Regarding Wei Yi's conjecture of placing a fourth poison in the ventilation duct, Xu Zheng and Zhang Yuqi agreed very much.

Peng Yue couldn't wait to urge everyone, "Then what else are we going to have?" Let's go directly to the eucalyptus site and determine the type of poison first. ”

Zhuang Qiang also stood up and waved his hand, "That is, if it is determined that it is the air outlet of the central air conditioner, you can start from here, maybe you will find the murderer as soon as you check the monitoring a few days before the incident." ”

】

Xu Zheng and Lang Shaobai also have this meaning, maybe it is really like Zhuang Qiang said, there are clues when you check it.

It's just that Zhang Yuqi pressed down with both hands, but didn't give a direct order, "Don't go anywhere if you stay here, and don't plan to call, I'll go out." ”

After she finished speaking, she left here without looking back, leaving everyone looking at each other, Xu Zheng's heart moved, and said jokingly: "Brother Lang, there have been many people who have invited you to dinner in the past two days, right?" ”

"Well, don't say it, there are all kinds of people looking for me, even one of my former university teachers called, ho... The energy behind it is not small. Lang Shaobai took out his mobile phone and put it on the desktop, his intention was self-evident.

Then Xu Zheng smiled and put the phone on the table.

People who can enter the criminal police detachment are not fools, and now the second brigade is in charge of Su Guangquan's eucalyptus, some people hope that the police will break the eucalyptus as soon as possible, some people hope that the police will suspend the handling of the eucalyptus, and of course some people do not want the police to handle the eucalyptus.

When Zhuang Qiang took out his mobile phone, he also sighed, "Yesterday, my old colleague suddenly asked me to dinner, at this point in time, who of us who are police officers doesn't know what the second brigade is busiest right now." ”

Ji Meiyue smiled bitterly, "Our second team estimates that only Team Zhang and no one dares to look for her to go through the back door, what about you, is someone looking for you to inquire about Su Guangquan's eucalyptus?" ”

"No, I go home from work now, I basically don't have any extra energy to socialize, and I don't want to move when I get home." Li Wanwan began to investigate Su Guangquan's eucalyptus as the second team began to investigate, her work increased exponentially, if it wasn't for Ji Meiyue to help her share some, her overtime would have to be extended by another hour.

Wei Yi put the phone on the table and groped the back of the phone with his hand, "There are so many of us front-line investigators, so it is estimated that there are more people looking for leaders, whether this eucalyptus is fast or slow, after all, it depends on the meaning of the above." ”

Xu Zheng tapped the desktop with his finger, "There is no difference between the speed of the eucalyptus' progress and the speed of the eucalyptus, the big deal is that after collecting clues, we can just find the murderer and not catch it, just to touch the fish." ”

There are only 7 people in the second brigade including the captain, and Li Wanwan is not a formal scout now, unlike the first brigade, they are also divided into two squadrons, but there are five or six people in one squadron.

Therefore, the second brigade can only do its best to complete a eucalyptus, and no matter how much it is, it will be too busy.

At the beginning, the focus of the establishment of the second brigade of the municipal bureau was to focus on the old eucalyptus, but after half a year of establishment, two old eucalyptus were completed, but on the whole, the total number of eucalyptus completed by the second brigade was not much less than that of the first brigade.

Basically, one eucalyptus will not last more than a month.

This also led to the fact that the second brigade didn't even have the time to fish during work, either looking for clues or on the way to catch the suspect.

After more than ten minutes, Zhang Yuqi appeared at the door of the research and judgment room and waved his hand, "Go, set off immediately, remember the principle of confidentiality." ”

It was only when everyone went downstairs that they knew that Zhang Yuqi did not bring anyone from the scene of the eucalyptus scene this time, but she borrowed tools from the technical investigation team, which means that the second team will personally investigate the scene of the eucalyptus scene today.

Fortunately, Xu Zheng is a professional survey technician.

Seven people and two cars went straight to Wanda Plaza in Yiqiao District, and Li Wanwan stayed at home to sort out the materials.

