As soon as Da Ben arrived at Yongxing International Airport in Sushan District, Li Bai's cell phone rang.

Reduce speed, pull over, stop, and pick up your phone.

The caller ID is Lao Li. Although Li Bai opened it very quickly, the old man still arrived earlier than the planned landing time.

Flights often come late, and it is not uncommon to arrive early.

The old man called the phone on the plane that had just landed. Li Bai drove over now and was just in time to get out of the station.

There is a tall ceiling at the entrance of the station, blocking the rain.

Li Bai saw Director Li standing by the roadside leisurely smoking a cigarette from a distance.

Before boarding the plane security check, you have to throw away the lighter and you can only bring a cigarette to board the plane. However, when you come out, you can pick up the lighter left by someone else.

Lao Li picked up a high-end product with oil, and while smoking, he was shaking his lighter and playing tricks.

The Benz slowly stopped beside the curb, and Li Bai lowered the window of the passenger seat and shouted.

"Dad! Get in the car!"

"Wait for my last bite!"

When Lao Li saw his son arrive on time, he smiled and put away the lighter that was spinning in his hand, took a sip, drowned the cigarette butt in the water stains on the side of the road, and then flipped it casually.

The cigarette butts drew a parabola and accurately landed into the recyclable trash can seven or eight meters away.

Please remember: cigarette butts are dry garbage. Don’t let others ask you what kind of garbage you are?

Lao Li didn't bring much luggage, except for a 26-inch suitcase and a hooded coat hanging on the box, the rest were basically empty.

It can only be said that it is basic. After all, there was a lighter and a cigarette with one hand just now. Now that I put the lighter back in my pocket, I am officially empty-handed.

There are no specialties in Huima County, and the bureau chief is also very poor. This time I came here to eat my son, so I feel at ease.

After throwing his big suitcase into the trunk of Da Ben, Director Li took his hooded coat and got into his son's car. The coat was thrown into the back seat, and the person sat in the passenger seat.

After the old man fastened his seat belt, Li Bai stepped on the accelerator.

Huxi City has strict public transportation management. If you don’t wear a seat belt or drive and call, you will get a ticket. There is no need for traffic police to take action. The surveillance camera on the road can be photographed clearly.

"Dad, why are you free to have a holiday this year?"

Li Bai hasn't seen an old man having a Spring Festival holiday since he was a child, and this is the first time in the past two years.

The special brigade is already busy with business, and the combat personnel have no more tasks and must set off at any time. Logistics personnel must be on standby and ready to provide service support. There is basically no time to spare.

After relocating to the local area, he was a place where people were not shit, and the people were tough and cases were frequently broken. Not to mention long holidays, there was no daily double break or even single break, and there was no rest for 365 days all year round.

It was not until this year that this time, and all of them were blessed by technology.

"We have already used black technology, so it's time for us old cabbage bandits to retreat to the second line."

Lao Li sighed that the technological progress now is so fast that it is scary. In a blink of an eye, their generation is out of date.

The old seniors also said that they could no longer keep up with the situation, but they didn't expect that in the blink of an eye, they fell on Li Wei and others.

"What black technology? Are combat robots?"

Li Bai is engaged in medical work, and he has made every step in the field of medicine, and there is no shortcut to take, so he is not sensitive to the ever-changing high-tech.

The old antique roentgen rays are still in use today and have decades of history.

Two hundred years have passed, and the stethoscope is still in use.

It has been two thousand years since traditional Chinese medicine still uses the vision, hearing, and questioning.

The drug was just developed and it was not launched on the market immediately.

Therefore, medicine is not so sensitive to new technologies. After all, what we need is maturity and stability rather than advanced.

"Haha, why would you think so? If there were combat robots, I could retire now, so why should I rush to the front line?"

My son's guess was quite unexpected to Old Li.

"What kind of black technology is that? Isn't it just a poacher, there are basically few others, right?"

Li Bai guessed that the old man had been in charge of returning to Ma County for many years, and he had done many ruthless moves.

Use heavy punishments in troubled times, and lead to peace by harsh hands.

Those who dare to take risks are all soft but not hard. They should not be as rampant as before, and they will be seeking death if they do it again.

"We have launched four new drones, taking turns to patrol the air three hours a day, and the surveillance range can basically cover the entire area. This thing is much more troublesome!"

Old Li happily leaked the news to his son. This thing is so easy to use and so convenient, just like playing a game.

After taking off, the drone wandered around the sky for hundreds of kilometers per hour. The synthetic aperture radar and infrared thermal imaging system refreshed the ground situation like sweeping a map. None of the animals, humans and vehicles could escape.

It turned out that at least three groups of people took seven or eight days to patrol all the places thickly.

