The space in front of them seemed to be an old battlefield that had been eroded by the years, and in such a tragic situation, even after so many years, Yu Feng and the three of them could still clearly feel the cruel battle situation of the battle at that time.

"W-what's going on?"

Yu Feng and the three of them were also completely stunned by the scene in front of them, the three of them came to the red battlefield, and they could still smell the smell of blood in the air in their noses, and no one seemed to have touched here, their robes were all kept intact, and the previous battle situation seemed to have been completely frozen.

"Sure enough, it's the Demon Eater~!"

Looking at the clothes of the corpse below, Ao Yun also said hatefully, between speaking, his eyes were already covered with dense blood, and the green tendons on his forehead appeared, hatred, anger was also in Ao Yun's heart, in that Ao Yun's heart, he didn't want the destruction of the underworld to be related to the Demon Eater, after all, the destruction of the Qin Clan before was the handiwork of the Demon Eater, and now, if the destruction of the Netherworld is still related to the Demon Eater, is it possible that the destruction of the ancient race is related to the Demon Eater? The Demon Eater is also too terrifying, and the terrible thing is that Ao Yun is terrified in his heart, and there is a trembling color between the words.

"Is it the Demon Eater again?"

Hearing the voice of the Ao Yun, Yu Feng also set his eyes on the corpse of one of the Demon Eaters, at this moment he was also secretly amazed in his heart, it seems that Yu Feng's understanding of the race of the Demon Eater is far from enough, even now, I am afraid that the horror of that race is far beyond his imagination, Yu Feng's emotions in his heart are undoubtedly complicated, after all, this is what he will face in the future, now it seems that this is an extremely difficult opponent, its strength is so strong, even if it is exterminated, the actions in the secret are also very terrifying, even, until now, so many years have passedThe style of that race is too insidious and cunning, and every move is very vicious.

Before, whether it was Yu Feng, Ao Yun, and Zi Zhu Feng, the three of them didn't want the destruction of the underworld clan in this place to have anything to do with the demon devouring clan, but now it seems that it backfired.

"Tsk, this Demon Eater, I haven't been idle for so many years, it's really terrifying~!"

Even Ao Yun couldn't help but sigh now, staring at the pieces of the Netherworld, the corpses of the Demon Devouring Clan almost covered the entire space, it can be imagined how fierce the fighting level would be at that time, and now Yu Feng and the three of them are almost completely certain that the demise of the Netherworld Clan in that place is definitely related to the Demon Devouring Clan.

"Hmm, something is wrong~!"

Suddenly, Aoyun's face was also condensed, and the next moment he also lowered his voice and said, the words came out, Yu Feng and Zi Zhufeng couldn't help but entangle, looking at that Ao Yun, the latter also didn't have time to communicate with that Yu Feng and Zi Zhu Feng, and the next moment, he was also standing on top of the void, looking down, it didn't matter, that Ao Yun also had a surprised expression, his eyes were wide, as if he was about to fall out of his sockets, and then, there was a flash of excitement on his face, followed by a sad look。

"You two come up and have a look~!"

Soon, that Aoyun also said to Yu Feng and Zi Zhufeng, hearing this, Yu Feng and the two did not hesitate, and the next moment they came to the void, looking down, looking down, looking at it, the scene in front of them was not the same expression as Ao Yun before, on the contrary, they were puzzled and puzzled, in the sight of the two people, they also found that all the corpses on the ground were also arranged, and the runes on the sacrificial square before were the same lines, constantly colluding, staggered, without the slightest trace.

"This, this, this, what's going on, this ......"

Yu Feng was also shocked.

"Together with the runes of the sacrificial square above, with the help of that power, the two realms of yin and yang are formed, with the underworld below and the Xuanyang realm on top~!

Aoyun frowned, his eyes were also looking at the scene of the sea of corpses below, and he immediately said.

"What kind of array is this?"

For ancient races such as the underworld, Yu Feng and Zi Zhu Feng certainly don't know as much as Ao Yun, and when they heard that Ao Yun talk about this formation, that Zi Zhu Feng also searched for the memories in his mind, and he didn't find any valuable clues, so he immediately let out a suspicious sound, and then asked.

It turned out that the so-called Yin Yang Hell Array was just a unique formation of the Netherworld, even if it was Aoyun, he had only heard it in rumors, and he had not seen it with his own eyes, and for the Netherworld, once this formation was used, it also meant that its entire race would be wiped out and wiped out。

"In my opinion, this outside world may have been searched by the Demon Devourer Clan a long time ago, but I didn't expect that there would be a cave under this~!"

