The scene seems to be reappearing.

The sea of fire magma, the reconnaissance is gone.

Chu Mu stood outside the broken array, waiting with a little apprehension.

It didn't take long for several dragonfly spirit weapons to pass through the forbidden gap and return with the surging fire.

He raised his hand and waved, and several projections also appeared.

The function of the bamboo dragonfly at the spirit weapon level is naturally a leap improvement compared to the past.

This is true whether it is the scope of the investigation, the effectiveness of the investigation, or the defense itself.

The picture is very clear, entering the large array and being incomplete, what emerges is still a sea of fire magma, which is so rich that the fire is surging.

The deeper you go, the more intense it becomes.

Even, the magma is slowly approaching solidification, and the fire gas is almost physically attached to the magma.

In the end, the magma had completely solidified, and it had turned into stone, but under the action of the rich fire, this stone was washed into a golden texture.

In the big array, it seems that ...... Is it a fire vein mine?

Chu Mu carefully identified this fire vein mine, and for a moment, as if he had thought of something, his pupils shrank, and he seemed to understand a little.

He remembered that it was said that in the Great Chu Immortal Cultivation Realm, such as the Immortal Sect, there were countless spiritual veins occupied, but the spiritual veins used by Fang City as a real stronghold only occupied a part of them.

The remaining part of the spiritual veins are directly sealed.

The so-called sealing is to ban the spiritual veins with a formation ban.

The spiritual vein, on the other hand, will constantly produce aura.

Therefore, the aura is naturally also banned, so over time, the aura in it is naturally extremely rich, and when time evolves, the aura evolves into substance, and it will form a man-made spirit stone vein.

Even, under the feedback of such a rich aura, the growth of the spiritual veins will be accelerated a lot.

It is rumored that in the past, in order to prepare for the promotion of the spiritual vein to the third order, the spiritual vein of the Jade Emperor Valley was banned, and only a small part of the spiritual energy generated by the spiritual vein was fixedly released.

And in front of ......

It is also a spiritual vein, a rare fire attribute spiritual vein!

After a long period of banning, in the spiritual veins, there have been fire attribute spirit stone mines.

And...... It seems that there are not only spirit veins, but also spirit stone mines.

After a long period of fire-attribute spiritual energy, the mountain and stone deposits in it seem to have changed their nature and become spiritual mines in the true sense!

Chu Mu pursed his lips, rolled up his sleeves, put the dragonfly spirit weapon into the storage ring, and stepped out, and the whole person directly disappeared into this incomplete array.

Inside the array, outside the array, it's like two worlds.

Outside the large array, the earth fire magma surged, and although the fire qi was much calmer due to the presence of the earth fire spirit, it was not difficult to detect the irritability in it.

And in this large array, it is a fire attribute aura that is rich to almost liquid, pure and stable.

Compared with the thinner aura of the outside world, within this large array, just like the secret realm of the East Lake, the aura is so rich that it is terrifying!

After a little sense, he took a step forward and looked inside.

Just like the picture of the bamboo dragonfly's reconnaissance, the evolution of the long years, in the big array, everything has been spiritualized!

Spirit stones, spirit ores, and even ordinary soil have all become fire-attribute spiritual soil.

The scope of the large array is extremely large, and under the influence of the spirit ore spirit stone that has been spiritualized and substantial, the scope of divine sense detection is also greatly limited.

With a wave of his sleeves, four wolf puppets threw out, his heart moved slightly, and the wolf puppets roared, waved their claws, and plundered and excavated in this mine.

He was still cautiously scouting inside.

In this immortal cultivation world, just like the history of thousands of years in previous lives, every period has characteristics that belong to that period.

The characteristics of past lives are reflected in the aspects of clothing, language, writing, and etiquette.

In the world of cultivating immortals, this characteristic is reflected in the system of cultivating immortals.

For example, cultivating immortals and hundred arts, such as practicing exercises.

The evolution of a civilization of cultivating immortals is vividly reflected in the knowledge system of this civilization.

For example, the alchemy technique he mastered was obtained from the general outline of refining in the Immortal Dao Sect, and the alchemy technique of the current Great Chu Cultivation Immortal Realm, perhaps there has been no qualitative change in the overall knowledge structure, but the trivial aspects of the overall evolution have undergone earth-shaking changes.

Looking at this great array, from these side details, it seems that you can also perceive the age of this great array.

As far as he knew, the Immortal Sect was established in Dachu for nearly 20,000 years.

Twenty thousand years ago, legend has it that a sect of the Tiannan Sect ruled the present-day Great Chu, even including the northern grasslands and part of the southwest.

The Tiannan Sect fell apart, and the appearance of the Immortal Sect is said to have been formed by the union of several top families of the Tiannan Sect.

And these top families......

It is the five famous families at present.

What exactly happened in it, Chu Mu obviously didn't know.

But the age of this great array......

Chu Mu estimated that it could at least be traced back to that long era.

And this spiritual vein ......

Chu Mu also looked at it carefully.

He didn't know much about the spiritual veins either.

