Speaking of jealousy, it's naturally a joke, after all, compared to strength, Kushina is still above Kakashi and Obito.

Jiu Sinai's own strength is at the elite ninja level, and she is especially proficient in the art of sealing, plus she is the human pillar power of the Nine-Tails, and her ultimate strength is afraid that it can be compared to the three ninjas.

However, it is precisely because of the relationship between the human pillar and the power that although Jiu Sinai is very powerful, she is almost not allowed to go out of the village and go to the battlefield or something more impossible, because without the control of Mu Dun's technique, it will be a dangerous thing for her to have any accidents outside the village.

Kushina showed Kakashi and Obito the various points of the art of sealing the evil seal, and both of them tried to copy this technique with the Writing Wheel Eye, perhaps because the two of them had not yet reached a certain high level of copying the Writing Wheel Eye, or because advanced techniques such as seals could not be easily copied, and the two of them finally succeeded after several attempts.

However, compared to the ordinary learning method, the efficiency of copying is still amazing.

During this period, Kakashi and Obito also exchanged experiences in the use of the Sharingan, and if Kakashi encountered any questions, Obito also gave answers, after all, Kakashi is not of the Uchiha bloodline, and there will inevitably be problems in the use of the Sharingan. Although Obito has denied to Fugaku the idea of taking back Kakashi's writing wheel, even Fugaku has indirectly admitted that Kakashi can have writing wheel eyes, but when it comes to the use of writing wheels, there is no second person other than Obito who can help him.

First of all, one thing is for sure, Sharingan will definitely help Kakashi, because there is no doubt that Sharingan will improve people's abilities, and without Sharingan, Kakashi would not be able to use Chidori.

It's just that for Kakashi, his own chakra amount is not so sufficient, and he doesn't have a body of the first generation of cells, so the chakra also has considerable side effects for Kakashi.

Because of the relationship between the writing wheels, this also leads to Kakashi in the original book having an extremely high upper limit and a very low lower limit, which is called Hachiki Gogokai.

The reason for this is because in the original book, because Obito "died" early, Kakashi has always been isolated on the issue of writing wheels, and he didn't use them well, because no one will help him except Obito.

In fact, on the way back from the battle of Kannakun Bridge this time, Obito found that Kakashi had changed significantly, he would take the initiative to talk to Obito, and he would deliberately stop mentioning things like rules, which can be regarded as a "return" in a sense.

Obito always felt that Kakashi, who had closed himself off, was not the real him, and after the death of his father, Hachiki Soshigeru, he just put on an invisible mask for himself.

After the twists and turns of life and death, Kakashi regains his faith in his father's choice and begins to re-identify with things outside the rules of the world.

Of course, Obito also has more identification with Kakashi.

Although Obito didn't want to give Kakashi eyes at first, giving eyes was just out of helplessness in the moment of life and death, but now seeing Kakashi's changes, Obito also feels that it is worth it.

And he also accidentally obtained the reverse god of his left eye.,For his previous choice,Obito doesn't regret it.。

Obito's writing wheel eye is not the end of it for Kakashi! On the issue of writing wheels, Obito also wants to further help Kakashi, help him really master and use the writing wheels, and don't want him to become a flag tree Kakashi who opens up when he sees people.

It is important that the Sharingan does not affect Kakashi's self-growth, and on top of that, the Sharingan can also provide him with great help.

I believe that in this case, Kakashi will definitely be a grade or two better than the original.

Just imagine, if Qimu Sumao had a writing wheel eye with no side effects at all, how strong his strength would be.

Of course, it's impossible for the Sharingan to be completely side-free, and even the people of the Uchiha clan can't do this, let alone others.

What Obito wants to do for Kakashi is to find a way to minimize the negative consumption of his writing wheels.

The best solution is for Kakashi to freely control the opening and closing of the writing wheel, and when the writing wheel is not in use, the writing wheel can be converted to the state of the normal eye, so that there is no consumption at all.

However, this method is definitely not good, because the optic nerve connects to the brain, and the brain opens and closes the eyes by himself, and the eyes open by himself when he thinks about it, and then he closes the eyes by himself, and there is no bells and whistles to talk about at all.

Kakashi's brain can't control the switch of the eye, which in itself is something that is difficult to change, unless it is a transplant of the brain nerves of the Uchiha clan, but ...... Obviously, this is not realistic, and it may not be successful.

Before these few days, Obito didn't have any ideas, but after learning the sealing technique with his wife Kushina for a few days, Obito suddenly thought: since Kakashi can't "automatically" control the switch of the writing wheel eye through the brain, can he "manually" control the switch of the writing wheel eye through the sealing technique!

After all, if you unravel a seal that is not complicated, the time it takes is only one "unraveling" handprint, and for Kakashi, who is extremely fast, it will only take a second or two.

In exchange for a second or two to offset the continuous consumption of the writing wheel, no matter how you look at it, this is a profitable deal.

Obito thought that his father had used a half-familiar sealing technique to change the direction of the flow of chakra in his body, but that wasn't it, you could refer to a similar defense and use the sealing technique to change the direction of chakra towards Kakashi's left eye!

If the chakra acupuncture point that flows towards Kakashi's left eye is sealed, won't Kakashi's left eye be unable to consume chakra? Although this will cause Kakashi to lose sight in his left eye, Kakashi now basically covers his left eye with a forehead guard, so he basically doesn't use it in normal times.

And once it needs to be used, a seal of unraveling will unseal and allow the chakra to resume circulation, and then the writing wheel will naturally regain its light!

If you want to seal the magic spell, it's best to choose the evil magic seal, because the evil magic seal can seal the circulation of chakra!

In the original book, Kakashi used this technique to seal the "curse mark" on Uchiha Sasuke's body, and the "curse mark" itself is actually a kind of fairy chakra. If the Evil Seal can even be sealed with Immortal Chakra, there is no reason why it can't be sealed with ordinary Chakra!

The sealing technique of sealing the evil spell is not very difficult, and the seal of unraveling is not too complicated, both of them have learned it, and based on the current understanding of this sealing technique, Obito feels that it is completely feasible.

In the end, Obito explained his thoughts to both Kakashi and Kushina, and both of them agreed with Obito's suggestion.

Because Kakashi himself also thinks that the Sharingan is very powerful, but for him to keep it open like this, it is undoubtedly a huge consumption of continuous chakra, after all, even the people of the Uchiha clan dare not open the Sharingan all the time, unless it is a person with a first-generation cell.

"Obito, your idea is really good! In this way, without continuous consumption, Kakashi's body will store a sufficient amount of chakra, and if necessary, open the writing wheel eye, he will have a stronger explosive ability! ”

Kushina was very fond of Obito's proposal.

"Hmmm! That's what I thought! Obito said: "However, what Kakashi needs to seal is just a chakra into the eye, and the technique of sealing the evil seal is a bit troublesome, so I would like to ask my master if you can find a way to simplify the technique of sealing the evil seal, so that Kakashi will be faster every time he uses the chakra eye to seal himself and unravel!" ”

"Of course you can simplify the technique! Don't forget that this is Miss Ben's specialty! However, if the technique is simplified, the power will be reduced accordingly. Kushina said.

"It's okay, what Kakashi wants to seal is just an ordinary chakra that enters the eye, and the requirements for the power of the technique are actually not that high, and simple application is the first thing!" Obito said.

"Alright, give Miss Ben a day!" Kushina smiled and said confidently, "Come and gather at this time tomorrow, and I'll prepare a simplified version of the Evil Sealing Seal for Kakashi!" ”
