Yumeko used the Mayfly Technique, completely blending her figure into the surrounding dust and shadows. Her speed was so fast and her presence so well concealed that it had almost reached a level ordinary people could hardly imagine.
Uchiha Katsu's Sharingan was fully activated, the Mangekyo spinning rapidly, yet he still could not catch the slightest trace of his opponent.
His perception was completely cut off, leaving only an empty road in his field of vision.
"What an incredible concealment technique. Even more terrifying than White Zetsu's..."
Uchiha Katsu's brows knitted tightly as he felt that this was truly troublesome.
This person's concealment technique was far beyond his expectations.
In this brief moment of emptiness, Uchiha Katsu's eyes suddenly sharpened.
"Sage Mode, activate!"
The next moment, Uchiha Katsu directly activated senjutsu.
The natural energy of Mount Myoboku instantly surged into his body, and the range of his perception spread at a terrifying speed.
The aura that had completely disappeared was once again locked onto with the help of senjutsu.
"Found you."
Uchiha Katsu muttered, his figure shooting forward like an arrow as he chased after her.
Not far ahead, Yumeko revealed a smile.
"Hehe, you want to catch this young lady? Black Zetsu's Mayfly Technique is really useful..."
All these years, as she wandered through the shinobi world, whenever she wanted to run, no one except the Observer could catch her.
"Haha... uh..."
Yumeko had only been smiling for a few seconds when she suddenly sensed that strong, familiar yet extremely out-of-place aura behind her.
Yumeko's smile instantly froze.
She abruptly turned her head, and her expression changed at once.
"Indra... how does he know Mount Myoboku's senjutsu?!", She muttered to herself in disbelief, her voice full of shock.
The person in front of her could actually use Mount Myoboku's senjutsu?
"How is this possible?!"
A huge sense of disbelief surged through Yumeko's heart.
She clearly remembered that in the original work, no Uchiha who could use senjutsu had ever appeared.
If such an existence had really existed, he definitely would have left a major mark in the original work.
Yet now, this Uchiha who should have merely been Indra's reincarnation had genuinely used Mount Myoboku's senjutsu and was accurately chasing after her.
The night wind howled as the distance between the two rapidly shortened.
"It's bad. This guy is getting faster and faster!"
Yumeko's expression turned completely serious.
She no longer had any intention of testing him and directly pushed the Mayfly Technique to its limit.
Her figure almost completely became invisible, and her speed surged once again as she tried to completely shake off the person chasing her.
However...
Uchiha Katsu's eyes suddenly turned sharp.
He was more familiar than anyone with that concealed aura.
The Mayfly Technique... originated from Black Zetsu.
"He can even use Black Zetsu's. No wonder he's so fast and so good at it...", Uchiha Katsu snorted coldly.
He had already detected Black Zetsu's existence earlier, so he had long since gained experience dealing with this almost perfect concealment technique.
With senjutsu perception combined with the Sharingan, he instantly and accurately locked onto Yumeko's true position.
The next moment, he quickly closed in.
"Don't come over!!"
Yumeko was startled and had no time to think.
Her chakra compressed violently, and a Rasengan instantly took shape in her palm. The rotating wind blades gave off a piercing hum as they carried destructive power and directly blasted toward Uchiha Katsu!
"Wind Release: Rasenshuriken!!"
Uchiha Katsu's pupils suddenly contracted, and his expression immediately darkened.
'Rasengan?!'!
This ninjutsu should have appeared in the distant future, yet at this moment, it had been used ahead of time by the woman in front of him.
A huge wave of shock surged through Uchiha Katsu's heart, but his body did not hesitate in the slightest.
Relying on taijutsu far beyond that of ordinary people and the Sharingan's prediction, Uchiha Katsu turned sideways to avoid the direct impact of the Rasenshuriken while closing in at the same time.
Yumeko continuously used all kinds of ninjutsu she had learned over the years. Fire Release, Wind Release, and even several obscure sealing techniques were thrown out one after another as she tried to create distance.
But in front of Uchiha Katsu, all of this seemed pale and powerless.
Every one of his evasions was precise to the limit, while his counterattacks were swift and fierce.
In just a few exchanges, Yumeko's attacks were completely suppressed.
The instant Uchiha Katsu caught an opening, he precisely struck the back of Yumeko's neck with the edge of his hand.
Her vision suddenly went black, and her body completely lost its strength, collapsing limply onto the cold ground.
Without giving her any chance to catch her breath, Uchiha Katsu rapidly formed hand seals. Several specially made chains and black curse marks shot out at the same time, tightly wrapping around Yumeko's limbs and torso and completely restraining her on the ground.
Her chakra was forcibly sealed, leaving her unable to put up even the most basic resistance.
Uchiha Katsu looked down at her, and a long blade suddenly appeared in his hand.
A cold glint flashed across the blade as it was placed directly against Yumeko's neck.
The cold blade pressed tightly against her skin. With just a little force, he could completely end the life of the woman in front of him.
"Who are you, exactly?"
Uchiha Katsu's voice was low, carrying suppressed killing intent. "Why do you know these things? If you don't tell me, I'll kill you."
A trace of blood spilled from the corner of Yumeko's mouth, yet she suddenly laughed coldly.
She raised her eyes and looked directly at Uchiha Katsu above her, her voice hoarse yet exceptionally calm. "I'm afraid... you don't dare kill me."
After saying that, her thoughts raced.
The Observer must be watching her.
To prevent the plot from completely collapsing, he would definitely find a way to keep her alive.
Thinking of this, the fear in Yumeko's eyes completely disappeared, replaced by a calmness that was almost certain.
Even her breathing became much steadier.
"Haha?!"
After hearing this, Uchiha Katsu suddenly let out a low laugh.
The blade remained firmly pressed against Yumeko's neck. He looked down at her, his voice carrying a hint of mockery. "You think... someone will come save you now?"
Yumeko's eyes flickered slightly, and she answered directly, "The Observer. He'll make a move."
Uchiha Katsu's brows lifted slightly.
'The Observer?'
He instantly decided that the woman in front of him was probably crazy.
Driven into a desperate situation, she had started making up some inexplicable existence to scare him.
How ridiculous.
He did not attack immediately. Instead, he continued questioning her, his voice cold. "If he really exists, what are you to him? Why would he care about you?"
Yumeko's expression tightened slightly.
What should she say?
She couldn't exactly tell him it was because of the system binding, could she?
Her eyes quickly turned as her mind rapidly came up with a reason. Then she raised her chin and said firmly, "I... I'm actually his daughter!"
Upon hearing this, Uchiha Katsu slightly raised his brows, and the amusement in his eyes grew even stronger.
"Nonsense."
"Let me tell you the truth. You have someone behind you, and I have someone behind me too. And the person behind me is an existence you can't afford to provoke.", Uchiha Katsu said calmly.
As he said this, that person's figure naturally surfaced in Uchiha Katsu's mind.
'Lord Arisu.'
That existence hidden behind the scenes, controlling everything.
Lord Arisu was the true will of heaven in this shinobi world.
The blade pressed down slightly, and its cold touch became even clearer against Yumeko's skin.
"Since that's the case, then I'll see whether your Observer father will save you..."
Uchiha Katsu's killing intent erupted.
Yumeko panicked and hurriedly shouted toward the sky, "Mr. Observer!!! Save me!!!!"
