The more the two walked inside, the more difficult it was to breathe, and the oxygen content was extremely low, so they had to put on an oxygen mask, but what puzzled the two was that according to common sense, where the vegetation is luxuriant, there should be more and more oxygen, why is it the opposite?

In fact, this situation is very normal, the plants here are different from those plants outside, most of the plants have to photosynthesize, will absorb carbon dioxide and release oxygen, but at night when there is no photosynthesis, it will absorb a certain amount of oxygen, obviously here the plants enjoy the probability of photosynthesis is greatly reduced, so most of the time almost in the absorption of oxygen in the water, resulting in the surrounding oxygen content becomes very low.

Luo Ping turned on the professional flashlight, stood on the periphery and took a closer look, and found that this forest was said to be a forest, but because there was no wind, it didn't look much different from the stone bells outside, and it looked extremely weird.

Long Xin opened a simple windsock with him, and followed Luo Ping to walk inside, because the oxygen was fixed, and there was not much left, so both of them sped up.

This forest is very dense, the two looked at the sides, they have all blocked, they can only pass through the forest, neither of them thought that they had just experienced a deep cave dive, and now they have to walk through this strange forest, looking at each other, they are helpless.

But there is no way, the entrance of the waterfall can't get in, you can only pass through from here, after Fei Lao vigorously peeled off the branches of the trees, Luo Ping saw that Long Xin was just about to step into it, and immediately pulled her up, and then cautiously pulled it in with a wooden stick to try it, and was stunned, there was a swamp several meters deep in it, and when the wooden stick touched the bottom, some would come out, and you didn't need to look at it to know that it was some kind of poisonous gas.

Long Xin was startled, although this equipment can prevent poisoning, but if it really falls in, then this set of equipment will become her life-seeking soul, there have been many diving enthusiasts, because the plants in the water are entangled in the equipment and cause Zuihou to suffocate to death.

After retreating to the open area, Luo Ping looked up at the water and waterfall in the distance, and made a gesture towards the dragon's heart to light a fire, indicating that if it was possible, he could burn all the forests that were in the way.

Long Xin looked around, although there was no end in sight here, and they could hide in the water when it burned, but the forest here didn't know how big it was, and he was afraid that when the time came, it would be really a matter of stealing chickens and rice, but when he thought that the forest was lying in front of him, it was undoubtedly blocking their way to survive, and it was very difficult for a while.

Luo Ping is actually very helpless, once people are trapped in some kind of narrow area or sealed area, they are often psychologically up-to-date and unbearable, which can be seen from many earthquakes, tsunamis and other natural disasters, many people are scared to death, Luo Ping is not a saint, in this case, although he has been able to calm down, but several breakthroughs before and after have hit a wall, or let him start to be a little impatient.

"I really can't, let's see if there is any other way out." As a man, Luo Ping couldn't be crushed by his own heart, and smiled at Long Xin: "We have already come through so many difficulties before, and we will survive this time, besides, in this kind of terrain, although the route is complicated, it also shows that we may find other ways out at any time." ”

Long Xin nodded, so many difficulties have come over before, and now it is like this, it can be said that the dead pig is not afraid of boiling water, nodded, and followed Luo Ping in the opposite direction.

The two walked for about half an hour, and the windsock in Long Xin's hand still didn't move at all, which made the two quite disappointed, seeing that it was still dark in front of them, so they had to find a dry place to sit down and rest first.

"Wait a minute, I'll get some food, you can raise the fire first." Luo Ping peeled off the branches on the dragon's head, and then walked towards a small stream in the distance to see if he could get two small fish.

Feeling Luo Ping's gentle side, Long Xin was in a much better mood and began to look for something to burn around, but there were some slippery moss all around, and it was difficult to find something to burn, so Long Xin had to go further to see if there were any withered branches.

Luo Ping stretched out his hand to interview in the stream, and found that the temperature was really cool and flying, like an ice cellar, you must know that this is the weather in June, and the big city is as hot as a stove, and here, the water has a biting coldness, as if it has been beaten by electricity.

Call!

Luo Ping took a deep breath, then jumped down and quickly dived into the icy water, he only longed for a few small fish now, so that he could recover some strength, nothing else.

The stream water is very clear, most of the river bottom can be seen clearly, according to the principle of fish phototaxis, Luo Ping hit the light above his head on the water surface, and then the whole body squatted quietly in the water, after a while, Luo Ping felt that his whole body was frozen and numb, that layer of protective equipment was to deal with summer diving activities, so the inside was not thick, in this environment, it did not play much role.

