After returning to Konoha and resting for a few days, Kei Uchiha began to run to the forest where he had been training for the sake of training.

Ryoko Uchiha still has a big opinion on this, Uchiha Kai, this child is usually very quiet and well-behaved, but this child's relationship with himself and Keisuke does not seem to be very much like a parent and a child.

At first, Ryoko and Keisuke didn't feel comfortable with it, but after so many years, they got used to it, and all they could do was pour their greatest love into this child, and there was nothing good they could do.

They didn't care about Uchiha Kai's fame on the battlefield this time, although they were also very happy that Uchiha Kai had opened the Sharingan and was still a three-hooked jade, but they were more concerned about Uchiha Kai's physical condition.

However, as a father, Keisuke Uchiha is much calmer than Ryoko Uchiha, who has been on the battlefield for six years, and it is clear that Keisuke Uchiha feels that Keisuke Uchiha has his own judgment.

After all, no matter how powerful a ninja is, his body must also be healthy enough, and he himself is a good example.

Uchiha Kei walked towards the forest where he often trained, he wasn't sure if he was being watched, after all, Uchiha Kei really couldn't be considered a 'marginal person' now.

And Uchiha Kei also doesn't have the scouting ability of Kenta Imai and Hinata Aya, so Uchiha Kei can only temporarily give up going to the place where he stored his records to train and tinker with something else.

For example, Kakashi entrusted the wave feng shui gate to give him a thousand birds, this scroll containing ninjutsu and some of Kakashi's own experience, Uchiha Kai has not studied it well until now.

Uchiha Kai is naturally good at possessing fire attribute chakra, which can be regarded as a normal Uchiha performance, while the thunder attribute Uchiha Kai is not so certain.

However, the chakra attributes that a ninja is born with do not determine that he will only have these in the future life, and other chakra attributes can be learned and refined by himself.

Uchiha Kei doesn't remember whether Uchiha Sasuke's thunder attribute was acquired or innate, but Uchiha Kei remembers that he has done a lot of things relying on Chidori with thunder attribute.

Chidori's ninjutsu is really not such a simple thing, because this ninjutsu has both chakra nature changes and form changes, and it can be said to be a relatively comprehensive ninjutsu.

And the most interesting thing about this ninjutsu is that it is more like a prototype, and Uchiha Sasuke has developed a lot of things based on this ninjutsu.

Like something like Chidori-ryu, Chidori-sagi, Chidori-sharp, Chidori-Chihon, Kirin and the like, it can be said that this ninjutsu can be compared to Spiral Pill to some extent.

"It's really worthy of being a master and apprentice, and even the ninjutsu that he did is almost the same." Uchiha Kei couldn't help but think in his heart after reading Kakashi's information.

The Spiral Pill can indeed only be regarded as a rudimentary ninjutsu, even if its power itself is large enough, but its plasticity is very high, and it is definitely more than one category higher than Chidori.

Of course, this may also have something to do with the path Naruto Uzumaki chose, but the starting point of these two techniques has already determined their future continuity.

Spiral Pill is a ninjutsu without chakra attributes, which means that it is like a blank sheet of paper, and it is completely possible to create different effects according to different chakra attributes, but Chidori has already qualified.

"But compared to the Spiral Pill, Chidori's ninjutsu is more suitable for the Uchiha."

Uchiha Kai is not greedy, what suits him is the best, and it is clear that Chidori is not only suitable for himself but also for his own sharingan.

Thinking of this, Uchiha Kai simply began to train this ninjutsu.

This ninjutsu is actually not very difficult for Uchiha Kei, because when they were doing tasks together, Uchiha Kai had already recorded the operation of Kakashi Kakashi and Chakra by writing chakra.

Kei Uchiha is not a kind person, he can open his eyes and say nonsense after copying Kenta Imai's knife and say that he didn't, so how could he miss Kakashi's ninjutsu?

Especially when Uchiha Kai lacks this kind of 'decisive' ninjutsu, he will definitely not miss it so easily.

It's just that the Uchiha Kai copy is a copy, but it is really embarrassing to find that it is not needed, there are too many things involved, and he has no time to solve it on the battlefield.

Otherwise, after obtaining this scroll, Uchiha Kai will be able to practice well, and he will not wait until now to take his time, which can be regarded as Uchiha Kai's helplessness.

Learning and practicing ninjutsu is very time-consuming, and the place where Uchiha Kei spends the most time is still obtaining the thunder attribute chakra, and the change in the nature of the thunder attribute chakra.

In the original book, it took Sasuke more than ten days to do this, and Uchiha Kai thought that his talent might not be as good as that of this unborn imp, so he was not in a hurry.

If there were really some big difficulties, it would be a big deal for Uchiha Kai to go to Konoha Hospital, and Kakashi would still be lying there to recuperate anyway.

Time passed day by day, and good news continued to come from the front line, which was also expected by Uchiha Kai.

The Kamino Bridge was blown up by himself, so the supply line and backup line were cut off, and at the same time, his own country had to face a group of crazy people, and the Iwa Shinobi of the Grass Country was already a lonely ghost.

It's just that what makes Uchiha Kai feel strange is that since the last time Uchiha Jun and they looked for him, he hasn't bothered himself anymore, as if Uchiha Kai doesn't exist.

But that's fine, Uchiha Kei didn't like them in the first place, and if they didn't come to him, Uchiha Kai wouldn't go to them at all, at least now Uchiha Kai wouldn't take the initiative to look for them.

What Uchiha Kai has to do now is to master the ninjutsu of Chidori, so that Uchiha Kai can be regarded as having a ninjutsu that can decide the outcome at a critical moment.

Although Ryoko Uchiha was very dissatisfied with Kei Uchiha's training, she really didn't say anything, but every night she would give Kei Uchiha a dressing on his right hand to help Kei Uchiha recover better.

"Chidori!"

After half a month of training and practice, Uchiha Kai also gradually solved the problem of thunder attribute chakra and its qualitative change, and I have to thank Kakashi for the information provided to make Uchiha Kai have such speed.

With the seal of Uchiha Kai, soon his right hand was covered with arcs that kept wandering, and the arcs were gathering more and more Uchiha Kai frowned a little, these arcs were not easy to control at all.

However, Uchiha Kai didn't take it too seriously, and as Uchiha Kai's eyes turned scarlet, the coordination and control of his body suddenly became stronger.

And these arcs, which were originally not obedient at all, also became honest at this moment, and as Uchiha Kai continued to control the large thunder chakra on his right hand, a sound similar to a bird's cry came from the chakra.

This sound made a smile appear on the face of the Uchiha Kei, and soon the bird calls became more and more, and the sound became higher and clearer, one, two...... Ten, twenty...... 100, 200...... It's like thousands of birds chirping at the same time, and the sound spreads more and more.

"You'd better come out now, or I can't guarantee that this spell won't fall on you." But at this moment, Uchiha Kai suddenly deviated slightly, and said in a cold voice.

The person who is hidden, Uchiha Kei, may not be able to find it, but the person who does not hide it at all will not pretend not to see it.

"It's a ninja who came down from the battlefield, and he's very sharp, Kei-kun." As soon as Uchiha Qi's words fell, Uchiha Jun slowly walked out from behind the big tree and complimented: "Don't get me wrong, I'm not peeking at you practicing ninjutsu, but I have news for you." ”

"Say."

"The patriarch is back, and he wants to see you."
