Chapter 892 Treasures of the Treasure House
bang, bang, bang...

In the blink of an eye, several flashes of spiritual light passed by, accompanied by slight cracking sounds. The emerald green light curtain covering the wooden shelf shattered one after another, revealing the treasured spiritual objects on the wooden shelf.

Without the cover of the emerald green light curtain, brilliant rays of light suddenly appeared.

On each layer of several wooden shelves, there are a considerable number of emerald green jade boxes. On the jade boxes, array ban inscriptions are faintly visible, all of which are filled with a strong sense of vitality.

Chu Mu rolled up his sleeves and took a jade box into his palm. Emerald green light surged, and the sense of vitality was even clearer.

“Spiritual Jade…”

Chu Mu raised his eyebrows, but soon, he seemed to have noticed something, and a suspicious look appeared on his face. His mind was fixed on the jade box, and he peeked into the mystery of the jade box.

"What an exquisite refining method!"

After a few breaths, Chu Mu exclaimed in praise.

The so-called soul-containing jade is ranked as the top three grade. Due to its unique soul-containing effect, in the world of immortal cultivation, it is often used as a container for elixirs, spiritual medicines, and other spiritual objects that are prone to spiritual loss.

However, the inherent value of the Soul-Enhancing Jade means that it is impossible for ordinary spiritual objects to use such precious Soul-Enhancing Jade to preserve them.

The most interesting thing is that the jade box in his hand does not seem to be just spiritual jade. It has obviously undergone special smelting, making its vitality more pure and rich. Its sealing effect as a presentation container is also obviously more perfect.

The spiritual jade that has undergone such special smelting is almost as good as some lower quality fourth-level spiritual objects.

And as far as he knew, the price to pay to smelt the third-grade top-grade soul-enhancing jade to the current level was not small!
It is easy to imagine how high-quality and rare the spiritual object is that can use such high-quality spiritual jade as a presentation container.

"Fifty-six soul-enriching jade boxes..."

Chu Mu looked at the jade boxes placed on the wooden shelves, and an exact number emerged in his mind.

He raised his hand and the seal on the jade box in his hand was opened. A biting cold air seeped out of the jade box and in a flash, it spread from his palm to his arm. Half of his arm was stained with frost.

"Ice Soul Cold Sword Grass."

Staring at the white grass with frost surging in the jade box, a lot of information about this Ice Soul Cold Mist Grass quickly emerged in his mind. Just a slight identification made Chu Mu's breathing quicken.

Bingpo Hanjian Grass grows in extremely cold and gloomy places, and fifty years is its maximum growth limit.

Every time a catastrophe occurs, a frost pattern appears on the grass leaves. After five hundred years, the leaves become sword-shaped, with frost stained around the edges, like a sword stained with frost.

After thousands of years, the grass leaves withered, and the sword was nourished by a leaf. The grass leaves turned into ice crystals. The sword body was three inches long, like a sharp sword reaching into the sky, and the frost on the sword tip turned into cold air surrounding it.

After a thousand years, a hundred years will be considered a catastrophe.

Every time a catastrophe is overcome, the growth limit is crossed and the sword body will grow one inch.

And the blade of the Ice Soul Cold Sword Grass in front of him... is eight inches long!

That is...it has been growing for one thousand five hundred years!

Of course, this time is not absolute.

Just like a cultivator, the time it takes to make progress in cultivation will inevitably vary.

For those with extraordinary talents, it is not impossible to form a pill in a hundred years.

Those with poor qualifications will find it difficult to pass the Qi training stage throughout their lifetime.

Those with abundant resources can make rapid progress in their practice, while those with scarce resources find it difficult to make progress.

Although the existence of spiritual plants is not as difficult to regulate as the cultivation of immortals, there are many factors that can affect their growth rate.

Just like the secret realm of spiritual plants in the Changsheng Sect, in that extremely perfect spiritual plant cultivation system, any spiritual plant has a perfect growth environment corresponding to its own growth conditions, and has various equally perfect growth aids.

