He put on gloves and caught the bright spot, and gently tore it open, feeling a bit like a mushroom, containing a trace amount of water, and itself containing fluorescent substances.

And it's not necessarily a seed, it seems that it's already a strain that has grown to a certain extent, looking for a new place to put down.

Just when everyone wondered if this plant was poisonous or not, caution suddenly became meaningless, and a breeze blew from the darkness, suddenly bringing countless glowing dots, which instantly filled the surrounding space.

There was no point in dodging, there was no way to dodge, and many small umbrellas had landed on everyone's skin, but they didn't immediately trigger any uncomfortable reactions.

Lynch had already taken off his gloves and crushed another one: "It's non-corrosive, it's not toxic on contact, this thing looks like some kind of fungus that glows." ”

But for the sake of insurance, the expedition team still wore masks, such a tiny thing is easy to suck into the lungs.

Pei Xinhui was puzzled: "The oxygen content and purity here are much higher than an hour ago, and the wind is blowing just now, which is similar to us approaching a big forest." ”

Everyone was silent, and Chen Kaixuan said at this time: "It's time to take a break, most of our in-depth time has passed, everyone eat something to maintain their strength." ”

Su Ting also crushed a small point of light at this time, and after pondering for a while, she said, "I have a feeling that the light we have been chasing is probably emitted by this kind of small thing." ”

Roque felt incredible: "If that's the case, then I'm afraid that there will be this thing all over the front, and it's simply a mushroom world." ”

Chen Kaixuan asked Lynch: "Do you say that this fungus plant produces a lot of oxygen?" ”

Su Ting interjected: "The survival of the animal and plant kingdom is relatively balanced and interdependent, and I am more curious about what animals and plants need such sufficient and high-purity oxygen in such a deep place underground." ”

"It's hard to say, plant photosynthesis can be carried out above the lowest light saturation point, it doesn't have to be direct sunlight, scattered light is fine, even light is fine, some bacteria and bryophytes can produce oxygen in low light, but it's usually not enough for their own consumption," Lynch said. ”

"We breathe so much oxygen that only greenery can provide. However, the ecology here is very special, this fungus has not been found on the surface of the earth, and perhaps in this environment, this fungus can use the light it emits and photosynthesize to produce a lot of oxygen. ”

Su Ting asked: "You haven't explained my question yet, why do you need a lot of pure oxygen here?" ”

Lynch hesitated: "It's hard for me to answer this, maybe it's some coincidental factor, not necessarily for the sake of ecological balance." ”

Wu Bo said: "The lack of light in the ecosystem here was originally incomplete, but this plant emits its own light and makes up for this shortcoming, which can be understood as self-compensation in ecology, and it is actively moving closer to the production of oxygen." So there must be other plants and animals here that need oxygen. ”

Pei Xinhui also said: "Of course, it is impossible to prepare such a large amount of oxygen to welcome us. ”

Before going underground, they had analyzed the causes of the death of the previous expedition many times, envisioned various possibilities, and even consulted the navy, but the navy had nothing to say.

At that time, their analysis was more inclined to geological disasters, and the two most likely scenarios were the lack of oxygen or poisoning due to air quality problems, and the other was the instability of the underground structure, which suffered an accident such as a collapse.

Now, along the way, not only is the geological structure stable, there is an underground river with abundant water, but now there are also luminous plants and more and more abundant oxygen, which is unexpected.

The second point is premature, but the first assumption is certainly wrong at the moment.

In such an unexpected situation, the focus of work must be adjusted according to the actual situation, so the next safety point is naturally to focus on preventing biological invasions.

And what would an animal that could use plants to create oxygen in this environment?

Almost all of them were aware of the seriousness of the problem at the same time, and the few agents who were mainly responsible for security began to check their equipment again after eating.

During the half hour of the break, I didn't feel the wind anymore, and there was no flash of light floating back on the umbrella.

In such a closed space, it is understandable that the underground river brings some breezes, but how is the wind blowing from the space formed? How does the air move?

No one asks such questions anymore, the expedition team is here to investigate the problem, and it is a waste of energy and time for them to sit back and talk about it, what they should do is to act and verify.

Fourteen hours had passed, and the expedition began to get tired, and rested for two hours as planned, and only had to go on another six hours before reaching the farthest point of the expedition, when the survey rested for two hours and then began to return.

The Ministry of the Dark World also made up its mind at that time, and decided to investigate the underground world in batches and steps, but this time it was only tentative, and naturally put stability in the first place.

After resting, the whole team strengthened their vigilance, and after walking forward for about half an hour, there was a new discovery!

