Before going to sleep,

Yang Meng finally checked the various equipment on the spacecraft,

Determined the next course again, and checked Xiao Yin's own state,

Although the loopholes on Xiao Yin's body have not been completely repaired, it is impossible to repair them with his ability.

But in the face of such a security vulnerability, Xiao Yin,

Yang Meng doesn't have the idea of moving the place for Xiao Yin yet,

It's still a long way from the solar system,

Only when he is close to the range of a few light years from the earth, he still has many places to rely on Xiao Yin when he needs to sleep.

After checking the equipment, Yang Meng returned to the sleeping cabin,

Check your physical condition and see that your body functions are completely dormant.

He didn't hesitate much, and went directly into the sleeping cabin,

However, when entering the hibernation pod, he remembered one thing:

"According to the time, the new cycle of communication should have arrived, but there has been no news from the Earth side until now!"

"That's it!"

Yang Meng expelled the distracting thoughts in his heart, stopped thinking nonsense, and obediently lay down in the sleeping cabin.

With the merging of the hatches of the hibernation pod,

The entire hibernation pod was completely plunged into darkness.

A dark and claustrophobic environment always causes discomfort to humans.

Fortunately, this discomfort disappeared with the addition of hypnotic gas and cryoprotective liquid.

Yang Meng's consciousness gradually disappeared.

In a sense,

When the temperature in the sleep chamber rapidly decreases to a temperature close to absolute zero,

The time in his brain is also stuck in this moment,

Because the particles move very slowly,

The consciousness in his brain is barely active,

This lieutenant will be a dreamless dormant.

……

Time is an imperceptible existence for Yang Meng in a state of cryodormancy.

But not feeling it doesn't mean that time isn't flowing.

Before human beings constructed an environment of absolute zero,

It is impossible to keep a dormant person immortal.

In this state, the particles are still inevitably moving slowly in this sleep chamber.

At this point, the various particles struggle to move,

But it's as if you're bound by an invisible force,

And in the next moment of human consciousness, the restraints on these particles suddenly disappear,

The temperature in the hibernation chamber began to rise rapidly.

At this time, the temperature of the hibernation chamber is rapidly rising, and it will soon reach the temperature of normal human body temperature.

At the same time, cryoprotective fluid was pumped out of the various pipeline sleep chambers, and the cabin soon became clean.

At this time, Yang Meng's consciousness slowly recovered,

His memory stays before he sleeps,

But the familiar feeling in his body made it clear to him that he had been dormant for a long period of hypothermia.

"I don't know how long this hibernation has been?"

This is the first thing Yang Meng thought about when he regained consciousness.

"There is no emergency sound, and it seems that this time it is likely that there was a normal hibernation!"

This is the second thing that Yang Meng thought of after regaining consciousness,

As the temperature returns to normal,

Yang Meng's thinking is also active,

After these two thoughts flashed through his mind, he looked at the time on the side of the sleeping pod,

The time shown above was exactly as he had expected,

Twenty years have passed since he left the planet Ross 128b,

Time had passed so long in reality, but everything in his memory still seemed to have happened in Fangcai.

"I didn't expect this hibernation to go so smoothly!"

After calming down for a while, Yang Meng finally floated away from the sleeping cabin and began to check the status of the spaceship.

In these twenty years,

The spacecraft traveled 4.1 light-years in space at 18% to 23% of the speed of light.

If he is still 6.8 light-years away from the solar system,

According to the plan, two or three more hibernations will be carried out to get close to the solar system.

But considering the state of the solar system today,

The closer Yang Meng gets to the solar system, the more cautious he needs to be.

If you go dormant for that long, you won't be able to react to some dangerous situations.

"That's it! It's still some distance from the solar system,

Let's take a look at the situation in the past 20 years!"

Thinking of this, Yang Meng cleaned up his mood and came to the equipment cabin,

In the equipment cabin, Xiaoguang is still in a dormant state.

Yang Meng didn't bother Xiaoguang's thoughts,

He first opened the three-dimensional star map and determined the current equipment of the spaceship.

