Zhang Chao nodded: "I understand." ”

"Okay, here's the meat show." Xu Haocun continued, "The firewall installed on the base station is actually a piece of hardware, so it cannot be broken through the external network. This Xinlian Building has its own base station 100%, and it must have a firewall installed, so if you want to hack into their network, you have to climb to the base station above and manually replace the firewall, and it can't attract their attention. ”

Zhang Chao asked, "Where is their base station?" ”

"Naturally, on the balcony on the top floor, it was a huge antenna-like object with a lot of alloy tubes, which was easy to recognize."

Zhang Chao said: "Okay, leave this question to me, but I don't know what a firewall looks like." ”

Xu Haocun took out a cylindrical thing from the box, it was very similar to an ancient lamp lighter, "It's this thing, Zhang Ying has already prepared it for you, you just need to bring it and replace the original firewall." ”

Xu Haocun handed the firewall to Zhang Chao's hand, and continued to remind: "You see that there are two pins under it, it is directly plugged and unplugged, and the speed when you replace the firewall cannot exceed one second, otherwise a machine downstairs will alarm the police, which will alarm the network management downstairs, at that time, he only needs to take out his mobile phone to take a look, and he can find that the key on the firewall has changed, and your whereabouts will be exposed." If you see that the string of characters above is not, this is the initial firewall key. ”

Zhang Chao's brows couldn't help frowning: "Can't it be more than a second?" ”

"Well, so, if you don't feel sure, it's best to practice first, find a random cardboard, poke two holes and practice."

"Once the firewall is off, how long does it take to find out what's going on in the building?"

Xu Haocun shook his head and said: "Turning off the firewall is only one of the steps, there is another step, maybe it may be more dangerous, I don't know if you can do it." ”

"What steps?"

"In order to improve their information security level, this kind of building was deliberately shielded from the outside signal at the beginning of construction, and people in the building, whether it is a phone or the Internet, cannot be transmitted to the outside, and of course the people inside cannot receive the signal. But they also have the need for external communication, so they will install a data sending and receiving device on each floor, and this thing, we usually call it a communication box, it is actually the second firewall. ”

Zhang Chao frowned again, "You mean there are on every floor?" ”

"Yes, it's on every floor, but you don't have to worry, it's not in the room, it's outside the floor. Oh, the first floor is in the room, but the first floor is usually a hall, so don't bother with it, just start from the second floor. They will have a signal light to indicate the location and if it is in normal use, it will flash green non-stop. ”

"What do I need to do?"

Xu Haocun picked up another thing: "This thing is familiar, it is a network cable connector, although the network cable has been eliminated, but they have been reborn elsewhere." Although this thing looks like a network cable connector on the surface, it has a very powerful overclocking signal transmitter built into it. All you need to do is find each communication box, take it apart, unplug the network cable inside it, plug this one in, and then plug the network cable into this network connector, and after doing that, the second protective wall is done. ”

"Is there a third firewall?"

"Hehe, no, just these two, as long as you get them done, my side will be very fast, no more than 3 seconds, you can call up all the monitoring data of the entire building."

Xu Haocun has seen a lot of spy blockbusters, as early as the end of the 20th century in the Common Era, there were many such blockbusters being screened in public. In the movie, those awesome agents use different means to climb to the top of the floor to complete one impossible task after another, and Xu Haocun is curious about what Zhang Chao will do.

Xu Haocun soon saw it, and he found that Zhang Chao's preparations were very sufficient. When Xu Haocun finished telling the mission goal, Zhang Chao immediately called another person, who took out two pieces of equipment: one was a silver box like a backpack, and it really had two straps on it; The other is a piece of clothing.

"What is this?" Xu Haocun asked curiously.

"These are the gadgets of our research group." The man smiled and explained, "This backpack is an anti-gravity device, and after carrying it, you can perform light skills like described in martial arts novels, and with a few days of training, you can easily jump from one building to another." ”

"This dress is called a gecko suit, it actually has a certain anti-gravity function, but anti-gravity is not its main ability, after wearing it, you can climb the wall as easily as a gecko, the glass wall is not a problem, it can also block ordinary bullets."

Xu Haocun praised sincerely: "Amazing, it will be convenient to wipe the glass after having it." ”

"Haha, Spider-Man can't afford this kind of equipment. They are also not in circulation, and so far only the military has used them among countries. ”

"Oh, you're from the research group? Dare to ask the eldest brother's surname? ”

"My name is Dai Zhicong, and you are welcome to join us, Brother Xu Haocun."

"Ahem, I was tricked in by the head of the regiment." Xu Haocun smiled bitterly.

