Xiao Yun's sudden attack immediately caused a commotion in the cave.

The cry of "huh" became more and more poignant.

At this time, Xiao Yun also understood.

The sudden sense of fear that I had just now turned out to be affected by the crying of these ghost-faced bats, and under the fright, I didn't even have the heart to fight back.

Fortunately, the black orb was suddenly activated, injecting a wave of intoxication into the hidden meridians, allowing him to recover his senses, otherwise the consequences would be unpredictable.

However, from this point of view, it seems that this Demon Soul Skill does not only open a hidden meridian in the human body, but more importantly, by injecting drunkenness into this hidden meridian, it can improve people's mental resistance.

Just now he was coldly overshadowed by these ghost-faced bats, and Xiao Yun's face sank like water at this time.

After the drunkenness he spewed out just now and the sword he swept out, Xiao Yun also understood these ghost-faced bats at this time, that is, with a crying sound and that terrifying appearance of a dead ghost, in terms of strength, at most, it was a first-level demon beast, even an ordinary wine-like wine realm, and he could also sweep away these damn ghost-faced bats.

Xiao Yun's heart was full of anger, staring gloomily at the ghost-faced bats with wings around him, slowly raised the Snow Crystal Sword, opened his mouth and squirted a mouthful of rich wine power.

As soon as Jiu Li came into contact with the Snow Crystal Sword, it immediately melted into it as if it had touched a sponge, and quickly spread to the entire body of the Snow Crystal Sword at a speed visible to the naked eye.

Xiao Yun was already ready to go on a killing spree.

At this time, these ghost-faced bats also seemed to be enraged by Xiao Yun's calmness, and after flying around Xiao Yun for a long time, in the midst of a terrible cry, more than a dozen ghost-faced bats pounced on Xiao Yun again.

The white sword light immediately flashed again.

The ghost-faced bats that pounced were all neatly split into two pieces by the Snow Crystal Sword.

"With the help of you, I can practice my blue light sword technique. Xiao Yun said coldly.

After speaking, without waiting for the ghost-faced bat to pounce for the third time, he took the initiative to pounce.

Snow-white sword light immediately raged inside the pitch-black cavern.

For a moment, the ghost in the cave cried wolf.

Where can the ghost-faced bats that attack by interfering with their sanity be able to withstand this kind of frontal kill, just in an instant, more than a hundred ghost-faced bats have been chopped down.

However, I don't know if these ghost-faced bats are fierce by nature, or if they are hungry and ruthless, at this time, they still don't know how to flee for their lives, but they still surround Xiao Yun.

Of course, Xiao Yun was even more unceremonious, chopping melons and vegetables back and forth in the hole.

In a short time, the ground was already covered with the corpses of ghost-faced bats, and blood was everywhere.

Finally, the ghost-faced bats really couldn't hold it anymore, and many ghost-faced bats were already frightened, giving up Xiao Yun, and Pu flapped their wings and flew towards the depths of the cave.

There are fewer and fewer ghost-faced bats left, and the crying is getting weaker and weaker.

However, the ghost-faced bats seemed to be accustomed to the darkness, and none of them flew out of the cave, and all of them fled deeper into the cave.

"Cry to me again!"

Xiao Yun was covered in blood, blocking the ghost-faced bats in front of him who wanted to fly in, and with a flash of sword light, dozens of ghost-faced bats were swept into two.

However, there are still many ghost-faced bats that have taken the opportunity to escape into the depths of the cave.

Soon, around Xiao Yun, there was no more ghost-faced bats, and the sound of crying came from the depths of the cave, and many ghost-faced bats had already fled far away.

"It's not that easy!"

Xiao Yun rose up to kill, holding the snow crystal sword, and chased towards the depths of the cave without reluctance.

He Shangshu once said that Xiao Yun seems to be peaceful, but he is actually vicious in his heart. And this trip to the cave, Xiao Yun was almost killed by the ghost-faced bat's control of his mind just now, where would he give up?!

Looking at Xiao Yun's gloomy expression at this time, if he didn't clean up the ghost-faced bats in this cave, he couldn't get rid of the hatred in his heart.

