The next day.

Tang Rui drove away from home to buy materials for firefighting drones.

The prices of various materials and the models of accessories, he had already checked yesterday.

Just go straight to your door and buy it today.

Let's be honest.

He is still more conscientious.

For the body of the firefighting drone, he did not use the cheapest materials, but used 6051-T6 grade aluminum alloy.

This kind of aluminum alloy is almost 20 yuan a kilogram.

Of course, it costs a little more money here, and it will definitely have to be made up from somewhere else.

So he replaced the turboprop engine that was originally going to be used.

Switch to a propeller engine with a brushless motor.

Originally, he wanted to buy the 18 yuan kind, but then he found that he didn't have enough power and couldn't afford it.

In the end, he picked for a long time and chose a 150 yuan waterproof version of the brushless motor of the external rotor.

This is already a lot of money, and it is the second most expensive accessory for firefighting drones.

As for the first expensive accessory, of course, it is the optoelectronic system.

Other places can save money as much as possible, but the optoelectronic system can't, otherwise flying out will be a toy.

The whole optoelectronic system costs 780 yuan, of which the lens costs 220 yuan, but it can't be bought without it.

Plus steering motors, flight control motherboards, processors and a series of other accessories.

The cost price of the whole firefighting drone reached 1282.5 yuan.

It doesn't look expensive.

But when the quantity is large, it is not cheap.

According to his ideas.

This kind of firefighting drone must be hundreds of them taking off together.

Otherwise, a dozen of them alone will have no effect at all.

So, the first time he bought materials, he bought materials for 64 drones. A total of 82,080 yuan was spent.

Hemorrhage.

The money in his grandmother's bank card was directly used by him.

In addition to buying materials, he also rented a small cottage with a yard.

No way.

There are so many things that I can't put in my home.

Drones can't be moved right now.

Not to mention that he has to do something else in the future.

This kind of small cottage with a yard is the most suitable for him.

In fact, when it comes to this small villa, he hates itchy.

He remembered that the villa in this area was only sold at a price of 4288/㎡.

I haven't sold much for half a year.

At that time, his father wanted to buy it, and he was optimistic about the house.

As a result, there was a quarrel, his parents divorced, and his big villa was yellow.

Even if you get a divorce after buying the villa.

It's all tears.

Thinking about this, he was upset, so he decided to call his grandmother in the evening, saying that his father hadn't contacted him for a month.

Tossed all morning.

It cost a hundred thousand.

The money was spent, which made Tang Rui tremble a little.

After all, it's a habit of thrift.

It's a bit unbearable to spend so much money at once.

The beef noodles at noon are not fragrant in your mouth.

"Xiaoyi, do you see if Huawei's verification of the algorithm has any results?"

During lunch, Tang Rui thought of money and thought of Huawei.

It's been a day.

There is no news from Huawei's side yet.

There is no money coming in, so he has no bottom in his heart.

"Master, do you want to investigate the relevant information of Huawei's algorithm?"

"It's not the information of Huawei's algorithm, it's the image algorithm that was passed to Huawei yesterday, has Huawei verified it?"

"Xiaoyi doesn't understand."

Gan!

Although it is artificial intelligence, the fuzzy recognition ability is still not enough.

"Bring up the directory of reports submitted by Huawei from last night to today."

"Okay, master, I'm collecting and sorting out the information."

I finally got it.

Swish!

A long list of reports appeared before his eyes.

"Find keywords, image algorithms, and block other irrelevant information."

"Done."

There are only seven reports left, one of which is a summary report on image algorithms.

Tang Rui opened it and took a look.

After updating the image algorithm, the effect of taking photos without replacing the hardware device is increased by 1.6 times on average.

In particular, the optimization of long-distance shooting has reached a staggering three times.

However, in the end, the technical department also made it clear that this image algorithm is not complete.

There should also be a lack of image recognition and image analysis algorithms.

After reading this report, Tang Rui wanted to give Huawei the technical department a thumbs up.

The report is right.

What he sold to Huawei was the split algorithm, and it was a beggar's version.

Don't assume that a clear photo is useful.

The clarity of the photo, that's just for people.

For the machine, the most important thing is not the shooting effect of the photo, but whether the machine can recognize the information in the photo.

