Chapter 875

Zhang Dinghui was stunned for two seconds, sat up, put on a piece of clothing, and leaned against the head of the bed: "So, the conclusion now is that it is definitely a remote-controlled bomb, and the perpetrator is still on the run, right?"

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

"What plans do you have?" After Zhang Dinghui finished speaking, he remembered the experience during the day and changed the question: "What plans does Jiang Yuan have?"

"Jiang Yuan's suggestion is still to proceed step by step. Now that the circuit board has been found, let's see if we can find the manufacturer of the circuit board, and then trace the supply and sales situation to see if we can find the final purchasing user. In addition, they also found other fragments of the remote-controlled bomb and are verifying them."

"So it's called a remote-controlled bomb now." Zhang Dinghui said, still having questions to ask, but then changed his mind and said: "Let's have a conference call. Get the comrades at the scene to join in for a meeting. Does Jiang Yuan have time?"

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

"En." Zhang Dinghui hung up the phone, put on his jacket, got up, and said to the person on the pillow: "I'm going to the living room for a video conference; you go to sleep."

"Alright, don't go to sleep too late." His wife turned over.

"I hope so." Zhang Dinghui smiled, then sat down next to the phone in the living room, knowing in his heart that tonight would be a sleepless night.

Soon, the phone rang.

Zhang Dinghui pressed the speakerphone and said steadily: "I am Zhang Dinghui."

On the phone, the bureau chief, Jiang Yuan, Song Tiancheng, and others greeted Zhang Dinghui one by one.

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

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

"How... how are you sure?" Zhang Dinghui's sleep state was completely lifted, and his throat felt dry. Jiang Yuan's answer, although indeed within Zhang Dinghui's expectations, also shocked him; this was almost the worst possible answer.

Jiang Yuan said: "This is a speculation. We have now found fragments of all the key parts of the remote-controlled bomb. Through the identification of these pieces of evidence, I believe that the materials used by the perpetrator are relatively simple and easy to obtain."

Jiang Yuan's voice carried a slight fatigue: "Among the materials used by the perpetrator for the remote-controlled bomb, the hardest to obtain is the explosive. But from our interrogation, the mine owners, partners, and some management personnel of the surrounding factories and mines all like to gamble here. When these gamblers lose, they can use anything as collateral, including their wives and children, and also things like explosives and detonators."

"There is such a thing?" Zhang Dinghui's voice seemed extremely shocked.

Jiang Yuan didn't care whether he knew the situation before or not, and just continued: "The surrounding factories and mines often have private explosive transactions. 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."

"There is such a thing!" This time, Zhang Dinghui was even more shocked when he heard it.

"In short, because the raw materials are easy to obtain, I believe that when the perpetrator made the remote-controlled bomb, he likely didn't just make one. When he bought the materials, especially the explosives, he probably bought extra, and maybe even made an extra remote-controlled bomb with a low explosive charge for experiments..."

Zhang Dinghui felt cold just hearing it: "So, he might have more than one remote-controlled bomb in his hands, maybe two or three?"

"Yes. It's highly likely."

"This..." If you say Zhang Dinghui was panicked, that wouldn't be the case, but to ask him to come up with any ideas in a short time, he couldn't do that either.

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

"We currently have several main directions of attack." Jiang Yuan didn't wait for Zhang Dinghui's response. He was a person from the Ningtai County Bureau and didn't need to take care of Zhang Dinghui's emotions too much. And before making the call, Jiang Yuan had already thought for a long time. At this time, Jiang Yuan followed his own train of thought and said: "Two paths are already being pursued. One is interpersonal relationships, and the other is investigating the source based on evidence. Both are being checked, but there are no clues yet."

Detachment Captain Wang Sheng took the initiative to say: "This is the work of our criminal investigation detachment. One is to check the motive, and the other is to check the preparation. Unfortunately, neither has made a breakthrough."

Zhang Dinghui said "En" and said: "Understood."

Wang Sheng listened to Zhang Dinghui's voice and quickly continued: "We are continuing to investigate based on some newly discovered evidence. In addition, we have also fully utilized special informants, but there is no useful news or clues for the time being. Finally, a small number of criminal police are also verifying other clues, such as possible routes for selling stolen goods, escape routes, and have also visited the masses around the gambling den..."

