Chapter 641 Is the Hemorrhoids Cured?

Near noon, Ji and Yue finally checked the last point, but naturally they still didn't find the outcome.

It seems that they will finish checking it all in two or three days at the earliest and four or five days at the latest.

If you can't catch it by then, you can sum it up and leave.

"You go to another district and call me if you have anything." Bai Song originally wanted to ask them to have lunch, but Ji Yue and others had to go to a meeting again, so Bai Song didn't stay.

There is really nothing we can do about this matter, as most cases in the world are like this.

A fish enters a ditch in muddy water, how do you catch it?

Drain the pool - check them one by one;

Use the net to fish over and over again - screening;

Fishing with a fishhook - luring enemies to appear;

Use high technology to track - technical reconnaissance;

Install fixed-point sensors-monitoring video

Actually, there is not much difference.

It's just that some pools are too big and the water is too muddy to catch.

Some ponds are too big to be drained, so it is impossible to catch 100% of the fish using other methods.

Of course, someone said, is it okay to pour medicine into the pool?

Okay, converted into reality, this is called nuclear bombs.

Whether the effect is good or not, whoever uses it knows.

Leaving here, on the way to Tiannan District, Bai Song received a call from Liu Shuyuan.

"Is it convenient for you to answer the phone?" Liu Shuyuan asked.

Bai Song didn't drive, but was taking the subway. "It's not convenient, there are people around."

"Did you go to the bar? Is it so noisy? Oh, oh, oh, subway." Liu Shuyuan heard the station announcement on the other side of the phone, and then said: "Do you have headphones?"

"Yes, I'll put them on." Bai Song took out the headphones from his pocket.

"Get off the bus at the next stop, find a place where no one is around, put on headphones and talk to me," Liu Shuyuan said.

"Where is there no one in the subway station?" Bai Song was speechless.

"Okay, don't say what you shouldn't say. Put on your headphones and listen to me. Just express yourself casually. I can understand you." Liu Shuyuan said.

"Okay." Bai Song put on the headphones.

"Do you still have strong connections in Tianhua City?" Liu Shuyuan asked: "If you do, just tell me. Don't hide it at this time. I have run out of recruits to get you to the city bureau."

"That's true. Everyone I know knows that." Bai Song said.

"Is Ma Donglai the biggest leader you know?"

"The relationship is good, that's it."

"Okay, I believe you. Then let me ask you, do you know the previous Director Zheng of the Criminal Investigation Bureau?"

"know."

"Damn, retirement doesn't count! Why didn't you mention this?"

"I've only met twice, just acquaintance."

"Ah?" Liu Shuyuan was a little confused: "He even mentioned your name during the discussion at the city bureau today."

"I met him this morning. Maybe he was in a good mood."

"Well, that's the case. These old leaders, especially those at the department and bureau level, have recently been called back to study. Of course, they have not made any mistakes. They are all former bosses with great talents all over the world. Although they are coming back to study, But studying can only be part of it, and the Municipal Bureau also has to express condolences." Liu Shuyuan said: "We also held a condolence meeting in the morning. During this period, during the chat, Director Zheng talked about you and praised you."

"Ah?" Bai Song was also stunned for a moment. Could it be that he had discovered his talent?

"At their level, even if they retire, they won't talk nonsense." Liu Shuyuan told Bai Song, "Ju Zheng is Ma Donglai's master."

"!" Bai Song knew what was going on.

I'm afraid Ma Donglai also talked about him when he visited Bureau Zheng. Bureau Zheng is also interested in some big cases. This has been a habit for decades. Therefore, when Ma Donglai goes to Bureau Zheng, Bureau Zheng will definitely ask. In the major cases in Jiuhe District in the past two years, Bai Song was more or less involved.

No wonder Bureau Zheng called out Bai Song's name right away, that's what happened!

"Is that a good thing or a bad thing for me?" Bai Song didn't understand what was going on.

"Of course it's a good thing." Liu Shuyuan said: "A compliment from the boss is more useful than ten reports written by your director. Especially at this juncture, these retired old leaders actually don't talk nonsense, but they show it. is you."

Liu Shuyuan paused: "The rest is up to you to show some real skills."

"Okay, thank you, I understand." Bai Song hung up the phone and secretly admired him.

This network of interpersonal relationships is too complicated, and Liu Shuyuan even knows this, he is really awesome!

So, now, it’s time to bet your luck!

Most detective novels use reasoning to find out who the murderer is. Then, the murderer is nearby and can be caught immediately.

But what if the killer escapes? Can you figure out where the murderer is by reasoning?

It is possible in a short time, but after eight years of running, it is impossible. This is not something that detective novels can solve.

Some things can only rely on persistent efforts and collaboration.

However, Bai Song didn't know that this matter was so difficult!

There are really a lot of dirty and messy places in these two districts.

Many people are used to seeing tall office buildings and bustling lights, but they don't know that any city, even an urban area, still has such places.

Not to mention Tianhua City, even in Shangjing and Magic City, apart from the core areas, there are also many such places in other areas.

Moreover, such places have a common feature - many passages.

Some Tongzilou communities have a large corridor on the first floor, dozens of households on the first floor, and dozens of passages outside the community.

Nowadays, surveillance has become more and more complete, so the number of surveillance in these places is staggering.

In the past few days, Sun Jie must go back to prepare for the wedding. He will be married on Saturday. Bai Song and Wang Liang never stopped for a moment and kept adjusting the video everywhere.

It was too difficult for just the two of them.

A few days later, on Friday night, Bai Song and Wang Liang were together again, processing hundreds of gigabytes of video that had been copied from more than a dozen video points today, and then using software to compare.

People are busy during the day, retrieving data for the day. The computer was busy all night and compared automatically.

"When will there be a fully automatic face comparison system?" Bai Song sighed.

"Technically, it's still not up to the mark, right? Unless every camera is equipped with optical fiber to the headquarters, for more convenience, it's actually best to use wireless transmission in an encrypted frequency band. But now the cameras are becoming more and more high-definition. There are thirty or forty of these in one community. For cameras, the amount of data per second is more than 10MB, and the current 4G network is still unable to support it. Moreover, the video definition will become higher and higher, and the data will become larger and larger." Wang Liang said: "Now it can only We can do some pilot work to a certain extent, but there are some difficulties when it comes to citizens’ privacy.”

"Well, unless there is a faster transmission protocol." Bai Song nodded, "But for this kind of big data transmission, confidentiality is still the first priority. I don't know which country can be the first to break through in the future. Use your own talents. Most assured.”

"It's not bad. At present, short-distance transmission through wireless networks or wired transmission are still more common. Faster transmission protocols require greater base station density, and the rates will not be cheap in the short term." Wang Liang said as he spoke, While operating the computer skillfully.

Bai Song didn't bother him. After a while, he pointed to the mobile phone on Wang Liang's desk: "Your mobile phone rang."

"Help me pick it up." Wang Liang was operating the computer.

Turning on the phone, Bai Song heard a familiar voice: "Wang Liang, your hemorrhoids are not cured yet, are they?"
