"What you are doing is preventing souls from reaching the Pure Land and turning them into a weapon. Worse, the material you chose is Mōryō's body, a weaker Evil God from the previous era that escaped being hunted down and later mutated after merging with the chakra of others.
Even without merging with its original soul, with the influx of hundreds of thousands of souls, it will sooner or later awaken consciousness. And it will definitely not become a good or controllable God.
With so many strong souls merged into it, even I am not sure I could control it completely. Furthermore, neither you nor I know the ancient purification methods, and we cannot use the Sacred Tree to absorb its magical power once it is destroyed.
So once it goes out of control, with its Six Paths-level strength and corruptive magical power, it will become a greater disaster than anything the Ninja World has ever seen."
Hearing this, Itachi fell into deep thought. Although he was confident that his weapon would not go out of control, if even the Sage of Six Paths was unsure whether he could properly control it, then he had to take the matter seriously.
"Then, what do you suggest we should do?" Itachi inquired. He couldn't return empty-handed, right? At the very least, he should receive a Rinnegan or two as compensation.
"Of course, stop the process and seal it. With your Fūinjutsu being at the same level as mine, sealing a... what do you call it... Super-Kage level being should be easy." Hagoromo spoke matter-of-factly, not understanding Itachi's true meaning.
"Ahem, you see, I used a lot of my Mangekyō ocular power in its creation, and now if I just seal it..."
Hearing this, Hagoromo stared at Itachi silently for three straight minutes before finally sighing.
"I will help you awaken the Rinnegan. But you will have to promise me that you will never use souls or magical power ever again."
Hearing this, Itachi smiled in satisfaction. As expected of a thousand-year-old man, he was indeed generous. Perhaps, for Hagoromo, this was a favor to win him over, or maybe he had other intentions, but regardless, Itachi had gained an advantage.
"Then, you have a dea—"

Outside World
"Yo...u wi...ll pa—"
Hiruzen took his last breath in pain and confusion. Pain because, in the end, he died from blood loss, and confusion because for the past few minutes, Itachi had remained frozen midair with a purple-black ominous spear in his hand.
Just as Hiruzen took his last breath, Itachi suddenly opened his eyes. Looking at the spear in his hands, his expression slightly changed.
Thick black clouds gathered and descended onto the ground, making it appear as though Konoha had been transported into a sea of clouds high in the sky. The next moment, Konoha was reduced to complete darkness.
The few remaining civilians and ninjas still alive inside shelters and bunkers, witnessing what looked like the end of the world, couldn't help but stare at the only purplish source of light.
Itachi, on the other hand, absorbed all the souls still remaining within dozens of nearby kilometers.
"Still not enough."
Itachi murmured while looking downward at the hundreds of thousands of people still alive and nodded in satisfaction.
"You shall be the perfect sacrifice for it."
The next moment, he pointed the spear toward the ruins of Konoha.
"This weapon shall be known as...
The Spear of Singularity: Sagittarius."

On the other side, Fugaku and the others had also noticed the strangeness of Itachi's pause and the sudden change in his aura. Although they couldn't see chakra nature like members of the Uzumaki clan, they could still sense the difference with their Mangekyō Sharingan.
"Uncle, I can feel that Big Brother Itachi's current aura resembles that spear in his hands," Naruto, who had partially awakened the Kagura Mind's Eye, said with concern.
"Hmm, Obito, take Sasuke and Naruto to your Kamui dimen—"
Fugaku, who was giving instructions, suddenly paused after hearing Itachi's words.
"Father, Haruto previously said that Big Brother wouldn't want Sagittarius to fall. Earlier, nobody knew what it was, but now it seems to be the weapon he just created. We should stop him."
"Okay, Obito, take care of the two of them and come reinforce us immediately after that." After saying this, Fugaku rushed toward Itachi alongside Shisui.
"Tsk, I knew that descendant of Indra would be unreliable in matters like this. Looks like I have to empty my pockets tod— hmm? Well, it seems the trouble is gone."
"ITACHI, STOP!!! REMEMBER HARUTO'S WORDS!"
Shisui, standing atop Nanabi, who had just been summoned for quick transport and flight, shouted at Itachi in a hurry.
"Shisui, leave me alone."
"No, you are being affected by that weapon. Maybe Mōryō left behind a trap. We must go to the Land of Demons and meet the Priestess right now!" Fugaku said sternly.
Hearing this, Itachi paused for a moment but ultimately shook his head.
"I am doing this for the safety of the Uchiha clan. Anyway, it doesn't matter whether I kill three hundred thousand or seven hundred thousand people. If Sagittarius is completed, then we won't have to worry about the Uchiha clan's safety anymore, and it will continue protecting the clan even after my death. Leave."
Hearing this, Fugaku and Shisui became conflicted. After the past year, they no longer cared about Konoha, so Itachi's words sounded reasonable to them.
However, their instincts, along with Haruto's warning, made them hesitate. If Itachi was left alone, something truly terrible might happen.
"It doesn't matter. I will protect you within a barrier. Just sit back and watch the show."
As he spoke, Itachi completely ignored the approaching Obito. With a snap of his fingers, he trapped Shisui and Fugaku inside a transparent barrier created through his Domain Expansion. Then, pulling his arm back, he prepared to throw the spear.
"Uncle Itachi, waiitttt!!!!! CELEBI, it's your turn!"
Just then, a childish voice rang out through the sky as a child and a strange creature descended from the black clouds above.
"Harutooo!!! It's dangerous!"
Seeing his own child caught up in the situation, Obito immediately stopped slacking off and rushed toward Haruto.
"CEELLLEEEBIIIII!!!!"
At that moment, Celebi's cry echoed across dozens of surrounding kilometers. A brilliant green light burst forth from its body, with Celebi at the center, spreading in every direction until the entire world seemed bathed in a radiant green glow.
Inside the light, Itachi's emotionless expression suddenly shifted to confusion, then helplessness.

"It looks like you are back."
Hearing the Sage of Six Paths' slightly sarcastic remark, Itachi looked down at his feet in embarrassment.
Well... he had just been controlled by his own creation. More accurately, Sagittarius was currently connected to his Mangekyō Sharingan, and therefore to himself. When it sensed the possibility of his demise, it reacted instinctively and influenced him to complete the unfinished process.
While talking with the Sage of Six Paths, Itachi had been distracted, and Sagittarius used that perfect opportunity to take control of him through the power of the hundreds of thousands of souls it had recently devoured.
As for why it awakened consciousness so quickly instead of taking time like ordinary gods, as Hagoromo had explained, it was because his Domain Expansion was at the Transcendent level. The fusion had been perfect, eliminating the need for time to digest and allowing a nascent consciousness to form immediately. However, to develop full sentience, it would likely require more souls or more time.
"Well, the difficulty of sealing it might have increased by a few levels."
Sigh
