Shi Lei received a gold vein worth 52 billion Xia Guoyuan from the internal network of the National Security Bureau of South Vietnam. According to the truth, Shi Lei should be very happy. In fact, Shi Lei did not feel too happy.

This gold material with a value of 52 billion Xia Guoyuan was placed in front of Shi Lei, which gave Shi Lei an illusion that Nan Yueguo deliberately gave him.

Why do you say that?

Why is such an important information only placed in the third level of confidential space? It can be placed in a higher level of confidential space, giving more stringent protection.

Not only that, the data of this gold vein, the encryption method is only ordinary long password encryption, which makes Shi Lei very puzzled. According to the value of this information, it is definitely worth using a special encryption scheme, and it is worthwhile to develop an encryption scheme for it alone.

‘Is this a false information? ‘Shi Lei secretly guessed the true and false of this information. If this is a false information, and the South Vietnamese country arranges a spy in the corresponding area, isn’t it a carefully arranged fishing trap?

As long as someone goes to the relevant area to investigate, it is appropriate to get the information of the gold veins, and the South Vietnamese country can also find the culprit invading the South Vietnamese National Security Bureau.

Shi Lei thinks that this possibility is more and more, but Shi Lei can't understand why the Nanyue National Security Administration can do such a detailed information in such a short period of time. After all, Shi Lei analyzed the file. The date of creation of this document was not created, but was created for more than a year. And, the last modification time is also half a year ago.

The file creation time and file modification time can be modified by some special means. The way Shi Lei investigates is different from the normal way. If the time is modified, Shi Lei can query it. The current situation is that the creation time and modification time of the file are completely normal, and there is no flaw at all.

Shi Lei did not believe that someone modified the file creation time and modification time, he would not find it.

If this document is a false document, then the head of the South Vietnamese National Security Agency, their main occupation is a network security expert, is the assistant astrologer, or a prophet?

Otherwise, why did you prepare this document as early as a year ago?

Judging from the file creation time and file modification time, Shi Lei has a reason to believe that this document is true. However, the South Vietnamese National Security Agency, how to deal with this highly valuable confidential document, is so rash?

‘What are the meanings of the hangovers of the South Vietnamese countries? ‘Shi Lei secretly guessed in his heart.

"Jie Shier, extract the time node in the gold vein file data, from the beginning of the file creation, according to the time of the previous document modification as a node, make a timeline!" Shi Lei commanded the clothes.

Shi Lei can investigate every time the file is modified. According to these time points, Shi Lei can make a timeline. Then according to this timeline, Shi Lei can investigate further.

“Sir, the timeline is finished.” Yi Zhuer reminded Shi Lei.

After a little thought about it, Shi Lei told the singer: "The clothes are marked, the location of the gold veins is marked, and the location of the gold veins is centered to retrieve all the roads that can reach the gold veins."

The location of the gold vein is located on the border of the South Vietnam and Xia countries, and most of the gold veins are distributed in the territory of Xia. The South Vietnamese country’s exploration team is unlikely to travel by helicopter. Because the South Vietnamese country's helicopter is close to the Xiaguo border, it will definitely be warned by Xia Guo, and even will be provoked by Xia Guo.

The South Vietnamese country's exploration team will not choose the way to walk. The equipment needed to detect the gold veins is obviously unscientific if it relies on human shoulders to pick up the back.

Only the highway channel is the way that the South Vietnamese country exploration team may choose!

In accordance with Shi Lei’s instructions, Yi Zhuer marked the possible route information on the map displayed by the projector. However, the gold veins belong to remote areas, and the nearest road is also about ten kilometers.

Shi Lei brows slightly wrinkled, ‘10 kilometers away? This is not too far! ’

“Well, search all surveillance cameras of possible routes, extract all surveillance videos, query the timeline, monitor the recorded driving records, analyze the license plate number, and record the duplicated license plate numbers.” Shi Lei told the smugglers, let The basic analysis of the clothes.

What Shi Lei just told is definitely a very troublesome thing. If you let humans do this, don't say how much manpower you need to consume. Let's talk about whether humans will make mistakes. Mankind usually makes mistakes when performing such boring work.

In the execution of Shi Lei’s order, Yizhe first finds the line that meets the conditions, and then inquires about the surveillance camera that is owned along the corresponding line. This work consumed some time, and after about five minutes, he gave feedback to Shi Lei, indicating that the work was completed.

