Longevity starts with learning

After searching around, Chu Mu did not dare to go too deep, but there were still more than ten jade boxes sealed by the array inscriptions in front of him.

He carefully confirmed that the jade boxes were sealed intact, and then carefully placed the ten jade boxes in front of him into a newly opened storage talisman.

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

After staring at the bamboo dragonfly for a moment, he did not stop, and decisively turned back. Not long after, he reappeared in the cave.

Chu Mu casually took out a storage talisman, and when his consciousness moved slightly, several kinds of spiritual materials appeared in front of him.

He looked at the broken bamboo dragonfly, and while thinking a little, the black fog energy in the space crack, like a tide, and the overbearing erosion effect, also appeared in his mind.

The primary function is... to prevent erosion!

"It can be bigger, and the positive and negative five elements array can be engraved..."

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

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

The goal is very clear.

It has the ability to fly reconnaissance and record, can sail over long distances, and has the ability to hide, and can resist the erosion of black fog energy.

Under several major conditions, Chu Mu did not worry too much about the other details, and a rough idea quickly took shape in his mind.

Under the burning of the spiritual fire, pieces of spiritual materials were burned and melted. Under Chu Mu's control, the fused spiritual materials gradually stretched and evolved, and finally turned into a nearly one-meter-long... dragonfly.

Chu Mu did not have too many ideas, basically just magnified the design of the previous bamboo dragonfly by more than ten times.

In other words, one force defeats ten skills.

The larger size means that the spiritual energy that can be accommodated can be increased a lot. More spiritual energy means that the defense formation can last longer, and it also means that there is a larger place to engrave the weapon pattern formation prohibition...

Obviously, the most important... concealment is lost.

However, being in this secret realm, Chu Mu does not have much time to carefully design and make do with it. It is enough to make it work.

It took several hours to refine the two giant dragonfly reconnaissance instruments. Chu Mu took a breath for a while, grabbed the two instruments, and jumped into the magma lake again.

"Five lower spirits serve as energy supply, it should be able to withstand it..."

Chu Mu muttered to himself, but he was a little uneasy.

He stuffed five lower-grade spirit stones into the belly of the dragonfly instrument, manipulated the dragonfly instrument to fly out of the sea of ​​fire, and finally sank into the black fog that was rushing like a river.

"It can hold up!"

Feeling the instrument defense under the erosion of the black fog, Chu Mu was also relieved.

Five lower spirits, at this consumption, should be able to last about a quarter of an hour.

Judging from the speed, this time is enough to support this giant dragonfly magic weapon to go to the other side of the space crack and then return.

About half a quarter of an hour, until the perception of the giant dragonfly that flew out suddenly disappeared, Chu Mu raised his hand and waved, and the other giant dragonfly magic weapon also left the sea of ​​fire and sank into the rolling black fog.

Next, it was a bit of a nervous wait.

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

Next, it depends on this space crack. If this space crack is also fixed in a certain place in the opposite world.

Then according to the simple logical program of the giant dragonfly, it should be able to return to his hands by returning along the original route.

If the space crack 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 opposite world attracted by the giant dragonfly...

Chu Mu was very alert. He had taken out several magic tools, and even the talisman was already in his palm.

If there was anything wrong, it would be a thunderous attack.

Time passed bit by bit. It was only a moment, but at this moment today, it was extremely long for Chu Mu.

In front of him, black flames and black fog intertwined, seemingly endless and unchanged for thousands of years.

Being in it, it seemed that he could not feel the passage of time at all.

If it were not for the occasional flashes of red fire, in front of him, it would be endless black!

"Here it comes!"

Until the disappeared perception reappeared, Chu Mu was suddenly shocked and stared at the surging black fog.

After a while, the giant dragonfly magic tool swayed and emerged in his field of vision.

The crudely made thing did not seem to be able to completely withstand the erosion of the black fog energy.

Chu Mu didn't care too much. After confirming that the image stone hidden in the dragonfly's abdomen was not damaged, he casually threw the broken dragonfly magic weapon into the rolling black fog.

In the image stone, the scenes slowly emerged in his spiritual perception.

In the picture, after the dragonfly magic weapon passed through the space crack, it was... endless desolation and dead silence!

The ground was dead silent, no grass grew, and the land and stones were all black and almost evil.

The sky was dark, and there was a black fog visible to the naked eye.

Looking down from the sky, there was no sign of life anywhere in the picture.

Dead silence, dead silence, dead silence!

All dead silence!

It was as if the whole world was dead.

When the other dragonfly returned, it was also in tatters, and the image stone was also dead silent. There was nothing unusual in the picture.

