Chapter 895 True Love
Zhang Dinghui was stunned for two seconds, then sat up, put on a coat, and leaned against the head of the bed: "So, the conclusion now is that it was definitely a remote-controlled bomb, and the murderer is still on the loose, right?"

"Yes." The person on the other end of the phone was Director Deng Jiabin. He was also woken up from his deep sleep and had just been asked a similar question. At this time, he could only give this simplest and most direct answer.

"What are your plans?" Zhang Dinghui said, and then he thought of his experience during the day and changed the question: "What are Jiang Yuan's plans?"

"Jiang Yuan suggested that we proceed step by step. Now that we have found the circuit board, we will see if we can find the manufacturer of the circuit board, and then trace back the supply and sales situation to see if we can find the final purchaser. In addition, they also found fragments from other remote-controlled bombs and are also verifying them."

"Now it's called a remote-controlled bomb." Zhang Dinghui said, and he still had some questions to ask, but then he changed his mind and said, "Let's have a conference call and get the comrades on the scene to have a meeting together. Does Jiang Yuan have time?"

Deng Jiabin knew what Zhang Dinghui meant and said, "I'll communicate with them and try to get Jiang Yuan to attend the meeting."

"Yeah." Zhang Dinghui hung up the phone, put on his jacket, stood up, and said to the person beside him, "I'm going to the living room to have a video conference. You go to sleep."

"Okay, don't go to bed too late." My wife turned over.

"I hope so." Zhang Dinghui smiled and sat down next to the telephone in the living room. He knew in his heart that tonight would be a sleepless night.

Soon, the phone rang.

Zhang Dinghui pressed the hands-free button and said calmly, "I am Zhang Dinghui."

On the phone, the director, Jiang Yuan, Song Tiancheng and others greeted Zhang Dinghui respectively.

Zhang Dinghui also responded politely, and then said: "I know time is tight, let's have a quick meeting. Jiang Yuan, is there a remote-controlled bomb outside now?"

"Yes." Jiang Yuan's answer was firm and powerful.

"How...how did you confirm that?" Zhang Dinghui's sleep state was completely awakened, and his throat felt dry. Although Jiang Yuan's answer was indeed within Zhang Dinghui's expectations, it also frightened Zhang Dinghui. This was almost the worst answer.

Jiang Yuan said: "This is a guess. We have now found the debris of the key parts of the remote-controlled bomb. Through the identification of these evidences, I believe that the materials used by the criminals are relatively simple and easy to obtain."

Jiang Yuan's voice was slightly tired. "Among the materials used to make the remote-controlled bombs used by the murderer, explosives are the most difficult to obtain. But from our interrogation, we found that the mine owners, partners, and some managers of the surrounding factories and mines all like to gamble here. If these gamblers lose, they can use anything as collateral, including their wives and children, as well as explosives, blasting tubes, and other things."

"Is this true?" Zhang Dinghui's voice seemed extremely shocked.

Jiang Yuan didn't care whether he knew the situation before or not, and continued: "Many factories and mines around here have been trading explosives privately. This thing is not easy to approve for some factories and mines, but it is indispensable in the production process, so some mine owners choose to buy it at a high price."

"How could this happen!" This time, Zhang Dinghui was even more shocked.

"In short, because the raw materials are easy to obtain, I think that when the murderer made the remote-controlled bomb, he would most likely not make just one. When he purchased materials, especially explosives, he would probably buy more. He might even make another remote-controlled bomb with a low charge for experimentation..."

Zhang Dinghui was chilled to the bone after hearing this: "So, he might have more than one remote-controlled bomb in his hand, but two or three?"

"Yes. Most likely."

"This..." It's not that Zhang Dinghui was panicked, but he couldn't come up with any ideas in a short time.

In the living room, Zhang Dinghui poured himself a cup of tea. He hesitated for a moment, wondering whether to delegate power or reiterate the discipline and make strict demands...

"We have several main directions now." Jiang Yuan did not wait for Zhang Dinghui's response. He was from the Ningtai County Bureau and did not need to take care of Zhang Dinghui's emotions. Before calling, Jiang Yuan had been thinking for a long time. At this time, Jiang Yuan followed his own thoughts and said, "There are two paths that are being investigated. One is interpersonal relationships, and the other is to investigate the source based on evidence. Both are being investigated, but there are no clues yet."

Captain Wang Sheng took the initiative to say: "This is the job of our criminal police detachment. One is to investigate the motive for the crime, and the other is to investigate the preparation for the crime. Unfortunately, we have not been able to make a breakthrough in either."

Zhang Dinghui said, "I understand."