Zhang Dinghui naturally spoke kindly to the "grassroots cadres." If he wanted to scold someone, he would have to scold the bureau chief; he couldn't scold the criminal investigation detachment.

Jiang Yuan took over the conversation and said: "Now, there are new investigation directions, and the investigation forces have all been sent out, but how long it will take to get news is still uncertain, so we can only wait with peace of mind."

This could only be said by him, which was what he said in the tent during the day.

Zhang Dinghui was like someone who lost an argument and came back at night to carefully review it, so he said: "For ordinary cases, catching the perpetrator is indeed not that urgent, but now that it's confirmed there is a bomb out there, how can we guard against it? What is this perpetrator thinking? If we don't catch the person, it's truly unsettling."

"We have no way to guess the perpetrator's thoughts for the time being. But if we want to guard against it, it's not that there's no way at all." Xu Taining's voice came over the phone.

Wang Sheng quickly introduced him, acting as a narrator.

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

"Absolute position control of key areas." Xu Taining answered with this sentence and then explained: "That is to increase the... alert level for key areas. For example, strengthen security for important departments such as the municipal government and the municipal bureau, and suspend some external work. For places with dense crowds like stadiums and shopping malls, they can be closed directly. For hub nodes that cannot be closed like hospitals and train stations, increase security efforts to ensure that private entry is prevented..."

"This is equivalent to canceling all the functions of the government." Zhang Dinghui said speechlessly: "It would be better to just stop all the buses."

"That's a good idea; that's exactly what I mean." Xu Taining's affirmative attitude could be felt through the phone.

Zhang Dinghui was between laughing and crying: "We can't do things like that."

Xu Taining suddenly became a bit more serious and said: "If we seal the city immediately and manage the city in multiple blocks, it is very likely to cause the separation of the perpetrator and the bomb. If we are lucky, it is easiest to take down the perpetrator without damage."

"How long will that take?"

"A few days at the shortest, two weeks at the longest."

"How could it take two weeks? Even one week is not possible." Zhang Dinghui immediately denied it.

"There is another possibility." Xu Taining didn't finish speaking, but continued to tap like he was knocking on gold coins: "If the perpetrator lives in the suburbs or the countryside, sealing the city might be a waste of money."

"It costs more money, and it might be a waste of money?" Zhang Dinghui fully understood what "Xu Taining, who is particularly good at spending money" meant at this time, and at the same time, he also understood Xu Taining's meaning.

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

After hanging up the phone, Wang Chuanxing, who was guarding the phone table, couldn't help but say: "The conclusion is the same as yesterday; another meeting wasted."

Xu Taining glanced at him irritably: "That's because Captain Jiang managed upwards; otherwise, you would have gotten a different conclusion than yesterday, realizing that you didn't waste a meeting."

Jiang Yuan waved his hand, opened a computer without a word, and continued to compare the circuit boards.

According to the plan, he was to find the manufacturer of the circuit board by comparing it, then find the distributor, and then see if he could find the end buyer. This plan sounded flawless; the only problem was that the circuit board was the wreckage of an explosion.

The remaining volume was about the thickness and length of two fingers, and it was damaged, and it was a discontinuous part pieced together from several fragments. Trying to distinguish the manufacturer from it might not be too difficult—LV4 explosion trace identification should be enough—but trying to find the distributor and the channel would be very difficult.

Times are different now; circuit boards can also be bought online. If you only look for the manufacturer and not the distributor, it will take a lot of time.

Of course, even if you can only determine the manufacturer, it will be helpful for the investigation of the case. After all, these circuit boards are mostly produced and OEM-ed by small and medium-sized enterprises, and the sales channels won't be very wide. Maybe it will really only take two weeks to get a conclusion...

If you don't want to wait two weeks, you need LV5 or higher explosion trace identification.

Jiang Yuan's temporary +1 skill for today hadn't been used yet, so he was currently configured with LV6+1, making it LV7 explosion trace identification. So, under the blank stares of the Meiyang City trace inspection team...

Jiang Yuan, he looked at the circuit board, he looked at the circuit diagram, the circuit board was broken, the circuit diagram was messy, the circuit diagram was mixed with the circuit diagram, the circuit board was mixed with the circuit board, but in the final analysis, one circuit board only corresponds to one circuit diagram.

True love in the semiconductor world is nothing more than this.
