Seeing Mu Yan's affirmative words and expression, Lu Xiao opened his mouth and asked Mu Yan: "Mu Yan, how do you know all this? Brother Zhao and I don't seem to know as much as you know about puppets, demon beasts, and secret realms!" Who are you?"

When the little fat man heard Lu Xiao's question, he also looked at Mu Yan quite suspiciously.

In the eyes of the little fat man, as a Bai Xiaosheng, he doesn't know these things, so how did Mu Yan know?

This is exactly what makes the little fat man wonder!

Mu Yan heard Lu Xiao's question, and felt the little fat man's puzzled gaze again, a trace of unnaturalness flashed in his eyes, and then he explained: "This is also what I learned from an ancient book I saw before, and that book recorded many things on the Elemental Continent that we didn't know!"

Lu Xiao kept looking at Mu Yan, and naturally saw the trace of unnaturalness in his eyes!

However, Lu Xiao soon knew that Mu Yan didn't want to mention his identity to the two, so he found out this statement!

And Mu Yan didn't want to say it, naturally she had a reason, although Lu Xiao wanted to know, but Lu Xiao wouldn't force her to say this!

While the three of them were discussing here, suddenly the three of them felt the ground start to shake!

The three of them looked in the direction of the vibration, and found that it was there, and the yellow sand covered the sky, and they couldn't see anything clearly!

The three of them were ready for battle, and quickly moved sideways towards the place where the yellow sand shook the sky

Not long after, a group of demon beasts appeared in the eyes of Lu Xiao and the others!

I saw a group of huge demon beasts shaped like lizards, rushing in the direction of the three of them!

Just behind this group of lizards there was an even larger lizard that seemed to be commanding the other lizards!

Looking at the lizard in the back, the color of the body almost blended with the yellow sand around it, and at this moment, he looked at Lu Xiao and the three of them with excitement, as if he had seen some delicious food!

Lu Xiao and the three of them also looked at the group of lizards vigilantly!

At this time, Mu Yan spoke again: "This is a demon beast earth lizard, and the strength of ordinary earth lizards is equivalent to the human Yuan realm, but their defense is very strong, and ordinary cultivators at the peak of the Yuan realm have no way to take them!"

When the little fat man heard Mu Yan's words, he said, "Their defense is so strong, and there are still so many of them, so won't we be in trouble again!"

Lu Xiao took over and said: "Not necessarily, I think this group of lizards seems to be dominated by the huge earth lizard in the rear, if we solve that earth lizard, our predicament may be solved!"

Mu Yan also said: "Yes, as the saying goes, the thief captures the king first, as long as we get rid of the earth lizard that looks like the leader, we can get rid of these earth lizards!"

"However, the earth lizard at the back can be used as a leader, and its strength is definitely not weak, according to my observation, it should be a demon beast at the peak of the first order, and it seems that it is not easy for us to come to the leader of the earth lizard through so many earth lizards!" the little fat man said worriedly.

Lu Xiao heard the little fat man's worry, and immediately said: "That's it, my speed should be faster, you two help me cover up, and I will rush to the lizard leader as fast as possible and solve it." The highest realm of these remaining earth lizards is only the demon beasts of the late first order, but most of them are demon beasts in the middle and early stages of the first order, although the number is more than those fire snakes just now, but the overall strength is still not as good as those fire snakes, so the two of you should be able to resist for a while. I'll take out that lizard leader as quickly as I can!"

Mu Yan and the little fat man heard that Lu Xiao volunteered to fight the leader by himself, Mu Yan opened his mouth and said, "Well, this is fine, but you have to be careful, the two of us will try our best to buy time for you!"

The little fat man also nodded to Lu Xiao, and cast a look that made Lu Xiao careful!

Just as the three of them were discussing, the group of earth lizards was already approaching Lu Xiao and the others!

