The man standing at the top of the ninja world

After reading the names of Nagato and Uzumaki Kushina, Fujita Takuto did not give Nagato a chance to speak. With a sway of his body, he was already standing on the sidelines.

He glanced at the students and said, "Okay, students, your respective combat partners have been assigned, and you can start fighting now."

Nagato: "..."

Ugh.

Nagato shook his head and sighed inwardly.

Although he knew that he could never be Uzumaki Kushina's opponent, the matter had reached this point and there was no room for turning around. He could only bite the bullet and fight with her.

The training ground was very large. Nagato and Uzumaki Kushina walked to an open space on the edge. Then they stood on one side, bowed to each other first, and then formed a seal.

The name of this seal is the Seal of Opposition. It does not activate ninjutsu. It is just a part of etiquette. After the battle, the two warring parties will form a seal of reconciliation.

These two seals are a tradition among ninjas. The specific meaning is that they can reconcile no matter how big the gap between ninjas is. Simply put, competition comes second and friendship comes first.

After completing the seal of opposition, Uzumaki Kushina raised her head, with an excited look on her face, and looked at Nagato eagerly. She had always been hostile to Nagato, and this time she finally had someone who could beat him upright. opportunity.

The next second, without saying a word, she just waved her fist and rushed towards Nagato.

Although this is just a simple competition, it is Nagato's first battle after coming to this world, and he must go all out.

He looked at Uzumaki Kushina rushing towards him, and his brain began to work rapidly. Ideas kept popping up and were quickly rejected.

What should I do if I can't fight him directly? My current strength is definitely not as strong as Uzumaki Kushina, and I will be completely defeated in a fist fight.

I am a ninja, and I have to use ninjutsu to deal with her, yes, that's it.

So, what ninjutsu should be used?

The clone technique is not good. The clone technique is not a shadow clone technique. The clone created has no entity and has no combat effectiveness at all.

The transformation technique is even more useless, let alone the ordinary transformation technique. Even Naruto's unique technique, the reverse harem technique that can catch Kaguya Otsutsuki, is impossible for a seven-year-old child. Girls work.

Then the only thing left is the Substitute Technique. Very good, just use the Substitute Technique to avoid Uzumaki Kushina's attack, and then find an opportunity to counterattack her.

After making up his mind, Nagato quickly formed seals with his hands and said silently in his heart: "Substitute"

However, what Nagato didn't expect was that before he could finish reciting the words Substitute Technique, Uzumaki Kushina had already rushed in front of him and punched him in the chest.

"Ah."

Nagato groaned, with a painful expression on his face. His upper body leaned forward slightly due to inertia, and his steps continued to retreat. Finally, his feet slipped and he stumbled to the ground.

Uzumaki Kushina frowned, looked at Nagato lying on the ground, and asked hesitantly: "Did you just want to use the Substitution Technique?"

The three body techniques are all basic ninjutsu. Although Uzumaki Kushina's chakra amount is not as good as Nagato's, it is still much more than that of ordinary ninjas. She had learned these three techniques a few months ago, so Although Nagato was reciting the Substitution Technique silently in her mind and did not shout it out, she still confirmed this from the hand seals Nagato made.

However, this discovery made her a little unbelievable.

"Yes."

Nagato covered his chest, which was still radiating pain, with one hand, took a breath, and nodded. Then he discovered that Uzumaki Kushina's look at him became very strange in an instant, like

It's like watching an idiot.

Before Nagato could figure out why Uzumaki Kushina looked like this, the next second, the latter blurted out: "Idiot."

Nagato rolled his eyes and said unhappily: "Hey, Kushina, even if I can't beat you, there's no need for you to curse."

"Hmph." Uzumaki Kushina snorted coldly, folded her arms, and looked down at Nagato, "You actually want to use the Substitution Technique to dodge my attack, what else is it if you are not an idiot?"

"What's wrong with the Substitution Technique? Isn't the Substitution Technique just for avoiding attacks?"

"To be able to say this, it seems that you really don't know anything about the Substitution Technique. It's a shame that you practiced it for so many days. It's all in vain."

"Theoretically, Substitution Technique can indeed evade all Ninjutsu. However, it also has its flaws, which are fatal flaws."

Nagato looked at Uzumaki Kushina in astonishment, "Fatal flaw"

Uzumaki Kushina nodded and said: "Yes, the disadvantage of the Substitute Technique is that its activation speed is too slow. Not only does it take time to form the seal, but it also takes time to find a substitute."

"If you are fighting an opponent who is much weaker than you, this flaw is nothing, because the huge gap in strength can completely make up for this shortcoming. But in a battle with an opponent of the same level, if you want to use the Substitute Technique to avoid attacks , you must predict in advance before the opponent attacks and use the substitute technique first, otherwise you will be seeking death."

"If you wait until the enemy attacks before using the Substitute Technique, it will be like before. Before you can find a substitute, the opponent's attack will have already hit you."

After listening to Uzumaki Kushina's words, Nagato lowered his head and murmured to himself: "Is this so?"

Uzumaki Kushina sneered, "Of course that's the case, otherwise why do you think the Substitute Jutsu is just the simplest E-level ninjutsu? If the Substitute Jutsu can really dodge any attack at will, let alone a mere E-level ninjutsu. Ninjutsu, even the highest S-level ninjutsu is not enough."

Nagato's face was gloomy and he fell into silence. After listening to Uzumaki Kushina's words, he had realized that he had fallen into a misunderstanding because of his training method.

In the previous training, he had been fighting against his shadow clone, and before the battle, he had already made a prediction in his mind in advance. The entire battle process was carried out according to the prediction, so when the shadow clone Before attacking Nagato's main body, the main body had already thought of a way to deal with it.

In other words, he had already completed the "prejudgment" before the battle, so he was completely unaware of the shortcomings of the substitute technique.

It was obviously impossible for Nagato to let Kushina Uzumaki attack according to his script, so he was caught off guard and defeated with one blow.

If this was not training with his classmates on the training ground, but fighting the enemy on the battlefield, he might have been instantly killed by the enemy in a single encounter because of this mistake.
