Annihilation of the solar system

Cao Rui and Zhang Jie led the technical team to He Zhengping's residence avoiding surveillance cameras along the way. They opened the union webpage, web games and union chat room according to He Zhengping's instructions. Fortunately, they found that the three webpages

All can be used normally. The subtitles in the union chat room are still refreshing.

"Can you locate the server location immediately?" Cao Rui asked.

The people in the technical team tinkered with several computers for a while, and the team leader spread his hands helplessly:

"Their hacking skills are very sophisticated and they cannot track the exact location. But with such a large scope and amount of information, they should have set up a private server, otherwise we would not have been unaware of it."

"Is there any way to know their approximate location?" Cao Rui asked.

"Based on the estimated proportion of union members provided by Xiao He and the information transmission volume of these three programs, I roughly simulated the information magnitude of information upload and download. After screening and comparing the overall information volume, I think the location of this server should be

Just inside Shancheng City." said the technical team leader.

Cao Rui asked again:

"How confident are you in this estimate?"

The technical captain smiled:

"I can't say with certainty, but in the context of the rapid decline of network information in the crisis era, the conclusion drawn by my method still has certain reference value. However, it is impossible to pinpoint it accurately."

Cao Rui held his stubble-covered chin and thought for a while:

"I have a stupid way. If the connection between the server terminal and the client is interrupted, there will be a very brief connection interruption. Is there any way for both parties to detect it?"

The technical team leader replied:

"If it is very short, such as within 1-2 seconds, it will be difficult to detect. Because such a short network delay is normal under current network conditions. But it can also be detected using network delay monitoring software."

Cao Rui clapped his hands and said:

"Well, we can confirm whether your guess is correct right away."

Then turned to Zhang Jie:

"Immediately contact the people in the field team to go to the network data center. Ask them to create a 1-2 second network interruption between Shancheng City and the outside Internet. If you can't handle it technically, ask professionals to figure out how to do it.

Take action and do your makeup well, don’t miss anything.”

"Understood! Director Cao!" Zhang Jie immediately started the deployment through the radio.

Half an hour later, news came over the radio that the field team would cut off the hard connection between Shancheng City and the outside world in 120 seconds, which lasted for 1.5 seconds. Cao Rui and the technical team were all staring at the ping screen.

The computer screen is worth counting down silently in my mind.

"The network disconnection has been completed, lasting 1.25 seconds" came the voice of the field team on the radio.

Cao Rui, Zhang Jie and the technical team all looked at each other.

"There is no change in the ping value," the technical team leader said.

"That is to say, their server is in Shancheng City!" Zhang Jie exclaimed.

"Then it's easy to handle. Just use this stupid method and let the people in the field team do it. The scope of the network disconnection is reduced to the administrative area and the base station. In the end, we can always find these guys!"

"I'll make arrangements immediately!" Zhang Jie replied.

Cao Rui stopped Zhang Jie who turned around:

"Be sure to use makeup to hide it, especially the smaller the area. The higher their vigilance, so be careful! You can't be discovered!"

"knew!"

Although Cao Rui's method of locating the location of the server by temporarily disconnecting the network is clumsy and inefficient, it is also the best method in the face of the omnipotent "ghost" on the Internet.

The night gradually deepened, Cao Rui checked the time, and He Zhengping still hadn't come back. The chat room was still very lively, and from time to time, several surveillance photos of the strike wave in various places appeared.

"They are making a lot of noise. This will distract them, which is a good thing for us." Cao Rui said to the technical team.

"The investigation has been carried out to a street-sized area, and the results should be available soon. I hope all goes well for the brothers in the field team," the technical team leader said.

At this time, Zhang Jie hurriedly walked in with a few photos in her hand:

"Found their server location!"

Cao Rui took the information from Zhang Jie's hand. The photo showed a seven or eight-story building, which looked like a school building.

Zhang Jie gasped slightly:

"This is a radio and television university in Jiangnan District. Before the crisis era, it was mainly engaged in online education and academic qualification improvement. After the crisis era, the school's main business was suspended. And the school's location is far away from the industrial area.

It has not been requisitioned and is temporarily idle.

I checked, and the building in the photo is the school’s computer room, and there used to be a large number of network servers here. If they hadn’t been requisitioned, those servers should still be there.”

"Were you not discovered during the investigation?" Cao Rui asked.

"Probably not. I was just about to talk to you about this issue. Look at these photos. They were all taken with a high-magnification telescope on a building in the distance." Zhang Jie pointed to the partial photos.

In the close-up photo, you can see a black square tablet placed on the roof and several windows, with an antenna-like thing protruding from the bottom of the tablet. Zhang Jie pointed to the device.

"We retrieved information from the Equipment Department. This is a short-range warning radar called 'Hongying'. It was originally used as a search radar for the warship near-defense system. This system can detect small moving targets within 20 kilometers.

It is very sensitive. I have read the test report and the 'Hongying' radar can even detect the incoming 60 mortar shells instantly."

"That means we can't get close from the air?" Cao Rui asked, looking at the photos.

Zhang Jie frowned and said:

"It's basically impossible. That building is on campus, surrounded by greenery, playgrounds, and low-rise buildings. Their location was very tricky. Moreover, our field team has already investigated it, and the ground is covered with surveillance cameras. It's basically impossible.

It's possible to approach the building without being discovered."

Cao Rui repeatedly looked at the photos taken from various angles and said seriously:

"Such strict security, and look at the highly confidential photos and highly technical words in the chat room. I'm afraid there are more than just their believers in this building."

Zhang Jie was shocked:

"you mean....?"

Cao Rui interrupted Zhang Jie:

"It's hard to say now. We won't know until we go in."

Zhang Jie understood what Cao Rui meant. Not many people know about the concept of Rain Man now. She went on to say:

"But they are so heavily guarded. I'm afraid that by the time we rush in, they will have already run away. And I have checked that there is a municipal stormwater pipe under this building. The rainwater pipes in southern cities are very thick, and even a sports car will have no problem."

"

Cao Rui spread the photos on the bed, looked at them for a long time, and said:

"If you can't approach covertly, you'll have to resort to rough means. You have to capture them alive, and at least get some useful information."

"Director Cao, what do you mean?" Everyone looked at Cao Rui.

"I think the battle in Guangling County in the past few days will probably not be resolved unless the big leaders come forward. The special plane came with the escort fighter jets. Xiao Zhao, please contact the Air Force and ask them to start from tonight.

Send fighter planes to fly over the sky near this building every three or four hours. It is best to turn on the afterburner and make the sound loud. Please keep it confidential."

"I'll do it right away. But will there be too much noise?" Xiao Zhao said.

"What you need is to make a lot of noise for them to notice." Cao Rui replied.

"Zhang Jie, take people to the underground rainwater pipe immediately and don't get close to the building. Seal it with a grid in the pipe network around the building and guard the exit." Cao Rui gave an order to Zhang Jie.

.

"Yes, I will go immediately." Zhang Jie replied.

"The others put on their equipment and followed me to the safe point closest to the building to stand by."

After assigning the task, everyone looked at Cao Rui in confusion, not knowing what his plan was. But this is also a basic rule of field tasks. You only need to know the content of your own task, not the details of the entire task. Cao Rui

Rui's face looked confident. He picked up the high-frequency radio and said:

"I still have to contact my friends in the Army."

Then he walked out of the room leisurely.
