The three of them returned to the detachment, just in time for the meal, and when they arrived at the parking lot, Xu Zheng did not follow Zhang Yuqi up, "Team Zhang, Sister Meiyue, you go up to eat first, I won't go to the cafeteria to eat today." ”

Zhang Yuqi thought he was going home or going out to eat, but he didn't think too much, just waved his hand and left.

Xu Zheng stood at the door of the city bureau and waited for a while, Han Xin drove her Q5 over, this car he had registered a license plate at the security office of the city bureau and also applied for a pass, so the car could drive directly to the parking lot of the city bureau.

Now he is a squadron leader, and he also has his exclusive parking space in the parking lot, but the location of his fixed parking space is not very good, but it is much better than others.

Like Ji Miyue, there is none.

In addition to the fixed parking spaces for the leaders, there are also some parking spaces close to the office building, which are not parked by ordinary people, which are prepared for those colleagues or leaders who come to do things outside.

Anyway, under Xu Zheng's command, Han Xin walked around for a while before stopping at his exclusive parking space, "Xiaozheng, your parking space is a little far away from your office building." ”

Han Xin is finally officially on summer vacation, she has nothing to do during the holidays, no, she proposed to send lunch to Xu Zheng when she was a little cooler today.

"Sister Xiaoxin, you don't have a backache when you stand and talk, how can our city bureau compare with your school, how big your place is, I can have a parking space here to make my colleagues envious.

Like Sister Mitsuki, she always parks her car outside, and sometimes she has to walk a kilometer to find a parking space. ”

While the two were talking, they came to the detachment office building, where Xu Zheng worked was not easy for ordinary people to enter, but this definitely did not include Han Xin, with Xu Zheng accompanying him all the way, Han Xin easily followed him to the office.

At this time, everyone had already gone to the cafeteria to eat, and the whole office was coding words in front of her exclusive desk at the door, Xu Zheng took a look, hey, they were recording the transcript they made from Zhao Jinmai on the computer today.

Han Xin smiled after a glance, "Wanwan, why don't you download a converter, your transcription is slow and inaccurate." ”

Li Wanwan saw Han Xin and Xu Zheng at this time, and hurriedly stood up, "Why is Sister Xiaoxin here?" Then she saw the lunch box Xu Zheng was holding in his hand, and her eyes were starry, "Wow, Sister Xiaoxin, did you deliver food to Senior Brother?" I'm so envious, brother, I seem to be a little hungry. ”

Xu Zheng didn't pity the flowers at all, and shook his head directly, "I feel that I should be able to eat at noon today, so you should go to the cafeteria by yourself."

You stupid, you can't even convert formats, how do you do back office? ”

"I'm not studying, Sister Miyue was in a hurry to eat just now, so I wasn't embarrassed to ask." Li Wanwan blushed, in fact, she just checked on the Internet, what kind of applet to use on WeChat, but this is a transcript, she feels that it is a bit inappropriate to take pictures with her own mobile phone...

"Then let Sister Xiaoxin teach you, I'll go to dinner first." Xu Zheng shook his head, so stupid, "Sister Xiaoxin, you teach her, well, this is a transcript, you can't read it, then you can do it..."

Han Xin interrupted him with a smile and pointed to Xu Zheng's desk, "You go to eat, I can save this matter." ”

Yes, leave this matter to the two of them, Xu Zheng hurriedly ran back to his desk, opened the lunch box, and the fragrance of old duck soup spread throughout the office, the rice that Han Xin brought to Xu Zheng was very simple, a simple stir-fry, a small portion of salted duck, a piece of duck soup, and a box of rice.

Han Xin quickly taught Li Wanwan how to extract the text on the photo, and after he was done, he urged Li Wanwan to go out to eat quickly, as for her wanting to rub Xu Zheng's rice, that's really embarrassing, Han Xin brought a little little bit of food today.

This is the second time Han Xin has come to Xu Zheng's office, sitting next to Xu Zheng, "Xiaozheng, next time let's eat directly in the car or in the small cafeteria, I always feel that there is some important secret here, if it is leaked, we will not be able to tell." ”

Xu Zheng thinks about it, although he is now working on the computer to process documents, but handwritten transcripts like today still can't be avoided, "That's okay, I won't come up in the future." ”

"Well, you hurry up and eat, I'll go back when I'm done, and you can also take the time to sleep for a while, by the way, can you get off work early today?"

"It's really hard to say today, I'll fight for it, what, what's the matter?"

Han Xin shook his head, "It's nothing, it's just that Xiaoyi and Yueyue are going to play today, don't Yueyue miss you, I want you to play games with her." ”

"Haha, Xiao Yueyue, I haven't seen her for a long time, so you go back to Xueyuan Road, there is a toy store there, you go buy a bigger Barbie doll and give it to her, but you must say that I gave it to you."

"You, okay, just say you sent it."

While the two were talking, Xu Zheng hurriedly finished eating, and then sent Han Xin down, the whole process was only 15 minutes at most, he wanted Han Xin to stay a little longer, but Han Xin looked at the computers in the office and felt that he was not used to being here.

After sending Han Xin away, Xu Zheng took out the blanket he left in the office, covered his body, and fell asleep directly on the office.

-----------------

At two o'clock in the afternoon, all the members of the second team began to study and judge on time.

First of all, Ji Meiyue briefly talked about this morning's events, and at the same time asked Li Wanwan to transfer the transcripts she had made to the laptops of each member, "At present, Xu Zheng has put forward a conjecture, that is, the murderer's original target was the big star Zhao Jinmai.

