Longevity starts with learning

An hour later.

Chu Mu stopped at the side of this fiery red and crystal spiritual stone vein.

The crystal red in front of him, to the naked eye, is not much different from other places.

But in the perception of the divine sense, this piece of crystal red in front of him is a little inconsistent with this semi-natural formation.

How can a natural formation be inconsistent?

Chu Mu touched his chin and was slightly thoughtful.

Fire attribute spiritual veins, fire attribute spiritual ore, and it is still in this sea of ​​fire magma. The land veins are surging with fire.

Everything is inseparable from fire.

This is equivalent to artificially constructing a special fire attribute environment, and then using this special fire attribute environment to achieve some unknown purpose.

This is undoubtedly easy to understand. In the world of cultivating immortals, there are too many spiritual objects, all of which are produced by various coincidences.

For example, the two skills of spiritual plant master and spiritual mine master are created to study such coincidences.

They also use various methods to simulate an environment suitable for the transformation or growth of spiritual objects.

Summarizing the rules and experimenting with the rules, slowly, these two systems have been formed.

Of course, these spiritual objects that require special environments and coincidences to be born are often extremely rare.

And this kind of big hand in front of him...

Chu Mu hesitated for a moment, then he raised his hand and pinched the formula, and threw out a series of array prohibitions, which fell on the fiery red crystal in front of him.

The array prohibitions merged with the array prohibitions, and as time passed, the fiery red crystal in front of him slowly melted.

About half an hour later, the natural spiritual stone vein in front of him actually emerged with a deep hole that was one person high and about a meter wide.

The fiery red crystal from inside to outside, a fiery red tunnel immersed in the spiritual stone vein, has already taken shape.

Chu Mu waved his hand, and a dragonfly spiritual weapon sank into the pit of the mine. Soon, the dragonfly spiritual weapon flew back, and a scene appeared.

After a moment, he rolled up his sleeves, put away the dragonfly spirit weapon, stepped out, and stepped into the fiery red and crystal passage.

According to the picture just detected, the passage is very long, and it seems to extend all the way to the center of the fire attribute spirit stone vein.

The passage is in the spirit stone vein, and the fire attribute spirit energy is almost liquid. The spiritual sense detection is undoubtedly compressed to the extreme, and can only cover a few meters around the body.

Chu Mu walked forward cautiously, his body tense and extremely vigilant.

Fortunately, this passage does not seem to have any danger. Although he was vigilant, he also arrived at the end of the passage very smoothly.

A gray-white stone door embedded in the vein also caught Chu Mu's eyes.

He stood in front of the door. In his spiritual sense, there was no restriction on the stone door. It seemed that it was really just a door.

But at this time, his heart couldn't help but be a little nervous. The traces of human intervention were very clear.

Such a big move is obviously impossible for a foundation-building cultivator to do.

It must be above the foundation building stage, a Jindan Zhenren, or even the legendary Yuanying old monster.

Such an existence, the means are beyond his imagination.

Although it seems that tens of thousands of years have passed, who knows if there are any back-up plans left.

Chu Mu was entangled for a while, and finally made up his mind. He stretched out his hand to touch the stone door, and the power surged. The next second, the stone door that had been closed for who knows how many years was slowly pushed open.

What came into view was still a crystal clear fiery red.

In the crystal red, there was a cave similar to a natural cave. The cave was not big, only a few feet in radius.

The scenery of the cave was also extremely simple.

A fiery red platform similar to a sacrifice was located in the center of the cave. On the platform, there seemed to be a raging flame.

Apart from this, there was nothing else in the cave.

Chu Mu frowned, and he used a puppet to test it. After confirming that there was no abnormality, he walked into the cave.

After walking around the platform and confirming that there were no other abnormalities in the cave, Chu Mu looked at the platform in front of him.

The platform was nearly two meters high and formed a pyramid shape, with steps on all four sides leading to the top.

The texture of the platform...

Chu Mu pursed his lips, and was somewhat accustomed to the arrogance of the ancient cultivators.

This platform was actually built with medium-grade fire-attributed spirit stones.

And in the perception of the divine sense, the core and source of everything was just this platform.

The surging energy gathered on this platform, and the endless spiritual energy washed over it. Under such a day-to-day effect, the spirit stone platform in front of him had obviously been completely integrated, and even exceeded the limit of medium-grade spirit stones.

Chu Mu looked up at the top of the platform, and then stepped onto the steps, step by step, onto the platform.

What caught his eye was actually a pill furnace as tall as a person.

Chu Mu was slightly startled. He had imagined many scenes, such as magic weapons, spiritual materials, and even spiritual medicines that had been tempered for thousands of years, but he never thought that such a big battle was for alchemy?

This alchemy... is it the alchemy he learned?

After a long time, the earth fire roasted day after day, and the nature of the alchemy furnace in front of him had obviously changed.

Under the perception of the divine sense, there was only a strong accumulation of fire. From the perspective of an alchemist, this alchemy furnace is no longer suitable for refining any other elixir except fire-attributed elixir.

It has nothing to do with the level of the alchemist, but the nature of the alchemy furnace itself has completely changed.

"Huh?"

Chu Mu suddenly stopped behind the alchemy furnace.

The alchemy furnace, which was as high as a person, just blocked the view behind it.

