This Demon Yuan Pass has been in Beihe's hands for many years, and he only knows that this thing has one on Zhang Jiuniang in the Yudan period, but he never knows what this thing is.

And since this thing can make the monks of the Yudan period pay great attention to it, and even provoked the two monks of the Yudan-stage to hunt down and kill Zhang Jiuniang, he naturally did not dare to blatantly ask someone to inquire about the origin of this thing. Over the years, he had privately inquired about the Demon Yuan Pass, but perhaps because of his low strength and too few channels to obtain information, he found nothing.

In the end, Beihe put this item in a storage bag, which was sealed by him.

I didn't expect that this Demon Yuan Pass would suddenly undergo such a change.

Beihe looked up at the bottomless passage above his head, swallowed his saliva, and stood in place for a while.

The Demon Abyss Pass seemed to be a key, and now it automatically opened a passage. If Beihe expected it to be good, this passage should lead to the "Demon Abyss", but I don't know what kind of place this Demon Abyss is.

Zhang Jiuniang had a Demon Yuan Pass on his body, and he also had one in his hand, which made Bei He speculate that there might be a lot of this thing.

Now that the Demon Yuan Pass in his hand has been opened, it is very likely that the Demon Yuan Pass in the hands of Zhang Jiuniang and others has also been opened.

If it is true that after the opening of this Demon Abyss Pass, it leads to the Demon Abyss, then all those who have this thing will go to the same place.

This thing made the monks of the Dan Stage fight for it, and he was a low-level monk who had cultivated in the Qi Condensation Stage Fourfold, if he stepped into the passage and was in the same place as those old monsters of the Dan Period, I am afraid that he would not know how he died.

But now that the Demon Abyss Pass is opened, maybe it will be an opportunity for him, which makes Beihe's heart hot again.

Reason told him that for the time being, it was better for him not to try to step into this passage that led to no other place, and that he did not know what was dangerous.

But when he thought that the Black Shadow Lotus would bloom in fifty years, and it would be difficult for him to break through to the Transformation Stage in his life, he gritted his teeth and his eyes fell on that passage.

While it may be dangerous to step into, it can also be a transformation.

Beihe was a decisive person and made a decision immediately in his heart.

At this time, he took out a set of black robes from the storage bag, replacing the gray robes of Injustice Mountain. Then he took out the mask and put it on his face.

Beihe floated up after casting the Sky Command, and stood in front of the dark passageway.

If you step into this passage and encounter any irresistible existence or danger, you should immediately return the way you came.

Then he looked into the passage, and saw that the passage was so deep that he did not know where the end was.

Beihe's body moved, and he sank into the passage.

The moment he stepped into the passage, his heart tensed, and the mana in his body was even more agitated.

To his relief, nothing unusual had happened. Taking a deep breath, he swept deeper into the passage.

Immediately, Beihe discovered that he was in the passage, and after performing the Sky Command, his speed seemed to be dozens or hundreds of times faster than usual.

At this time, he looked back and couldn't help but be startled, just a few breaths, and the black behind him had also become black, where could he see the entrance to the passage.

Beihe's figure suddenly stopped, sweeping in the direction he came.

In a moment, he heard a "hula", and his figure swept out of the passage again, appearing in the stone room where the Black Shadow Lotus was before.

"Whew!"

Beihe let out a long sigh of relief, and then he turned again and stepped into the passage, this time sweeping towards the deepest part without hesitation.

The passage was longer than he had imagined, and it took him half an hour before he saw a small white light appear in front of him. Now he was speeding towards the white light.

"Huh!"

It didn't take long for Beihe to feel that his body was light, and he had already swept out of the passage.

The mana in Beihe's body agitated, and his eyes scanned the surroundings fiercely.

At this time, he found that the place where he was was a stone house, the stone house was gray and white, only two zhang long and wide, and showed a boxy shape.

On one of the walls of the stone house, there is a closed stone door.

Beihe subconsciously glanced back, and then found that the passage behind him was still there.

So he looked at the stone door in front of him, and walked forward, stretching out his hand to push at the stone door.

The stone door was so heavy that it was indifferent when pushed. So Beihe increased his strength, and in the rumbling sound, the stone gate finally opened slowly.

Beyond the stone gate, there was a desert, and the desert was filled with a kind of smoke, which made the whole desert look extremely dark, like a world without the sun.

Not only that, the dim world outside, without any sound, was eerily quiet.

Beihe stood in front of the stone gate, looking at the unknown world under him.

After a little silence, he turned his hand and took out the coffin, and then sacrificed it.

After the volume of the corpse coffin increased significantly, Mo Du swept out of it.

Then Beihe put away the coffin, and as his mind moved, Mo Du walked forward and stepped into the dim desert.

And the moment Modu stepped into the desert, he saw his footsteps suddenly sink. Although he was still moving forward, his pace was slow and heavy.