The efficiency before and after is simply incomparable.

Once the drone locks in the target, it directly sends a team to the destination for arrest. There is no need to open a large network and use manpower to search like before. Not only does it take time and effort, but people eat horses, depreciate and consume fuel, and spending is high. For the already stretched finance, it is like adding insult to injury. More budgets have to be applied for every year, and a large group of public security personnel with a serious number of exceeding the staff can maintain the local situation.

Although the four drones are very expensive and require special training to be operated, the costs before and after they are put into use are relatively relatively high. The current patrol expenditure is only one-twentieth of the previous one, and there is room for further compression, so the manpower demand is directly reduced by half.

For the finance department of Huima County, it is simply a general reduction of sweet rain, greatly alleviating the financial pressure in all aspects.

After all, the annual security budget has always been a considerable burden.

"It's just four or five propellers, the kind that can take photos in the air? It seems to be just a few thousand yuan per plane."

The drone that Li Bai remembers is the small multi-axis drone used for taking photos and videos. It cannot fly very high, but it can be used to shoot pictures that are not expensive, convenient and practical than helicopters.

But if it is used for public security and patrol, especially in places like Huima County, it can be used, but the battery life is not necessarily enough, right?

In his opinion, such a drone is only enough to monitor the county town, and it is not enough to fly far away.

Old Li shook his head and said with a smile: "The kind you are talking about is toys. I use professional goods there. One is worth 600,000 yuan, and can fly to a height of 6,000 meters, with a flight radius of 200 kilometers. It is controlled through the ground signal station and 4G network, with radar and high-definition cameras, and is almost a paramilitary drone."

Multiplying the flight radius by 2 is the maximum range, but the biggest problem in limiting the flight distance of a drone is communication means. The wireless signal power of the remote control is always limited, and long-distance control must be achieved through other channels.

The US empress is proud and can directly use satellites and early warning aircraft to maintain communication, but this is limited to the military. If it is replaced by local police departments, except for the number of guns, there is no way to find a place that can be better than China.

However, Huaxia Infrastructure is invincible and realizes remote control through the ubiquitous mobile phone signal network.

Although the Gobi Desert outside Huima County is an unmanned area, the mobile phone signal is good and there is no signal blind spot at all. The number of users is at most two or three kittens, which can easily fill the network speed peak, and it is appropriate to use the drone as a signal relay.

As for the fee, just pay a traffic fee. How much does it cost to cover unlimited traffic per month?

It turned out that what he thought was completely different from what the old man said. Li Bai asked curiously: "Can you bring a bomb?"

If you can bring a bomb, once a criminal is found, you will throw it down directly and the human body will bloom.

This is a one-time and all-out solution. Just send someone to collect the body.

Director Li deliberately lowered his voice and said, "Cough, yes! In theory, it's OK!"

If it weren't for his own little boy, he wouldn't have revealed such a secret.

The carrying weight of the drone that takes off on the runway is actually not small. The 2 kilograms of lower wings are completely stress-free. The high-energy blasting force overturns a truck is like playing. The control program also presets related modules in advance, when to use it, when to enter the permission password to unlock the function.

"This is not a black technology, it is a big killer."

Li Bai immediately understood.

Fortunately, the communication base station is used as the relay of remote control signals. If remote control is carried out through satellites, the range of hundreds of kilometers is completely different from that of a cruise missile.

So now there is no problem with the technical aspects of drones, but the safety management and control are relatively strict.

No wonder the old man said it was a paramilitary-grade drone, and he was not allowed to buy it if he had money if he had it.

That is, the public security department will approve it by itself, supervise it, manage it for its own use, and there will be no problem as a police equipment.

Huima County has even real military equipment such as tanks, and is naturally a matter of course to be equipped with drones with certain ground attack capabilities.

"Hahaha, that's...of course!"

Director Li smiled proudly.

Of course, under his leadership, Huima County Public Security Bureau kept pace with the times, adopted new technologies, new equipment, new ideas and tactics, armed with armed protection of the lives and property of the people of the county, and fought against illegal and evil forces to the end.

Drones are always fun!

After laughing twice, Old Li said, "Xiaobai, how many days do you keep during the Chinese New Year."

Li Bai replied in confusion: "The country has seven days of legal status, Dad, do you have many?"

The old man also eats the country, so he should be very clear.

"You take the time to accompany me to a place, I want to buy something!" Old Li patted the tool box of Da Ben and continued, "Just use this car!"

He knew that his son had a broken Santana 2000.

It’s unlucky for the New Year, after driving Mercedes-Benz and Santana, which is unlucky!

"I have bought all the New Year's goods!"
Chapter completed!
