Tobirama Senju: "Nicely done!"
Tobirama Senju: "My Forbidden Jutsu should indeed fall into the hands of Black-Framed Naruto!"
Tobirama Senju: "Hahaha~"
Ōnoki: "Tsk tsk, Third Hokage... just you wait."
Kurotsuchi: "Black-framed Naruto-kun's movements are so fast! I didn't see them at all!"
Nara Shikamaru: "He exploited the blind spots."
Minato Namikaze: The scroll of seals is real; it's different from the one the Naruto of this world took.
Uzumaki Kushina: "So that means Naruto can find the key to the seal... and also master Ninjutsu that can resurrect people?!"
No one in the chat room spoke.
But this was equivalent to silent agreement.
["So the Shadow Clone Jutsu... can reach such a level. As expected of Naruto-kun~" Sakura could still clearly hear the sound of her own heartbeat.]
["Naruto is special; this Ninjutsu only becomes this powerful in his hands."]
["Alright, you all continue your training."]
[Kakashi offered a word of comfort.]
[Of course, he wasn't comforting Sakura, but Sasuke, whose face was deathly pale.]
['Have you made Naruto your goal?']
['Then you will be in a lot of pain, Sasuke.']
[Kakashi didn't say much more; he just glanced at Sasuke before turning to walk toward Naruto.]
[At this moment, Naruto was organizing the memories and experiences sent back by his Shadow Clones.]
[In an extremely short amount of time, the Shadow Clones had a clear division of labor and memorized every single Ninjutsu on the scroll of seals.]
[And no one noticed.]
[Right now, he needed some time to sort through it all.]
['Four Symbols Seal? Eight Trigrams Seal... it's the same as the seal on my lower abdomen... Confirmed, it is the Four Symbols Seal, but it seems to be double-layered.']
['No rush. It'll be obvious once I go back and have the Great Fox send out some Chakra.']
['Multiple Shadow Clone Technique...']
[After entering a meditative state, Naruto's speed in sorting through this information increased significantly.]
[Meanwhile, with the Great Fox's reluctant help, he connected with the Shadow Clones inside the Sealing Space, achieving a short-term synchronization of memories and experiences.]
[Every time Naruto finished sorting a Ninjutsu, a Shadow Clone in the Sealing Space would record it on a scroll manifested from mental energy.]
[There were many, so many!]
[Naruto was inwardly shocked.]
[Second Hokage, Tobirama Senju... a grand talent! An absolute genius!]
[Genius was no longer enough to describe him.]
[And these were only the Forbidden Jutsu listed in the scroll of seals. If there were complete manuscripts and the like...]
[If the achievements of the First Hokage and Uchiha Madara during the Warring States period were to establish the structure of the Ninja World and the tone for future development...]
[Then the existence of the Second Hokage, Tobirama Senju, pushed the progress of Ninjutsu in the Ninja World forward by a hundred, or even a thousand years!]
[Before the Second Hokage, Tobirama Senju, physical clones like the Shadow Clone had never appeared in the history of the Ninja World.]
[Of course, the most important thing was the characteristics of the Shadow Clone.]
[There were too many aspects.]
['Edo Tensei?!']
[Naruto frowned.]
['S-rank Forbidden Jutsu, Otherworldly Summoning Jutsu?']
['Summoning Jutsu... signing a contract, summoning... summoning beasts?']
['Edo Tensei... resurrecting and controlling the dead?!']
[Naruto was stunned.]
[Truly stunned.]
[This sort of thing was simply inconceivable!]
[Even if Naruto had such thoughts before (questioning Fourth Hokage - Minato Namikaze and the previous Nine-Tails Jinchuriki Uzumaki Kushina), he would shake his head immediately. How could such a Ninjutsu possibly exist?]
[If it existed, then Tobirama Senju probably wouldn't have died.]
[As long as he used Edo Tensei to bring back his elder brother, even if it meant disturbing Hashirama Senju's soul... how could Tobirama Senju have been killed by anyone?]