They found clusters of snowflake-like plants on the rock wall, which must have grown from the glowing seeds they had just taken root.

The snowflakes are not high, only about two centimeters, and they grow on the rocks like white glowing moss, and from a distance they look like snowflakes falling on the rocks.

At first, the snowflakes were scattered, and the further you went, the denser they became, and when you stood in the darkness, it was like a frosty wind blowing from the space, gradually freezing the cave from far and near.

They became more and more careful, and after half an hour of walking, the rock walls and the ground were already covered with this kind of snowflakes, and it was as if they had stepped into a world of completely white ice and snow.

The snowflakes emit a faint white light, although it is dim, but it basically illuminates the surroundings as if before dawn, and everything can be seen clearly in the hazy and hazy!

The top of the stone wall where they were already twenty meters high and fifty or sixty meters wide was already twenty meters high, and it looked like a huge auditorium as far as the eye could see.

The light mist they had seen from a distance before should be here, although it seemed to be a little more spacious and brighter inside, but it should only be here as far as the eye could see at that time.

And standing here and looking farther away, it seems to stretch all the way to the endless distance, which is a world of white light bacteria.

Lynch has been very excited after seeing the luminescent mushrooms, these luminescent plants are a major discovery for him, and even for the entire human race, and they have very far-reaching practical value!

If this fungus were to be sown on the moon and Mars, you can imagine what kind of strategic significance it would be.

He had already taken a lot of samples and carried them on his back, and he had been walking in the front of the crowd, when he turned around and said with a smile: "Who said just now that this is a town, come out and slap your face." ”

In the faint white light, his smile became a little blurred, and then became more and more out of shape, until finally his head exploded like a watermelon, and the whole person fell to the ground!

Not only was he slapped in the face, but he was also knocked off the head!

In the face of the sudden strange change, even the highly trained elite operators couldn't react for a while, and before they could make a move, the two operators in front of them fell silently!

The rest of the operators blew up and quickly dispersed, but in the white light, they didn't know where the attack came from, there was no fire, no sound, they couldn't determine the location of the other party, and they didn't even know what weapon the other party was using to attack!

Luo Kra and Song Shijia retreated and blindly strafed the air, but soon the two of them staggered and fell to the ground!

The glimmer of light in the cave completely exposed the remaining six, and they gave up firing back and retreated with all their might!

But the speed of the opponent's attack was very fast, and he quickly followed, and returning back the same way was already a dead end, Chen Kaixuan pulled Su Ting and ran to the underground river!

Only one operator followed behind them, and when Su Ting turned back again, he had already fallen, and then Chen Kaixuan also stumbled, but he pushed her hard before falling, and Su Ting fell into the underground river with a thud!

The river water in April was cold and biting, Su Ting struggled to surface, wanting to return to the shore but couldn't do it, the underground river has become turbulent here, and she followed the river all the way down!

After being washed out for a few hundred meters, she encountered a waterfall with a drop of about 20 meters, and the defenseless Su Ting fell, and the huge impact instantly knocked her out!

I'm afraid it won't take more than a minute to faint, otherwise she would have drowned here even if she hadn't fallen to her death!

The river formed a small alluvial pool here, which saved Su Ting's life.

After Su Ting woke up, she swam gently to the shore, but she didn't dare to go ashore immediately, and soaked in the cold water for half an hour.

She didn't dare to return to the light of the snowflakes, the power of the opponent's attack was so powerful and unpredictable, she would soon die once she appeared.

That kind of snowflake obviously doesn't like humidity very much, and the surrounding area of the underground river is relatively rare, so it is particularly dark, which also provides convenience for Su Ting to hide.

After gradually learning about the environment, Su Ting decided to climb up the edge of the waterfall and then go all the way back along the underground river.

This was probably the only way out at the time.

The rock wall was very slippery, Su Ting carefully chose the path, groping for several hours before climbing the waterfall, during which as long as one stumble and then fall, even if it was only injured and fractured, it would be difficult for him to come back alive.

The usual rigorous climbing training saved her life at a critical moment.

After going up, she moved very carefully along the river, which was a high-risk area, and the other party was likely to be on the shore.

She was like an alert beast, only advancing two or three meters a minute, and it took more than three hours to get back to where she fell into the water.

By the glimmer she didn't see the corpses of the operators, but in the distance she could see Lynch's blood spilling on the alabasters on the ground, red and bright, and the bodies were gone.

Su Ting knew that it was futile to do anything with her own strength, and now all she could do was to escape and tell the people above what she saw, lest they blindly follow up the rescue and be ruthlessly slaughtered again. , you are lonely, the young lady warms you with a movie