From his position,

His nearest star system is Barnard's star, which is 6.3 light-years away.

In addition to this star system,

The second closest is the solar system.

As for the closest Proxima Centauri galaxy to the solar system, because above the other side of the solar system,

At this time, the distance from him is more than 10.8 light years,

It can be said that the position of the Boundless Oriental at this time,

It's a very empty universe with few nearby stars.

And in this case,

It is also the result of Yang Meng's deliberate choice,

Considering the situation of the gray forces, the spacecraft tries not to pass through the stellar region on the way back,

Even to avoid entering the range of a star three light years,

In this way, you can avoid encountering gray forces to the greatest extent, and being discovered by some radical human forces.

With his knowledge of human observation techniques,

Whether it's a force on Earth or a gray force,

It is not easy to observe and track a spacecraft less than a kilometer away from three light years.

As long as he doesn't send any information from the spaceship,

At a distance of more than three light-years, the spacecraft is essentially equivalent to stealth.

Unless he is extremely unlucky enough to encounter a wandering probe released by humans,

He can be discovered, and the probability is very pitiful,

After all, the vastness and emptiness of the universe is far beyond human imagination

Like the moon that humans see on Earth,

In this distance between the earth and the moon, the remaining seven planets in the solar system are also more than poked.

It is this emptiness that

Yang Meng thought that it would be very easy to find a path to avoid other stars.

The solar system is sparse around it,

It is this sparseness that has created the stable development of today's civilization by human beings.

Instead of a sudden catastrophe because of a catastrophe in the galaxy,

If the solar system is not at the edge of the spiral arm of the Milky Way constellation Orion,

It's in a star-dense region in the spiral arm,

Then, every tens of thousands of years, there will be a supernova explosion, or a Gamma ray burst of neutron stars and black holes.

And in this sparse case,

He only needs to avoid two star systems, a total of four stars,

Because there are only two star systems within six light-years of the solar system,

First Proxima Centauri, located 4.3 light-years from the Solar System,

This galaxy is made up of three stars, and these three stars can be seen as a star system.

At this time, Proxima Centauri is on the other side of the solar system and does not need his attention.

And what really asked him to pay attention was that Barnard, which is 5.8 light-years away from the solar system,

Although his current position is used as a reference point, Barnard is on the side of the solar system, more than 6 light-years away from him,

But long before he left Rutan, humanity had already established an outpost on Barnard.

And it took him almost 50 years to get from Rutan to the Ross 128 system,

And from the planet Ross 128b to hibernate here for 20 years,

In the course of more than seventy years

He didn't know to what extent the human base there had been built.

Has a cosmic deep space observatory been established?

Is it possible to track and observe spacecraft?

With his knowledge of the second-closest star system to the solar system,

The human base there should have developed to a certain extent,

In his mind, Barnard was a red dwarf like Ross 128 and an ancient star.

This means that the planetary system of this galaxy is extremely stable.

As a result, humanity has abandoned Proxima Centauri, which has an extremely harsh environment.

The first site that left the solar system was established in Barnard's system.

Thinking back to some of the circumstances of the Barnard galaxy,

Yang Meng looked at the heading map again,

Over the next few days, the ship will get closer and closer to Barnard.

However, because Barnard is on the side of the solar system,

He is only 5.1 light-years away from Barnard.

And then it's away from the galaxy again.

Slowly reaching a distance of 5.8 light-years, by which time he was back in the solar system.

"If, the extremist forces of humanity or the gray forces, through the deep space observation base in the Barnard system, perceive my existence,

then they should have sent some probes,

Even manned aircraft coming towards my course,

Maybe those things are already on their way!"

"But I'm so far away from that galaxy right now, do they really notice it?"

Yang Meng felt that he was a little worried,

But after thinking about it carefully, I decided to take advantage of this wake-up gap to make some preparations.

……

Three days later,

Yang Meng arranged some defensive means on the spaceship, and as for whether these defensive detection methods were useless, he had no bottom in his heart.

