Yangping Mountains, stretching for thousands of miles.

The belly of the mountain contains extremely rich earth fire, and many refining and alchemy monks like to use the earth fire resources here to refine treasures.

These fires are not only extremely hot, but also have stable throughput.

In terms of effect alone, it is only slightly inferior to the Dan Fire of the Jindan Monk.

It is also because of the abundant earth fire resources and the wide range that there are also many unique fire attribute ores and elixirs produced here, and the monks who come to collect them are endless. It is said that there are powerful demon beasts in the depths of the mountain range, and most of the monks who come here to experience it are in groups, and few people are left alone.

Yan Ning and Zhao Jinyun went around all the way, deliberately avoiding the others, and cautiously rushed towards the place shown on the map.

Beneath a steep mountain peak.

Zhao Jinyun took Yan Ning with a familiar car and stopped in front of an inconspicuous mountain crack.

The terrain is treacherous, surrounded by dense fog. The aura was not so abundant compared to the rest of the mountain range. If it weren't for the map, it's hard to imagine that there is a treasure hiding place behind this rift.

The two of them passed through an extremely narrow crack, and Zhao Jinyun waved at the cuffs of the stone wall that seemed to end in front of them.

A dark corridor suddenly appeared in front of the two of them, and it seemed that this was the 'Five Elements Lost Array' that he had set up since he left here last time.

For the concealed protection here, Zhao Jinyun really attaches importance to the abnormal.

The 'Five Elements Mystery Array' has to be arranged, and the consumption is not small, and it can't be taken without the cost of a few thousand spirit stones.

Then, I heard Zhao Jinyun say to Yan Ning excitedly: "Senior brother, behind this passage is the cave where the treasure is hidden." Although the area inside is not large, it is shrouded in the 'Thunder and Fire God Extinguishing Array', and Brother Wei was helpless last time, so he spread this 'Five Elements Mystery Array' here to cover up one or two. ”

With that, he walked ahead and walked straight into the dark passage.

Yan Ning nodded and followed without saying a word.

Walking into this pitch-black road, a scorching fire aura suddenly rushed to his face.

The road winds down to the belly of the mountain, and at its end is a space hundreds of zhang in size.

The hot magma tumbled in it, and the scorching flames erupted from the lava, making the temperature in the space extremely hot.

On top of a cliff deep in this space, a shabby-looking cave house sits there.

At first glance, you can see that it is quite old.

The mist that poured out of the magma below loomed over the Ink's Cave.

"Senior brother, this is the place. The cave on the cliff is shrouded in the 'Thunder and Fire Exterminating God Array', junior brother, you will know it as soon as you explore it. Zhao Jinyun said with an expectant look on his face, pointing to the top of the cliff.

Yan Ning also replied happily: "There is so much fire spirit here, it is indeed an excellent place to arrange the 'Thunder Fire God Destroying Array'. That cave mansion doesn't seem to have been damaged, senior brother is really blessed!"

Zhao Jinyun laughed when he heard this, and his excitement was beyond words.

After lifting their shields, the two of them crossed the tumbling lava below and reached the top of the cliff.

At the beginning, Yan Ning kept looking back and forth around the cave, and the sound of amazement came from his mouth from time to time.

But as time passed, it became frowning again.

After the initial investigation, it seemed that the situation was much more difficult than he had imagined.

With such an abundant supply of fire aura here, the power of this 'Thunder Fire God Destroying Array' in front of him was probably too great for him to estimate. If one accidentally triggers this formation, I am afraid that the space here will immediately be turned into ashes, and the two brothers and sisters will not be able to escape it.

"Senior brother, I still have to investigate carefully. The situation is a little different from what we estimated before, and it may take a lot of time. Yan Ning turned around and said to Zhao Jinyun with some caution.

