Simultaneous traversal: All Abyss difficulty.

Chapter 378 (Third Update) Sasuke in Boruto's Storyline
The moment the milky-white giant sword cleaved down, the purple Susanoo suddenly spread its wings!

The middle-aged Sasuke rapidly retreated, manipulating his Susanoo, while his pupils shone with intense purple light!

"Amaterasu Kagutsuchi!"

Black flames spread upwards along the chakra giant sword, instantly enveloping Uchiha U's Susanoo!
Uchiha Ushun broke free from the Susanoo's encirclement, deactivated the Susanoo, and the eye shadow of Sage Mode appeared. He suddenly clasped his hands together and shouted, "Sage Art: Crimson Water Dragon!"

Towering waves surged from the crack, transforming into a crimson water dragon entwined with natural energy!
The dragon head roared to the sky and pounced on the purple Susanoo!
"Fire Release: Great Fireball Technique!" The middle-aged Sasuke quickly formed hand seals and unleashed a blazing fireball tens of meters in diameter from his Susanoo protection.

The moment water and fire collided, a steam explosion obscured the entire battlefield!
It's now
A fierce shout came from the steam: "Planetary Devastation!"

The gravitational core of the Rinnegan suddenly appeared high in the sky, and countless pieces of rubble and soil were forcibly stripped from the ground and frantically converged towards the gravitational core in mid-air!
Even the remains of the Crimson Water Dragon were torn into water droplets and sucked into it!
"ended."

Middle-aged Sasuke, panting, stared intently at the gradually forming meteorite sphere.

However, the next second, his Rinnegan suddenly contracted!
Uchiha Yu's figure appeared out of thin air behind him!

"Flying Thunder God."

"Pfft!"

A kunai pierced through middle-aged Sasuke's right shoulder, and blood splattered onto the Kusanagi sword.

Sasuke stumbled forward, turning back in disbelief: "Impossible! This is the Second Hokage's technique! What are you doing?"

Uchiha U's eyes, however, did not look at Sasuke's face, but stared at the other side.

With a "bang," Sasuke, who had been stabbed, disappeared! His real body appeared next to Boruto on the other side.

Sasuke quickly told Boruto, "Something's fishy. Find a direction and run, preferably towards Konoha. Don't linger in the fight."

“Hey, there’s no need to arrange it like this.” Uchiha Yu interrupted Sasuke’s mutterings. “You’re talking like someone’s going to kill him. I’m not that perverted brother of yours.”

Sasuke suddenly paused, staring at Uchiha U with wide eyes, not daring to respond.

"Stop pretending, what is gay?"

Boruto, middle-aged Sasuke, and young Sasuke all had their pupils shrink slightly!
Even Jiraiya looked on incredulously.

"What! How could this be! You're saying this guy is Sasuke?" Naruto exclaimed, realizing what was happening.

Young Sasuke was so shocked that he felt as if he had been under a genjutsu!

Even Sasuke, with his exceptionally high IQ, found such nonsense unbelievable.

Just then, people finally arrived from the direction of the Sound Village!
"Boohoo!"

Sakon, Jirobo, Tayuya, Kidomaru, Kimimaro! The Sound Five report!

"Hey, how dare you cause trouble in the Sound Village!" Kidomaru shouted at the middle-aged Sasuke, hands on his hips. "Then leave your lives behind!"

Seeing that the Sound Five were ignoring Jiraiya, Naruto, and his younger self, the middle-aged Sasuke increasingly felt that this was a fictional world similar to the Infinite Tsukuyomi.
How could Jiraiya possibly be standing with Orochimaru's subordinates?
Thinking of this, middle-aged Sasuke suddenly looked towards the woods on the other side!

"So fast!"

No sooner had he finished speaking than three figures appeared!
These are, respectively, Tobirama Senju (Edo Tensei), Orochimaru, and...
The Fifth Hokage, Tsunade?

how can that be!

It's fine as long as the three ninjas are on good terms!
How could the Second Hokage possibly be with Orochimaru!
Before Sasuke could react, Tobirama Senju roared, "You born evil Uchiha brat, I'll finish you off!"

