Zhang Meiling said: "The police asked the security guard, and the security guard did see a man, but he thought he was a member of the design company, so he didn't care." The guess is that a high-end cutting mask is used, and the pixels monitored are limited after all, and the police skull comparison has no results. If not without a criminal record, it is the addition of padding to the mask. "It's not a coin that can be used to get past the skull comparison system, you have to have someone with some professional knowledge to make the skull recognition system unable to recognize the skull through the guò filler."

Zhang Meiling said: "The download of legal ID cards is not only done by ghosts in the design company, but also by security guards. However, security guards are not allowed to enter the design company. ”

Nie Zuo said: "There is a flaw. ”

"Please."

"These designers must not have done rough work, this secret key is in the hands of the security guard, and the designer has to open the lock, so he can only use theft skills to open the lock. We can see if there are any bruises on their hands. ”

"It's hard to say." Zhang Meiling shook her head: "We only thought of this possibility the next day, and the bruises also retreated." Besides, it may not be that the thief got the key and handed it to the inner ghost. As you said, none of these designers have done anything like this, and thieves don't feel comfortable letting him do it. ”

"Makes sense." This time is very accurate, and if you are not sure to open the lock, the thief will be trapped. When the patrolling security guard discovers that the secret lock that the thief has entered has been opened, the thief has no wings. Nie has a headache on the left, the police are not good, and he has to record the confessions of the security guards, watch the surveillance, and then understand the rules of key storage, etc., to eliminate one possibility after another. I'm not a policeman, don't come like this, since there are many possibilities, then choose the entry point with the least possibility. Nie Zuo asked: "This safe is the latest product of a German company, and it is difficult for ordinary people to open it in five minutes, right?" ”

Zhang Meiling, Nie Zuo, and Wei Lan were drinking tea, Zhang Meiling tapped on the laptop and said, "That's true, this safe has two locks, one is the key, and the other is the password." Old-fashioned password mechanical locks, first turn left, then turn right such a safe. ”

"Qi Tong is a bit old-fashioned, he doesn't trust computers, not even electronic passwords." Nie Zuo said: "This kind of mechanical lock safe is not something that ordinary veterans can open. Given that it is the latest model this year, if you want to unlock it in five minutes, you must order one to practice at home. ”

Zhang Meiling was like an empowerment: "Yes, this old-fashioned mechanical combination lock is rarely used now, and it is too inconvenient." Qitong is ordered directly from Germany. We can contact the merchant in Germany to see who has also ordered the same model of product in City A or Dongcheng. I'm going to call. ”

Nie Zuo smiled: "Look, there is a policeman to help, we are really much easier." ”

Wei Lan looked left and right: "Nie Zuo, I still have a certain opinion on Liu Jiang." ”

"There is no need to keep it, he was sent by the Internal Affairs Department of Wanlian International to find out." Nie Zuo said: "This person is very slippery, he talks about people when he sees people, and he talks nonsense when he sees ghosts." He can change from an obscene person to a person who keeps his oath and does not change the money of the prodigal son. There must be a problem. ”

"But you gave him a pass to escort the page."

"His eldest and two foreigners are veterans of the British escort company, and this website was built by their group of veterans." Nie Zuo said: "I don't see any malice, the new company has just been established, and there are a lot of errands to do, so don't expose others first." ”

Wei Lan looked at Nie Zuo in disbelief: "I really can't see it, you take advantage of this little advantage." ”

"Ah...... Is this a small bargain? Nie Zuo thought for a while: "Okay, I'll go back and talk to him, tomorrow please supplement the things in the freezer, and make another account book, after all, we are a company, no account book." There are also some commonly used medicines, mainly trauma medicines, which are equipped in the company's freezer. Disposable paper cups to buy, coffee beans to buy, and to make an appointment for housekeeping, I'm too lazy to do hygiene anyway, if you are diligent, this can be saved. ...... tomorrow afternoon"

Wei Lan immediately said: "I think Liu Jiang is very diligent, it's good to keep it." ”

"I think so too." Nie Zuo returned to the commission and said: "If there is an inner ghost, it doesn't make sense. Qi Yun took sixty copies of the design drawings half an hour in advance, how could the inner ghost not know? This is not a small company, and there must be a set of procedures for taking such an important thing. Personally, I'm still biased towards thieves, and that's for these twelve diamond blueprints. ”

Wei Lan nodded: "If that's the case, the focus of suspicion is the gold and gem group, otherwise it's good to change the time and steal them all." The Gold & Gem team doesn't want to lose their prize money and work overtime, so pick the right time. ”

"This doesn't make sense again, this is a teamwork theft, even if the inner ghost knows that Qi Yun will take the blueprint, how do you know that it will be taken today? Not tomorrow? Why is it half past eight, not half past seven? Burglars need to be accurate in their time to avoid security. Nie Zuo said: "I just understood the procedure, Qi Yun was accompanied by Qi Tong, Qi Tong opened the safe, handed over the design to Qi Yun, Qi Yun brought the secretary, the office is upstairs, and there are security guards and monitoring in the corridor. Wei Lan, you ......"

Wei Lan smiled: "I have already understood, Qi Yun only took sixty copies of the design drawings, because the master of the processing factory was in the office, and the master was very experienced in gem setting and gold processing, but he was not familiar with diamonds, so he only took sixty copies." At the same time, Qi Tong and Qi Yun said that some details of the diamond design plan still need to be modified, and they are not completely finalized. Qi Tong didn't lie, the Diamond team had planned to make minor changes to the three designs on the day of the theft. ”

Nie Zuo said: "Since there are contradictions and various possibilities, let's start with thieves first." I believe my judgment, to open a safe in such a short period of time, it is very likely to buy the same model of safe to practice. ”

Strictly speaking, Nie Zuo and Wei Lan cooperated for the first time, but the two cooperated quite tacitly, and Wei Lan basically understood Nie Zuo's thinking, and chose the simplest and least possible person or thing as the entry point. Simple, concise, and quick to enter the role are Nie Zuo's characteristics, and generally men with such a personality are relatively strong.

Zhang Meiling soon received feedback from German merchants, because people now prefer electronic password locks, so this model of safe is only sold to City A and Dongcheng only. The buyer of one is Qi Tong, and the buyer of the other is Mai Zixuan, the chairman of Sino-Ocean Group and Mai Yan's biological father.

"Only these two?" Nie Zuo asked in surprise, thinking that he was a detective, but he didn't expect it to be.

Zhang Meiling said with hindsight: "I should have thought that even if we needed to practice in the safe, we would not be able to find it so lightly, and it was a mechanical combination lock that few people use." I've asked Interpol to help me get global sales information, but this may require legal proceedings and we can't rule out foreign buyers. "The subtext is, Nie Zuo, your method won't work, you can't track down the thief from the safe.
