At this point, by drilling,

The new line is connected to the microrobot,

Microrobots also have the ability to turn on the lights after getting enough energy.

And when the lights are turned on,

Yang Meng finally saw the picture sent back,

The various equipment in the pressure chamber are basically similar to those in the air pressure chamber used by his spacecraft.

This situation also confirms one thing,

These metal balls are inextricably linked to the pioneer astronaut.

"But why did this happen!"

"There's lifeforms, there's metal balls, where is she?"

Yang Meng is not clear,

At this time, he could only focus on the door on the other side of the pressure chamber.

When you open the door, you'll find something.

The pressure chamber is the same as the barostatic chamber,

With two gates,

When a person enters the pressure chamber from the outside, the outer hatch closes.

The cabin environment will be adjusted to the same environment as the inside of the metal ball.

Then the inner door opens,

In this way, the entry of outsiders can be ensured.

At this time, the microrobot came to the inner door of the pressure chamber,

Try to use the automatic opening method to drive the inner door,

It can be the same as the outer door, after Xiao Yin's detection and analysis,

The internal automatic opening procedure is also detached from the locking structure.

"If the auto-start program is detached, then there should be a problem with manual opening, and it seems that some brute force will have to be used again!"

Such a thought flashed through Yang Meng's mind,

And the next operation of Xiao Yin also verified his idea,

As the outer door drilling expanded, more equipment was crowded in,

Commonly used wrenches also began to try to unscrew the inner door,

And like the outer door, there was no reaction after twisting it for a long time.

"I can only drill holes!"

Soon the equipment for drilling the hole was ready,

It's just that the drilling process this time is different from the last time.

The outer door has a bowl fastened tightly

No matter how the air pressure on both sides of the outer door changes,

will not affect the safety of the device,

But it is not possible to determine what the air pressure environment on both sides of the inner door is.

However, considering that the air volume space in the air pressure chamber is very small,

In consultation with Xiao Yin,

A small drill is carried out first, and then the expansion operation is carried out.

And after agreeing on the eye-opening plan,

Eye-punching has also officially begun.

When the drilling machine is drilling,

Yang Meng is not idle,

The miniature detector he used, in the barobaric chamber, detected something,

"The screen is on, but there's nothing on it!"

"Huh! The text here."

Under the light of the microrobot,

Yang Meng saw the text on some keys,

These words are in his native language, and he is naturally very familiar with them.

But because of his familiarity, he found that the words on these keys seemed to have some inexplicable changes.

Seeing this change, he thought for a moment and asked Xiao Yin:

"Xiao Yin, have you detected any traces of intelligent programs or control networks in the metal sphere?"

To tell the truth, I've been chasing more with reading books recently, switching sources, and reading aloud with more timbre,.. Both Android and Apple are available. 】

Hearing Yang Meng's question, Xiao Yin immediately responded:

"The existence you said was not detected, it may be that there is a problem with the energy supply, which caused these things to be disconnected!"

"That's it!"

As a pressure chamber to isolate the environment, it is very clean, no matter what

It's not much of a device or an operator panel.

As a result, there are too few clues to provide useful information.

The drill hole continues,

Although the structure of the inner door is thinner than the outer door,

But because there is a limit on the size of the equipment that comes in from the outside,

The power of the drill bit is not great.

But even so, after spending almost seven minutes,

The inner door was finally drilled through,

At the moment when the drill hole was successful,

A strong air flow rushed out of the hole,

This air flow meets the cold air in the cabin,

A distinct column of air was formed.

This air column is somewhat similar to the air flow that comes out of a flat tire.

But the intensity of this air column is far from being comparable to a flat tire.

"Attention, the environment of the pressure chamber is changing drastically!"

"...... under monitoring"

"The pressure value has been determined, and the probe is about to inject air into the capsule according to the final pressure index!"

With the advent of the air column,

The environment in the cabin has become unstable.

Nor can the detection operation be carried out,

At this point, you need to wait for the pressure to equalize before proceeding to the next step.

Fortunately, the detector outside injected gas of the same pressure into the cabin according to the detected pressure data to balance the pressure inside and outside the cabin.

With a large amount of gas injected, equilibrium was reached in less than a minute.

