It was an open, huge underground cavern. From the perspective of the robot dog that first reached the edge of the underground cavern, it takes about 20 meters to reach the top of the cave and nearly 50 meters to the opposite cliff.

Of course, the cliffs on the opposite side are not flat, they are also full of bumps. The distance of more than 50 meters is calculated based on the closest location.

I don't know how many meters away I am. Although the robot dog is equipped with a laser rangefinder, the environment here is too complicated, full of bumps and bumps, and twists and turns, and a laser rangefinder that can only measure straight-line distances is not easy to use here.

At present, with the ability of night vision devices, I can only barely see that there seem to be many cracks underneath. Some of them are wide and some are narrow, and they are equally curved, some leading to the rest of the world, and some to the deeper underground.

The cave was humid and stuffy. Air composition analysis shows that the oxygen content here is extremely low, and there are many toxic and harmful gases such as sulfides and chlorides.

During the observation, the rest of the robot dogs also came to the edge of the core cave through different passages, providing different angles of images for the people in the temporary headquarters from different perspectives.

At this moment, looking at this underground cave that may have existed since ancient times and has been isolated from the outside ecosystem for an unknown number of years, looking at the scene of different shapes and colors under the night vision device, full of mystery and antiquity, everyone fell into silence.

It is very likely that this is the birthplace of phobic bacteria. Here, it is highly likely that there is an independent ecology independent of the external ecosystem.

Once upon a time, the ancestors of the phobic fungus were isolated here from the outside world. Over the course of time, the cave may be deeper into the ground, or it may be slightly closer to the surface. Its internal environment, internal pattern, structure, etc., may also change countless times. There may be earthquakes, there will be underground rivers pouring in, there will be different gases flooding in between, and every change will be a disaster for the small ecology that exists inside.

But the phobic bacteria that lived in it survived and survived every disaster. They have spent a long time in continuous evolution, and under the command of the "Lou Shen", they have once again gained the opportunity to connect with the outside world.

What exactly is Lou Shen? Where exactly does it come from? How did it get into this subterranean ecology?

Could it be that Loushen is also an ancient life, and in the long process of evolution, it has evolved wisdom and the ability to command phobic bacteria? In other words, is it a symbiotic relationship with phobia?

Just like the legendary wolf and embarrassment, the wolf provides force, provides action, and embarrassment provides intelligence, and the two coexist in order to obtain more survival resources - the survival mode of the wolf and the embarrassment has long been falsified in the face of modern technology, but this symbiosis mode is not uncommon in nature.

So, will Lou Shen and phobia be this kind of relationship?

This is the place where the phobia was born, is it the place where the god of the building exists?

Putting away a little reverie in his heart, Lu Ming once again focused his attention on the observation of this underground cave.

At this moment, under the photography of dozens of robot dogs, although this underground cave is huge, most of it is still clearly explored.

There are six directions, front and back, left and right, up and down, and there is only one "down", which cannot be found out because it is too deep. The remaining five directions have detailed video materials.

Although the scene here is strange and mysterious, after looking at it for a long time, you can find that compared with the rest of the underground caves and caves, there is not much difference here.

The only thing that may be different, and the only thing that still exists unknown, is where the "Lou Shen" may exist, and only the bottom is left.

There, even if the robot dog's shooting ability is turned on to the maximum, it is still not clear to see.

Those cracks, those tortuous passages, are like leading to hell, and people are inexplicable in their hearts just by looking at them.

But......

The terrain here is too complicated, and it is too deep there, and with the ability of the robot dog, there is no way to go down.

"Can you transform the robot dog and go down with things like rock climbing, abseiling, or just fly it with a drone?"

The engineer pondered for a long time before shaking his head with shame: "The terrain is too complicated, with the current technology, it can't be done." ”

Zhang Dingshan knocked lightly on the table: "Since you can't do it, then throw these robot dogs down." As much as you can shoot. ”

Lu Ming knew that Zhang Dingshan was planning to launch a "suicide investigation".

Robot dogs can't climb or abseilate, or fly down to the bottom, so they just let them fall or roll down. Although this is destined to cause them to fall, there is always something to be captured in the process of rolling or falling downwards without being directly destroyed.

The price is not insignificant.

At the moment, the robot dog that explores the underground cavern has been specially customized and modified. And, even if it is a mass-produced model without special customization and modification, the cost of such a robot dog is at least one million.

Now, the cost of this robot dog has climbed to at least more than 5 million per unit.

Twenty units is at least 100 million.

Now, Zhang Dingshan wants to throw this equipment worth at least 100 million yuan directly.

Even if Lu Ming has joined the second team of action at this moment, he can mobilize a huge amount of resources that were unimaginable in the past, and he is a little secretly frightened at this moment.

On the other hand, He Wei turned a blind eye to this.

"I'm still a little bit of a child." Lu Ming secretly smiled bitterly in his heart: "Compared to this matter, 100 million is really nothing." ”

In the face of Zhang Dingshan's order, the engineer's expression turned pale instantly, and he seemed to be shocked by Zhang Dingshan's generosity. It took him a moment later to react, and he replied with a little awe.

Twenty robot dog operators issued corresponding orders at the same time under Zhang Dingshan's orders. So in the next moment, on top of the twenty screens, the originally stable picture vibrated and tumbled violently at the same time.

Lu Ming seemed to see the picture of twenty expensive robot dogs tumbling down in the underground cave, constantly colliding with the rocks. This made him grin and subconsciously feel a little distressed.

The shock and fall of the screen lasted only a few seconds, and then one of the monitors turned black.

"The communication cable was torn off."

The operator observed for a moment and gave an answer.

