After half a night of tossing, the bamboo basket fetches water in vain.
The eight people were listless, but they didn't want to sleep. They didn't even bother to find the black floor. They just sat on the floor at random, drooping their heads, in a daze, or melancholy, as if they didn't care about the cool air under their buttocks.
The atmosphere of the entire back kitchen was dragged into an endless black hole of depression by these eight frosted eggplants.
"It seems that someone upstairs is going to beat us..." Qiao Siqi reminded his friends weakly.
"If you can really jump off, let him beat you. I'd be depressed too." Zhou Lv sighed, and silently wiped the blood on the blade with a dirty rag he found somewhere.
"Actually, there is no signal. I am not afraid. There are problems with the mobile phone and the Internet. It is normal for the TV to have problems. I am afraid..." Luo Geng hesitated to speak, and it took a long time before continuing, "I am afraid that the signal source is damaged and the news cannot be transmitted, but There's no news at all."
"Impossible," Song Fei denied without even thinking about it. If he had hesitated before, he is now firmly convinced, "We fish, shrimp and crabs can kill a few zombies, and the country can't control the situation? It is difficult to settle the 9.6 million square kilometers, but it is absolutely no problem to concentrate our forces to stabilize the heart area first."
"Then I can't figure it out," Qiao Siqi crossed his legs, adjusted his sitting posture, his brows were furrowed, and his tone was quite resentful, "This TV signal is not like a mobile phone signal, and it needs A base station is built nearby, isn’t a TV tower enough, once the signal Biubiubiu is transmitted, the TV receives it, and it’s done. Could it be that the TV tower was also pulled down?”
Song Fei was at a loss for words. I always felt that Qiao Siqi's statement was weird, but as a layman, he couldn't tell how ugly he was. It is obviously the most common thing in life, but it seems that I have never thought of exploring its technical principles.
Subconsciously looking at Qi Yan—it has become Song Fei's deep-rooted cognition to find Qi Yan when he encounters a problem that he can't understand.
Originally, student Qi only wanted to lower his eyes and be a competent crowd listening, but when Song Fei's voice suddenly fell silent in his ears, he knew that what was supposed to come would come.
Lifting the upper eyelids hesitantly, as expected, a pair of eyes yearning for the truth.
In the past, Qi Yan enjoyed being stared at like this, because he was always able to answer questions fluently, even eloquently. The questions Song Fei can ask are nothing more than study, life, life, ideals, youthful years, no one would suddenly ask while talking about love, hey, do you know how TV works
"Cough," Qi Yan cleared his throat, and analyzed half-guessingly, "The signal sent by the TV tower is similar to the wireless signal, the one received by an antenna? But now it's all cable TV, I don't think it should be biubiubiu It's that simple."
Song Fei was thoughtful, and felt that what Qi Yan said seemed reasonable.
Although the answer was directed at Song Fei, it was Qiao Siqi who obviously refuted, and the latter was not happy: "You mean the TV tower is useless now? It's purely for sightseeing?"
Song Fei hadn't figured it all out at first, and being surrounded by Qiao Siqi, he felt that Qiao Siqi's question was right, and then looked at Qi Yan again.
Student Qi couldn't make it up anymore, so he spread his hands helplessly and said frankly: "I'm just a student of biology."
Song Fei was stunned for a moment, and then said blackly: "Then just say you don't know or not!"
Qi Yan hangs his head in despair, speechless.
Today is different. He is still him, but Song Fei is no longer that Song Fei, and the world is no longer that world—I used to pretend to be a force, let's pay it back slowly.
"Who said that the TV Tower is purely for sightseeing," Lin Dilei, who had been listening, finally found a place where she could interject. To be honest, although she studied broadcasting and hosting, she still has a little understanding of the communication engineering field when it comes to the transmission of TV signals, but when it comes to the role of the TV tower, she still knows the general idea, "The reason why the TV tower is repaired so well High, because of the need to receive and transmit signals. In the early days, when there was no cable TV, old TV sets had antennas, just to receive the analog signals emitted by TV towers.”
