In early autumn, the night of the full moon, the gentle evening breeze, the silent evening bell.

After a hard day's work, I made an appointment with three or five friends and sat in front of a relatively secluded barbecue stall, feeling the cars behind me and the crowd coming and going.

Eating crayfish and drinking beer together is really a very happy and pleasant thing. We were supposed to be shuttling between the crowds and traffic, but we chose to sit here and eat barbecue, and this stark contrast made us feel more relaxed for a while.

"Cheers!"

Three glass bottles of beer touching each other is a simple and difficult thing for adults.

Simply put, it's easy for three people to have a meal on the side of the road. The difficulty is that it is not easy to get together three people to eat a meal on the side of the road.

"I really can't figure out why anyone likes to eat crayfish so much."

Ren Qiushi gulped down mutton skewers, and felt very puzzled when he saw Li Meng wearing disposable plastic gloves and peeling them for a long time, only getting a little bit of meat.

"Indeed, this thing is expensive and has little meat, or this lamb skewer is more comfortable." I picked up a lamb skewer and said faintly.

Li Meng finally put a piece of crayfish meat into his mouth with great difficulty, and showed a very satisfied smile.

She picked up another crayfish and said to us slowly: "That's because you don't know the fun of eating crayfish, eating crayfish enjoys the process of obtaining shrimp meat." It's like someone likes fishing, so isn't it good to go straight to the market and buy fish? Wasting all this money to prepare a fishing rod and spending a lot of time fishing, that's the enjoyment process. ”

"I didn't understand it, but I think you have a point." I nodded solemnly, and then smiled: "It's still delicious lamb skewers." ”

We chatted while eating, and we were very happy, but people like us have an occupational disease, that is, three sentences do not leave the old business, we chatted and chatted, and unconsciously talked about the topic of the current case.

"I absolutely don't believe it was an accidental death." I said lightly.

Li Meng nodded and echoed seriously: "That's right, Du Tan and Xu Kuan's deaths seem to be accidents, but we still found clues." Hu Yuanling's death must not be an accident, but we haven't found the clues yet. ”

"As long as it is done by people, it will definitely leave traces, this murderer is not simple." Ren Qiushi muttered, and suddenly asked me, "But how did the murderer lower Hu Yuanling's blood pressure?" ”

"After our investigation, Hu Yuanling's social interaction is very simple, she commutes to and from work on time, cooks and eats by herself, how did the murderer approach her?" I frowned, puzzled.

"A person's blood pressure will never suddenly drop to a dangerous value without a major illness, if the blood pressure is slowly lowered within a period of time, then Hu Yuanling will definitely be aware of it." Ren Qiushi replied.

Li Meng changed her gloves and continued to peel crayfish, she was also very puzzled by this, and muttered casually: "Will she take blood pressure medicine?" ”

At this moment, Ren Qiushi and I were stunned.

"How can Hu Yuanling have blood pressure medication at home, and she doesn't have high blood pressure." Ren Qiushi replied subconsciously.

Li Meng put a shrimp meat into his mouth, and muttered casually: "The medicine has been changed." ”

At this moment, Ren Qiushi and I were both petrified.

Although Li Meng's explanation seems very reasonable, there are still big loopholes in it.

"The effect of antihypertensive drugs is not so good, and taking it will not immediately lower blood pressure below dangerous values. And blood pressure medication needs to be taken for a long time, and Hu Yuanling is not sick, how can she take medicine for a long time? And how did the murderer change the medicine for Hu Yuanling? As long as the murderer enters Hu Yuanling's home, he will definitely be found by the technical team investigating the scene, but the technical team has found nothing. I pondered for a moment and said lightly.

Li Meng paused, frowned and thought about it carefully, it was indeed an unlikely thing.

Ren Qiushi slowly put down the skewer in his hand and said in a deep voice: "If Hu Yuanling really died because of the sudden drop in blood pressure caused by taking medication, then it will definitely be detected in her blood and stomach solution, whether this is the case, just wait for the results of the laboratory department." ”

"Oh, we're really, working day and night every day, and finally come out for a meal, and we have to talk about work, let's have a meal, don't talk about work, let the brain rest and rest." I raised my glass and said to everyone earnestly.

"That's it, cheers!" Li Meng smiled and raised his glass.

"Cheers!"

The three glasses collided again.

After eating and drinking, Li Meng took a taxi home and went to sleep, her parents lived locally, and she rarely lived in the police dormitory. This is also a large part of the reason why the boss Shen Ruoshan was able to dig her from the provincial bureau, who doesn't want to work and live closer to their parents?

Ren Qiushi and I finished eating, strolling along the street to the bureau, it seems that we have no plans to go home to sleep today, we are all the same, after going home, we are all alone, it doesn't matter where we live.

Halfway through, Ren Qiushi received a message from the laboratory department that Hu Yuanling's biological sample test report came out.

Ren Qiushi glanced at me, no need for him to speak, we have worked together for many years and have made us have a full tacit understanding, I immediately guessed that the laboratory department was careful.

We glanced at each other and quickened our pace.

Back at the Municipal Public Security Bureau, we walked directly to the laboratory department, and there was an eldest sister sitting in the office, her surname was Li, who was a teenager older than us and a mother of two children. It seems that the police are not easy to be a police officer, as long as there is a case, overtime is a common thing.

"Section Chief, the inspection report is out." Sister Li smiled and handed the inspection report to Ren Qiushi.

"Sister Li, it's hard work." Ren Qiushi said with a smile.

"It's not hard, it's you who are hard, I can go home from work now, it's time for you to work overtime." After Sister Li finished speaking, she changed into her clothes and prepared to get off work.

Ren Qiushi and I left the laboratory department and walked to the criminal police team, he looked at the test report in his hand as he walked, and fell into deep thought.

After a while, he handed me the inspection report, looking very nervous.

With this test report in my hand, I can only understand it generally, because there are many terms on it, and there are some symbols and words, although I can't understand it, but I can still see some drug ingredients from the words on it.

After being silent for a long time, Ren Qiushi suddenly said: "Hu Yuanling really overdosed on blood pressure medication......
