The administrator explained: "The underwater monitor is different from the water, although it also has the function of screen monitoring, but it is mainly combined with the water quality analyzer to monitor and warn in real time, data processing and analysis of water dissolved oxygen, PH value, temperature, conductivity, salinity, so the number is not much, but if there is a person under the water, it can still be seen." ”

I nodded, "So there's no thief in the video surveillance?"

"Yes, we called back the data and analysed some of the stolen oysters and it showed that no one had ever been close to the cages during the two cleaning checks. ”

It's a bit troublesome, and it can basically be ruled out that it was a big living person who stole the pearl, after all, such a big target, let alone do it, even if it is passing by, it can be used as suspect evidence. I'm worried about whether it's really a youkai doing it.

I asked the administrator, "Can the underwater monitoring equipment monitor the specific cages?"

The Administrator was stunned, "Is this necessary?"

He opened his hands and pointed to the floats on both sides of the causeway, "With so many cages, it is impossible to do such detailed monitoring, and their original purpose is not to prevent theft, but if necessary, it is still possible to temporarily change the position of a few equipment." With that, he looked at Xi Fan.

Xi Fan nodded and asked me, "Brother Li, you see that there are so many cages here, even if we really want to keep an eye on it, then we don't know which one to target?"

I asked the caretaker, "Is there a pattern to the stolen mother-of-pearl cages?"

The administrator shook his head, "There really isn't a specific pattern, and not the entire cage pearl has been stolen. ”

It's still a random crime, how can I get it? I was thinking about Su Er walking up to me and asking me how well I understood, I looked left and right and asked her what about Fengfeng? She said that Min Ziqin was accompanied by picking pearls, saying that she wanted to pick some beautiful ones to take back to Aunt Lin. I repeated the conversation with her.

Su Er lowered her head and thought for a moment, then suddenly asked the administrator, "Are there any records of the stolen oysters?"

The caretaker replied: "Yes, because the position of the oyster in the cage is fixed, so we have to make specific records according to the number and position of the cage. ”

"Check what the stolen pearls are. ”

The administrator hurriedly took out the phone and dialed it, and after a while he was surprised: "The stolen pearls are all high-grade colors that can be harvested, without exception." ”

Sur nodded, "It seems that the thief has a good eye. "I said that it is not natural, whoever steals melons will not pick a ripe hug.

The caretaker replied: "No, it is actually very difficult to observe the color of the pearls underwater, not as easily as we do during the cleaning process. ”

Su Er held his chin and said, "Unless the oysters have opened their shells when the thieves arrive, the thieves can pick them one by one." ”

The administrator laughed and said it was impossible, I thought it was a bit bizarre. Isn't it funny that the thief enters the vault and all the safes are automatically opened for him to choose.

"There's also the possibility that the observation records are leaked, so that the thieves can hit their targets accurately. As soon as these words came out, the administrator's face changed, which is not impossible, and if it is true, then the responsibility is great.

I asked him, "Who has access to these observations?"

The administrator thought for a moment and said: "The specific records rarely need to be proposed, basically for data statistics and analysis, even Mr. Shen, it is only the number and cultivation rate of high-grade pearls in the same period, and she doesn't care about which mother oyster it is." Therefore, except for the people in the data analysis room, there should be no way for others to get the raw data. ”

"Are the people in the data analysis room reliable?"

The administrator was a little embarrassed, looked at Xi Fan and said, "The people in the data analysis room are all personally checked by Mr. Shen, and they should be reliable." ”

The implication of this is that if he wants to investigate the person in the data analysis room, he, the base administrator, is afraid that it will not be easy to do it, unless it is Shen Lingyi who nods. I exchanged opinions with Su Er, and I felt that it was better to feed back this information to Shen Lingyi first, and let her decide the direction of the next investigation, and if it was to investigate people, a female boss like her would definitely be much more experienced than us stunned young people.

I bumped into Feng Feng and the others, saying that they would change places and continue to play, Feng Feng had no opinion, and before dinner, Su Er and I went to Shen Lingyi's office first to feed back the results of our investigation today.

Shen Lingyi was wearing a pair of gold-wire glasses when she was working, she crossed her hands on her chin and thought for a moment, "All the missing are high-grade pearls, without exception, I really didn't pay attention to this information before." In other words, there is likely to be a problem in the data analysis room, either someone has leaked the data of these upper grade oysters, or someone has broken into the data analysis room and stolen the information. ”

Su Er nodded and said, "Otherwise, there should be no way to do such a precise stealing act." ”

Shen Lingyi asked, "Do you have an idea of the identity of the thief?"

I shook my head and said, "None of the monitoring instruments have seen anyone, but the pearl is still missing, which is very telling." ”

"I'm going to take some underwater monitors and keep a closer look at the rest of the top-grade oysters, maybe it will help. ”

Shen Lingyi shook his head, "It's not realistic, although the scale of our farm is not large, but there are not a lot of high-quality products, there is no way to monitor them one by one by relying on those underwater monitors, even if you really let you monitor them all, so many targets, we are not even sure when the pearls were stolen, this kind of monitoring volume is no less than the Skynet system monitoring every license plate number on the peak section of the city." ”

I sighed and said, "Our biggest problem right now is that our goals are too broad. ”

Su Er raised his wrist and looked at his watch, "Aunt Shen, Uncle Xi said that the farm regularly fishes up all the female oysters to be cleaned and observed, so what is the next observation time?"

Shen Lingyi also looked at her watch, "Two days later, and this work will last for several days." ”

Su Er said: "I have an idea, I don't know if it will work. Shen Lingyi motioned for her to take a look.

"During this cleaning, we artificially distorted the original oyster number and transferred the top oyster to a nearby cage, most of which were covered with fine barbed wire. This has two advantages: one is that only a few of us know about the new number, so we can determine if something is wrong with the data analysis room. ”

"Another advantage is that the upper grade oysters are relatively concentrated, and most of them are protected by us, so that we can let the underwater monitor monitor a few cages in a targeted manner, which is equivalent to putting some bait, so it is not necessary to monitor them one by one, as long as the opening and closing of the oysters in these baits can be seen. I just don't know if it's feasible or not. ”

Shen Lingyi pondered for a long time, "Although this will have a little impact on the mother oyster, I think it is feasible, I will discuss it with Bu Fan to see if I want to do this." In fact, when she said this, she had basically approved Su Er's plan, but the implementation still needed to be coordinated and considered.
