Director Liang just wanted to give it a try and asked Dai Li if there was any solution.
He didn't expect that Dai Li only asked some specific questions and agreed on the spot.
Dai Li agreed so readily that Director Liang didn't even have time to react.
He was also worried that Dai Li would find it troublesome and be unwilling to get involved in such a thankless task, and he also wanted to promise that she would not help in vain, that she would receive the subsidy, and that she would not be left out of the honor when it came to rewarding her for her merits.
But she didn't even raise these mundane questions.
And when she nodded, it not only meant that she was willing to help, but also that she was able to help. She had already come up with the corresponding countermeasures when she agreed.
Director Liang was filled with emotion for a moment, and said "OK" several times in ecstasy. After hanging up the phone, he went to arrange the docking work without stopping.
Dai Li must go with them, so all matters in the company, big or small, will be entrusted to Wu Xuelin and Sister Tu.
Before leaving, she gathered all the employees and gave them instructions.
Her company now has dozens of people, and everyone regards her as the backbone. Everyone feels at ease when she is around. Now she is going on a long trip, and to such a far and dangerous place, and everyone in the company is worried.
"Daidai, do you have to go in person? The border of that place is very dangerous. Can't we just provide support from the rear?" Sister Tu was so worried that her face turned bitter.
Dai Li: "The local conditions are too complicated, and the criminals are very cunning. The situation of arresting them can change at any time. If I don't go, I will be out of reach if something unexpected happens."
Sister Tu: “But…”
Dai Li: "Director Liang is going, so what danger can I face if I follow him?"
Sister Tu pouted, and although she didn't object out loud, she was still unhappy in her heart.
Most of the employees in the company didn't want her to leave, but the boss had decided to let her go, and since it was a collaborative project with the police, they had no right to dissuade her.
The matter is settled.
Amidst everyone's instructions, Wu Xuelin suddenly spoke.
"Boss, I'll go with you." His tone didn't sound like he was asking for advice, but more like he was reporting the decision he had made.
Dai Li looked over in surprise.
Speaking of the entire company, apart from her, the most indispensable person is Wu Xuelin.
She brought Wu Xuelin up personally, and she could leave with peace of mind because Wu Xuelin was in charge.
He knows the technical work best and can solve any technical problems. Operations and management have always been his strong points. There is no need to worry about handing the company over to him.
But now, he said he wanted to go too.
Before Dai Li could express her opinion, she heard Wu Xuelin say confidently, "If anything happens to you, where will I find a boss as generous as you? I'll be left with nothing."
He was right to say that. He received a bonus in the middle of the year, which was already higher than his annual salary. At the end of the year, the bonus would only be higher than in the middle of the year, not lower.
Sister Tu: "Pfft, pfft, pfft, you're such a bad mouth, who would dare to say anything bad about you?"
Wu Xuelin: "Boss Tu is good at saying auspicious words. Doesn't saying auspicious words mean you won't worry about the boss anymore?"
"Tsk." Sister Tu was speechless.
Wu Xuelin: "And if I go, not only can I prevent the boss from getting into danger, I can also help him carry his luggage and run errands."
Sister Tu thought about it carefully and felt that what he said seemed to make sense. Dai Li just needed a laborer to do the work.
"Daidai, why don't you take him with you? You'll definitely need to bring a lot of stuff, so let him carry it all for you."
Wu Xuelin: "Whether you agree or not, I will go with you."
Anyway, he has made up his mind, it's just a matter of doing it openly or secretly.
Dai Li didn't know why he insisted on following her, but he seemed to have made up his mind, so Dai Li followed him.
"You can go if you want."
However, there are still benefits to bringing Wu Xuelin along, such as helping with luggage and equipment.
She brought a lot of things with her, three large 33-inch suitcases. Her daily necessities only took up a small part, and the rest were equipment, which almost filled up half of her belongings.
Although Director Liang arranged for someone to pick her up, having an assistant she was familiar with to help her could still save her a lot of trouble.
Dai Li, Wu Xuelin and Director Liang took a special plane to the southern border, while Qu Yan and Han Yu had already made preliminary arrangements in advance.
Qu Yan and Peng Kun have been enemies for many years. Half a year ago, Peng Kun set up a trap for him. Qu Yan said that he would personally arrest Peng Kun and send him to face the law.