Perhaps sensing that Xiao Yun continued to chase, the ghost-faced bat's already weakened cry became terrible again.

Listening to the sound, these frightened ghost-faced bats were forced to continue to flee for their lives in the depths like lost dogs.

"I don't believe there is no end to this cave. ”

Xiao Yun held the Night Pearl in his left hand and went deep into the cave unhurriedly.

After half a cup of tea, I only heard the cry of the ghost-faced bat getting closer and closer, and it seemed that there was no escape ahead, and it was already in the deepest part of the cave.

Xiao Yun had a cruel smile on his face, and rushed over with a quickened pace.

In the misty white light of the Night Pearl, he immediately saw the many ghost-faced bats on the top of the cave in front of him, constantly flapping their wings, and desperate.

For a while, the ghost-faced bat fell into the situation of being slaughtered again.

The depths of the cavern were again full of ghosts and wolves.

I don't know how many ghost-faced bats I killed, and finally, after Xiao Yun swept with a sword, he found that there were no more flying ghost-faced bats in front of him.

There is only one left.

The grimace of this ghost-faced bat is particularly terrifying, one grimace is half the size of a normal ghost-faced bat, and the two eyes behind the black hair are shining, which is especially terrifying in the pitch-black cave.

But at this time, the green eyes of this ghost-faced bat were no longer flashing with a strange light, but full of fear.

It flapped its wings slowly, as if signaling something to Xiao Yun.

Xiao Yun took two steps, and at this time he also saw clearly, this was already the end of the cave, and there was a damp earth wall in front of him, and there was no road.

And on the ground next to the ghost-faced bat, which looked like a leader, was a black box.

Xiao Yun looked at the black box, then at the ghost-faced bat, and suddenly asked, "Do you want to exchange this box for your life?"

The ghost-faced bat seemed to understand, and nodded desperately.

This situation seems strange, but when you think about it, it is not strange.

The ghost-faced bat is only a first-level demon beast, and the first-level demon beast does not have divine intelligence at all, but in this netherworld, it seems that everything cannot be measured by the situation in the human world.

Although the strength of this ghost-faced bat is extremely weak, it has the ability to interfere with people's sanity, and most of them are born with an advantage over other demon beasts in terms of sanity.

It may not have understood what Xiao Yun was saying, but it could sense Xiao Yun's mind when he spoke, and thus felt the meaning of Xiao Yun's words.

At this time, the ghost-faced bat flapped its wings more frequently on the black box, as if pleading.

Xiao Yun pondered for a moment, put down the long sword, and walked over.

Next to the skeleton at the entrance of the cave, there were Night Pearls and Qiankun bracelets, but these ghost-faced bats never moved. But they had taken the black box to the deepest part of the cave, could it be that there was something important to them hidden in the black box?

Seeing Xiao Yun coming over, the ghost-faced bat consciously flapped its wings twice and flew aside.

It didn't take the opportunity to fly away, as if it was afraid of angering Xiao Yun.

Xiao Yun bent down and picked up the black box.

I don't know how long this black box has existed, and the lines on it have long been blurred, but if you identify it carefully, it seems to be carved as an insect-like monster.

"Wu Clan?!" Xiao Yungang was shocked as soon as he could barely make out the patterns on it.

He had seen the corpse of the Wu clan in the secret passage of Junzhu Mountain, and he immediately recognized it.

"This box was left by the Wu Clan?" Xiao Yun thought in surprise.

At that moment, Xiao Yun gently opened the black box.

Looking inside, Xiao Yun was stunned.

I saw three things in turn inside the box, a bamboo slip with small black characters written on it, a black bracelet, and a key with a strange shape.

Xiao Yun took out the bamboo slip first.

Unexpectedly, as soon as I came into contact with the bamboo slips, with a little force, the piece under the bamboo slips immediately turned into powder.

Obviously, this bamboo slip is too old, it has become completely brittle, and it will be completely destroyed at the slightest touch.