After listening to this, Zhao Jinyun did not urge, but said happily: "It seems that the junior brother is somewhat sure, it's really good! As for the time, don't worry, it's very concealed here, senior brother, I'll go and strengthen the maze array outside, junior brother, you just have to rest assured." But don't rush in, be careful. ”

"Senior brother rest assured, junior brother can save it. Yan Ning nodded and returned.

After Zhao Jinyun finished speaking, he no longer disturbed Yan Ning, who was focusing on the formation in front of him. He took out a bunch of things from the storage bag and walked towards the passage from which he came. It seems that he wants to strengthen the Five Elements Mystery Array on the periphery according to what he just said.

Yan Ning looked at the surrounding environment, and after pondering for a moment, he also took out a few array flags of different colors from the storage bag. These small flags were engraved with all kinds of obscure runes, which he had taken the time to refine by himself before.

Next, he carefully planted these small flags around the Thunder Fire God Destroying Array, and outlined many complex patterns in the middle of several small flags, which were faintly similar to the patterns on the Hidden Spirit Array that he had obtained before.

After doing this, Yan Ning took out another jade seal-like thing, and beat it into the ground with a magic trick.

Then, his hands kept changing the magic tricks, and he shouted: "Get up!"

I saw that within a range of dozens of zhang around this cave, a thin transparent light curtain slowly rose from the ground, forming a shield to envelop the scope of this cave. This improved 'Hidden Spirit Array' was arranged by Yan Ning through his recent continuous pondering, drawing on the formation pattern on the silver scroll and the Hidden Spirit Array Plate.

Whether it is efficacy or scope, it must be above the array disk.

Standing in the magic circle, I closed my eyes and felt the effect, and the scorching fire spiritual power from before had been isolated.

Yan Ning nodded with satisfaction, and then re-looked at the 'Thunder Fire God Destroying Array' in front of him.

As expected, Yan Ning was not surprised.

Although the connection between the aura of the space here and the outside world was cut off, the light curtain formed by the 'Thunder and Fire God Destroying Array' did not weaken at all, but the fire aura on the light curtain became more and more abundant, highlighting the entire formation more obviously.

If you can cut off the supply of spiritual energy just by using this simple 'Hidden Spirit Array', then I'm sorry for the prestige of 'Thunder and Fire Exterminator'.

Yan Ning half-squinted, frowned, and carefully looked at the situation inside the formation through the light curtain.

At this moment, there was silence in the formation, and except for the closed door of the cave, there was no other abnormality. But he didn't dare to be careless at all, knowing very well how terrifying the consequences would be if there was any reckless move that caused the formation in front of him to be activated.

For the sake of today's plan, only by finding out the source of this formation and then finding a way to cut it off, can it be possible to completely break it.

And judging from the situation just now, this formation is obviously connected to the leylines here. The hot magma in the space is bottomless, and it is unrealistic for him to dive into it with his current cultivation, and it seems that he can only start from the outside.

Yan Ning simply sat on the spot, staring intently at the formation in front of him, while pinching his fingertips with one hand, doing calculations.

Two days later, Zhao Jinyun also returned from outside.

Seeing Yan Ning sitting cross-legged on the ground, still thinking about the method of breaking the formation, he didn't bother him, and observed the 'Thunder and Fire Extermination' array in front of him.

Just when Zhao Jinyun's eyes flickered and kept staring at Yan Ning, he saw that Yan Ning suddenly got up and took out a lot of materials from the storage bag, obviously having further plans.

So he asked happily, "How is the junior brother, but there is a way to crack it?"

Yan Ning nodded and replied, "I do have some preliminary ideas, but I still need to verify them further." Can you collect some 'igneous rock crystals' around this magma for me?"

Zhao Jinyun didn't allow anything, and immediately got up and collected a lot of 'igneous rock spars' on the side of the magma and handed them to Yan Ning.

These fire rock spars have evolved from absorbing the rich fire attribute aura here for many years, and they are also the dream of those who cultivate fire attribute spells. The energy contained in this type of spar is single and pure, and once it appears, it will be highly sought after and highly valuable.