The length of the communication cable was sufficient, but now it is being torn off, most likely because the cable tray is stuck and no more cables can be released.

In such a complex environment and with such strong electromagnetic interference, the wired cable was torn off, which meant that it was impossible for them to communicate with the robot dog. Even if it could still shoot anything, it wouldn't make sense.

After that, one after another, the picture began to go black.

Every blackening of the picture means that a robot dog is completely destroyed. And their destruction is only exchanged for a chaotic picture that is as short as a few seconds and as long as a dozen seconds.

In less than half a minute, nineteen of the twenty video screens went black. Only the only one left is still on.

It's a lucky robot dog. Even if it fell and hit for more than 20 seconds, it could not be completely destroyed, but it still maintained the ability to communicate with the outside world.

But the operator tried to do it twice, and finally shook his head: "I can't move." ”

The picture presented at this moment is a dark and deep crack that seems to lead to the ground.

Perhaps humans know more about space than about the interior of the earth. At this moment, this crack in front of people seems to declare the infinite mystery hidden deep underground.

Zhang Dingshan nodded: "Call up all the pictures and check them frame by frame." ”

Twenty robot dogs filmed a total of about five and a half minutes of video during the fall. At this moment, these videos are being carefully observed by people with an unprecedented solemn attitude, carefully searching for valuable information that may exist in them.

But most of those images are so ambiguous and distorted that you can't tell what you're shooting.

Under the violent movement and concussion, even a small stone can be twisted into a monster. Therefore, people had to introduce another special picture analysis system to restore these distorted pictures one by one in combination with the movement state of the robot dog lens at that time.

It took a couple of hours. It was only after this that people finally saw the steep rock faces, the strange twisted stone pillars, the deep caverns, and the dark cracks that were still bottomless.

These scenarios, while peculiar, are clearly of little value.

Just when Lu Ming was a little disappointed in his heart, He Wei suddenly screamed.

"Captain, Lu Ming, there's a discovery here!"

Lu Ming immediately turned his head to look, and the whole person was instantly frozen.

At this moment, in the monitor screen, the main body is still occupied by a pitch-black crack, leading to the unknown depths of the ground. But at the edge of the frame, something is half exposed.

It is in mid-air, and it is clearly visible that it is not in contact with the rock face. It is cylindrical as a whole, about a dozen centimeters in diameter, slightly curved, and on top of it, there seem to be many thin flagella or cilia or something like that.

Although he could only see part of it, Lu Ming immediately recognized it.

During this period of time, Lu Ming was too familiar with this kind of thing. Beneath the microscope lens, in the middle of the screen, he didn't know how many times he had seen it.

It's a phobia!

However, the phobia is obviously a microorganism, how can it be so big! How could it be captured by the lens of a robot dog?

The lens of the robot dog is not a microscope!

It has a diameter of more than ten centimeters and a length of half a meter or even a meter...... Giant phobophilia?

How is this possible?!

In particular, this thing seems to be suspended in mid-air? How can this thing fly?

At this moment, Lu Ming even had a feeling that the three views were subverted.

"Do you have any more video material?"

Nearby, the engineer was sweating on his forehead. Under his command, a dozen operators were scrambling to check the rest of the footage. After a while, he wiped his sweat and said, "Only Robot Dog 17 captured about a second of footage about this thing." After that, Robot Dog 17 fell into that crack in the ground. ”

"Bring the original picture."

This picture, which is only 970 milliseconds long, was presented in front of Lu Ming. Clicking the play button, Lu Ming vaguely saw a shadow fleeting in the violently shaking picture.

After slowing down, Lu Ming saw a section of the "giant phobic bacteria" slowly poking out from the edge of the picture, slowly extending, and then, with the change of shooting angle, it was slowly blocked again, and finally disappeared.

"Is it a problem with the angle, or is it this thing...... Moving? ”

The engineer said, "It's determined that it's a problem with the shooting angle. The thing didn't move. ”

Lu Ming looked at Zhang Dingshan and He Wei, and saw that their expressions were full of solemnity.

Is this thing alive or dead?

If it were a living thing, how did this thing come about? What kind of life is it? Is it the god of the building?

Could it be that the relationship between Loushen and the phobia is similar to the relationship between the queen bee and the ordinary bee, or the relationship between the queen ant and the ordinary ant?

In this case, there seems to be an explanation why this giant phonosaur is so huge.

In nature, queen bees and queens are also much larger than their counterparts.

It's just that this phobic fungus "fungus king" is too much bigger, right?

Is it because it is so large that it has intelligence? Conscious? Can you command ordinary phobia?

Or...... It's a dead thing, but it looks like a phonophore, but it's actually made of rock or something else, like a sculpture or something?

But it is clear that such a thing, which can be determined to be exactly the same as a phobia bacterium based on only a part, cannot be naturally generated. So, who carved it?

If it was an ancient man, then, in the era when there was no microscope, how did he know what the phobia looked like?

At this moment, many conjectures were chaotic, and they filled Lu Ming's mind in an instant. But he soon realized that there was no point in such speculation.

At the moment, all you know about this thing is this video footage of less than a second. However, without sufficient information, no guess can be made.

The probe had to be done again, and more information about this thing had to be obtained.

But...... I am afraid that relying on robot dogs will not work. Existing technologies cannot detect under the premise of such a complex environment.

He Wei took a deep breath and stood up.

"I'll go in and I'll have this thing for a while."

Lu Ming subconsciously wanted to stop it.

In any case, the situation is unclear at the moment, and it is too dangerous to face a potentially new and unknown life.

But before Lu Ming could say his words, he saw Zhang Dingshan nodding solemnly, and directly agreed with He Wei's suggestion.
