Don't take the bean bag as a police dog

Chapter 142 Looking for help
While eating, Zuo Dongliang asked how Li Lei's technical investigation department analyzed the composition of these residues.

Li Lei blurted out that he used a spectrum analyzer to make a preliminary judgment, and then analyzed it with other instruments that he didn't even know.

Li Lei said that this analysis can only be done on the premise of a large sample size, and the high-end technical equipment of the Technical Investigation Division can't do anything about such a small amount of engine oil residue.

Zuo Dongliang felt that he was still a little unwilling. The preliminary physical evidence was already in front of him. If he could further analyze the properties of the engine oil, and then determine the specific model and brand of the engine oil, the scope could be further narrowed down.

Being able to further narrow the scope and reduce the one-day handling time is a good thing for colleagues and even citizens.

After the meal, Zuo Dongliang decided to ask Shen Jing. After all, Shen Jing is a university physics teacher and may have more professional instruments.

Ever since I chatted with Shen Jing when I was on the night shift that day, the chat between Shen Jing and Zuo Dongliang returned to normal, and I can meet her today.

Zuo Dongliang sent a message to Shen Jing with the current idea of ​​analyzing the components of engine oil residue.

After a while, Shen Jing sent a message saying: "You brought the residue, our laboratory has a more sophisticated spectrometer."

Zuo Dongliang was overjoyed when he heard the news.

Of course, this is evidence related to the facts of the case, and it needs to be analyzed on social instruments, which requires a process.

After Zuo Dongliang told Li Lei of this idea, Li Lei immediately sealed the iron water pipe with a large airtight bag, and handed it to Zuo Dongliang, saying that since it was possible, he had to do something special. will go.

In this way, Zuo Dongliang came to Diandong University in a dog cart.

Zuo Dongliang's car stopped right next to the quiet Golf R hot hatch.

It is not appropriate to put the bean bag on duty, so I can only come with Zuo Dongliang in a dog cart.

Shen Jing saw Zuo Dongliang wearing a uniform and showed admiration. From Shen Jing's point of view, Zuo Dongliang was the most decent when he was wearing a uniform. The clothes he bought before, no matter how expensive they were, didn't seem as pleasing to the eye as the uniform.

Zuo Dongliang took out the steel pipe from the co-pilot, pointed to the black engine oil residue on the thread at the end and said: "That's it, we want to see the oil composition in this residue, it's best to specify the model, so that we can The scope of the case has been greatly reduced.”

Shen Jing pretended to be unhappy and said, "You and I will talk about work as soon as we meet, can we talk about something else first?"

Zuo Dongliang suddenly realized, patted his head, and said with a face of shame: "Sorry, sorry, Mr. Shen, my mind is full of cases, I am serious, I invite you to dinner."

Shen Jing snorted, and then said, "You're wearing a uniform and you're bringing your police dog with you. It's inconvenient. You wait here. I'll go to the cafeteria to get some food. We'll eat in the back of the car. Have you eaten the bean buns?"

As expected, Shen Jing is a dog lover and always thinks about the warmth and comfort of dogs.

Shen Jing said that she still had the dog food she had just bought in the car, and Zuo Dongliang said that the bean buns had already been eaten as extra meals, and they were not tender at all, so Shen Jing gave up.When the cool wind blows in early autumn, Zuo Dongliang suddenly feels that it is actually quite good to keep such a distance from Shen Jing, like a couple, but like ordinary friends, at least Shen Jing will not ignore himself because of anger.

If it was a gluey couple relationship, it is estimated that Zuo Dongliang would have angered Shen Jing when he opened his mouth just now.

Waiting for Shen Jing to call for food from the cafeteria, the two chatted while eating on the trunk of the car.

Shen Jing's car is still so cool. As one of the rare girls in high-speed trains, she talked about car engine oil, and Zuo Dongliang only knew about those car oils currently on the market, but these high-end performance car oils, Zuo Dongliang had never heard of it.

Zuo Dongliang was dumbfounded when he heard about Limo oil from Germany and Sakura oil from Japan.

Zuo Dongliang said that his golf GTI also wanted to change to this kind of high-end engine oil, but Shen Jing waved his hand and said that it was completely unnecessary.

Shen Jing said that those high-end engine oils, although advertised as high-end engine oils, are all weaker than racing oils and stronger than ordinary civilian use. In fact, there is not much difference, but there are some differences in ingredients.

Zuo Dongliang felt that when he chatted with Shen Jing, he always had an attitude of looking up, let alone physics, even if it was about modifying cars, Zuo Dongliang could only listen to the teaching.

"I think your investigation is very interesting. You even thought of using a spectrum analyzer. It feels like those investigation TV dramas." Shen Jing saw that Zuo Dongliang could only listen to it, so she praised Zuo Dongliang.

Zuo Dongliang shrugged and said, "In fact, our city bureau also has this kind of spectrometer, but its performance is limited and not precise enough. I'm afraid it can only be analyzed by the one in your university laboratory."

Zuo Dongliang only spoke half of what he said. In fact, it stands to reason that the technical investigation department of the provincial department may have an instrument that can analyze it, but if it involves the provincial department to handle the case, it is equivalent to handing over the case to the provincial department for handling , I can't keep up with this face.

Shen Jing said that the spectrum analyzer at Diandong University is indeed laboratory-level, not the hand-held ones that are sold in the market, and there are requirements for the amount of samples. Quantity requirements are not large.

Shen Jing introduced it for a while, and told Zuo Dongliang that although she could help with this, she was not sure that she could get accurate data with the laboratory spectrometer, and she said he could only do his best.

The tone of Shen Jing's speech at this time is still not quite like the content between the couple before, but more like a chat between good friends.

When Zuo Dongliang wanted to mention that the last time they had dinner together, Zuo Dongliang didn't cater to Shen Jing's parents according to what Shen Jing had prepared for him, Shen Jing seemed to notice it and changed the topic to other aspects.

Shen Jing talked about his schnauzer. He said that his dog was sick recently, but the pet hospital near his home couldn't find anything. Zuo Dongliang probably knew what disease Shen Jing's dog was suffering from from Shen Jing's description. But he still didn't say it.

Listening to Shen Jing's description, that schnauzer suffered from severe ovarian cysts because she had never given birth, and the time is running out.

This is a dog of more than ten years, and many complications due to old age are mostly incurable.

Zuo Dongliang believes that if Shen Jing is told this unfortunate news, it will probably make Shen Jing very sad.

"Don't worry, your dog will definitely get better, just don't let it do too much strenuous exercise." Zuo Dongliang's words can only be said for this sake.

Zuo Dongliang sighed secretly in his heart, all dogs will have such a day, just like Yang Yong, he has already experienced four police dogs, some were sacrificed, and some were old.

There is also organ failure due to long-term drug search like the Magou Haifeng that Yang Yong took before.

"I hope it's not a big problem as you said." Under Zuo Dongliang's comfort, Shen Jing suddenly felt better.