But by mistake, the deceased Su Guangquan became a substitute for the dead ghost.

According to the available testimonial evidence, Xu Zheng guessed that the peach shake, sour plum juice, Dior commemorative coral-colored lipstick, and one other thing that has not been determined for the time being, these three things are the best choices for the murderer to poison.

Of course, these are just speculations, and if you want to be sure, you have to wait until the test report of the Ministry of Public Security two days later. ”

As soon as Ji Meiyue's words were finished, the rest of the people discussed, and Peng Yue took the lead in asking Xu Zheng, "This is not right, the milkshake and sour plum juice are all served in plastic cups, how did the murderer poison them?"

Xu Zheng, I went to the scene to see that the milkshake was processed by three employees and three stations of Mixue Bingcheng.

The shop of sour plum juice is packaged directly so that customers can take it themselves.

There is also lipstick, which has always been carried by a big star assistant, how can the murderer unknowingly apply poison to the lipstick? ”

This is indeed a very difficult thing, but Xu Zheng had already come up with a countermeasure when he was eating an old popsicle yesterday afternoon, "Before answering this question, I will show you a demonstration." ”

Xu Zheng opened the briefcase he usually carried, his bag was cut from cowhide on the outside, and there was a hole in the inside, which he specially commissioned someone to hand-build, of course, the price was expensive.

The main thing is that the stuff inside is very useful to him.

I saw Xu Zheng take out an unopened bottle of Coke from his bag and put it three meters away, and then took out a steel needle from the bag, no, it should be said that it was an embroidery needle, he wanted to find a steel needle, but unfortunately this thing was not sold, and the simple embroidery was also acceptable.

"Let me show you what I just learned."

As soon as Xu Zheng's words fell, he pinched the embroidery needle in his right hand and threw it towards the cola three meters away, and the quiet meeting suddenly sounded the sound of his arm shaking, and other than that, there was only the curious inhalation of everyone.

Because it was placed on top of the cola bottle on the other end of the conference room table, you didn't have to look closely to see an embroidery needle stuck in it.

Xu Zheng's current spare time, in addition to practicing flying knives, is to practice flying needles, fortunately, he also has the advanced cold weapon ability given by the system, and it is not difficult to learn these two.

It's just that he performed this mastery, and this time the big guy didn't applaud him, except for Li Wanwan who looked at himself with admiration on his face, everyone else actually pondered.

Peng Yue was still flexible in his thinking and quick to react, "Xu Zheng, do you mean that someone used a flying needle to carry poison and shot directly into the milkshake and sour plum juice that Su Guangquan bought, that... So what's the deal with lipstick? ”

Zhuang Qiang didn't wait for Xu Zheng to answer, so he laughed at Peng Yue, "Are you funny?" Also flying needles, Xu Zhengna means that someone nearby has some kind of weapon that can be poisoned into the cup of milkshake and sour plum juice in the air.

As for what weapon, I guess you're not sure about it, right? ”

Xu Zheng nodded and said to Peng Yue, "Why are you staring at the lipstick?" Lipstick is something that Zhao Jinmai must use, especially at the roadshow scene, she wants to maintain her image, she has used coral pink lipstick in the previous sessions, and this time is definitely no exception.

Is it difficult for a professional killer to sneak in the face of poison on top of lipstick? ”

Peng Yue thought about it, Zhao Jinmai Roadshow had already traveled to six cities, and he was familiar with their life and rest, if he wanted to sneak in while the night was going to sneak in, he seemed to be able to do it himself.

If it's a professional killer, it's easier to do these things, right?

Lang Shaobai now also agrees with Xu Zheng's statement, but there is one thing he hasn't figured out yet, "The previous investigation direction of the first team also believed that Zhao Jinmai was the target of the murderer, but after their investigation at that time, they found that all the things that Zhao Jinmai ate and drank were also used by her assistant, including the same cosmetics, including the water in the bathroom."

There is also Su Guangquan, except for Su Guangquan, who ate an extra original ice cream and sour plum juice than Zhao Jinmai and Fan Huihui, everything else is almost the same.

But if you say that ice cream is poisonous, it can't be justified, because Zhao Jinmai never eats ice cream, and the murderer will not poison ice cream.

Therefore, the first team studied and judged many times, but finally gave up starting with Zhao Jinmai.

Now according to your investigation, the reason why Su Guangquan was poisoned, in addition to sour plum juice and milkshakes, was lipstick, he ate Fan Huihui's lipstick, and Fan Huihui's lipstick was Zhao Jinmai's.

In this way, it can be explained clearly, why Su Guangquan was poisoned, that is, he drank that cup of sour plum juice. ”

Xu Zheng nodded in agreement with his analysis, "At the moment, I just can't figure it out, what is the fourth thing, Su Guangquan and Zhao Jinmai ate or drank the same thing at the same time. ”

At this time, Wei Yi, who was sitting at the tail of the conference table, looked up at the air outlet of the central air conditioner above his head, and suddenly said: "You see, if the murderer puts poison in the air outlet of the air conditioner, will the entire roadshow scene be filled with the fourth poison." ”

Yes, according to the analysis of relevant experts of the Ministry of Public Security, the amount of 9 monohydroxydopamine neurotoxin is enough to make a person die invisibly, so as long as the air contains a fourth poison, it can explain Xu Zheng's conjecture.