In such a perfect environment, the growth rate of spiritual plants will naturally be greatly accelerated. The so-called growth years are more about the quality of the spiritual plants.

But no matter what, one thousand five hundred years must mean that the medicine is as old as one thousand five hundred years, and there is no falsehood at all.

According to the immortal cultivation world's classification of the grades of elixirs, those under a hundred years old, with a limit of thirty years, are divided into upper, middle and lower grades as the first grade, and those between a hundred and three hundred years old, with a limit of a hundred years, are divided into upper, middle and lower grades as the second grade.

From three hundred to nine hundred years, with a limit of two hundred years, it is divided into three grades, upper, middle and lower.

After nine hundred years, it reaches the fourth level.

It is limited to three hundred years and is divided into upper, middle and lower grades.

According to this classification, this 1,500-year-old Ice Soul Cold Sword Grass has undoubtedly reached the limit of a fourth-grade mid-grade spiritual medicine, and can even be barely said to be a fourth-grade high-grade spiritual medicine.

Chu Mu raised his hand again and held another soul jade box in his hand. The seal was lifted, and this time, a heat completely different from the frost came.

The heat is rolling, scorching hot.

A red magical medicine that looked like tangled tree roots also appeared.

It is as red as jade, crystal clear, and looks like a root carving of the elixir, but it seems more like it is carved from beautiful red jade.

"Akagen, more than 1,100 years..."

Chu Mu's arm trembled slightly, and the heat in his eyes suddenly intensified, but soon, he forcibly suppressed this heat.

Looking at the other jade boxes, as they were opened one after another, Chu Mu knew them all like the back of his hand, murmuring the names of the elixirs one after another.

What followed was the appearance of spiritual herbs that were over a thousand years old.

Chu Mu was very careful and meticulous. He examined and observed each spiritual medicine again and again. Afterwards, he carefully restored the seal of the Soul-Yinning Jade Box to prevent the medicinal effects from conflicting with each other and damaging these thousand-year-old spiritual medicines that were considered treasures of the world.

It took Chu Mu nearly an hour to examine the fifty-six jade boxes one by one.

After returning each jade box to the wooden shelf and sealing them temporarily, Chu Mu looked at the wooden boxes piled up in both corners.

Just like this jade box that stores the elixir, the material of the jade box alone is extremely extraordinary, and the material of the wooden box is equally outstanding.

The spiritual wood is a well-known third-level forbidden spiritual wood in the world of immortal cultivation. The texture of this spiritual wood is hard, and its mystery lies in its forbidden nature.

Using this spiritual wood to make a container can perfectly block the erosion of external spiritual energy, and can also prevent the objects placed in it from leaking out their aura and causing damage to the spiritual energy.

At the same time, this spiritual wood also has some natural spatial properties, which can be used to create storage space. Although it is difficult to be used as the main material for portable storage devices, it is undoubtedly a perfect fit as a fixed storage device. Of course, this is also one of the uses of this spiritual wood. The greatest use of this spiritual wood is as a "building material".

The effect of the ban, whether it is the monks' caves, houses, city construction, or flying boats...

They can all be said to be mysteries that must exist.

This is also the fundamental reason why this spiritual tree is famous in the world of immortal cultivation.

However, since the spiritual wood is of the highest grade of the third level, those who can use it are naturally not ordinary things.

Chu Mu looked around and found that compared to the number of jade boxes, the number of wooden boxes was much greater.

In this huge cave space, there are hundreds of wooden boxes of various sizes.

Each one of them exudes the aura of space, and it is obvious that there is something mysterious inside.

"Frost Water, Nine-Refined Black Iron, Scarlet Flame Dragon Stone..."

As his spiritual sense perceived, the names of spiritual objects were taken into account one by one. Chu Mu took a step forward and came to a wooden box. He raised his hand and the restriction of the wooden box dissipated. His spiritual sense probed into it and found that there was something mysterious inside.

