Return to 1983 and be a detective

The deceased, Dong Wenming.

Age, 28 years old.

Sex: Male.

Occupation, technician at Longshui Steel Plant.

Cause of death, cyanide poisoning.

Death symptoms: clenched fists, foaming at the mouth, defecation after death...

Xu Shan inspected Dong Wenming's body bit by bit, muttering this information while inspecting it.

He even opened Dong Wenming's mouth and looked to see if he had the kind of poisonous fangs that are exclusive to special agents as shown in TV series.

However, it does not.

Then he looked at the water glass.

This is a ceramic cup given to model workers in the factory on Labor Day. However, this cup does not belong to Dong Wenming, but to the Security Department.

It was because Dong Wenming said he wanted to drink water, so Fang Yongjun went out, took a cup and poured water from the thermos, and Fang Yongjun personally brought it back.

Logically speaking, if Fang Yongjun hadn't poisoned him, it would have been very difficult for others to poison him.

The problem now is that the time is limited to one hour. There is no toxicology analysis here. It should be impossible to analyze whether the water in this glass is poisonous, let alone where the poison was poisoned.

So looking for the source of the poison is a dead end.

Xu Shan decided to find another way to find clues: the people Dong Wenming contacted before his death.

Going back a bit, the people Dong Wenming can contact, apart from the other five people who participated in the interrogation before, are himself and Su Jing, as well as Liang Feng and Fang Yongjun.

So the focus of the investigation should be on these five people?

When Xu Shan was thinking this, his eyes suddenly fell on Dong Wenming. At some point, there were many dead ants around him. These ants all died next to the urine that flowed out after Dong Wenming died.

Xu Shan suddenly thought of a joke from later generations: "Whoever has yellow urine, wake him up."

Only then did he discover that Dong Wenming's urine was yellow and the smell could attract ants, which meant that this guy was probably suffering from diabetes.

Diabetes is called diabetes mellitus in traditional Chinese medicine. The great writer Sima Xiangru suffered from this disease at that time. It manifested itself as being constantly thirsty and wanting to drink water. This is probably why Dong Wenming wanted to drink water.

It's just that these days, people with diabetes are still quite rare. Even diabetes is probably classified as a strange disease. Therefore, Dong Wenming's disease should only be known to a very small number of people.Therefore, the poisoner must grasp the characteristics of Dong Wenming and put the prepared poison into the water. Naturally, he can accurately poison Dong Wenming.

As soon as he understood this, Xu Shan suddenly became enlightened. He patted his head and stood up. He turned around and said to Liang Feng: "Quickly, go and arrest Xiao Song, the clerk who made tea for us. I think the only way to do this is in the thermos bottle." He is the only one who poisoned it."

Liang Feng and Fang Yongjun went out to catch Xiao Song, but Su Jing stayed behind. She had a lot of questions and wanted to ask clearly: "How do you know that Xiao Song is the murderer? It doesn't look like he is a bad person."

Xu Shan did not answer, but asked: "Want to know?"

Seeing Xu Shan's appearance, Su Jing was furious: "You want to talk or not."

"Okay, actually I'm going to tell you even if you don't ask. Do you know what kind of poison the deceased was poisoned to death? It was cyanide..."

"Cyanide? I learned about it in the police academy. It seems difficult to get. Doesn't that mean it's impossible for Xiao Song to get it?"

"Don't rush to overturn my conclusion. You should have learned about the toxicity of cyanide. Just a little bit can poison people. It can be said that the toxicity is quite strong, and the poison spreads quickly. There is basically no cure. So this You must not put too much of what you are planting, otherwise it will easily poison a large area."

Su Jing was impatient and could not tolerate Xu Shan being surrounded by clouds and mountains: "Don't go around, just tell me why."

"Okay, I mean, the poison was not put in the water cup, but in the thermos. There are many people who have access to the thermos. But in the short period of time from when we drank tea to when Dong Wenming was poisoned, how could There are very few people who poisoned him, and it might even be Xiao Song alone."

"What you said makes sense, but it was Fang Yongjun who poured Dong Wenming's water. There are so many thermos pots in the security department. How could he be so accurate and predict that Fang Yongjun would get the poisoned pot?"

"It's very simple. Just pour out all the water in the other kettles. If there is water in only one kettle, what will the person fetching water do?"

"I see, you have a good mind..." Su Jing felt a little regretful at this point, "It would be great if you had used this brain on the right path from the beginning."

Xu Shan knew what Su Jing was regretting, but it was difficult for him to answer the question, and the situation suddenly became awkward.

He had no choice but to deflect his embarrassment and said: "Why did it take so long to arrest someone? Did that Xiao Song escape?"

Only then did Su Jing realize that if she just led people in the security department, it wouldn't take that long.She then became nervous. If Xiao Song escaped here, it would prove that their newly established criminal police team was lacking in ability. Originally, many people were questioning their criminal police team at this time. She didn't want to admire her. Team Liang was blamed for this.

Thinking of this, Su Jing pulled Xu Shan directly out of the interrogation room.

As soon as they went out, they saw Dong Chunsheng and Ding Zeren leading a large number of people to block Liang Feng and Fang Yongjun. Although these people did not speak, the atmosphere was tense, obviously because they did not want Liang Feng to take away the little boy. Song Dynasty.

The two sides are directly confronting each other. Although both sides have restrained themselves now, if this continues, the situation will become very bad.

Xu Shan's head was about to split. It was such a bad year. He shouldn't have come to Longshui Steel Plant. Now he was fine. He was completely stuck in it.

He instinctively wanted to retreat, not wanting to get involved in this matter, but Su Jing couldn't help but drag Xu Shan to stand on Liang Feng's side.

When Dong Chunsheng saw Su Jing and Xu Shan joining the confrontation, he frowned and said, "Liang Feng, I'm not trying to embarrass you, I'm just worried that you got the wrong person. You arrested the wrong Dong Wenming before, which caused Dong Wenming to die." It's so dead, and now you are going to take away this Xiao Song. If you make another mistake and word gets out, people will say that our factory does not take care of our young people. This is hard to say, but it is hard to say."

Ding Zeren also echoed: "Director Dong is right. If you want to take the person away, you must set up a guarantee, otherwise we will never hand the person over to you."

Xu Shan thought to himself, no wonder the rule of law is difficult to implement these days. There are such intricate relationships in a small steel factory, let alone the entire society?

He glanced at Liang Feng secretly. Liang Feng's calm expression before finally disappeared. He reached for his waist and pulled out the pistol with a swish.

When Xu Shan saw it, his heart went cold. Has this reached the point where he needs to use a gun?This is not fun to fight.