Wang Sheng listened to Zhang Dinghui's voice and quickly continued: "We are now continuing the investigation based on some of the latest evidence. In addition, we have also fully mobilized special agents, but there is no useful information and clues for the time being. Finally, there are also a few criminal police who are investigating other clues, such as possible routes for selling stolen goods and escape routes, and they have also visited the people around the gambling house..."

Zhang Dinghui naturally spoke kindly to the "grassroots cadres". If he wanted to scold someone, he would start with the director and would not scold the criminal police detachment.

Jiang Yuan took over the conversation and said, "Now, we have a new direction for investigation and have sent out all the investigation forces, but we are still uncertain how long it will take to get the news. We can only wait patiently."

This is what only he said, and it was what he said in the tent during the day.

Zhang Dinghui looked like someone who had just lost an argument. He came back that night and reviewed the situation carefully. He said, "For ordinary cases, catching the murderer is not that urgent. But now that we know there is a bomb outside, how can we prevent it? What is the murderer thinking? If we don't catch him, we will be unable to sleep or eat."

"We have no way of guessing the murderer's thoughts for now. But if we want to be on guard, it's not completely impossible." Xu Taining's voice was heard over the phone.

Wang Sheng quickly introduced it and acted as a narrator.

Zhang Dinghui instinctively didn't want to talk to Xu Taining, but he couldn't help asking: "If we want to be on guard, what can we do?"

"Absolute position control in key areas." Xu Taining answered this sentence, and then explained: "It means raising the alert level in key areas. For example, important departments such as the municipal government and the municipal bureau should strengthen their vigilance and suspend some external work. Stadiums, shopping malls and other places with dense traffic can be closed directly. For hub nodes that cannot be closed, such as hospitals and railway stations, the security efforts should be increased to prevent unauthorized entry..."

"This is equivalent to abolishing all government functions." Zhang Dinghui said speechlessly: "It would be better to stop running all buses."

"It's a good idea, that's what I mean." Xu Taining's affirmative attitude could be felt throughout the phone call.

Zhang Dinghui didn't know whether to laugh or cry: "We can't do it this way."

Xu Taining suddenly became more serious and said, "If we seal off the city immediately and divide it into multiple blocks for management, it is very likely that the murderer and the bomb will be separated. If we are lucky, it will be easiest to capture the murderer without any damage."

"How long will it take?"

"It could be as little as a few days or as much as two weeks."

"How is two weeks possible? Not even a week." Zhang Dinghui immediately denied it.

"There is another possibility." Xu Taining did not finish his words, but continued to talk like knocking on gold coins, saying: "If the murderer lives in the suburbs or the countryside, sealing off the city may be a waste of money."

"Is it going to cost me more money, and it might be wasted?" Zhang Dinghui now fully understood what "Xu Taining, who is particularly good at spending money" meant. At the same time, he also understood what Xu Taining meant.

Zhang Dinghui then asked a few more questions to his own experts before saying, "Okay, let's do it according to your ideas!"

After hanging up the phone, Wang Chuanxing, who was standing by the phone table, couldn't help but say, "The conclusion is the same as yesterday. Another meeting in vain."

Xu Taining glanced at him unhappily and said, "That was Captain Jiang's management. Otherwise, you would have come to a different conclusion than yesterday and realized that your meeting was not in vain."

Jiang Yuan waved his hand, silently turned on a computer, and continued to compare the circuit boards.

According to the plan, he would find the manufacturer of the circuit boards by comparing them, then find the distributors, and then see if he could find the end buyers. This plan sounded perfect, except that the circuit boards were the remains of an explosion.

The remaining volume is about the same thickness and length as two fingers, and it is still defective, or a discontinuous part pieced together from several fragments. It may not be too difficult to distinguish the manufacturer from it. The LV4 explosion mark identification may be enough. But finding the dealer or the channel is difficult.

Today is different from the past. Circuit boards can also be purchased online. It takes a lot of time to only look for manufacturers instead of dealers.

Of course, even if we can only identify the manufacturer, it will be helpful for the investigation of the case. After all, this kind of circuit board is mostly produced and outsourced by small and medium-sized enterprises, and the market is not very wide. Maybe it only takes two weeks to get a conclusion...

If you don’t want to wait two weeks, you will need an explosion trace identification of level 5 or above.

Jiang Yuan had not used his temporary +1 skill today, so he was currently at level 6+1, and had a level 7 configuration for explosive trace identification. So, in the bewildered eyes of the Meiyang City Trace Inspectors...

Jiang Yuan, he looks at circuit boards, he looks at circuit diagrams, the circuit boards are broken, the circuit diagrams are messy, circuit diagrams are randomly intertwined with circuit diagrams, circuit boards are randomly intertwined with circuit boards, but in the final analysis, one circuit board only corresponds to one circuit diagram.

This is what true love in the semiconductor world is all about.