Yang Tian sighed, and Ao Yun also said.

"Does this have anything to do with the Underworld Blood River?"

Yu Feng also took a long time to digest this information, shocked to shocked, but there was nothing to do, after all, these things had already happened, and he was powerless to change, of course, in terms of his strength, what could he change? Because of this, Yu Feng will also return to the topic, after all, this Stygian Blood River is the purpose of their in-depth in-depth into this red wilderness, the former base camp of low-sensitivity stocks, therefore, Yu Feng also asked.

"I don't know, maybe there is, maybe not, break the formation, you know if there is~!"

Hearing this, Ao Yun also shook his head, looked at the bottom thoughtfully, and Ao Yun also sighed and said, there are also uncertain factors in his words, of course, more of this is Ao Yun's own guesses.

"Break the formation, can you still break the netherworld constructed by this current formation?"

Hearing this, Na Yufeng couldn't help but gasp, and immediately felt his scalp tingle.

"What happens if you break the formation?"

Zi Zhufeng on the side also felt that this Aoyun's words were incredible, and immediately asked.

"I don't know about this, but now that we're here, do you think we're going to go back like this?

Ao Yun also smiled indifferently, as if he had everything under control, of course, in Ao Yun's psychological side, he also wanted to see what secrets were hidden under this formation.

Hearing this, Yu Feng and Zi Zhufeng also glanced at each other, and then the two of them also fell into a state of contemplation, and they were also weighing the pros and cons, of course, Ao Yun did not mean to force the two to make a decision, in fact, now this matter is in front of them There are these two choices, and these two choices are more like a gamble, or a gamble that they don't know the probability of winning or losing, and they are also at a loss for the result, and even don't know about the so-called concept of winning.

However, for Yu Feng and Zi Zhu Feng, they will not be willing to return in their hearts, they have returned in vain, they have wasted so much strength, they have not gained anything, and now they have turned the entire Red Wilderness up and down, and they have found nothing, and the only one that has something to do with the Blood River of the Earth is the sacrificial square, and this moment is also needed, Yu Feng and Zizhu Feng made a decision.

"Broken~~!"

After pondering for a moment, Yu Feng immediately said straightforwardly, with a determined look in his eyes.

For Yu Feng's answer, Na Aoyun was also very satisfied, and then the two of them also shifted their eyes to Zizhu Feng, waiting for the latter's decision, and at this time, Na Zi Zhu Feng also nodded and expressed this decision.

"This may be our last chance~!"

Looking at the formation formed by countless corpses below, Ao Yun also said lightly, of course, even if Ao Yun didn't say it, Yu Feng and Zi Zhu Feng also understood that if they couldn't find the Stygian Blood River after breaking this formation, I was afraid that they would really have no chance with them, and when the time came, that Zi Zhu Feng would be ......

However, for some reason, the three of Yu Feng had a sense in their hearts, and their intuition told the three of them that the Earth Netherworld Blood River was very likely to be under this formation, otherwise they really couldn't figure out why the sacrificial square was related to the Earth Netherworld Blood River, and the Earth Netherworld, which had already been invaded by the Demon Devouring Clan, was able to organize such a powerful force to activate a large array with a lethal power that was almost against the sky, and after thinking about it, there was only the Earth Netherworld Blood River.

Not only that, you must know that entering here is guided by the Seven Truths of Destiny, but the guardian beast of the Earth Hades will not harm them, after all, this may only be able to enter the Earth Hades here, because of this, Yu Feng has more reason to believe that this place is also relatively safe, of course, there are still risks.

"How are we going to break this formation?"

Yu Feng also asked.

"We can't help with this, we have to rely on your dragon veins and the Gangyu Thunder Sword in your hand~!Of course, the more important thing is the blood of the underworld~!"

Aoyun also said next.

Between speaking, Yu Feng had already mobilized the power of the dragon vein, his whole body was shining with golden light, and the Gangyu Thunder Sword in his hand also burst out with thunderous light, and the domineering thunder power was also constantly erupting from the Gangyu Thunder Sword.

Stepping on the void, holding the Gangyu Thunder Sword, the next moment, Yu Feng also dropped a drop of purple blood on the Yuan Fu blood cocoon on the Gang Yu Thunder Sword, and looked down calmly.
