Fire style: Majestic Destroyer Flame.

After seeing the fully completed plan of action on the map all four of them realize that this plan needs a large number of shinobi compared to the shinobi available to them. So for the next hour, they debated again which clan to be incorporated into the plan for the plan to become feasible. The candidate for the clans were obviously the clans with good tracking abilities like the Hyuga for their Byakugan, Aburame for their insect handling, and Inuzuka for their ninken.

After seeing that night has gone on for a long they all bid farewell to each other in the fear of their wives and agreed to meet tomorrow also to discuss the next steps of the plans.

The next day.

Again the Ino-Shika-Cho trio and Fugaku meet each other to discuss the matter of Heaven's Net.

On the other hand in the training ground of Uchiha Itachi and Shisui are facing each other making the seal of confrontation.

The next moment Itachi lungs forward with the force to obliterate a tree and punches straightforward at the torso of Shisui just to see how Shisui's fighting power is now compared to the time he is introduced in Naruto, Shisui jumps back high up and takes out shurikens and throws them towards Itachi. Itachi takes out a kunai and deflects the incoming shuriken and in the meantime, Shishui is performing the hand signs for his Jutsu, seeing this Itachi immediately takes a step back and again dashes toward Shisui and this time he performs a drop kick aimed at the head of Shishui, Shisui blocks it with his hands and feels quite a power on his hands which are shaking just by blocking the kick of Itachi who is just 4 years old boy. Shishui changes his mind and starts to perform mid-distance fights like performing the substitution Jutsu at the last moment when the strike is to be connected and he repeatedly attacks with just shurikens and guided shuriken through the wire it was very annoying for Itachi to deal with it as he can't use more power because he can hurt Shishui if the power is not handled properly and the whole meaning of this spar is to make Itachi handle his power well. After a round of sparing Itachi increases his power slightly more so now he can obliterate 2 trees and also increases his speed now a quick fight was going on between Itachi and Shishui, Shishui would always evade at the last moment with his shunshin no Jutsu now as substitution is much slower compared to it and the increased speed of Itachi is not giving him enough time for it so Shishui starts using his shunshin no Jutsu. Itachi sees that the sunshin jutsu of Shishui is not at the level of forming clone bodies but it is still faster than his speed as whenever Shishui gets a chance he would counter Itachi with a punch or kick Itachi was able to easily take the punch and kick but it was making him angry as he was the only one who was getting beaten whereas Shishui was evading his punches and kicks. Itachi wanted to increase his speed and power even more but he reins his anger and frustration spars with Shishui till he is exhausted as Itachi with the body of Saitama has a lot of Stamina compared to any shinobi he is not much exhausted but Shishui is exhausted after sparing rounds of fight with Itachi both of them stops the spar with the seal of reconciliation and take a break. Shishui marvels at the body of Itachi because of the power Itachi can produce at the age 4 of and the stamina he has. Being silent till now Shishui talks first " that's quite a power you have but you are using it straightforwardly, it's okay for now but you'll have to properly learn how to fight from now on".

It's not my fault Itachi thinks because the only image of using the power of Saitama comes from Saitama only and his fighting style is straight punch and nothing else all of the fights is over by a punch so that image has stuck in my mind so it will take a lot of time to fight like a shinobi and there is nothing wrong by fighting like Saitama there are no cumbersome feints and techniques are involved it is just a showcase of pure unadulterated power to its peak.

"Okay, Shishui I will learn the taijutsu techniques," said Itachi. Itachi wanted to slowly cultivate a friendship between himself and Shishui so he is not proactive. Both of them rest for a bit and start another round of sparing.

In the afternoon they end their sparring session and leave for the day. This was the first day of the meeting between Itachi and Shishu. Itachi was observing Shishui and comparing him to the Shishui shown in Naruto he was very excited to meet one of his favorite characters of Naruto but he wanted to observe him before he went forward for the friendship because in anime all the sides of the character can't be shown as this now a real life so a person has all types of faces which he shows to the society some of it and other are deeply hidden within the other faces so Itachi can't just make decisions based on the anime. As in anime, the Third Hokage is shown very benevolent and kind Hokage who cared for his shinobi but by analyzing his character many people know what kind of a Hokage he is even having the power of Hokage he never punished Danzo for creating a mess all over the world and in Konoha. Even after knowing that Danzo had sent assassins after him he still talks to him like a friend and does not punish him. And in the name of the will of fire, he sacrificed many brilliant and loyal shinobi of Konoha like the original Itachi, Shishui, Hyuga Hizashi, etc.