After taking the 'Fire Rock Crystal', Yan Ning took out a delicate array plate that had already been refined from the storage bag, placed several red and hot crystals in the grooves on the array plate one by one, and then explained to Zhao Jinyun in detail what he was going to do next.

"Senior brother, the formation here is the energy absorbed through the leylines deep in the magma, and with our current ability, it is impossible to cut it off from the outside. Later, the junior disciple simulated the unique aura environment here through these 'fire rock crystals' on the array disk, and then sent the array disk into the large array through the bridging point of this formation. ”

After speaking, Yan Ning pointed to a place on the flame light curtain with his finger, and continued to explain in an orderly manner: "After this array enters it, it can echo with the junior disciple outside, and it should be able to barely open a gap without interfering with the big array. If what I expected, the eye of this large array should be under the stone gate in front. ”

"When the time comes, I will enter this large array through the gap, and then I will try to set up an array to try to draw out the spiritual source in the large array. When the spiritual source in the formation is exhausted, the formation will be self-defeating, even if there is still some power, with the cultivation of our senior brothers, it can be withstanded. ”

"It's just that this method will definitely take a long time, I don't know how many years this big array has existed, and the spiritual power in it must be very abundant, and it can't be completed in a short time. In addition, the formation is also inhaled when it is extracted, but it is much less than the aura extracted. ”

After finishing speaking, Yan Ning looked at Zhao Jinyun calmly, waiting for his decision.

After listening to Yan Ning's narration, Zhao Jinyun's expression was unbearable, and he sighed eagerly:

"Senior brother is really a genius! I am ashamed to be able to think of such an ingenious way to crack this formation! It is not a problem to spend some time, you and my brother have come out to practice, and there is a lot of time. It's a big deal, just retreat and practice here. ”

Then, he asked with concern: "It's just that junior brother, will it be too risky for you to enter this formation?" If it's too dangerous, let's not try." Think about other ways to be safer, no matter how bad it is, you can ask the master and his old man to help. ”

"After some calculations before, it is not too risky. This is also the most effective method that the junior disciple can think of at present. After all, I don't know how many months this formation has existed, and although it is powerful, there is always some loss in some places. The junior brother still has some confidence in this, even if there is an accident after entering, he can exit in time. Yan Ning's tone was quite confident, and Zhizhu was in his hand.

Seeing that Zhao Jinyun was also moved, he continued to advise: "It's just that once the junior brother enters this gap, there must be Senior Brother Lao to support him outside, and once there is any unstable situation outside, I also need the senior brother to notify me outside in time." ”

Zhao Jinyun saw that Yan Ning had made up his mind, and knew that it would be difficult to make him change his mind, unless he had a better idea. Besides, he has indeed coveted the things in this cave for a long time, and he didn't say anything more, and solemnly told him to be careful.

After the two agreed, they didn't say much.

Zhao Jinyun went out again to confirm the formation laid out outside, while Ning slowly held up the array in his hand and injected mana into it to urge.

Then, Yan Ning very cautiously slapped the array plate inlaid with 'Fire Rock Crystal' to the place he had pointed at just now on the light curtain.

Suddenly, the light curtain and the array disk flashed red at the same time!

The array disk that was still in Yan Ning's hand, after the light flashed, had already appeared in the large array inside.

Yan Ning nodded in satisfaction, it seemed that the situation seemed to be in line with what he had expected.

Then his hands continued to pinch, and the array disk in the large array shone with dazzling red light, and the light curtain in front of him suddenly appeared a small gap, and the entire light curtain kept shaking slightly. Since the Hidden Spirit Array here had already isolated the spiritual energy from the outside, the light curtain gradually flattened after a while, and the tiny crack did not close immediately under the illumination of the array.

After doing all this, Yan Ning did not rush in, but kept looking around.

After confirming that nothing was missing, he nodded to Zhao Jinyun, held two fire rock crystals in his hand, stretched out a fiery red shield, and cautiously touched into the large array.
