Chapter 3658: Underworld

"The Underworld, finally unable to hold back anymore?"

Looking at this black-robed person, Jun Xiaoyao didn't feel surprised.

Rather than saying that, the Underworld finding him now was what made him slightly surprised.

As early as in the Nine Heavens Immortal Realm, he had had quite a few grievances with the Underworld.

And now that he had come to the Vastness.

With Jun Xiaoyao's rising fame.

He knew that the Underworld of the Vastness Starry Sky would definitely target him.

As for why the Underworld targeted him.

Besides those past grudges.

He estimated it was also related to his own innate constitution.

After all, the Underworld had been collecting various precious blood constitutions for countless years, conducting mysterious experiments, and had big plots.

"Underworld, even if you didn't come to find Jun, Jun would one day go to find you."

"But unfortunately, it is not now." Jun Xiaoyao said indifferently.

"Whether you go or not is not up to you."

The black-robed person's voice was low and hoarse, as if the demonic sounds of countless wronged souls were ringing out.

"This time, the Underworld only sent you alone?"

"Or is it that you are quite confident in yourself?" Jun Xiaoyao said.

The black-robed person's expression remained dead and silent, without any extra emotion.

"I am the Underworld's No. 28 experimental product, Chang Gui."

The black-robed person looked at Jun Xiaoyao with red eyes, and finally revealed his identity.

"Underworld experimental product..."

Jun Xiaoyao's eyes froze slightly.

He thought of Ye Tong.

Ye Tong's identity was the Underworld's No. 7 experimental product.

Once, Ye Tong had also told him.

In the Underworld, there existed many experimental products.

Those experimental products were not like ordinary cultivators.

Just strong in realm or combat power.

But every one of them was incomparably bizarre, having all kinds of special features.

They were alien existences cultivated by the Underworld through various means.

These Underworld experimental products could not be measured with ordinary eyes.

"Chang Gui..." Jun Xiaoyao murmured to himself.

The so-called Chang Gui refers to the ghost of a servant who was eaten by a tiger and became a tiger's servant.

There is an idiom called "acting as a tiger's servant," which refers to Chang Gui.

Clearly, this Underworld No. 28 experimental product should not be simple.

"My only instruction is to bring you back to the Underworld."

Chang Gui looked at Jun Xiaoyao, without the slightest hesitation, and took action directly.

Behind him, monstrous evil aura surged out, rolling in the void.

A boundless black tiger phantom actually emerged, opening its tiger mouth, as if it could swallow billions of galaxies.

One could even see countless living beings as if they had already been swallowed into the black tiger's belly.

Endless wronged souls and ghosts were wailing.

Chang Gui took action, black evil aura surged, like a vast sea tide, covering the sky and surrounding Jun Xiaoyao.

Around Jun Xiaoyao, a hundred-fold magic power immunity divine ring emerged, like layers of worlds, isolating the attack fluctuations.

At the same time, on his body, endless sword rays soared to the sky, and the sharp sword momentum cut through the evil aura tide.

*Boom! *

The two figures instantly collided, and the ripples were endless.

"That person is..."

Yao Li's eyes revealed a strange look.

This Jun Xiaoyao was his prey after all.

Unexpectedly, someone had actually gotten there first.

"This Jun Xiaoyao is really a person who causes trouble; I don't know how many enemies he has provoked."

"But this is also good; first weaken his power, it can be more convenient to solve him."

Yao Li was happy to see the result, temporarily suppressing his actions.

*Boom, boom, boom! *

Chang Gui took action, and endless evil aura surged.

The boundless black tiger phantom behind him, after swallowing many living beings.

Became as if it were real.

The blood-red tiger eyes were like two blood moons.

Opening its mouth to roar, the terrifying tiger roar sound wave directly shattered ten thousand miles of void.

"Dark Sacred Tiger."

Looking at that black tiger, Jun Xiaoyao's eyes revealed a strange look.

