After all, they're already dead. Even if their current bodies turn to dust, they will just return to the Pure Lands to be reborn one day. Besides, they will have time to convey the message to Konoha: there is not a drop of the Will of Fire in Uchiha Yue's heart.
The only irreparable loss will be Sasuke. The last sprout left by Itachi will be uprooted. However, this is a small price to pay, because from the very beginning they did not expect Sasuke to survive. Only Itachi continued to cling to his blind faith.
He believed that Sasuke would be able to get out alive. It was his last hope. What else could he do but believe?
Their hearts were filled with despair, but not anxiety. Or so it seemed to them up to this point.
Sarutobi Hiruzen's legs crumbled with a crash, and he slowly sank to the ground. His body, like a sand sculpture, began to crumble and disintegrate, exposing the hidden essence inside.
"Damn Uchiha Yue... looks like I'm going to have to die again!"
The bodies of Shimura Danzo and Uchiha Itachi also crumbled to dust. The last shreds of their chakra were absorbed by Yue.
They were already preparing for another return to the world of the dead, however…
"What's going on?"
Sarutobi Hiruzen's face twisted in horror. When his resurrected body finally crumbled, his soul was released. But as soon as she appeared, she immediately began to fade rapidly.
Now, looking at the world from the point of view of the soul, he saw how the veil of mystery had fallen from the dark, starless space. But Hiruzen would rather never see this and just return to the Pure Lands.
He made out three blurry, glowing silhouettes hovering nearby—the souls of Shimura Danzo, Uchiha Itachi and Uchiha Sasuke.
"These are... our souls."… How is this possible? Does the soul stay here after death? Why didn't I feel anything like that last time... no, that's not it… Why do I feel like I'm getting weaker?
Hiruzen looked at himself. His ghostly form became transparent before my eyes. His soul was being consumed.
— no! No, I don't want to die! Let me go! Mr. Uchiha Yue, I beg you, let go! Don't devour my soul!
Shimura Danzo's soul was rushing madly in the void. He understood everything. He was really dying, irrevocably. His very existence was erased. Sensing this, Danzo panicked and began desperately begging for mercy.
The death of the body could be reversed with the help of Edo Tensei, gaining an immortal shell. Back in Konoha, he contacted his former henchmen and was going to resurrect after this case to become the eternal, invulnerable Darkness of Konoha. But now... it's over. It's over!
— Sasuke… No, it's not.…
Uchiha Itachi, looking at Sasuke's rapidly melting soul, let out a mad scream. He jerked, trying to reach his brother, grab him.
But it was too late.
Sasuke's soul burst like a soap bubble. He's the one who ruined him. He's on his own. If it wasn't for his actions, none of this would have happened.
The Uchiha clan would not have been exterminated, Uchiha Yue would not have gained his power, the respected Third Hokage would not have died, and his beloved younger brother would not have been erased from the universe.
Regret. That's the real regret. If earlier he was tormented only by the fact that he raised his hand against innocent clansmen or that he did not kill Yue with one blow, now he regretted everything. You shouldn't have attacked the Uchiha clan.
If he hadn't done that, nothing would have happened. In the end, his so—called protection of the village, the so-called protection of Sasuke, all turned out to be lies. He didn't protect anything. He's a sinner.
— The end… This is the complete end…
Sarutobi Hiruzen was just as desperate. He had never imagined that Yue had reached such a level of power that he could destroy souls themselves.
Yes, they never thought about it, they never even imagined it. After all, knowledge about the soul in the Shinobi world was extremely superficial. They knew of her existence, but they had no idea how to counter her. It never even occurred to them that the soul could be destroyed.
Everything happened too fast. When they found out about the Sage of the White Snake, their plan was almost ready, all they needed was a powerful enough chakra. They were about to use the power of the Nine-Tails, but then the toads from Mount Myoboku brought them Senjutsu, allowing them to put together the last piece of the puzzle.
And they really succeeded. They were able to keep Edo Tensei's body and even Sasuke's life at a minimum. They saw Yue and talked to him. If they had convinced him, the plan would have been perfect. Hiruzen and the others would never have known that their opponent was capable of devouring souls.
Unfortunately…
"No, I'm not."… That won't do! I have to survive! I have to!
At that moment, Sarutobi Hiruzen began to struggle desperately. He felt an attraction from an unknown dimension. All he had to do was hold on, a little longer, and he could go in there and continue living.
He must bring the news to Konoha! I have to let Tsunade and the others know that they have not failed — there is simply no Will of Fire in Yue, he is pure, absolute evil.
Hiruzen knew that if he died now, the village would think that their attempt at persuasion had failed. Or, more likely, they will decide that they just ran out of chakra and disappeared without reaching their destination. Even when Konoha discovers that they cannot resurrect them, when they realize that the Yue space absorbs souls, they will not give up their stupid idea. On the contrary, blinded by greed, they will rush with renewed vigor in search of a meeting with him.
This will eventually lead to Konoha's demise. Yue's existence is like a carrot suspended in front of a donkey's nose. She's so close that it seems worth taking a step and she's yours. But the donkey is destined to die of exhaustion before reaching the goal.
To survive.
