Mu Feifei and the rest of the Array Refiner Guild fled first and were not so seriously injured, but the other Array Refiners were either dead or seriously injured, and none of them were relatively intact.

After a mutation, even if Mu Feifei and the other refining masters of the Array Master Guild were not seriously harmed, they were still terrified in their hearts, and they still had palpitations when they looked at the ancient cave, and they didn't come back to their senses for a long time.

And those who were too badly injured were in a mess, their hair curled and a strong smell of burning wafting out, their robes were tattered, there were a lot of burns, their eyes were empty and gray, and their outfits could be described as extremely miserable. They didn't expect that what was supposed to be a good experience would cause them to lose so much.

Even if some of them are lucky enough to escape death, with their current strength, they will not be able to recover without ten days and half a month, so in other words, if the formation of the ancient cave is finally cracked, then this trip to the ancient cave will not have their share, let alone the unknown treasures inside.

Thinking that he had been busy for most of the day, and finally didn't even have a chance to enter the ancient cave, the old blood of those seriously injured array refiners was about to vomit out.

There is a strong unwillingness in my heart, but I am helpless.

Mu Feifei, who came back to his senses, looked at the ancient cave entrance, and the violent energy burst out from the defensive array.

At that time, they were still immersed in the structure and mystery of the formation, and this is also the root of breaking the formation, otherwise it would be a fool's dream to try to crack the formation without even understanding the most basic structure of the formation.

Just when everyone was attracted by the subtlety and exquisite structure of the runes on the formation and lost themselves, suddenly a subtle and invisible fluctuation emitted a subtle hum in the depths of the formation, if it weren't for Mu's extraordinary soul power and strong perception ability, he really wouldn't have been able to detect the dangerous aura coming from the fluctuation.

In the end, Mu Feifei's roar could have made all the array refiners leave this dangerous area in an instant, but those genius array refiners of various sects refused to give up this enlightenment at this dangerous juncture, and thought that Mu Feifei was making a fuss.

But by the time they really smelled the danger that had emanated from the fluctuations, it was too late, and even if they were quick in the end, they still paid a great price.

As the Array Refiner Guild, the Array Refiner didn't have any hesitation after Mu Feifei yelled, and directly cut off Shen Wu and retreated with Mu Feifei, because they believed that Mu Feifei would not lie to them, and they completely trusted Mu Feifei, so they only had a slight injury.

Now, some time has passed since the violent energy subsided, but Mu Feifei and they are still in a state of panic, and they dare not take half a step.

At this time, the smoke and dust were still rolling in the ancient cave, and it was impossible to see whether the defensive array had been cracked.

"Let's hope that one last time will succeed, otherwise it will really fall short. ”

Mu Feifei looked at the entrance of the cave and didn't look away for a long time, before the humming sound sounded, Mu Feifei had already finished analyzing the last bit of the structure of this formation, and even the mysteries in it were comprehended, which showed how high his talent was.

Just as he completely analyzed the structure of the formation, he immediately cracked the formation layer by layer, and just as he was about to finish cracking the formation, the humming sound sounded, which had to make Mu Feifei, who was aware of the danger, leave immediately.

And those who left later were not so lucky, those who were able to escape alive were all seriously injured, and they could hardly stay any longer, so they had to find a quiet place to recuperate as soon as possible.

Now Mu Feifei's only hope is that he has successfully cracked this defensive array.

What he hoped for was also what a group of top powerhouses on the highlands wanted, but it was not within their scope of consideration whether those array refiners were seriously injured, which showed that these people's hearts were indifferent in the face of interests, not only that they had this phenomenon in almost the entire continent.

Although they hoped that the defensive array had been broken, they still tensed their nerves and tried to suppress the excitement in their hearts.

A pair of fine eyes stared at the smoke of the ancient cave, as if they didn't want to miss anything.

Not only them, but even Nangong Huayi stared intently at the ancient cave, as for those injured array refining masters, they would give them some benefits later, and those who died, even if their lives were not good, who would care about a dead person.

Xie Aoyun and his group were also shocked by the violent energy, after all, no one expected such a change.

The thick smoke at the ancient cave gradually dissipated, and the situation at the entrance of the cave became clear, but when Mu Feifei saw this scene, his pupils shrank tightly, his whole heart sank slightly, and his face showed an abnormal unwillingness.

And Nangong Huayi's originally nervous expression when he saw the situation at the entrance of the cave was instantly replaced by heaviness, and the unwillingness in his eyes was even stronger than that of Zhi Mu.