On the way, Zhang Yuqi didn't notify the Liulihe Police Station, but she said to Xu Zheng: "You call your master Anru and ask her to go to Wanda Plaza alone first, and then meet up when you get there." ”

"Team Zhang, there's no need to keep it so strictly secret, the eucalyptus has happened for six days, even if the murderer can't destroy the eucalyptus scene, but these days have passed, it's hard to say whether there are traces or not." Ji Meiyue used her mobile phone to connect the surveillance camera installed by the second brigade at the eucalyptus scene, but unfortunately no one was found sneaking in.

No one sneaked in, there were only two reasons, one was that the murderer did not leave obvious traces when he committed the crime, and the other was that Wei Yi's conjecture was wrong.

Zhang Yuqi sighed, "This eucalyptus seems simple, but the murderer's ability to buy 9 hydroxydopamine neurotoxin abroad has already attracted the attention of the ministry, but unfortunately, the foreign side has not yet investigated who bought this toxin."

The entry and exit administration department also found no traces of toxin inflow.

Now some leaders above are worried that the murderer will still do eucalyptus, and ask us to break the eucalyptus as soon as possible. ”

"Later, if we find traces of eucalyptus at the eucalyptus site, then we can follow this line to investigate. By the way, Team Zhang, before Xiao Zheng hypothesized that the murderer used the technique of flying needles to inject toxins into milkshakes and sour plum juice, did you reflect it to Team Wan? Ji Meiyue asked curiously.

Zhang Yuqi opened her mobile phone and took a look, there was no new news from the Wan Detachment on it, she shook her head, "I must have told him about this, but the plastic cup containing the milkshake and sour plum juice is currently in the laboratory department of the Ministry of Public Security."

In that place, even if our director calls them personally, the news will not be reported quickly. ”

Xu Zheng smiled, "This is not a problem, let's assume that there are tiny needle holes in those two cups or that the murderer used a very small thing to inject venom, then go back and let the Graphic Investigation Detachment study the video of Su Guangquan buying milkshakes and sour plum juice on the way." ”

Because Xu Zheng guessed that it was an extremely small thing, the kind that could not be seen by the naked eye, so even if he looked at this video on the computer, he didn't find it, so he could only use special equipment to process this video, and at the same time, he had to magnify the picture 50-100 times, so that it was possible to see if there was something Xu Zheng guessed.

"yes." Zhang Yuqi also reacted, "You assume first, and then let the map detective operate over there, I think it will definitely work, when I reported to the Wan detachment and the director, I actually forgot about it." ”

Zhang Yuqi shook her head with a wry smile, as for why she couldn't think of this, the main reason was that she had been worried that the leaders at the top would not agree to continue to investigate this eucalyptus.

She didn't tell Xu Zheng that the attitude of the leaders at the top level towards this eucalyptus is unclear, mainly on the government's side, and hopes that the Changming police can cooperate with the promotion of the film's distribution company, the publicity company, so that the popularity of the movie will continue unabated, and the box office will continue to rise, which will far outweigh the disadvantages for those of them.

In the past, people thought that a homicide did not mean that the murderer had been detected, and this would not be the end until the court determined the murderer's crime.

So a eucalyptus comes down, and it has to have six months instead of a year.

Six months!

Six months later, no one will pay attention to this eucalyptus.

Even if there were, there wouldn't be too many people.

Therefore, the film publicity and distribution company has a new idea, that is, to first turn the eucalyptus into a homicide eucalyptus and announce it, triggering a new heat in this news point.

Besides, it has only been six days since Su Guangquan's eucalyptus, and it is understandable that the police cannot find the real culprit.

Therefore, if according to the government's statement, the speed of the second team's investigation of eucalyptus is a little slower, it is best to have results after three days, and in these three days, Zhang Guoshi's film publicity and distribution company will claim to the outside world that Su Guangquan did not die suddenly, but was killed by someone.

As for the murderer, the police have not yet confirmed, and it is suspected that there may be something wrong with the peach shake that Su Guangquan drank last before his death.

The propaganda department of Changming City and even Pingjiang Province recognized the film publicity and distribution company's Wen Huan, and the attitude of the provincial department was a bit ambiguous, but on the side of the Changming Municipal Bureau, the two directors of Li Nie and the Wan detachment were opposed.

