I was framed for taking the civil service exam, so I joined the National Security Bureau

Chapter 230

Zhang Xing's face was still solemn. He carefully took out the paper with the number problem from his pocket and handed it to Lao Banjiu steadily.

"Captain Lao Banjiu, I think you should be familiar with this number problem on the paper, right?"

Zhang Xing's eyes were like two sharp arrows, shooting straight at Lao Banjiu, as if trying to capture a slight change in his expression.

Lao Banjiu glanced at the number problem on the paper, and a little surprise appeared on his face, as if he had seen something unexpected.

"Isn't this the number problem I asked Shanqi to solve? Why did this kid come to you for help? By the way, have you solved it?"

Lao Banjiu's eyes were full of curiosity and expectation, and his voice was also a little anxious.

Lao Banjiu's reaction made Zhang Xing a little confused. Although Lao Banjiu has been playing Sudoku for many years, it is obvious that the number problem in front of him is very different from the general Sudoku problem.

Furthermore, since the team leader Geng Jianhui had informed Lao Banjiu of all the investigations of the three groups, it was impossible for Lao Banjiu not to know the digital codes mentioned by Director Xu.

The digital problem in front of him had obvious similarities with the digital codes mentioned by Director Xu. Zhang Xing judged that the reason why Lao Banjiu studied such a large number of digital problems was because Geng Jianhui told him about the digital codes.

However, Lao Banjiu did not take the initiative to indicate the relevant connection, and his attitude seemed particularly casual, which made Zhang Xing even more confused.

Zhang Xing looked deep in his eyes and shook his head slowly, indicating that he could not solve the problem. Then he said:

"I heard from Shanqi that Captain Lao Banjiu has been fond of Sudoku puzzles for many years. Whenever he has free time, he will solve Sudoku puzzles for fun. But don't you think that this number puzzle in front of you is very different from the common Sudoku puzzles?"

Lao Banjiu smiled slightly, and that smile seemed to be a bit intoxicated and confident. He nodded gently and said:

"You are right. This kind of similar number puzzle has indeed far exceeded the scope of ordinary Sudoku puzzles. Not only is the number involved extremely huge, but also the number of numbers involved is very large. It is so difficult to find the relevant rules in the numbers. It is no exaggeration to say that there is no rule at all. But I am obsessed with challenging difficult things. The more difficult the number problem is, the more interested I am, and the more I want to solve it and solve the mystery. "

Zhang Xing's eyes were sharp, like two cold lights, and he asked eagerly with a tentative tone:

"Captain Lao Banjiu, where did you get this mysterious number problem from? I am really curious. "

Lao Banjiu did not hesitate at all, his expression seemed very casual, and he said in a relaxed tone: "I found this question by chance from a digital puzzle newspaper, and it was an old newspaper. There is a lounge in the bureau, you should know it? Although the times are developing rapidly and technology is constantly improving, there are modern leisure activities such as electronic toys and computer games, but if we go back five or six years, the biggest leisure and entertainment activities in the lounge were playing table tennis, reading newspapers, and drinking tea leisurely."

"As for me, every time I went to the lounge, the thing I was most keen to do was to read newspapers quietly. The lounge subscribes to a large number of various journals and newspapers every week, and my favorite is this kind of mysterious digital puzzle newspaper. However, with the rapid passage of time in the past few years and the rapid development of the times, everyone has a variety of electronic equipment for leisure and entertainment, and in the lounge There were fewer and fewer people who calmed down to read newspapers and periodicals. Later, the lounge simply cancelled the newspaper subscription service. "

"When I went to the lounge a few days ago, I unexpectedly found that Lao Wang in the lounge was working hard to sort out the old newspapers that had been accumulated in the past. He was preparing to clean up the old newspapers that had been piled up in the small warehouse of the lounge for a long time. The situation at that time was extremely coincidental. Just when he was concentrating on packing, I happened to pass by and accidentally found a few digital puzzle newspapers and periodicals that I loved in the past. The question in front of me was carefully copied from one of those newspapers at that time. "

Although the tone of the old dove seemed extremely sincere, and the sincere feeling seemed to make people completely unable to see even a trace of disguise, Zhang Xing at this moment could hardly believe his current words anyway.

First of all, the old dove's ability to disguise has always been excellent. The more he tries his best to cover up some crucial things, the more he will act very real and natural, making it difficult for people to detect the slightest flaw. Secondly, Zhang Xing is sure that he absolutely cannot be unaware of the connection between this number problem and the number codes that Director Hou solemnly explained.

Zhang Xing was silent for a while, and then he stopped hesitating and asked directly:

"Captain Lao Banjiu, since our team leader Geng Jianhui has told you all the clues of our three groups' secret investigation, do you still remember the number codes that Director Hou explained when we interrogated him? Didn't you find that the number codes he mentioned at that time were very similar to the number problem in front of you?"

Zhang Xing felt that Lao Banjiu was deliberately concealing something. Now he was anxious to find Geng Jianhui, so Zhang Xing couldn't care so much, and simply asked all the questions in his mind.

After hearing this, the old dove was stunned, blinked his eyes quickly and said:

"Let me think about it. Lao Geng did tell me today on the rooftop that you got several sets of digital codes when you interrogated the director surnamed Hou. The numbers of those digital codes seemed to be very large, and there was no pattern to follow. I just heard Lao Geng briefly mention it at the time, and didn't pay too much attention to it. After all, there are many clues in the case, and I can't remember every detail clearly. But after you said that, now that I think about it, it seems that it does have some similarities with the digital problem in front of me..."

Speaking of this, the old dove showed an expression of amazement again, and suddenly slapped his thigh and said:

"Damn, don't say it, I thought of it, the digital problem I copied from the old newspaper is really similar to the digital codes explained by the surname Hou, they are all numbers above five digits, and there is no pattern between them."

"Alas, I'm old, and sometimes my brain works too slowly."
