The five of them huddled in the "digital integrated communication" hut, and they didn't dare to come out. Although the four black-clothed people have been on missions with Yang Xiaohai, how have they ever seen such a scene? They all stared at Yang Xiaohai with panicked expressions. And he was attracted to a gray cabinet. The front of the cabinet is a layer of panels with many bulges.

Yang Xiaohai looked at this thing, and then thought of the name of the room of "Digital Integrated Communication", and seemed to guess the purpose. He asked in a breathless voice, "What do you do with this thing?" "Four black-clothed, you look at me, I look at you, but no one has spoken. Yang Xiaohai glanced at a few people a little sternly.

"Team Li, I have to ask Cortana about communication equipment. She's in charge of this. ”

"Oh? I remember she was doing the recording and the process, huh?" Well, that's her job too. ”

“…… What the hell is she doing? ”

"It's hard to say, except for the field, she has a share in other jobs."

"She's a woman."

"Hehe, in the black-clothed team, it is the norm to use women as men."

"What about the old men?" Yang Xiaohai squinted, a little annoyed.

"Men? Men as animals! The answer was natural, but he didn't control his voice. The "infected" on the first floor were agitated, startling the neck of the person who spoke.

In addition to the cabinet standing in the corner, there are also a variety of equipment placed around, and he is not a famous one. Yang Xiaohai touched this and that from time to time. It seems random, but when it falls in the eyes of the four black-clothed people who are hairy in their hearts, it is strange everywhere

。 His movements were obviously very fast, but he didn't make a sound at all. If you close your eyes, you will think that there are only four people in the room. After tinkering for a long time, Yang Xiaohai had to give up, these things were not something he could understand. After searching for a long time, it was not for nothing. At least two wireless walkie-talkies and three chargers were found.

He shoved them into his pocket. Speaking of this pocket, I only recently put it on my back. There were infected people on every floor before, and Yang Xiaohai was too lazy to carry it. The fifth floor began to be a little more relaxed, and Yang Xiaohai put the deerskin backpack on his shoulder. It only took two days to memorize it and it came in handy.

It's just that it was just used to hold the arms of the infected, and immediately came to install the walkie-talkie, which is a little bit of a channel. And he's the only one who has nothing to do and wander around with his arms behind his back.

After packing his backpack, Yang Xiaohai pulled his hand on his mouth, signaled everyone to be quiet, and then pulled the door open. Yang Xiaohai pressed the wooden door and tilted his head towards the four black-clothed people who were stunned. The latter just woke up from a dream and walked out of the room lightly. After a while, Yang Xiaohai returned to the 3rd floor from the west staircase.

Splitting his head and asked Yan Bing, who greeted him, "There is a 'digital integrated communication' downstairs, what is that thing for?" Yan Bing didn't answer and asked, "The thing is still there?" Can it still be used? "What's that?" There's a lot of equipment there, anyway. Whether it can be used or not, you have to try it to know. By the way, those things are for communication, right? ”

Yang Xiaohai asked again. This time, Yan Bing replied to him: "Last year, I entered a set of base station equipment, which is the same machine you saw. It is mainly responsible for the communication and networking of the whole city. Cortana knows the specifics. Yan Bing chatted calmly, completely forgetting the friction of the previous few days.

"Without further ado, who's going to bring Cortana. Go now, and be sure to find out what's going on in the communications room. ”

"Don't bother everyone. Just me and Wang Xiaona, the smaller the target, the safer. "Oh?" Yan Bing was puzzled. So Yang Xiaohai told the situation on the first floor. With the description, a dense crowd of "infected" unfolded in the minds of the people.

Not only Yan Bing, but everyone else fell silent. Everyone is thinking about it, but these have nothing to do with Yang Xiaohai. Wang Xiaona separated from the outermost layer of the crowd and pushed the black clothes to Yan Bing. Still wearing a black uniform, but much more decent. Seeing Wang Xiaona, who was dressed from top to bottom, Yang Xiaohai's mood suddenly improved a lot.

He teased: "Do you have the courage to go on another mission with me?" "Wang Xiaona is not as casual as him. She stood in front of Yan Bing, quietly waiting for orders.

"Thank you, take a look at the communication equipment. If you can, try to contact the province. I wish you success. ”

"Yes!" Wang Xiaona answered very simply.

"In addition, you also heard District Chief Li's words, the situation on the first floor is very serious. In addition to staying quiet, you should also listen to Team Lee's advice. That's all I can think of, for the survival of everyone, it's hard work. ”

"Guaranteed to complete the mission!" Wang Xiaona still replied crisply.

And Yang Xiaohai lazily had a different opinion: "The emperor is not a hungry soldier, come to some real ......" One paw stretched out, and the three fingers rubbed a few times. Yan Bing's face suddenly darkened. His lips squirmed a few times, but he didn't say anything.

Counting this time, this is the third field mission. Wang Xiaona is the person who has been out in the field the most times except for Yang Xiaohai. The bitterness was not in vain, and when she saw the dense "infected people" downstairs, she returned to normal after a brief loss of consciousness.