After thinking about it, Xiao Yun gently spewed out a sip of fan-shaped wine, lifted the bamboo slip, slowly rose up, and then stood upright in the air.

Xiao Yun knew that his sip of wine would not last long, so he hurriedly leaned on the night pearl and quickly read the words on the bamboo slip.

There is not much content on the bamboo slip, and after a while, Xiao Yun read all the words, although the lower right corner of the bamboo slip was accidentally touched into powder by Xiao Yun just now, destroying a few words, but it does not affect the understanding of the whole text.

And after Xiao Yun just finished reading, the wine power that held the bamboo slips dissipated.

The bamboo slips immediately turned into countless powders and fell with a splash.

Xiao Yun looked at the slowly falling bamboo slip powder and was silent.

There is not much content in the bamboo slips, but almost all of them are things that Xiao Yun has never heard of.

It turned out that the black box was left by a grave keeper.

This person wrote in the bamboo slip that his people have lived in the underworld since ancient times, guarding an underground cemetery called the "Dark Tomb", and in his generation, I don't know how many years have passed.

But one day, suddenly a human race came to the underworld from some channel, and found the dark tomb, and wanted to break in, so his people began to fight with this human race, but they didn't expect that although the cultivation of this human race was suppressed, the exercises were extremely powerful, and all the people were killed.

After almost costing the lives of the entire clan, they finally trapped this man in the ancient tomb, in order to prevent anyone from coming to the ancient tomb in the future, his people made a mechanism at the entrance of the ancient tomb, this mechanism requires three corresponding keys to open, and after the construction of this mechanism, the three keys are also in the hands of each of the three elders of the clan.

But after this battle, his people were left with little left, and they no longer had the ability to continue to guard the ancient tomb, so they wanted to leave this place, but on the way, they encountered a group of powerful demon beasts attacking, he tried his best to escape, but the oil had run out, and he fled to this underground cave in a panic.

In addition to these, the bamboo slips also mention ghost-faced bats.

It turned out that the ghost-faced bat was a spirit animal raised by this person, and when he fled, he came to this underground cave with him.

According to the content of the bamboo slips, the ghost-faced bat is born with the ability of consciousness, and when the person's mind is cultivated to a certain level, especially after possessing the soul power, it will be able to communicate with the ghost-faced bat.

And the ghost-faced bat has a special talent, it can sense herbs, demon beasts, and even treasures that are useful to the mind, so that it can bring great benefits to its owner in the cultivation of soul power, but the ghost-faced bat also has a natural weakness, that is, it can't see the sun, and can only move in the dark, otherwise it will immediately rot and die.

At the same time, this person instructed in the bamboo slip that if later people see the content of the bamboo slip, please be kind to the ghost-faced bat, the black bracelet in the box, called the "spirit animal ring", can put the ghost-faced bat into it and carry it with you.

That's all there is to the bamboo slips.

After reading it, Xiao Yun understood some of the doubts just now.

No wonder the ghost-faced bats only flee to the depths of the cave but do not fly out of the cave, it seems that the ghost-faced bats are not only afraid of sunlight, but also afraid of the light in the sky.

However, the ghost-faced bat was not unfamiliar with the white light of the Night Pearl, and was obviously not afraid of the light emitted by this treasure.

The black box was placed in the deepest part of the cave, obviously left by the writer of the bamboo slips, and the reason why I didn't see this person's body was because it was too old, and his body had long since turned to ashes. At the same time, the ghost-faced bats in this cave are definitely not the spirit beasts raised by this person, but the descendants of his spirit beast bats.

As a result, the ghost-faced bat's talent for sanity is appalling.

There can only be one explanation for the fact that after the death of the original ghost-faced bat, its descendants are still guarding the black box in the cave, and the original ghost-faced bats passed on this task to their own descendants, and it has been passed down from generation to generation until now.

And this kind of communication, for demon beasts, can obviously only be done through mental communication.

From this point of view, the Ghost-faced Bat's mental abilities are unimaginable.

But these doubts that have come to an understanding are far less than Xiao Yun's new incomprehension after seeing the bamboo slips.
