Shi Hong still wanted to replenish supplies on this green planet, but Zhen Fei vetoed it with a word: "Our supplies will not be a problem for a hundred years, so forget it."

After continuing the voyage for half a year, he has been traveling in the vast darkness.

Suddenly, the observer saw a curved pattern of seven stars, much like the Big Dipper, and showed the photo to Zhen Fei to see.

At first glance, Zhen Fei said, "Where is this Big Dipper?" This is a hook style, and the Big Dipper is a rice spoon style. ”

The observer said: "King Ying, it is impossible for us to stand on the earth and observe in the starry sky, which is what it looks like, have you forgotten the truth that the side of the ridge is a peak?" ”

This sentence reminded Zhen Fei, and he said, "Then, let's take a look in another direction." ”

"If we change directions, first, we need to deviate from the course, and second, we need at least a month's sailing time, can we afford to delay?" This is a big problem. Zhen Fei also hesitated.

Then he called Qiao Bushi over and saw if he could measure it into the shape of a rice spoon according to the positions of the seven stars in the starry sky.

Qiao Bushi observed for an hour, and after three hours of tapping on the computer, he said: "I can't tell if it's the Big Dipper, but we need to sail in another direction for twenty-one days to see these seven stars become different." ”

This time, Zhen Fei said ruthlessly: "Then let's find another angle, after all, the hook is not much different from the rice spoon, I think it should be the Big Dipper." ”

The night sky seen on Earth is not exactly the same as what you see in the starry sky, only the distance is too far away, such as Cygnus, which is a full 10,000 light-years away from the Earth, and this distance is still estimated, because no one can observe it under an astronomical telescope for 10,000 years.

If a person turns on a flashlight at a distance of one light year, it takes a year for the light of this flashlight to be transmitted to the earth, and then the person turns off the flashlight, and the person on the earth sees that the light is gone, and it is already a year later.

This is the phenomenon of distance, which seems to be very abnormal, but it is real.

Zhen Fei and others have been sailing in the starry sky for three years, and the distance to go out is still very close. That is, the earth is four times as far as the sun. The range did not leave the solar system. It would take three million years to get to the banking system.

Human beings seem to be very powerful, but in the face of the vast universe, they are still as small as ants.

There is a star in the distance, Zhen Fei can't tell if it's the sun, all the stars are the same, they are all burning fireballs, in fact, the inside is undergoing nuclear fission, the surface temperature has reached tens of thousands of degrees, and the core temperature is around hundreds of thousands of degrees.

In the end, it was Qiao Bushi's brain that was agile and said: "Don't you often say that earthlings use radio waves to communicate? Let's use the radio waves to get in touch and try it, after all, the speed of light is much faster than that of a battleship. ”

This is a brilliant idea, Zhen Fei remembered the military band used when he was in the underworld, at that time they used short wave, the distance of transmission is very close, because there is no satellite in the sky to broadcast, the distance between each other will not exceed 1,000 kilometers, basically about 500 kilometers, and a little further need to set up an iron tower on the high mountain to broadcast the signal.

But Zhen Fei still remembers the frequency of their contact with each other.

The so-called relationship between frequency and wavelength is like the frequency of the Santana car, and the wavelength is the amount of refueling. It was also a car of the same model, the one with more fuel drove from Shanghai to the capital, and the one with less fuel drove to Zhangjiagang.

If Zhen Fei wants to get in touch with his family, he has to use a Santana car, but he has enough fuel now, and he can send the signal to the family, if the family wants to continue to contact him, they must use the Santana car that is also fuel-sufficient, and then they can go hand in hand.

So Zhen Fei ordered the radio personnel to change the frequency and use the clear code to transmit the signal. The so-called clear code means not encrypted, now the military system on the earth is the most secret unit, the military organ telegraph uses a special encryption method, must use a fixed computer to decrypt, that way is very complicated, Zhen Fei did not learn, but the technology of clear code telegram is very simple, a little learning can be used.

These transmitters with the same frequency repeat the same sentence: "Tang Xiaoxiao's beloved wife, please answer when you receive it." ”

This method of communication was originally with the attitude of giving it a try, but an hour later, I suddenly received a reply: "Husband, is that you?" ”

After replying to the letter, Zhen Fei was overjoyed and hurriedly called back: "Yes, is Qiao Huizi's beloved wife also there?" "It's a way to confirm. Zhen Fei needs to confirm whether it is really Tang Xiaoxiao.

This time, it only took two minutes for the other party to return the message: "Yes." And Qiao Keiko is also there. ”

This proves that Zhen Fei has made contact with Tang Xiaoxiao.

Then Zhen Fei replied in the manner of Professor Qiao Bushi: "You keep answering, 1, 2, 3...... These numbers, I'm going to look for the way home and the distance. ”

"Okay, we're excited to hear from you, don't worry, we're all right."

"Everything about me is fine, too." Zhen Fei replied.

