The sound of slamming the door outside the door gradually faded away, and it seemed that the walking corpse group had temporarily shifted its target, and the three of them were tentatively safe.

After the nerves relaxed, the muscles were sore and empty, Jing Qiongshuang ran so far with the oversized meat bun of Wogua on her back, and deeply understood the experience of so much meat in Wogua that is not in vain. Wogua himself didn't know that he was carried by a woman, and he only looked at his bloody hands and screamed.

No matter how ladylike a female programmer is, she will reveal her identity as soon as she is programmed, instinctively brushing the hair on her forehead up, leaking out a big forehead, the main reason is because the CPU needs good heat dissipation when running at high speed.

Wogua's already small CPU is now suffering from this bad news, I don't know anything else, but I definitely can't be a programmer.

The most significant advantage of improper programmers is that they don't have to be killed to sacrifice to the sky, if they want to sacrifice to the sky, what they take must not be pork belly, but fat, this mouthful is a bit top, drink champagne with gaffin, this day or another person to sacrifice.

Li Luant sat down slowly against the door, Jing Qiongshuang's elbow had a deep scar that could be seen in the bone, which was probably left by some sharp weapon when she jumped out of the car, but she didn't say a word until now, and this appearance was like black glasses.

Nest melon is by far the easiest, sure enough, it is still the easiest ostrich to mix in the animal world, when something big happens, all you need is a bird's head and a pot of sand.

But there is an age-old problem that can be solved on this topic: why do Africans run so fast? Because the CPU dissipates heat, it needs to be vented through the vents, and more importantly, if you don't change your feet, the soles of your feet will be scalded by sand.

Flipping through the backpack and finding that the number of bullets was still so much, Wogua regretted a little at this time: I had known that I would have let the group of turtle grandsons run away by themselves, what kind of monsters would they fight. He was distressed by the box of bullets that had not had time to be strategically transferred.

The scene was a little quiet for a while, Li Luant took a sip of water, and found that the two of them were very embarrassed, and they were not much better now. At this time, a question came to everyone's mind: why did the man change the direction of the orbit when he was obviously manipulating the walking corpse? Just to kill the target directly? Or do you think that just the walking corpses can't kill them, and it is still possible for your own group to escape?

The lights in the infirmary are relatively dim, and several people have been tossing around outside for so long, this is the most ideal safe haven, and the group of walking corpses is obviously being manipulated by someone to attack, since the person hiding in the shadows has just used the walking corpses to search here, then for the time being, this infirmary will not become the next target so quickly.

It also means that it is time to take a break.

No one took the initiative to mention the shift, because without exception, the current situation is that they are all tired, but Wogua is an exception, just now he slept for more than an hour, and he was carried on his back for so long, not to mention the life of the dragon and tiger, at least there is no sleepiness, but seeing Wogua looking around with wide eyes, he has to hit the muzzle of the gun.

"Since you're not sleepy, you watch, I need to rest."

Jing Qiongshuang dropped a sentence, picked a hospital bed and pillowed his backpack and slept first, Li Luant glanced at the nest melon and patted him on the shoulder, "I'll leave it to you." ”

"I-"

However, the speed of falling asleep is always so fast, it is not allowed to distinguish between the nests, the two have already fallen asleep, and the nests touched their stomachs hatefully, took out a bag of compressed biscuits and began to eat.

"Tick-tick-tick-"

There is no time here, but time has a special meaning here.

I don't know how long it took, Li Luant was woken up by the sound of rats digging holes, but he also stretched his waist contentedly: this sleep is indeed comfortable, since going to the ground, it has not been so comfortable for a long time.

Jing Qiongshuang's nerves have always been on high alert, and after a short period of sleepiness, her spirit recovered, and she pinched her arms that were a little sore, and she saw that Wogua was pouting her ass and digging holes in the wall, not knowing what she was doing.

"Wogua? How long has it been? ”

"How do I know?" I only know that Ben Liangzai's stomach has been called seven or eight times during this period, and Ben Liangzai has been enduring not eating, and then he heard movement in the wall. ”

It's been hours.

The two of them took a look at the left and right of the wogua, but saw that the originally smooth wall was really dug out of a big hole by the wogua, and they didn't know what the wogua was used for, and it was quite round. What made Li Luant feel strange was that he originally thought that this would be an underground fortress rebuilt by the J army during the WWWII period based on a Loulan ruins, but he didn't expect to dig out the wall, and there were no tomb bricks in it at all, only ordinary mortar.

Strange, how is it different from what you think?

After pulling for a long time, he finally took out a guy from the crack in the wall and blew the floating soil on it, "Okay, that's it, it's noisy, it's done now!" ”

The so-called "thing" is nothing else, it's a radio station.

Electricity-Taiwan??

Why hide in a crack in the wall?

There are many different types of radio stations in countries M, E, SL, C, J, D, and Italy in WWWII, such as individual soldiers and vehicles, short-wave and long-wave. The most famous ones are the "BC1000 Radio" of the M Army and the "Type 94 Radio 6" of the J Army in WWWII.