After all, there is a generational gap between him and the earth in terms of scientific and technological level.

And after solving this matter,

Yang Mengcai decided to move on to the next matter,

At this time he floated in front of the porthole,

Looking at the scene outside the porthole, because there is no interference from any stars, the scene of the Milky Way is also extraordinarily beautiful,

Even if he had seen it countless times, he couldn't get tired of seeing such a scene.

However, at this time, Yang Meng didn't have much heart to appreciate such a scene,

I don't know how long he has been floating in front of the porthole, but he still sighs after all,

Pushed the porthole, and with the help of the reaction force, floated to the cabin behind him,

And above the hatch of this cabin, there is a metal nameplate engraved with the words "communication cabin".

If you change it before,

Yang Meng woke up from hibernation, and after determining the condition of the spaceship, the first thing he did was to float into the hibernation capsule.

Unpack the geocyclical communication packets that have been accumulated during the dormant period.

It can be said that when he read the letter from the earth, he was the happiest moment in the lonely voyage.

The information from Earth was the most precious thing to him when he was far away from his home planet.

But now,

It's been three days since he woke up from his hibernation

Time

But he never came to the communication cabin to unpack the periodic communication.

He's running away from something,

But after all, he is a professional pioneer astronaut, and he still has the courage to face this.

"There's no point in running away!"

At this time, Yang Meng came to the sleeping cabin and began to check the communication packets.

"One, Two, Three......

Yang Meng counted it and found that there were a total of eighteen cycle communication packets.

And he silently calculated, he himself did twenty years of dormancy, plus the packet that should have been received in the Ross 128 system,

There should be 21 packets here.

"Three packets missing!"

In the face of this abnormal situation, Yang Meng's face did not show any emotion, as if this situation was very normal.

And the reason for this situation,

He also knew very well that it was because he had to change the way he received information.

In order to avoid being found yourself,

He left some relay satellites in the Ross 128 system,

Through these relay satellites, periodic communications from the Earth are transmitted,

In order to further avoid the data packets emitted by the relay satellite from being shot into the solar system,

In the process of transmitting the packet,

The relay satellite uses a very narrow cluster signal, and during the spacecraft entering the solar system at a curved angle,

Information is emitted to the vertices of the curve that the spacecraft may pass.

So that the information sent by the relay satellite does not enter the solar system.

Nor will he be exposed by passively receiving the Earth's periodic communications.

It's just that using this method to collect information about the earth will have many drawbacks.

The first is the signal delay caused by distance.

Signal relay in the Ross 128 galaxy will inevitably lead to a significant extension of the information distance.

Originally, it took ten years for the packet to travel from the Earth to the Ross 128 galaxy.

Now it takes another four years for the information to be sent to him.

And it is precisely because of this additional four-year journey,

There were three packets that did not reach the Boundless East.

Thinking of the troublesome things in the process of receiving data, Yang Meng shook his head gently,

"I haven't sent periodic communications to Earth since twenty years ago

The earth side should have begun ten years ago to begin unable to receive communications from my cycle,

After ten years of not replying,

The Earth side should have noticed the anomaly,

Maybe right now in the universe, there's already a packet thinking about the Ross 128 galaxy!

If we can intercept this packet, maybe we will be able to understand the attitude of the ball."

Yang Meng is very clear about the data path of the Earth sending information to the Ross 128 galaxy.

That path is fixed,

He only needs to launch a probe near that road, and he can intercept the information.

But it is precisely because of the fixation of the path,

Not only is he aware of this path, but as long as human beings with astronomical observation technology are aware of the existence of this path,

In addition, Cai Zhaoxin is the only one of the sixteen pioneer astronauts of mankind who is missing,

There are many humans watching this communication path,

If he approached rashly, it was almost equivalent to exposure.

So, after much consideration, he didn't send any devices to that route out of the pioneer astronaut safety first code.

"That's it! I don't want to think so much!"

"Let's take a look at what the Earth side says in a dozen packets! You might be able to find some useful information......
