"The strength of the night owl is really terrifying, and he dares to go straight into the Nine Hells Demon Vortex. They secretly said in their hearts, and then they flew towards the sky above the Nine Hells Vortex, Ye Feng sank in the depths of the black Vortex, no one paid attention to him at all, in the eyes of the night owls, Ye Feng He was just a passing tourist who practiced some kind of special magic skills, his little strength was naturally not in their eyes, and their purpose was the Nine Hells Demon Vortex.

The powerhouse of the Nine Prisons Mansion is waiting, Ye Feng is sinking in the depths of the whirlpool, and it is not easy to force him to rush up, in case he angers them, the exit is blocked, it is not easy to escape, and he is also about to bundle their true purpose, so he will wait patiently.

As time passed, the fluctuations under the black vortex became more and more intense, and wisps of stronger death energy rushed out, making Ye Feng faintly feel unbearable.

"Boom!" At this moment, in the depths of the whirlpool, a dull explosion sound attracted Ye Feng's attention, his eyes looked towards the depths of the Nine Hell Demon Whirlpool, only to see a black undercurrent burst out, he hurriedly swam to the side, the undercurrent grazed his side and rushed up, above him, I saw the body of the night owl soaring into the sky, and the Nine Hells Vortex below him, there was a black air flow straight into the sky, as if a terrifying force erupted.

"Bang la!" The black whirlpool seemed to be furious, and it spun rapidly, and it became extremely turbulent, impacting Ye Feng's body, Ye Feng puffed up the qi in his body, like a mainstay, trying his best to stabilize his body, his eyes kept staring upward, only to see that the black air flow rushed straight above the sky, like a waterfall going upstream, and suddenly the whole sky seemed to turn into a pitch-black world!

"It's so terrifying, how was the Nine Hell Demon Vortex born, the bottom of this Nine Hell Demon Vortex, I don't know where it leads?" Ye Feng looked at the sky that had completely fallen into darkness, and a terrifying Nine Hell Demon Qi spread out in all directions, completely covering the heavens and the earth, Ye Feng's eyes swept into the distance, I am afraid that a radius of hundreds of miles will become a world of death.

Rumble...... A stronger black torrent rushed up from below towards Ye Feng, and the Nine Hell Demon Vortex let out an earth-shattering roar.

"Whoosh!" Ye Feng didn't dare to slack off, his body broke through the air, that terrifying black torrent, if he didn't hide, he could be killed.

I saw that the night owl's body was in the air, and he actually stepped directly into the sky above the torrent of the Nine Prisons, looking at the black torrent gushing out, his eyes flashed with joy.

With a wave of his right hand, the Nine Hell Demon Gourd in his hand suddenly flew out, suddenly expanded, and turned into a huge gourd, from which a powerful and terrifying devouring power came out, and in an instant, the black torrent against the current frantically went towards the gourd, and was swallowed into it.

"The essence of the Nine Hell Demon Vortex. "The powerhouses of the Nine Prisons Mansion stared at the black torrent that erupted with fiery eyes, and the Nine Hells Demon Liquid that was devoured at this moment was the essence of the Nine Prisons Demon Vortex.

"It turns out that the Nine Prisons Mansion followed the Nine Prisons Demon Vortex, and the purpose of pursuing this is to collect the essence of the Nine Prisons Demon Vortex, no wonder they have not invaded the Holy Fire Country for so long...... "Ye Feng saw this, and his heart suddenly realized, what he had been vigilant about recently was that the army of the Nine Prisons Mansion appeared on the land of the Holy Fire Country, and for this reason, he did not hesitate to dismiss the people in the palace who did not want to leave, and was willing to follow him into the small world in the body, and what he was prepared for was that the army of the Nine Prisons Mansion suddenly entered the world......

But after waiting for several months, there was no sign of invasion, so he could only take the risk, disguise himself as a tourist, and come to inquire about the situation in person.

At this moment, he saw the purpose of the Nine Prisons Mansion clearly, the black torrent that the demon whirlpool spewed out, full of death energy, made him dare not bear it, and had to escape immediately, it can be imagined how attractive it is to the strong people of the Nine Prisons Mansion, this kind of black torrent that normal people will die once they touch it, for a strong person like Ye Feng and the Nine Prisons Mansion, it is simply a great tonic, but the black torrent that spews out contains obviously a more high-level death energy, so strong that Ye Feng does not dare to bear its impact......

And the night owl was full of joy, and vigorously urged the space gourd to collect it, obviously treating it as a rare and scarce treasure of heaven and earth, and the night owl is an emperor-level powerhouse, it is conceivable that the essence of the demonic qi that spews out should be an emperor-level energy......

Only in this way did Ye Feng not dare to block with his body, so he could only flee in a hurry. Otherwise, the death energy contained in it is too high-level, and his body can't bear it, and he will be instantly spewed out by the black torrent, which will dissolve the bones and muscles, and he will die with a whimper.

It seems that the Nine Hells Mansion, under long-term observation, should finally find out the mystery of the Nine Hells Demon Vortex spewing the thin emperor-level death qi, and follow the Nine Hells Demon Vortex everywhere to find its newly opened source, the purpose is to wait for it to spew out the emperor-level death qi, and then treat it as a cultivation treasure. If this conjecture is true, after the phenomenon of the Nine Hells Demon Vortex spewing out emperor-level death qi disappears this time, this group of pathfinders in the Nine Prisons Mansion should retreat along the same path.

Although the Holy Fire Country is good, it is obviously too desolate, and the aura that permeates from the small world of the Lotus Emperor does not help the powerhouses of the Nine Hells Mansion at all, but is regarded as a great poison, just like the Holy Fire Warrior, they will definitely regard the magic vortex qi as a great poison, and those who touch it will die.

I hope that after they receive this black essence, they will quietly leave, so that this crisis in the Holy Fire Country will disappear invisibly...... Ye Feng stared at the night owl who had received the black essence, and secretly looked forward to it in his heart.

"Boom!"

After a long time, in the depths of the magic whirlpool, there was a dull popping sound, as if something was collapsing, and then, the black torrent that erupted suddenly became thinner, and the momentum decreased sharply...... Ye Feng guessed that this might be like a volcanic eruption, although the magma suddenly erupted and destroyed everything, but after all, it was a fierce momentum, coming fiercely and going fast, maybe the essence of the Nine Prisons was also like the magma erupting, and it was about to end this eruption......

At that time, the group of strong people in the Nine Prisons Mansion who can be seen will leave or stay...... As soon as Ye Feng thought of this, his spirit was lifted and he looked at it intently.

He saw that the Nine Prisons Demon Gourd had obviously slowed down, and the night owl's happy face became a little displeased, as if he thought that the Nine Prisons Essence collected this time was too small...... Ye Feng secretly wondered, he didn't know how much black essence the Nine Hell Demon Vortex had sprayed in the past, how much would it be? Anyway, he looked at the night owl's face, obviously quite dissatisfied......

Buzz rumble......

In the depths of the demon vortex, the muffled sound continued, and suddenly, the fountain-like black air flow suddenly disappeared, and in its place, it was the huge Nine Hell Demon Vortex, which fluctuated violently, as if a large pot of water was boiling, and countless gurgling bubbles were gushing wildly......
