The Dark Lord was extremely fast, and it didn't take him a few minutes to rush to the bottom of that cliff.

Lu You and his party followed quickly, and when they arrived, they found that this cliff was more and more high, and the vines were overgrown, especially the bottom was covered by dense vines.

This is simply a Jedi, there is no passage to speak of, just when everyone was puzzled, the Dark Demon King directly reached out and tore off a large vine at the root of the cliff, and then Lu You and the five people were surprised to find that at the bottom of the cliff, a natural cave appeared.

Everyone's eyes widened again, and the Great Demon King of Darkness smiled confidently and got into it without saying a word.

"Let's go, keep up, I feel the aura inside this cave getting stronger and stronger!"

Lu You opened his mouth, and everyone quickly followed, and the group disappeared into this mysterious canyon.

Along the cave, everyone walked all the way and found that the cave seemed to lead directly to a certain place underground, and all the way down, it was a natural karst cave, and there was a cave in it.

The deeper they walked, the more intense the spiritual power contained in the air became, and not only did everyone not feel depressed chest tightness, but they were refreshed and their whole body was full of true qi.

"What the hell is this place, Lu You! The aura here is already approaching our orchard!"

Qin Yurou couldn't help but speak.

In addition to Li Xiaorou, Long Xue, Bai Jingxuan, and even the Dark Great Demon King who was hurrying forward in front were stunned.

Bai Jingxuan said curiously: "Brother Lu, is there still a spiritual vein in your house?"

Lu You was directly at a loss: "Spirit vein, what spirit vein? I'm just an orchard!"

"Just kidding, what orchard can have such a strong aura, could it be that all the fairy fruits and fairy trees in your orchard?" Bai Jingxuan obviously didn't believe it.

Lu You's head was suddenly full of black lines, and he really wanted to answer in his heart, you did guess right, but when the words came to his mouth, he shook his head and smiled.

"Well, that's right, what kind ......of spiritual veins did you just say?" Lu You's eyes widened.

Li Xiaorou said: "It should be! I have long heard that in the depths of these 100,000 mountains, there is a spiritual vein, which is a national secret land, accounting for nearly one-tenth of the country's spiritual stone vein output, which is extremely huge! I didn't expect it to be here!"

"That base of Qianlong No. 1, I think it is to take care of this precious spiritual vein, if it weren't for this accident, we wouldn't have been able to get close to the belly of this spiritual vein!"

Everyone felt that this speculation was very reliable, and as they spoke, everyone went all the way down the cave, and it is estimated that they all walked twenty or thirty miles.

Suddenly, in front of the cave, a bright light appeared, hazy, and very conspicuous in the dim underground.

Everyone stepped up, and when they stepped into the light, their eyes suddenly lit up, and they saw a spacious passage appear in front of them.

This passage was apparently excavated by a machine, and the traces of artificiality are obvious, and the length, width and height are about three meters each.

"Boom, this king smelled the smell of fresh spirit stones, I really didn't expect that on such a poor and backward planet, there would be such a spirit vein, God help me!"

The Dark Lord sniffed hard, a greedy expression on his face.

Lu You and the others were also full of surprise, since stepping into this passage, the intensity of the aura had simply multiplied exponentially, and everyone felt that the flow of true qi in the whole body had accelerated, and the cells were active, and they couldn't wait to immediately sit cross-legged on the ground and concentrate on cultivating.

Being able to cultivate in such a place will definitely get twice the result with half the effort, and one day is enough to be worth many days outside.

Call!

Suddenly, the figure of the Great Demon King of Darkness turned into a phantom, and began to rush along the entire passage, visible to the naked eye, with the actions of the Great Demon King of Darkness, the overwhelming spiritual power around him frantically converged towards the other party's body, and the situation was as if the Great Demon King of Darkness had incarnated into a terrifying devouring machine, and all the spiritual energy returned to the sea.

The situation was simply terrifying, Lu You and the others behind him were all dumbfounded, this old monster is worthy of being one of the demon kings of the dignified Desolate Demon Realm, where is this absorbing spiritual power, it is simply devouring!

"Oh no, if the strength of the Great Demon King of Darkness increases, then maybe the Hundred Tribulation Karmic Fire and the Hundred Treasure Chest will not be able to contain each other, and it will definitely become a disaster at that time!

A bolt of lightning suddenly flashed through his mind, and Lu You's face immediately changed greatly, but the Dark Great Demon King had already disappeared in front of him, and the distance was too far for the treasure chest to react.

Lu You didn't even have time to say hello to Qin Yurou, Li Xiao and the others, the whole person was really angry under his feet, turned into lightning and quickly chased down, behind him, Qin Yurou, Li Xiaorou, Bai Jingxuan, and Long Xue Although they didn't know what was going on, they still chased after him quickly.

Boom!

For a while, the arrogant laughter of the Great Demon King of Darkness was heard from time to time in the entire underground passage, and countless heaven and earth spiritual qi frantically converged towards each other, forming a terrifying spiritual power storm.

Lu You gritted his teeth and launched a rapid chase, but the speed of the Dark Great Demon King was too fast, and it was obviously impossible to catch up in a short period of time.