The main reason is that there is something wrong with the last sentence of this announcement article, according to this article, it directly puts Michelle Bingcheng and the big star Zhao Jinmai on the cusp.

There is also the fact that the first brigade of the city bureau that investigated this eucalyptus was not capable enough.

Of course, the city bureau does not agree with this document.

In three days, this news will form an established fact in the minds of netizens, even if three days later, the Changming City Police announced the true situation of Eucalyptus, the losses caused to Mixue Bingcheng and Zhao Jinmai are irreparable.

Zhang Yuqi is now the captain of the second brigade of the Changming Municipal Bureau, and for her own honor, she doesn't want the film publicity company to release such news, doesn't this seem to be the incompetence of the police?

The common people don't know how to do the process, and most of the netizens are also cloudy, but there are a lot of people who know how to do it.

Therefore, the two directors of Li Nie resolutely oppose it.

But after all, the Municipal Public Security Bureau is under the dual leadership of the government and the provincial department, so the investigation of this eucalyptus is not whether the murderer can be found immediately, but the game of all parties.

As for Zhao Jinmai and Fan Huihui taking the initiative to give Xu Zheng benefits in the morning, it shows that they are very eager to cooperate with the Changming City police.

If Xu Zheng can take the initiative to reveal a little in the morning, or discuss, or coerce, or cooperate with each other, perhaps, Zhao Jinmai may invite him to dinner.

Of course, Zhang Yuqi knows the ins and outs of these things, and can see the motives of Zhao Jinmai and Fan Huihui, but Xu Zheng at that time didn't understand the true meaning of the beauty because of poor information, which was really funny.

Ji Meiyue looked at her captain, who was her private best friend, talking and talking, she was stunned, but now she was good, and laughed inexplicably.

She secretly stretched out her right hand and pinched Zhang Yuqi, "Team Zhang, don't you call the Wan detachment and ask him to tell the map reconnaissance detachment?" ”

Zhang Yuqi came back to his senses, looked at Xu Zheng who was driving in front of him, and Ji Meiyue next to him, these low-level scouts knew that they were buried in the investigation and didn't care about the difficulties of the leader at all.

If there are no clues, forget it, with clues, will the Nie Bureau and the Wan Detachment support or not?

Fortunately, these leaders of the city bureau are relatively strong, and they have the instructions of the elders of the Ministry of Public Security to "seek truth from facts", and they can check the eucalyptus as they should.

"I thought about it, and after a while, I personally called Qi Haibing, the deputy detachment of the graphic reconnaissance, and asked him to help find a few new colleagues to help us check." Zhang Yuqi finally decided to come forward and contact the detective herself.

You can't push everything on the leader.

Now she has also figured out that as long as she detects the eucalyptus herself, it is useless for the leaders at the top level to play the "procrastination trick" again.

Xu Zheng glanced at Zhang Yuqi through the rearview mirror a little puzzled, "Can you do this?" ”

"Ho... What do you mean, what can the 10,000 detachment still find me? Zhang Yuqi glanced at him, "I'm not going to cut it first, but to try it with a different way of thinking, after all, our own conjecture needs us to find a way to prove it." ”

Ji Meiyue also nodded in support, "If we break the eucalyptus in two days and lock up the murderer, then what do you say, how will Zhao Jinmai thank us?" What about you, Xu Zheng? ”

"You shouldn't ask me, you should ask Brother Qiang and Peng Yue, you two must want Zhao Jinmai to make a personal promise, otherwise you use the walkie-talkie to ask them." Xu Zheng is not ignorant of customs at all, this morning's abnormality of Zhao Jinmai and Fan Huihui, if he were Zhuang Qiang, he would definitely think more.

It's a pity that Xu Zheng didn't have any thoughts about the two of them.

While speaking, everyone rushed to the parking lot of Wanda Plaza, and when they got out of the car, the high temperature at about three o'clock in the afternoon directly made people feel like they were in a pot of boiling water.

Everyone got out of the car without delaying for a second, and walked directly into the mall, it was still cool here, Xu Zheng looked around the first floor of Wanda, probably because of the summer vacation, there were a lot of people, and most of them were girls.

One is cooler than the other, with short sleeves and small hot pants, and a pair of long legs wearing small slippers, which is very dazzling.

