It is even said that in the face of external dangers,

The oceans will leave the seeds of life for a planet,

The earth has experienced several mass extinctions,

Whether it's a meteorite impact or a ray burst released by a stellar explosion,

Under the protection of the oceans, the possible survival of life will be greatly enhanced.

"So what's in the ocean of Ross 128b?

Could it be that she was hiding in the sea?

But the trail ahead ......"

When he heard Xiao Yin report to him that a weak signal was detected in the ocean, his heart was full of complicated emotions,

However, as a professional pioneer astronaut, he quickly calmed down.

"Xiao Yin, can you analyze the meaning of the weak signal?"

"Analyzing......

Hearing Xiao Yin's reply, Yang Meng nodded silently,

Although the cluster signal on the Earth side has just reached the planet Ross 128,

Coincidentally, an unknown signal appeared on that planet.

However, when human beings are exploring the universe, they have caused some misunderstandings more than once due to various coincidences and misunderstandings in the universe.

For example, when humans discovered pulsars in October 1967 at the famous Cavendish laboratory,

Mistook this neutron star, which has a very regular electromagnetic signal, for an alien signal.

And in 1998, Australia's Parkes radio telescope discovered extremely regular, and sometimes natural space signals.

A large number of researchers have invested in this research.

In the following 17 years, researchers even published hundreds of papers in order to study the signals of this unknown extraterrestrial civilization.

As a result, countless masters, doctors, and even professors have been created.

One day, however, such an important signal disappeared,

After the researchers' painstaking search, it was finally found that it was a microwave oven in the laboratory...... After 17 years of frequent use, it's finally broken!

As mankind enters the information age, a large number of satellites, a large number of electronic products,

Radio telescopes, which detect light blue water droplets in countless blue seawaters, have caused a great problem.

Things that often misjudge make human beings extremely cautious about the appearance of abnormal signals on a planet.

Therefore, although there is an abnormal signal on the planet Ross 128b,

But with a rigorous attitude, Yang Meng still has to eliminate other distractions first.

After all, there are countless things in nature that cause electromagnetic signal anomalies.

Large-scale geological events, such as earthquakes and volcanic eruptions, can cause electromagnetic anomalies.

Yang Meng was looking at Xiaoguang's analysis results,

If the electromagnetic signal on Ross 128b was generated in an unnatural state, then he would have to turn around and go back.

After waiting for a while, Xiao Yin's answer made Yang Meng fall into a difficult situation.

"Signal analysis matching is not possible!"

"Yes!"

"No matching frequency bands were found in the database!"

Such an answer made Yang Meng have some doubts,

Since humanity left the solar system and entered the interstellar age,

There are very detailed data for the detection of various celestial bodies.

Whether it's a star, or a gas giant, or a planetary moon asteroid,

The natural electromagnetic signals that may be generated on these celestial bodies have been observed and recorded in detail.

In addition to these celestial bodies,

Fast radio bursts in the universe, pulsed signals from neutron stars, jets from black holes,

Humans have observed it, and it can be said that most of the naturally occurring electromagnetic signals have been seen by humans.

"It seems that to a large extent, it is ruled out that this is a naturally occurring electromagnetic signal!"

"So what's next!"

Thinking of this, Yang Meng asked Xiao Yin:

"How long will it take to catch up with the ship at the end of the trail?"

"It will take 39 hours to speed up at the moment!"

Hearing such an answer, Yang Meng groaned for a while, and then asked:

"How long will it take for an unknown spacecraft to enter observable range?"

"It is expected to take another 18 hours ......"

Seeing the spaceship that is about to catch up with the wake shot,

Yang Meng didn't think about giving up the chase,

Although the anomaly on the planet Ross 128b today,

may indicate that the end of the trail is not the pioneer astronaut she knows,

But for the sake of insurance, Yang Meng decided to continue to catch up.

……

Time continues to pass,

Yang Meng thought that his chase would go smoothly,

But I didn't expect something unexpected to happen,

After leaving the Ross 128 system,

Because there is no interference from galaxy dust,

entered the stage of linear acceleration and entered the stage of maximum acceleration that a human spacecraft can withstand,

After all, the acceleration that people and the equipment on the spacecraft can withstand is very limited.