I only heard the leader of the earth lizard screaming at a group of earth lizards running in front, and the group of earth lizards that had just come to Lu Xiao and the three of them instantly dispersed, surrounding Lu Xiao and the three of them in the middle!

Then I heard a long howl from the leader of the earth lizard!

When the group of earth lizards heard this long howl, they all began to move quickly towards the three of them!

Seeing this scene, Lu Xiao cast a reassuring look at Mu Yan and the little fat man, and rushed towards the encirclement formed by this group of earth lizards!

Mu Yan and the little fat man saw that Lu Xiao moved, and they quickly followed!

Lu Xiao came to the group of earth lizards surrounding the three of them, and swung his sword to slash at the several earth lizards in front of him, wanting to open a gap from here!

But before Lu Xiao's sword fell on those earth lizards, he suddenly felt that his movements were sluggish, and his sword-wielding hand stopped moving!

Lu Xiao looked in front of him, only to see that the lower part of the hilt of the long sword in his hand was entangled by the bright red tongues of those earth lizards, no matter how much he pulled the long sword, he couldn't pull the long sword out!

Those earth lizards not far away around saw this scene and rushed towards Lu Xiao!

But at this moment, a golden light flashed, "poof, poof, poof" several times, and Lu Xiao felt that his hand could move again!

After drawing back the long sword, Lu Xiao threw a grateful look at the little fat man!

It turned out that just after Lu Xiao was entangled in the hilt of the sword just now, the little fat man just arrived!

Seeing this scene, the little fat man immediately waved the golden woodcutter in his hand and slashed at the tongues of the earth lizards, and the knife flashed, which also solved Lu Xiao's current predicament!

After Lu Xiao withdrew his long sword, he didn't stop, and swung his long sword towards the earth lizard!

Because of the arrival of Mu Yan and the little fat man, Lu Xiao quickly opened a gap in the encirclement in this direction!

Lu Xiao saw this opportunity, and with his fastest speed, he rushed out of the encirclement and moved sideways towards the earth lizard leader!

As for Mu Yan and the little fat man, they also broke out of the encirclement and helped Lu Xiao behind Lu Xiao to block the pursuit of those other earth lizards!

Lu Xiao rushed to the leader of the earth lizard as fast as he could, and without any extra nonsense, he swung his sword and slashed towards the leader of the earth lizard!

The leader of the earth lizard was also not afraid of Lu Xiao, and stretched out his long tongue to wrap around Lu Xiao's body!

Because Lu Xiao had eaten the loss of these soil lizard tongues just now, when he saw the earth lizard leader stretching out his tongue and attacking him, he immediately flashed to the side, just avoiding the tongue of the earth lizard leader!

Just after Lu Xiao dodged the blow of the earth lizard leader, the long sword he waved in his hand also came to the top of the earth lizard leader's body!

"Poof", a sound of the body being cut reached Lu Xiao's ears!

Immediately after, I heard the leader of the earth lizard hiss, as if he felt a lot of pain!

Lu Xiao's long sword slashed right on the back of the lizard leader, leaving a wound on its body!

It was because of this wound that the leader of the earth lizard felt pain!

Lu Xiao saw that he had only left a wound on the body of this earth lizard leader, and thought of the situation when he had slashed those fire snakes with one sword and one sword before, and he couldn't help but sigh at the strength of this earth lizard's defense!

The leader of the earth lizard felt great pain, and he also entered a violent state in an instant!

Lu Xiao only saw the huge body of the earth lizard leader turn suddenly, and its huge tail swept towards Lu Xiao!

When Lu Xiao saw this scene, he couldn't help but be shocked, instantly changed his body, and flashed to the side again!

But at the same time that Lu Xiao dodged away, the movements in his hands did not stop!

Lu Xiao held the long sword in his hand and sprinted forward violently, "poof", and the long sword stabbed into the head of the earth lizard leader from the jaw!

The leader of the lizard hissed again, and then there was no sound!