Itachi had lunch with his mother and after lunch goes to study of his father there were 2 fire release jutsu scrolls kept at the top of the table Itachi picks one and sees the title ' Fire Release: Great Fireball Jutsu ' and the other scroll with the title of of 'Fire Release: Majestic Destroyer Flame' the same jutsu used by Madara to create the literal sea of fire which required several shinobi to use the Water Release Jutsu to stop it. Itachi picks up both the scroll and starts to read the content of the scroll he immediately acquires the Fire Release: Great Fireball Jutsu just by seeing through its signs and the way its chakra is molded inside the body, and for the Fire Release: Majestic Destroyer Flame he learns the signs easily but it takes some time to learn the way to mold the chakra inside the body but in no time he learns that also and in just an hour he learned two Fire Release Jutsu in which one was B-rank ninjutsu and the other one was C-rank ninjutsu. Fugaku had thought that Itachi will take a week to the C-rank ninjutsu and for the B-rank it would take over a month to learn it but here Itachi had learned both ninjutsu in just one hour now all that was needed was to use them just one-time to confirm how much he had learned and where should he correct his mistakes which he will make during the execution of the Jutsu.

After learning the content of the Jutsu from the scroll Itachi goes to the outskirts of Konoha where he finds a small lake with no one present, he checks the surroundings to confirm that no one is spying on him but there were the Anbu's sent by the Hokage and Danzo present who were watching the movements of Itachi. During sparring matches, they were not able to get into the Uchiha training ground so they had not seen the power of Itachi. Itachi with his Sharingan activated uses his full speed and arrives in front of all the four Anbu of Hokage and Root and cast a genjutsu on them so that they don't see what is Itachi is doing and know what has happened to them, afterwards he lightly taps over their heads making them faint there.

Now Itachi peacefully performs the Fire Release: Great Fireball Jutsu perfectly without any problems but the size of the fireball is thrice time big compared to the original fireball of the anime. Itachi contemplates over the reason for the fireball to become this big and after some time he comes to know that this is because of his massive chakra reserves which is the extra effect of having the Saitama body.

This time he performs the Jutsu again in a controlled manner and a normal regular fireball is released with just the one- third of the chakra required before.

Now Itachi performs the B-rank Ninjutsu Fire Release: Majestic Destroyer Flame knowing that if he fully unleashes this jutsu with his chakra reserve then he can create an even bigger fire sea compared to that of Madara, therefore, he controls his chakra very well and tries to perform the Jutsu with one-fourth amount of chakra required to perform the Jutsu but the flame of the sea was at the level of the pond only, so for the next attempt he perform the Jutsu with half the amount of chakra but even now there is no majestic feeling to the Jutsu performed so for the third attempt I increase the chakra to three-fourths of the chakra and now the Jutsu takes place in its majestic grandeur and becomes the sea of flame which could engulf the whole world if left alone, the surface of the lake water starts to evaporate and the steam is forming over the lake in just a few moments the whole surface of the lake is covered in the mist. It took around 15 minutes to clear the mist over the lake.

After seeing the effects of both jutsu being performed with less amount of chakra, Itachi feels excited and thinks to he should learn more ninjutsu to increase his strength as they are the means to expend his high reserves of chakra and will be useful in future fights and it is better to have many different ways of fighting then be used to only one style, that style can be analyzed if repeatedly used in battle and countermeasures can be used against it, in Saitama, the enemies are mostly monsters whose base instincts are to kill and subject humans but here in the shinobi world the enemy will be intelligent shinobis and aliens from the outer space(Otsutsuki) who will use their brains and collect the information about their enemies before starting most of the fights so it is better to have more styles of fighting than being using only one style. For taijutsu I have the power of Saitama which is my greatest weapon and asset. For genjutsu I have the sharingan which after awakening to the Mangekyou sharingan will give me Tsukyomi which is one of the best genjutsu in whole Naruto verse after Kotoamatsuki. And lastly for the ninjutsu I have a brains to learn them and I can ask father to show me the jutsu or I can acquire it from the clan library or through the village.
