Although the metal sphere looks as if it is a whole body,

But after all, the technology to build metal balls came from humans.

The probe searched for a moment,

Or found the hatch to enter,

And this hatch is located where the metal ball comes into contact with the bottom surface under this space.

However, in the face of such an easy hatch to find,

Yang Meng frowned, as if he was thinking about something,

Xiaoguang's vision on the side was looking at the screen, and seeing that Yang Meng had been silent, he turned his vision to Yang Meng:

"Is there something wrong?"

Hearing Xiaoguang's question, Yang Meng nodded slightly and said:

"The detector is so close to the metal sphere, if she's inside, the artificial intelligence she has should be alerted!"

Yang Meng's statement made Xiaoguang flicker slightly:

"Or maybe it's just an automated device here,

Isn't the ship running automatically while you're sleeping?"

Xiaoguang's words made Yang Meng groan for a moment, and then shook his head gently,

Although in the course of the astronautics,

Most of the time, the spacecraft is in a state of automatic flight under program control.

But in the face of a complex cosmic environment,

His dormancy will still be interrupted.

And the environmental complexity index on the planet is far greater than that of space.

Especially in an environment like Ross 128b,

As a pioneer astronaut, you will not be able to react to the approach of other unknown devices.

"Maybe she hasn't reacted yet!"

Yang Meng had such a guess in his heart,

"Or maybe this isn't where the pioneer astronaut sleeps?"

And the little light on the side seemed to see Yang Meng's entanglement, and said with a flash:

"Since this is the technique used by your people, wouldn't it be clear when you enter and take a look?"

Hearing such remarks, Yang Meng was not entangled in anything,

Observing this hatch,

At this time, the lights on the detector are back on,

By the light,

Yang Meng found that this hatch was different from the hatch used by space manned equipment.

Its hatch is mainly an embedded structure,

There are no hand tools that can be used at a glance.

He searched and analyzed for a while,

found that it is not easy to open the hatch,

The probe does not have the equipment to open the hatch.

After all, the detector used at this time is only an underwater detector with a relatively simple structure.

It does not carry other complex mechanical functions.

"Actually, you can knock it the old way."

"But if she's inside, the knock might make the metal ball structurally vulnerable!"

Thinking of this, Yang Meng looked at the metal ball on the screen and gave instructions to Xiao Yin:

"High-precision sonar detection receiver transmitter turned on!"

"Understood!"

Although tapping is the best option, and it is also the easiest to see the structure inside,

But this is not space after all,

It's an underwater environment,

Water is not like space, there is no sound wave transmission medium, you need to lie directly on a large object to strike.

In the ocean, water is a good conductor of sound wave transmission.

In a tense history of the earth,

Inside the submarine in the ocean, the sound of the cup falling and hitting the floor may also cause the submarine to reveal its position.

At this point, the detector is so close to the metal sphere,

It may be possible to detect slight movement and determine something.

In addition, because the metal sphere is in the depths of the ocean at this time,

Although it is only 160 meters away from the sea,

But the pressure generated by the seawater can already be dangerous to humans who are not wearing any protective equipment.

In such an environment,

The compressive structure of the metal ball is in a very delicate state.

If you accidentally knock a metal ball out, it can lead to some dangerous consequences.

……

Some thoughts flashed through Yang Meng's mind,

At this time, Xiao Yin received Yang Meng's instruction,

Hold the detector close to the metal sphere and listen to the movement on it.

"Several sound data sets found!"

"Analyzing!"

……

Xiaoguang on the side saw Yang Meng's series of instructions, and asked in a flash:

"Can this detect the inner structure inside?"

Yang Meng, who was analyzing the internal voice with Xiao Yin, nodded when he heard such a question:

"Almost!"

Speaking of this, Yang Meng glanced at Xiaoguang,

During this period of underwater probe detection, he found that Xiaoguang's understanding of underwater detection technology was almost zero.

So he subconsciously asked:

"You don't seem to know much about the underwater environment!"