Lu You tried to regain the feeling of stepping on the tip of the wind before, but the strange thing was that that wonderful state did not appear again.

"It turns out that the magical state of running wantonly and stepping on the tip of the wind still needs the wind as a medium, otherwise with my current ability, it is not enough to perform!"

Lu You quickly realized his state, but in this underground passage, where would the wind appear, there was no choice but to grit his teeth and continue to chase.

Lu You's only hope now is that the Dark Great Demon King doesn't know that he is going to accept the other party, so when he gets to a certain place, he will take the initiative to stop.

In this way, the Dark Great Demon King was in front, Lu You was behind, and then Qin Yurou, Li Xiaorou, Long Xue, and Bai Jingxuan were the four of them, and the whole team showed a strange posture, rushing along the underground passage.

The Great Demon King of Darkness seems to have a purpose, the intricate underground passages are like nothing, and after a while, the place where they are is is becoming more and more remote, but the spiritual energy in the passage is about to condense into spiritual rain, and it is gray.

The aura of heaven and earth here has reached a very terrifying level, and the mouth and nose are full of rich heaven and earth spiritual power between running, even if they are running rapidly, the five of Lu You can feel that the true qi in their bodies is constantly growing.

They are all like this, not to mention the Dark Great Demon King himself, from the beginning to now, almost more than an hour has passed, and with the terrifying devouring method of the other party, it is simply a huge amount of absorption.

Fortunately, along the way, Lu You did not lose it, and firmly hung the other party's tail.

Suddenly, at this moment, the Dark Great Demon King, who had been running in front of him, suddenly stopped his pace, and Lu You was overjoyed when he saw this, and he accelerated his pace again to catch up.

At the moment of contact, Lu You was just about to use his mind to put the Great Demon King of Darkness into the treasure chest, but suddenly, his eyes froze, and his thoughts stopped abruptly, staring straight ahead.

He followed the Dark Demon King for some time, and he came to a spiritual vein that was being excavated, and the road ahead was blocked.

But this is not the most important thing, what caught Lu You's attention was that at the end of this spiritual vein, two huge beasts as huge as a hill appeared at this moment!

At this moment, the two fierce beasts were passively alarmed, turned around, and Lu You clearly saw that the two fierce beasts had a bull head and a horse body, two wings on their backs, and two eyes were golden, while the other looked like a crocodile spirit, covered with shining scales, but it had three short legs as thick as a bucket, and also had a pair of golden eyes.

At this moment, these two mountain-like fierce beasts were holding a crystal with a glowing body with their claws, with dense tooth marks on it, and the fierce beast was constantly chewing on crystal fragments in its mouth.

"That's ...... Spirit Stones!"

The moment he saw the crystal, Lu You's eyes suddenly shrank, and his heart beat violently, he had seen spirit stones, and at this moment, there were still five hundred low-grade spirit stones rewarded by the academy in the treasure chest!

It's just that what surprised Lu You was that the spirit stones on the claws of the two fierce beasts at this moment, whether in terms of color or purity, were much better than the spirit stones in his treasure chest, could it be ......

An unbelievable thought rose from Lu You's heart, and then the blood flow in his body accelerated!

In today's cultivation world, there are four kinds of spirit stones, namely low-grade spirit stones, middle-grade spirit stones, high-grade spirit stones, and the legendary top-grade spirit stones.

Lower-grade spirit stones are already an important resource for cultivation pursued by all cultivators in the cultivation world today, and a lower-grade spirit stone has been fried to 100,000 pieces on the black market, which is also a priceless situation, let alone other higher-level spirit stones.

In today's Great Xia Kingdom's cultivation world, the country has a very strict control over the rare resource of spirit stones, and Lu You has never seen a higher-level spirit stone so far, but this does not prevent him from judging the approximate grade of the spirit stone by its color and purity.

With just one glance, Lu You judged that the spirit stones in the claws of the two fierce beasts were at least two levels higher than the lower grade spirit stones!

Thinking that the high-grade spirit stone, which was regarded as a holy object by cultivators, was actually so spoiled by two savage beasts, Lu You's fist couldn't help but clench it.

But what shocked him was far more than that, at this moment, he could only hear the sneer of the Dark Great Demon King slowly sounding: "What level of big coffee did this king think, it turned out that it was just two beast king-level demons stealing food here!"

What the?!

When the Dark Great Demon King's calm words fell, Lu You was immediately startled, and even Qin Yurou, Li Xiaorou, Bai Jingxuan, and Long Xue, who came from behind out of breath, instantly stopped their steps, looking stunned as if they had been struck by lightning.

What did they just hear?!

Beastmaster!

And it's two!

The beast king who was looking for it outside turned the sky turned over turned over and hid here, gnawing on the precious high-grade spirit stones, looking at ease.

They're not dreaming, are they?

Qin Yurou and the others were dumbfounded, at this time, the two fierce beasts in front of them stuffed the high-grade spirit stones in their claws into their fanged mouths, and their bites clicked, as if they were eating snacks, but those golden eyes exuded an infinite ferocious aura, staring condescendingly at the Great Demon King of Darkness!

As for the five Lu You, they were directly ignored by them!

"You're not human!"

Suddenly, the beastmaster with the head of a bull and a horse spoke.
