Uchiha Kei maintained his original life for the next period of time, and Uchiha Fugaku did not go back to him.

Although Uchiha Itachi was sometimes asked to visit Kei Uchiha, he basically pounced on it every time.

Uchiha Kai won't wait for him to come stupidly, not to mention that Uchiha Kai doesn't have the time and energy to teach him anything, so let Uchiha Kai tell him: think more, judge more, and use your own eyes to explore the source of facts?

Uchiha Kei doesn't have this idle time, he is now basically training with Kakashi every day, and even Kenta Imai and Hinata Aya didn't look for the two of them.

Anyway, there is no mission from above, so Uchiha Kei naturally will not have any contact with these two people.

The feeling and impression that these two people gave to Uchiha Kei was too bad, and I'm afraid that for them, Uchiha Kai gave them the same feeling.

Their relationship is really a bit like three magnets, none of them have been attracted to each other so far, and some have only expelled each other.

Playing against Kakashi, a truly genius ninja, has a lot of unimaginable gains for Uchiha Kei, but what makes Uchiha Kei depressed is that Kakashi's progress seems to be a little too fast.

Perhaps inspired and inspired by Uchiha Kai, he did pick up the knife again, and then began to abandon the crooked route in the original book and try according to Uchiha Kai's advice.

As a result, both Kakashi himself and Kei Uchiha were shocked to find that such a path seemed to be very suitable for Kakashi!

Kakashi was originally a decent swordsman, even if he seemed to have started to deviate a little after his father's death, but maybe he used knives more because of his age.

Now that Kakashi had only been a little over a month away from the knife breaking, he didn't feel any jerky when he picked it up again, and even this time he was stronger.

Because of Obito's Sharingan, Kakashi's insight is also growing rapidly, and it is clear that Kakashi will not waste Chakra without visual illusions, and he decides to take the insight of Sharingan to the extreme.

Of course, he didn't use swordsmanship completely, and he still took the proposal that Uchiha Kei gave him to heart.

Uchiha Kei had proposed some improvements to Chidori before, and later he also talked about combining ninjutsu and sword arts, so Kakashi has been trying and developing in this direction.

The result was that Kakashi and the two of them practiced together during this time, and then Kakashi really made something that gave him a headache in front of Uchiha Kai!

Looking at the short knife that bloomed with blue light in Kakashi's hand, as well as the strange burst acceleration and the sudden appearance of the Thunder Chakra, Uchiha Kei was also a little embarrassed by Kakashi this time.

If it weren't for the fact that Uchiha Kaiyou's chakra eye insight was stronger and his reaction speed was faster, I am afraid that the sudden acceleration would have directly defeated him.

If this kind of thing is placed on the battlefield, then it means that Uchiha Kai is afraid that he will die completely.

And Uchiha Kei also found that such a fighting style does not seem to be a big drain on Chakra.

Although Kakashi Chakra is still not much and has to support the Sharingan, it doesn't look like the guy in the original book who was paralyzed without fighting anymore - although he felt that this guy was pretending.

"Is this your new knife technique?" After the battle, Uchiha Kai sat on the ground and asked with some curiosity, "Your sudden acceleration is caused by the stimulation of the body's functions, right?" ”

"Hmm." Kakashi was also sitting next to Kei Uchiha, and he looked at the knife in his hand with a somewhat complicated mood: "I didn't expect it to succeed in one time, probably because Obito's blessing and Chidori were created by me, that's why it's like this, right?" ”

Come on, Obito isn't dead.

Uchiha Kei complained in his heart, but he didn't explain anything to Kakashi, he was more concerned about Kakashi's new sword technique.

Kakashi didn't have any intention of hiding it, maybe in his opinion, this was the result of him and Uchiha Kai working together, and Uchiha Kai has a writing wheel eye and a thousand birds, so sooner or later he can make a similar one.

Through Kakashi's explanation, Uchiha Kei also almost figured out the situation of this sword technique.

Kakashi's sword is forged from the same material as Kei Uchiha's, with the difference that his sword is still the short knife that belongs to his father.

This knife also has excellent chakra conductivity and compatibility, so he can use this knife to cooperate with chakra to release ninjutsu.

And Kakashi's battle mode is not very normal, he covers the knife with chakra, but in order to save chakra, he only covers a thin layer.

In addition to making his weapons sharper, this small layer of chakra also has some 'surprise' effects.

Once Kakashi catches the opportunity, then he can completely burst out of the thunder-attribute chakra in an instant, and with the active stimulation given to him by the thunder-attribute chakra, he can hit the enemy faster.

And the chakra that was originally covered on the knife can also be converted into thunder attribute chakra faster, this chakra can also completely paralyze his enemy, the key is that the enemy's body will also be destroyed by this chakra!

It can be said that this knife has three characteristics - outbreak, paralysis and destruction, and the enemy who is hit by this knife can basically be declared finished unless it is particularly strong.

In the original book, Yamato was also paralyzed and lay on the ground after being hit by Uchiha Sasuke's Chidori, so you can imagine how deadly this effect is for most ninjas.

Uchiha Kei touched his chin, Kakashi's transformation seems to be relatively good at the moment, and Kakashi has also made some more interesting things.

This is very much in line with Uchiha Kai's vision, using Kakashi's path to confirm his conjecture, and then absorbing Kakashi's essence as nourishment for his own growth.

Although the means are not above board, he is a 'life coach' without saying anything.

What's more, he thinks that Kakashi's move is very suitable for him!

This can be regarded as a successful start, Uchiha Kai believes that Kakashi will be able to do a lot of tricks in the future, and when the time comes, Uchiha Kai will slowly 'cut leeks' while maintaining or deepening the current relationship.

"By the way, do you have a name for this knife technique?" Uchiha Kei leaned against the tree, thought for a moment and asked.

"I haven't figured out a name yet." Kakashi touched his head, "But I think you could have named him, because it's all done according to your ideas, although I said I developed it." ”

"Shall I think of a name?" Uchiha Kei tilted his head, thought for a moment, and then asked slowly, "What do you think, what do you think of the name Rankiri?" ”
