Inside the cave, a pair of eyes gradually filled with bloodshot veins, staring intently at the outside.

Whoosh!

A flurry of cold gleams flashed by, with sharp kunai embedding directly into the surrounding hard rock.

However, the strange figure saw that the first to enter was neither a man nor a woman, but a pile of kunai, also tied with hissing detonating tags. His pupils instantly constricted.

“Roar! None of them! Haha, then let’s charge out and kill them all!”

Boom!

In the next moment, a terrifying explosion echoed through the cave, coinciding with the thunder above.

“They’re coming out!”

With a loud crash, as a shadow appeared, Uchiha Mikoto shouted a warning.

However, upon seeing the figure charging out of the cave, Uchiha Yoru immediately displayed a look of realization.

Just as expected! Mikoto’s information was exactly as he thought.

“Haha!”

The monstrous shadow that rushed out laughed maniacally, its face displaying terrifying black markings that were visibly spreading, continuously evolving into a monster.

This was not a tattoo!

This was a cursed seal!

“Zhongwu! Cursed seal! Naturally born sage body!”

Upon seeing the figure, Uchiha Yoru revealed a hint of surprise, while Uchiha Mikoto beside him exclaimed, “Yoru, you know?”

At this moment, seeing this monster, especially with the black markings continuing to spread, Uchiha Yoru coldly shouted:

“I’ve heard similar rumors. Let’s finish this quickly; don’t give the opponent time to evolve the cursed seal.”

Without any hesitation, the two of them instinctively jumped to two large trees.

The monster that rushed out of the cave began to laugh maniacally and bloodthirstily upon spotting its target.

“Haha, blood! I want your blood!”

The crazed monster charged directly at Uchiha Mikoto, while Uchiha Yoru quickly formed hand seals on the other side.

“Kill!”

Sizzle…

In the next moment, a harsh sound rang out, accompanied by the snapping of steel wires. It turned out that the monster had fallen right into the pre-set wire trap.

However, under the enhancement of the cursed seal, the monster roared frantically, breaking the hard, sharp steel wires one by one.

At that moment!

Fire Release: Great Fireball Technique!

Uchiha Yoru gathered chakra at his throat and suddenly spat out a massive fireball, aimed directly at the monster’s back.

“Yoru!”

Seeing this scene, Uchiha Mikoto also shouted, quickly forming hand seals, then spat out a fireball even larger than Uchiha Yoru's.

Fire Release: Great Fireball Technique!

Two enormous fireballs, one after the other, surged toward the monster, leaving it no chance to dodge at such close range.

Moreover, this frenzied monster had no intention of dodging; it roared and charged toward the massive fireball.

Brute force!

Boom!

The fireball exploded under the rain, the crashing thunder echoing and drowning out the sounds of battle.

Boom!

The explosions of detonating tags and ninjutsu reverberated throughout the forest, and the monster that lay in the wreckage was no longer human.

“Damn it! This monster has evolved to be so strong!”

Perched on a tree branch, Uchiha Mikoto gasped for breath, gravely watching the monster in the distance, while Uchiha Yoru frowned secretly, constantly recalling information in his mind.

In the original work, Orochimaru also discovered Zhongwu’s existence in the later stages and developed the cursed seal.

This clan is not a bloodline limit but a special sage body, as the inability to control the absorption of natural energy leads to rampaging.

Rampaging! Emotionally unstable!

Thinking of this, Uchiha Yoru made a decision and shouted:

“Mikoto, use genjutsu! This monster is emotionally unstable, clearly unable to control this power; use genjutsu to draw out its inner fears!”

With their innate trust, Uchiha Mikoto did not hesitate at all. Her eyes with double tomoe Sharingan spun rapidly as she formed hand seals.

Genjutsu: Demonic Illusion – Hell Viewing Technique!

In an instant, under the rain, the monster’s pupils trembled violently upon seeing Uchiha Mikoto's double tomoe Sharingan, and its deepest fears emerged.

“No! I didn’t kill everyone, don’t drive me away… no…”

Countless memories surged in its mind, and the monster roared madly, clearly filled with intense fear.

From its frantic words, it could be inferred that it was unable to control itself, had killed people from its own village, and was then driven out.

As its wandering spirit became increasingly unstable.

“Good opportunity!”

Seeing the monster’s relaxed and collapsed cries, Uchiha Yoru seized the moment and continuously shot kunai embedded with detonating tags.

He aimed for the monster's roaring mouth and throat—its vital areas.

Boom!

As countless detonating tags exploded, the monster’s frantic roars were drowned out in the explosion.

Uchiha Mikoto also let out a muffled groan, painfully covering her eyes, clearly showing how much mental energy the genjutsu had consumed, tears of blood streaming down her cheeks as they were fighting against natural energy.

Uchiha Yoru seized this opportunity, drew out his ninja blade, and quickly vanished into the smoke.

“No… I didn’t kill everyone, I didn’t…”

Pff!

As blood splattered, a ninja blade pierced through its throat. The monster, with half of its body blown off, still weakly uttered,

“Forbiddance Technique: Perfect Version of the Demon Seed Technique!”

Using the smoke as cover, Uchiha Yoru had already unleashed this forbidden technique that had been sealed in his mind for twelve years.

He raised one hand, and a unique diamond-shaped seal appeared in his palm, pressing it swiftly against the monster’s forehead.

In an instant, the palm seal emitted a powerful sucking force.

This force was continuously devouring the monster’s special body power.

At the same time, the monster’s monstrous form was visibly receding, revealing its original appearance.

A withered, white-haired old man, devoid of any chakra, but capable of transforming into a monster after absorbing natural energy.

“Yoru!”

With a loud shout, as the smoke gradually dissipated, Uchiha Mikoto rushed in with concern.

However, when she entered, what she saw was a mutilated body pinned to the ground by a ninja blade through its throat.

“I didn’t kill… e-everyone…”

The rain washed away the blood, and the old man kept hoarsely repeating, his pupils beginning to dissolve.

At this moment, Uchiha Yoru was gasping for breath, looking serious, while his heart was secretly shaken.

After all, the other party was an ordinary person with no chakra at all; it was not like Zhongwu had the strength of a proficient jōnin, and at such an old age, this cursed sage body was truly terrifying.

“Mikoto, this information is wrong. If it weren’t for the fact that we brought enough detonating tags this time, both of us might have fallen here.”

In response to Uchiha Yoru’s teasing, Uchiha Mikoto’s Sharingan was fixed intently on the lifeless figure.

Uchiha Yoru sighed deeply, the diamond seal in his palm gradually disappearing, replaced by the faint lines of a seal beneath his skin, which then blurred and faded away.

The perfect version of the Demon Seed Technique can devour and fuse bloodlines, but this perfect version requires a substantial amount of time and stabilizing genetic agents to gradually allow the body to fuse and adapt.

The forbidden technique is the perfect version, but it still requires investment in the later stages; thinking of this, Uchiha Yoru cursed silently, it’s all a setup.

Originally, his plan was to use someone from his clan who had awakened their eyes, as the rejection force of the same clan’s bloodline is small.

But this cursed sage body is truly a rare find.

Moreover, he wanted to verify a hypothesis of his, and it just happened to fit into Tsunade’s plan.

With that thought, Uchiha Yoru revealed a serious expression.