"Haha, that's his usual style. In fact, it's good here, if you stay for a long time, you will find that although our salary is not high, the regiment commander never restricts us from spending money, as long as you have a valid reason, he can apply for you as much as you want, in this regard, it is impossible for you to do it in other civilian units. ”

They soon came to the vicinity of the Xinlian Building, but they did not approach the Xinlian Building, but drove into a building next to the Xinlian Building, the underground parking lot of the state-owned assets group.

A soldier in the parking lot greeted Zhang Chao and whispered something to him, but Zhang Chao just nodded and said nothing.

Then they went upstairs in batches and came to the 19th floor, where there were quite a few people upstairs, looking at the situation, and they were monitoring the situation in the opposite building.

Zhang Chao summoned his men to the conference room, and Dai Zhicong from the research group and Xu Haocun from the technical group were on the list at the same time, but they were asked to put all communication equipment outside the room.

"Counselor Tong, tell me about your plan of action."

"Yes, Battalion Commander."

Staff Officer Tong cleared his throat and began to speak: "Our first task in this battle is to rescue the hostages, and the second is to destroy the enemy. We will focus on surprise attacks, supplemented by strong attacks, and try not to startle the snake before the enemy finds it. According to the plan, the surrounding crowds could only be evacuated after darkness. ”

"From 6:00 p.m. to 8:00 p.m., these two hours are the time for us to evacuate the masses, and we will evacuate all the residents in all buildings within a radius of 300 meters around the Xinlian Building.

"From 8:00 to 8:30, the three companies must quickly complete the combat deployment and surround the entire Xinlian Building."

"At 8:30, the task force set off to assist the technical team to destroy the opponent's network firewall, and asked for it to be done within 20 minutes. Be careful, at this time, you must find a way to attract the attention of passers-by downstairs, and not let them focus on the Xinlian Building. ”

"At 8:50, the technical team started to act, Comrade Xu Haocun, how long will it take for you to take over the other party's network?"

Xu Haocun hurriedly said: "As long as the previous work is done, I can definitely do it within a minute." When he was in the car, he said that he could do it in three seconds, but at this time, he felt that he couldn't talk too much, so he temporarily changed it to one minute.

Counselor Tong said: "Give you 10 minutes, if possible, I want you to intercept the other party's communication equipment, if the other party is talking to someone outside, I want to know what they said." ”

"Ahh Xu Haocun hurriedly went out and hugged the box prepared by Zhang Ying in, "That, Team Leader Zhang Ying has prepared a box of micro monitoring equipment, it has magnetic adsorption, when you install the network cable connector, you only need to adsorb it on the communication box, so that no matter who you call inside, you can monitor." But this thing is super power-hungry, I just looked at the manual in the car, and it only works for two hours. ”

"Okay, thank you, please take a seat." Staff Officer Tong continued: "After the work of the technical team is completed, at 9 o'clock in the evening, the road will be blocked, the street will be cleared, and the local police will cooperate with our operation. The attack was launched on time at 21:15. ”

"In this operation, the first company was responsible for attacking from the ground, and the second company was responsible for responding to emergencies and was ready to rescue at any time. Snipers must always monitor the opposite window upstairs, if they find that the enemy is firing missiles from the window, they must be sniped to stop them at the first time, and they cannot be successfully launched, this is an urban area, and the damage that missiles can cause is too great, and we can't let this city suffer such a huge loss because of our actions. The Third Company is responsible for the aftermath and must intercept all the enemy's vehicles and flying vehicles and not let them escape. ”

Zhang Chao spoke in a timely manner: "The second company still has a task, to protect the two comrades of the scientific research group and the technical group, they have no combat effectiveness, and you must not let them suffer any damage. Second Company Commander, what do you think of letting Li Youcai, the third squad leader, lead the team to stay behind to protect the two of them? ”

He did not give an order, but asked the second company commander for his opinion in a consultative tone, which was considered a personal suggestion, if the second company commander really did not agree, he would not insist, as long as the second company could complete the task of protecting the target.

A handsome young man wearing glasses stood up and said, "Report to the battalion commander, I have no opinion." ”

The Gray Wolves secret base.

Because Meng Qingxiao was not allowed to join, he was still depressed, and ran to the crazy sandbag on the rooftop, when Xu Haocun from another world ran over and said to him sneakily: "Follow me." ”

"What?"

"You'll know when you come."

The two came to Zhang Ying's office, where Zhang Ying and Meng Yuxin were staring at the computer screen, not knowing what they were looking at.

Meng Qingxiao came up, his eyes widened suddenly, and he exclaimed, "Damn, how did you do it?" ”