"We have lived on land since the beginning of primitive life, and the proportion of ocean area on our planet is not high in the first place......

"That's it!"

Yang Meng nodded, not thinking much about this issue,

Instead, continue to look at the sound waves that the detector found during this time.

In this gap between his conversation with Xiaoguang,

Xiao Yin has analyzed most of the types of sounds,

"Most of these sounds are background noise from fixed equipment!"

"Didn't you find the sound waves of moving objects?"

"Not yet."

Hearing Xiao Yin's analysis,

Yang Meng could only continue to let Xiao Yin monitor.

At this time, Xiaoguang on the side found something through the split screen, and woke up:

"The windless belt has reappeared!"

And hearing the voice of the little light,

Yang Meng turned his perspective back to the pneumatic detector in the sky,

In order to ensure the concentration of signals and reduce discreteness,

The entire pneumatic detector is suspended above the underwater detector.

And in the footage of the aerial probe,

The surrounding is cloudy, and the waves below are monstrous,

But at the end of the sea level, you can see a ray of light slowly coming in this direction.

"It seems that there is a certain pattern in the changes of the windless zone on this planet!"

With the advent of windless belts,

The polypore fungus in the sea rises again,

And seeing this phenomenon,

Yang Meng suddenly thought of the windless belt picture he had seen before,

It's not just this one polypore in the ocean.

There are other similar creatures that float up and down,

"What if there were such metal balls on them?" Yang Meng's expression moved slightly:

"Maybe you can find another metal ball to probe it into!"

Thinking of this, he asked Xiao Yin:

"How many other underwater detection devices are there on Xiao Yin's pneumatic probe?"

"Two more on standby, three on standby!"

"Wait for the windless to bring it in, lock on a large polypore fungus, and deliver it for new detection!"

"Understood!"

The windless belt moves very fast,

Soon the location of the probe became sunny again,

A large number of polypore mushrooms emerge from under the ocean, bathing in one of the few rays of sunlight.

At this point the probe moved to a new one

on polypore,

As with other polypores,

This large assemblage of microorganisms also has a yellowish-green color.

The detector above the polypore, which was just floating and not releasing any device, seemed to be waiting for something.

Because the night hemisphere and the day hemisphere are extremely cold and hot, the upward circulation caused by it has no windy belt, and the change disappears quickly.

It didn't take long for the black cloud wind to reappear,

The polypore fungi in the sea have dived,

And when the wind comes,

An opening appeared under the pneumatic detector, and something like a bomb torpedo was dropped from the detector.

……

Previously placed underwater probes,

Still watching, the metal sphere inside the polypore has not yet detected a moving object in the metal sphere.

And the new detectors,

has approached a new polypore,

This polypore is a bit larger than the previous one, and the wake behind it also has heat flow and urea.

For this case,

Yang Meng has already figured it out in the last polypore,

Like sponges, the polypores of this planet are filter feeders.

They filter nutrients from the sea through ocean currents,

And the wake he detected was also its metabolite.

Although the temperature of the wake and the concentration of urea are somewhat unreasonable,

But this is an alien planet after all,

It's also normal for some things to break through the common sense of human cognition.

Because it's wrapped in a huge sponge,

In addition, the ocean current running through the hole above will produce noise, and the detector will not be able to determine whether there is a similar metal sphere inside.

I can only let the detector find a hole to enter again.

As the saying goes, once born, twice ripe.

Soon the detector discovered:

"There's a similar metal ball here!"

Seeing the image from the second detector,

Both Xiaoguang and Yang Meng showed doubts,

The metal ball on the screen is very similar to the previous metal ball.

If there's anything different,

That is, the micro-engraving number outside the metal sphere is different.

Originally, it was not understood what the micro-engraved number with numbers on the metal ball meant.

But after discovering a second similar metal ball, Yang Meng secretly muttered:

"There should be more than two such devices!"

"If there is more than one such device,

So what was her purpose in building the metal ball, and where was she?"