Han Yu has been hanging around the borders of the three countries for many years and understands the complex situation on the borders. He also knows the general personnel structure of the Pengkun Group, who are his confidants, and what kind of relationship networks these people have. As long as he finds a breakthrough, he can follow the clues and sooner or later wipe out the Pengkun Group.
After arriving at the border town, Qu Yan immediately joined the special task force to analyze Peng Kun's movements and the fragmentary information collected.
Han Yu used his previous connections to go out and inquire about news and collect and organize information.
When Dai Li and others arrived, the special task force had not made much progress.
Peng Kun and his trusted subordinates have gone into hiding and have not been seen for more than a month. They have not gone out to buy food, used the Internet, or contacted anyone from the outside world.
Peng Kun had a subordinate who was very lustful and had five or six mistresses. He used to visit his mistresses every week and stay with them for at least one night each time.
Plainclothes officers from the special task force waited at the doorsteps of his mistresses' homes for more than a month. During this period, he did not show up once. His mistresses thought he had died outside and had started looking for other lovers.
Peng Kun is very cunning. He must have known that the number of people trying to capture him has increased, and a tight net has been laid outside. Now he is hiding more cautiously than before, and there is no trace of him, making it more difficult to catch him.
The pursuit operation has reached a stalemate, and the task force's office is shrouded in gloom.
The police officer in charge of the case couldn't help but curse.
"That son of a bitch Peng Kun, I don't believe he can live his whole life without food or water like a turtle. He's not the kind of person who can stick to his job. I want to see how long he can stay a turtle. If he has the guts, he can hide in the primeval forest forever."
"Perhaps Pengkun can really hide forever. He knows that being a coward is better than being a headless turtle."
"Impossible. He's been hiding it for over half a year. If he doesn't sell the goods, not only his people will be anxious, but his buyers will be anxious too."
"Peng Kun can't just quit. He has so many people working for him and they need to make a living. If he dares to quit, the first thing that will happen is infighting."
"So we can only passively wait for Peng Kun to show up? If he continues to be a coward, we will continue to be unable to do anything to him?"
Some police officers were fed up with this passive state, and their desire to capture Peng Kun became stronger day by day, especially after seeing Qu Yan coming.
They had known Qu Yan for many years and were teammates who had worked side by side with him. After seeing what Qu Yan had suffered, they all wanted to skin Peng Kun alive with their own hands.
If we continue to wait like this, how can we justify the suffering Qu Yan has endured?
"Captain Qu has been here for such a long time, and our work hasn't made any progress. I really don't have the face to see Captain Qu."
The bureau needs such passionate people, but what is needed more at this time is to solve problems rather than create problems.
The leader of the special task force said: "Then tell me, do you have any better ideas? As long as what you say is feasible, we will listen to you."
The man immediately deflated.
He was just complaining because things weren't going well. If he had a way, he would have brought Peng Kun to justice long ago.
Amidst the low pressure of the task force, Qu Yan walked in cheerfully.
He stood at the door and called the task force leader: "Captain Xu, Director Liang and Teacher Dai are here."
Captain Xu finally got over his bad mood, straightened his uniform, and went up to shake hands with Director Liang.
"You've made Director Liang take the trouble to make this trip. It must have been a tiring journey."
Director Liang extended his hand and shook it back. "We're all here for work. If I had to say, you guys on the front lines are working harder than me."
Captain Xu's face looked like he hadn't had a rest for a long time. His complexion was sallow and he had big dark circles under his eyes.
As soon as the report of Qu Yan's case came out, the whole country was in an uproar and it was on the front page of hot searches for three consecutive days. The cruel methods of Pengkun Group aroused the anger of people across the country.
Half a year later, people are still paying attention to Qu Yan's case and waiting for Peng Kun and his group to be arrested.
The higher-ups also issued a death order, requiring Peng Kun and others to be brought back to the country for trial at any cost.
Regardless of public opinion or orders from above, they must catch Peng Kun as soon as possible.
Not only has the task force not been sleeping well recently, they haven't had a good night's sleep in the past six months.
They were busy almost every moment, investigating, visiting, analyzing information, and formulating arrest plans. They tried their best but still couldn't catch up with Peng Kun's escape speed.
There has been no progress for more than half a year. They can't explain to their superiors, let alone the public. How can they sleep well?
