Soon, Brother Song led Zhao Zhishan and Jiang Ming to the technical brigade office. After explaining the situation to the head of the technical brigade, he found a patient and friendly female colleague to come over and enlighten the old couple, hoping that they could solve the problem as soon as possible.

Calm down your mood and don't reveal any flaws when you call.

Then, he took Qi Yuan to leave temporarily. After reporting the situation to Su Ping and Xun Mu, he took Qi Yuan to smoke in the smoking area in the corridor.

"Okay, Xiao Qi," he exhaled the smoke. After a moment of silence, Brother Song suddenly praised him: "At first, I just thought something was wrong with Zhao Nanyun. There seemed to be something wrong. I didn't even think about her falling into a pyramid scheme. You are so smart.

Very good."

Qi Yuan smiled sheepishly and said: "Maybe it's because I have little contact and don't know much, so I won't be bound by too many possibilities. I just take it for granted. It's just that sometimes it's subconscious.

Of course, it might be close to the truth."

Brother Song nodded lightly: "After you reminded me, I also felt that this possibility was very high, so I agreed with your guess. Of course, no matter whether your guess is right or wrong, it is quite necessary to make a positioning."

Qi Yuan hummed, and he also understood that no matter what the truth was, the most important next step was to determine the whereabouts of Zhao Nanyun.

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

"What's the specific situation?" Su Ping asked.

Brother Song had just briefly reported the situation before, but now that the two of them were in front of him, he told them everything in detail.

After listening, the two looked at each other and said nothing.

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

Su Ping shook his head: "I thought differently before. The purchase limit is restrictive. The difficult thing to buy is oil, not oil barrels. Oil barrels can be purchased directly on a certain treasure. There are no restrictions.

As for what was inside, the laboratory examination also found that it was not gasoline, but diesel. Compared with gasoline, the purchase conditions for diesel are undoubtedly much looser, and it is easier 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, but after hearing his question, he explained directly: "Actually, whether it is gasoline or diesel, it is not easy to ignite. Under normal circumstances, most of what ignites is volatile

The resulting steam, mixed with air, will burn easily when exposed to an open flame.

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

In addition, in addition to motor vehicles, there are also many machines that need to use diesel. Although they are rare in cities, their utilization rate in rural areas is still quite high, such as diesel lawn mowers, diesel generators, etc.

Of course, there are some that use gasoline, but relatively speaking, diesel is the most common.”

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

After understanding 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 point in buying it directly in small buckets.

question……

In other words, we probably won’t be able to find the specific source of the diesel, right?”

"You can say that." Xun Mu took over: "But at the same time, it also led to another clue. As long as this problem is solved, we can take a big step closer to the truth."

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

"The purpose of the murderer preparing this diesel." Su Ping said calmly: "It is also unrealistic to directly purchase two large barrels of 160 liters of diesel. No gas station will sell such a large amount of diesel to an individual at one time.

In other words, the perpetrator is different between oil barrels and diesel, so what was his purpose of buying diesel? If it was just to dump the body, the gasoline barrel was actually enough."

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

Perhaps in our eyes, the murderer's behavior is meaningless, but this is not necessarily the case in the murderer's mind... In short, we should not infer the murderer's motives based on the results, but should analyze the relationship between his behavior and

Prepare and deduce along the way.

For example, we think it is enough to put the body in an oil drum and bury it in the mountains. Filling it with diesel fuel makes no sense at all, but it makes the transportation more difficult...

But the murderer may not understand this way. What if he simply wanted to use diesel to cover up the smell of the corpse? What if he became a little nervous after the murder and was extremely afraid that the matter would be exposed, so he made preparations that he thought were complete, or even repeated, redundant and futile.

Woolen cloth?"

Qi Yuan thought seriously.

This issue was actually discussed by Su Ping and Xun Mu at the scene as early as yesterday morning.

Therefore, he believed that with their qualifications and experience, they would obviously not make such a mistake and fall into this misunderstanding of thinking that was obviously due to lack of experience.

These words were purely meant for him to listen to and guide him.

This is exactly where he is lacking.

And what he lacks in many things is that Xun Mu and Su Ping are not always so deliberate and give long explanations with examples. Usually they just mention it and let him think about it by himself.

In other words, his problem is actually quite fatal. If it cannot be overcome, it may be difficult to improve, or if there are not enough tips, it may be difficult to overcome it in a short period of time.

So he thought very seriously.

Seeing this, Su Ping and Xun Mu looked at each other, smiled softly at the same time, and said nothing more. They just asked Brother Song to smoke together, leaving Qi Yuan enough time and space to think slowly.

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

"Let's go and have a look." Su Ping said.

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

As soon as he entered, he saw that Xiao Gao was tinkering with something. If he looked carefully, he saw that Jiang Ming's mobile phone was connected to a data cable. Obviously, Xiao Gao was connecting the computer to the mobile phone to facilitate tracking of data and locating the other party's signal. At the same time,

It is also convenient for monitoring call content.

When he saw Xun Mu and the others, Xiao Gao didn't stop moving. He 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 looked at each other again, nodded slightly, and Xiao Gao connected an extra pair of headphones.

"Okay," the debugging was completed quickly. Xiao Gao looked at Jiang Ming and said with a smile: "You can call me. Just relax as you normally would on the phone. In addition, my colleague will be sitting next to you.
Chapter completed!