Qiao Siqi was still puzzled: "You also said that it was the early days, and now every household has cable TV, who still uses antennas, wouldn't the signal be useless?"
Lin Dilei breathed a sigh of relief, and patiently explained: "There are always places without cable TV, such as remote mountainous areas, so at this stage, a certain amount of analog signal transmission must be maintained. Moreover, TV towers do not only transmit TV signals. If you I have looked carefully, and they are generally called radio and television towers. In addition to transmitting TV signals, they also send out radio letters..." Lin Dilei was shocked suddenly, with a surprised expression as if she suddenly realized something terrible.
The comrades who had listened carefully to the lecture with a learning mentality were startled by her expression.
Song Fei quickly asked: "What, what's the matter?"
Lin Dilei came back to her senses, ignoring the explanation, and said in a hurry: "Quick, take out all the phones!"
The comrades-in-arms didn't know why, but seeing that Lin Dilei was in such a hurry, how dare she refuse to follow suit, and immediately took out her pockets and rummaged through them. Within a few seconds, five mobile phones were presented in front of her as if they were tributes, plus the one in her own hand, There are two Apples, one Samsung, one Huawei, one Xiaomi, and one OPPO.
Qi Yan and Qiao Siqi watched quietly, silently offering a bowl of wine to the fruit machines of Lin Dilei and Li Jingyu, two classmates - although they thoughtfully passed their respective chargers to the rear. A generation of fruit party, but based on combat experience, it will be a matter of time for these two machines to die heroically.
Lin Dilei looked at the mobile phone that was piled up in front of her in an instant, and couldn't laugh or cry: "Who told you to give it to me, and I can't unlock the lock screen. I asked you all to take it out and look for it yourself. Is there a built-in radio!"
One word awakens the dreamer.
Song Fei really wanted to beat himself up, why didn't he think of it, he couldn't get TV, he got radio!
I think there should be mobile phones. Song Fei opened the system tools folder—in fact, this folder is equivalent to his utility room, and he would drag all the inbuilt programs of the mobile phone that cannot be removed or used by him to this place—searching for a long time, the tape recorder saw a , but there is no icon for the word radio.
The other friends were similar, first excited, then confused, and finally disappointed.
Only Wang Qingyuan’s Xiaomi has an FM radio station, but upon closer inspection, it’s the kind of Internet radio station that listens to traffic. .
"Impossible." Luo Geng searched for it several times without giving up. He knew intellectually that there was no such thing, but he couldn't accept it emotionally. Generation gap?!"
The friends couldn't explain it, because they were also confused.
Everyone thinks there's a radio in your phone, but really, it's just missing.
Only Qiao Siqi tried to look back on his mobile phone journey, and seemed to find some clues: "Maybe it really has been updated. My first mobile phone was bought by my dad when I was in the fourth grade of primary school. It was flipped back then. Well, I can listen to the radio, and I always listen to it secretly. Later, I changed to a smart phone in the first day of junior high school, and it also has a radio. You need to plug in headphones to listen to it. I remember it very clearly, but I have no memory of the mobile phone I changed after high school. It seems to be there, but I haven’t used it again. At that time, there were too many things that the mobile phone could do, and no one listened to the radio, and then went to college, changed fruits, and didn’t pay attention to various apps on WeChat and Weibo every day.”
Certainly not all mobile phones of all brands and models will be castrated without the module function of the built-in radio, but if the mobile phones of Takeshi Class 1 are used as samples for the sample survey, then this is definitely the trend of the times. However, if Lin Dilei hadn't mentioned it, they wouldn't have thought of such a thing—the times are developing so fast that everyone keeps chasing new things, and they don't even realize what things are changing quietly, even not see.
Just like the TV discussed before, you use it naturally and accept that there are programs when it is turned on, but if you think about it carefully, it has actually changed from an antenna to a cable unconsciously, and from a set-top box to a TV. With a set-top box, it has changed from a stand-alone computer to a networked one, from what it shows you to watch to what you choose to watch, and even started to be able to install APPs.