At this time, he noticed that there was a... corpse behind the alchemy furnace?

Chu Mu took a step back and fixed his gaze on the corpse in front of him.

The corpse was well preserved, but it was obviously corroded by the fire of these long years, turning it into a jade corpse that was as red as jade!

Vaguely, one can also see the original appearance of the corpse, which should be that of a graceful female nun.

Divine consciousness covered it, and the vague remaining aura that was far more terrifying than the foundation clearly proved that this woman must be a high-level monk above the foundation.

There was a large hole in the woman's abdomen, which seemed to have pierced her entire body.

On the jade corpse, one could clearly see its shriveled internal organs. It was obvious that he had been severely injured in front of his body.

But why... died here?

Chu Mu thought silently, and a line of speculation also emerged in his mind.

The person behind the mystery of this place is this woman.

Then, the woman fought with others, was seriously injured, and fled here...

Therefore, the formation is incomplete?

Then what is this woman practicing in such a big battle...?

Chu Mu slowly squatted down. The woman's robes had been completely burned away. There was no foreign object visible on the jade body. Only a pale silver ring remained on her index finger.

Chu Mu carefully touched the woman's body and after confirming that there was nothing abnormal, he took off the ring.

The divine sense touched it without any obstruction, and the divine sense penetrated into the ring, and what came into perception was a broken storage space.

Most of the space has collapsed, and only a little space power is left to maintain the existence of the remaining storage space.

But such an existence is obviously in danger, and it seems that it will completely collapse and be destroyed at any time.

Before he had time to look further, his consciousness moved slightly, and the few items in the remaining storage space were all separated from the storage space and suspended in front of him.

But at this moment, something like this movement completely broke the fragile balance of this broken storage space. In the dark, I only felt a weak power of space flashing. The ring in my hand was still a little bit... The pale silver that is bright becomes completely dim.

When I looked again with my consciousness, I found that the ring had become a dead object.

He looked at several items suspended in front of him.

Two jade slips, one jade vase, and one jade box.

Apart from that, there is nothing else.

Chu Mu inspected them one by one. The two jade slips were both alchemy books, recording several elixir recipes and some experience in alchemy techniques.

The jade bottle contains several pills. Thanks to the good sealing effect of the jade bottle, the potency of the pills is still intact. Judging from its potency, it seems to be some kind of healing pill, and it should be among the best. Level three.

In the jade box, there is an elixir. The elixir is Stone Forest Ginseng. It is about six hundred years old and is extremely rare.

Obviously, the information about such a large battle has either disappeared into the turbulence of space, or has gone with the fall of this woman.

Chu Mu looked at the flaming red alchemy furnace in front of him and pondered for a moment. He also sat cross-legged, raised his hands to make secrets, and threw out a series of magic formulas, which finally landed on the alchemy furnace.

He wants to open the furnace to get the elixir!

But when he tried to control this alchemy furnace, he keenly discovered something unusual.

This alchemy furnace has been refined for tens of thousands of years by such a large formation. According to common sense, it must not have any other attributes except the fire attribute, and it must be extremely pure.

But at this time, he actually felt a bit of... the aura of thunder attribute on this alchemy furnace?

Chu Mu looked suspicious, and took a closer look. He thought that the lines on the surface of the alchemy furnace were made by refining. Looking at it now, he looked like traces left by lightning. However, after long years of burning, After being roasted, it slowly... becomes natural.

At this time, he also suddenly remembered the incompleteness of the external formation...

Perhaps, the incompleteness of the formation was not caused by this woman, but by...

Thunder? Heavenly catastrophe?

Chu Mu's pupils shrank, guessing from this, his heart was almost uncontrollably beating violently.

He remembered that when he was in Shuitianfang, he had borrowed some books from the Contribution Hall, and in one of the jade slips, he saw a description of the Heavenly Tribulation.

It is said that after the immortal cultivator builds the foundation, whether it is the elixir or the Nascent Soul, there will be a disaster from heaven.

Only by passing the test of heavenly tribulation can one be truly promoted.

The same is true for monsters. In fact, the catastrophe of monsters is said to be much more terrifying than the catastrophe of immortal cultivators.

All in all, heavenly tribulation is a test for practitioners who go against heaven!

And this kind of test does not only exist on living things, but also on dead things.

Dead objects such as elixirs and magic weapons also have heavenly tribulations, called elixir tribulations and weapon tribulations.

However, according to the description in that jade slip, calamities such as pill calamity and weapon calamity are extremely rare.

Every time it appears, it means that something "Jealous" must appear.

Heavenly jealousy... although it is just a description.

But how terrifying would it be if a pill or a magic weapon could make God jealous and bring disaster specifically for this purpose?

Chu Mu stared blankly at the alchemy furnace in front of him, and an associative scene had already appeared in his mind.

Such a large battle has been refining the elixir for many years. On the day the elixir was completed, the woman arrived with her seriously injured body.

A catastrophe fell from the sky, penetrated tens of thousands of meters of the ground, ignored the sea of ​​fire and magma, broke through the seal of the formation, and struck directly on the alchemy furnace.

In this way, the great formation was incomplete and the Earth Fire Spirit was born.

But why did this woman die?

Can the Pill of the Alchemy Furnace survive the disaster or not? Does it still exist?
