After all, the law of survival is the law of survival, one thing descends to another, and there are creatures that all dinosaurs can't match, so they will naturally retreat.

The plants and reptiles here are more ancient, although there are no trilobites that are beyond the norm, but just by virtue of the simple colors and textures within the eye, as well as the dull deep blue of the sky, all convey a message that this place is not simple.

The three of them only reached the boundary of the seemingly non-existent boundary in the center of the grassland, but they can feel that the air here is even thinner, even if the air was thin thousands of years ago, hundreds of millions of years ago, but the oxygen content here has dropped significantly, and the chest cavity of the three people can also feel an obvious sense of oppression, just like the thinning of the air on the plateau is a truth, everyone's differences will always reflect different, but in the game, it will only increase the consumption of physical strength, and there will be no other feelings.

It's just that the three people who were already physically exhausted were even worse at this time, and as far as the eye could see, not a single player could see it, but the environment here was a little gloomy and terrifying. But a minute passed, the three of them wheezed violently and their undulating chests gradually eased down at this time, and the three of them took out the water in their backpacks almost at the same time and took a sip, at this time, the clear sweet spring was the best comfort for the three of them, and then took out the medicine bottle that quickly recovered their energy and took a sip, at this time the tense body gradually softened, Zhao Xiaoan clenched his fists, and felt that the blood in the tendons and veins slowed down at this time.

The three of them, who had reorganized a little, had recovered most of their strength.

"This place is not simple, be careful..."Zhao Xiaoan reminded at the right time.

Where those ferocious carnivorous dragons dare not enter, what reason do they have not to be careful.

Perhaps it won't be long before they see what's sacred in this mysterious atmosphere.

Although you can detour along the edge, do not touch the mold, but finally have arrived here, do not go in to see is really unwilling, opportunities and dangers coexist, the more dangerous places are accompanied by more opportunities, which is also natural, of course, it is not excluded that there are relics left by the designer in the small cave, that will soar into the sky, carp jumping dragon gate, although there is only one in 100 million possibilities.

Xue Qing exhaled in Zhao Xiao'an's ear at this time, "Xiao'an, you have to protect Meixu." ”

"Hmm." Zhao Xiaoan just replied softly, and didn't have the intention of joking, the verdant ancient tree was too strange.

Zhao Xiaoan looked at the green ancient tree carefully at this time, it was just a glimpse before, and he didn't pay too much attention to those ancient trees, maybe just ordinary ancient trees, but now Zhao Xiaoan won't think so, because only the green ancient trees stand in the clouds within a radius of one mile, and the clouds and mist are just ordinary clouds, light and ethereal clouds, without a substantial shape.

The outermost trees are far taller and more burly than the red pines in the forest. Even from a hundred meters away, a few centimeters of dark brown veins vividly reflected the vitality of the ancient tree and the growth rings, and there were some dead insects on the trunk of the ancient tree, and the dust had already covered them, and then in the white dust, the wings were only skeletons, as if they would be disillusioned in the next moment. In addition to the eye-catching dead insects, the strong and outward-radiating branches made Zhao Xiaoan recall once again the World Tree that stood a few hours ago and didn't know how many years it was, but it was just a small thing, and the leaves that were not lush were still dropping leaves at this time, and the sparse sound was like the leaves falling on the heart, scraping people so much. Looking over the verdant periphery of the ancient trees, the ancient trees in the inner periphery are even more short, not so much dwarf, but rather deformed by the squeezing of the "beast", everything else is not unusual, those deformed ancient trees may not be unusual, perhaps......

At this time, it is naturally good to be able to recover some physical strength as much as possible, taking advantage of the moment when it was not disturbed by the demonic beast, now if you can recover your physical strength a few more points, then the odds of winning are a few points greater, at this time it is just a very slow flight forward, as if you are walking at a general sliding speed, you don't need to consume any physical strength, at this time everything around you needs to be vigilant, after all, the unknown enemy is in the dark, and the three of them are in the light.

The three of them were gliding at the speed of flying like walking, about two hundred meters away from the ancient tree, and at this time, they saw the deep bottomless pit from the gap in the ancient tree, and the three of them cooperated with the recovery effect of the blood bottle, and their physical strength had recovered a seven, seven, eight, eight.

Closer, the details of the ancient tree can be seen clearly, the ancient tree is slightly undulating...

Zhao Xiaoan's heart was almost stagnant at this time, and the two girls also discovered the clue at this time.

No details were noticed at a distance of five hundred meters.