This change is so huge, and the technological change behind it may be earth-shaking, but when it falls into life, it becomes a breeze. For most users, the alternation of new and old technologies is a silent process of moistening things, just like few people can accurately remember the time when they first used QQ, when they first downloaded WeChat, or when they first The time to install Alipay for the first time. When you come back to your senses, they are commonplace.
Boom.
The familiar sound of radish knocking on the window sounded again.
The friends who have not yet recovered from the blow of Snowflake TV and were hit hard again by the demise of the radio did not react for a while.
Boom boom boom.
The radish was very anxious, and hit it three times in a row.
Song Fei walked to the side of the floor bunk, took out the flashlight from the backpack that was pressed against the corner of the bunk, and then went to the window, opened the blinds and snapped them on—the window was empty, except for a carrot with a note tied on it.
It seems that without the attraction of singing, the zombies should have returned to the hall to avoid the cold.
Turning off the flashlight, Song Fei quickly opened the window and took down the note. After the window was locked, he read it on the spot.
It was still in the beautiful small characters before, and for no reason, Song Fei felt that it was Huang Mo's handwriting.
"What are they going to do? They won't get more and more angry and really want to come down to fight?" Zhou Lv asked a little nervously.
Qiao Siqile: "Didn't you say that if they want to beat you, let them beat you? I guess they heard your sincerity, and they didn't want to come down, but they were so moved that they decided to come down."
Zhou Yili black line, just about to say something, was interrupted by Song Fei who read the note—
"They said they wanted to come down and talk to us about something."
The little friends are surprised, it is already midnight, theoretically speaking, it is not a particularly suitable time to be a guest.
"How should I say it?" Song Fei asked everyone's opinions, "Should they come down?"
Everyone looked at each other, unable to make up their minds for a while.
Cooperation is one thing, and face-to-face is another thing. Although it's a bit petty to think this way, the amount of food reserves upstairs is definitely not comparable to that downstairs. If they do one thing to lure wolves into the house, they can shadow them for a lifetime.
"Are you sure there are only six of them?" Luo Geng looked up at Song Fei and asked.
Song Fei nodded immediately: "Yes."
Lin Dilei also said: "I testify, only six."
"Then let them come down," Luo Geng looked at the friends, with a tone of discussion in his tone, "Eight against six, we may not be at a disadvantage."
Think about it for a moment-
"Row."
You can use plastic bag ropes to tie radishes, but when you really climb down, it’s the same as Song Feilin Dilei’s previous descent, and you can only tie them with clothes. Fortunately, only four students came down from class 2 at the end, so all of them were neatly dressed. The two people stationed upstairs should have had nothing left, so the fourth person had just landed, and the clothes rope was pulled back with a swipe.
Song Fei and the others brought people in as quickly as possible. The four guests were Zhao He, He Zhiwen, Huang Mo and Feng Qibai.
As Qi Yan closed the window and locked it, the number of students in the back kitchen on the first floor increased to twelve.
The four of Zhao He stood by the window, still at the boundary they had stood after jumping in. They hardly moved half a step, and they were visibly tense.
The eight people in Class 1 did not dare to take it lightly.
Twenty-four eyes met, and there was an embarrassing silence for a while.
Song Fei was familiar with both sides, so he could only stand forward when he saw this, and asked Zhao He, who was the leading brother, from three meters away, "Friend or jackal?"
Zhao He was puzzled by the question.
He Zhiwen and Feng Qibai also didn't understand.
Huang Mo smiled, her smile made her only be regarded as delicate and her facial features were inexplicably moving: "A big river has wide waves, and the wind blows rice flowers on both banks."
Song Fei grinned: "When friends come, they have good wine, when jackals come, they get shotguns."
He Zhiwen and Feng Qibai recognized that this was "My Motherland", looked at each other, and suddenly one of them clamped Zhao He's arm.
Zhao, who also understood, gritted his teeth and said with difficulty: "Don't worry, I can bear it."
