National Forensic Doctor

Buzz…

A line of drones lined up and returned from the mountain stream. They continued to absorb the returning drones along the way. They hovered in mid-air until they reached the open space in front of the mountain pass, and then slowly landed one after another.

At the same time, the fully charged drone takes off when it's time to take off and ejects when it's time to eject.

The commander responsible for the operation of these small drones checked the returning drones with his subordinates. After confirming that they were correct, he ran to the command vehicle in front of him and shouted "report", and then said: "The target area has been searched. , nothing found.”

"Continue the search." The captain in the command car responded, then turned to Jiang Yuan and Xu Taining and said: "In this case, D3's search will be completed."

"Then please ask the troops to move forward and continue searching." Xu Taining was in a stable mood.

"Yes." After confirming with his superiors, the captain began to issue orders.

The lieutenant colonel next to him coughed twice and said: "Xu Chu, do you really not want to consider searching the mountain pass first? Based on our experience, after entering the mountain, the roads that people can travel are actually limited. Liang Ming Mountain here, I I have been here three times. The trails in the mountain basically follow the mountain pass. Only when you reach the main peak do you climb the ridge. Moreover, climbing the ridge is the easiest way to be discovered by drones..."

Xu Taining smiled and said: "Searching the mountain pass first is indeed a plan. It should be said that it is a relatively efficient plan. But out of caution, I think it is better to proceed step by step. I am mainly worried about two issues. The first one is When we go along the mountain pass, it is easy for the troops to become thin and easy for prisoners to escape. Secondly, we must prevent prisoners from hiding in caves or deep mountains and old forests. "

The lieutenant colonel detachment leader frowned and said, "You're thinking too much. This level of infiltration and the ability to survive in the wild, not to mention criminals like this, even the special forces in the army may not be able to complete it. It's only possible if you are at the level of a military king. Don't look at how many heroes in the history of war have accomplished this feat easily, but they were all done by dead men."

Xu Taining also became a little more serious: "The problem is that if these two people run out, or even just one of them runs out, they may kill many people. At that time, what use will the energy we save? "

The lieutenant colonel detachment leader was stunned.

Xu Taining smiled, softened his tone, and said: "Lieutenant Colonel Zhang, we think about the problem from different angles. You may be thinking about how to complete the task as quickly and cost-effectively as possible. In most cases, you also need to consider the issue of cost-effectiveness. In our words... At least, that's not the calculation here. In fact, think about it, the number of drones you command, and the large drones flying in the sky, just to catch two people, what's in it? Value for money.”

The command vehicle in charge of Lieutenant Colonel Zhang also controlled several large drones, which were flying over Liangming Mountain at this time. These big guys with a wingspan of more than 10 meters need a special take-off and landing site, so they do not take off and land here. However, the amount of information collected is huge, and the efficiency is not available in small drones.

Lieutenant Colonel Zhang smiled bitterly after hearing this: "It seems that I have overthought it. I originally thought that I could at least catch the person faster, so that it would be easier for you to explain."

"It would be nice if we could hurry up. But let's say privately, it's none of my business if the leader is anxious." Xu Taining smiled and said: "As a leader, you deserve to bear the pressure. If you can't bear the pressure, what kind of leader do you do? Isn’t it right? It’s easier for me to do it quickly, but doing it quickly is nothing more than making the leader happy. But what’s the point of being happy if the leader is happy? If you’re happy earlier, you’ll be happier later. Maybe you’ll be happier if you’re happy two days later. But at what cost?"

Lieutenant Colonel Zhang was speechless. What could he say if someone could control his leadership?

Xu Taining said happily and said to himself: "I haven't seen many things like fast and good. If the superiors want to drive to 120 despite the speed limit, the middle-level people have to increase the speed to 144, and at the execution level they have to Drive to 180, why? Because you will always encounter congested roads and slow down to avoid it. If the superior wants to drive at 120, the speed must be 180. Isn't that dangerous? "

"You criminal policemen are so scheming." Lieutenant Colonel Zhang seemed to praise him but not praise him.

Xu Taining also smiled. He had been working for so many years, and he had not received many flowers and complaints, but there were still many people who came to him to handle cases. Xu Taining was not prepared to change it.

In a job like his, being nice is not only useless but harmful. In fact, all criminal police officers are similar, especially old criminal police officers. They look at people differently. After doing many serious cases, they often look at their family members with probing eyes, which is probably unpopular.

"Let's eat." Xu Taining smiled and said, "We can push forward after lunch. As long as people are in the mountains, we won't be afraid."

"The game in the mountains is unlucky." Lieutenant Colonel Zhang also laughed.

"You said they were game. Besides, they only hunted a few game." Xu Taining blinked.

Lunch is cooked in the army's Type 97A field cooking truck. Four soldiers in the cooking class can cook a ration of meals for 150 people in an hour. The teams surrounding the mountain are based on squadrons (companies) and eat one hour apart. A cooking truck can solve the supply problem of a brigade (battalion).

And to encircle Liang Mingshan - although it is not a real encirclement in the physical sense, it is not something that a detachment of more than 1,000 people can handle. Taking into account the need for defense changes, more than a dozen cooking carts are needed for cooking.

During the mission, the food standard is naturally as high-profile as possible, and meat is especially provided.