Especially for driverless systems.

The machine does not recognize.

No matter how clear the photos you take, they don't work for birds.

However, he is not in a hurry to sell these algorithms.

After all, taking the initiative to sell things at your door and begging you to buy things are two different things.

It's not just a matter of initiative.

There are also some psychological gaps.

Finally, he glanced at when the report was uploaded.

Boy.

It was 3:27 a.m. this morning.

It deserves to be Huawei.

It's really good for liver.

Now that the test report has come out, Huawei's top management should be in a meeting to discuss it.

In this case, he will not be in a hurry.

After lunch.

Just as he was about to go home to build a firefighting drone, Officer Chen called.

Ask him if he has time.

If you have time, go to the police station and get the bonus.

How can you not have time to take the money.

Tang Rui immediately said that he would go over immediately.

rushed to the city bureau in a hurry.

Came to Officer Chen's office.

He knocked on the office door.

"Please come in."

Tang Rui pushed open the door and looked inside.

Boy.

Is the panda a sperm?

Why are they staring at the dark circles one by one, as if they haven't slept for half a month.

Throughout the office, there were more than a dozen policemen, and the dark circles under their eyes were getting worse than the other.

Luckily, the people in this office are all young people.

It's still up to it.

Anyone who has passed the age of 40.

It is estimated that they will have to be pulled to the rescue.

"Tang Rui is here, please wait for me a while, I'll finish watching this video, and I'll take you to finance."

Officer Chen looked at the panda eyes and said weakly.

"It's okay, you're busy, I'm not in a hurry."

Tang Rui said indifferently.

Looking at this situation, you can know that they must have something important, otherwise it would not be so liver.

So he found a random place, sat down and waited for the other party.

Still, he was curious.

What the hell is going on.

So he looked at Officer Chen's computer screen.

Video surveillance footage?

Or a video shot at a traffic light.

This is watching a video, querying what vehicle?

Tang Rui was a little confused.

After two glances, he stopped looking, it was boring.

Sitting there bored.

His eyes began to wander.

Well?

Suddenly, he saw a document.

It's still very scary information.

"Dong Jing, female, 25 years old, ID number...... Cause of death: suffocation.

Time of death: From 1 a.m. to 3 a.m. on the 4th, the corpse's face was severely damaged, and he was abused and abused before his death......"

This is the text content exposed on the data, and the rest is blocked by the photo.

And that photograph is a photograph of the deceased, taken by the forensic doctor at the place where the body was found.

None of this is critical.

The most important thing is, how can the deceased in the photo look so familiar to him?

But he knew people.

There is absolutely no such thing as Dong Jing.

Tang Rui frowned and thought for a long time, and after checking the people he knew, he began to investigate the female anchors he paid attention to.

"What do you think, let's go, go get the money."

Officer Chen walked over and patted Tang Rui on the shoulder.

"Oh...... Good. ”

Tang Rui was stunned for a moment, got up and followed him out of the office.

"Brother Chen, what's the situation, they're all about to become national treasures."

On the way to finance, Tang Rui asked curiously.

"Don't say it, I've watched the monitoring for three days, and my eyes are dazzled."

Officer Chen waved his hand, and he felt a little like vomiting when he talked about the surveillance.

"Three days? Are you looking for a wanted criminal or a criminal, and you haven't found it for three days? ”

"Don't say three days, at this pace, in another month, it's hard to say whether you can find clues."

"Can't you do facial recognition?"

"What about face recognition? Now we don't even know what a murder looks like, how to recognize it. ”

"Can you tell me? Don't break the discipline. ”

"There's nothing that can't be said, it's just that a few days ago, a woman was killed, and no suspect has been found.

The only thing that is known at the moment is that the deceased went to the bar that night, and then met a rich second generation or a rich man who I don't know.

She went fishing for Kaizi, but Kaizi didn't catch it, but instead put herself in it. ”

Fishing Kaiko!

Tang Rui suddenly remembered.

No wonder he thought the dead man looked familiar.

Balenciaga stockings.

Silver dress.

Isn't this the woman he photographed as the co-pilot who was in the co-pilot and said he wanted to fish for Kaizi last week.

Unexpectedly, that night, she was gone.

Isn't that a coincidence?

He has the clues that the police are looking for.
