Facing Naruto's immortal mode, Kakashi had to use all his strength to directly enter the deeper mode of Thunder Escape Chakra.

With Sharingan assistance, Kakashi's use of this kind of ninja technique has completely surpassed the fourth generation of thunder shadows.

"If Naruto had learned the Wind Escape and Spiral Shuriken, Kakashi would probably lose now."

Xu Fan was still observing in secret and analyzing the gap in strength between Kakashi and Naruto.

This practical survival exercise has completely deviated from its original direction.

This is no longer a matter of whether the bell can be grabbed or not. Whether the seventh class can realize that the real purpose is teamwork.

Once Kakashi loses to Naruto after using all his strength, then as a responsible ninja, he will lose credibility in this team.

Even if Naruto himself doesn't care about this, Sasuke and Sakura will look down on Kakashi.

This is not part of Xu Fan’s plan.

But the situation in front of Kakashi is not optimistic.

Whether it was him or Naruto, Xu Fan knew very well about their intelligence.

Kakashi now undoubtedly takes it seriously and goes all out to defeat Naruto.

Because of the problems he noticed, Kakashi must have known them very well.

He can't lose or afford to lose this exercise.

Secondly, Naruto now only used the Immortal mode and has not used the Nine-Tail Chakra yet, and has entered the Golden Body mode.

One uses all his strength, the other is at ease.

The situation is naturally unfavorable to the former.

"Stand-in-One."

Xu Fan's eyes were slightly condensed, so he had to leave the matter of his coming to sign in and concentrate on the battle between Naruto and Kakashi.

Once Kakashi fails or even fails, he can only use a substitute technique to exchange with him.

“Really.”

Xu Fan took a deep breath, but he didn't expect that the situation would develop to this point.

As for Sakura and Sasuke.

After seeing Kakashi and Naruto's battle, he was not only shocked by Naruto's power, but also felt like he was impacted by the worldview.

Especially Sasuke.

When he was in Ninja School, he was the first in the class in all aspects.

He is from a famous family like the Uchiha clan.

In actual combat, he is undoubtedly much stronger than Sakura, and his understanding of ninja is far better than Sakura.

But now...

However, Sasuke felt that his understanding of ninja was completely collapsed.

Is this a ninja?

Is this ninjutsu?

This is clearly a magic trick!

Even though he widened his eyes and tried his best to capture Kakashi and Naruto, he could not keep up with their speed.

They were like a gust of wind, and after completing the confrontation at one place, they would immediately turn to the other side.

For a moment, thunder sounded.

Not to mention rushing up to use Naruto as bait to seize the bells on Kakashi's body, in this situation, he couldn't even catch up with them.

Not only that, every time Naruto and Kakashi collided, they would produce an impact and spread around.

If you are not careful, you will be affected, repelled, or knocked away by them.

Sasuke could understand Kakashi somewhat, after all, he was the Uenin from Konoha Village.

As a supreme nun, it is understandable to have such power.

But Naruto has always been the tail of the crane in the class!

What kind of place is that place called Miaomu Mountain?

Can you train a crane like Naruto so well?

"Damn it."

Sasuke gritted his teeth, his mood becoming more and more unwilling.

Why don’t I have such an opportunity and such power?

If you have such strength, you can catch up with the man and then question him why you did that!

“Chakra is passing…”

Kakashi closed his right eye directly and used the Sharingan on his left to observe Naruto, but noticed that his magic chakra was passing by rapidly.

Although Naruto is very powerful in this mode, it consumes chakra's technique very much.

According to his own analysis, at most three minutes, Naruto will be forced to remove this technique because of insufficient chakra.

"So that's what it is..."

Kakashi suddenly realized.

Any technique has weaknesses and risks to take.

Naruto's weakness is battery life.

It's just not clear whether Naruto can enter again after this technique is lifted.

"I see."

Kakashi's voice was quiet, and his body no longer fought with Naruto head-on. He stepped back and blocked Naruto's attacks one by one.

Although he is not as good as Naruto in terms of strength, he is not as good as himself in terms of speed.

"Your technique is indeed very strong, Naruto, but there are weaknesses."

This feeling made Kakashi feel very subtle.

On the surface, this is an analysis during the battle, but in fact, he is talking.

"If I guess correctly, this technique can't be maintained for a long time because it consumes a lot of chakra. At most three minutes, your body will be forced to remove this technique."

"I'm not right?"

Kakashi asked, rolling his throat.

In fact, Kakashi knew very well that insufficient battery life was not only a problem with the Immortal mode, but also his own weakness.

When the thunder escape chakra mode is fully turned on, the Sharingan is used again. At most, five minutes, your chakra will be consumed.

"It's really Kakashi. You even discovered this." Naruto was stunned at first, then praised Kakashi.

This is also due to Naruto's personality.

At the same time, he did not regard Kakashi as an enemy, and in his opinion, it was just an exercise.

Even if you tell Kakashi, it doesn't matter.

"really……"

Kakashi couldn't help but feel very complicated, and he was a little amused and crying.

This means that Naruto's thinking is relatively simple.

If it were Sasuke, he would not only not have the answer so simply, but would even be misleading.

After all, for ninjas, the key to victory or defeat is often the competition in intelligence.

Just like Naruto's technique.

Once this is confirmed, nothing is difficult to deal with.

Your own Thunder Escape Chakra mode can last for five minutes. Just drag the time to Naruto to remove the Immortal mode and you can grasp his flaws.

Suddenly, Kakashi seemed to suddenly realize something.

Just when he trapped Naruto with the technique of beheading in his heart, he became very quiet for a while.

I don't know if this is related to entering immortal mode.

"If I'm not mistaken, it will take some time for you to activate this technique, right?" Kakashi asked again.

After receiving Naruto's answer, Kakashi was more focused on dodging and consuming the other party's chakra.

Sasuke and Sakura had no strength to intervene in this battle at all.

After a while, Naruto was exhausted by the immortal art chakra and was forced to remove the immortal mode.

"I finally waited."
Chapter completed!
