"Corrosion..." Su Ping leaned over and asked, "That salt spray, is it difficult to configure it?"

"It's naturally very difficult to meet the laboratory conditions." Chai Ningning said: "After all, in a laboratory, there are many variables that need to be controlled for the results to be meaningful. But if you just want to quickly carrion iron cables, it is actually quite easy.

There is no difficulty at all, and the raw materials can be easily obtained.”

"In other words, it's not easy to check?" Xun Mu pursed his lips slightly, feeling that something was a bit tricky.

"It's really difficult to investigate. If all the evidence has been disposed of, it will be even more difficult." Chai Ningning said again: "I hope the detective can find something. I also suggest you ask when you visit.

Has anyone sprayed anything on the steel cables?"

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

As he spoke, he opened his notebook, read out the name, and said: "During the afternoon visit, a safety officer mentioned that they would do this experiment when purchasing building materials such as steel bars to see if

The corrosion resistance of steel bars and so on.”

"Huh?" Chai Ningning on the other end of the phone heard this and was a little confused: "Are they doing this experiment? Are you right? Why are they doing this?

It’s not that I’m criticizing them. These real estate developers nowadays are quite conscientious if they don’t cut corners and turn into shoddy projects, but they also deliberately conduct anti-corrosion experiments? How is this possible?”

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

?”

"My husband's uncle is 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 logically speaking, it's impossible.

As a construction team, their responsibility is not to test the toughness and corrosion resistance of materials, but only to select appropriate building materials and build them according to the design.

Maybe some epoch-making landmark buildings or key projects need to consider these things, but generally speaking, you just need to ensure that you don't cut corners and complete the construction work according to quality and quantity."

"Then let's go back and find out more and confirm." Su Ping said, then glanced at Lao Hai, obviously giving him the order.

Seeing Lao Hai nodded in agreement, Su Ping asked again: "Apart from this, are there any other discoveries?"

"No more for the time being." Chai Ningning said: "But just this clue - that the steel cable was corroded by chemical reagents - can prove that this case was not an accident, but man-made."

"We have already determined this." Xun Mu raised the phone a little higher and said, "Now that the work is done, go to bed early. You have worked hard. You can raise your baby with peace of mind. Leave the rest to us."

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

"Well, go back quickly and hang up."

After hanging up the phone and putting the phone back in his pocket, Xun Mu grabbed two more reports from Su Ping and looked at them. He briefly flipped through them and then put the list of people responsible for the building on top and said, "Focus on this."

A list.

In addition, if you want to spray that kind of salt spray on the steel cable, the amount required is probably not small, and it is unlikely that you can hide it from everyone, so ask carefully."

Seeing everyone nodding, he added: "Lao Hai, your task has just been assigned to you by Lao Su. Find out when this construction site started using salt spray to test the corrosion resistance of building materials. Why did you suddenly think of testing it?"

Corrosion resistance.

Also, is this thing used in a large area of ​​​​the building, or is it only used by the team responsible for this building, or is it used by all construction teams directly under the name of Anhe Group? This is very important and must be investigated.

clear."

"Okay." Lao Hai nodded.

Xun Mu looked at Wang Zhao again: "Xiao Wang, in any case, the existence of salt spray on the construction site is now an objective fact. Go check and see if anyone has used this thing recently."

"good."

"Xiaosong, Xiaoqi, Xiaofang, you guys, please continue to visit and investigate. We will gather here in two hours for a small meeting. That's it, let's go to work."

"yes!"

After the people dispersed, Qi Yuan followed Brother Song. As he walked, he said with emotion: "Why do I suddenly feel like I haven't heard Captain Xun give orders for a long time? This feeling makes me a little nostalgic."

"Team Xun has been quite busy recently." Brother Song chuckled and said, "I heard that one deputy bureau will retire next year, and another will be transferred to another position in the provincial department. The municipal bureau will have two deputy bureaus vacant at once.

The director asked Captain Xun to try to become the deputy bureau in charge of criminal investigation, economic investigation, detention, and detention center."

"Ah?" Qi Yuan opened his mouth, a little stunned: "Captain Xun is leaving?"

"What are you thinking about? Of course, I will continue to serve as the captain of our detachment, and I will still be in charge of the detachment on a daily basis." Brother Song said: "Criminal investigation is very important in public security work. Captain Xun has been promoted to deputy bureau, and our detachment has a stronger say in daily life.

.

Moreover, this position is basically highly qualified. If you look at the Public Security Detachment, the Traffic Management Bureau and Traffic Police Detachment, and the Special Police Detachment, the bosses of these important work teams are all deputy bureaus, as are our senior captains, and so are the bosses of the criminal investigation team in the neighboring city.

, Captain Xun is not the only one, how embarrassing."

Qi Yuan blinked and didn't ask any more questions.

But Brother Song saw his curiosity, so he added: "The reason is simple. You are young, too young, but you are also very capable. Either he is the captain or Captain Su. Captain Su knows that he has offended many people, so he will not do it."

, so as not to affect the entire team, I recommend Team Xun, but Team Xun has reached the end of the road at this point. No matter how high the match is, it is too exaggerated.

It's different now. Firstly, there is a vacancy in Keng'er. Secondly, Captain Xun has been in the police for eighteen years and has been a detachment leader for many years. He has the rank of Second Superintendent and has already reached the minimum standard for the rank of Deputy Division. There is still hope."

Qi Yuan nodded lightly.

…

At the same time, Xun Mu dialed the number of the Picture Investigation Division, then turned on the loudspeaker, handed the phone to Su Ping, and then opened his notebook.

The call was answered quickly.

"Team Xun."

"It's me." Su Ping spoke: "Lao Xun is next to me. How about it? Have you checked the surveillance video that was transferred back?"

"That's almost it." Lao Xu, director of the picture detection department, immediately replied: "However, the monitoring density at the construction site is not very high, and the quality of monitoring is also quite poor. So far, no valuable clues have been found."

"Oh? Didn't find anything?"

"Not really." Lao Xu thought for a while, then changed his words and said, "If I have to say something, the safety officer named Wang Qianghua behaved a bit strangely. He always leaned toward the construction site intentionally or unintentionally.

But after nine o'clock, he hid far away, and his expression, demeanor, and movements seemed a bit cautious."