Then, with a "bang", the lizard leader was lifeless!

Just after the leader of the lizard was killed by Lu Xiao, the remaining earth lizards who had no wisdom saw that their leader was dead, and immediately stopped caring about the attacks of the little fat man and Mu Yan, and ran away again!

Leave only the yellow sand in the sky!

After dealing with these earth lizards, Lu Xiao wanted to tell Mu Yan and the little fat man to leave.

But before Lu Xiao could call the two of them, Mu Yan walked straight to the huge corpse of the lizard leader, and quickly slashed the head of the lizard leader with the turquoise long sword!

Then, with a long sword, he took out an irregular transparent crystal from his head!

When Lu Xiao saw this crystal block, he couldn't help but be a little puzzled, so he asked, "Mu Yan, what is this, how can it be in that earth lizard's head?"

The little fat man was also quite puzzled when he saw this crystal, although he was Bai Xiaosheng, but after all, he was a low-level cultivator, so there were still many things on the continent that he couldn't touch!

Mu Yan saw the expressions of Lu Xiao and the little fat man, and said, "This is the Yuan Core!"

Lu Xiao and the little fat man looked confused again!

Mu Yan saw the expressions of the two, and couldn't help but feel helpless again!

For these two rookies in the cultivation world, Mu Yan began to feel a little headache!

However, Mu Yan still explained to the two: "The yuan core is a crystal formed by the convergence of its own energy when the demon beast reaches a certain realm, and this crystal contains almost all the energy of a demon beast, which is the root of a demon beast!"

After hearing this, Lu Xiao asked, "Then when the demon beast reaches what realm will the Yuan Core be formed?"

After hearing this, Mu Yan replied: "When ordinary demon beasts reach the peak realm of first-order demon beasts, they are about to be able to absorb the power of heaven and earth elements just like human cultivators, and at that time, they themselves begin to rely on their own power of sensing the elements of heaven and earth to form a yuan core, and when they enter the second-order demon beasts, they will rely on the yuan core to contain the power of heaven and earth elements!"

After Lu Xiao and the little fat man heard this, they didn't feel like rookies at all and nodded!

Seeing this scene, Mu Yan shook her head helplessly.

Next, Mu Yan said: "Therefore, a demon beast that can generally have a meta core means that it is about to enter the realm of a second-order demon beast!"

After hearing this, Lu Xiao couldn't help but say in surprise: "Then we still killed a demon beast that is about to enter the second order this time, this is really good!"

When Mu Yan heard this, she also nodded with a smile!

At this time, the little fat man suddenly said: "We have been in this secret realm for some time, how long are we going to stay here!"

Lu Xiao said: "I don't know, but I don't think I should stay here forever, since this secret realm is called a place of trial, then if you want to go out, you may need some conditions!"

The little fat man said again: "But what conditions do you need?"

Mu Yan then took over and said, "Maybe we need to find something, so as to open some kind of prohibition and teleport us out!"

As soon as she said this, a wry smile suddenly appeared in Mu Yan's eyes, and she seemed to have mentioned something new!

Sure enough, Lu Xiao and Little Fat Man, two rookies in the cultivation world, looked at Mu Yan with a puzzled expression.

Immediately after, Lu Xiao opened his mouth and asked, "What is a prohibition?"

Mu Yan heard Lu Xiao's question, and said, "You two really know too little about the cultivation world, it seems that you two really have time to make up for it!"

When Lu Xiao and the others heard Mu Yan's words, they couldn't help but feel a little ashamed, they both smiled "hehe" and stopped talking!

Seeing the demeanor of the two, Mu Yan didn't say anything, but opened her mouth and said to the two: "The so-called prohibition is something similar to a formation, but the power is not as strong as the formation. Therefore, prohibitions are often used as defense or teleportation, and are generally not used for attacks. You get the idea. ”

When Lu Xiao and the little fat man heard Mu Yan say that the ban was something similar to a formation, they already understood what the prohibition was, so they both nodded and said, "Well, I understand!"

