The surging gray shadow was frantically condensed behind the two Liu brothers, and in less than a moment, it had already formed an illusory demon beast. The appearance of the demon beast was impossible to see clearly for a while, but faintly, an ancient and strange fluctuation spread out from the demon beast's body, causing people to be troubled for a while.

And just when this illusory demon beast phantom was condensed, a low shout came from the mouth of the Liu brothers: "Great Wilderness Shura Hand!"

The sound of low shouts fell, and I immediately saw that above the illusory demon beast body, an arm suddenly stretched out strangely, and then it directly tore the void, like the most violent meteor, carrying extremely terrifying fluctuations, and roared towards the place where Du Fei was!

As soon as the arm appeared, it directly blocked all of Du Fei's retreats, and such a momentum was terrifying to the extreme!

Du Fei squinted at the strange arm that pierced through the void at this moment, and in an instant, the surging colorful light suddenly condensed on his body, and then, he saw the phoenix wings behind Du Fei slammed into a fierce fan, and then carried the wind and thunder, thinking fiercely about the front fan.

"Heavenly Phoenix Wind Thunder Wing!"

"Bang-"

The two wings of wind and thunder were thrown out like meteorites, and the thunder and snow in the sky swept away in an instant, and then collided with the strange arm that roared together!

It's just that in the blink of an eye, I saw that the wind and thunder wings that should have been indestructible suddenly trembled slightly, and a trace of cracks quickly appeared above, and then Du Fei's figure was also shocked, and he was thrown out like a meteor in an instant, and directly hit a thick branch, which can be regarded as stabilizing his body. But even so, at this moment, cracks are also floating on the branches of this big tree, and on the Tianfeng Armor on Du Fei's body, Dao cracks are also beginning to appear!

With one move, he can break his Heavenly Phoenix Armor, and this kind of opponent is really rare!

Standing up slightly embarrassed, Du Fei raised his head violently, looked at the Liu brothers with a sneering face at the moment with a slightly strange gaze, and suddenly grinned: "Okay! Sure enough, it's a good skill, the ability of the two demons of the Liu family, I can be regarded as a teacher today! However, because of this, I want to kill you even more!"

When the voice fell, the mark in Du Fei's hand changed, and his hands suddenly spread to the sides, and in an instant, he saw that the Heavenly Thunder Pill and Ice Lotus Pill, which were originally suspended above Du Fei's head, were actually rotating rapidly at this moment, and then, an ice crystal and a thunderbolt roared out almost at the same time, directly in the crown of this big tree, forming a formation, and the moment the formation was formed, it was also an instant enveloping the two Liu brothers. At the same time, a terrifying coercion belonging to the Heaven and Earth Yuan Dan also permeated from that formation.

"Dan Divine Formula! Refining the Heavenly Divine Array!"

At the moment when the formation was formed, Du Fei's voice slowly came out.

Feeling this fluctuation and hearing Du Fei's voice again, in an instant, a look of horror appeared on the faces of the two Liu brothers.

The Dan Divine Formula's Refining Heavenly Divine Array, the legendary number one array that can even refine heaven and earth, obviously, this Liu brother has also heard of such rumors, but they didn't expect that Du Fei, who had just learned the Dan Divine Formula, would actually use this Heavenly Refining Divine Array.

"Sneer—"

Below, dozens of feet of ice spread all over the ground, turning the entire ground into a frozen world, and an astonishing cold air permeated from it.

"Boom—"

In mid-air, the whistling thunder light was like a thunder dragon, constantly hovering between heaven and earth, enveloping the Liu brothers, and where the whistling thunder dragon passed, there was a scorching smell in the air, which made people understand what terrifying power was contained in this thunder.

This Heavenly Refining Divine Array is one of the killing moves in the Dan Divine Formula, if Du Fei's strength is stronger, he can even directly pull people outside the formation into the formation, and then be refined by the Danhuo, even if the strength of these people is strong, they will slowly turn into ashes.

Of course, the current Du Fei's comprehension of the Dan Divine Technique is not profound, and it is also with the help of the power of the two Heaven and Earth Yuan Dan that he can deliberately introduce these two people into the formation. But even so, this Heavenly God Refining Array is enough for these two guys to eat.

On a piece of ice, the thunder dragons continued to roar, and with the roar of the thunder dragons, the formation seemed to be gradually converging.

The two Liu brothers who were trapped in the array, their faces at the moment were also a little complicated looking at this ever-changing strange array, but this thunder and Xuan Bing did not make them afraid, what made them feel scared was that at this moment, an inexplicable sense of fear enveloped their hearts, making them vaguely feel a little frightened.