Then, according to the signal sent by the other party over and over again, Qiao Bushi first used radar to determine the direction of the signal, and then determined the distance according to the interval between the previous number and the next number of the other party, which was basically about fifteen million kilometers.

This distance requires the king ship to fly for about 14 days.

Since contacting Tang Xiaoxiao, Zhen Fei has talked to the other party, and he said, "Do you only have one transmitter there?" ”

"I have more than a hundred units here, and I have been in contact with you for nearly five years, General, I am a samurai under Commander Leng, a person belonging to the Women's Legion, and I have informed Madame that she is rushing over."

"I see." Zhen Fei immediately knew why the other party hadn't replied for a long time when he sent a report for the first time, and he must have been studying and asking for instructions on this very unexpected clear code.

He was very excited, and since it was a clear coded telegram, anyone who had a telegraph could receive this signal, so he didn't say much secrets. Just gave the other party a clear answer: "I will arrive on Earth in half a month." ”

Although Zhen Fei was very careful, this sentence exposed a lot of news.

Leng Xiao used more than 500 female warriors from the Women's Army to send a report to the earth on the small island of George Strait using the same frequency, with only one content: "Husband, where are you?" Leng Xiao misses you. ”

This message is still in clear code, which seems to be relatively low-level, and no one cares about this news. But no matter how ordinary a sentence is, 24 hours a day, the same information is constantly being sent, and often more than ten high-power transmitters are working at the same time, which attracts people's attention.

Anyone understands that this phrase is looking for a signal of the same frequency.

Zhen Fei has been away from the earth for nearly five years, and this signal has been shouted for nearly five years.

There was a man named Anna in California, USA, who was a radio amateur who specialized in radio technology. He had received the signal four years earlier, and at first thought it was someone like him who was debugging the telegraph signal. After all, no one uses the clear code telegram, and the person in contact can make a direct call by dialing a phone number, and the way of sending the telegram is backward, and the cost is very large, and the translation labor, mechanical equipment, etc., far exceeds the price of a telephone.

Arna didn't expect that it would be such a simple signal. After shouting for more than four years, Arna suddenly began to doubt in his heart, and he always believed in one thing: "The greatest equipment is often the simplest, the most ordinary action, often the most secret." ”

Why is that? The simpler the equipment, the less likely it is to be damaged, and the more complex the mechanical problems. And what seems to be the simplest greeting is hidden secrets that outsiders don't know.

A clear code signal can call for several years, day and night, what kind of financial and human resources can support it?

The longer this signal is called, the more amazing the secret it turns out.

Arna made it much simpler, he entered this signal into the computer, and processed it automatically, as long as it was this signal, he didn't pay attention to it at all, and if someone used this frequency to make contact, the computer immediately called the police.

Just after Zhen Fei contacted the warriors on Earth, the situation immediately changed. Arna was shocked, he looked at every word of the contact between the two sides, it seemed to be very ordinary, but Zhen Fei's words "will arrive on Earth in half a month", "under the command of Commander Leng" and "Women's Army" made Arna stunned.

In Arna's mind, the first thought was, "Aliens are coming." But the messages were in Chinese, which was difficult for Arna, who was able to translate them using a translation software.

Then, three names appeared in the message: "Tang Xiaoxiao, Qiao Huizi, Leng Xiao." ”

Arna searched on Google and found that in the far east, Huaxia really has the information of these three women, especially Qiao Huizi and Tang Xiaoxiao, one is a movie star who was once popular, and the other is a pharmaceutical tycoon, rich and rival the country, only this Leng Xiao is more mysterious, and he has been missing for seven years. No one could find any trace of Leng Shino.

Arna couldn't help but associate with the message: "Could this Leng Xiao be sent by aliens to do Infernal Affairs?" Arna did not suspect Qiao Huizi and Tang Xiaoxiao, but suspected that she was not an earthling from Leng Xiao's whereabouts.

But if the message is not faked, it is easy to deduce that Tang Xiaoxiao, Qiao Huizi, and Leng Xiao are all the wives of this "husband".

There is also a technical problem with this, that is, the telegram sent by the samurai of the Women's Legion is around the earth, and this signal can be received from any corner of the earth. But Zhen Fei's radio waves were emitted from the starry sky.

Therefore, Zhen Fei couldn't receive the signals sent by the people of the Women's Legion for more than four years, and the signals sent by Zhen Fei covered the entire starry sky and could easily reach the earth. When the samurai of the Women's Legion received the same frequency of replies, they hesitated. They are proficient in radio wave technology and sense that there is something abnormal in this signal, but the same sentence "Tang Xiaoxiao's beloved wife" has been sent non-stop.

Based on such a dense radio signal, the samurai also determined that the signal did not come from Earth, but somewhere in the starry sky. Then the samurai adjusted the direction of the launch and sent a reply in the direction of the overwhelming "Tang Xiaoxiao's beloved wife" signal. In this way, the radio waves were transmitted to the starry sky and received by Zhen Fei and the others.

This can explain why Zhen Fei has not heard from him for five years.
