Fujita Yoshimasa's words caused the entire conference room to fall into silence.
However, the silence did not last long. Li Qiang stood up and said: "Reporting to Chief Fujita, I am humble and incompetent. Although I have only scratched the surface of deciphering work, I can see some clues from your description just now. I wonder if it is possible."
Allow me to help you analyze it?"
Someone took the initiative to speak, and Fujita Yoshimasa naturally wanted it, so he quickly made a "please" gesture and said to Li Qiang: "In that case, please ask Captain Ming to help analyze it!"
So Li Qiang simply left his seat, walked to the blackboard, and used colored chalk to circle the areas where there were differences in the deciphering results of the three groups.
"Please see, the three places I have circled are the key to the different deciphering results of our three teams, and they are also what troubles Chief Fujita the most. In that case, why don't we put aside those overly professional deciphering methods for the time being.
Program and focus on a simple logic problem?"
With that said, Li Qiang continued to use chalk to write the three numbers "three, four, five" on the blackboard.
Then he continued: "Please see, these three numbers represent our three groups. If the deciphering result of the third group is correct, it means that the deciphering result of the fourth group I am in has three errors, and
The fifth group has two errors; conversely, if the fourth group's deciphering result is correct, then the third group has three errors, and the fifth group has one error; finally, if the fifth group's deciphering result is correct
, then the third group has two errors, and the fourth group has only one error. I believe that everyone here is an excellent deciphering expert, so from a probability perspective, it should be the third situation
The highest credibility!”
As soon as these words came out, Hu Xianzhou, the leader of the third team, nodded proudly and immediately responded: "Captain Ming is right, I have deciphered so many sealed messages and I have never made any mistakes.
How could it be wrongly translated?”
However, before he finished speaking, Li Ningyu stood up and said: "I admit that although our team leader only talked about probability issues, it is still of reference value to a certain extent. But if you want to get the final conclusion, then the previous three
This hypothesis must be established. But just now, when Chief Fujita sent people in to collect the deciphering results of the third team, Professor Hu not only took a look intentionally or unintentionally, I think he was just looking at it.
What’s the last date for action?”
"You...are talking nonsense! How could I, a senior confidential information consultant of the Secretariat, do such a despicable thing?"
"Really? Then I would like to ask Professor Hu, what method did the other party use to encrypt the last date of the encrypted message?"
As soon as these words came out, Professor Hu was obviously a little panicked, "I...why should I tell you this?"
Before he finished speaking, Fujita Yoshimasa said with a calm face, "Professor Hu, please answer Captain Li's question head-on!"
"I……"
Seeing that Professor Hu was hesitant and speechless for a long time, Li Ningyu chuckled and continued: "What, can't you tell me? Tell you the truth, this last date, the other party chose the one you despise the most.
It is encrypted using a mathematical method, that is, the Möbius function formula. If you want to crack it, you only need to substitute the last piece of code into the formula and reverse it."
After saying that, he turned to look at Cheng Hesheng, a member of the third team, "Am I right? Mr. Cheng?"
"Yes, it is the Möbius function." Cheng Hesheng nodded simply and said, "But according to my calculations, the inference result is clearly fourteen, which is Hanri, but why did you decipher the result to represent this
What about New Year’s Day on the 13th?”
Before he finished speaking, before Li Ningyu could speak, Li Qiang took the initiative to take over the conversation, "It's very simple, because the sending and receiving organization of this sealed message is the military commander, and it is very likely that Dai Li personally issued the order. According to my experience in the Northeast Manchurian Railway,
Based on my experience, for secret messages like this, they often postpone the critical time by one day to prevent the secret message from being deciphered. Therefore, I concluded that the final deadline is not Hanri, but Yuanri!"
"That's it!" Hearing this, Fujita Yoshimasa suddenly nodded, and then immediately turned his head and asked Professor Hu sternly, "Professor Hu, can you please explain why you peeked at the third
The team’s deciphering results?”
"I...I didn't..."
"Baga!" Seeing that Professor Hu not only refused to plead guilty, but was still making excuses, Fujita Yoshimasa slammed the table and cursed, "In front of so much evidence, you still want to make excuses?"
"Sir Fujita, I..." Professor Hu was still desperately trying to explain.
The team member on the side stood up and took the initiative to confess: "Mr. Fujita Mingjian, the professor did not lie. We really did not peek at the deciphering results of the third team. The reason why the professor could not tell the other party's encryption method was because in the end
I deciphered that coded message. Because the Möbius function formula was used, the teacher was reluctant to accept my deciphering results until he saw Captain Li and his team submitted the deciphering results, and then he had to be very reluctant.
I added my deciphering results."
"If things are really as you said, it's understandable." Fujita Yoshimasa said thoughtfully, and then glanced at Yunzi Minami who was standing aside. Seeing the latter nodding slightly, he suddenly changed the subject, "It's just that
But Captain Ming saw with his own eyes that Professor Hu peeked at the deciphering results of the third team, could it be that he was lying?"
Not wanting these words to come out, before anyone else could speak, Li Qiang took the initiative and said, "Sir Fujita, to be honest, I did lie just now."
Now not only Fujita Yoshimasa, but everyone present was confused.
Li Qiang explained unhurriedly: "Sir Fujita Mingjian, if I don't tell this lie, how can I get Professor Hu's team members to tell the truth?"
"So, you've been going around for a long time just to embarrass Professor Hu in public?" Fujita Yoshimasa said very unhappily.
Li Qiang shook his head without thinking, "No, no, no, of course not. I just want Professor Hu to admit in person that he deliberately reported the wrong date to Mr. Fujita even though he knew the exact date."
"You're talking nonsense! How...how could I do such a thing?"
"Professor Hu, please don't be so excited. Although I'm not particularly good at deciphering, I have a good memory. If I remember correctly, you should be a convert, right?"
