Longevity starts with learning

The scene seemed to be replaying.

Fire and lava, the investigation is over.

Chu Mu stood outside the broken formation, waiting slightly uneasily.

Not long after, several dragonfly spiritual weapons passed through the gap in the formation and returned with the surging fire.

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

The functions of the bamboo dragonfly at the spiritual weapon level have naturally improved dramatically compared to before.

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

The picture is very clear, the formation is incomplete, and what emerges is still the sea of ​​fire and magma, with extremely rich fire energy surging.

The deeper you go, the richer it becomes.

In fact, the magma is slowly approaching solidification, and the fire is almost physically attached to the magma.

In the end, the magma had completely solidified and originally turned into stone. However, under the influence of the strong fire energy, this stone was washed away into a golden texture.

In the big formation, it seems... it's a fire vein mine?

Chu Mu carefully identified the fire vein mine. For a moment, he seemed to think of something. His pupils narrowed slightly, and he seemed to understand something.

He remembered that it was said that in the world of Dachu Immortal Cultivation, such as the Changsheng Sect, they occupied countless spiritual veins, but the actual spiritual veins used by Fangshi as a stronghold only occupied a part of them.

The rest of the spiritual veins are directly sealed.

The so-called sealing means to seal the spiritual veins with the formation.

But the spiritual veins will continuously produce spiritual energy.

Therefore, the spiritual energy is naturally sealed in it. Over time, the spiritual energy in it is naturally extremely rich. When time evolves and the spiritual energy evolves into substance, artificial veins of spiritual stone will be formed.

In fact, under the feedback of such rich spiritual energy, the growth of spiritual veins will be accelerated a lot.

It is said that in the past, in order to prepare for the promotion of the spiritual veins to the third level, the Jade Emperor Valley had sealed the spiritual veins of the Jade Emperor Valley and only released a small part of the spiritual energy generated by the spiritual veins.

And in front of me...

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

After the long years of confinement, fire-attributed spiritual stone mines have been produced in the spiritual veins.

And...it seems that there are more than just spiritual veins and spiritual stone mines.

After long years of fire-attribute spiritual energy washing away, the mountain stone mineral deposits in it seem to have changed their nature, becoming true spiritual mines!

Chu Mu pursed his lips, rolled up his sleeves, put the dragonfly spiritual weapon into the storage ring, and with one step, he was directly submerged into the incomplete formation.

Inside the formation and outside the formation, they are like two worlds.

Outside the formation, the earth fire magma was surging. Although the fire was much calmer due to the presence of the earth fire spirit, it was not difficult to detect the irritability within it.

And within this formation, there is fire-attribute spiritual energy that is so rich that it is almost liquid, pure and stable.

Compared with the thin spiritual energy in the outside world, the spiritual energy within this formation is as frighteningly rich as the East Lake Secret Realm!

After sensing it for a moment, he took steps forward to check it out.

Just like the scene of the bamboo dragonfly investigation, after long years of evolution, everything in the great formation has become spiritual!

Spirit stones, spirit mines, and even ordinary soil have become fire attribute spiritual soil.

The area covered by the formation is extremely large, and under the influence of the spiritual minerals and spiritual stones that have been spiritualized and substantive, the scope of divine consciousness detection is also greatly restricted.

He waved his sleeves, and the four wolf puppets were thrown out. With a slight thought in his mind, the wolf puppets roared, swung their sharp claws, and began to plunder and dig through the mines.

He was still carefully investigating it.

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

The characteristics of the previous life are reflected in clothing, language, writing, and etiquette.

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

For example, practicing immortality and various arts, such as practicing martial arts.

The evolution of a civilization that cultivates immortality is vividly reflected in the knowledge system of this civilization.

For example, the weapon refining technique he mastered, which was obtained from the general outline of weapon refining of the Immortal Dao Sect, and the weapon refining technique in the Dachu Immortal World today may have no qualitative changes in the overall knowledge structure, but the side effects of the overall evolution , but earth-shaking changes have taken place.

Looking at this formation, from these details, one can seem to sense the age of this formation.

As far as he knew, the Changsheng Sect had been established in Dachu for nearly 20,000 years.

Twenty thousand years ago, it was said that a sect named Tiannan Sect ruled the present-day Chu State, even including the northern grasslands and part of the southwest.

The Tiannan Sect fell apart, and the emergence of the Changsheng Sect was said to be the result of the union of several top families of the Tiannan Sect.

And these top families...

Then there are the five famous families in Dachu.

Chu Mu obviously didn't know what happened.

But the age of this formation...

