When the two of them swam away, Bian Wolf's eyes rolled, and he was thinking about whether to catch up and kill their kung fu, when suddenly there was a large sound of breaking the air above.

Bian Wolf was startled, and hurriedly slid the pool water to chase in the direction where Xiao Liu and Miao Lanlan left, and then the sound of "Puff Pass!" sounded one after another, and Bian Wolf looked back and saw that these huge noises were made by the fall of those demon beasts that were chasing them before!

It seems that these guys have not escaped the fate of being swallowed up by the swamp, and many of them have fallen into it.

There was a lot of movement here, so Xiao Liu and Miao Lanlan also found out, but after they just glanced at it, they sped up their speed and rushed forward without looking back.

About a quarter of an hour later, the pool began to narrow, and the mountain walls on both sides squeezed the pool to the middle, forming a jump of river water seven or eight feet wide, Xiao Liu would dive down from time to time to investigate the situation under his feet, not that he was worried about a sneak attack by demon beasts, but he wanted to see where the bones of those demon beasts continued.

Since they fell, the countless skeletons of demon beasts and people under their feet have made Xiao Liu feel that this place is not good, and even now, there are still many bones at the bottom of the river below them.

"How did these monsters die? With such a huge number, it will definitely not be as simple as falling into a swamp and dying. ”

With this question, Xiao Liu pulled Miao Lanlan all the way upstream, and the wolf didn't know what the idea was, but he didn't catch up this time, but just hung far behind them and followed all the way.

For this damn guy, Xiao Liu doesn't have time to deal with it for the time being, if he really doesn't open his eyes and wants to come over and do it, then Xiao Liu will let him know that there are some people he can't afford to provoke!

The three of them, divided into two groups, swam silently along the underground river.

Miao Lanlan's physical exertion was too large, and Xiao Liu could only pull her to swim together, but fortunately, the consumption in the water was relatively small, so Xiao Liu was not too strenuous .

But that continued until a day later, when things changed.

Before they knew it, the underground river began to become very turbulent, and the resistance of the water increased, which caused them to need to spend more physical strength and vitality every time they advanced.

Because Xiaoliu has one person, the consumption is naturally greater.

At the same time, he found that the skeletons of the demon beasts at the bottom of the river had become fewer, and only some small corpses sank inside

"These demon beasts have all reached the strength of the Earth Immortal Realm, and the reason why they are not big should be the ability to control their appearance. This is the sign of the Ground Rank Demon Beast. ”

"It's all the corpses of earth-level demon beasts?How could such a powerful existence die in a big chunk?What is there in front of this?!"

Xiao Liu's question Mo Wu couldn't answer, so he could only say

"I don't know exactly what's ahead of me, but it's certainly not going to be easy. You have to be more careful, if it doesn't work, use self-hypnosis, then we can fight. ”

Even Mo Wu said so, and the pressure in Xiao Liu's heart can be imagined.

As they got closer and closer to the source of the river, the corpses of the demon beasts under their feet became more powerful, and some of them had even reached the fourth or fifth level or even seven or eight levels!

Although the wolf Bian who was following them was not aware of this, the demon beasts that fell together felt it most obviously, so they wisely chose to retreat.

When Bian Wolf found out, the group of demon beasts had already turned around and turned back, and none of them followed.

"What the hell is going on, how could those deadly monsters just leave?"

Bian Wolf was puzzled, he also saw the corpses of demon beasts under his feet, but he didn't have Mo Wu's guidance, he didn't know that the corpses under their feet now, each of them had the strength to easily crush them before he was alive!

In this way, another day passed, the river became more turbulent, and at the same time, there were fewer and fewer corpses under their feet, but their strength before their death was also rising all the way, and finally, they even reached the terrifying heavenly level!

Regarding this news, Xiao Liu has always been secretly numb in his scalp and did not tell Miao Lanlan.

Because even if he said it, it would not make any difference, and if there was a real danger here, then they must not be able to resist it in the slightest.

In this way, there is no difference between saying it and not saying it, for Miao Lanlan.

"Hmm, there's a big natural hole in front of it!"

With the help of his extraordinary eyesight, Xiao Liu saw the situation ahead clearly, and an empty area appeared in his eyes.

A quarter of an hour later, Xiao Liu took Miao Lanlan to this place, and the surrounding mountain walls spread out to both sides, forming a spacious underground cave, and even forming a waterhole again.

At the edge of the waterhole, there were some rocks that could be footed, and Xiao Liu panted and took Miao Lanlan ashore.

After two consecutive days and two nights of swimming, the originally energetic Xiaoliu was a little unbearable, not to mention Miao Lanlan, who had already consumed a lot.

"Look, boy. ”

Mo Wu suddenly spoke at this time, Xiao Liu looked at the mountain wall behind him according to his prompt, and he found that there was a cave about five zhang high on this mountain wall, and a breath that made him feel his soul tremble emanated from it.