While they were chatting, Captain Xu couldn't help yawning.
He quickly covered his mouth and apologized to Director Liang: "I'm sorry to have made you laugh."
Director Liang: "Captain Xu, you should make sure to rest. Your health is the capital of the revolution."
"I've rested, I just have a craving for a cigarette," Captain Xu explained, and then couldn't help but take another one. "I'll go out for a cigarette later, and I'll be fine."
The rest of the special task force is in basically the same situation.
Director Liang frowned and said, "You can't do this. Let's have the meeting first. After the meeting, everyone go back to sleep. We can continue working tomorrow morning after a good night's sleep."
The task force said nothing and just looked at Captain Xu.
Captain Xu: "Director Liang, it's only three o'clock now. How can you go back to rest? It's too early. We can still check for clues about Peng Kun later."
Director Liang: "Do you have any clues about your current investigation?"
Captain Xu: "We are in a meeting to sort it out."
Director Liang: "Do you have any new clues about Peng Kun?"
Captain Xu scratched his head and said with a hint of resignation, "Nothing has happened in the past month. Peng Kun has become more and more cunning and has hidden his tail very well. Not only has he not shown up, but the people in his gang have not shown up for a long time, as if they have evaporated from the face of the earth."
Director Liang: "Since you don't have any ideas for now, why don't you listen to our ideas first."
Captain Xu's eyes lit up: "Does Director Liang have any good ideas?"
Director Liang didn't say anything. He turned around and asked Dai Li: "Teacher Dai, you should speak."
"Teacher Dai?" Captain Xu then noticed Dai Li behind Director Liang.
Qu Yan: "I forgot to introduce this to Captain Xu. This is Teacher Dai, the expert who is here to assist us in apprehending the Peng Kun gang."
Captain Xu looked at Dai Li in astonishment and with an inquiring look, because she really didn't look like an expert at all.
Director Liang: "Don't underestimate Teacher Dai because she's young. She's very capable. There's almost nothing she can't do."
Qu Yan: "Han Yu and I were both cured by Teacher Dai. If it weren't for Teacher Dai's help, Han Yu and I would still be half dead, living like neither human nor ghost."
Captain Xu had heard about Qu Yanhao and Han Yu's situation, and he immediately respected Dai Li.
"Teacher Dai, nice to meet you. Thank you for your guidance in the future."
Dai Li shook hands with him and said, "Captain Xu, you're too polite."
Captain Xu asked Dai Li and Director Liang: "Should Teacher Dai speak first or Director Liang?"
Director Liang waved his hand and said, "I can't explain Teacher Dai's professional knowledge clearly. Let Teacher Dai explain it herself."
He and Qu Yan both found an empty seat and sat down.
The members of the task force also sat upright, opened their notebooks, and prepared to record the key points of Dai Li's explanation.
Generally speaking, all the experts invited to the task force have some real skills, and their insights are very unique and their ideas are very sharp. They can often find new breakthroughs in their own way.
Their arrest efforts have stalled, and they really need an expert to help them open up their minds and find new breakthroughs.
The members of the task force looked at Dai Li with great anticipation as she came to the screen, thinking that she had prepared a large amount of PPT materials and was going to analyze the case to them.
As a result, she didn't prepare any PTT and started speaking directly.
"I heard from Director Liang that the criminal is hiding in the primitive jungle and has been hiding from place to place and hasn't shown up. The task force has no way of determining his exact location?"
Captain Xu explained, "He's hiding in a place called the no-man's land, a place where three countries meet. We don't know which country he's in. The terrain is complex, and the locals can't tell the way around. They rarely venture into the forest. It's deserted and there's no signal. If someone hides there, it's like hiding a needle in the ocean. Unless he reveals himself, outsiders won't be able to find him."
Dai Li nodded thoughtfully, then smiled.
"Although he can hide his tracks, there is one thing he can never hide, and it will always reveal his location."
"What is it?" Captain Xu asked anxiously.
Dai Li: "Smell."
Captain Xu was puzzled: "What's that smell?"
"The smell of a person." Dai Li said.
"Each of us has our own unique scent. No two people in the world have the same scent. Just like fingerprints and irises, it is our personal label that will accompany us throughout our lives. So we can find Peng Kun by scent. For example, your police dogs can also use scent to catch people and search for contraband."