She walked briskly, the black tourist shoes under her feet silent. In the blink of an eye, the two of them pushed open the wooden door with the sign "Digital Integrated Communication". Entering the room, Wang Xiaona took out a group seal from behind a machine. The seal is sticky. She pasted it very carefully, and only after the four door seams were all pasted on did she pat the dust on her hands and body.

Yang Xiaohai thought she was done, but she turned around and took out a rag from the bottom of a machine shell and wiped the table and chairs. During the whole process, Yang Xiaohai didn't talk much, and Wang Xiaona didn't think to explain. A chair, just a simple wipe of the dust, it doesn't take much time.

After Wang Xiaona moved the chair to the cabinet and took out a whole set of tools from the ground like a trick, Yang Xiaohai finally couldn't hold back.

"You know this place well?" Yang Xiaohai asked in a low voice. "Of course, this is where I work." Wang Xiaona took the plum blossom screwdriver and removed the screws on the back cover of the cabinet little by little, and her movements were very skillful.

"What the hell is this?" Yang Xiaohai continued to ask in a whisper, while holding the slightly shaking cabinet with both hands. "Don't be so careful, the sealing strip is sound and heat insulation, and it works very well."

Wang Xiaona said in a normal voice. Yang Xiaohai immediately put his ear on the door. Except for the sound of the two breathing, there was silence outside the door.

Yang Xiaohai blamed her and said: "Stupid, bold and brave are separated by a layer of window paper." If it causes a strange tide, you won't have time to cry. ”

Wang Xiaona shrugged her shoulders apologetically, tilted her head, and whispered while sorting out the messy wires: "The BF-9500 base station adopts a modular unit design, which is reliable and scalable, and has its own powerful and rich business functions, and at the same time supports multi-level fault weakening mode. The base station can independently handle the call in the station, which effectively improves the reliability and efficiency of the product. Backup mechanisms are used for key hardware components, such as base station controller backup, cluster master control channel backup, NE link backup, etc.......

"Stop, stop, stop...... Don't endorse, talk about people! Yang Xiaohai didn't listen to a word.

"Simply put, it's a wireless base station. Do you know this wireless base station? ”

"I don't understand!"

"I know you don't understand."

Wang Xiaona sighed helplessly, and then said: "Just use it as a signal tower." It's not quite accurate, but it's understandable. ”

"What's the use of that?" Yang Xiaohai was still confused.

"It can send a message to any terminal, even a human voice call. Ah, why are you hitting me? Wang Xiaona covered her head and raised her head in confusion.

Yang Xiaohai withdrew the knife hanging over her head and said softly: "Speak human words." Drag the text again, be careful that I hit you with a full head! "Not accurate enough? Yes. Let's put it this way, it can call the intercom in black all over the city, and it can also contact the base station in the province. His greatest function is communication, connecting messages from far, far away. Do you understand that? ”

"Cut, isn't it just a big call machine, what's there?" said it so simply, if you don't understand Yang Xiaohai, you will really become an idiot.

He stared at the many protrusions on the cabinet and asked curiously, "What are these?" "Well, this is the splitter, and the top is the fan control unit, the power management unit, ......"

"Okay, okay, you're busy with yours, take care of me. I'll look at the scenery first. ”

Through the small window on the wall, Yang Xiaohai cast his eyes outside the building. The weather was nice today, and there was a light rain in the early morning. The messy world was washed away by the rain, and the distant scenery became clearer. A building as tall as the security building, but even taller, unfolded before his eyes. The whole building is gray and white, and it looks calm and atmospheric.

The whole structure is trapezoidal, but the two sides extend forward, like the two arms of a person. With the square in front of the upper floor, it is more magnificent and dignified. It's just that most of the windows are broken, and there are traces of fireworks everywhere. Yang Xiaohai had heard of it upstairs, it was the center of Huabai City-Huabai City Branch Building. Judging by the dilapidated appearance, the branch building is much worse than the security building.

After looking at it for a while, Yang Xiaohai withdrew his gaze. He had seen enough of the unchanging scenery. Under Wang Xiaona's encouragement, the gray cabinet finally came to life. Not only did the red and green lights flicker, but even the ground trembled slightly. Yang Xiaohai's expression tightened, and as soon as he wanted to move, Wang Xiaona pulled out a few plugs, and the trembling disappeared immediately.

Yang Xiaohai patted Wang Xiaona's shoulder, but she knocked her off. Dragged a keyboard from the corner and pressed a few times to stare at a lit monitor. Three large letters "S-O-S" appeared on the screen! Then Wang Xiaona operated a few more times, and then leaned back on the back of the chair as if relieved.

"I sent the distress signal. Whether it's useful or not, it depends on whether God appreciates the face or not. Wang Xiaona made a fist with her right hand and hammered her sore shoulder.

Yang Xiaohai asked puzzledly: "You don't know the result?" "As usual, as soon as the message is sent, it will be received by the province immediately. You saw it, but you didn't reply. Maybe there will be a response after a while. The whole world is infected, and I don't think the situation of the provincial company is optimistic. ”

"Didn't you just say that you can contact the walkie-talkie of the city's company? It's okay to be idle, neatly. ”