The Dark Sacred Tiger was also an extremely terrifying monster, feeding on flood dragons.

And a Dark Sacred Tiger that

It was likely of an extremely ancient age.

If it were a true Ancient Dark Saint Tiger, its strength and realm would be at a crushing level among its peers.

The vengeful spirit charged toward Jun Xiaoyao.

The pitch-black tiger claw slammed down like a black world-destroying millstone, shattering the void in that area.

Jun Xiaoyao raised his hand, endless magic power erupting and brilliance overflowing, as if resisting.

A strange light flickered in the depths of his eyes.

His figure retreated.

The vengeful spirit continued to attack.

Seeing this, a faint trace of surprise also appeared in Yao Li's eyes.

"How does this black-robed person's aura feel related to that mysterious Underworld? It really isn't simple."

"But it seems that even someone as strong as Jun Xiaoyao is having difficulty resolving this for the moment."

"Sure enough, how can there be a truly invincible person in this world."

Seeing Jun Xiaoyao no longer possessing that overwhelming dominance, Yao Li felt even more settled in his heart.

In this way, his confidence was even greater.

Seeing Jun Xiaoyao and the vengeful spirit fight into the distance, the void along the way collapsed, as if the Dao itself were about to be obliterated.

Yao Li, Dan Lin, and the others also secretly followed behind.

The entire Sky Ruins was vast and boundless in scope.

The great battle between Jun Xiaoyao and the vengeful spirit directly moved away from the entrance to the Dan Realm.

They arrived in a void universe.

After arriving at this place.

Jun Xiaoyao directly unleashed the Seven-Colored Heaven-Slaying Gourd.

The Great Luo Sword Embryo erupted from within, accompanied by the innate laws of the Killing Dao.

Unparalleled sword Qi was boiling.

Further empowered by the Sword Dao Heavenly Heart artistic conception.

Jun Xiaoyao slashed out with one sword, like a flying immortal from beyond the heavens, the ten-thousand-li void along the way annihilated into dust within the sword radiance.

The released fluctuations directly shattered the surrounding broken continents into powder.

With one sword sweep, the vengeful spirit let out a roar within the sword radiance, its figure turning into fly ash inch by inch.

"This..."

Not far away, Yao Li, who had been tracking them, froze in his expression.

Was Jun Xiaoyao intentionally feigning weakness just now to lure them here?

And just as Yao Li was feeling suspicious.

He saw the void rumbling, endless baleful Qi flowing, as if it were about to drown all worlds.

"Jun Xiaoyao, you cannot kill me..."

Within the endless baleful Qi, the figure of the vengeful spirit appeared once more.

Not one, but ten, a hundred, a thousand, ten thousand.

In just a fleeting moment.

Jun Xiaoyao had destroyed the vengeful spirit with one sword.

Yet the result was over ten thousand vengeful spirit figures emerging densely within the baleful Qi, surrounding Jun Xiaoyao.

"The Underworld's experimental subjects really do have some eerie aspects."

Jun Xiaoyao's expression never changed much.

Clearly, he hadn't thought that one sword would directly kill the vengeful spirit earlier either.

"Jun Xiaoyao, the capabilities and means of my Underworld far exceed your imagination."

"If I could bring you back."

"With the Underworld's methods, I could transform you into the most powerful existence throughout history."

"Perhaps you could become a world-destroying level experimental subject."

"That would be your supreme honor."

The demonic sounds of ten thousand vengeful spirits came from all directions.

Jun Xiaoyao, upon hearing this, gave a calm smile.

"World-destroying level experimental subject?"

"That sounds quite intimidating."

"Unfortunately, I am quite satisfied with myself and feel there is nothing that needs to be transformed."

"Furthermore, if you think that relying on these clones and smoke screens can leave me helpless against you."

"Then I can only say that while the Underworld can transform your strength, it cannot improve your IQ."
