More than 30,000 zhang deep underground, there is a small underground world with its own space.

Here, it is the place where the Tianyuan Pearl of the Fairy Spirit Cave is located - the Mixed Yuan Cave.

The Cave Tianyuan Bead seemed to be the sun of this small world, suspended hundreds of zhang above the ground.

Around the Dongtian Yuan Pearl, there is a misty and chaotic aura, and from a distance, it looks like a brilliant glow, revealing the mystery in the splendor.

The terrifying heavy pressure suction and repulsion force emanated from the Cave Heaven Yuan Bead at the same time, filling the entire Mixed Yuan Cave World. That kind of contradictory existence makes people can't help but feel like they are at a loss to vomit blood.

Directly below the Dongtian Yuan Pearl, there is a liquid lake with a size of more than 100 zhang.

In the lake, there was an incomparably rich breath of source marrow fluid emanating from it, filling the entire Mixed Element Cave.

Even outside the outer wall of the Mixed Yuan Cave, Wu Yan could clearly capture it through the crystal window of the drilling vehicle.

"Shhh

Wu Yan, who had just entered the Mixed Yuan Cave, was suddenly stunned by the source marrow liquid lake he saw in front of him.

Although it was still more than a thousand zhang away from the source marrow liquid lake, Wu Yan could clearly judge from his breath that the source marrow liquid of this lake was much richer than the source marrow liquid he purified from the source lake water!

"Unexpectedly, in the Mixed Yuan Cave of the Immortal Spirit Realm, so many Source Marrow Liquid have been bred!

At this moment, Wu Yan really wanted to rush into the Mixed Yuan Cave, regardless of it, and directly take away the source marrow liquid of this pool!

However, it is clear that this is not an ordinary difficulty for him.

On the outer wall of the Mixed Element Cave, the gravity formed by suction and repulsion is tens of thousands of times higher!

Even if the drilling vehicle had already opened the two-star function, it could only make a small opening in the outer wall, and if it wanted to completely enter the Mixed Yuan Cave, it was still impossible to do so.

This place is already so terrifying, the center of the Mixed Element Cave, where the source marrow liquid lake is located, the gravity is so strong, you can imagine it!

In other words, although the source marrow liquid was good, if you want to take it, I am afraid that there is no other way than to refine the Cave Tianyuan Bead.

And in addition to the pool of source marrow liquid, on the ground of the Mixed Yuan Cave with a radius of thousands of zhang, there were some plants that had grown for an unknown number of years.

Those plants were full of desolate aura, and the aura emanating from them was even stronger than the immortal aura on the source marrow liquid.

Wu Yan felt that any of these plants, any of them, had probably surpassed the cognition of the immortal realm cultivators.

After counting carefully, Wu Yan found that on the ground of the cave, the closer to the source marrow fluid lake, the more lush and numerous the plants grew, and far away from the source marrow solution, there were only a few sparse and sporadic plants.

However, those plants that were far away from the source marrow fluid exuded an even stranger aura, even with Wu Yan's knowledge, he couldn't tell what kind of plant it was.

In the entire cavern, there are about seventy plants growing next to the source marrow liquid lake, and the four sides away from the source marrow solution lake add up to only eight plants.

Aside from the source marrow lakes and plants, there doesn't seem to be anything else worth paying attention to in the entire Hybrid Cavern.

However, Wu Yan would not think that there was only so much simplicity in this Mixed Yuan Cave.

There must be something he didn't know.

"C-Six, do the math and see how the drill truck can get into this cavern. ”

Wu Yan couldn't hold back the burning heat in his heart, and couldn't help but command to the god machine next to him.

The body of this machine qì person is marked with the word Bingliu, and Wu Yan then calls him Bingliu.

Hearing this, Bingliu kept clicking on the light screen on the console and calculating, and the number of items was constantly being calculated.

Soon, Bingliu completed the calculation and reported to Wu Yanyu seriously: "Your Excellency, the gravity here has reached 34,670 times that of ordinary gravity, and the destructive power formed by pressure has reached two stars. The pressure of the world inside the cave must have exceeded that of two stars. With the pressure resistance of the drilling vehicle, I am afraid it will be difficult to resist, and please think twice about the captain. ”

"Don't you see that pool of Source Marrow Fluid inside, if you can remove them all, it should be enough to activate the god-class mothership, right?"

Wu Yan pointed to the source marrow liquid lake in the cave and agitated to Bingliu.

Hearing Wu Yan's words, Bingliu pressed a button on the operation table, and a red light suddenly shot out from the front of the drilling vehicle.

The red light then began to scan the entire cavern.

After a while, the red light that had been scanned was retracted into the drilling vehicle, and Bingliu clicked on the light screen to report to Wu Yan the number of items that had been scanned.

"Your Excellency, this is a core cave that maintains the stability of the space world, and there is a core inside. The liquid beneath the earth's core is more than two stars of energy. On all sides of the energy liquid, there are more than 100,000 cubic meters of energy stones. If all of these can be excavated, it will be enough to maintain the operation of the god-class mothership for thousands of years. ”

What made Wu Yan a little dumbfounded was that the information reported by Bingliu contained so much content.

He really didn't guess wrong, the stones here seemed to be inconspicuous, and they were all top-level immortal source stones!

When he got treasures such as the god-level mothership, the god machine disk, and the god machine beast training park, Wu Yan was still worried, where to get enough energy stones to open these treasures, but he didn't expect that this unexpected teleportation would actually find a cave with such rich energy.

However, it is obviously not an easy task to remove these power stones and energy liquids.

"There are eighty plants with a vitality of more than two stars, and an ancient beast with a vitality of more than two stars. ”

"A beast with a vitality of more than two stars?"

