Mu Yuan put his head over and took a look with a calm expression.

The safe is not particularly big, only half a person tall, but it is definitely one that cannot be moved by one person.

At this moment, on the back of the safe, there was a hole with neat seams and traces of high-temperature burns.

"This should have been opened by some kind of flame cutting machine." Mu Yuan said, "Where is the cut piece? Was it taken away by the suspect?"

Manager Lu quickly said: "No! I put it over here."

After speaking, Manager Lu opened a nearby filing cabinet and took out a heavy piece of iron.

The material is the same as the safe.

Manager Lu said angrily: "This piece was installed behind the safe before. If I hadn't discovered that the money inside had been stolen and carefully checked the safe, I wouldn't have known that the safe had been damaged."

"This thief is so arrogant! How dare he destroy the safe so blatantly..."

"It's not blatant, it must have been done secretly." Mu Yuan responded seriously.

Manager Lu glanced at Mu Yuan with a strange expression, "Why is this young man talking so strangely?"

"I know it was cut secretly!" Manager Lu said, "But... isn't it arrogant to dare to take a cutting machine to a public place like an office to cut the safe?"

"It's really arrogant!" Mu Yuan stopped paying attention to the safe because there was no need to look at it.

"When did you put the money in the safe?" Mu Yuan asked casually.

"Five days ago, that is, this Monday morning." Manager Lu said.

Mu Yuan frowned slightly and asked again: "When did you find out that the money was stolen?"

"Yesterday afternoon! I called the police after I found out."

Mu Yuan looked around, pointed to a camera in the corner, and asked, "I heard that the surveillance system was out of order for a while? When was it?"

Manager Lu said: "It's not a fault with the camera, but a fault with the circuit from the night before yesterday to last morning. It is said that the circuit breaker tripped."

Mu Yuan was full of frustrations. Security facilities such as cameras did not accept UPS?

But for financial managers like Manager Lu, they may not even know what ups is.

He didn't bother to ask more questions on this issue, and said directly: "Can you please invite your person responsible for electrical maintenance? There are some things I want to ask him."

"Didn't you ask me yesterday afternoon?" Manager Lu didn't understand.

Mu Yuan asked seriously: "I want to know more details."

Manager Lu just said this casually, so she agreed with Mu Yuan's reason, which was not a reason.

Then Manager Lu made a phone call, and then waited for the electrician to come over.

Mu Yuan was not idle while waiting. He looked at the safe in a daze.

Really dazed.

This case occurred within ten days, so it stands to reason that his time-traveling talisman can easily solve it.

But this case is very troublesome.

The stolen items were placed in the safe, and if I stood outside and used the time-traveling charm, even if my eyes were bloodshot, all I would see was the safe sitting there quietly.

As for when the money in the safe disappeared, he couldn't see it at all.

In addition, there is a damaged surface behind the safe, which is also blocked by the wall. Unless you can move the safe, you can't see when it was damaged.

Unable to determine a reference object for him to use the dichotomy method, if Mu Yuan uses the time-traveling talisman to determine when the money inside was stolen, the price would be too high.

Unless Mu Yuan can let Xiaomao get into the safe in mouse form.

But obviously, this is not a suitable place to close the door... let Xiao Mao go.

If Xiaomao could be made the size of a fly, or even smaller than a fly, this problem would be solved.

But there are only a few cases like this. It is really not cost-effective to use Xiaomao's third form just for this case.

He was thinking about this case...how to solve it without using the time-traveling talisman?

In the process of questioning Manager Lu just now, he had already observed him through his expert psychological lie detection technology, and the results showed that there was a high probability that the other party was not lying.

This basically eliminates the possibility of Manager Lu committing theft.

"How many people know that you have money in this safe?" Mu Yuan asked.

"Our finance department basically knows it," Manager Lu said. "Next Monday is the tenth anniversary of the founding of our company. According to tradition, the company will send a red envelope to each employee, and this money is used to seal the red envelope."

Mu Yuan felt a little envious. This was someone else's company! It was inhumane to receive a million red envelopes!

But then I thought about it, this company is so big, it seems...a million red envelopes, distributed to everyone, is not too much.

At least it’s much less than a second-class meritorious service!

Putting aside these strange thoughts, the other party's explanation at least explains why he suddenly needs to put cash in the safe.

"What do you usually keep in this safe?"

"This safe is empty most of the time, mainly used to store cash," Manager Lu said.

"What about this safe?" Mu Yuan asked, pointing to another intact safe.

"This is used to store documents, and there are also some important procurement contracts."

Mu Yuan murmured: "It seems that the person who stole the thing knows the difference between the two safes."

Manager Lu said helplessly: "There are nearly 20 people in our finance department who basically know what these two safes are for."

Mu Yuan looked at Manager Lu, feeling helpless.

As a leader, do you need to trust your subordinates so much? You want to let others know everything, so you can't keep a little privacy?

"Who still has the key to your office?"

Manager Lu gave a bitter smile and said: "I am the only one who has it! This is also my biggest headache. There is no sign that the door has been pried. I am indeed suspected of being a thief. If it weren't for the trust of the board of directors in me, I guess I..."

Manager Lu didn't say anything else, but others could guess it.

One million is not a lot for such a group company, but if it is stolen, it is stolen. At least, the board of directors will not let a person who is suspected of committing theft continue to serve as the financial department manager.

It can also be seen from this that Manager Lu’s character is quite good.

Just then, a man knocked on the door and walked in.

The person who came was a man in his thirties, wearing work clothes.

"Hello, Manager Lu!" The man greeted somewhat cautiously.

"Gong Li, these guys are from the Public Security Bureau. They want to ask you something. If you know anything, just say it boldly." Manager Lu said.

The man immediately nodded in agreement.

Mu Yuan's eyes fell on his face and asked: "Gong Li, I have a question. Don't the cameras here have separate ups?"

Li Gong's expression was still a little nervous and said: "Yes, the other surveillance cameras were all connected. However, the camera in Manager Lu's room was installed later, and at that time the Finance Department required that this camera not be connected to the monitoring center, so there was no

It uses centralized UPS power supply, but shares a set of lines with the lighting lines here."

"Who in the company knows about these situations?"

"Well... I'm not sure. This camera has been installed for two or three years."

Mu Yuan hesitated for a moment, then turned to look at Lai Yang and asked, "Lai Yang, have you checked the surveillance cameras entering and exiting the building? Have you found anything suspicious?"

Lai Yang said: "We have copied all the surveillance for the past five days and conducted a series of analyses. For the time being... we haven't found anything yet."

Mu Yuan has a headache...
