Ma Liang thought for a while.

"When we arrived at the theater, the concert was not over yet. We were taken to the backstage by security. A person in charge received me and asked me several times, did Xu Qingquan do something?

I said that we cannot disclose the details of the case, but at present, the deceased is only related to Xu Qingquan, and is considered his girlfriend. I want to find him and go back for a test to rule out suspicion.

Hearing what I said, he didn't seem so nervous at first, and then nodded and walked out. When the door was closed, I heard him shouting in the intercom, let the cello substitute come on, don't make any more mistakes in the last song, replace Xu Qingquan

Stand down, someone is looking for him.

I think this is a bad performance. We waited for a long time and they went to look for it. Only then did they find that Xu Qingquan was chatting with someone and told us our identities. Only then did Xu Qingquan remember this matter. He said

I forgot about it and just thought about the performance.

He said that he had been nervous recently, had lost his hair and had severe headaches, and his memory was not very good. He took painkillers in front of us, I think it was Fenbit, and then asked us why we were looking for him. We said

After hearing the intention of coming, he was not irritable or resistant.

I was just very surprised, and asked carefully about the process of Li Li's accident. There was no grief like losing a loved one, it was like knowing that an acquaintance had an accident, and then feeling a little sad, that's all. After that, we went to the provincial department to take samples.

Waiting for the results to come out, I quickly drove back with him. Xu Qingquan sat in the middle of the back seat, I sat on the left side of the back seat, and he sat on the right side. There was not much embarrassment all the way, but when something happened, it was instantaneous.

thing.

I was a little dazed in my sleep, and I felt the lights were dazzling. As soon as I opened my eyes, the car started spinning. I could only try my best to press Xu Qingquan's head and hands under my armpits, and then I didn't know anything."

It seemed that Zhou Ning was recording, and a rustling sound came from the speaker.

"He said he had headaches, hair loss, memory loss, and mental stress, right?"

"Yes, okay, give Lao He the phone number. I'm done asking. You guys take good care of yourself and don't be in a hurry to leave the hospital. We'll see you after these busy days."

Ma Liang was a little embarrassed and quickly waved his hand and handed the phone to He Shancun.

"Director Zhou, don't be so polite. If we hadn't been careless, we wouldn't have caused such a big mess. You guys should be busy with your cases. I know how busy you are these days. Let's chat."

He Shancun took the phone, turned off the speaker, waved to several people, walked out of the ward quickly, walked to the safe passage, and then asked in a low voice.

"Tell me, what else do you have to explain?"

"Haha, aren't you also very interested? Apart from blood tests, how can you tell whether it is vitamin A poisoning?"

"Wouldn't it be better if I asked this earlier? Do a lumbar puncture and check the cerebrospinal fluid pressure. This is the most intuitive test. His hair loss, headache, memory loss, and mental stress are indeed like vitamin A poisoning. But if you have had similar cases before

, it is naturally easier to judge, but I think doing a lumbar puncture is the fastest.”

Zhou Ning exhaled and suddenly felt confident.

"Then do it. You said this method is not suitable for our autopsy. Tell me the results after the examination. With this test, I want to see the concentration of various substances in it, especially impurities. If these are the same, then it may be the same person.

Poison."

He Shancun hummed twice.

"Okay, Gungun, let me call you and arrange work for me. Every day, you are either hospitalized or a colleague has a car accident. If I don't have to be your Baidu, I'm really annoyed."

Zhou Ning hung up the phone and rubbed his nose, while Liu Yongxin laughed at the side.

"Lao He's attitude is pretty good. Although he says rude words, he won't delay you for anything. But according to what he said, identification can be made by doing a lumbar puncture, so the speed of judgment is also faster.

can be improved.”

Zhou Ning nodded.

"I'll have someone go downstairs to wait for the blood sample. I'll tell Sister Cui again. I think she will be interested. After all, the more samples there are, the easier it is to find problems."

Liu Yongxin sat on the sofa and crossed his legs.

"Don't be so sad. It's useless to worry now. First, the test will have to wait; second, Peng Shinian can't ask about the progress; third, it will take time to investigate Zhang Fangfang and Liu Meiling. Don't be impatient.

!”

Zhou Ning stood up and looked out the window. He knew he was impatient and sighed.

"I know I'm impatient, but Master, I always have a feeling that Li Li, Zhang Fangfang, and Liu Meiling must have some secrets. After all, the drama of three classmates dealing with a man is so uncommon that most people can't accept it.

, but they seem to still enjoy it."

Of course, Zhou Ning still has a doubt that lingers in Zhou Ning's mind.

But there is no evidence to support it, and it is not convenient to talk about it. Just like the headless serial murder case in Hai'an City that happened nineteen years ago, Zhou Ning always feels that there may be some past between these three people and Xu Qingquan.

, but they haven’t found it yet.

September 4, 2013

Early in the morning, outside the laboratory door.

Zhou Ning crossed his arms and looked at the access control at the door of the laboratory.

"He hasn't come out these days?"