The task force members thought she was dreaming: "The no-man's-land area is over 200,000 square kilometers. How many police dogs would we need? How long would it take to search it all? Besides, there's so much rain in the jungle that scent trails would be quickly washed away."
Captain Xu also shook his head. "It's really unrealistic. Not to mention the manpower and resources it would take to cover over 200,000 square kilometers, the police dogs wouldn't be able to handle it. Police dogs have a keen sense of smell, but they're not suited to long-term, long-distance pursuits and are easily affected by the environment."
The members of the task force shook their heads and raised their own questions.
However, Qu Yan and Director Liang were both listening calmly, and seemed to approve of her plan and did not think it was unreliable at all.
Dai Li: "Of course we can't use police dogs. We need a tool that is more efficient and less prone to errors than police dogs to complete their work."
Apart from police dogs, Captain Xu couldn't think of any other animals that could replace police dogs in a way that was both efficient and less prone to making mistakes.
Dai Li: "Of course there is. I call this thing an odor molecule sensor. I use a collector to collect the smell of Peng Kun's personal belongings. Through data analysis, I can get his body odor data. Then I use drones to search the airspace above the border of the three countries. As long as Peng Kun appears within a ten-kilometer range, his body odor can be accurately detected."
The task force members were stunned.
They understood every word, but it was not easy to make them comprehend.
What is an odor molecule sensor? What does it mean to analyze body odor data? How can we achieve a search within a ten-kilometer range?
Smells can be collected, analyzed, and searched? I've never heard of this before.
All members of the task force were confused by her words.
Captain Xu: "Teacher Dai, are you kidding us?"
Dai Li did not directly answer Captain Xu's question, but asked the members of the task force.
"Has anyone heard of the XIU phone before, or has anyone used it? The one that can smell."
The members of the task force present here work in a small border town all year round, so they don’t have the time to go to a big city to buy a mobile phone. Besides, the price of 9998 is not something that ordinary people can afford. However, they have heard of the reputation of the “XIU” mobile phone.
"I've heard of it but never seen it. It's been really popular online lately."
"I haven't seen anyone around me use it. Can you really smell it?"
"I've seen it. Last time, a group of young people from a big city came here for tourism and got into a conflict with another group. I was the police officer who responded. Several of the young people in that group were using XIU phones. After the case was closed, I borrowed one to take a look, and it really can smell. It's pretty amazing."
"Last time, my friend went to buy one and asked if I wanted him to bring one for me. I couldn't bear to part with the money and was even more worried it was a gimmick. Last time I went to visit him on vacation, I got to play with his phone and it was truly eye-opening. I really regret not asking him to bring one for me. Now it's even harder to buy one; you can't even get one."
When it comes to new things, everyone seems to have endless topics to talk about.
What Dai Li said next was so casual that it made them all speechless.
"The XIU phone is made by me and manufactured by my company. It emits scents because it has an odor molecule sensor inside it that can collect, analyze, and process various odors."
The reaction of the task force members was nothing short of petrified.
They thought the person who came was a hunting expert, but they didn't know that he was not only an expert, but also a big boss.
Team Leader Xu: "Teacher Dai, are you saying you've developed an odor molecule sensor that can make phones emit scents and can also search for suspects?"
Dai Li felt that no matter how much she talked, it would be better to let everyone see the actual effect.
"How about we all see the effect of the odor molecule sensor first?"
Captain Xu asked bewilderedly, "Teacher Dai, what are we going to do about this?"
"Of course, we should catch the one you haven't caught first." Dai Li stretched out her hand to the side, and Wu Xuelin handed a piece of thin paper to Dai Li.
Dai Li shook open the thin paper, revealing the face of a middle-aged man.
"For example, the person on this wanted poster."
This border town is a mixed crowd with winding and complex terrain. Countless people travel back and forth between the country and abroad every day. People who have committed crimes will smuggle out of the country from here to avoid the spotlight, and people from abroad will also smuggle into the country. There are many unstable factors.
The man on the wanted list has committed many crimes.
In the early years, he stole to get money for drugs and massacred the entire family of five for just 500 yuan. Many years have passed, and it is still a major unresolved tragedy in the city.
Later, he changed his name and went to another city, where he murdered a female college student. Because she had too little money on her, he tortured her body beyond recognition and flushed her lower body organs into the sewer.
