The direction in which the spiritual veins and yin veins stretch is the deepest part of the valley.

After a few miles, the air began to fill with a thick netherworld yin qi.

Compared to the yin qi that appears in the outside world and the yin veins, it is more rich and cold.

"This place is a good place to cultivate the Hundred Spirits and Spirit Slaves......

Just feeling the rich yin qi in the air around him, Zhang Yan couldn't help but exclaim.

However, what attracted him was not the rich yin qi here, but the abnormality of the ghost spirit bead.

When he entered this valley, Zhang Yan had already sensed the tremor of the spirit bead.

It wasn't until he stood on the spiritual vein that he was sure that the spirit bead was moving differently, and it was at the end of this valley.

At the end of the place, there is this place where the yin aura is strong.

The black fog rolling in layers was even stronger than the hole outside.

Beyond the black fog, you can see a black mountain.

A strong ghostly aura lingered from behind the mountains in front of him.

It's just that on this side of the mountain, there are gusts of wind howling, and sand and gravel sweep from time to time.

"Wind Sand Leaf!"

A few small black trees on the top of the mountain, as well as the leaves on them that also looked like stones and not stones, attracted Zhang Yan's attention.

The leaves on it were exactly the same as the wind sand leaves that Sand Demon Heaven had taken out at the underground auction.

What a strange terrain!

It seems that only such a place where spiritual veins and yin veins coexist will form such an environment!

This wind and sand leaves, thinking about the growth environment is also extremely harsh.

Such a precious and rare elixir, Zhang Yan naturally would not let it go.

After probing the surroundings and finding no other abnormalities, he collected the wind and sand leaves on the mountain ridge one by one.

And when they arrived at the mountain range here, the two spiritual veins had directly sunk into the deeper underground.

Around this spiritual vein, there were also scattered fragmented spirit stones.

Zhang Yan was not in a hurry to collect the yin veins and spiritual veins, but walked towards the top of the mountain range.

The other side of the mountain.

It's a different story.

One step forward is a bottomless abyss.

Dark clouds rose beneath the abyss.

More than ten zhang away, there is nothing in the eyes.

A cold, black wind howled on the edge of the cliff.

What surprised Zhang Yan was the layers of dazzling bright red things condensed from the bottom of the cliff, like blood.

From the blood red, there was a hint of fragrant fragrance and cold breath.

Listen to the Blood!

Zhang Yan couldn't help but be overjoyed, he recognized this thing at once.

In him, there is already a piece of Listening Blood.

That's from the Sand Demon Heaven.

I can't imagine that the Wind Sand Leaf and the Listening Bloodstream both grow in such a place at the same time.

This elixir that contains the extreme yin qi of heaven and earth is hard to find!

Although he didn't know the grade, Zhang Yan knew that the preciousness of this kind of elixir was definitely no less than that of the heaven-level elixir.

On the cliffs, there are scattered more than a dozen pieces of blood.

Further down, you can faintly see more Listening to the Blood.

However, after Zhang Yan collected the above, he did not take any chances.

His gaze fell farther into the abyss.

Zhang Yan frowned, flipped his hand and took out the ghost spirit bead.

Airplanes!

As soon as the ghost spirit bead appeared, it seemed to be pulled by something, and suddenly emitted a brilliant black spiritual light.

And at the moment when Zhang Yan didn't react, he swept down on his own, as fast as lightning.

Seeing this, Zhang Yan couldn't help but be stunned, and then his face changed greatly.

Although the Nether Spirit Bead was still connected to his mind, it seemed to be out of his control at this time.

"Is there something down there?"

Zhang Yan looked at the direction of the ghost spirit bead in a hurry, and his heart was in a hurry, and his divine sense spread away, but he couldn't find the bottom.

Gritting his teeth, the black wings behind him stabbed out, and his whole person was already like a big peng with wings spread, lightning broke through the air, and burst away in the direction of the ghost spirit bead.

Layers of cold and ghostly aura swept all over the body, making Zhang Yan feel cold.

And what made Zhang Yan feel a little bad was that he flew thousands of miles away.

Finally.

Half an hour later.

In a valley full of black sand and barren mountains, it turned and fell.

And what made Zhang Yan gasp was that in the deepest part of this valley, a huge black whirlpool with a total capacity of dozens of zhang kept whistling.

Above it, a black tornado vortex also formed.

