After sending the precious explorers to safety, Ootsutsuki Isshiki detonated the Dragon Vein, which had long been turned into a bomb, without the slightest hesitation.
There was a deafening roar, and at that moment the entire continent of the Shinobi world shook. A monstrous mushroom explosion that propped up the heavens and pierced through the atmosphere was slowly rising. This event was so large-scale that it seemed to announce to the whole world that trouble had struck!
— It's not good! — it was heard in the Pure Lands.
Feeling the terrifying wave of energy that swept through the Shinobi world, the three Sages of the Six Paths immediately turned their gaze to where the Dragon Vein was located.
Looking at the growing nuclear mushroom, they fell into silence. The sages understood perfectly well the significance of the Dragon Vein for the current Shinobi world, which means they were aware of the consequences of its explosion.
"He's…
"He's here!"
Those who arrived from a parallel world, terrified of Uchiha Yue, stared at the mushroom cloud in a daze. They were trembling, and they couldn't help but whisper:
"No... it can't be!" Why? We've already come to this world!
"We've already left two worlds, but... why?" Why can't we get rid of it yet?
— This shouldn't have happened, it shouldn't! It's already the third world!
— Oh gods, I pray, show your might, save this world!
"It's over, it's over... the dragon vein is destroyed...Mother, what should I do now?!"
— no!!! No!!!
—Damn Uchiha Yue, you bastard! We've already escaped from your world, so why, why are you…
After the explosion of the Dragon Vein, the entire Shinobi world was plunged into lamentation and despair. Now everyone understood what this explosion meant: the world was over, Uchiha Yue had appeared!
And they never managed to find a new world.
"So what do we do now?"
— …
In the teleportation array, Tobirama's two Senju stared dumbfounded at the huge mushroom cloud covering the sky. Confusion gripped their hearts.
— Create an imitation of a Dragon Vein! Keep on, keep on looking for a new world! Don't give up, I'm the other one! We will definitely be able to leave this world! Tobirama was encouraging his doppelgangers from this world.
They had previously considered what to do if the Dragon Vein was blown up.
You can stop Uchiha Yue for a while, but then what?
To hold it for a moment does not mean to stop it forever. The only way out is to escape. So the plan to create an imitation of a Dragon Vein was born. After scanning its energy composition and structure, they developed a method that allows them to recreate a new Dragon Vein using a huge amount of energy.
However, this method has so far existed only in theory and has never been tested in practice.
On the moon.
"What happened?"
The Shinobi world was shaken by an incredibly powerful wave of energy. Ootsutsuki Toneri stopped what he was doing and listened attentively to the sensations, just shook his head and returned to his business.
In Konoha, Uchiha Izumichi felt the ground tremble under his feet.
—Wh-what... what's going on?" He muttered as he looked at the explosion mushroom slowly growing in the distance.
"Really... big brother?" Is that how he's going to deal with it?
When he saw this picture, he instantly realized that Uchiha Yue, whom everyone was talking about, had begun to act in their world.
Being a hitman, he still believed that all these Shinobi were just going crazy. He believed that Uchiha Yue had destroyed his world and stopped there. If he had any kind of time travel system, he had long since disappeared. All these fears seemed to him to be empty worries.
He was more worried about Ootsutsuki Isshiki. Although the threat of the Sharingan seemed to deter him from attacking the Shinobi world, but who knows what might have happened?
He could not have imagined that while Ootsutsuki Isshiki had not yet begun to act, Uchiha Yue, whom he least took seriously, would do it.
— Oh!
In the main world, Uchiha Yue watched as the space in front of him was plunged into darkness and distorted. A smile played on his lips.
So they blew up a vein to disrupt the space? Funny, but pointless.
He immediately began to probe the space, intending to reconnect and envelop that world in eternal darkness.
In a second parallel world.
After the explosion of the Dragon Vein, the distortion of space stopped. It seemed as if nothing had happened, except for the void gaping in place of the vein.
All efforts were devoted to creating a new Dragon Vein in the hope that it would work.
At the same time, the entire Shinobi world was mobilized for the insane construction of spaceships. If the Dragon Vein turns out to be useless, all that remains is to escape from this planet.
The atmosphere became oppressive, tense to the limit. The spirit of the coming battle was everywhere.
There were two people sitting in Ootsutsuki Isshiki's estate—he and his doppelganger. They were silent.
Sticky terror was spreading in their hearts. They didn't expect Uchiha Yue's arrival to happen so soon. They have not yet found a new parallel world, and this monster has already overtaken them, completely destroying all plans.
There was less and less time left!
The thought of escaping from this planet burned in their minds like wildfire.
But there was only one Child from the prophecy!
To be reborn, one of them will have to kill the other, take the Child from the prophecy, resurrect, and then leave this planet forever.
However, their strengths were roughly equal. The result of the battle could be not the defeat of one, but the death of both.
For Ootsutsuki Isshiki, even his doppelganger from a parallel world became an enemy that should be destroyed at the slightest threat to his own survival.
After a long time.
"We shouldn't do this. There's still time, we still have time! — said one. — The other me, as soon as we create a new Dragon Vein and, like last time, find a new world, we will have hope!
— The other me, it's you... it's all your fault! — the second one answered.
"It's you!" If you hadn't come to my world, how would Uchiha Yue have known about its existence?
"No, you're wrong. My appearance, on the contrary, saved you. You have to understand: if it weren't for me, the Uchiha clan massacre would have already happened, and a new Uchiha Yue, a new living disaster, would have been born in your world. And then you, like us in that world, full of boundless self-confidence, would have quietly and imperceptibly died by his hand!
Both Isshiki argued, but eventually gave up on the idea of fighting. The battle could wait, because there was still hope for them now.
This fragile peace lasted for five days. On the fifth day, they violently attacked each other.
The sky... darkened.
