During Naito's training time, he always focused more on physical strength than anything else, so he came up with a new type of teleportation technique based on his physical strength.
There are few teleportation Jutsu in the ninja world, the most famous being the Flying Thunder God Jutsu, which does not require hand signals.
This Jutsu proved to be very useful on the battlefield.
Besides the Flying Thunder God Jutsu, there are many other Jutsu, such as Suna-Shunshin (Sand Flickering Body), Kiri-Shunshin (Mist Flickering Body) and Mizu-Shunshin (Water Flickering Body), but they all require one to perform hand seals every time they are used.
In short, there was everything.
If Naito were to fight a Jounin, he would certainly kill him, but if the Jounin were to use Shunshin no Jutsu (Flickering Body Jutsu), it would take a little longer to kill him.
And if a Jounin or an Elite Jounin specialized in Shunshin no Jutsu (Blinking Body Jutsu), he still could not escape from being killed by Naito, but it would take Naito a long time to kill him.
"Soru is a body technique that allows users to move at extremely high speeds by kicking the ground at least ten times in the blink of an eye, but it requires extreme physical strength, and even with my current physical strength it is very difficult to do," With his head bowed, Naito muttered, even after having fully trained the first stage of the Lightning Element Chakra Mode, he was still failing to use Soru.
After all, by being able to use Soru, one would eventually be able to use Geppo, which allows one to walk on air, and in the ninja world, only Might Guy after opening the Death Gate of Hachimon Tonko managed to do so.
Although the physical strength of ninja was much greater than that of civilians, but, still, it was not enough to use Soru.
Thus, Naito gradually gave up developing such techniques that rely purely on physical strength, and instead thought of combining chakra and his physical strength to develop an instantaneous movement Jutsu.
And, little by little, Naito also began to feel inspired and had some ideas in mind.
His shock power, a violent and tearing force, basically did not have much effect on his own body's momentum.
So it was almost impossible to develop an instantaneous movement Jutsu by relying on his Kekkei Genkai.
But instead, Naito had another trick up his sleeve, and that was the Brutal Force Jutsu.
The Brutal Force Jutsu is, without a doubt, a Jutsu that is capable of increasing the impact of an attack, but this Jutsu is not only limited to use on his arms.
Taking a deep breath and slowly applying chakra to his feet, Naito kicked the ground with that force and muttered, "Soru!"
CRACK!!!
The ground instantly cracked under his feet, while Naito's body jumped forward unexpectedly.
Despite his speed, he was actually no faster than when he was running at full speed.
After stopping, Naito frowned slightly and muttered, "No, the speed didn't improve much, the impact was a bit muffled and lost most of its power."
In the back, Tsunade's voice came from inside the hollow of the tree, "What happened!?"
"Nothing, I'm developing a new Jutsu," After she explained, Naito went back to deep thought.
The Brutal Force Jutsu, in essence, consisted of using chakra to amplify the force of impact.
But the effect was not great.
And what Naito needed at this point was to concentrate chakra at one point so that he could use the explosive power of the Jutsu to move at high speeds from one point to another.
Therefore, Naito needed to slightly modify the way he used the chakra of the Brutal Force Jutsu.
"I'll try again..."
Auge!!!
Naito once again moved quickly, and the movement speed obviously improved, but it wasn't fast enough.
"Again."
After trying again and again, a dozen times in a row, Naito slightly corrected some mistakes when using chakra, and his movement speed started to have a noticeable increase.
It seemed that he had found the right direction.
When he stopped again, joy appeared on his face, and he was about to keep trying when there was a sudden movement behind him.
As keen as Naito's senses were, he naturally perceived it in an instant.
He turned sharply and looked behind him, but then frowned as he saw no sign of anyone behind him.
"Strange..."
With a few surprised looks on his face, Naito looked down at his feet.
At this moment, the ground around him was crumbling everywhere under Naito's constant practice earlier.
After looking at the ground for a while, there was still no sign of movement, so Naito shook his head, and just when he thought it might be an illusion, suddenly, there was movement in the ground.
"There's something underground!"
With a sharp look on his face, Naito lifted his leg and it was no longer covered by the chakra from the Brutal Force Jutsu, but changed to a halo of white light.
However, just as he was about to kick the ground, the sound of Tsunade's shouting from the hollow of the tree stopped him, "What the hell!?"
Auge!!!
A boom was heard, not the sound of Naito's foot landing on the ground, but the sound of Tsunade hitting something with the Brutal Force Jutsu that blew the tree into the air.
The next moment, Tsunade stepped out from inside the hole of the tree, frowning as she looked inside.
However, in doing so, Naito froze and the shock power in his feet dissipated instantly, looking stunned at Tsunade.
But Tsunade didn't notice anything, her eyes still holding a stern gaze, watching the hole in the tree in front of her, fists clenched, ready to strike again.
And in the next moment, the hole in the tree in front of her suddenly exploded, and then a strange head popped out of it.
Tsunade, who had been a bit surprised by the sudden encounter, did not look frightened or anything like that when she saw the strange creature appear again, but clenched her fist with a cold face.
Who cares what kind of creature it is, if it dares to disturb her, it will get punched first!
However, before Tsunade could strike again, the strange creature opened its mouth and spat mist at Tsunade.
Woo!!!
In an instant, a dark purple poisonous mist came out of the creature's mouth.
Tsunade didn't expect that thing to use poison, so she stopped her fist and stepped back with sudden force.
She backed up quickly, but didn't forget to warn Naito, "Retreat! The gas is poisonous!!!"
"Uh... well," Naito had been looking at Tsunade in a somewhat dazed manner during this process, and only when he heard Tsunade's words did he unconsciously nod and back away next to Tsunade.
It was at that moment that Tsunade realized that something was wrong with Naito and looked at her with a stunned expression.
But the next moment, she understood.
In order to heal the wounds on her body, she had taken off all her clothes, and when the monster suddenly burst from the ground, she didn't even think about her clothes, but slipped out from inside the tree hole with a direct hit.
In other words.
Tsunade was completely naked in front of Naito.
Tsunade slowly lowered her gaze and then raised it again and stared at Naito.
Naito coughed rather awkwardly and said, "This... actually, I didn't see anything, my vision isn't very good these days."
Tsunade: "..."
The next moment, Naito took off his cloak and threw it towards Tsunade.
Tsunade caught it and covered his body, she didn't care much about Naito seeing her body, the most important thing right now was the poison gas in front of them.
Seeing her reaction, Naito did the same to save himself from the embarrassment of the moment and looked at the poisonous mist.