The vast Netherworld Yin Qi erupted from the center of the vortex towards the void.

And the yin qi around below is surging towards the whirlpool.

It's just that at this moment, the ghost spirit bead is suspended on the edge of the huge whirlpool.

Airplanes!

As soon as Zhang Yan's gaze fell, the spiritual light of the spirit bead was violent, and with a trembling sound, the countless yin qi in the whirlpool actually began to pour towards the spirit bead on its own.

"This vortex should be one of the entrances to the Netherlands! it seems that the Netherworld Spirit Orb must have a great connection with the Netherlands......"

Seeing this scene, Zhang Yan was shocked for a long time, and then he breathed a sigh of relief, at least now there are no other abnormalities, absorbing these netherworld yin qi, the spirit bead can at least be further improved, and the spirit slave inside, the cultivation will also be further accelerated.

Seeing that there was no danger around him, and there was an empty space, Zhang Yan simply sat down not far from the valley, and also entered the cultivation.

He sat for a day.

When he sensed that the aura around him was thinning, Zhang Yan finally opened his eyes.

At this time, the ghost spirit bead had already swept back to his side.

The cold aura and black aura on it were much stronger than before.

The whirlpool below the valley has become only two zhang in size, and it has become more than ten times smaller.

"Netherlands!"

Looking at the entrance of the whirlpool for a long time, Zhang Yan, who really wanted to really set foot in it, finally shook his head and gave up.

When Donggong Ming handed over this ghost spirit bead to him, he mentioned that this spirit bead was obtained from the netherworld under the ancient tower.

It's just that now, Zhang Yan doesn't want to take this risk now, and there are more important things to do before that.

"Let's wait until we return to the Thousand Spirits Sect and go down from the desolate ancient tower to explore......"

Looking at the surroundings that looked even more desolate due to the thinning of his breath, Zhang Yan sighed, and no longer lingered, his wings fluttered behind his back, and he swept back towards the way he came.

"Senior brother, where have you been, I thought you were eaten by demon beasts, I've been waiting for you for a day!"

Seeing Zhang Yan emerge from the depths of the valley, Ba Huo hurriedly ran over and shouted urgently: "Quick, senior brother, quickly get this yin vein out......

At this time, in the valley, there are still Ding Mojing and Ding Lianxi who have not left.

Ding Mojing's cultivation was sealed, and his body was weak, standing tremblingly and being supported by Ding Lianxi, but he was no different from an ordinary old man.

"The seal in your body, Zhang will help you unlock it first. ”

Seeing that Ding Mojing was here, it was not easy for Zhang Yan to get out of the spiritual vein, otherwise it would spread, and the old man would not be able to stand it, so he turned around and said.

"The old man was offended a lot before, and I hope that Daoyou is not strange! Daoyou not only saved my granddaughter this time, but also did not hesitate to save the old man, Ding has nothing to repay, if you have any requirements in the future, just mention it!"

Ding Mojing could afford to take it and put it down, and bowed to Zhang Yan with shame on his face and said.

Hearing this, Zhang Yan ignored it, and his hand was already probed, grabbing the other party's wrist.

The seal in Ding Mojing's body is quite peculiar, even if the Avatar Monk makes a move, he may not be able to break it.

It is no wonder that Ding Mojing's cultivation in the later period of the Yuan Dynasty was helpless.

It's just that this seal met Zhang Yan.

The Qi of the Void Yuan swam around in the other party's body, and with a few crisp clicks, the sealed cultivation in Ding Mojing's body spread out again.

"The methods of Taoist friends are really shocking!"

Feeling that the seal in his body was gone, Ding Mojing's face was overjoyed, and he bowed again.

At this time, Ding Mojing once again knew the strength of the young man in front of him.

Since the other party can come here, it means that the sand and the hundred flowers outside Mai Qing have not been able to stop each other.

And to be able to crack this Hundred Flowers Heavenly Inscription so lightly, only a Divine Transformation Monk can do it.

Avatar monks?

Such a thought flashed in his mind, and after glancing at the young man, Ding Mojing secretly denied it.

"You go out and wait for Zhang, and then I'll talk about it after I take these two spiritual veins!"

Zhang Yan said, already walking towards the Yin Vein.

See here.

Ding Mojing was also simply, took Ding Lianxi, and swept towards the upper exit, but disappeared in a blink of an eye.