"Let's shoot together and find ways to break this big array!"

However, although these two people are a little uneasy at the moment, but their experience is extremely sophisticated, after the two of them glanced at each other, in an instant, the extremely surging true qi instantly roared out, and the violent attack instantly fell towards the ground, in their opinion, it seems that it is easier to break through this Xuan Ice than to break through the thunder dragon roaring in mid-air.

"Click-"

A low sonic boom sounded, and where they slapped it with one palm, a crack suddenly appeared, but before the two of them had time to be happy, they saw that there were ice crystals in the crack in an instant, and in the blink of an eye, those cracks were filled. Obviously, this great array is still impregnable under their joint efforts.

"What a strong formation!" When the Liu brothers saw this scene, their eyes flashed with horror, obviously they didn't expect that this big array was so terrifying.

In mid-air, above the big array, Du Fei's mind controlled two Heaven and Earth Yuan Dan, and the Dan Qi of Heaven and Earth Yuan Dan was constantly converging into the formation at this moment, making the formation stronger and stronger.

Staring condescendingly at the two Liu brothers who were trapped in the formation, Du Fei sneered. Generally speaking, unless it is a nirvana, in order to cover up the fact that he has obtained two Heaven and Earth Yuan Pills, he will never use such means at will. However, since he has used such means at this moment, then no matter what ability these two guys have, they will all be consumed alive by themselves! Now, his biggest interest is, how long can these two guys hold out below?

"Aren't you interested in these two guys? Now, let them love you. ”

The words that seemed to be smiling fell, and the mark in Du Fei's hand changed, and in an instant, he saw that in the Heaven Refining God Array, on the ground, and above the Xuan Ice, the cold air began to permeate, causing the two Liu brothers to jump into the air violently, and then looked at the ground with a little horror. Because, at that moment just now, the cold qi in those dark ice was instantly astonishing to the extreme, making them understand that if they came into contact with these cold qi again, their fate would be extremely miserable.

However, even if they were suspended in mid-air, they could still feel that those cold qi were like sharp needles, constantly burrowing into their bodies, as if they were going to freeze all their meridians and true qi.

"This kid, what a terrifying method!"

The two of them glanced at each other in mid-air, and their eyes flashed with horror, obviously, it was the first time they had encountered such a powerful formation, such fluctuations, even the true qi in their bodies could be frozen.

Large drops of sweat kept dripping from the corners of the foreheads of the two, but as soon as they appeared, they turned into ice flowers. But even so, the two of them still continued to urge the true qi to resist the cold qi entering the body, obviously, they both understood that in this case, if something happened in the body, then it was really certain death!

"Boom—"

And just when the two of them were struggling to resist the erosion of the cold air, the thunder in mid-air had quickly condensed together, and in the end, two huge thunder dragons were directly formed, and then they swam wildly, and waves of extremely terrifying fluctuations emanated.

"Go!"

At the moment when the thunder dragon was formed, Du Fei's eyes were cold, and then he pointed a little forward, and in an instant, he saw two thunder dragons carrying extremely terrifying attacks, roaring towards the place where the Liu brothers were!

At the same time, the terrifying cold air also became more and more cold, making the Liu brothers feel a little tingling in their breathing at this moment.

Such a change caused the Liu brothers' complexions to change dramatically at the same time, and then they saw the imprints on their hands change rapidly, and in an instant, gray shadows appeared behind them again.

"Humph!"

Looking at this scene, Du Fei sneered, and then shook his palm, and in an instant, a cold air swept again, causing the mark in the hands of the two to suddenly stiffen, and the martial arts that were about to take shape instantly exploded.

"Boom-"

And at the same time, the two thunder dragons had already roared, and then in the disbelief of the two of them, they slammed into their bodies!

A low muffled sound instantly resounded, directly smashing the two figures to the ground, and the moment they landed, the ice crystals spreading on the ground instantly covered them, causing their entire bodies to become stiff in an instant.

"Since it's in my hands, you don't want to run away. Du Fei stared faintly at the two of them who were embarrassed to the extreme at the moment, and there was a slight burst of secret joy in his heart. Unexpectedly, this Dan Divine Trick combined with the Heaven and Earth Yuan Dan, can actually exert such power, without using the Heaven and Earth Yuan Dan, he can't use this trick at all, and it takes a lot of strength to defeat a Xiang Tian, but I didn't expect that at this moment, fighting with these two guys, he can actually tell the winner so quickly. It seems that the Heaven and Earth Yuan Pill is really terrifying, no wonder everyone wants to get it! If he gets the Melting Heaven Pill, then wouldn't he be able to make his strength even more terrifying?