But even so, Luo Ping still didn't move, he knew that in the cold water environment, the metabolism of the fish was relatively slow, and the movements were relatively slow, but the keen jǐng tixìng was first-class, if there was any wind and grass, it would be hidden immediately, so he could only wait there bitterly.

Half an hour passed, and just when Luo Ping was about to lose confidence, suddenly there was a slightly shaking shadow under the light in the distance.

"There's a fish coming!" Although Luo Ping wasn't quite sure how big the fish was, or whether there was only one, it was obvious that he knew that a fish was coming, which made Luo Ping a little excited, thinking that it had been nearly an hour, and it was finally not in vain.

The fish first circled around, and then seemed to be very surprised by the sudden extra Luo Ping, and immediately swam back a meter away, and then stared at Luo Ping like this, as if trying to determine what this thing in front of him was.

Originally, as long as the fish swam half a meter further, Luo Ping was sure to catch it, but he ran away at the critical moment, which made Luo Ping have a headache, so he had to hold his breath and continue to wait.

After the fish was stagnant for more than ten minutes, he finally couldn't help but be curious, and slowly swam over, when Luo Ping saw the whole fish, he was stunned to find that the fish was almost transparent, which just verified Darwin's theory of evolution, only species that adapt to a special environment can survive, if the fish in front of him is black sè, it is estimated that Luo Ping would have been barbecued a long time ago.

"Goo-goo...... Goo ......"

Just when the fish surfaced and was about to breathe, Luo Ping stretched out his hand and said that it was too late and that it was fast, and he stretched out his fingers to directly clamp the fish steadily, which was a unique skill he practiced when he was a child.

The transparent fish still wanted to struggle, but unfortunately Luo Ping's two fingers were full of strength, and after struggling for a while, he had no strength, so he could only watch his body get out of the water.

"It's really cāo eggs, in order to catch you, they are almost frozen into disabilities." Luo Ping let out a long breath and climbed ashore to prepare to walk back, at this moment, he suddenly heard a roar, this sound was definitely not the dragon's heart, and suddenly Luo Ping's whole heart was hung in his throat, thinking how could there be a large wild animal here?

At this moment, he couldn't think much about it, and threw the transparent fish into a depression at once, and then ran towards the source of the sound quickly.

On the way to Luo Ping, Long Xin was struggling hard, just now she couldn't find any dry firewood nearby, so she wanted to go farther, but she saw that there was a hole full of moss, and many of them had withered, it was just right to use as fuel, but just when she was about to collect moss, suddenly a huge monster with four wings rushed out of the hole and pounced on it, Long Xin was startled, before she and Luo Ping based on the traces on the ground, almost judged that large animals were unlikely to appear here, So when I suddenly saw such an animal, I was a little dazed.

The giant beast was very brutal, and grabbed the dragon heart directly with one claw, and the dragon heart hurriedly retreated, and glided out more than ten meters directly, but it was still touched by the sharp claws of the giant beast, and the light on its head was directly broken, which suddenly plunged the dragon heart into darkness.

Originally, the strength of the dragon heart would never be afraid of this giant beast, but now that the surroundings are dark, although the dragon heart has good night vision, but it is compared with ordinary people, here, she can't compare with the aborigines like the giant beast, and she will soon fall behind, so that the dragon heart can only rely on a woman's intuition to run back.

The giant beast didn't seem to want to let go of the thief at all, and even wanted to treat the dragon's heart as a delicious snack, and a roar that shook the sky made the dragon's heart more and more anxious.

And what is worse is that this time the woman's instincts, instead of bringing him the right direction, forced her into a corner, and after she went on a rampage, she found that all around was hard stone, and the only exit was blocked by the beast.

"Up!"

Ryuxin adjusted his breathing, then rested his saber on his chest, and Zuihou rushed directly in the direction of the giant beast.

The giant beast didn't expect the dragon heart to have this trick, and suddenly suffered a big loss, and cut off half of the wings, but unfortunately the dragon heart was not very visible in the dark, so that the saber could not attack continuously, which made her very anxious.

And at this time, the giant beast has obviously been stimulated blood xìng, in which, it has always been the existence of the king, and suddenly someone hurt it, which made it extremely angry, and roared and grabbed the hard stone and smashed it towards the dragon's heart.
