The first requirement for the secret technique of lightning escape is to practice the changes in the properties of thunder, and it needs to be mastered to a higher stage.
Yu Ye was born with the chakra properties of wind and thunder, so it was naturally relatively simple to do this step.
As for the change of the nature of cultivation to a higher stage, it is not difficult for Yu Ye.
After all, Yu Ye's chakra amount has now reached the Jonin level, which fully meets the standards for practicing chakra properties changes, and Yu Ye's control over chakra is by no means comparable to that of ordinary people.
It didn't take long for Yu Ye to easily control the changes in the properties of thunder-type chakra at a higher level.
At this time, Yu Ye even wanted to develop Chidori without spending too much effort.
But Chidori needs to form seals, and the same goes for the upgraded version of Raikiri, which is not suitable for Naito. Naito only practices the thunder attribute to use it to strengthen his body.
The secret technique of body-building with thunder attributes is easier to practice than Yu Ye imagined. Perhaps it is because Yu Ye's body is already extremely powerful and can easily withstand the stimulation of cell activity by thunder and lightning.
Under this kind of practice, not only the physical strength, but also the speed of Yu Ye's neural arc reflection, that is, the body speed, was greatly improved.
And as the practice further deepens, the speed of strengthening is not just a little bit, it almost doubles Yu Ye's speed!
If Yu Ye's air-shattering continuous flash could only superimpose three shocks from three directions at the same time, now Yu Ye can do it five times!
Of course, this five times is also the limit. No matter how fast Yu Ye's speed increases, the power of the shock cannot exceed the limit of five times of instant brewing.
After all, the force of shock is not a force of speed, it is an upright and frontal crushing force.
In addition, the further increase in physical strength also made Yu Ye's shock power much stronger.
A full-strength punch with superimposed strange power, and A-level ninjutsu that shatters high-level power are no longer stressful.
An ordinary punch without superimposing strange power is almost as powerful as an A-level ninjutsu with intermediate power.
Now, for Naito, if you don't superimpose strange power, it's just a normal punch, and if you superimpose strange power, it's a serious punch.
After Naito's chakra reaches the Jonin level, the consumption of using strange power has become much smaller.
Practicing the body-building secret technique of Lei Dun brings a small enhancement to Yu Ye in all directions.
Although the first stage of practice has not yet been completed, Yu Ye is already looking forward to the second stage and the possible third stage, thinking about when he must go to the Kingdom of Thunder.
It took a month to complete nearly half of the first stage of training, and Naito finally couldn't shirk away from Sarutobi Hiruzen's order.
He had previously received the mission of secret infiltration and assassination, and Yu Ye had to put it off for a while because he wanted to practice the secret technique of lightning escape. Now that the Second Ninja World War is getting more and more intense, he can no longer put it off.
Moreover, it is not impossible to practice even while performing tasks.
Yu Ye's mission is very special. Instead of wearing a mask and cloak, he directly dresses up like an ordinary person in the Kingdom of Rain and blends directly into the Kingdom of Rain.
There are several targets for Naito, including many elite jounin from Amegakure Village, and even Sansho Hanzo!
However, Sansho Hanzo must have been directly ignored by Naito. This BOSS is still left to Konoha to deal with, or he and the Sannin will team up to fight it in the future.
Anyway, you won’t lose any equipment just by swiping it.
In addition to the ninjas of Amegakure Village who are the targets of Naito's assassination, the jounin of Iwagakure Village and Sunagakure Village are also among Naito Ye's targets.
In fact, Yu Ye also has the task of spying on intelligence.
Almost all aspects of tasks are combined together. This is the task of Yu Ye's special ANBU. Of course, because of this, it is extremely free. Yu Ye can use any method he wants to use to complete the task.
Soon, after Yu Ye tidied up, he left Konoha's camp.
In the end, I chose to follow the instructions of the mission, first dress up as an ordinary person from the Kingdom of Rain, and then sneak into the Kingdom of Rain, and then decide the next step based on the intelligence or collecting intelligence myself.
Naito still wanted to take this opportunity to see if he could get information about the Kusanagi sword that fell into the hands of the ninjas of Sunagakure Village, and then find an opportunity to grab the Kusanagi sword.
…
Not long after Naito left, a root ninja was reporting to Danzo in a hidden underground area of the Konoha camp.
Danzo narrowed his eyes, his gaze flickering.
"Did a person leave the camp alone, and he didn't wear a mask or cloak... What does this mean? Is it Sarutobi Hiruzen's secret mission?"
"But why should a brat like Yu Ye be allowed to carry out the task, and why should he be specially dragged into that department?"
As the Hokage's assistant, Danzo does not have the right to mobilize ANBU, but he does have the authority to view ANBU's information and intelligence.
However, within the ANBU, even he could not access information about that special department. The number of people in that special department was currently a mystery. He only knew that it existed, but could not obtain any information.
There are only two people who know about that special department, one is Sarutobi Hiruzen and the other is Hatake Sakumo.
And since Yu Ye was transferred into it by Sarutobi Hiruzen, all the news about Yu Ye has been top secret, and it is difficult for even Danzo to know what happened to Yu Ye.
So until now Danzo is a little confused and can't figure out Sarutobi Hiruzen's intentions. In his opinion, Naito is not qualified to enter that special department at all.
Even though Yu Ye is extremely talented, he hasn't grown up yet.
Maybe Hiruzen Sarutobi didn't grow up in order to better protect Naito.
Thinking this, a cold light flashed in Danzo's eyes.
"In that case, you might as well leave him to me, Sarutobi."
After muttering something, Danzo gave an order, and two root ninjas immediately appeared in front of Danzo.
"Shikachi Nara, Kurama Night Burial, you two are the best control ninjas, now go and bring Naito over, make sure you survive."
"yes!"
The two masked root ninjas bowed their heads to Danzo, and then Shikachi Nara directly picked up Kurama and left instantly.
Watching the two people leave, Danzo shook his head slightly, "The Kurama clan's health is really a serious problem. Even if Orochimaru tried to strengthen it with external force, it seems that it still failed."
"It's a pity that the ninja of the Yamanaka clan died a few days ago. Otherwise, it would be best to let the ninjas of the Yamanaka clan cooperate with Lu Chi. It seems that we will have to go to the Yamanaka clan again."
Thinking of this, Danzo thought of Naito again. This was a battlefield anyway, and it was normal for a few people to die.
And after Naito was controlled by him, he could let Naito sneak into Sarutobi Hiruzen's Anbu, that special department.
Coupled with Yu Ye's special, almost perfect blood inheritance limit, Yu Ye will definitely become the most useful tool in his hand.