And inside it, there is a brilliant aura.

As he sensed it, he realized that this brilliant spiritual light came from the neatly stacked high-quality spirit stones.

The entire storage space of the wooden box is filled with high-quality water-attributed spirit stones.

Chu Mu looked at the other wooden boxes again. The dozens of wooden boxes in this corner were all filled with top-grade spirit stones of various attributes.

On top of these dozens of wooden boxes of spirit stones, there is a wooden box about one foot in size.

The wooden box array was dim, but it was not caused by him.

Chu Mu frowned slightly, raised his hand, and the strange wooden box was in his palm.

The wooden box formation had obviously been dim for some time. Without the partition and seal of the formation, the space within it could be clearly perceived.

Chu Mu was surprised. He brushed his fingertips across the wooden box and opened it. Inside was not a storage space, but just a simple wooden box. The lingering spatial aura was just the contamination of the spatial aura of the surrounding wooden boxes.

And inside the wooden box, it was... empty.

Chu Mu raised his eyebrows and looked up at the top of the cave. After pondering for a while, he raised his hand and the void rippled, and the image flickered.

The screen shows him standing there in real time.

As his mind moved, the remaining image seemed to go back in time and flashed rapidly, revealing all the changes that had taken place in this treasure house.

In just a few breaths, or a few months of retrospection, the picture suddenly froze.

It is exactly where he is standing now, and there is this wooden box.

This person is undoubtedly the Yuanying Taishang who once sat in Yanyun and dominated Yanyun for 800 years.

The leader of the Tianfu lineage, whose cultivation level is in the middle stage of the Nascent Soul, his name is... Hong Yu!
If he remembered correctly, in that secret world, the master of the Tianfu Vein had also turned into a demon.

Moreover, after the collapse of the secret realm, this leader of the Tianfu Vein also escaped from the pursuit of the Changsheng Sect Leader and disappeared in the turbulence of space.

"Three months ago..."

Looking at this frozen picture, Chu Mu seemed to be thinking about something.

According to the time calculation, three months ago, the one-year deadline of the conscription order was about to expire.

As far as he knew, the time when the master of the Tianfu Pulse arrived at the Changsheng Sect was around this time.

In other words, it was the eve of the leader of the Tianfu Pulse rushing to the Changsheng Sect.

A demon who had evolved into me, on the eve of rushing to the gate of Changsheng Mountain, came to this Chengyun Treasure House and took away the treasures stored in this wooden box...

Chu Mu’s eyes became brighter!

The inner core of the demon lies in the demonic body evolved from the sky, and its cultivation system must also be based on the devil!

This means that for a demon, immortal treasures should not be of much use.

Unless, you are purified by the true devil's energy and transformed into a monster...

But the problem is that the price to pay for this kind of refinement must be extremely high.

Of course, if you are in the demon world and mobilize the power of the demon world, that is another matter.

After all, the world of immortals is not the world of demons, and the rules of heaven and earth have nothing to do with the existence of demons. They are even incompatible like water and fire!

But it seems that it is not difficult to see the importance of this thing.

Otherwise, the leader of the Tianfu Vein, who had turned into a demon, would not have taken it away before leaving.

Chu Mu looked up, and as his mind moved, the frozen image began to flow again, recalling the previous surveillance footage.

When it is frozen again, several decades have passed.

In the picture, this time, a wooden box appeared.

However, the wooden box was not sent by the leader of the Tianfu Vein, but by a sect disciple stationed outside the treasury.

Judging from the boy's appearance and facial features in the picture, this boy is Hong Yu's eldest son, Hong Tianfeng.

When the wooden box was placed in the treasury, the boy came out of the treasury. The scene flowed, and in just a few days, Hong Yu hurriedly walked into the treasury and appeared directly in front of the wooden box.

Watching this scene, Chu Mu's expression suddenly became serious. He watched Hong Yu take down the wooden box and open the seal. Finally, the contents of the wooden box also appeared...