"Sir, because of the long time, only some of the surveillance video records were queried, and the monitoring records of some time points could not be found." Yi Zhuer responded to Shi Lei.

Shi Lei nodded, "Continue to analyze the next step!"

The surveillance video recorded by Yizhe began to be searched from all the surveillance video videos to find the license plates that appeared repeatedly in the timeline.

When Yi Juer was comparing information, Shi Lei did not idle. Shi Lei was optimizing the ‘Deep Recovery’ software. This software is the guy who Shi Lei spent all his life eating! In the past life, Shi Lei mainly relied on the recovery of data to obtain living expenses, as well as college tuition.

Nearly half an hour later, I have finally completed the data comparison, but the results are not very good!

“Sir, starting from the starting point of the timeline, ending the end point, monitoring the video recording in the timeline, and not finding the license plate number repeated three times or more. There are four vehicles with two license plate numbers repeated. Two of them are In small cars, according to the number plate survey, the two cars are vehicles in the Xiaguo area. The owner is a Xiaguo citizen and has used a tourist visa to enter the South Vietnamese country."

Yi Shier continued to introduce the situation. "The other two vehicles, one of which is the vehicle of the South Vietnamese National Army, is analyzed from the license plate number and is a military jeep. The other is a large transport vehicle. There is no suspect. The monitoring record is no more. More information is recorded, and it is impossible to judge more situations."

Shi Lei smiled and said: "Yu Zheer, update the subsystem's 'depth recovery', the update plan has been completed." Shi Lei will optimize the depth recovery software, so that the update is loaded into the main system.

“Sir, the update is complete.” The company quickly updated the deep recovery system.

"Jie Zheer, start the deep recovery system, will just check, delete the history of the surveillance camera, use the deep recovery subsystem, restore the history." Shi Lei once again told the clothes, let the clothes first recover Security monitoring camera history data.

The history of the security surveillance camera is saved in the corresponding hard disk device. Although the history record is deleted, the bottom layer in the hard disk can still extract the deleted record.

This kind of history will not be erased at all, unless it is repeatedly low-level formatted, it will be erased. If it's just advanced formatting, it's impossible to succeed.

Shi Lei optimizes the depth recovery software to restore the record of the security surveillance camera and thus determine more information. It’s more than half an hour later, it’s already more than two in the morning on June 4, and Shi Lei’s sleep seems to have all come to mind.

Before Shi Lei fell asleep, the clothes were finally analyzed again. This time, Yizhe got a fairly complete monitoring record and recorded it through matching. Three of the vans appeared seven times in the timeline.

"Is the identity of the three vans found?" Shi Lei asked.

On the projector, the clothes of the three vans were all projected out. Shi Lei looked at the identity of the three people and found no other party.

‘It’s weird, this is not right! ‘Shi Lei’s heart is thinking in secret. “Well, do you have a car GPS system for these three vans?”

In the afterlife, the average vehicle has a car GPS system. In 2007, most vehicles did not have a GPS global positioning system.

"Sir, the three vans of the target, all without car GPS navigation." Yi Zhuer returned to Shi Lei.

Shi Lei is a bit depressed. If the three vans in the clothes have a GPS global positioning system, then Shi Lei can log in to the three-pole management authority of the global positioning system to investigate the driving records of the three cars.

As long as you check the driving records of the three cars, you can know if they have been to the vicinity of the gold vein. If the three vans have been to the vicinity of the gold veins and have been there many times, then it is natural to prove that there are at least suspected conditions near the gold veins, not something that the South Vietnamese National Security Agency has pulled out.

The target vehicles that have been compared by the license plate, without the GPS global positioning system, can not know their trajectory records, naturally they can not know whether they are close to the gold vein.

‘Damn, this information is really fake! ‘Shi Lei’s heart is a little roaring. If this is a fake material, Shi Lei will not lightly patrol the South Vietnamese country.

If this is a true information, Shi Lei will use this information to find a suitable advantage for himself.

"Jie Shier, check, the nearest surveillance camera from the gold vein, in what position?" Shi Lei asked about the clothes.

I was immediately replied, "Sir, the closest surveillance camera to the gold vein, more than 20 kilometers."

"Idiot clothes, it seems that only another way to determine the results!" Shi Lei has another method in mind, but that method is somewhat dangerous....