Although the police collected his DNA, it was still very difficult to catch him.
He has a very strong anti-detection awareness. After committing a crime, he would change his name, spend money to get a fake identity, and move to a new place.
After gaining the ability to see everywhere, he often wandered around remote towns, hiding there for several years.
He would not go to a big hospital for treatment, did not use a bank card, had no contact information, and would not use any documents that would reveal his identity.
During this period, he continued to commit crimes. When he had no money, he would steal or rob. His methods were extremely brutal and there was no pattern to his crimes. He often committed crimes on a whim and would immediately move to another location.
If we can't arrest him before he escapes from the crime scene, who knows how many victims he will have when he shows up next time.
The reason why Dai Li saw his wanted warrant and saw martial law and checkpoints everywhere was because he committed another crime here yesterday.
He broke into a house to steal and had evil intentions towards a sleeping girl. When he was about to commit the crime, the German Shepherd raised by the girl was awakened, got up and bit his vital parts, holding on tightly and refusing to let go.
His screams of pain, like a pig being slaughtered, woke the girl up.
However, the girl was not a pushover. She took out an electric baton from under her pillow and started beating the suspect while calling the police.
Seeing that the situation was not good, the suspect kicked the German Shepherd hard, knocking the dog to the ground.
With a "crash", the dog tore a hole in the crotch of his pants.
The dog fell to the ground and screamed in pain, waking up the nearby residents, and the surrounding neighbors started turning on the lights.
The criminal suspect didn't bother to settle the score with the girl and the dog. He covered his crotch-less pants and ran out for his life.
When Dai Li and the others followed Captain Xu to the girl's house, the girl was caressing her dog's fur with great concern.
Yesterday, after her dog was kicked hard, it lay on the ground motionless, refusing to eat dog food or drink water, and even refused to play with its favorite little yellow duck toy.
When the girl woke up in the morning, she took the dog to the pet hospital. After an X-ray, she found that one of the dog's ribs was broken, but fortunately the dog's internal organs were not injured.
After getting treatment at the pet hospital, she took the dog home.
Seeing Captain Xu coming, she still feels a lingering fear: "If it weren't for Didi, I might not be here now."
Captain Xu: "Is your Didi okay? Has he been to the hospital for a checkup?"
"One of my ribs was broken. He kicked me so hard. If he had kicked me, I would definitely not be as strong as Didi. It woke up the neighbors and then fell silent. It didn't bark again all night. It kept lying on the head of my bed to watch over me, worried that I would be in danger again." The girl burst into tears at the end of her speech, and the dog licked her hand gently beside her.
The accompanying policewoman put her arm around the girl's shoulders and comforted her: "Don't be afraid, we will catch him soon."
"Really? Don't let him get away again. He didn't harm me this time, but if you let him get away again, he'll definitely harm others. Others might not be as lucky as me."
Captain Xu: "Don't worry, we will definitely catch him this time."
The girl wiped her tears and nodded heavily: "Yes, I believe you."
Captain Xu: "I remember Didi bit off Gou Liqiang's crotch yesterday."
The girl remembered Gou Liqiang's embarrassed look when he was escaping, and patted the dog's head proudly.
"Of course I did. He almost bit off my flesh."
Captain Xu: "Is the cloth from his pants still at your house?"
"I think so. I have to look for it. There were so many people coming to my house last night. I don't know where they were kicked off to."
The girl was about to stand up to look for it, but Didi jumped down from the sofa first and picked up a piece of black cloth from behind the curtain.
From the appearance, it is the cloth on Gou Liqiang's pants.
Captain Xu put on gloves, put the cloth into the evidence bag and handed it to Dai Li.
"Teacher Dai, try this first."
Just as Dai Li was about to take it, Wu Xuelin stretched out his hand to block it.
"Let me do it."
He put it on his hand and, with a look of disgust on his face, pinched the fabric of Gou Liqiang's pants with two fingers.
Although Wu Xuelin was disgusted, she still carefully collected the smell information from Gou Liqiang's pants.
Not only were Captain Xu's men watching curiously, but the girl holding the dog's head was also curiously inquiring, wondering what they were doing.
About a minute later, Dai Li's data analysis came out with the results.
Dai Li: "He's not far away, at a hotel 7 kilometers from here."