The others were also secretly stunned when they saw this, and there was a deep disappointment in their hearts, it seemed that this time they were going to run in vain.

At the entrance of the ancient cave, there were ripples that continued to rise and fall, obviously a formation, but it was different from the previous defensive formation.

The heart-palpitating energy fluctuations on this formation are exactly the same as the violent energy just now, which means that the violent energy just now is the burst out of this formation, which is a very tricky attacking formation!

Seeing that this formation has obviously been activated, it may be that these formation refiners accidentally touched something when they cracked it, which caused this formation to burst out with violent energy!

"It seems that this trip to the ancient cave is not as simple as imagined!"

Xie Aoyun was also shocked by the attack formation at the ancient cave, and this attack formation was even more tricky than the previous defensive formation, the defensive formation could reduce the enemy's offensive to achieve the minimum damage, but it was not offensive at all.

However, this offensive formation is different, and when the enemy attacks it, it will also produce a corresponding, even more deadly, offensive towards the enemy.

And if you want to crack this type of formation, you can't use the previous method of breaking the defensive formation, after all, this offensive formation will have a strong counterattack on anyone who wants to destroy it.

"I wonder what they're going to do next? But this ancient cave really whetted my appetite. ”

Xie Aoyun's mouth raised a slight arc, and he gloated at Nangong Huayi's ugly look, but this ancient cave aroused Xie Aoyun's strong curiosity, a good defensive array can show that it is not simple, but then a more tricky attack formation appears, what can it mean? This shows that this ancient cave has an unexpected wealth in it, and this wealth is enough to cause a bloody storm on the side.

But this also left Xie Aoyun and them a heart, which was mainly aimed at Nangong Huayi and the top former who didn't know each other.

"It's a good show!"

At this time, Yi Chengfeng also interjected coldly.

"It's a good show, but it's definitely not a show, and we must also be vigilant against Nangong Huayi, and we must not have the slightest intention of relaxation. ”

The cold light in his eyes moved, Xie Aoyun looked at Nangong Huayi and said in a condensed voice, he didn't understand Nangong Huayi, but he could perceive that Nangong Huayi would definitely not be simple, especially since they were still enemies, and they would definitely not make Xie Aoyun and the others feel better.

Swish!

On the high ground, Nangong Huayi stomped on the ground with his legs, and the whole person turned into an afterimage.

"How's it going?"

Although this attack formation was even more terrifying than the defensive formation, but at this point, he didn't want to give up in vain, but after all, he was not a refining formation, so he came to ask Mu Feifei.

"Although this formation is higher than the previous defensive array, it has also not withstood the tempering of the years, this formation is more difficult to crack than the defensive array, and someone has to transfer its attack target, otherwise there is no possibility of cracking. ”

Mu Feifei pondered for a moment and said slightly, through his observation, the prototype of this attack formation was definitely not something that a six-star refining array master like him could crack, but in the river of years, its aggressiveness had been greatly reduced, and it no longer had the power it used to be.

"So what can be done to divert its target?"

Nangong Huayi nodded and agreed with Mu Feifei's statement, he didn't want to have a situation where the treasure was in front of him but he couldn't take it.

"Ask twenty or so top powerhouses to attack this formation separately and divert the attack of the formation, so that I can figure out its structure before breaking the formation. ”

Mu Feifei directly said his plan, not that he wanted to harm those martial artists, but it was indeed his best plan, otherwise who would do something that would throw away his life before he really started?

Of course, it doesn't mean that those top powerhouses should be sent to death in vain, they just need to attract the attack of the formation, and don't resist hard.

Therefore, this time, only by cooperating with each other can it be possible to break this formation.

Nangong Huayi raised his eyebrows slightly and looked at Mu Feifei deeply, but the latter was surprisingly calm and did not have any discomfort, he naturally knew that his words would cause people to have a trace of prejudice, so he also looked at Nangong Huayi casually and smiled slightly.

"Okay, as you said, I will ask someone to cooperate with you to break the formation, I hope we have a happy cooperation!"

I couldn't see anything, Nangong Huayi didn't think about it anymore, stretched out an arm and said slightly, although he was biased against Mu Feifei's words, he couldn't think of the reason, and finally agreed to Mu Feifei's plan, but he still had a heart for Mu Feifei in his heart.

After all, this is a matter of their own life, who would want to put themselves in a deep crisis?

"Happy working together!"

Mu Feifei saw Nangong Huayi stretch out his right arm, grinned, and he also stretched out his right arm to shake Nangong Huayi's hand.

He didn't care what Nangong Huayi thought at this time, he just didn't want to let himself run in vain.