Da Zhao nodded.

"There is a sticky note on the door, which says just leave three meals at the door and don't knock. The access control has been reset by him, and the ditty has not been opened. If there were no toilets and bathrooms in the laboratory, I would have

Someone came over to demolish it, and every day there was trash from the previous day at the door, but it’s been three days, should we go in or not?”

People who engage in research are persistent, and Zhou Ning knows it very well. Don't look at Xiaoqu and it is very suitable for their work, but it was not like this at school. When you talk to him, you will only reply a few words if you like it or if you are interested.

Treat you like air.

But this guy has been in seclusion for three days, and he is really worried. He has not come up with any results on other things, and is driving him crazy. This is not worth the gain, and there is no way to explain it to Li Chengbin.

When Zhou Ning raised his hand and was about to say something, the door was opened and Peng Shinian stood at the door with unshaven beard.

He swiped his access card and heard a beeping sound. Peng Shinian put his hair back and said:

"Okay, the access control has returned to normal, you can come in."

Xiaoqu pushed aside the people in front of him, squeezed to the front, looked at the door control and Peng Shinian, with surprise and confusion on his face.

"How did you do it? I didn't even unlock it. What did you set?"

Peng Shinian smiled, and several wrinkles appeared on his dirty face.

"It turned out that when I was in the laboratory, I learned from their R&D programmers to set my card as the main card. Whenever I swipe the card in reverse, nothing can be opened here, not even the people who designed the software can do it because of the password.

Set to scroll."

Da Zhao waved his hand and pushed Xiao Qu away.

"I said, poet, are you in seclusion? The door is closed and we are not allowed in. It is like stealing a mine. What did you do?"

Just as Peng Shinian was about to speak, he glanced at Zhou Ning, and then smelled it on himself. The smell almost sent him away, and he couldn't help but retched.

"I'm going to take a shower and change clothes. You guys come in first. I'll tell you in detail later."

A bunch of people looked at each other and quickly entered the laboratory without any nonsense.

Da Zhao glanced at the room, covered his mouth and nose, called Sun Gaotie, and quickly opened all the windows in the laboratory. Of course, the door here was also opened, and the ventilation took a while to dissipate the smell.

Ten minutes later, Peng Shinian came out, shaved, and although his hair was wet, he looked much normal. Seeing Zhou Ning looking at him, Peng Shinian felt a little embarrassed and hurriedly ran to Zhou Ning.

Holding the remote control, I turned on the display screen, and several pictures were continuously displayed on it. It looked like there was a little orange trace in the black background.

Although I don't know what it is, I let Peng Shinian study it for three days, and it seems that he has discovered it.

"In the past two days, I have compared many things. The thing that interests me the most is this thing. It was found in the gap between Xu Qingquan's shoes, and in the gap between the wheels of his trolley case, and on the outside of the cake box.

, these particles or pollen were also found.

After detailed analysis and comparison of various ingredients, I found that this is a very distinctive plant in Qindao, called Qindao copper hammer grass. It is an annual herb of the genus Hyssop in the family Asteraceae, with flowers

The tongue is white, and the largest yellow part in the middle is the stamen.

After the flowers fade, the stamens will be preserved until the whole plant withers. This plant likes light, is drought-tolerant, and is indifferent to soil, but is extremely afraid of water. It often grows on sunny slopes without shrubs. Most of the mountains around Qindao are stone mountains.

, the root system of this plant is not very developed and cannot grow.

Therefore, their distribution areas are very limited, mostly on low hillsides, in places with plenty of sunshine and less human activities. Their blades are sharp and serrated, and they can cut people if not careful, so the distribution range I give is,

It’s less than the area on this picture.”

Da Zhao coughed, and he finally understood. Peng Shinian already had an idea, but it was related to the subject he studied. He always wanted to demonstrate something, so he didn't have the time now.

"Don't talk about theories, just talk about the results and where do you think they will appear."

Peng Shinian pursed his lips, and seeing Zhou Ning looking at him, he quickly said:

"According to the growth season of Qindao Brassica, it will bloom between May and September. I think a cemetery is most suitable for a place with little human traffic, a gentle slope with soft soil, and a sunny location with little water."

Da Zhao thought for a while, took out his cell phone and glanced at the lunar date on it.

"August 21st is the Ghost Festival. We Qindao people usually go to worship on the 14th or 15th day of the seventh lunar month. Of course, if the time is inconvenient, it is not impossible to advance two days in advance. At this time, we encounter the copper hammer grass

The chances are great, I remember Xu Qingquan’s parents are gone too, right?”

Xiaoqu glanced at Peng Shinian at this time and showed the notebook to Da Zhao and Zhou Ning.

"Last night, the poet asked me to help check. The cemetery of the Xu family's parents is in Jingkou District, and it is an extremely high-end double tomb. Moreover, I checked the surveillance of the Huanwan Expressway and the undersea tunnel, and I did not see the Xu family's siblings.

Traces of several people’s paths.”

Da Zhao's eyes widened.
