When he burst out with all his might, Kakashi's heart was also extremely shocked.

If he hadn't seen it with his own eyes, he wouldn't even believe that he would one day have such power.

The Thunder Chakra mode is a ninjutsu that greatly increases the caster's speed.

If you enter the second state, it is like real thunder and lightning.

Attacks generated at this speed will also increase in strength.

If you could have entered this mode back then, and crushed the rock with soil, why couldn't you crush it?

When he was chased and killed by the shadows of the Fog Ninja Village, why couldn't he escape with Lin's whole body?

For a moment, Kakashi couldn't help but feel a lot of emotion in his heart.

But no matter what, this is a real battle, although Xu Fan chose to release water, it does not mean that he simply acted as a sandbag.

Let Kakashi make a move.

Especially now in this situation, in the face of himself, Kakashi was the first to be distracted.

Boom!

Xu Fan directly pushed his chakra forward, and Kakashi, who was unexpected, only felt a sharp pain in his leg, and his thoughts suddenly returned to reality.

Now is not the time to miss Obito and Rin.

Kakashi forced his body to rotate one hundred and eighty degrees in mid-air, relieving the pressure on his legs, while his left hand pressed down on his right wrist, guiding Thunder Chakra towards the palm of his hand.

"Rachel!"

Hearing Kakashi's burst of applause, he attacked forward with all his might, while relying on the speed of the Thunder Chakra Mode, which suddenly increased Rachel's power.

In Kakashi's opinion, even Xu Fan didn't want to retreat with this move.

As Kakashi expected, although Xu Fan had cast a very strong chakra pattern, he was even better at his own Rachel, slicing Xu Fan's chakra and bursting towards his hand.

"Do you use Rachel in the Thunder Chakra mode, these two ninjutsu can indeed complement each other, but this direct attack method is okay against people who don't know you."

Xu Fan complained about Kakashi's attack while throwing it into his other hand, and at the same time, his right hand quickly went up, grabbed Kakashi's wrist, and threw him directly.

Boom!

With a muffled thud, Kakashi's body slammed to the ground, forcing his body to roll several times before it could stop.

The Rachel in his hand also gradually dissipated.

The power of this ninjutsu is huge, but the shortcomings are also very obvious.

Such a violent form of chakra simply cannot be maintained for a long time.

In other words, Rachel is a ninjutsu that seizes the opponent's flaws for a moment and rewrites the victory.

If you don't have Obito's writing wheel eye, it will be difficult to even complete this ninjutsu by yourself.

However, without the power of the Rachel level, he would not be able to break through Xu Fan's defense at all.

For a moment, Kakashi couldn't help but find himself in a dilemma.

"If you use Rachel, you can't create a flaw, and if you don't use Rachel, you can't break that barrier."

Suddenly, Kakashi frowned, as if he realized something.

"Could it be that Xu Fan is not simply testing at all, but wants to see how I will take advantage of that moment of opportunity in this situation."

Kakashi gasped at the corner of his mouth, as if he understood the point of this actual combat training.

After all, Xu Fan had told himself before that he was one of the ninjas he knew with very strong analytical skills.

However, the truth of the matter is the exact opposite of what Kakashi thought.

"Ugh." Looking at Kakashi who flew out upside down, Xu Fan couldn't help muttering in his heart.

Is it that you use your own chakra too much?

I can't even break my own chakra pattern.

Is Kakashi's strength so weak?

It's also the sixth Hokage.

"And the current Kakashi is only one less Kamui from Shippuden, and the others should be about the same......"

"No, now he still has a technique like the Thunder Chakra Mode......

The corners of Xu Fan's mouth couldn't help but gasp, and his heart was also shocked by the scene in front of him.

"Or is it not that Kakashi is too weak, but that I'm too strong?"

"But I'm just using chakra, I can't do it with my bare hands, can I?"

Well?

With bare hands?

It doesn't seem impossible.

"But then again, the Thunder Chakra mode, plus Rachel, if you open my body directly and don't use the chakra to defend it, it should be very painful, right?"

Xu Fan couldn't help frowning, according to his cognition, the world of Naruto should be regarded as high offense and low defense, and the power of ninjutsu seemed to be greater than the other.

But the defense of the ninja is not so exaggerated.

Except for the three generations of Thunder Shadow, all other ninjas can be killed by very ordinary ninjutsu.

"Why don't you strengthen it with the Immortal Mode?"

Xu Fan thought about it for a while, and simply absorbed some natural energy.

In any case, the strength of the immortal mode is the amplification effect on ninjutsu, and it is just a fist and foot attack, which is not very powerful.

Even Naruto in Immortal Mode kicked Payne Tendo head-on, or the latter was defenseless, and he failed to do any damage, which is enough to prove this.

"Huh?"

Kakashi, who noticed the change, also froze instantly.

After he carefully analyzed it, he found that Xu Fan had lifted the difficult chakra mode.

The current Xu Fan has almost no means, and he is standing there with flaws all over his body.

"What does this mean......"

Kakashi's eyes were half-squinted, and he carefully checked Xu Fan's condition with his writing wheel, but the information he got was the same twice.

But whether it is the writing wheel eye or the thunder chakra mode, it is the existence of rapid consumption of chakra.

According to Kakashi's calculations, he can maintain a thunder chakra mode for half a minute at most.

Although he didn't know what Xu Fan was doing, his time was running out.

Thinking of this, Kakashi decided not to waste any more time, and rushed over first, using the writing wheel eye to catch Xu Fan's flaws.

And without the chakra enchantment, he doesn't need to use Rachel to create flaws.

Boom!

The ground under Kakashi's feet suddenly shattered, and his body was like a delicate thunderbolt, rushing in front of Xu Fan.

As soon as he opened his eyes, he saw that Kakashi was less than an arm's length away from him, and at the same time, his right hand was even more five-fingered fist, attacking his forehead.

"This angle ......"

Xu Fan couldn't help but gasp, not because he was amazed at Kakashi's speed or strength, but because of the position of his abdomen, which made him feel the urge to kick it.

Before Xu Fan realized this, he had already raised his right leg and stretched it out neatly.

Boom!

With a loud bang, Kakashi flew straight out in front of Xu Fan. Diagram of the Avenue of the Heavens
