Soon, Brother Song led Zhao Zhishan and Jiang Ming to the office of the technical brigade, and after explaining the situation to the person in charge of the technical brigade, he found a female colleague with patience and affinity to come over to enlighten the old couple, hoping that they could calm down as soon as possible and not show flaws when calling.

Then, he pulled Qi Yuan to leave temporarily, and after reporting the situation to Su Ping and Xun Mu, he pulled Qi Yuan to smoke in the smoking area in the aisle.

"Okay, Xiao Qi," spat out the smoke, and after a moment of silence, Brother Song suddenly praised him: "At first, I just felt that something was wrong with Zhao Nanyun, and there seemed to be a problem, but I didn't think about her falling into a pyramid scheme, you have a very flexible brain." ”

Qi Yuan smiled embarrassedly and said: "Maybe it's because I don't have much contact and don't know much, but I won't be bound by too many possibilities, I just think so, but sometimes this kind of subconscious assumption may be just close to the truth." ”

Brother Song nodded lightly: "As soon as you reminded me, I also think that this possibility is very high, so I agreed with your guess." Of course, whether you guess right or wrong, a positioning is quite necessary. ”

Qi Yuan snorted, he also understood that no matter what the truth was, the next most important part should be to determine Zhao Nanyun's whereabouts.

After chatting for a while, Qi Yuan saw Xun Mu and Su Ping coming side by side.

"What's going on?" Su Ping asked.

Brother Song had only reported the situation before, but now the two of them were in front of him, and he told the two of them everything about it.

After listening, the two looked at each other and didn't say anything.

After a while, Brother Song asked again: "Have you found out the source of the gasoline barrel?" ”

Su Ping shook his head: "I thought about it before, it was oil that was restricted and difficult to buy, not oil drums." The oil drum thing, you can directly order and buy it on a treasure, and there is no limit.

As for the contents inside, after laboratory identification, it was also found that it was not gasoline, but diesel. Compared with gasoline, the purchase conditions of diesel are undoubtedly much more relaxed and easy to get. ”

"Diesel?" Qi Yuan was a little puzzled and asked, "Why is diesel so easy to buy?" ”

"Because diesel is not flammable." Brother Song originally frowned, and when he heard his question, he explained directly: "In fact, whether it is gasoline or diesel, it is not easy to ignite, and under normal circumstances, most of the ignited vapors are volatilized, which are mixed with air, and are extremely flammable in case of open flames.

To put it simply, diesel is not volatile, so it is difficult to burn compared to gasoline, and the danger is naturally much lower, and the restrictions are not so strict.

In addition, in addition to motor vehicles, there are also a lot of machinery that need to be applied to diesel, although it is rare in the city, but the utilization rate in the countryside is still quite high, such as diesel lawn mowers, such as diesel generators, and so on. Of course, there are gasoline users, but there are still more diesel. ”

"I see." Qi Yuan suddenly realized that he really didn't know much about the difference between gasoline and diesel.

After figuring out this problem, he also frowned: "In other words, if you want to get diesel, there are actually many ways, even if you can't get a large amount at one time, there is no problem in buying a small keg directly......

In other words, we probably won't be able to find out where the diesel comes from, right? ”

"So to speak." Xun Mu took over: "But at the same time, it also leads to another clue, as long as this problem is solved, we can also take a big step closer to the truth." ”

"Huh?" Qi Yuan was very curious: "What clue?" ”

"The purpose of the murderer preparing these diesels." Su Ping said lightly: "It is also unrealistic to directly buy two large barrels of 160 liters of diesel, and no gas station will sell such a large amount of diesel to individuals at one time."

In other words, the perpetrator of the oil drum and diesel fuel is different, so what is the purpose of buying diesel oil? If it's just to throw a corpse, having a gasoline drum is enough. ”

Xun Mu took over and said: "In addition, there is another misunderstanding of thinking - the purpose is the goal, and it has nothing to do with whether it can be achieved.

It may seem to us that the murderer's actions are meaningless, but this is not necessarily the case in the murderer's mind...... In short, we should not deduce the murderer's motives from the results, but from his actions and preparations.

For example, we think that it is enough to put the body in an oil drum and bury it deep in the mountains, and then fill it with diesel fuel does not make any sense at all, but only increases the difficulty of transporting it......

But the murderer may not have understood it this way, what if he simply wanted to cover up the smell of corpses with diesel? What if he becomes a little neurotic after the killing, and is extremely afraid that things will be revealed, so he makes self-righteous and even repetitive, superfluous, and futile preparations? ”

Qi Yuan thought seriously.

This issue, as early as yesterday morning, at the scene, in fact, Su Ping and Xun Mu had discussed it.

Therefore, he believes that with their qualifications and experience, it is clear that they will not make such a mistake and fall into this kind of thinking mistake that is obviously inexperienced and taken for granted.

These words are purely spoken to him and to guide him.

That's exactly what he's lacking.

And what he lacks is that he doesn't necessarily have Xun Mu and Su Ping so deliberately, and gives long examples, which is generally just to mention it and let him think about it for himself.

In other words, his problem is actually quite fatal, if it can't be overcome, I'm afraid it will be difficult to improve, or there are not enough points to improve, and it will be difficult to overcome in a short period of time.

So he thought quite seriously.

Seeing this, Su Ping and Xun Mu glanced at each other, smiled lightly at the same time, and didn't say anything more, just beckoned Brother Song to smoke together, leaving enough time and space for Qi Yuan to think slowly.

After a long time, the policewoman came out, said hello to Xun Mu and them, and then reported: "The two of them have almost stabilized their emotions at this time, and they can talk to the target at any time as planned, do you want to go in and have a look?" ”

"Let's go, let's see." Su Ping said.

Brother Song touched Qi Yuan and brought him back to his senses, and then followed Su Ping and Xun Mu into the big office of the technical brigade.

As soon as I entered, I saw that Xiao Gao was tinkering with something, and then looked carefully, Jiang Ming's mobile phone was connected to a data cable, obviously, Xiao Gao was making the computer and the mobile phone establish a connection, which was convenient for tracking the data, positioning the other party's signal, and also convenient for monitoring the content of the call.

Seeing Xun Mu and them, Xiao Gao didn't stop, only raised his head to say hello and asked them if they wanted to monitor the call.

After thinking about it, Xun Mu and Su Ping glanced at each other again, then nodded slightly, and Xiao Gao connected more pairs of headphones.

"Okay," soon after the debugging was completed, Xiao Gao looked at Jiang Ming and said with a smile: "You can call over, relax, just like you usually call, in addition, my colleague will sit on the side, if there is any prompt, I will remind you by handwriting." ”
