The way of solving cases with investigation and visits, surveying and queuing, and sitting in the hall for interrogation is fully reflected in the "Old Marshal".

There are no more clues, so I can only check this at this stage.

Six groups became eight groups. The seventh group set up at night was responsible for arraigning or accuseing all prisoners and criminals in the three districts who were involved in explosives. The eighth group investigated all air conditioners in Nangang City engaged in the production, sales, installation, maintenance and recycling of air conditioners.

The eighth group has three exploration groups, Jin Yang and Cheng Wenming's exploration groups are one of them, responsible for investigating the jurisdiction of the Development Zone Branch.

There are no air-conditioning manufacturers in Nangang, and there will be no development zones.

There are many employees related to air conditioners. There are three large shopping malls, more than 20 stores, six special repair stations that can be found, and more electrical repair departments are registered.

The two of them were undoubtedly too busy and were not familiar with the development zone. The project command had already considered this and asked the branch to arrange four police officers to assist. There were too many lines to investigate and normal work could not be delayed. If the branch criminal police brigade could not get a job, the "old coach" would never have made such a bad move.

To solve the case within a time limit, we must race against time. The command center requires each probe team to report every two hours.

After the meeting, the six people were divided into three groups to act separately.

Lao Wu, a police officer from the Public Security Brigade, was familiar with the situation and stayed in the branch office to continue counting the list of people to be investigated. Like Jin Yang, Cheng Wenming asked a policeman from the branch office to be a guide and first look for the person he could find.

All the police officers of the branch were on duty, and the branch only kept the on-duty staff, and did not return to the unit to rest until after one o'clock in the morning.

According to the original arrangement, I could sleep until 9:30 in the morning and have a "morning lunch" to patrol the Development Avenue. Unexpectedly, I was woken up at 7 o'clock to cooperate with the person around me to investigate, install and repair the air conditioner.

Never have such New Year's Day passed like this. Xiao Wu, a policeman from the National Security Brigade of the Branch, yawned Liantian and pointed to the row of shops in front: "Captain Cheng, the door is open, there are people in this family."

"I noticed it."

Cheng Wenming parked the car to the side of the road, picked up his bag, opened the car door and walked to the door of the "Dinger Electrical Repair Department".

The door was open, but no one was in the store.

The business looks good, with seven or eight black and white TVs at the door, an old washing machine and a "Xiangxuehai" refrigerator. There is no place to put it inside, all of them are TV sets, recorders, DVD players and various circuit boards.

The workbench is an old desk placed beside the door.

A back cover on the table is opened, revealing the buttocks of the radiator tube and the dusty circuit board. Next to it is a multimeter, oscilloscope, soldering iron, screwdriver and other maintenance tools, which look very messy and professional.

"Where is the person who repairs the electrical appliances, why isn't the person not here when the door is open?" Xiao Wu looked around and asked the master who repaired the motorcycle next door.

"Just now, I might go to the vegetable market to buy vegetables. Public Security Comrade, are you okay with Ding Er?"

"It's nothing big."

I couldn't understand the local words, so Cheng Wenming looked inside again, and asked in Mandarin with a bag in his arms: "Master, will Ding Er repair the air conditioner?"

"Repair, as long as the electrical appliances are fully repaired."

There are many policemen who speak Mandarin in the Development Zone Branch. Motorcycle mechanics are not surprised. They pick up a rag to wipe their hands, and get up and said, "But air conditioners are different from TVs. They are not available in every household. Rich people buy air conditioners, which are warm in winter and cool in summer. Enjoy it! Who will buy them? Wear more clothes in winter and blow electric fans in summer. Few people buy them, and even fewer repair them. I saw him repair the window machine once and install the kind on the window."

I had the opportunity to participate in the investigation of the huge explosion, but I was arranged to investigate these things.

Cheng Wenming felt a little ridiculous, but he had to do his job well, so he asked: "Master, will he move the machine?"

"Move the machine?"

"It's just to remove the air conditioner from one place and install it in another."

"I guess this can't be done. Now there are few window machines, new air conditioners that can be used to drive holes on the wall. Some of them have to be installed on several floors. No matter how he does it alone, he doesn't have the tools."

...