Bei He frowned under the mask, and after finding that there was no danger, he also stepped out.

And the moment he stepped out of the stone house, his face couldn't help but change slightly, he finally knew why Mo Du's steps were heavy, because stepping in the desert, it seemed that there was a gravity that restrained his body.

What surprised Bei He even more was that as he used the mana in his body, the gravity became more and more obvious.

When the mana in his body worked without reservation, his body trembled wildly and became difficult.

Eventually, Beihe calmed down the mana in his body, and then he felt the gravity suddenly weaken.

The strange situation at the moment made him a little stunned, the secret path could not be caused by some kind of formation that could suppress the mana in the monk's body.

But what is in Modu's body is not mana, but the power of yin and evil, and it will actually be suppressed.

At this time, Mo Du stood three steps in front of Beihe, but his body began to tremble wildly, and it was difficult to take a step forward.

Because Mo Du felt that gravity, he unreservedly activated the yin power in his body, and the result was the same backfire as Beihe just now, the more he used it, the more he was suppressed.

And Mo Du is just a rudimentary-level iron-armored refining corpse, with almost no spiritual wisdom to speak of.

Beihe's heart moved, allowing Mo Du to calm down the yin power in his body, and then saw Mo Du's trembling body gradually calm down.

At this time, he stepped out of the stone house of the North River, swept his eyes left and right, and then breathed a sigh. I saw that on the left and right sides of him, there were many stone houses that were exactly the same as those behind him.

There are two on his left and six on his right, and together with the stone house behind him, there are a total of nine stone houses lined up.

It seems that there are nine Devil's Abyss Passes in total.

Just when Bei He was guessing in his heart what kind of place this dim desert was right now, suddenly the stone house adjacent to him on his right side, in the sound of friction, the heavy stone door slowly opened.

For just a moment, Beihe's heart couldn't help but tense.

Under his gaze, a figure stepped out of the stone house.

I saw that this was an old man dressed in a white robe with white hair and hair. It's just that this person is just like him, with a mask on his face, which makes it impossible to see the true face.

At the moment of stepping out of the stone house, the old man looked at the dim desert world under him, and his eyes showed obvious ecstasy.

Immediately, like Beihe, his eyes subconsciously swept left and right.

"Huh?"

And when he saw Beihe on his side, and Modu in front of Beihe, the old man's eyes suddenly showed a strange look.

For this person's gaze, Beihe's face was gloomy, but he was covered by a mask, and the old man obviously didn't notice it.

The true qi in his body stirred and poured into the mask on his face, and then his spiritual senses suddenly became sharp.

"Shhh

And when he looked at the old man beside him again, he suddenly took a breath of cold air. He had already judged by the aura that shrouded this old man that the person on his side was a monk of the Yudan stage.

Just when Bei He's heart was startled, another rumbling sound came from his left.

I saw that the stone house on the far left was also opened, and another figure walked out of the stone door.

It was a woman in a long white dress, who was delicate in shape, but with a cloak on her head, and it was impossible to see her true face.

And after seeing this woman, Beihe's face changed again.

By enveloping this woman's aura, he judged that this was also a monk in the Yudan period.

When this woman appeared, she was as ecstatic as the white-haired old man when she saw the desert world in front of her.

When she looked to the right and saw Beihe and the white-haired old man, she looked stunned, but soon came back to her senses and looked into the depths of the desert.

At this time, Beihe's heartbeat accelerated uncontrollably, and there were already two monks in the Yudan period, and it seemed that the next people who appeared here were probably all old monsters with terrifying strength, and his cultivation would be eaten without saying that there were not even bones left.

With this in mind, he cautiously stepped back. At the same time, his mind moved, and Mo Du also followed him back.

After a short time, the two returned to the stone house together.

At this time, Beihe's heart was pounding, and then he didn't hesitate to close the stone door, turn around and step into the passage behind him.

But at this moment, he found that the woman in the white dress on the left and right and the white-haired old man were actually walking in the desert at this moment, walking towards the depths of the desert, and the two of them turned a blind eye to him.

Surprised, Beihe's movements stopped and did not move for the time being. It seems that in the depths of this desert, there should be some other mystery that attracts these monks of the Yudan period.

"Rumble ......"

When Beihe thought so, he heard the sound of the stone door opening again.

He didn't see it, but he could tell it was coming from his right.

In just a moment, he saw a figure, following the woman and the old man, also walking into the depths of the desert.

It was a man in armor with a helmet on his head that showed only a pair of eyes. It seems that none of the people who appear here want others to see their true faces.

"Huh!"

After seeing this person, Bei He sighed lightly in his heart, because he judged from the aura that enveloped this person that this was actually a cultivator of the Transformation Yuan Stage, not the Yudan Stage.
