Why had Minato Namikaze earned such a formidable reputation during the Third Shinobi World War?
There was no other reason: he had mastered the Space-Time Ninjutsu created by the Second Hokage—the Flying Thunder God Technique!
Spatial movement was faster than any other means of travel, so Minato Namikaze had become the fastest in the Shinobi World in one leap!
Any enemy he wanted to attack could never escape, and even when surrounded, he could retreat with ease.
Other Jonin, and even Kage, simply could not defeat an opponent of the same level in a minute.
Minato Namikaze, however, could take advantage of the Flying Thunder God Technique to slaughter opponents of the same level outright.
One or two were easy enough, and when Minato Namikaze really got going, he killed dozens of enemy Jonin by himself in a single battle.
Those fierce accomplishments had prompted villages hostile to Konoha to issue this order: "If you encounter Konoha's Yellow Flash on any mission, you may abandon the mission immediately without penalty"!
That kind of treatment really spoke for itself.
Perhaps the First Hokage and Madara Uchiha had once received similar treatment, but this was the first time it had happened since their deaths!
It could be said that without the Flying Thunder God Technique, Minato Namikaze only possessed strength ranging from Elite Jonin to Pseudo-Kage, but with it, his strength soared in one leap to that of a powerful Kage Level fighter!
With more training and more powerful Ninjutsu, becoming a Super Kage Level powerhouse would also have been well within his reach.
Before the power scaling of the Hokage World fell apart, the only Super Kage Level powerhouse was Nagato Uzumaki, who controlled the Six Paths of Pain.
It could be said that if the Fourth Hokage had not died in the Nine-Tails' Attack, he would certainly have grown into a Super Kage Level powerhouse.
There was actually proof of this, too.
During the Fourth Shinobi World War, Minato Namikaze, brought back by Impure World Reincarnation, reconciled with the half of the Nine-Tails inside him and then used Nine-Tails Chakra Mode.
At that point, his strength was already at the Super Kage Level.
And the crucial turning point in Minato Namikaze's life was undoubtedly learning the Flying Thunder God Technique.
Only by mastering Space-Time Ninjutsu had Minato Namikaze been able to achieve his later glory and even beat Orochimaru, one of the Sannin and a disciple of the Third Hokage, to the Hokage Position.
Even if there had been a little underhanded dealing, it was mostly because of Minato Namikaze's strength.
Minato Namikaze's case showed just how much difference knowing Space-Time Ninjutsu made.
The same was even more true of Obito Uchiha.
Obito Uchiha's spatial ability came from his Mangekyō Sharingan.
His left Mangekyō Sharingan, the Sharingan he had given Kakashi Hatake, contained the offensive Dōjutsu Kamui, while his right eye was the Mangekyō Sharingan he had always used himself, containing the Dōjutsu Kamui Dimension!
The Kamui Dimension had a wide range of abilities. It could be used for spatial movement like the Flying Thunder God Technique, and he could also draw his body into the Kamui Dimension to achieve intangibility.
The principle behind spatial movement using the Kamui Dimension was simple: by opening its entrance and exit in different places and using the Kamui Dimension as a transit point, spatial movement was achieved.
Although it could be used for spatial movement, the Kamui Dimension's spatial movement actually had some drawbacks.
First, spatial movement involved complicated steps and was not as convenient or fast as the Flying Thunder God Technique.
Second, the destination had to be within Obito's chakra-sensing range, so it could not be used to move to any location in the world like the Flying Thunder God.
Those were the ways the Kamui Dimension's spatial movement fell short of the Flying Thunder God Technique, and also why Obito rarely fought using that method.
However, the Kamui Dimension also had something that surpassed the Flying Thunder God: another application of the Kamui Dimension—intangibility!
That was an utterly godlike skill!
Because intangibility made him immune to all attacks!!
His body entered the Kamui Dimension, which only Obito could enter, so naturally no other attack could harm him.
With that godlike skill, Obito had entered Konoha as though no one were there during the Nine-Tails' Attack and easily abducted Kushina Uzumaki, who was giving birth under layers of protection, and little Naruto. Only then did the events of the Nine-Tails' Attack follow.
Not only that, even when Minato Namikaze defeated him one-on-one because of the difference in their strength, he was still able to escape easily.
At the Five Kage Summit, he even treated the Five Kage as if they were nothing, threatened them and rescued Sasuke, and no one could stop him.
It had to be said that the concept of the Six Paths Level had not yet appeared at that time, and the five people at the Five Kage Summit were the strongest in the world!
Yet Obito still toyed with them, and they were completely helpless.
That was the power of intangibility, an application of the Kamui Dimension.
It could be said that if the Dōjutsu awakened by Obito's Mangekyō Sharingan had not been the Kamui Dimension but something like Tsukuyomi or Amaterasu, he would never have achieved what he did later.
Minato Namikaze would have killed him during the Nine-Tails' Attack alone!
There was no doubt about it.
So spatial abilities really were extraordinarily powerful.
Having one and not having one put people on entirely different levels.
That was why Wu Chen now exclaimed that Minato Namikaze no longer had to throw fights.
It was precisely because Wu Chen understood this very well.