After asking for a while, Xiao Wu asked a enthusiastic person to find Ding Er.

He is in his thirties, short and fat, wearing thick glasses, and lives a good life. He bought several kilograms of ribs and planned to braise them for his son at noon.

The business is very good, the reputation is good, and the family is happy. Life is very simple. I stay in the store during the day, go home to cook at noon, and go home to accompany my wife and children at night. I hardly go far away. I even rarely go to the city. I have no intersection with the Ocean Engineering Group and the Second Construction Company, and I have no criminal record.

What problems can such a person have? At most, you can get some stolen goods with a small price.

Ding Er had no problem. He ran down one morning and all the dozen people he had checked were fine. Just when he received the eighth text message and was about to touch the seventeenth person, Han Bo had finished the investigation of Xinyuan Community and returned to the technical brigade to prepare for the extraction of the lightning-guard DNA.

"Get away from the laboratory and bring the rack here."

"Jiaqi, pack up the container, be careful not to break it."

Too dangerous, what if it explodes?

Li Jiaqi's heart was pounding, and she was so nervous that she was at a loss. From the moment she heard that he wanted to extract the DNA on the Lei-Guan himself, she had the idea of ​​calling Li Xiaolei more than once.

She was nervous, and the bureau leader was also nervous. Director Cui came here in person on behalf of Director Chen.

To ensure that everything is foolproof, Director Cui sent someone to the Armed Police Detachment to bring two explosive uniforms and a large iron bucket. He should not wear thick gloves on his hands, so it is okay to wear thicker on his body. Wearing a explosive uniform and a storm helmet can at least ensure that his face and chest will not be injured. After all, compared to bombs, the explosion power of the thunder tube is much less powerful.

As for hands, you can only send an ambulance to the First People's Hospital, and two doctors and a nurse sit in the car on standby. It is best not to have any accidents. If an accident occurs, you can treat it in time.

A hero and model, do you have to miss your arms and legs?

Director Cui was still a little worried and looked up and said, "Xiao Han, come here."

"Director Cui, what instructions do you have?"

Director Cui patted his arm, turned around and looked at the police officers of the Science and Technology Department (Technology Information and Communications Department) who had just arrived, and half-jokingly said: "I asked them to install cameras and CCTV surveillance. I will watch you operate next door later. The whole process will be recorded. Be careful, if you find something wrong, throw it into the explosion-proof bucket immediately. Don't let the videotape become a hero and model deeds material."

Throw it into the explosion-proof bucket. If you are really lucky, will it be too late to explode?

But this was also the leader's kindness. Han Bo promised again: "Thank you, Director Cui for your concern, I will be careful."

"Young Marshal" is not afraid, what is the most common technical policeman afraid of!

There are not many opportunities to show off like this. Wan Peng secretly put on the second explosive suit and ran out to the attention like a cotton bag and saluted: "Report to the Korean team, please allow me to be your assistant."

Director Lan was ridiculous and without waiting for Han Bo to speak, he pointed at him and said, "Young man, this one is prepared for me."

"Damn it!" Director Cui glared at him fiercely and said coldly: "Take it off, take it off quickly. You are not a blasting expert, what can you do when you go in?"

The morale of the technical brigade is not high at all, and his subordinates are willing to go in together, how can they suppress his enthusiasm?

After taking protective measures, he was kept away and he didn't need to take action. There should be no danger. Han Bo weighed it and said with a smile: "Director Cui, don't let Wan Peng take off the explosive server. I really need an assistant. Director Lan, the bystander is clear, you will see clearly next door. We will turn on the phone hands-free, and you can guide you next door."

If Lei Guanzhen can't react at all, it's actually no difference if he can't get in.

Director Lan sighed inwardly and smiled bitterly: "Okay, I'm next door."

"Okay, you'll be an assistant." The two professionals had no objection, so Director Cui naturally had no choice but to object.

Xintong police officers were familiar with CCTV surveillance and it was done in just ten minutes.

Han Bo was wearing a thick blasting suit, opened the back door of a police car, took out the lightning tube sent from the dangerous goods warehouse, and walked into the temporary laboratory with Wan Peng.

The young man was a little nervous and his legs trembled involuntarily.