Wu Yan was shocked!

According to the judgment of the Divine Machine Clan's vitality of the creatures of the Hongmeng Three Realms, his current vitality has not yet reached one star, and there is actually an ancient beast with a vitality of more than two stars hidden here!

This means that the strength of this ancient beast is likely to have reached the peak of the Taiyi Realm.

Wu Yan once judged according to the division of the cultivator realm of the Hongmeng Three Realms by the Shenji Clan, the strength of the three realms of the Taiyi Realm is equivalent to between one star and two stars, and the strength of the three realms of the Daluo Realm is equivalent to between two stars and three stars. The three realms of the Great Sage Realm are equivalent to between three and four stars.

Of course, this division is only a rough distinction and is not necessarily entirely accurate.

This ancient fierce beast has a vitality of more than two stars, which means that its longevity and cultivation have reached the peak of Taiyi Xuan Immortal.

When Wu Yan heard Bingliu's report, he immediately had the urge to scold his mother.

His gaze repeatedly scanned the entire Mixed Element Cave, and found that except for the source marrow liquid lake, there might be an ancient fierce beast hidden, and there was no trace of the fierce beast anywhere else.

This is too fucking tricky, isn't it?

If you want to carry the source marrow liquid and dig up the top-level immortal source stone, you will inevitably alarm that ancient fierce beast.

"Bingliu, do you think there is a way for us to enter the cave and remove these things inside?"

Wu Yan asked Bingliu again.

Bingliu first shook his head and said, "With our current drilling vehicle and our despicable ability to resist pressure, there is no possibility of entering this cave. Unless His Excellency the Captain is able to remove the three-star drill vehicle and the three-star god machine from the god-class mothership, there is no possibility of entering the cave and carrying these power stone energy liquids. ”

After saying this, Bingliu's gaze swept over Wu Yan's body again, making Wu Yan feel quite uncomfortable.

"Why do you think so of me?"

"Your Excellency, I beg your pardon to say that with your current vitality, entering this cave will be in danger of your life, and it is best not to risk it. Bingliu said seriously.

"Is there no other way than to start the Samsung drilling vehicle and the Samsung God Machine QÌ people?"

Wu Yan was extremely depressed, scratching his head and thinking hard about countermeasures.

At this moment, a sonorous sound of breaking stones came from above.

Wu Yan was taken aback, and glanced upwards with his Divine Immortal Sense, and found that it was actually Luo Ba Yunkong holding the Demon Suppression Immortal Puppet, appearing less than a hundred zhang away from the Mixed Yuan Cave.

Depending on the situation, he only needed to take one more step down to reach the outer wall of the Mixed Element Cave.

However, this step is obviously not so easy to cross.

The outer wall of the Mixed Yuan Cave already has the power of almost two stars, although the Demon Suppression Immortal Puppet is powerful, but the stone used by Luo Bayun to activate it is only a mid-level Immortal Source Stone after all.

At this time, the power that the Demon Suppression Immortal Puppet can exert is at most equivalent to the realm of Taiyi Heavenly Immortal, and it is impossible to break through the outer wall of the Mixed Yuan Cave.

Sure enough, the Demon Suppression Immortal Puppet couldn't take that step anyway, and was blocked out of the Mixed Yuan Cave.

Luo Bayun, who was hidden inside the Demon Suppression Immortal Puppet, did not rush to replace the Immortal Source Stone of the Demon Suppression Immortal Puppet, but used his immortal sense to probe into the Divine Sea of the Demon Suppression Immortal Puppet, and through the Divine Sea of the Demon Suppression Immortal Puppet, he probed and scanned the Mixed Yuan Cave.

When he saw the incomparably rich source marrow fluid in the Mixed Yuan Cave, as well as the plants around the source marrow liquid lake, he immediately laughed excitedly!

"I can't imagine it, I can't imagine it, there are so many Immortal Source Source Essence in this Mixed Yuan Cave! There are so many Da Luo Immortal Pills! It's gone! It's gone! I'm really developed this time! Hahaha!"

At this moment, the person closest to the Mixed Yuan Cave was still thousands of zhang away, and Luo Bayun was not afraid that his laughter would be heard by others.

Wu Yan, who was only more than 100 zhang away from him, heard Luo Bayun's voice, but came back to his senses in shock.

It was the first time he had heard the name of Da Luo Immortal Medicine. It seems that these treasures that surpass the top-level immortal plants should be the Great Luo Immortal Medicine.

And between the Da Luo Immortal Medicine and the top-level Immortal Plant, I think there should be Taiyi Immortal Medicine.

"It's just that the gravity here is so terrifying. The Demon Suppression Immortal Puppet can now exert the strength of the Taiyi Heavenly Immortal, but it can't even break through the outer wall of the Mixed Yuan Cave, it seems that it must be equipped with the high-level Immortal Source Stone obtained from that secret realm, and let it exert the strength of the Taiyi Xuan Immortal before it can enter the Mixed Yuan Cave!"

Luo Bayun muttered to himself, the Divine Sea of the Demon Immortal Puppet had already glanced at the Cave Heaven Yuan Bead suspended in the center of the cave, and his eyes flashed with excitement and greed.

And just when Luo Bayun was a little carried away with excitement, Wu Yan, who was hiding on the outer wall of the Mixed Yuan Cave, soon discovered that there was another shadow that appeared silently on the outer wall of the Mixed Yuan Cave, and it was only less than a hundred zhang away from him.

"It's him! I'm not mistaken, he's the most terrifying of the six!"

That shadow was none other than the person Wu Yan had noticed earlier who could lock him and the drill vehicle with his immortal sense-17096+d6su9h+10889769->