Not too much or too much. They are all young men around 20 years old. After climbing a mountain for a day, no matter whether they are running back to eat or delivering food, everyone has a huge appetite, and 97A can only steam 25 kilograms of rice at a time, even if it is added. When serving steamed buns or steamed buns, you need to add a lot of protein.

The appetite of middle-aged and elderly men such as Xu Taining and Liu Jinghui has obviously decreased. Three taels of rice per person is more than enough. They only dare to eat the same type of braised pork and steamed pork to avoid buckling their belts.

Jiang Yuan took a lunch box of rice, poured a lot of braised beef with potatoes, and mixed a little crispy pork into it. He ate it all with a slurp. Then he packed a box of rice, first poured the braised pork soup, and then Add tomatoes and scrambled eggs, then cover it with half of the steamed pork, half of the sliver meat, and finally a little green vegetables. It doesn't matter what the name is, just stir-fry with minced garlic.

"Huh..." Jiang Yuan took a long breath after finishing the second box of rice, then opened a can of Coke and took a big sip, feeling that his whole body was full of energy.

"I envy you young people." Xu Taining also let out a long sigh. He mainly ate vegetables, which tasted very average. The young people in the cooking class obviously lacked enthusiasm for this kind of food.

Jiang Yuan cannot empathize with Xu Taining, just like ordinary people in Jiangcun cannot empathize with ordinary people in Ningtai.

Jiang Yuan wiped his mouth and said: "Young people are full and go to work."

"Thank you for your hard work. Hey, I also envy your brain." Xu Taining also coveted the many techniques Jiang Yuan had mastered. There are many forensic doctors who know about trace examination, but those who know about satellite remote sensing and can read and make pictures are very rare.

As a native of Jiangcun, Jiang Yuan was surrounded by all kinds of envy when he grew up, so he smiled naturally, waved his hands and went to look at the pictures.

Lieutenant Colonel Zhang quickly followed up, took out the specially prepared three-proof notebook and gave it to Jiang Yuan, then connected it to the data line and updated the data brought back by the drone.

Jiang Yuan first started a simple sweep with Pix4d. The amount of data brought back by drones is so huge that data processing becomes a real bottleneck.

For this reason, after weighing the pros and cons, Jiang Yuan exchanged one of the two accumulated first-class merits for Image Recognition and Analysis (LV5).

It was also because he had accumulated two first-class merits that Jiang Yuan was able to make such a decisive decision.

He was prepared that if he encountered a case that really couldn't be solved, the other first-class weapon could still be used.

"Image recognition and analysis" can not only be used in images brought by drones, but also images captured by satellite remote sensing or photos.

For a modern society with countless cameras, the application range of this skill is wide enough, and it can make up for Jiang Yuan's shortcomings in skills.

The technicians of the Scouting Brigade are certainly useful, and you can have as many as you want, but expert technicians who can reach LV3 are too rare.

The asking prices outside are too high, and you have to have a strong heart or a strong family background to resist such temptations.

Jiang Yuan selected a batch of the brushed images and then processed them carefully using LV5's image enhancement technology.

Lieutenant Colonel Zhang is also a professional, so he can naturally understand Jiang Yuan's operations, so he has been waiting nearby, serving tea and water while secretly learning techniques. Mainly the former.

Compared to Xu Taining, Lieutenant Colonel Zhang admired Jiang Yuan more.

Essentially, the two people are actually doing the same thing, they are both trying to find a needle in a haystack. However, Xu Taining knew that the needle was in the sea, but Jiang Yuan did not. Just like the batch of images in front of him, there was a high probability that there was no usable information, but Jiang Yuan still had to handle it well, even more carefully.

Just because you can't find it doesn't prove it doesn't exist. Even after searching carefully, you still can't find it. It still doesn't prove it doesn't exist. You can only keep searching, be full of hope, and be more serious...

Lieutenant Colonel Zhang knew that he did not have Jiang Yuan's skills, but what he was even more uncertain about was that if he had Jiang Yuan's skills, would he still be so serious about looking for hope?

"Lieutenant Colonel Zhang?" Jiang Yuan took a sip of coffee.

"Here!" Lieutenant Colonel Zhang stood at attention subconsciously as if he was called by his superiors.

Jiang Yuan was stunned for a moment, then smiled and said: "There are several routes here. Please arrange for the drone to fly again. You can fly lower and take better pictures."

Jiang Yuan picked up the paper map and drew a big sausage ring on it with a pencil without using a ruler.

"Yes. Do you need to send a squadron to conduct an armed reconnaissance?" Lieutenant Colonel Zhang was worried that Jiang Yuan was reluctant to use troops.

"No need for now." Jiang Yuan slowly shook his head and said, "Because this area is a broad-leaved mixed forest, it is difficult to identify the images captured by the drone."

Lieutenant Colonel Zhang hesitated for a moment and said: "If it flies low, the prisoner will hide when he sees the drone... Or, I will send another high-resolution large aircraft over..."

"No. I want to scan this area, not to see where the prisoners are, but to see if there are any traces left by them."

"Can you see the traces?"

Jiang Yuan looked at him strangely and said: "As long as the resolution is sufficient, identifying images is nothing more than a matter of feature extraction... Of course, identifying traces left by living people is more difficult than identifying obvious targets such as dead people, but this The two fugitives are not very professional and have left heavy traces of their lives, so there is still hope. "