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

And this spiritual vein...

Chu Mu also looked carefully and felt.

He didn't know much about spiritual veins either.

According to the rumored definition in Da Chu's immortal world, spiritual veins are created by heaven and earth and are not static.

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

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

There is actually no clear definition of the so-called surface spiritual veins. Some say that those within a hundred feet underground are considered surface spiritual veins, while others say that those within two kilometers underground are considered surface spiritual veins.

Although the definition is not clear, one thing is very clear.

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

And this obviously involves a cost issue.

For example, if it is in the surface mountains, it is undoubtedly very simple for cultivators to use spiritual veins.

If it is tens of thousands of meters deep underground, cultivators want to control the spiritual energy of the spiritual veins and build a place for the market to gather around the spiritual veins. The difficulty is obviously not at the same level.

After all, cultivators use the strategy of extinction for spiritual veins! The emphasis is on controlling the spiritual energy generated by the spiritual veins from the source, so as to make profits for themselves around these controllable spiritual energy.

In this world of cultivation, outside the market, between the vast heaven and earth, the increasingly thin spiritual energy, the influence of the strategy of extinction in this regard is obviously one of the reasons.

And this spiritual vein is obviously the underground spiritual vein.

He jumped into the sea of ​​fire and magma from the outpost camp, and it has been at least half a day since then.

Even if he was delayed in the middle and wandered around for a long time, he was at least two or three hundred miles away from the ground.

Such a distance, coupled with the cover of the formation and the endless sea of ​​fire and magma, is probably the fundamental reason why this spiritual vein has not been discovered.

"Level three..."

After walking around, a rough guess also emerged in Chu Mu's mind.

This spiritual vein is at least level three!

When he came to the conclusion, his breathing became a little rapid.

If a spiritual vein that has been sealed for tens of thousands of years has not been visited by anyone in the middle, how many rare things will be born in such a long time?

He could not suppress his excitement, and at this time, the movement of the Canglang puppet also came along the connection of the divine consciousness imprint.

Chu Mu jumped to the bottom of a red-gold mountain, and walked hundreds of meters along the passage opened by the Canglang puppet.

The wolf puppet had stopped plundering, and in front of it, a crystal clear fiery red was clearly visible.

"Fire attribute spirit stone mine!"

Chu Mu recognized it with just one glance.

He looked around, and the four wolf puppets had dug up all the low-level spirit mines in the surrounding area, leaving only this long fiery red spirit stone vein, like a giant dragon, lying in the belly of the mountain.

He swallowed his saliva, and his breathing became a little rapid and difficult.

"Open the mine!"

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

At the command, the four wolf puppets that had just raised their claws to mine also stopped in unison.

Chu Mu looked suspicious, and walked forward carefully, his fingertips gently swiped across the spirit stone vein in front of him, the touch reflected in his heart, and the scene perceived by his consciousness also flooded into his mind.

He took a deep breath, slowly stood up, and looked at the fiery red and crystal-clear spiritual stone vein.

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

He gave the order again in a hurried tone.

Several gray wolf puppets moved upon hearing the sound, and dug in all directions according to Chu Mu's instructions.

It was just a change of digging direction, but in just a moment, what Chu Mu saw was a completely different scene from before.

"Big hand, big hand..."

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

The function of the external formation is to seal.

And there is another formation inside!

And this formation is not a combination of formations and bans in the traditional sense, but a formation formed by the natural terrain!

With the entire spiritual vein as the foundation, connected to the earth vein fire, and then with the external formation as the ban, with this natural formation as the core, just to nourish... this spiritual stone vein in front of him!

Chu Mu was more and more surprised. Such a big hand, just for a spiritual stone vein?

No one would believe this if I said it out loud!

The only explanation is that there is something extraordinary in this spiritual stone mine that requires a huge amount of fire attribute spiritual energy to nourish, or even provide for!

Therefore, in the distant past, a certain immortal cultivator had arranged such a chain formation until now.

Suddenly, Chu Mu recalled the incomplete formation he had just seen. Was that gap the completion of the nourishment, and the ancient cultivator had taken away the nourishing things?

Or, in the past, someone broke in?

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

And he himself also wandered around this spiritual stone mine, observing the operation of this semi-natural formation, and thus analyzing where the real core is in this huge spiritual stone vein!

As for directly destroying this spiritual stone vein, Chu Mu obviously didn't dare to gamble. After all, the way of formation is linked together. If one link is wrong, it will be a chain reaction.

He also didn't know what the real core, the nourishing thing he guessed, would be like after so many years...

...