But why are there such hateful people in the world! ! !
After such a special opening, the atmosphere revived. Although it is still unavoidable to be on guard against each other, this kind of guarding is more like the survival instinct in a virus crisis state, and it is different from maliciousness.
Without malice, you can live in peace.
Of course, whether a deep friendship can be produced will be left to time.
The four of them were invited to sit on the ground floor. After taking a quick look at the environment, Class 2 students understood that this was considered honored guest treatment.
The eight little friends who were sitting around at random also picked up their mobile phones and surrounded them. The bunk on the floor was a bit crowded and warm at the same time. There were 12 people who were next to each other and squeezed each other.
"Why are you all holding your mobile phones?" Feng Qibai looked around strangely, and found that several people were holding their mobile phones, "Isn't the Internet disconnected? It's the middle of the night, playing stand-alone games?"
He does not mean that.
The sad thing was brought up again, and Song Fei sighed: "Don't mention it, I finally had an epiphany, and remembered that there was a broadcast, but no one has a mobile phone."
"We have." Feng Qibai said suddenly.
The eight friends stared wide-eyed together: "Huh?"
"But it's useless." He Zhi asked about the interface, and at the same time took out his Huawei from his pocket, unlocked the screen, clicked twice, turned on the radio, plugged in the earphones, and finally handed the white ear wires to Song Fei.
Song Fei in this room took the earphones and stuffed them into his ears, while Luo Geng in the other room looked at his own Huawei, choking speechlessly—they all fucking support domestic products, how can people choose a model with a radio as soon as they buy it!
Sizzle.
la la.
Zi la la.
After struggling for two minutes, Song Fei finally confirmed that there was no human language in the headset. Even Spanish Arabic is fine!
But he didn't give up: "It's all electric sounds, why don't you try another channel?"
He Zhiwen raised his mobile phone, showed him the screen, and said helplessly, "I've been tuning the station. Didn't the campus radio ring when the accident happened? At that time, I thought of using the mobile phone radio, but it didn't work. The built-in radios of mobile phones are basically FM frequency modulation, which belongs to the ultra-short band, spreads in a straight line, and the transmission distance is very limited, and this band can only listen to local programs.”
"That's not right," Luo Geng recalled the years when he was tortured by his father's radio again, "My dad listened to what time was FM all day long, and sometimes he put earphones on me to force me to listen too. I remember News broadcast."
He Zhiwen: "That's the secondary transformation after the local radio and television center receives the signal, and then broadcasts to nearby areas through FM frequency modulation."
Song Fei seemed to understand: "Now I can't find any station on FM, and there is no signal on TV, which means... the radio and TV systems in our city can no longer function normally?"
"Maybe even the whole province." He Zhiwen pushed his glasses, and his words were uniquely rigorous, "Although the transmission distance of FM frequency modulation is short, it may not necessarily be limited to one city, and you can often search the surrounding area." The station of the city, so…”
Needless to say, everyone understands what follows.
It's not good news, but after one disappointment after another, it's okay to be disappointed again. At least I don't have to worry about why I didn't buy a mobile phone with a built-in radio, and I also learned a lot about it.
"Student He, aren't you from the Department of Physics? Why are you so good at radio?"
He Zhiwen smiled shyly, "Hey, it's a hobby."
The smile on the already chubby face was even more naive.
Song Fei sighed that he lived and learned, and wanted to digest the other party's popular science on radio channels, but after rereading the previous conversation, he found a problem: "Wait, you said that the CCTV news you heard through FM It has gone through the secondary transformation of the local radio and television center, so how did the local radio and television receive these signals? It can’t be frequency modulation, right? Our great rivers and mountains have a vast territory, so how many relays do we have to do one by one?"
"That's why we came to you." He Zhiwen also thought it was amazing when the words came to this point. At first, he was worried that he didn't know where to start. It will be a matter of course, "If, I mean, if the country really does not give up on sending information to us survivors, then there are two most effective channels, one is radio waves, and it must be SW, short wave, which has the longest transmission distance ;The other one is the satellite TV signal, which is transmitted to the communication satellite by the ground signal base station that is still in operation, and then the satellite transmits the signal back to the ground. Both of these can be received directly without any relay of."
