Zhang Meiling said: "The police asked the security guard and saw a surveillance security guard, but he did not care about it. He guessed that he used a high-end cutting mask. After all, the pixels of the surveillance are limited, and the police's skull comparison has no results. If it is not a criminal record, it is a filler to add a mask. "It is not that a coin can be used to hide the skull comparison system. People with certain professional knowledge must be able to make the skull recognition system unable to recognize the skull."

Zhang Meiling said: "The legal ID card download cannot be completed by a genius in the design company, and the security guard can do it. However, the security guard cannot enter the design company."

Nie Zuo said: "There is a flaw."

"Please say it."

"These designers must have never done rough work. The secret key is in the hands of the security guard. If the designer's inner fellow wants to unlock the lock, they can only use theft skills to unlock the lock. We can see if there are any bruises on their hands."

"It's hard to say." Zhang Meiling shook her head: "It was the next day that we thought about this possibility, and the bruises disappeared. Besides, it may not be that the thief got the key and handed it to the insider. You also said that these designers have never done such a thing, and the thief was not at ease to let him do it."

"It makes sense." The time was pinched very accurately. If you were not sure about unlocking the lock, the thief would be trapped. The patrol security guard found that the thief entered was opened, and the thief would be unable to fly. Nie Zuo had a headache, and the police were not easy to be aware of. He also had to include the security guard's confession, read the surveillance, and then understand the key storage rules, etc., to rule out one possibility after another. He was not a policeman, so don't do this. Since there were many possibilities, he would choose the least possible entry point. Nie Zuo asked: "This safe is the latest product of a German company. It is difficult for ordinary people to open it in five minutes, right?"

Zhang Meiling and Nie Zuo and Wei Lan were drinking tea. Zhang Meiling tapped on the laptop and said, "It is true. This safe has two locks, one is the key and the other is the password. The old-fashioned password mechanical lock, turn left first and then turn right like this safe."

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

Zhang Meiling was enlightened: "Yes, this old-fashioned mechanical password lock is rarely used now, so it's too inconvenient. Qi Tong ordered it directly from Germany. We can contact German merchants to see who has ordered the same model of products in City A or Dongcheng. I'll call."

Nie Zuo smiled: "Look, we are really much more relaxed when we have a policeman helping us."

Wei Lan looked around and said, "Nie Zuo, I still have a certain view on Liu Jiang."

"No need to keep it, he was sent by the Internal Service Department of Wanlian International to survey the situation." Nie Zuo said: "This man is very slippery, he speaks people's words and talks to ghosts. He can go from a despicable person to a person who abides by his oath and a prodigal son who returns and does not change his gold. There must be a problem."

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

"He and his two foreigners are veterans of the British escort company. This website was built by their veterans." Nie Zuo said: "I can't see any malice. The new company has just been established and many errands need to be done. Don't expose others first."

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

"Ah... is this a small advantage?" Nie Zuo thought for a while: "Okay, I'll turn around and say to him. I'll ask you to replenish the freezer tomorrow and make an account book. After all, we are a company, and it's not OK to have no account book. There are also some common medicines, mainly trauma medicines installed in the company's freezer. You need to buy disposable paper cups, coffee beans, and you have to make an appointment to housekeeping. I'm too lazy to do hygiene anyway. If you are diligent, this one can be saved. Tomorrow afternoon..."

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

"I think so too." Nie Zuo returned to the commission and said, "If there is an insider, it makes sense. Qi Yun took away sixty design drawings half an hour in advance, how could the insider not know? This is not a small company. If you take such an important thing, there must be a set of procedures. I personally prefer that the thief came for these twelve diamond design drawings."

Wei Lan nodded: "If this is the case, I suspect that the focus is the gold and gem group. Otherwise, if you change the time, all of them will be stolen. The gold and gem group do not want to lose their bonuses themselves, and they have to work overtime, so choose the right time."

"There is another problem that makes no sense. This is a team theft case. Even if the insider knows that Qi Yun will take away the design drawings, how do you know that it will be taken today? Not tomorrow? Why is it 8:30, not 7:30? The thief time needs to be calculated accurately to avoid the security guard." Nie Zuo said: "I just learned about the procedure. Qi Yun, accompanied by Qi Tong, opened the safe and handed the design drawings to Qi Yun. Qi Yun brought the secretary. The office was upstairs, and there was a security guard in the corridor. Wei Lan, you..."

Wei Lan smiled: "I have learned that Qi Yun only took 60 design drawings because the master of the processing factory was in the office. The master was very experienced in gem inlay and gold processing, but was not familiar with diamonds, so he only took 60 copies. At the same time, Qi Tong and Qi Yun told Qi Yun that some details of the diamond design drawings still need to be modified and not completely fixed. Qi Tong did not lie, and the diamond group originally planned to make subtle modifications to the three design patterns on the day of theft."

Nie Zuo said: "Since there are conflicts and various possibilities, let's start with the thief. I believe my judgment is that if I want to open a safe in such a short time, it is very likely that I have purchased a safe of the same model to practice."

Strictly speaking, Nie Zuo and Wei Lan cooperated for the first time, but the two cooperated quite well. Wei Lan basically understood Nie Zuo's ideas and chose the simplest and least possible person or thing as the entry point. Simple, concise, and quick entry into the role are Nie Zuo's characteristics. Generally, men with such personality are more powerful.

Zhang Meiling soon received news from German merchants that since people now prefer electronic password locks, only two safes of this model are sold in City A and Dongcheng. The buyer of one is Qitong, and the buyer of the other is Mai Zixuan, the chairman of Oceanwide Group and Mai Yan's biological father.

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

Zhang Meiling said afterwards: "I should have thought that even if we need to practice the safe, we would not be able to find it so easily, and it is a mechanical password lock that few people use. I have asked the Interpol to help to see if we can obtain global sales information, but this may require legal procedures, and we will find it difficult to rule out the suspicion of foreign buyers." The subtext is, Nie Zuo, your method will not work, and you cannot catch the thief from the safe.