The deputy director in charge of criminal investigation and the political commissar of the detachment were sitting next door. Han Bo didn't want him to leave a bad impression on his leader, so he carefully placed Lei Guan on the operating table. While preparing reagents, he smiled and said, "Wan Peng, I suddenly remembered a classic plot in Hong Kong movies."

"Movie?"

"A policeman found a bomb, wiped his sweat, looked at the bomb in front of him, and said to the officer on the walkie-talkie, 'I have good news and bad news, which one do I want to hear?' The officer said to listen to the bad news first, and often said that the bad news is that there is a fucking bomb in this damn box!"

At this time, I was in the mood to joke, but I even sweared in a bad mood. The phone was on the handset-free phone, and I could hear it clearly here. Director Tang, Director Cui and Director Tan of the Provincial Department’s Criminal Investigation Bureau couldn’t help but laugh.

Han Bo looked up at Wan Peng, and said vividly: "The chief asked good news. The police said the good news is that we still have one minute to pray that it will not explode. Then quickly find a bomb disposal expert and use the walkie-talkie to command remotely. You heard that I must not be nervous, open the box first and take a look at the structure..."

In the hero story, Wan Peng is no longer so nervous.

How could Director Lan not know his good intentions? Standing in front of the phone and looking at the two people on the TV screen, he couldn't help but smile: "There are red and blue lines. It's hard to decide which one to cut is like a standardized device."

"So the statement of bomb disposal is inaccurate."

Han Bo took over the conversation and picked up Lei Guanxiao and said, "When facing a bomb, the first thing that comes to mind is not to dismantle it, that is something that can be done in the movie. The correct way is to evacuate all the people around the bomb and go as far as possible. The second step is to judge the type of detonation device and the power of the explosives of the bomb.

This judgment is not to wear a bomb robe and walk up without hesitation. If you have the conditions, use a robot and control it remotely from a distance. If you don’t have the conditions, you have to think of other ways. In short, it is very unwise and stupid to walk over and pick it up and check it.

If it is confirmed that it is remotely controlled, technical measures must be taken to block the surrounding wireless signals and then transfer them after ensuring that the remote control device loses its function; if it is something else, transfer them directly and transfer them to a place where no one is allowed to destroy and detonate; if the detonation device is so complicated that there is no confidence in safe transfer, or if it does not have time to transfer regularly, then destroy them on the spot.

It is impossible to see a strange thing when an explosive is found, the bomb disposal expert will immediately go out with small pliers to cut the wires. In fact, most of the explosives are detonated on the spot. One by one, one dies, and then it is a joke. At most, it can be pulled out. The lightning is pulled out quickly. So there are no so-called bomb disposal experts at home or abroad, only explosion-disposal experts."

"The explosion-proof experts are not waiting for all kinds of news about the discovery of explosives every day in the movie, and they do nothing all day."

Director Lan added with his arms holding his arms: "In fact, the most important job of explosive discharging experts is to make explosives, and the best maker is the best Explosion discharging agent. If I make a bomb, if I am determined not to let someone disassemble it, he will not be able to remove it even if I beat him to death. If I disassemble it for 100 times and explode it for 100 times."

"Director Lan, you won't create bombs all day in Jiangcheng Bureau, right?"

"Of course not in the bureau. There are some blasting projects in the city and professional civil blasting companies. I have the opportunity to participate. For example, how many lightning tubes are needed to be installed in an old building, how much explosives are needed, and directional blasting is much higher in technology than creating an ordinary bomb."

"Next time I have the chance to take me to see."

"no problem."

"Director Cui, although there is no blasting project in our Nangang, the military sub-district and the armed forces of various districts and counties have to destroy some expired ammunition every year. Can you two help us coordinate? Let the police officers of our technical brigade go and take a look when they are destroyed next time."

This kid is doing such a dangerous job, not only joking with Lan Jingwei, but also not forgetting to apply.

It is not a bad thing to let the technical police know how to destroy ammunition, Director Cui agreed: "Yes."

"Thank you, Director Choi."

"Don't thank you, do serious business, be careful."

"clear."

The movements were cautious and thrilling.

All the technical police officers at the unit came in, standing behind Director Cui, staring at the TV screen, so nervous that they didn't dare to breathe.
