Naruto: The will of fire has nothing to do with my Uchiha

It is no longer limited to stuffing small things into the Kamui space. It is too troublesome, and the goal will be single and obvious. After a long time, it is inevitable that it will be a bit deliberate. Maybe Obito will use the Samsara Eye to see some tricks when he is bored, and he will miss a move.

At the beginning of the march preparation, Sasuke asked Kakashi to try to use the Kamui Space to store miscellaneous and unimportant military supplies. Although Kakashi could only put things in and not take them out, it was ninjutsu training. This kind of operation was based on the rational thinking of the ninja and was reasonable in this time period. After doing it many times, Obito would probably ignore it.

After small garbage, small animals, large objects, and the remains of objects split by space switches, Sasuke now stuffed things into Kakashi's space, saying that he was "testing the maximum theoretical one-time absorption amount". After all, every use of Kamui is accompanied by a large amount of eye chakra consumption and physical burden, so doing so would be more cost-effective. Kakashi does not have Hashirama cells, so even if Sasuke provides most of the chakra, the eyes are on him, and the physical loss that the caster should bear is not reduced too much.

Sasuke's simplified Yin Seal made Kakashi stronger, but the continuous use of the Sharingan also left him in a weak state almost all the time.

Weakness causing Kakashi's safety issues? Obito is still alive, so Kakashi obviously has no safety issues.

However, Kakashi always looked tired, so it was difficult for him to take on the leadership role that needed to boost morale on the front line. "Hokage Guard" might have been Sasuke's position if nothing unexpected had happened, but there were too many accidents recently, so it was appropriate for Kakashi, a veteran, to continue to take on the responsibility. Tsunade naturally knew the reason, and her condition just looked bad, so it was convenient to have an old employee around.

"The Uchiha thing, about the Sharingan..."

After all, it involves the bloodline of a clan. The secret technique of the Sharingan is not as public as ordinary ninjutsu. Senju's ancient research results on Uchiha are also a secret of the village. Sasuke also fell out with Konoha and became independent. Tsunade must be aware of such things, but it is not easy for the people below to ask about it.

Kakashi was Sasuke's teacher and his status in Konoha was high enough that it was okay to ask him a few questions, but at the same time he was afraid of trouble, so it was only after a period of cooling off that he used the issue of training as an opportunity to figure out Sasuke's attitude towards Konoha.

"What do you want to ask?"

"After the three magatama evolves into the Mangekyō Sharingan, will the abilities of the two eyes be related? Are Uchiha Itachi's abilities, Amaterasu and Tsukuyomi, possessed by the two eyes separately, or does it have little to do with the left or right eye?"

"I wonder if my eye has other abilities."

We have to team up to fight the Uchiha, so we need to make up for it? It seems like something Kakashi can do.

There are no Uchiha people left, and the practice of Sharingan is very difficult for outsiders, and it does not pose any threat to the main family, so Sasuke has always been relatively open to Kakashi and will not hide anything about his practice.

“It should be related.”

"For all original Sharingan owners, as long as they have awakened the Mangekyō, they can continue to use the new jutsu they have acquired regardless of whether their eyes are still there or not. There is a difference in strength, and the pattern on the pupil is just an external manifestation of the new ability they have acquired."

"If it were an outsider, he would only be able to use the corresponding abilities in the Sharingan during the transplant period. As far as I know, the two eyes do have one ability each, so your Kamui ability is probably like this."

"But you can think of it as mastering a new chakra transformation and continue to develop various related usage methods."

Sasuke's explanation was not much beyond Kakashi's expectations. His recent use of Kamui was an exercise developed based on the derivative uses of Kamui.

Sasuke was a little excited because he thought Kakashi had figured out Obito's identity from Kamui, but the result was the opposite of what he expected. It's not that he couldn't take the initiative to say it, but Sasuke didn't have the excuse of foresight. In order not to cause trouble for himself, he was too lazy to think about it. It would be better to wait for others to discover it first and then give correct guidance.

To be honest, it's hard to associate Shenwei's ability to become immune to damage and his ability to open space rifts together.

"The Sharingan consumes too much energy, but this formation has greatly improved my usual abilities, and I can fight a protracted battle now."

"We have Uchiha secret techniques that consume more energy. You only have one Sharingan and you don't have the Uchiha bloodline, so it's basically a one-time skill. But it can be used to save your life at a critical moment."

"I'll tell you how to use it, and you just need to know it. I don't think you can practice these two moves."

It's just the usage of two ninjutsu, and the amount of information is very small. Sasuke can activate the Mangekyō Sharingan and use illusion to deepen Kakashi's impression.

"Izanagi needs to activate it in advance. If he uses his Sharingan once, he will be blinded. If Uchiha hits him on the head and then uses it again, he may go blind. This is a small problem. You don't have to worry about it since you only have one Sharingan."

"In addition to consuming a large amount of chakra, Susanoo also directly consumes the upper limit of vision. Almost every time you use it, your vision will be significantly reduced. The defense is very strong, but as an outsider, it is difficult for you to fully utilize it. The consumption is huge. I feel that it is not worth it. You can use it at your own discretion."

"Susanoo is simple to explain. You probably know some chakra mimicry techniques, but they are more focused on mental power and Yin-attribute chakra."

The illusion didn't last for a few seconds, but it took a little longer to digest the information received. After Kakashi sorted it out, his eyes became a little solemn.

"This, Izanagi. Does that mean that the Uchiha who started the war can't be killed just once!?"

"Ah, of course. Even though you just found out, the Senju and Uchiha fought before, so Master should know about this. All previous Hokage should know about this."

"...I'll go find her to confirm."

"Thank you for today's training!"

Kakashi, who was found out by Sasuke to be slacking off, was able to distinguish the priorities when things happened, and even took the initiative to return to his post.

After arranging matters in the rear, Tsunade also arrived at the base camp in the south of the Land of Lightning to join the group.

The dotted marks on the battle line ahead on the map have already outlined the outer contours of the Akatsuki base over dozens of kilometers under the command of the Raikage. Once the five Kages gather for another combat meeting and finalize some details, they can launch a general offensive.

Far away from the village, the war had not yet been fully ignited, so the waiting before that could not be considered busy.

After listening to Kakashi's concerns, Tsunade gave a positive response.

Although it was his duty, Kakashi's suggestion that he might be careless was somewhat annoying.

In the previous meeting, she had already "briefly" mentioned to the other Kages that the Uchiha had once appeared in a secret technique that might lead to resurrection. A lot of Konoha's information had been destroyed, so she would stop here. Anyway, she had fulfilled the requirement of sharing information among the five Kages.
