"The Flying Thunder God Technique is a technique I improved based on the Second Hokage's version."
Minato Namikaze spoke, "The prerequisite for learning this technique is having a talent for space-time."
"In this regard, Yuu, you are undoubtedly qualified; there's no problem at all."
He had tested Minamikawa Yuu back when he first took him on as a student.
In terms of Ninjutsu training, Minamikawa Yuu showed great versatility.
He not only possessed all five Chakra natures but also had a talent for space-time.
While he couldn't compare to Minato Namikaze, it was undoubtedly quite good.
At least he was much stronger than an average person.
To this, Minamikawa Yuu could only say that the value of the Ōtsutsuki body was still rising.
"Your conditions for learning the Flying Thunder God Technique are fine, but to use it to its full potential, you need another ability."
Looking at Minamikawa Yuu in front of him, Minato Namikaze said.
"Reaction speed?"
Hearing Minato Namikaze's words, Minamikawa Yuu asked thoughtfully.
"Correct."
Minato Namikaze showed a look of appreciation: "The Flying Thunder God is a space-time technique. It allows you to engrave a special Flying Thunder God Mark in other locations and then teleport through this technique."
"It sounds great, but if your reaction speed isn't fast enough, it could lead to terrible consequences."
"Terrible consequences?"
Minamikawa Yuu was lost in thought.
He roughly understood what Minato Namikaze meant.
When a Ninja faces an enemy, there's a high probability the opponent is constantly moving.
Assuming the Flying Thunder God Mark is engraved on the opponent, the position you appear in will also keep shifting.
This is where the importance of reaction speed manifests.
Because when you want to strike the enemy, the enemy will also strike at you.
In that moment, if the opponent's neural reaction speed is faster than yours, it could lead to disastrous results.
If it's a Flying Thunder God Mark engraved beforehand, the problem becomes even greater.
Because you can never know exactly what will appear on the other side of the mark.
If everything remains the same, that's fine.
But if an enemy or some other danger suddenly appears there, that's when the test begins.
In either case, it heavily tests the user's neural reaction speed.
The reason Minato Namikaze could dominate with the Flying Thunder God Technique wasn't just because of the technique itself.
His own neural reaction speed, which was almost unparalleled, was equally crucial.
If someone else mastered the Flying Thunder God Technique, while it would still be effective, it would never be as powerful as it was in Minato Namikaze's hands.
Just like the Second Hokage.
The Flying Thunder God Technique was a Ninjutsu created by the Second Hokage, yet the power it displayed in his hands was far inferior to Minato Namikaze's.
Despite also being a user of the Flying Thunder God Technique, the Second Hokage actually died at the hands of the Kinkaku Brothers.
Such a baffling outcome would have been absolutely impossible for Minato Namikaze.
In fact, this was true.
During the Nine-Tailed Demon Fox's Attack, if Minato Namikaze hadn't been intent on dying with his wife, Obito alone would never have been able to handle him.
"If the Flying Thunder God Technique is used well, it can become your ultimate trump card, but if used improperly, it can also bring you great danger."
Minato Namikaze said, "So before you fully master this technique, you also need to undergo some targeted training."
In terms of basic conditions, Minamikawa Yuu was quite excellent.
This was also true for his neural reactions, which were quite outstanding compared to ordinary Ninja.
But in Minato Namikaze's view, just this level was still far from being able to perfectly control the Flying Thunder God Technique.
Therefore, proper training was necessary.
"Actually, strictly speaking, Kakashi is also very suitable for training in this technique."
Watching Minamikawa Yuu train seriously, Minato Namikaze sighed deeply: "Unfortunately, his neural reaction speed is insufficient. Even if he learned the Flying Thunder God Technique, he wouldn't be able to achieve much with it."
Minato Namikaze was never stingy with the techniques he mastered.
Later on, he even taught his Flying Thunder God Technique to his personal guards.
If he was like that with his guards, how much more so for his own students.
Unfortunately, Kakashi was not suited for learning the Flying Thunder God Technique.
It was hard to say what his space-time talent was like, but his neural reaction speed was clearly not enough.
He couldn't even control the reaction speed for the Chidori he created himself, requiring the Sharingan gifted by Obito to perfect it.
If his own Chidori was like that, then the even more demanding Flying Thunder God Technique was out of the question.
Moreover, his Chakra reserves were likely insufficient as well.
That's right, the Flying Thunder God Technique also has massive requirements for Chakra reserves.
Minamikawa Yuu had already realized this.
Minato Namikaze seemed ordinary, but in reality, he was a 'Hexagon Warrior'.
He not only had profound mastery in Ninjutsu, Sealing Techniques, Summoning Jutsu, and many other areas, but his Chakra reserves were also much larger than ordinary people's.
Perhaps he couldn't compare to an anomaly like Uzumaki Naruto later on, but he was more than enough to put Kakashi to shame.
The Flying Thunder God Technique involves frequent self-teleportation, and the Chakra consumption during this process is also enormous.
Minamikawa Yuu felt that even he found it a bit strained to use now.
This was quite a terrifying realization.
One must know that his Chakra reserves were not small at all compared to ordinary people. After all, he had obtained a double portion of physical and spiritual energy and possessed a partial Ōtsutsuki physique; his Chakra volume was already considered vast compared to normal people.
But even so, he estimated that he was only barely qualified for the usage requirements of the Flying Thunder God Technique.
If he was like this, then Kakashi, as a famously Chakra-deficient individual, shouldn't even think about it.
He just wasn't suited for this technique no matter how you looked at it.
"Don't be in too much of a hurry."
Looking at Minamikawa Yuu, Minato Namikaze spoke with a smile: "You're still very young, and your body is still growing. You have plenty of time to train; there's no need to be so impatient."
Although they hadn't been together for very long, he already held Minamikawa Yuu in high regard.
To him, this was almost a perfect candidate for a successor.
Among his several students, Obito and Rin Nohara were gone, and Kakashi, due to his own circumstances, was not suitable to inherit his legacy.
Instead, it was the Minamikawa Yuu before him who was similar to him in every way.
Equally gifted across the board, with amazing talents in all areas, and possessing the excellent conditions to train in the Flying Thunder God Technique.
Even in terms of personality, the boy shared many similarities with him.
With such conditions, combined with outstanding judgment and management abilities, he was truly the best choice to inherit his mantle.