Communication tools are indispensable in both wartime and peacetime, and not all units of Army J were equipped with radios at the time of the WWWII.

In 1936, Radio Station No. 94 No. 6 was developed by the J Army for the infantry of the signal corps, so that 1 or 2 people could operate the wireless KHz while moving - this kind of radio station sends a telegram as a short wave, and after being sent from the transmitting antenna of the radio, it can be received with a frequency of the same band, and the short wave cannot be compared with the medium wave from a technical point of view. In addition, the propagation of short waves is not as stable as that of medium waves due to ionospheric changes, but the technology at that time was limited, and it was already very good to be able to send and intercept telegrams.

Jing Qiongshuang and Li Luant looked at each other, I don't know what they mean, there is a note wrapped in oilcloth on the radio, and the cover is also written in Japanese, just when Li Luant wanted to look at it first, Wogua Mao preemptively started, but after so many years, the note has been gnawed clean by insects, and the rude pinch of Wogua is a mess of ashes.

"This- hehe- you saw it too- this thing doesn't make it sturdy-"

Wogua smiled, knowing that he had done something bad with good intentions, he shrunk his neck and stopped talking.

Although the reason for the corpse was not found before, but deep down in his heart, Wogua felt that if he hadn't chirped at the big-headed ghost, he wouldn't have woken up the sleeping big Lori, and now he just wanted to pull out the intestines of the so-called, waiting for the prince to kiss and wake up, tie a bow and then go on a tour around its duodenum, in order to comfort his IQ and lost sad youth at that time, it was because of that big-headed ghost that he now had his prestige in the team, Directly fell from the moon into the five-meter-high dung pit that he blasted out when he was a child, and the water disappeared with the rolling Yangtze River.

The only evidence that could point out the purpose of the existence of this radio station was pinched into ashes by the nest melon, Li Luant rubbed the ashes, and began to look for a breakthrough from the radio station itself with a little helplessness.

The radio is small in size, and looks like a small suitcase, with a power supply on the left side of the box, and no more common vibrator power supply. The electric button appears just below the power switch. The rest of the electrical key is located underneath the front panel and consists of a simple two-tube receiver and single-tube transmitter housed in a separate box, using the battery as the main power source and feeding a vibrator as the power source to generate the necessary high voltage. The receiver consists of a regenerative geophone and a single-stage audio amplifier. The transmitter is a high-power crystal-controlled oscillator connected directly to a simple coil.

Wogua saw that Li Green Ant had been studying for a long time without saying a word, and he poked and poked from east to west, and he couldn't hold back a little, "Do you see what's wrong?" ”

Li Luant pondered for a while, "I don't see much." The meaning of this is obviously to see what is happening.

"What is this light bulb for?" Wogua touched the bulb of the indicator light with his fat hand.

"The function of the hard disk indicator light on the computer is the same, when the button switch is pressed and released instantaneously, the current of the battery lights on or off the small bulb through the loop, and at the same time generates a current pulse signal, and the bulb also has the effect of limiting current and venting resistance."

Jing Qiongshuang looked at Li Luant: she could only see that the production date of this radio station should be built during the WWWII period, but because she didn't have the tools at hand, she couldn't tell which country produced it, but Li Luant seemed to have found more than herself.

"How much is it not much?" "He has a kind of blind trust in Li Luant.

Other sisters understand everything, you say she is simple, I don't understand anything, you say I am from the village.

As if sorting out the words, Li Luant muttered for a while, "The small number of transmitter tubes and the low power output make it low in power consumption, which is an important indicator of a secret radio station." It shows that this radio station exists separately from this underground fortress, at least it is definitely not operating with all the radio stations in this fortress. ”

"For reliability reasons, batteries are generally used as the main power source for radio stations. Power grid power is not always available and can disappear at any time. In many cases, agents had to operate in rural areas, where the power grid was non-existent. So even though the radio had tried to save money on electricity, it still had to carry at least one or even two car batteries with it. In addition, batteries are charged more frequently, which poses a considerable risk of military operations. However, the use of batteries also provides a defense against the use of ordinary reconnaissance techniques by the military. Orienteering teams would often cut off power to an area while listening to what they thought might be a secret transmitter. If the transmission stop coincided with the power cut-off, they could limit their search to a specific area of the city, but the radio had escaped so many searches intact, and this person was definitely not low in the position of the underground fortress itself. ”

Li Luant paused for a moment, but Jing Qiongshuang had already keenly derived the subtext that Li Luant wanted to express from this passage: the people who own this radio station may not agree with the positions and opinions of everyone in this underground fortress, otherwise why rack their brains to make this radio station not only independent and a secret radio station, but also hidden in the cracks of the wall? What's more, the signal of the radio is very easy to detect, so if this radio station evades the detection of the J army again and again, this in itself shows an important problem-

Those who own radio stations have no low official positions.

