After searching around, although Chu Mu didn't dare to go too deep, there were still more than ten jade boxes in front of him that were banned by the array forbidden inscriptions.

He carefully confirmed that the jade box was well sealed, and then carefully placed the dozen or so jade boxes in front of him into a storage talisman that had just been opened.

After confirming that it was correct, he looked at the narrow space crack in front of him again, and after a moment of silence, he slowly raised his hand, and in the storage talisman, the broken bamboo dragonfly also appeared in the palm of his hand at this moment.

Looking at the bamboo dragonfly for a moment, he did not linger any longer, and resolutely turned back, and it was not long before he reappeared in the cave.

Chu Mu casually took out a storage talisman, and between the slight movements of his divine sense, several spiritual materials appeared in front of him.

He looked at the broken bamboo dragonfly, and after a little thought, the black mist energy like a tide in the crack in the space, the domineering erosion effect, also appeared in his mind.

The first effect, that is...... Prevent erosion!

"The body size can be a little larger, and the positive and negative five elements array ...... inscribed"

After thinking for a moment, he put away the broken bamboo dragonfly with his backhand, and with a wave of his sleeves, there was a pile of spiritual charcoal in front of him.

Under the flash of fire, the blazing spiritual fire was also presented in front of him.

The goal is clear.

It has the ability to detect and record flights, can sail long distances, and has the ability to conceal, and can resist the erosion of black fog energy.

Under several major conditions, Chu Mu did not dwell too much on the rest of the details, and a general idea was quickly formed in his heart.

Under the scorching of the spiritual fire, pieces of spiritual materials were burned and melted, and under the manipulation of Chu Mu, the fused spiritual materials gradually stretched and evolved, and finally turned into a nearly one-meter-long ...... Dragonfly.

Chu Mu didn't think too much, and basically magnified the design of the bamboo dragonfly before by more than ten times.

In other words, it is a force to ten meetings.

The size of the body has become larger, which means that the spiritual energy that can be accommodated can be increased a lot, and the more spiritual energy can be held, which means that the defensive formation can be supported for a longer time, and it also means that there can be a larger place to inscribe the artifact pattern array forbidden ......

Obviously, the most important ......... has been lost Concealment.

However, being in this secret realm, there is not much time for Chu Mu to think about the design carefully, and if it can be used, it is almost enough.

It took a few hours for the two giant dragonfly reconnaissance magic weapons to be refined, Chu Mu breathed for a while, grabbed the two magic weapons, and jumped into the magma lake again.

"The five lower spirits act as an energy supply, so they should be able to resist it......"

Chu Mu muttered to himself, but he was also a little apprehensive in his heart.

He stuffed five lower-grade spirit stones into the belly of the dragonfly magic weapon, and manipulated the dragonfly magic weapon to fly out of the sea of fire, and finally submerged into the black mist that was like a river.

"I can hold on!"

Feeling the magic weapon defense under the erosion of the black mist, Chu Mu was also relieved.

Five lower spirits, with such consumption, should be able to last for about a quarter of an hour.

In terms of speed, this time is enough to support this giant dragonfly magic weapon, go to the opposite side of the spatial rift, and then return home.

After about half an hour, it was not until the perception of the giant dragonfly that flew out suddenly disappeared that Chu Mu raised his hand and waved, and the other giant dragonfly magic weapon also broke away from the sea of fire and disappeared into the billowing black mist.

Then there was a little nervous waiting.

Perception has disappeared, which means that the giant dragonfly magic weapon has entered another world and has been isolated from perception.

Next, we have to look at this spatial rift, if this spatial rift, in the opposite world, it is also fixed in a certain place.

According to the simple logic of the giant dragonfly, if you go back the way you came, you should be able to return to his hands.

If the spatial rift is only fixed in one direction, then ...... These two giant dragonflies are probably gone forever.

Moreover, with the evil chaos of the black fog energy, if there are creatures in the other world who are attracted to giant dragonflies......

Chu Mu was very vigilant, several magic weapons had been taken out, and even the talisman treasure was already held in the palm of his hand.

If something is wrong, it is a thunderous offensive smash.

Time passed little by little, obviously it was only a moment, but at this time today, for Chu Mu, it was incomparably long.

In front of him, black flames and black fog are intertwined, seemingly endless, and also like unchanged for ten thousand years.

In the middle of it, it seems that you can't feel the passage of time at all.

If it weren't for the occasional flickering of fiery red, it would be endless black!

"It's coming!"

Until the disappeared perception reappeared, Chu Mu was suddenly shocked, staring at the surging black mist.

In a moment, the giant dragonfly magic weapon staggered into his field of vision.

The shoddy stuff didn't seem to have completely withstood the erosion of the black mist's energy.

Chu Mu didn't care too much, and after confirming that the shadow stone hidden in the dragonfly's abdomen was not damaged, he casually threw the broken dragonfly magic weapon into the billowing black mist.

In the shadow stone, the images slowly emerged in his divine consciousness.

In the picture, after the dragonfly magic weapon passes through the spatial crack, it is ...... Endless desolation, dead silence!

The ground is dead and silent, not a single inch of grass grows, and the rocks on the ground are all almost demonic black.