[Killing his younger brother in front of the god of shinobi?]
[However, Naruto soon felt relieved.]
['It requires a sacrifice... could it be based on the secret techniques of my Uzumaki Clan?']
['It's probably not a perfected technique, though it can already be implemented. Given Tobirama Senju's abilities, this technique is definitely not that simple. It's likely because it disturbs the dead...']
['From this perspective, Tobirama Senju had a bottom line.']
['He's a respectable senior... it's just a bit of a pity.']
[In the Pure Land World, Tobirama Senju, who had originally been praising Black-Framed Naruto, turned dark-faced once again.]
"I knew it!"
"The naturally evil Uzumaki Naruto!"
"When mentioning me... praise me if you want, but don't bring up those four bastards every time, alright?!"
['Multi-Exploding Tag Technique... as expected!']
['This technique and the Shuriken Shadow Clone Jutsu share the same underlying logic!']
['Heh, I knew it. How could that Old Thing have developed such a powerful Ninjutsu?']
[Shaking his head, Naruto continued to organize the memories and experiences sent back by his Shadow Clones.]
['Eight Gates?']
['Might Duy... Might Guy... and Rock Lee.']
['This technique can be learned; it'll serve as a trump card.']
['Might Duy was a Genin who trained hard for twenty years, and his combat power was still that of an ordinary Genin. But after opening the Eight Gates, even the Seven Ninja Swordsmen of the Mist...']
Hidden Mist Village: "..."
Alright, stop talking about it.
['Evil Sealing Method... Fire Sealing Method... Reaper Death Seal?']
['There are so many... there are even many sealing techniques of the Uzumaki Clan inside. They must have been brought by the First Hokage's wife, Uzumaki Mito.']
['There are also physical techniques, Front and Hidden Lotus... snakes?']
['Could they be Orochimaru's techniques?']
['They seem to have a significant connection to summoning beasts... Orochimaru... one of the legendary Sannin, the living scientific research pioneer closest to Tobirama Senju in the Ninja World... perhaps if there's a chance in the future, I can find him through Anko.']
['His value is very high.']
['Edo Tensei... it has many conditions, but if the First and Second Hokage could be brought back through Edo Tensei... or even Uchiha Madara... that would be a huge profit!']
['Tireless, unkillable... free labor!']
Warring States F4: "???"
[Inside the Sealing Space, Naruto's Shadow Clone's eyes lit up.]
['Living Corpse Reincarnation... this technique is a bit wicked.']
[...]
[A long while later.]
[Naruto finally finished sorting through the contents of the scroll of seals one by one.]
[A small regret was that the Flying Thunder God Technique was not recorded in the scroll of seals.]
['Well, Flying Thunder God... a space-time Ninjutsu, the highest-level instantaneous substitution technique in the Ninja World currently. Even my Body Flicker Technique isn't dangerous, let alone the Flying Thunder God developed by Tobirama Senju.']
[The scroll of seals should really be called the Scroll of Forbidden Jutsu.]
[Suppressing the excitement in his heart, Naruto planned to practice them one by one.]
[At the same time, the idea of entering the Hokage Building to seize all the information grew deeper.]
[The Root Organization's underground base also had quite a lot, but at the thought of everything he had seen in the Root Organization's underground base...]
[Naruto gave a mocking laugh; it wasn't actually that surprising.]
[But it still made his skin crawl.]
[This Konoha Village was much darker than he had imagined.]
[Sakura, Sasuke, and Kakashi had been observing Naruto for a while now.]
[Sakura was very worried, as the Multiple Shadow Clone Technique was dangerous.]
[Fortunately, Naruto didn't show any signs of discomfort.]
[After waiting for a while, Sakura asked curiously:]
["Kakashi-sensei, can you do it?"]
["I can, but the Shadow Clones I produce probably wouldn't last three seconds, and then you'd be collecting my corpse."]