Putting down the two image stones, Chu Mu stared at the space crack in front of him, pondered for a moment, and finally suppressed the impulse in his heart.

As for him now, even if he could get rid of the black fog energy, if he was really in it all the time, he would be eroded and affected by the black fog energy all the time.

It's better not to make yourself bored.

He took a deep look at the space crack in front of him, and without hesitation, he turned around decisively. As the mana surged, the distance from the space crack where the black fog surged was also visible to the naked eye.

When he returned to the cave again, Chu Mu stood beside the magma lake, pondered for a moment, and the Minghong knife appeared in front of him. As his consciousness moved slightly, the knife light appeared.

And with the flash of the knife light, the cave that was originally towering collapsed visibly to the naked eye.

One after another, huge rocks collapsed, and within just a few dozen breaths, this magma lake was buried under the collapsed mountain.

Under the obstruction of rocks and soil, with the cultivation of Qi training, unless you specifically break through the collapsed rocks and soil, it is impossible to detect the existence of the magma lake.

Then, Chu Mu punched down a few more times, creating the illusion that the area was affected by the war. At this time, he led Wangcai away quickly.

In the next few days, Chu Mu still shuttled around the secret realm, avoiding conflicts with other cultivators in the secret realm, while looking for the existence of wolf monsters, preparing for Wangcai's bloodline transformation.

As for the space crack, Chu Mu had already forgotten it. It involved a world, whether it was a small world like the secret realm or a vast world like the cultivation world, it was obviously not something that he, a small Qi training realm, could touch.

Not to mention, there was also the terrifying and evil black fog energy.

Hidden deep in my heart, as if it had never happened.

It was the 30th day since he came to this secret realm.

On this day, Chu Mu did not hunt monsters again, but came to the valley where he landed when he first came to the secret realm.

After observing for a while, when he confirmed the existence of the two-headed giant snake, Chu Mu's little thoughts disappeared without a trace.

"Forget it."

Chu Mu looked up at the sky, too lazy to bother, and led Wangcai to find a hidden place near this valley to sit down, waiting for the arrival of the 30-day limit.

Most of the 30 days were spent in the inheritance land, and the spirit was tense and there was no leisure. The rest of the time was either fighting with cultivators or hunting monsters.

Even though he practiced both magic and body, his body function was strong, and he was a little tired after 30 days of sleepless nights.

"Come, Wangcai, come here!"

He waved to Wangcai, and the shiny black puppy immediately rushed over and lay down beside Chu Oh obediently.

Chu Mu leaned on Wangcai, and after a short nap, he raised his hand and wiped it, and a stack of storage talismans appeared in his hand.

The trip to the secret realm was very rewarding.

But he really didn't have time to count them carefully.

The most precious thing was the two inheritances in his sea of ​​consciousness.

A volume of the Great Sun Sutra, and the first part of the Xiandao Sect's Refining General Principles, covering the first to third level of refining inheritance.

Then there were two bottles of stalactite spirit milk, which was known as the holy medicine for body refining, and a pile of corroded space attribute spiritual materials he got from the space crack a few days ago.

There was also the second-level upper-grade red flame iron obtained from Chang Honger, the second-level lower-grade stalactite obtained from the two-headed giant snake's nest, and half of the head of the two-headed giant snake, which were also extremely rare spiritual materials.

In the ancient battlefield at the bottom of the lake, a lot of rubbish was dug up, and with the spoils of war, a total of more than 20 soul-condensing stones were accumulated.

The rest were some of the monsters and spiritual materials he had killed, as well as some spiritual medicines and spiritual materials, spiritual stones, and some jade slips and books seized as spoils of war.

Of course, the crazy refining of the equipment for those twenty days was undoubtedly a rare harvest. The unlimited supply of various spiritual materials and the accumulated experience were not ordinary difficult in this reality!

After counting, Chu Mu placed all kinds of spiritual medicines and spiritual materials in the storage talisman in different categories. In the end, all that was left was a pile of jade slips and books.

They were all spoils of war, and he couldn't remember which unlucky guy they came from.

He picked up a jade slip at random, probed into it with his spiritual sense, and flipped through it leisurely.

In fact, since he had achieved success in cultivation, a considerable part of his knowledge of the world of cultivation came from such seizures.

The belongings of the cultivators were basically carried with them. If they killed one person, as long as the storage talisman was not destroyed, basically all the belongings were in their pockets.

They are all cultivators in the Qi training realm, and it is basically impossible for them to have any rare treasures in their homes, but these books and jade slips can occasionally give him some surprises...