Mu Yan heard that the two understood, so she nodded and smiled.

Then Mu Yan spoke again: "Now that we all understand, then we should leave here now, otherwise we don't know what danger we will encounter again!"

After hearing this, Lu Xiao and the little fat man also said, "Well, let's go." ”

Immediately afterward, the three of them didn't say anything more and quickly left the place

The three of them walked in this desert for a long time, and the yellow sand in the sky kept blowing on the faces and bodies of Lu Xiao and the three of them, but the three of them had no time to take care of it.

Along the way, Lu Xiao and the three of them encountered several waves of demon beast attacks, including groups of demon beasts, as well as individual demon beasts, among which there were even several first-order peak realm demon beasts, but in the end, they were all solved by Lu Xiao and the three of them!

Lu Xiao and the three of them walked in the desert like this, and suddenly a castle made of yellow sand appeared in the eyes of Lu Xiao and the three of them!

I saw that although this castle is completely composed of yellow sand, it does not lose its glorious atmosphere at all, and even these yellow sand can increase the momentum of the castle!

Lu Xiao and the three of them looked at this castle, and they all had a doubt in their hearts!

In the midst of this vast desert, there is such a splendid castle!

Lu Xiao walked towards the castle first.

Before the three of them walked to the gate of this castle, Lu Xiao stretched out his hand and slowly pushed open the gate of this castle!

Pushing open the door, the three of them looked inside, and the hall made of yellow sand came into the eyes of the three of them!

In the center of this hall, there is a throne made of yellow sand, and on the handrail of this throne, there is a dragon-shaped sand sculpture on one side, which is quite atmospheric!

On either side of this throne stood two rows of samurai in armor and armed with broad sand swords!

These samurai are standing there calmly at the moment!

But just as Lu Xiao raised his foot and stepped into the main hall, and as soon as his foot hit the ground, those warriors' eyes widened suddenly, and they began to slowly turn their bodies formed by yellow sand!

When Lu Xiao and the others saw this scene, they couldn't help but be vigilant!

Next, those warriors raised their wide giant swords in their hands!

Seeing this scene, Lu Xiao said to Mu Yan and the little fat man, "Let's attack first, up!"

After saying that, he took the lead and attacked those samurai!

With a "bang", Lu Xiao's fiery red long sword collided with a samurai's wide giant sword made of yellow sand!

However, to Lu Xiao's surprise, after the fiery red long sword collided with the wide giant sword, the wide giant sword made of yellow sand was not damaged in the slightest!

Immediately followed by several "bang, bang, bang", Lu Xiao had a lot of moves with the warrior at this moment!

Then Lu Xiao waved his sword again, blocked the attack of the warrior in front of him, and then retreated to the back!

Stabilizing his figure, Lu Xiao looked at Mu Yan and the little fat man.

I saw that the little fat man was still armed with the golden woodcutter, fighting fiercely with those warriors, although it was a little difficult, but after all, there was no danger to life!

Looking at Mu Yan again, her body is graceful and light, and she seems to be able to deal with those warriors with ease!

But at this moment, behind Mu Yan, a samurai swung that wide giant sword and slashed towards Mu Yan!

And Mu Yan didn't seem to notice!

When Lu Xiao saw this scene, he was immediately shocked, and with a long sword in his hand, he rushed towards the samurai who attacked Mu Yan!

There was another "bang", and Lu Xiao happened to block the warrior's wide giant sword!

Mu Yan felt the abnormality behind her, and couldn't help but look behind her!

Then Mu Yan saw Lu Xiao who was fighting with the earthy yellow samurai!

Soon, Mu Yan understood that it was Lu Xiao who saved herself!

So, Mu Yan threw a grateful look at Lu Xiao!

However, Mu Yan didn't say much, and soon entered the battle group again!