It's a pity that Xu Zheng, as a policeman, really didn't dare to stare at these female college students in this scene full of cameras.

Rushed to the Wanda Cinema on the second floor, Anru sat alone in a corner of the waiting hall, she was fat and old, sitting with these teenagers and girls, very conspicuous, and when she saw Xu Zheng and them arrive, she was relieved.

"Master, what are you doing sitting here, like a mother who catches her child's early love." Xu Zheng walked to Anjou's side and teased her, although Anjou is vigorous and resolute in her work, but in her daughter and son, she is a complete cat mother.

Feng Tingting and her younger brother are not afraid of Anjou at all, no, she is 17 years old this year, Anru began to worry about her early love, she wanted to watch a movie without anyone to accompany her, and Xu Zheng used to take her here to watch a movie when she was resting.

But now Xu Zheng doesn't have time for himself.

Anru and Zhang Yuqi said hello, and then scolded Xu Zheng with a smile: "You stinky boy, I told Tingting the day before yesterday that she Miss Xu, no, she has been yelling at me every day for the past two days to send her to your house, I see, she just wants to go out to play." ”

"Haha, if the master is not like this, Tingting wants to go to me and ask Sister Xiaoxin to pick her up, or she will take a taxi herself, she is so old, you still let her go to cram school during the summer vacation."

While Xu Zheng and Anru were talking, everyone walked to the No. 2 screening hall, and as the door lock opened, Manager Chu of Wanda Cinema who followed him was about to turn on the central air conditioner.

Zhuang Qiang hurriedly grabbed him, "Manager Chu, let's not turn on the air conditioner today, we want to do a test inside, by the way, can you help us find a telescopic ladder, let's use it." ”

Manager Chu looked at Zhuang Qiang a little puzzled, if the air conditioner is not turned on on on such a hot day, even if the second hall is a little cooler, it will make people sweat after staying for a while.

Anru came over and whispered a few words to him, Manager Chu nodded, didn't ask anything more and turned around and walked out, after a while, he personally carried a telescopic ladder and walked over, put it down, and asked someone to send a bag of mineral water from Nongfu Spring before leaving.

"Brigade Zhang, if there are no other arrangements, shall I wait for you outside the door, or shall I go back first?" Anjou saw that the Second Brigade was about to look at the ceiling of Hall 2 and realized what clues they might have found, so he took his leave.

Zhang Yuqi thought about it, this eucalyptus is still not easy to involve too much, but there are still some things that need An Ru to help here, "Director An, can you wait for us outside for a while, and do us a favor by the way, if someone wants to come over, no matter what he does."

You just need to keep an eye on it for us. ”

This time, all the members of the second team rushed here, maybe at this time, those who paid attention to this eucalyptus had already gotten the news, and even the murderer might know.

At this time, no one can say whether he will come to Wanda Cinema.

Of course Anru didn't know this, she came over today to cooperate with Zhang Yuqi's actions, she walked out of the second hall, helped close the door, thought about it, and sat back in the position just now.

When Anru left, Zhuang Qiang and the others hurriedly stretched out the ladder, and then Xu Zheng took the equipment from the current survey and waited for the ladder to climb to the air conditioning outlet.

Because this hall has nearly 1,000 square meters, a total of 161 seats, and four air outlets, of which the air outlet in the front left is facing the position where Su Guangquan was sitting, and the second seat in the front left row.

So the biggest possibility that the murderer placed the poison is here.

Sure enough, when Xu Zheng climbed up, the screws of this air outlet did look like they had just been loosened, because this was the ceiling, and there would always be a little dust on it over time, but these four screws obviously had traces of being rubbed.

Xu Zheng was wearing gloves, a mask, a hood, and a tool kit, and after a while, he removed the four screws, and then handed the plastic plate down, "This thing may have fingerprints on it, you wear gloves when you pick it up." ”

"Xu Zheng, do you mean that someone has moved this air outlet?" Peng Yue immediately asked excitedly.

"Well, I look like it, you wait a minute, I'll take a closer look inside, and I haven't found any traces of the toxin yet." Xu Zheng leaned his neck a little uncomfortably, the air conditioning vent was pitch black, and he could only find a flashlight from his toolkit.