Inside this cave, it seemed that an ancient fierce beast was dormant, but the breath that naturally emanated made Xiao Liu feel unbearable.

He swallowed a mouthful of saliva, not knowing whether he should run away now or go over and check.

"Boy, the stuff in there is dead. You don't have to be afraid. ”

Mo Wu's words made Xiao Liu's pressure suddenly decrease, just now he just looked at the cave, and he felt as if he had come to the feet of a terrifying beast, and he felt like he was about to be crushed to death by the other party at any time.

"Lan, Sister Lan, you take a rest here, and I'll go see what's in the cave. ”

After Xiao Liu's words were finished, he just wanted to get up, but suddenly felt that he was being pulled by, and when he turned around, he saw Miao Lanlan's pale little face

"Brother, you can't go! I feel that there is a super terrifying thing in there, and if you go, you will definitely die! So you must not go, let's get out of here quickly, don't alarm it!"

Miao Lanlan, like Xiao Liu, had an instinctive fear of the cave, and Xiao Liu patted her hand after hearing the words and said

"Sister Lan, that thing is dead, don't worry. Trust me, I'll be back soon. ”

However, Miao Lanlan didn't seem to be at ease at all, she grabbed Xiao Liu to death, and finally struggled to stand up and gritted her silver teeth

"In that case, then I'll go with you!"

Her tone was undoubted, Xiao Liu couldn't resist her, and finally had to nod and agree.

When the two of them set off, Bian Wolf also came here, and after he looked at the target of Xiao Liu and Miao Lanlan's action, that is, the mysterious cave, he immediately felt a pressure from his soul, which made him involuntarily take two steps back.

"These two guys, what did they find? These are all the corpses of demon beasts, could it be caused by something amazing?"

Wolf pondered suspiciously for a moment, then he mustered up his courage and began to move towards the cave.

A moment later, Xiao Liu took Miao Lanlan to the entrance of the cave, compared to just now, the fierce aura generated by the things in the cave was countless times greater, and even made Xiao Liu feel that if he took a step further, he would die immediately and inexplicably.

Miao Lanlan couldn't bear it anymore, she was already too consumed, and her resistance was also a little worse.

"Boy, step in, and when you get in, you don't feel pressure. ”

Mo Wu in his mind spoke at this critical moment.

Xiao Liu has always trusted him, so a ruthlessness flashed in his eyes, and he hugged Miao Lanlan and took the last step with the determination to die.

As soon as his feet stepped on the ground in the cave, his whole body immediately became extremely relaxed, and all the stress and fear disappeared in an instant, as if everything he had just felt was fake.

Miao Lanlan also stood up by herself, looking around suspiciously, in this cave, it was obvious that there were traces of being excavated, but it was very rough.

And the cave is so deep that you can't see anything in it.

Xiao Liu and Miao Lanlan glanced at each other, and then the two of them began to walk inward vigilantly.

Although they were cautious along the way, nothing happened in the end, but the bones in the river outside the cave always reminded them that the existence that lived here was probably the culprit that caused the death of those powerful demon beasts.

Miao Lanlan didn't know that the strength of those dead demon beasts was better, but Xiao Liu knew very well in his heart that among those bones, there were many terrifying guys who were in the Heavenly Immortal Realm before they were alive!

The cave grew wider and wider, and soon the two of them came to the end, a larger stone cave with some rotting grass and trees on the ground, which were piled together to form a large circular nest-like thing.

And in this lair, lying on its stomach is a gray-white skeleton.

"Is this the corpse of that horrible monster?"

Xiao Liu asked silently in his heart.

"That's right, this guy's strength has reached the peak of the Heavenly Rank before his death, and one foot has already entered the realm of immortal beasts. It must have been dead for many years, and I guess the dead air produced by this thing leaked out after its death, causing the group of guys in the river outside to follow the smell of corpses, but they couldn't resist the strong coercion and dead air, and finally died. That's why this mausoleum-like scene was formed. ”

"If I'm guess right, this guy should have suffered something and died when he wanted to break through the realm. Its aura already had a trace of an immortal beast, but it failed in the end. The dead demon beasts outside probably came for its corpse, eating its flesh and blood can greatly increase the speed of the demon beasts outside, but none of them succeeded. ”

Xiao Liu was silent for a moment after hearing this, and then he set his eyes on the corpse of this ancient beast that was once high above, it seemed that its size before its death was not too big, it was only more than three zhang long, with horns on its head, a long tail behind it, and its sharp fangs and claws were still well preserved.

When he looked at the belly of the ancient beast's corpse, Xiao Liu suddenly found that at the position of its belly, there was a dark green bead that was secretly emitting a ghostly light.

Thinking of Mo Wu's words before, Xiao Liu thought to himself

"This guy shouldn't have died because he ate this bead and finally broke through and failed, right?"

With this question in mind, Xiao Liu let go of Miao Lanlan's hand and walked forward alone......