After Jing Qiongshuang understood the subtext of Li Luant, her pupils suddenly shrank, and she stared at Wogua for no other reason, because she now knew what was written in the notebook that was pinched into a mess of dust by Wogua just now.

Li Luant didn't seem surprised at all, and seemed to have thought of this from the beginning.

Seeing that the two of them looked at themselves differently, Wogua suddenly tightened his neck, "What are you doing?" What are you doing? This pretty boy sells himself and doesn't sell his art, but he can't be killed. ”

The pretty boy is long, the pretty boy is short, and the pretty boy is hard and doesn't care.

Pretty boy buys me foundation, and I let pretty boy top it to the end.

The difference between the radio station that sends a telegram at the WWWII and the radio station that broadcasts now is that the radio station needs to broadcast the sound, so it must have a microphone and a modulator to modulate the sound signal into a radio signal, and the radio station only needs to send a signal, and does not need to receive a signal.

The transmitter sends a simple mechanically generated dot and scratch signal, which does not require microphones and other equipment, and the transmitter is two-way, both sending and receiving. And the transmitter can also have auxiliary equipment to hit the dot signal on the paper tape, which the radio station does not have.

And there are some other types of radio stations in it. Radio stations at that time relied mainly on radio waves to transmit signals, which were characterized by an almost complete lack of directionality and a slower propagation speed. At that time, because the radio station was not directional, it was basically similar to today's city radio station, and its transmission and reception method was not point-to-point, but face-to-face. The obvious problem with this approach is that anyone can pick up on your signals. Even if you tune your own radio station to a similar band to the other station's band, you can receive the signal from them. But whether you can decipher it or not is not certain, because most of the time the enemy does not use plaintext for communication, the so-called plaintext, that is, according to the standard Morse code. It has been encrypted by a cipher machine, which involves the most important encryption part.

That's right, it was crushed by a slap of Wogua, not anything else, it is the decoder corresponding to the radio, whether it is to receive a signal or send a signal, you need a decoder, and now people put the most important things together with the radio station and handed it over to you, and it was actually crushed by a slap of Wogua??

Jing Qiongshuang now wants to crush the brains of Wogua together to comfort her anger. But after seeing the appearance of Wogua in a mess, he took his eyes off Wogua: Forget it, there is nothing to say about this living treasure.

When the telegraph operator received the telegram, he received not a string of words, but a string of symbols of different sorties, which was Morse code. The function of the codebook is to allow the telegrapher to compare the string of symbols with the codebook to derive the text. The function of the cipher machine is to shuffle the letters represented by each symbol on the codebook, which is the telegram encryption of the WWWII period, which is called the double replacement cipher, and other encryption methods are also mixed with code words, such as boxes (referring to the wounded or materials) and so on. Although the interceptor can decipher it by blind guessing, this method is very labor-intensive, and the enemy often changes the codebook regularly to prevent the leakage of information. The method of repeated blind guessing is undoubtedly very energy-consuming, and for the cipher machine that adopts the double-entry replacement password encryption method, this simple and crude blind guessing decipherment is basically impossible.

However, if you know the working principle of the opponent's cipher machine, you can know how the opponent will scramble the symbols, so that you can easily compare and obtain the information transmitted by the enemy. One of the most typical examples of WWWII is the Enigma machine.

The Enigma machine uses the so-called double-entry replacement cipher, which mainly relies on its internal rotor to scramble and encrypt it. Both the sender and receiver must each have a cipher machine and follow the same procedure so that they can communicate. Each unit of Army D has different settings for the Enigma machine, and it is almost impossible for the interceptor to decipher it, because there are almost tens of millions of possibilities.

Therefore, the Allies attached great importance to the research project of the Enigma machine in WWWII. Because as long as the Enigma machine is studied thoroughly, the Allies can also obtain the information of the D Army just like the receiver of the D Army. The Allies initially obtained the actual copy of the D-Army Enigma cipher machine in 1941, which was found by the Navy of Country E on the captured D-Force submarine U110. The Allies then organized personnel to decipher and analyze it, and finally completed the entire work around 1943. Coupled with the transmission part mentioned above, combined with the knowledge of the password encryption method of the D Army, the Allies have been able to obtain a steady stream of D Army intelligence since 1943. This is how to intercept telegrams.

During the war, when the Yamato went to Okinawa to carry out the so-called jade crushing special offensive operation, there was an M army submarine that discovered the traces of the Yamato, probably overconfident, the M army submarine did not encrypt the telegram, and directly sent the Yamato movement to the headquarters in plaintext, this telegram was not far from the Yamato when it was sent, and it was also intercepted by the Yamato and learned, and then the Yamato thought that the hidden track was useless, so it went straight to Okinawa to die, which is also one of the few examples of plaintext telegrams in the war.

It's like a question women often ask men: How would you feel if you lost me one day?

A: It's like a stir-fry without salt.

Q: What a literary style, do you mean that life is boring without me?

A: No, I mean go buy another pack.

Now the question is: what if Wogua crushes the decoder that comes with the radio station?

Answer: Lift off his Celestial Spirit cover.