According to the rumored definition of the Great Chu Immortal Cultivation Realm, the spiritual veins are created by heaven and earth, and they are not immutable.

Spiritual veins can grow, and they can also be born under the creation of heaven and earth.

The spiritual veins are divided into surface spiritual veins and underground spiritual veins.

The so-called surface spiritual vein, in fact, there is no clear definition, some say that within a hundred zhang underground, it is considered a surface spiritual vein, and some say that it is within two thousand meters underground.

The definition is not clear, but there is one thing that is clear.

That is, the spiritual veins that immortal cultivators can use are all surface spiritual veins.

And this, obviously, involves a cost issue.

For example, in the surface mountain range, it is undoubtedly very simple for an immortal cultivator to use the spirit vein.

If it is tens of thousands of meters deep underground, the immortal cultivator wants to control the spiritual vein aura and establish a gathering place around the spiritual vein, and the difficulty is obviously not at the same level.

After all, immortal cultivators are desperate for the spiritual veins! What is particular about controlling the aura generated by the spiritual veins from the source, so as to surround these controllable spiritual energies for their own benefit.

In this immortal cultivation world, outside the Fang City, between the vast heaven and earth, the aura is getting thinner and thinner, and the influence of the desperate strategy in this aspect is obviously one of the reasons.

And this spiritual vein is obviously an underground spiritual vein.

He jumped from the outpost camp into the sea of fire magma, and by this time, to say the least, he had more than half a day.

For such a long time, even if there is a delay on the way, even if it goes around for a while, it is at least two or three hundred miles away from the ground.

Such a distance, coupled with the cover of the large array, and the cover of this infinite sea of fire magma, is estimated to be the fundamental reason why this spiritual vein has not been discovered.

"Third-Order ......"

Turning around, a rough guess also appeared in Chu Mu's mind.

This spiritual vein, the lowest is the third order!

As a result, he was breathing a little heavily.

A spiritual vein that has been sealed for tens of thousands of years, if it is not patronized by people on the way, how many rare things will be born in such a long time?

He couldn't suppress his excitement, and at this time, the movement of the blue wolf puppet also followed the connection of the divine consciousness imprint.

Chu Mu jumped to the bottom of a red-golden mountain peak, and walked hundreds of meters along the passage opened by the blue wolf puppet.

The blue wolf puppet had stopped ravaging, and in front of it, a crystal clear fiery red clearly came into view.

"Fire Attribute Spirit Stone Mine!"

Almost at a glance, Chu Mu recognized it.

He looked around, the four blue wolves had already excavated the low-level spirit ore in the surrounding area, and only this stretch of fiery red spirit stone vein, like a giant dragon, lay in the belly of the mountain.

He swallowed, and his breathing was a little rapid and difficult.

"Open the mine!"

He couldn't wait to give the order, but then, as if sensing something, his expression changed slightly, and he shouted, "Stop! ”

At the sound of an order, the four blue wolf puppets that had just raised their claws and were about to mine also stopped neatly.

Chu Mu looked suspicious, and cautiously stepped forward, his fingertips lightly brushed over the spirit stone veins in front of him, and the touch came into his heart, and the scene of divine perception also poured into his mind.

He took a deep breath, slowly got up, and looked at the fiery red and crystal spirit stone vein again.

"Go dig over there, you go over there!"

He spoke in a hurried tone and ordered again.

Several blue wolf puppets moved when they heard the sound, and according to Chu Mu's instructions, they dug in all directions.

It was just a change of direction in the excavation, but in a moment, what caught Chu Mu's eyes was a completely different scene from before.

"Big, big......"

Chu Mu muttered to himself, his eyebrows full of shock.

The role of the outside world array is to ban.

And inside, there is a big array!

And this big array is not a forbidden combination in the traditional sense, but a big array formed with the help of natural terrain!

With the entire spiritual vein as the foundation, connecting the earth's veins and fire, and then using the external great array as the ban, with this natural great array as the core, just to nourish the ...... This spirit stone vein in front of you!

Chu Mu became more and more suspicious, such a big spend, just for a spirit stone vein?

When these words are spoken, the ghosts don't believe them!

The only explanation is that there is something terrible in this spirit stone mine, which requires a huge amount of fire attribute spiritual energy to be nourished, or even offered!

Therefore, in the years far ago, there was a certain immortal cultivator who arranged such a chain of large arrays until now.

Suddenly, Chu Mu recalled the incomplete large array he had just seen, that gap, could it be that the cultivation was completed, and the ancient monk had taken away the cultivation things?

Or, in the past, who broke in?

He silently guessed, and at the same time, he also ordered the blue wolf puppet to continue digging around this spirit stone vein.

And he himself also walked around this spirit stone mine, observing the operation of this semi-natural array, so as to analyze where the real core was in this huge spirit stone vein!

As for directly destroying this spirit stone vein, Chu Mu obviously didn't dare to bet, after all, the way of the formation was interlocking, and one link was wrong, and that was the chain reaction.

He also didn't know how the real core, the nourishing thing he guessed, would be after a long period of time......
