Longevity starts with learning

Bang, bang, bang...

In the blink of an eye, several spiritual lights flashed through, followed by subtle cracking sounds. On the wooden frame, the emerald green light curtain broke one after another, revealing the spiritual objects treasured on the wooden frame.

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

On several wooden shelves, on each floor, there are a considerable number of emerald green jade boxes. On the jade boxes, the formation forbidden inscriptions are looming, and they are all filled with a strong sense of vitality.

Chu Mu's sleeves were rolled up, and a jade box was placed in the palm of his hand. Emerald green light surged, and the sense of vitality became even clearer.

"Yun Ling Jade..."

Chu Mu raised his eyebrows, but soon, he seemed to notice something, his face showed suspicion, and his consciousness was fixed on the jade box, peering into the mystery of the jade box.

"What an exquisite refining method!"

After a few breaths, Chu Mu admired.

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

However, the inherent value of Yunling Jade is destined to prevent ordinary spiritual objects from being preserved by such precious Yunling Jade.

The most interesting thing is that the jade box in his hand does not seem to be just pure spiritual jade. It has obviously been specially smelted to make its vitality more pure and rich. It also has obvious sealing effect as a presentation container. More perfect.

The Yunling Jade that has been specially smelted in this way is almost as good as some lower-quality fourth-level spiritual objects.

And as far as he knew, the price to be paid to smelt the third-grade high-grade Yunling Jade to the level in front of him was not small!

It is completely conceivable that the spiritual objects that can use such high-quality Yunling Jade as a container are of such high quality and rare existence.

"Fifty-six spirit-containing jade boxes..."

Chu Mu looked at the jade boxes placed on the wooden shelves. An accurate number came to his mind easily.

He raised his hand and wiped it, and the seal on the jade box in his hand was opened. A biting cold air penetrated out of the jade box. In an instant, it spread along the palm of his hand to his arm. Half of his arm was stained with a bit of frost. .

"Icy Soul Cold Sword Grass."

Staring at a thin 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. With just a little recognition, Chu Mu's breathing became a little faster.

Ice Soul Cold Sword Grass grows in extremely cold and dark places, and its growth limit is fifty years.

Every time a calamity is broken, the grass leaves will have a frost pattern. After five hundred years, the leaves will become sword-shaped, with frost-stained edges, just like a sword stained with frost.

After a thousand years, the blades of grass withered, and as an offering, the blades of grass turned into ice crystals. The three-inch sword body was like a sharp sword reaching into the sky, and the frost on the blade turned into cold air surrounding it.

After a thousand years, a hundred years will be regarded as a calamity.

Every time a calamity is broken, the growth limit is crossed, and the sword body will also grow by one inch.

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

That is...it has grown for fifteen hundred years!

Of course, this time is not absolute.

Just like those who are cultivating immortals, the advancement of cultivation will inevitably take a long time or a short time.

It is not impossible for those with extraordinary talents to form elixirs for hundreds of years.

Those with poor qualifications will find it difficult to pass the level of Qi training throughout their lives.

Some people with abundant resources make rapid progress in their practice, while some people with scarce resources struggle to make progress.

Although the existence of spiritual plants is not as difficult to follow as the cultivation of immortals, there are still 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 situation, and there are also various growth conditions that are equally perfect. Help.

In that kind of perfect environment, the growth rate of spiritual plants will naturally be greatly accelerated. The so-called growth period mainly depends on the quality of 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 classification of the levels of spiritual medicine in the world of immortality, within a hundred years, within the limit of thirty years, the upper, middle and lower grades will be divided into the first level; from a hundred to three hundred years, within the limit of one hundred years, they will be divided into the upper, middle and lower grades. For the second level.

From three hundred to nine hundred years, with a limit of two hundred years, they are divided into upper, middle and lower grades, and belong to the third level.

Above nine hundred years, it is the fourth level.

It is limited to three hundred years and 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-level mid-grade elixir. It can even be said to be a fourth-order high-grade elixir.

Chu Mu raised his hand to explore again. He held another spirit-containing jade box in his hand, and the seal was opened. This time, there was a scorching heat that was completely different from the frost.

The heat wave is rolling, scorching red.

A crimson elixir that looked like a tree with tangled roots also appeared.

It is as red as jade, crystal clear, as if it were an elixir carved from a root, and more like it was carved from beautiful red jade.

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

Chu Mu's arms trembled slightly, and the heat in his eyes suddenly became intense, but soon, this heat was forcibly suppressed by him.

Looking at the other jade boxes again, as one jade box after another was opened, Chu Mu counted all the treasures in his family and whispered the names of elixirs one after another.

And then what came into view were the elixirs that were over a thousand years old one after another.

