The brows of Uchiha Jin furrowed slightly.
However, after thinking for a brief moment, he still grasped the sword while in his soul form.
This was not recklessness, but careful calculation.
Because even in his current soul state, he could feel his primordial tower, his greatest trump card for survival, still resting within his soul.
Therefore, he was confident that even if there was truly something wrong with this sword, the primordial tower could save his life!
He would take this opportunity to figure out exactly what this sword was.
In the next second, the moment the soul of Uchiha Jin grasped the sword, the blade in reality slowly dissipated and then appeared directly in the hands of his soul.
"This..."
In his current soul state, Uchiha Jin could feel the cold touch of the sword in his hand.
This could not help but shake his heart. A sword that a soul could use?
For a moment, he thought of the short sword held by the Shinigami summoned when Minato Namikaze used the Dead Demon Consuming Seal.
Did the sword in his hand belong to the same system as the short sword of the Shinigami?
[Ding, soul-type weapon detected!]
[Detection complete!]
[Asauchi: Initial form of a Zanpakuto.]
[The host has not yet cultivated soul-type weapons; this type of weapon cannot be used for the time being.]
[Searching treasures within the tower...]
[Search complete!]
[Complete Shinigami cultivation system detected; full infusion requires 10,000 Luck Points.]
[Perform infusion?]
Just as Uchiha Jin was pondering, the primordial tower proactively provided a prompt.
Asauchi? Zanpakuto? Were these not things from the Shinigami system?
How could such things exist in the Naruto world?
It was no wonder Uchiha Jin had not recognized this thing. After all, if the primordial tower had given him this sword, he would have surely realized the connection to the soul immediately.
But, the problem was... this sword was given by the Katsuyu of Shikkotsu Forest. Who would have thought that one could obtain an Asauchi in the Naruto world?
Now, the question arose! Was there some kind of channel in the Naruto world that could link to the Seireitei of the Soul Society?
And in that previous era before the Otsutsuki appeared, was the Shinigami within it part of the system from the Seireitei?
Was the image of the Shinigami he had seen just a weird, unrecognizable monster created after Hagoromo merged with it?
Countless thoughts gathered in his mind.
In an instant, Uchiha Jin thought of many things, but after a moment of contemplation, he pushed these questions to the back of his mind.
Because thinking too much was useless!
What he could do now was to cultivate and grow stronger as much as possible. When he grew to the point of being truly powerful, all the secrets of this world would naturally be revealed.
'primordial tower, perform infusion!'
Following the command of Uchiha Jin, the primordial tower in his sea of consciousness began to rotate. A golden light shot out, merging into his soul.
The mind of Uchiha Jin was instantly filled with countless memories.
From basic spiritual energy control and Soul Imprinting, to the subsequent Zanjutsu, Hakuda, Hoho, and Kido, and even Soul Burial training.
The history of the Soul Society: such as the organizational structure of the Seireitei, the Gotei 13, and so on; basic common knowledge about Hueco Mundo, Hell, and the Dangai; and even how to use common auxiliary items like the Soul-Communication Communicator and Gikongan.
Almost in an instant, Uchiha Jin grew from a Soul Society novice into a Soul Society veteran!
The next second, the soul of Uchiha Jin returned to his body. He briefly greeted Rin Nohara, then left Konoha directly and headed to the nearby Valley of the End.
He began to train in the basic Shinigami arts of Zanjutsu, Hakuda, Hoho, and Kido!
Swordsmanship? Average! In some respects, it was not even as good as the Uchiha-style swordsmanship.
Fist fighting? It was passable! At the very least, in the perception of Uchiha Jin, it was far inferior to the Konoha style of Might Guy.
Shunpo? Very good! It felt a bit stronger than the Body Flicker Technique, so he could practice it a little, but there was no need to invest too much energy.
For the current Uchiha Jin, even the Flying Thunder God could not keep up with his pace; he generally used Yomotsu Hirasaka now.
Therefore, the only thing truly worth his effort was the strongest aspect: Kido.
Only Kido could cause damage to the soul-type Shinigami Hamura, and it was also the immediate combat capability he currently lacked the most.
"O sovereign! Mask of flesh and bone, all creation, flutter of wings, ye who bears the name of Man! Scorching heat and turmoil, barrier of the sea, reverse-coiling towards the south, march forward!"
Uchiha Jin began to chant.
Although he was not in his soul state now, after a thought, the Asauchi emerged from the void and was grasped by Uchiha Jin.
'Hado #31, Shakkaho!'
Boom! A cluster of scorching fire shot out. Unlike the Fire Release of the Chakra system, Uchiha Jin watched the fireball before him and could easily feel a tremor of the soul.
This move was effective against souls!
Soren Zukusho, Raikoho, Kurohitsugi... One Kido ability after another was used. After a full two hours of training, the anxious heart of Uchiha Jin finally relaxed a little.
Although he could not achieve Shikai yet, at least he had some ability to engage in battle with Hamura.
For now, it was enough!
After finishing his training, Uchiha Jin returned home. He did not go to the room of Rin Nohara tonight, but instead went to a quiet room by himself.
"Soul Imprinting? Let us give it a try."
Uchiha Jin spoke slowly.
He sat cross-legged on the tatami, placed the Asauchi flat on his lap, and then used the ability of Soul Imprinting to carve his soul essence onto the Asauchi as much as possible.
However, after a moment, Uchiha Jin gave up, because this was a time-consuming process.
He had watched the original work of Bleach in his past life, so he understood that Shinigami and Naruto were completely different.
Normal Ninja in the Naruto world generally only lived for thirty-something years, and even during wartime, it was normal for children in their teens to die.
But what about Shinigami? The Shinigami inside often lived for hundreds or thousands of years. The conventional speed to achieve Shikai with an Asauchi was measured in decades—ten or twenty years—and some Shinigami with ordinary abilities even found it difficult to achieve Shikai after fifty or sixty years.
So, the question arose! Did he have that much time?
The Six Paths Sage Otsutsuki Hagoromo would be attacking in just over ten days!
After a moment of contemplation, he summoned the panel and used the reinforcement function.
[Detecting host's soul...]
[Soul particles are inclined towards the Fire element; the Zanpakuto's Shikai can only incline towards one direction.]
[Reinforceable Zanpakuto: Ryujin Jakka.]
[Reinforce to Shikai state: 100,000 Luck Points required.]
[Reinforce to Bankai state: 1,000,000 Luck Points required.]
Following the command of Uchiha Jin, the primordial tower quickly provided a reinforcement plan.
And after seeing the reinforcement direction, Uchiha Jin was stunned.
Ryujin Jakka? That strongest fire-type Zanpakuto?