"No if." Song Fei said without hesitation, "We are going to turn on the TV even at the risk of being bitten, because we believe that there will be news."
He Zhiwen looked around all the students in Class 1 upon hearing the words, and found that the expressions on everyone's faces were basically similar to Song Fei's. He dare not say that he was as firm as iron, but he also had trust in his heart.
He turned to look at his three companions, and received affirmative glances.
He Zhiwen took a deep breath and finally talked about the reason for his visit: "We are just like you, and we are also eager to know the information outside. But if we want to receive short-wave signals, we must get a radio that can receive signals in this band, or directly A full-segment radio would be better. Or try to get a satellite dish with a TV, but either way, we're not going to do it alone."
"So you want to work with us?"
"right."
"Where is this radio or satellite dish?"
"can not confirm."
"..."
Song Fei was speechless, in vain excited, just wanted to complain about the lack of purpose, why did you say so much, but Zhou Yiyi asked: "Is the listening radio for the fourth and sixth grades okay?"
The eyes of the friends in Class 1 were brightened. If they were really good at listening to the radio for the fourth and sixth grades, then don’t worry, there must be several teaching buildings full of them.
"No." He Zhiwen obviously thought about this problem long ago, "The listening radios we distribute only have two bands, AF campus radio and FM frequency modulation, and can't receive other bands."
"Where's the car radio?" Qiao Siqi interrupted suddenly.
Eleven pairs of eyes glanced at the past. This proposal is not shocking, but the idea is very special.
He Zhiwen quickly came to his senses, thought for a moment, and replied: "It's hard to say, it still depends on whether the radio itself has this band. In addition, if it is the underground parking lot of our school, even if it has this band, I'm afraid it will be received." It's going to be hard."
"Are you going to smash the glass in the underground parking lot?" Zhou Yiyi couldn't think of any other tricks, unless he was lucky and encountered a fool who forgot to close the windows or lock the car door.
Qiao Siqi was puzzled: "My own car can be opened with the key, why smash the glass?"
All students: "Do you have a car at school?!"
Song Fei: "You have the car keys with you?!"
Now everyone is looking at Song Fei instead of Qiao Siqi.
The latter was embarrassed, and quickly looked at Qiao Siqi, asking questions instead of explaining: "Didn't you escape back to the dormitory, and you still have the car keys?"
"Keys, mobile phone and wallet, you can't forget these three things even if you are running for your life." Johns said that he actually took out a key ring from his trousers pocket. Keys, take a simple car key with you.
"Why do you get a car to come to school from other places?" Zhou Yilv asked on behalf of all the friends. In fact, there are not many people who come from the local area by car. Their school spirit is relatively simple, and most of the students still follow a down-to-earth and low-key style.
Qiao Siqi didn't think anything at first, but under the watchful eyes of his friends, he suddenly felt guilty, and he didn't speak very arrogantly: "Just go out on weekends, it's convenient to go to the city..."
Zhou Li's black line: "You don't have to grab a train ticket when you go home during the Chinese New Year, do you?"
Unexpectedly, Qiao Siqi shook his head violently: "No, no, no, my father won't let me drive long distances. I bought the car from us, so I just run around the city."
Zhou Lu: "After talking for a long time, what kind of car is it?"
Joskey: "The Wrangler."
Zhou Lu: "Fucking four or five million off-road vehicles, you just drive around the city?!"
Qiao Siqi: "Occasionally, I also go to the suburbs..."
Zhou Yili: "The only thing that can cure me now is you grabbing tickets with us before the winter vacation, don't tell me you don't need it."
Qiao Siqi: "My family directly helped me book the air ticket..."
Zhou Lu: "I'm hating Fu now, I want to beat him up, is there anyone together?"
All friends: "Take, get, we, us!"