"Detecting the gas environment!"

"...... in Analysis"

It was also when Xiao Yin was analyzing the gas data,

Several microrobots burrowed through the hole. to relink the locking structure behind the hatch,

The inner door opened slowly.

At this time, the small light next to the screen saw that the microrobot opened the inner door and flashed:

"It turns out that this door can be opened,

Then why don't you open the door on the outside floor as well, so that it is easier to get in and out?"

Hearing Xiaoguang's question, Yang Meng shook his head gently,

Although the moment the outer door is successfully drilled, the outer door can be opened,

But for the sake of safety, to protect the clues inside the metal ball,

In the plan I made before, it would be good if I could open the outer door smoothly,

But if you want to make an eye on the outer door, the outer door can't be opened casually.

After all, this is the depths of the ocean,

The detector is just a temporary device,

If something happens to the detector, there may be a flooded sphere.

Thinking of these, Yang Meng briefly told Xiao Guang about Xiao Yin's considerations,

After listening to this, Xiaoguang flickered and continued to ask:

"Wouldn't it be enough to fill the hole that was drilled!"

"It's not that easy, this ......?"

Yang Meng's words suddenly stopped at this point,

The small light on the side immediately noticed this anomaly, it flickered rapidly, and asked:

"What's wrong?"

At this time, Yang Meng was communicating something with Xiao Yin in his body.

Just now,

Xiao Yin analyzed the gas data in the cabin,

If there are humans inside, then according to the normal gas environment,

Its gas composition should be similar to that of the Earth,

Nitrogen in the air accounts for 78%

Oxygen occupies 21%

However, because it is a man-made gas environment, no other noble gases are needed, and the proportion of oxygen can be slightly higher.

And inside this metal sphere,

Nitrogen up to 98%

In addition to nitrogen,

The second most abundant is carbon dioxide.

And in addition to these two gases, there are some other micro

gas measurement,

The composition of these trace gases is very strange.

What caught Yang Meng's attention was that

Ammonia gas is present in these trace gases.

"Xiao Yin, analyze the composition of ammonia gas in detail!"

"Understood!"

With Yang Meng's instructions,

Xiao Yin quickly analyzed the results,

Looking at the list of data analyzed by Xiao Yin, Yang Meng secretly muttered:

"Sure enough, there are corpse ammonia and putrid ammonia!"

Yang Meng is not a professional biochemical researcher.

But the two substances of cadaveric ammonia and putrefant ammonia,

Just from the literal meaning, you can understand its origin.

At this time, the inner door of the barometer has been completely opened,

In Xiao Yin's prompt tone,

Yang Meng looked at the position of the hatch,

Compared to the faint light of the equipment in the pressure chamber,

The environment outside the cabin can be described as pitch black.

……

Although the dark environment is a little unsettling,

But this is an exploration under remote control after all,

Even if there are strange alien creatures inside the metal sphere that humans can't understand,

It is impossible to follow the signal wave to Yang Meng.

therefore

He didn't hesitate at all,

Immediately let Xiao Yin's dispatch detection device enter the metal sphere,

Regarding the situation of the metal ball, Yang Meng can be said to be very curious.

As the lights of the detection robot are turned on,

The darkness in the inner door was instantly washed away,

Yang Meng looked at the outside scene through the light,

On the opposite side of the inner door is a gray wall with a metallic sheen,

The wall is not empty, but marked with the number 3,

"So there are at least three of them?"

"But the data from the previous shock detection shows that there seems to be only one such exit?"

When Yang Meng saw the numbers,

The detection machine has begun to move,

After passing through the inner door, there is a horizontal corridor,

The corridor does not exist in a straight line, but is presented on the screen in a curvilinear structure.

"This should be the main passage inside the metal sphere!"

In previous shock detections, the internal structure of the metal sphere has been basically determined.

Because it's a spherical structure,

So there are three spirals in it.

This spiral spirals out of the center of the sphere.

The end point is to reach the edge of the ball.

At this point, the detection robot follows a spiral towards the center of the metal sphere.

……

Although the outside of the metal ball looks huge,

But the interior space is not as big as expected,

So the detection robot soon encountered the first cabin,

This chamber is on the opposite side of the barochamber.

