Chapter 194: Susanoo Army

More than 20,000 shinobi collapsed instantly after being hit by the wave of Conqueror's Haki. It wasn't just the invaders who suffered, some civilians and unprepared ninja within Uzushiogakure also fainted under the pressure.

Setsuna had not yet mastered Conqueror Haki to the point where he could selectively target enemies while sparing allies. That was why he had instructed everyone to stay back. If anyone stood too close on the front lines, they would collapse just like the invaders.

"This… what is this?" Raikage muttered in disbelief, his body are also trembling in fear.

They had not yet seen the face of the one who dared challenge them. All they heard was a voice, a very calm voice yet thunderous warning and the next moment, a crushing pressure descended on them all. It was as if the air had turned to stone, and every breath came with pain. None of them could identify the source of this invisible force.

Setsuna didn't speak again. He simply Kamui'd himself back behind the barrier, reappearing amidst his own forces with an unreadable expression.

He looked at Uchiha Team and it looks like the Conqueror Haki didn't do any damage to them.

"Everyone with Mangekyō Sharingan, get ready it is time to show the power of Uchiha," he ordered coldly.

"We are ready" said them with unison.

He then activated one of his secret abilities from the system, Special Clones. Unlike typical shadow clones, these ones possessed the same chakra level as the original and could not be dispelled by ordinary damage. Even if they were impaled, crushed, or burned, the clones would persist. The only way to remove them was for Setsuna to cancel the technique himself, or for the time limit to expire.

He created nineteen of them, each with his full strength and assigned one clone to every group of Uchiha present and kamui'd them to the front of an enemy . Some clones will form trio group and some will form duo group. In perfect coordination, the clones and the Uchiha warriors launched forward together, heading straight toward the main forces of the enemy.

The ground trembled under the synchronized charge. Thirty-six Mangekyō Sharingan activated in unison, their crimson glow cutting through the fog like cursed lanterns. One by one, giant skeletal figures began to rise around them. Susanoo.

From the sky, it looked like titans had awoken and were marching toward battle.

The time for war had begun.

---Enemy---

"What is the status of our shinobi?" asked the Raikage once he managed to stabilize himself, though his breath was still heavy and his fists clenched.

The jōnin beside him had a hard time to reply the question from Raikage. It took him a while before he nodded and closed his eyes, focusing his chakra to send a pulse through the battlefield, a coded signal only allied units could respond to. A minute later, he opened his eyes, visibly shaken by the report streaming back to him.

"Raikage-sama… more than one-sixth of our forces have fainted," he said with a grim face. "Some are unconscious, and… there are confirmed cases of shinobi losing control of their bladders and peed pants because of fear."

The Raikage's eyes narrowed. Over 10,000 shinobi—gone from the field in mere seconds. Even if they were low-ranking genin or less experienced fighters, the sheer number was alarming. Worse, many others were still conscious but frozen with terror, unable to lift a kunai or form a seal.

He wasn't the only one feeling the weight. Across the battlefield, the other Kage were experiencing the same oppressive atmosphere. No one had seen the attacker clearly, only heard his voice, calm yet very intimidating and then the crushing wave that followed. It wasn't chakra, not in any known form. It felt older, stronger… primal.

"Did they use a pressure-based sealing jutsu?" the Raikage finally asked, trying to rationalize what had just happened.

"We don't know for certain," the jōnin replied, wiping sweat from his brow. "But there's a strong possibility. The Uzumaki Clan has long been known as the masters of fuinjutsu. It might be a wide-range suppression seal hidden in the terrain."

The Raikage looked toward the direction of the barrier, his sharp gaze narrowing on the motionless landscape behind the barrier. "Or... it could be something else. Something we've never seen before."

A heavy silence fell over the group. The morale had taken a sharp dive, and fear began to fester even among the elites.

Suddenly, just a few minutes later, the space around each invading group began to swirl—and from within the distortion stepped Uchiha Setsuna and his Uchiha Team.

Without hesitation, the Raikage lunged forward, attacking the moment their faces appeared. The other shinobi followed suit, gripping their kunai and launching themselves at the intruders. It wasn't just the Raikage; the Tsuchikage, Kazekage, and Mizukage also reacted immediately, unleashing their own techniques.

On the side of the Iwagakure forces, the Tsuchikage's Dust Release shot toward Setsuna's group. But to their horror, it had no effect whatsoever, Setsuna and his allies remained standing, completely unharmed.

"So you're the ones who wanted to destroy this land," Setsuna said calmly, his eyes glinting with silent fury.

"Who are you?" the Tsuchikage demanded, his voice filled with suspicion.

"I am Uchiha Setsuna," Setsuna replied.

That name alone caused sweat to form on the Tsuchikage's forehead.

He vividly remembered being defeated by Uchiha Madara in the past. And now, standing before him was another Uchiha who bore the same overwhelming pressure, perhaps worse. The legend of Uchiha Setsuna was already being spoken of in the same breath as Madara, but what unsettled the Tsuchikage the most was Setsuna's appearance, he still looked young, far too young.

"You… how are you still young?" the Tsuchikage asked in disbelief. Then his eyes widened. "Wait..... your voice. You're the one who warned us earlier!"

---Susanoo Army---

Their earlier attacks had failed, completely. Not a single scratch had landed on Setsuna or his comrades.

"Guys, activate your eyes," Setsuna ordered calmly.

Immediately, everyone who heard him activated their Mangekyō Sharingan. Chakra surged into the air, forming spectral armor around each of them.

A Mangekyou Sharingan ultimate power is Susanoo, and each Susanoo colors are different. The Susanoo began to fill the battlefield, white, pink, red, blue, purple, black, yellow, and green, each towering like a colossal warrior of legend.

Even from afar, the invading ninja were forced to halt, staring in stunned silence at the army of chakra titans marching forward. The sight alone was enough to break morale. For the first time, they understood, they had already lost this war.

"What kind of monsters are we up against?" the jōnin whispered again, as the earth beneath them trembled under the march of the Susanoo army.