Chu Mu was very careful and meticulous. He carefully identified and observed each elixir. Afterwards, he carefully restored the seal of the Yunling Jade Box to avoid conflicting effects and damaging this treasure. A thousand-year-old elixir.

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

After returning each jade box to the wooden frame and sealing it temporarily, Chu Mu then looked at the wooden boxes stacked in the two corners.

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

The spirit wood is a famous third-level forbidden spirit tree in the world of immortality. The texture of this spirit wood is hard, and its mystery lies in the forbidden spirit wood.

Containers made of this spiritual wood can perfectly block the erosion of external spiritual energy, and can also prevent the items being placed from leaking out and causing damage to the spiritual energy.

At the same time, this spiritual wood also has some natural spatial properties, which can be suitable for the development of storage space. Although it is difficult to be used as the main material of portable storage devices, if it is used as such a fixed storage device, it is undoubtedly a perfect fit.

Of course, this is also one of the uses of this spirit wood. The greatest use of this spirit wood is "building materials".

The effect of the forbidden, whether it is the monk's cave, the building, the construction of the city, or the flying boat...

All of them can be said to be mysteries that must exist.

This is also the fundamental reason why this spiritual tree is so famous in the world of immortality.

However, because the spirit wood is as high as the third level, it is naturally not an ordinary thing to be able to use this spirit wood.

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

At a rough glance, there are hundreds of large and small wooden boxes in this huge cave space.

Each one is also filled with the aura of space, and it is obvious that there is a universe within.

"Han Ming Shui, Nine Refined Black Iron, Red Flame Pattern Dragon Stone..."

Following the perception of his spiritual consciousness, the names of the spiritual beings were incorporated into his perception one after another. Chu Mu stepped forward and reached a wooden box. He raised his hand a little, and the wooden box array dissipated. His spiritual consciousness penetrated into it. Sure enough, there was a universe inside. .

And inside, there is a brilliant aura.

After sensing it, I realized that this gorgeous spiritual light came from the neatly stacked high-grade spiritual stones.

The entire storage space of the wooden box is filled with high-grade water attribute spiritual stones.

Chu Mu looked at the other wooden boxes. The dozens of wooden boxes in this corner were all filled with high-quality spiritual stones of various attributes.

At the top of these dozens of spiritual stone wooden boxes, there is a wooden box about one foot in size.

The wooden box array was dim, but it was not his fault.

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

The wooden box array has obviously been dim for a while, and the inner space of the partition without the array is clearly included in the perception.

Chu Mu was surprised. He brushed his fingertips and opened the wooden box. Inside, it was not a storage space, but just a simple wooden box, and its lingering spatial aura only existed in the surrounding wooden box space. The infestation of breath.

The inside of the wooden box was... empty.

Chu Mu raised his eyebrows and looked up at the top of the cave. He pondered a little. He raised his hand a little, and the void rippled, and the photo screen flickered.

On the screen, the scene of him standing here is displayed in real time.

As his mind moved, the picture was like going back in time and space. In a flash, all the changes that had happened in this treasure house were revealed.

After just a few breaths and a few months of looking back, the scene suddenly freezes.

It is exactly where he is standing right now, that is this wooden box.

This person is clearly the Supreme Nascent Soul who once sat in Yanyun and led Yanyun for eight hundred years.

The master of the Tianfu lineage, a mid-stage Nascent Soul cultivation level, his name is...Hong Yu!

If he remembered correctly, in that secret world, the Heavenly Talisman Vein Master had also turned into a demon.

Moreover, this Heavenly Talisman Vein Master also escaped the pursuit of the Changsheng Sect Master after the world in the secret realm collapsed, and disappeared into the turbulent flow of space.

"Three months ago..."

Looking at this frozen picture, Chu Mu was thoughtful.

According to time calculation, three months ago, that is, the one-year period of the recruitment order was approaching.

As far as he knew, the time when the Tianfu Vein Master arrived at the Changsheng Sect was around this time.

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

On the eve of rushing to the gate of Changsheng Mountain, a demon who had transformed himself and me came to this treasure house and took away the treasure stored in the wooden box...

Chu Mu’s eyes became brighter and brighter!

The inner core of a demon is the demonized demon body derived from the sky, and its practice system must also be based on the demon!

This means that for a demon, immortal treasures should no longer be of much use.

Unless, it is refined with the spirit of the true devil and turned into a monster...

But the problem is that the price to pay for this kind of training must be huge.

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

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

Otherwise, the Heavenly Talisman Vein Master who had turned into a demon would not deliberately take it away before leaving.

Chu Mu raised his head and looked up. As his thoughts moved, the frozen pictures flowed again, looking back at the previous surveillance pictures.

Once again, it has spanned decades.

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

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

Judging from the appearance and face 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 picture flowed, and in just a few days, Hong Yu hurriedly walked into the treasury and appeared in front of the wooden box.

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

...
