"Corrosive ......" Su Ping leaned over and asked, "What is that salt spray, is it difficult to configure?" ”

"It's very difficult to meet the laboratory conditions." Chai Ningning said: "After all, in the laboratory, there are many variables to be controlled, and the results are meaningful. However, if you just want to quickly carrion the iron rope, it is actually quite easy, there is no difficulty, and the raw materials can be easily obtained. ”

"In other words, it's hard to check?" Xun Mu pursed his lips lightly, feeling a little tricky.

"It's really hard to check, and if all the evidence is processed, it's even more difficult." Chai Ningning said again: "I hope that the map detective can find something over there, and I also suggest that you ask when you visit, if anyone has sprayed anything on the steel cable." ”

"Team Su," at this time, Brother Song came over and said, "That copper salt accelerates the acetate spray test, I know." ”

As he spoke, he opened his notebook, read out the name, and said: "During the afternoon visit, a safety officer mentioned that when they buy building materials such as steel bars, they will do this experiment to see the corrosion resistance of steel bars or something." ”

"Huh?" Chai Ningning, who was on the other end of the phone, heard this and was a little puzzled: "They, do this experiment?" You're not mistaken, right? What are they doing with this?

It's not that I hacked them, these current real estate developers are already quite conscientious if they don't cut corners to make a tofu scum project, and they deliberately engage in corrosion resistance experiments? How is that possible? ”

"Oh?" Su Ping immediately gave Brother Song a look, asked him to write down this clue, and then asked: "You mean, no construction team will deliberately do the copper salt accelerated acetate spray test?" ”

"My husband and his uncle are engaged in the construction team, and I also have a certain understanding of this aspect." Chai Ningning said, but his tone was not very sure: "It's just that logically speaking, it's impossible."

As a construction team, their job is not to test the toughness and corrosion resistance of materials, but simply to select the right materials and build them according to the design.

Perhaps some epoch-making landmark buildings or key projects need to consider these, but generally speaking, it is only necessary to ensure that no corners are cut and that the construction work is completed according to quality and quantity. ”

"Then let's go back and find out, confirm and confirm." Su Ping said, and then glanced at Lao Hai, obviously telling him about this.

Seeing that Lao Hai nodded in response, Su Ping asked again: "In addition, are there any other discoveries?" ”

"Not yet." Chai Ningning said: "But this clue alone - the steel rope has been eroded by someone with chemical reagents - can prove that this case is not accidental, but man-made." ”

"We've been sure about that for a long time." Xun Mu raised the mobile phone a little higher and said, "Since the work is done, rest early, work hard, raise the baby with peace of mind, and leave the rest to us." ”

"Okay, then I'll get off work first."

"Well, let's go back quickly, hang up."

Hung up the phone and put the phone back in his pocket, Xun Mu grabbed two more reports from Su Ping's hand and looked at them, roughly flipped through them, and then put the list in charge of this building on the top and said, "Focus on checking this list."

In addition, if you want to spray the salt spray on the steel cable, the amount of salt spray required is estimated to be not small, and it is unlikely that you will be able to hide it from everyone, so ask carefully. ”

Seeing everyone nodding, he said again: "Lao Hai, your task has just been given to you by Lao Su, find out when this construction site began to use this salt spray to test the corrosion resistance of building materials, and why did you suddenly think of testing the corrosion resistance."

Also, whether this thing is used in a large area of the building, or just by the team in charge of the building, or by the construction team directly under the name of Anhe Group, this is very important, and it is important to understand. ”

"Okay." Lao Hai nodded.

Xun Mu looked at Wang Zhao again: "Xiao Wang, no matter what, the existence of this salt spray on the construction site is currently an objective fact, you go and check, has anyone called this thing recently." ”

"Okay."

"Xiao Song, Xiao Qi, Xiao Fang, a few of you, continue to visit and investigate, and gather here in two hours to have a small meeting. That's it, let's all go to work. ”

"Yes!"

After a few people dispersed, Qi Yuan followed Brother Song, and while walking, he said with emotion: "Why do you suddenly feel that I haven't listened to Team Xun for a long time, this feeling is a little nostalgic." ”

"Team Xun has been busy lately." Brother Song chuckled and said: "I heard that next year, there is a deputy bureau to retire, and another is transferred to other positions in the provincial department, and the city bureau will vacate two deputy bureaus at once."

The director asked the Xun team to fight for it and become a deputy bureau in charge of criminal investigation, economic investigation and detention, and detention center. ”

"Huh?" Qi Yuan opened his mouth, a little stunned: "Team Xun is leaving?" ”

"What do you think, of course, I will continue to serve as the leader of our detachment, and I usually sit in the detachment." Brother Song said: "Criminal investigation is very important in public security work, and the Xun team has been promoted to deputy bureau, and our detachment usually has more power to speak.

And this position is basically high-matched, you look at the public security detachment, the traffic management bureau and the traffic police detachment, and the special police detachment, the bosses of these important task forces are all deputy bureaus, our old captains are also, and the bosses of the criminal investigation in neighboring cities are also, just the Xun team is not, how embarrassing. ”

Qi Yuan blinked and didn't ask much.

But Brother Song saw that he was curious, so he said: "The reason is also simple, young, too young, but the ability is strong, the captain is either him or the Su team, the Su team knows that he has offended a lot of people, don't do it, so as not to affect the whole team, so he pushed the Xun team, but the Xun team should have come to this point back then, no matter how high it is, it is too exaggerated."

It's different now, firstly, there is a vacancy in the pit, secondly, the Xun team has been a police officer for 18 years, and he has been a detachment leader for many years. ”

Qi Yuan nodded lightly.

……

At the same time, Xun Mu dialed the phone number of the Graphic Investigation Department again, then turned on the amplification, handed the phone to Su Ping, and then opened the notebook.

The call was answered quickly.

"Team Xun."

"It's me." Su Ping opened his mouth: "Lao Xun is next to me." How about it, have you gone through all the surveillance videos that have been transferred back? ”

"Almost." Lao Xu, director of the Graphic Investigation Section, immediately replied: "However, the monitoring density of the construction site is not very large, and the monitoring quality is quite poor. ”

"Oh? Didn't find anything? ”

"Not really." Lao Xu thought about it, changed his words again, and said: "If you have to say it, the safety officer named Wang Qianghua behaved a little strangely, always leaning towards the construction site intentionally or unintentionally, but after nine o'clock, he hid far away, and his expression and movements looked a little cautious." ”

"Oh?"
