Metropolis: Sign in for 30 Days, My Reasoning Is Invincible

Chapter 727 : Doubtful [seeking subscription]

Although you can definitely find it if you look for it, it is obviously not suitable for free activities now, so Qin Feng chose to ask directly.

Xiao Cheng pointed directly to the front right and said.

“Just over there, come with me.”

After talking, Xiao Cheng led the way to the stolen booth.

Qin Feng looked at the booth in front of him and observed it carefully.

What can be confirmed is that the booth is empty and the booth itself is intact.

If there is nothing in it, it won’t make people feel abnormal at first glance.

Seeing this, Qin Feng immediately asked a question.

“The first two times are the same as now?”

Xiao Cheng nodded in response.

“Yes, the first two times were like this on the surface and it seemed nothing unusual.”

After confirming the previous two situations, Qin Feng circled the booth in front of him and said.

“This unfolded state is intact, which means that the thief opened the booth through normal means and took the things away?”

Xiao Cheng nodded in response.

“It should be like this, because it is normally turned on, so there is no triggering of the alarm system.”

Hearing this, Qin Feng glanced at the booth where the password was entered. Obviously, to open the booth normally, you must know the booth password.

“Are these booths using the same password?”

It is also the first time that Qin Feng has seen the situation at the scene, so many questions can only be asked from the beginning.

However, Xiao Cheng did not refuse to answer.

“No, there are hundreds of booths here, and each booth uses a different password, all of which are independent.”

Hearing the different passwords, Qin Feng couldn’t help but look around.

In this exhibition hall, there are hundreds of booths, and a few pieces of jewelry are placed in each booth.

All of them use different passwords, which means that hundreds of passwords have to be recorded to open all these booths.

After looking around, Qin Feng turned around and asked.

“Excuse me, how are these passwords usually recorded? Are they all in my head”,?”

Qin Feng knows that it is very difficult to remember hundreds of passwords at the same time, but it cannot be said that this is absolutely impossible.

Xiao Cheng shook his head in response.

“These passwords are all recorded in a cipher book.”

Hearing this response, Qin Feng didn’t feel surprised.

“Well, can you be sure that this codebook has not been read by a suspicious person?”

Qin Feng knows very well that the password book should have been investigated.

But this matter has nothing to do with me, so I can only ask directly if I want to know the situation.

Xiao Cheng did not answer directly, but took out a boxy thing from his pocket and showed it in front of Qin Feng.

“This is the cipher book. It is not a paper cipher book, but an electronic cipher book. It uses a dynamic password. I can be sure that no one else has touched this thing, only I have touched it.”

Seeing that the password system used here is such a high-tech thing, Qin Feng would like to take it over to see the specific situation.

But I also knew that it was not appropriate to do so, so Qin Feng Jiao just stood there and looked at it, and then asked a question.

“This electronic codebook is only owned by you. There is no backup?”

Xiao Cheng nodded and said.

“Yes, there is only one.”

Qin Feng immediately asked a new question.

“If this electronic codebook is damaged or lost, wouldn’t it be impossible to open these booths in this exhibition hall?”

Qin Feng glanced at the surrounding booths again.

The tops of these booths are covered by glass, but Qin Feng also knows that these glasses are definitely not ordinary glass, and they are not so easy to break.

Xiao Cheng also answered Qin Feng’s hypothetical question.

“I kept this thing very carefully, but even if it is really damaged or accidentally lost, there are alternative means to open these booths.”

Seeing that there is still a backup method, Qin Feng is about to ask what the backup method is.

But before he spoke, Xiao Cheng took the initiative to explain the situation.

“Although there is a backup method, it is impossible for thieves to use this backup method. This system is specially customized by me. The person who made this system is a trustworthy person. He has a backup method that can be opened. Booth. ”

Upon hearing this explanation, Qin Feng said immediately.

“Is it sure that the alternative means will not be used?”

Xiao Cheng nodded affirmatively in response.

“It is certain that it will not be used, and even if it is really used by the thieves, then these thieves must be able to enter this exhibition hall. The security system outside this exhibition hall is separately customized.

“If all the thieves use backup methods, they have to steal the backup methods from different companies first.

After listening to these words, and looking at the firm (Zhao Li Zhao) expression on Xiao Cheng’s face, Qin Feng understood that unless clear evidence was found.

Otherwise, Xiao Cheng would definitely not think that the thief had stolen the backup method first.

Of course, Qin Feng also understands that, according to Xiao Cheng’s explanation, it is indeed quite difficult to get all the spare methods in order.

But just in case, Qin Feng still asked a question.

“Then have you investigated the companies that make security systems?”

No matter how Xiao Cheng believes that those thieves cannot steal alternative means.

If you haven’t investigated the companies that customize security systems, this can be considered an omission.

At this time, Xiao Tianduan spoke.

“This has been investigated, the police have investigated, and we have also investigated and we have not found any signs of theft.”