And the spacecraft he was flying in was theoretically not much different from the spacecraft of other pioneer astronauts.

When a spaceship reaches the limit of acceleration,

The ships pursued later cannot exceed such an upper limit,

If the initial velocity of the two is the same, it will be difficult for the following spacecraft to catch up with the previous spacecraft maintaining the same acceleration.

Thankfully,

At the beginning, in order to catch up with the wake, Yang Meng used a large orbiting detachment speed.

In terms of initial velocity, it is higher than the initial velocity of the wake calculated by Xiao Yin.

Therefore, although the maximum acceleration they possess is similar,

But the Boundless Oriental that Yang Meng was riding was still getting closer and closer, and the unknown spaceship at the end of the tail was still getting closer.

"I don't know what it is?"

Not only is Yang Meng curious,

Even Xiaoguang on the side also showed excitement when he heard that he might have to catch up with another human astronaut.

……

21 hours after receiving the signal of the anomaly on Ross 128b,

The existence at the end of the trail finally entered Yang Meng's detectable range:

Looking at the gray spots of the mold lake sent back by the deep space exploration device and the radio observation device,

Yang Meng's expression changed a little strangely:

"Statistically, it doesn't look like a spaceship!"

"Xiao Yin! Does the regular shape produce any results? ”

"According to preliminary analysis, it is an ellipsoid with extremely low emissivity!"

"Ellipsoid, isn't it a spaceship?"

"It is impossible to make an accurate judgment at this time, and we need to close the distance to be further determined!"

Hearing such a reply, Yang Meng nodded, and did not appear too anxious,

Human observation technology is still very limited.

Especially in this outer cosmic space that leaves the stellar region,

Because there is no reference,

Even the object in front of the trail cannot be measured in size.

"I hope she's where she is, I'm returning to Planet B!"

Thinking of this, Yang Meng sighed secretly, he was looking forward to it in his heart,

But all the things that happen in this galaxy,

made him have the illusion that he was in a fog,

If that pioneer astronaut is really here,

Why didn't you reply to his arrival?

Why do you deliberately leave this trail at such a time?

And what drove the pioneer astronaut to do these deceptive acts?

"If the end of the trail is not a spaceship,

Then she is likely to lure me away, this Ross 128 system, why would she do this? ”

Until now, there are many things that Yang Meng can't understand.

……

As a human being, Yang Meng still maintains a normal biological clock,

After a single sleep, the spacecraft sailed around the Ross 128 system for almost seven hours.

In this new "day",

Yang Meng, who had just woken up, was about to check Xiao Yin's latest detection data.

At this time, Xiaoguang saw Yang Meng wake up, but immediately came up and said with a flash:

"How is it that the ship your people are flying on is so different from the ship you're on?"

Hearing Xiaoguang's words, Yang Meng, who had just woken up, had a bad premonition in his heart,

He immediately asked Xiaoguang to transmit the latest detection data.

And when he saw the latest clear image, he was stunned,

"What is this?"

see what the image shows,

Yang Meng found that Xiaoguang's words just now were very conservative,

The thing at the end of the trail is not to say that it does not bear the slightest resemblance to the spaceship,

It's just a big rock,

This stone is not a cratered meteorite.

It's like the pebbles he saw on the banks of the earth's rivers,

Looking at such a picture, Yang Meng held back a sentence after a long time:

"Xiaoguang, it can't be said that it's completely different,

Look at the thrusters on the back of this are similar to those on my ship! ”

"It's really similar in terms of particle surges"

"But......" said the little light for a moment,

"Could it be that your people are piloting such a spaceship?

It's too different from the ship you're piloting! ”

"It's a little big!"

At this time, Yang Meng looked at the "pebbles" in this image and continued to confirm some situations to Xiao Yin:

"Is there a signal coming from above?"

"Not detected yet!"

"If there is no signal coming out, then it means that this thing is likely to be in automatic cruise mode.