I wiped my eyes again, the fact that the ancient tree was undulating had not changed, and it was going up and down...

But there is no such thing as an earthquake, so why do ancient trees behave like animal bodies? Just as the chest cavity is filled with air and then exhaled slowly, the rise and fall of the chest cavity is breathing, which drives the whole body to do multi-person movements at a uniform speed.

Could it be an ancient tree spirit? And dozens of them?

This also seems to explain why there are dozens of trees in the middle of the steppe...

But it doesn't seem to be that simple, and many doubts are still not clearly explained.

The three of them continued to get closer, but they were also thinking about whether to spare it, after all, there were only dozens of trees, and they couldn't go to the sky, right?

But I still didn't plan to do so....

Now there is no such intention to back down.

It's just that the only thing I haven't figured out is why the pterosaur is afraid, even if the ancient tree will have a living vine, but the pterosaur can rise to a height of 10,000 meters, why should it be afraid of a few vines?

Even if the vines have great ability, they can't touch the air at a height of 10,000 meters, right?

These dozens of ancient trees occupied a radius of dozens of meters, and the fine sand and gravel on the land also began to shake slightly at this time.

At this time, Zhao Xiaoan noticed that the entire central boundary of the grassland began to tremble slightly, although it was not violent, but the air seemed to be shaking because of this, and he could also feel the strange feeling of the air flow on his face, and a long-lasting sharp cry of a pterosaur suddenly came from in the distance.

Zhao Xiaoan took out the spear, vigilant of every move around him, Mei Xu and Xue Qing also held the weapon in their hands at this time, the atmosphere at this time has begun to be wrong, at this time not only the ancient trees are undulating, but the entire space is constantly shaking, but there is no danger in addition.

The three of them stared at the strangeness in the space for about half a minute, and a scene that shocked the three of them happened.

The ancient trees in the mist are being uprooted at this moment! The ancient tree, which was already towering into the sky, was even more upright at this time. A rumbling sound rang out, accompanied by a tearing sound of flesh breaking. The shaking of the ground became more and more intense, and the fine sand continued to beat on the ground. The ancient trees stretched out towards the sky, and the ancient trees at the edge slanted in all directions.

After two or three seconds, the ancient tree stretched upwards faster and faster, and the fog was swept away in an instant, and the darkness in the ancient tree was also illuminated by the sunlight at this time, and the sunlight penetrated through the cracks of the ancient tree, and the dust was spreading in the wisps of colorful light.

After the giant roots of the ancient tree were pulled out of the ground, the thick roots had many small branches, and the tiny roots of the ancient tree were often intertwined with each other, an inseparable appearance.

But the tendrils were not stuck in the dirt at all, but in a black behemoth, and its figure finally came to the surface.

The tremors on the ground became more and more intense, and they could be felt almost for miles.

Half of its body was exposed to the air from the grass beneath the ground, and it knew what kind of behemoth it was, and the sand gradually slipped from a large chunk of its back.

Its back holds up an ancient forest with a radius of one mile!

The pure black back is inlaid with some golden scales, and some of the crystal scales are hidden in the ancient forest, but they still emit some bright light in the sunlight.

A large pit appeared in the ground, and it was the pit that filled the monster, like a cemetery built specifically for the monster.

Its back was perfectly displayed in front of the three of them, and then the rest of the monster's body was revealed, its head peeking out of the dirt, its wings that stretched for a hundred meters, and its tail.

Another ten seconds passed, and its whole body was presented in front of Zhao Xiaoan at a glance.

To put it simply, this is the ultimate enlarged version of the pterosaur, but it is magnified by a thousand times.

But this is not simply the category of pterosaurs.

The ancient trees on the periphery were hanging on the broad back of the pterosaur, and the leaves on it also rubbed against the pterodactyl's skin at this time to make a sound of brushing the ground.

The trunk of the ancient tree in the center glows with a faint cyan glow.

The cyan glow was inconspicuous, but it did flow like a winding stream.

The rest of the place is much the same as that of a pterosaur, and the claws and teeth are no longer as weak as chicken ribs, far sharper than the claws of a carnivorous dragon.

Ordinary pterosaurs are too small to be reflected in the details, but this 100-meter-long pterosaur is even centimeter-long even if the pore hair is centimeter-long, and all of them are presented in the retina.

The hearts of the three of them were almost stagnant at this time, not only in terms of momentum, but also in terms of strength.

This also explains why the heart of this grassland does not have any creatures that dare to offend.

This is not simply the Longtan Tiger's Den, it is almost the end of the world!
