder God Technique. There are too many conditions, and every condition is difficult for ordinary people to achieve."
The more he understood the Flying Thunder God Technique.
The more Seiryū sighed.
To cultivate the Flying Thunder God Technique, its difficulty was truly absurdly high...
Minato smiled. "Otherwise, why would only the Second Hokage and I have learned and mastered it? However, I think a third one should appear. I don't think you are unable to master the Flying Thunder God Technique."
Seiryū shrugged. "I am quite confident in my talent. If I can't learn it, hmm, I'll just try to develop one myself."
If he remembered correctly.
It seemed that among Kidō, there were also techniques with effects similar to Space-Time Ninjutsu?
If he could not learn the Flying Thunder God Technique.
He could just "develop" one himself!
The corner of Minato's mouth twitched. "Uh, as long as you're happy."
This kid Seiryū's thought process was indeed different from other people's.
If he could not learn it, he would develop it himself.
Only this kid Seiryū had the confidence and tone to say such things.
But honestly speaking.
Hearing Seiryū say this, the thought that Seiryū could not do it did not even appear in his heart.
Instead, he felt that it was truly possible for Seiryū to develop a new Space-Time Ninjutsu himself.
This kid could not be viewed with common sense!
Suppressing this thought in his heart, Minato looked at Seiryū and smiled. "Next, let's first try to condense the Flying Thunder God Seal. The process is not difficult, and it is specifically like this."
Listening to Minato's explanation, Seiryū nodded. "I'll give it a try."
(To be continued.)