"That one of your people is strange!" The small light on the side flickered and said when Yang Meng was thinking about the problem.

And hearing Xiaoguang's comment, Yang Meng also agreed,

The behavior of the pioneer astronaut was indeed beyond his comprehension.

"As a pioneer astronaut who has lost contact, but left such equipment on this planet,

She's clearly here,

But why don't you communicate with the Earth?"

Yang Meng couldn't understand,

Although the pioneer astronauts, far from the earth,

has lost almost all restraint and help,

The moral laws of the earth and the visible material resources,

Since the pioneer astronauts left the solar system, access has been difficult.

But among the sixteen pioneer astronauts who left Earth, in addition to the astronauts who went to the Ross 128 system,

The other pioneer astronauts faithfully traveled their responsibilities.

Even the biggest thought in his heart is to return to the earth,

He couldn't figure it out,

This one is in Ross 1

The pioneer astronaut in the 28 galaxy encountered something that caused him to behave incomprehensibly.

"Looks like the best way to solve this puzzle is to go inside a metal orb!"

Thinking of this,

Yang Meng already has some decisions in his heart,

If there was only one metal ball in the ocean, there was probably a pioneer astronaut in it.

In the face of this situation, Yang Meng's detection behavior must maintain a cautious and conservative manner.

After all, human beings are very fragile,

If his reckless exploration caused an accident to the pioneer astronaut, he would regret it for the rest of his life.

But now,

It is speculated that there may be more than one such metal ball,

Yang Meng's detection method can be more adventurous,

However, before carrying out risky detection behavior, for the sake of conservatism, Yang Meng let the probe in the air release an underwater detection device.

Previously, through the experience of two windless zones, Xiao Yin analyzed the upward movement paths of different polypores and determined the location of other polypore.

Therefore, even if the polypore has descended to a certain depth in the ocean,

But the third detector still found a new polypore.

And inside this polypore:

"Sure enough, there are metal balls!"

Looking at the metal balls on the screen, which were very similar to the previous two, Yang Meng finally made up his mind:

"Xiao Yin, have you detected a moving object in the two metal spheres before?"

"No moving objects detected!"

Hearing Xiao Yin's answer, Yang Meng directly ordered:

"Give way to the detector near the first metal sphere and perform percussion detection!"

The structure of the detector in the water cannot, like the impact detector in space,

By carrying a violent impactor, the shock wave can be transmitted to the entire small celestial body, so that the internal structure of the entire small celestial body can be detected.

Underwater detectors are already small,

You can't carry such a ferocious device.

Although there is no impact device,

But there are still micro-robotic arms on the detector.

……

At this point, on one screen, the metal ball is getting bigger and bigger.

Until the end covers the entire screen.

soon

underwater detector,

Tightly attached to the metal ball,

Stretched out a miniature robotic arm,

Under the control of Xiao Yin's program instructions,

The robotic arm does not open and close the metal ball to tap on it.

In the water, it is very difficult to hit things with a hammer.

And the end of the robotic arm has been unfolded,

There was something like a sucker,

It's just that most of the suction cups used in life are rubber products.

And the material of this suction cup is made of metal.

The robotic arm pressed the metal suction cup against the metal ball.

Then the visible vibrations are transmitted from the suction cups.

Originally, this technology was only used to climb rocks in the sea after an earthquake.

But who would have thought that one day someone would use him to shake something else.

……

As the shock wave spreads across the entire metal sphere,

It's like a B-ultrasound-like picture,

Through Xiao Yin's image simulation program, it is presented little by little,

Under the metal sphere,

There is an airtight layer cavity structure,

The cavity is not completely hollow,

Rather, there are a large number of metal structures connected by the inner and outer layers,

The shock wave continues inward through these structures.

Finally the room appeared below,

And when Yang Meng saw the shock in the room, he returned to the image

, even as a professional astronaut, it is difficult for him to remain calm,

At this time, because he saw the humanoid structure,

And there is more than one such "person".