There's no outside force controlling this thing remotely! ”

"And the specs of this thing look similar to the ships piloted by pioneer astronauts......"

In the absence of a reference before, Yang Meng could not judge its size,

But there is a propulsion device on it, and he can easily deduce something without Xiao Yin's calculations.

"But if we follow the previous speculation,

It's probably trying to distract me, so why was it so easy to catch up! ”

Yang Meng was very puzzled,

"Could it be that as Xiao Yin said, this is a uniquely shaped spaceship?"

"Can Xiao Yin analyze the material composition on its surface?"

"Under analysis......

After spectral analysis, the main elements on its surface are silicon element, oxygen element, sodium element and carbon element......

According to the element proportional analysis,

Its surface material composition is most likely silica and silicate.

"Huh! What a stone! ”

"Can you detect its internal structure?"

"According to the loss propulsion ratio of the thruster, it can be roughly deduced that the interior of the unknown object has a certain solid structure,

If you want to accurately determine the internal structure, you need a certain amount of oscillation data! ”

"Shock data?"

The so-called oscillation data is to approach the big rock in front of you.

And then knock on it a few times,

Although the universe is a vacuum environment, it is impossible to transmit sound,

But solid matter is better than air, the medium of sound vibration conduction,

It's like knocking on a watermelon,

If it is "dull" it represents a state, if it is "empty sound" it is another structure,

Of course, in the face of solid matter with different structures,

The oscillation parameters are also extremely complex, and only an artificial intelligence like Xiao Yin can analyze them in a short period of time.

"Whether it's a spaceship or not, in the state of no reply, you always have to knock on it!"

Yang Meng, who had already made a decision, began to prepare the oscillation detector,

When mining that giant piece of metal on the Rutan system,

He used a shock detector to detect the piece of metal.

So the preparation was very smooth.

And in the process of Yang Meng's preparation, the spaceship also approached the cobblestone object little by little.

In the process of approaching,

Yang Meng asked Xiao Yin to send a communication request to this unknown object with thrusters every fifteen minutes.

to confirm if this thing is a ship.

It's a pity that in this kind of communication cycle,

This pebble still doesn't have any response,

Looking more and more clear, more and more like an unknown object of stone,

Yang Meng also suddenly found that his behavior of wanting a "stone" to respond was a little weird.

"Attention, the concussion detection fuel is filled and ready to be launched!"

Hearing Xiao Yin's reminder, Yang Meng asked:

"How much time is left to catch up with this stone?"

"It's going to take about seventy minutes!"

"Still no answer?"

"Yes!"

With such a reply, Yang Meng was still a little uneasy, after all, the movement of the oscillation detector was very large.

If this "stone" is really some kind of special structure of spaceship,

Under the knock of the high-frequency impact of the oscillator, it may cause unnecessary trouble.

Let's put myself in my shoes.

If something exists on his capsule, some kind of device is installed,

And then the knocking and knocking, he will also feel unhappy.

To be on the safe side, Yang Meng found Xiaoguang again and asked him to help determine something:

"That is, you didn't feel the fluctuations of a fusion device!"

"Yes!"

After getting some kind of answer from Xiaoguang, Yang Meng didn't hesitate,

Gave instructions to Xiao Yin to launch a concussion detector,

As the probe got closer and closer to the pebble-shaped thing,

Yang Meng asked Xiao Yin to use a higher frequency of periodic communication to request communication from the stone,

Until the oscillating detector slowly fell on the pebbles that looked very smooth, there was still no response inside.

"One last communication request!"

"Understood!"

The last communication, which has been clearly told of the existence inside:

"If you don't reply, I'm going to knock you!"

However, after Yang Meng waited for a while,

The communication panel is still blank,

Seeing this situation, he didn't hesitate, and directly gave an order:

"Let's get started!"

With his commands,

The oscillation detector is anchored to the pebbles,

And then I saw,

The firing pin on the oscillator first retracted,

And in the silent universe, a small mushroom cloud with a miniature fire appeared above the oscillating detector,

This is the end of the first stroke.