Under the illumination of the light,

You can see that there is a screen next to the hatch,

It's just that the screen is gray, and nothing is shown.

At this time, the detection light moved to the hatch again,

Through the illumination of the light, Yang Meng found that the hatch did not seem to be closed.

Instead, it left a small gap,

Through the light, it seems that you can see something through the cracks.

"Xiao Yin, I remember that in the previous shock detection data, there was a humanoid thing here!"

"Yes! There's two humanoids in this chamber!"

After receiving Xiao Yin's affirmative answer, Yang Meng nodded and said:

"In that case, let's take a look at what's inside?"

"Understood!"

At Yang Meng's request,

The detection robot car stretched out a device to try to open the hatch,

But maybe it's because the power of the detection machine is too small,

The hatch opens extremely slowly,

Fortunately, the hatch only needs to be opened to a certain extent,

The detection robot can enter it.

"This seems to be a dormitory!"

When he saw the appearance, Yang Meng made a judgment.

There is no high-tech equipment here.

There are only some beds.

It's just that what surprised Yang Meng was that

In this small space, there are twelve beds squeezed down,

These beds are in groups of three, including above, middle and bottom, and fill this small space.

"How can there be so many beds?"

The scene in front of him made Yang Meng feel that something was wrong,

This environment is not at all like that of normal human habitation.

"Where are those humanoid objects in Xiao Yin?"

"Here"

At this moment, a virtual annotation point immediately appeared on the screen in front of Yang Meng's eyes.

Looking along this marker,

In the gap between the metal support rods of the bed, he vaguely saw something,

In the innermost lower bunk, there is a humanoid silhouette.

Because the space is very small

It is inconvenient to detect the machine cart to enter,

Therefore, the robot car raises the lens through its internal telescopic rod.

And by adjusting the light and focus to see what's inside,

In the process of continuous adjustment,

The screen in front of Yang Meng's eyes is between the mold lake and the clear,

In this change,

The scene on a bed was presented in front of Yang Meng,

It was a very simple bed.

There is no mattress on it,

There is only one metal bed board,

There was a man lying on it,

A corpse to be exact,

This corpse was dressed in a one-piece gray garment,

This kind of clothing is close to some kind of rubber material,

And the reason why it is said to be a corpse,

It's because of this man, in a state of semi-decay,

The limbs have a large number of corpse spots clotted by blood.

In the place where the one-piece leather jacket was wrapped, large and small bulges also appeared.

As for the face, it is an indescribable state of meat lake.

In short, this is a certain state of corpse that is difficult to appear in the environment on earth.

It's as if a corpse that is about to decay has for some reason stopped the normal corpse change.

This kind of image made Yang Meng a little uncomfortable, he shifted his gaze and asked Xiao Yin:

"What about Xiao Yin's other corpse?"

"Here!"

Hearing Yang Meng's question, the exploration car adjusted its perspective,

Another corpse is shown in the video,

And the condition of this corpse looks very similar to that of the first corpse.

It is impossible to see clearly and to directly identify gender.

"Xiao Yin, send out a micro-machine to collect genes from above!"

"Understood!"

With Yang Meng's instruction issued,

At the back of the exploration vehicle, a small flying device was released.

Flying in the direction of the corpse, the small device landed on the corpse like a fly,

"Xiao Yin, is there a way to tell when they died?"

"Due to environmental factors, it is not possible to determine the time of death?"

"However, according to the degree of environmental attachment of cadaver ammonia and putrefaction ammonia, it can be judged that these people have been decomposing for at least more than that

Six months!"

Hearing such a judgment, Yang Meng nodded slightly,

Neither he nor Xiao Yin is good at forensic criminal investigation.

Therefore, he did not ask Xiao Yin about the cause of death of these corpses.

After all, when he left Earth, the human aerospace engineer would not have expected that he would encounter the corpse of a human,

Therefore, this technology is not equipped either.

At this time, the small flying device has retrieved samples from the corpse, and these samples will be sent back to the spacecraft for examination.

With no other clues, the rover left what looked like a dormitory room and continued to go deeper along the spiral metal passage.

And with the rover, approaching the metal sphere, soon some corpses appeared in the passage.