Before Tobirama Senju could even complete his Water Release technique, a giant Buddha's hand split the battlefield in the center!
Tobirama Senju looked up at the thousand-meter-tall Buddha statue and sighed helplessly, "What did my brother even teach me! Sigh!"

Boruto was completely dumbfounded when he saw the jutsu's exaggerated range! "W-w-w-w-w!"

Meanwhile, the middle-aged Sasuke on the side had his eyes fixed on Uchiha Yu, who was standing on the Buddha statue!
This aura instantly reminded Sasuke of the feeling he had when facing Madara Uchiha during the Fourth Shinobi World War!

With a calm gaze, Uchiha U spoke to the middle-aged Sasuke.

"Let's talk."

"Or we'll fight." "You choose."

Sasuke was silent for a moment before nodding. "I also have something I want to ask you."

Sound Village.

Sasuke (both the older and younger versions), Boruto, Naruto, and Uchiha Yu walked down the street.

When middle-aged Sasuke saw the Uchiha clan members from his memories building houses, he was completely stunned! He was even more shocked than when he saw the Great Buddha with thousands of arms!

"This! How could this be!" Boruto had some knowledge of history, and he knew clearly that there were only two Uchiha clan members still alive in the entire ninja world.

A mentor to Sasuke.

One Sarada.

Why is this village full of Uchiha?
The Uchiha clan members initially greeted the strangers who entered the village with friendly expressions.

But when they saw that there was a former young master in the crowd, the faces of these people immediately fell!
Seeing this, the middle-aged Sasuke glanced down at his younger self, his expression hesitant, but still said, "It's not your fault."

"Hehehe," Sasuke chuckled coldly without even looking up, "Of course you have to blame me for having such a beastly brother!"

"You!" The middle-aged Sasuke never imagined that his younger self would say such a thing about Itachi.

But thinking about it, it makes sense. Didn't I want Itachi to die back then?
It's only right to scold him a couple of times.

However, what happened next was that middle-aged Sasuke's worldview was shattered once again!
"Clan leader!"

A group of Uchiha gathered around, and the elder in the lead said, "The disease among us has begun to spread. If we don't drink Lord Orochimaru's coffee for a day, then..."

"Increase the dosage." Uchiha Yu waved his hand, and everyone nodded and left.

"You? The Uchiha clan leader?"

Even the usually composed middle-aged Sasuke couldn't hold back at this moment; he couldn't accept that a guy who looked only eleven or twelve years old had become the head of the Uchiha clan.

Even though Uchiha U's strength was extraordinary.

Sasuke couldn't reconcile his father's image with that of Uchiha U.

For the Uchiha clan to have such a clan leader is truly a blessing in this lifetime.
"Of course I am the clan leader. If I am not the clan leader, then who is Fugaku?"

Upon hearing Uchiha address him by his name, Sasuke frowned. "What exactly happened?"

“It’s very simple,” Uchiha Yu said casually. “On the night of the massacre, I repelled Obito and Itachi, and killed Danzo.”

This casual remark caused the middle-aged Sasuke, who was walking, to abruptly stop and stare at Uchiha U with a look of astonishment.

He clutched his throbbing forehead. "I... I can confirm that I'm not in the Infinite Tsukuyomi. What... what is going on?"

Uchiha Yu sighed softly, "Rather than knowing the answer, I'd rather make a contribution."

He took two steps forward and then turned back. "Our world is on the verge of collapse. Jigen has started the war ahead of schedule. Let's do something, Sasuke."

"Wait a minute!" Boruto suddenly interrupted Yu, "Master said we shouldn't interfere with things that have happened in the past, because that would change the future!"

Uchiha Yu crossed his arms and said, "The reason your future is in danger is because I'm not here!"

"Wait! Wait a minute!" Naruto interrupted Uchiha U, belatedly pointing at Boruto: "If he's Sasuke, then who is this guy?"

Boruto scratched the back of his head. "You, your son."

"Oh," Naruto nodded and took a few steps forward.

Suddenly! Naruto stopped in his tracks and whirled around! His voice echoed throughout the Hidden Sound Village, "N-Nani!?"