The sky was dim, and it was a black mist visible to the naked eye.

Looking down from the sky, there is no life at all as far as the picture can reach.

Dead silence, dead silence, dead silence!

It's all dead silence!

It's as if the whole world is dead.

When another dragonfly returned, it was the same tattered and in the shadow stone, there was also a dead silence. The picture is not the slightest abnormal.

The two shadow stones were put down, Chu Mu stared at the spatial crack in front of him, pondered for a moment, and finally suppressed the impulse in his heart.

For example, now, even if he can get rid of the black fog energy, if he is really in it all the time, then he will be affected by the erosion of this black fog energy all the time.

It's better not to be bored.

He took a deep look at the spatial crack in front of him, did not hesitate any longer, turned around decisively, and between the surging mana, it was also farther and farther away from the spatial crack where the black mist was surging, and it was also visible to the naked eye.

When he returned to the cave, Chu Mu stood beside the magma lake, muttering for a while, and the Ming Hong knife appeared in front of him, and between the slight movements of his divine consciousness, the knife light appeared.

And with the flickering of the sword light, the originally majestic cave also collapsed visibly with the naked eye.

Huge rocks fell, and in just a few dozen breaths, this magma lake was buried under the collapsed peak.

Under the obstruction of the rocks and soil, with the cultivation of the Qi Realm, unless the collapsed rocks and mud are specifically broken, it is impossible to detect the existence of the magma lake at all.

Immediately, Chu Mu threw down a few more punches, creating the illusion that the vicinity was affected by the big war, and at this time, he led Wangcai to leave quickly.

In the next few days, Chu Mu was still shuttling around the secret realm, avoiding conflicts with other immortal cultivators in the secret realm, while looking for the existence of wolf demon beasts, preparing for the transformation of the bloodline of Wangcai.

As for that spatial rift, Chu Mu had already left it behind, involving a world, whether it was a small world like the secret realm or a vast world like the immortal cultivation realm, it was obviously not something that he could hope for in a small Qi cultivation realm.

Not to mention, there is also that terrifying and evil black mist energy.

Hidden deep in the heart, as if it never happened.

Until the thirtieth day of this secret realm.

On this day, Chu Mu did not hunt the demon beast anymore, but came to the outside of the valley where he had descended when he first came to the secret realm.

After observing it, when the existence of the double-headed giant snake was confirmed, the careful thoughts in Chu Mu's heart immediately dissipated without a trace.

"That's it."

Chu Mu glanced up at the heavenly dome, and he didn't bother to dwell on it, leading Wangcai, just near this valley, he found a hidden place to sit down, waiting for the thirty-day limit to come.

Thirty days, most of the time, are spent in the land of inheritance, the spirit is tense, it is difficult to have leisure, and the rest of the time is either to fight with immortal cultivators, or, to hunt demon beasts.

Rao is his double cultivation of the Dharma body, his physical functions are strong, and he has not slept for thirty days, and he is inevitably a little tired at this time.

"Come, Wangcai, come here!"

He beckoned to Wangcai, and the swarthy and shiny dog cub immediately rushed over and lay beside Chu Oh obediently.

Chu Mu leaned on Wangcai's body, and after sleeping for a while, he raised his hand and wiped it, and a stack of storage charms appeared in his hand.

The secret realm has gained a lot of money.

But he really didn't have time to take a closer look.

The most precious thing is the two inheritances in his sea of knowledge.

There is a volume of the Great Sun Sutra, and there is also a volume of the first part of the General Outline of the Immortal Dao Sect's refining instruments, covering the refining inheritance from the first order to the third order.

Then there were the two bottles of Zhongshi Spirit Milk, which were known as the Refining Elixirs, and the pile of eroded spatial attribute spirit materials that he had obtained at the spatial crack a few days ago.

There are also second-order high-grade red flame iron obtained from Chang Hong'er, second-order low-grade stalactites obtained from the lair of the two-headed giant snake, and half of the head of the two-headed giant snake, all of which are extremely rare spiritual materials.

In the ancient battlefield at the bottom of the lake, a lot of rags were dug up, and together with the loot captured, a total of more than 20 soul stones were accumulated.

The rest are some of the demon beast spirit materials he killed, as well as some elixir spirit materials and spirit stones seized from the loot, as well as some jade books.

Of course, those twenty days of crazy refining weapons are undoubtedly a rare harvest, the unlimited supply of various spiritual materials, the accumulated experience, in this reality, is not ordinarily difficult!

After taking an inventory, Chu Mu put all kinds of elixirs and spiritual materials into storage talismans, and in the end, all that was left was a bunch of jade books.

It's all loot, and he really can't remember exactly which unlucky guy it came from.

He picked up a jade slip casually, probed into his divine sense, and flipped through it quite leisurely.

In fact, since his cultivation became successful, a considerable part of his knowledge of this immortal cultivation realm came from such seizures.

The belongings of immortal cultivators are basically carried with them, and if they kill one person, as long as they do not destroy the storage talisman, they will basically have all their belongings in their pockets.

They are all Qi Realm cultivators, and it is basically impossible for them to have any rare treasures, but this kind of book jade slip will occasionally give him some surprises......
