Chapter 178 Purple Secret Change

"Lao Qi."

Qin Chuan's voice made Qi Lanfeng involuntarily retract his gaze and look at the map.

Qin Chuan thought about it and said, "We should hurry up and prepare here."

Qin Chuan's words surprised Qi Lanfeng at first, and then he understood what Qin Chuan meant.

"Are you saying that our place will soon become a battlefield?"

"Yes." Qin Chuan nodded affirmatively.

"Lao Qi, think about it, Shanghai is only more than 300 kilometers away from Jinling. It is more convenient to take the waterway. It can be said to be very close! And don't forget, there are thousands of fully armed Japanese marines stationed here.

If they mobilize, it will not be a problem for the Japanese expatriates in the concession to arm thousands more."

"Also, since the 128th Anti-Japanese War in Shanghai, according to the agreement, our troops are not allowed to be stationed in Shanghai, so do you think that if there is a war in the north, our place will be peaceful?"

Qi Lanfeng nodded and said, "You are right, we should make preparations immediately."

After thinking for a while, Qi Lanfeng said again, "Chengji, what preparations do you think we should make now?"

Qin Chuan nodded and said, "If we want to make preparations, we must first keep an eye on the Japanese in the public concession, not just the Japanese Marines, but also the Japanese expatriates in the concession, and closely monitor their movements; secondly, for us

We must keep an eye on the Japanese spies hidden among the people. Once the war breaks out in Shanghai, we can even eliminate these people in advance before the war starts, so as to avoid further assassination during the war.

Exploring our military intelligence; we must also pay attention to our actions to be more cautious and not to expose the identities of potential personnel in advance. Anyone whose identity is leaked must evacuate Shanghai; also, it is our company's business, and we must arrange for us to stay in the United States

The personnel are trying their best to bring back more sulfonamides from the United States as soon as possible in a short period of time, so that if war breaks out, it will be difficult to obtain these life-saving drugs."

"Ring, ring!" The phone on Qi Lanfeng's desk rang again. Qi Lanfeng picked up the phone, listened for a while, looked a little nervous, put down the phone and said to Qin Chuan.

"Chengji, follow me to the deciphering team. Something happened there."

After saying that, Qi Lanfeng strode out.

"Something happened to the deciphering team!"

Qin Chuan couldn't help but be shocked by Qi Lanfeng's words. Although these people were much worse at deciphering secret messages than him, they were much better than most telecommunications personnel in the country at this time. If anything happened to them, they would definitely be killed.

It's a special station, no, at least it's a big loss for their department in deciphering secret messages.

It's just that Qin Chuan can't understand. Apart from going home from get off work at night, these people stay in the dark room of the deciphering team almost every day during the day. What will happen to them?

Could it be that Zheng Yusen was exposed? When he thought of this, Qin Chuan couldn't help but feel nervous, thinking to himself, at this time, such a thing must not happen.

Fortunately, the mystery was revealed in less than a minute.

In the deciphering room, Wang Jiali looked annoyed and kept walking back and forth in the small corridor in the room. More than ten people in the deciphering team sat dejectedly in their respective seats, staring blankly at the coded manuscript in front of them.

, only Li Mo, the team leader of the deciphering team, stood on the other side of the aisle, showing a helpless wry smile.

In view of the great achievements of the special station in deciphering, the director has enjoyed the benefits. At the end of last year, you added ten more members to the special station, and now the number of members in the deciphering team has reached sixteen.

These people receive Qin Chuan's personal answers to questions once a week. The rest of the time, Liu Jie and Zheng Yusen teach them in rotation, and the main lectures are the courses Qin Chuan taught Liu Jie and Zheng Yusen at St. John's University.

Due to basic reasons, although these people are still not as good as Qinchuan's two students, they have now basically reached the level of using mathematical tools to help decipher the secret messages. This has also greatly improved the decryption efficiency of the special station. Now

Since we have mastered the frequencies and codes used by several Japanese institutions and more than a dozen overt or covert radio stations, most of the encrypted messages sent by radio stations including the Japanese embassy and consulates and the naval attaché office can be deciphered, with the lowest level of decipherment.

can also reach 60%.

This situation of being unable to do anything like today has not happened for a long time. Seeing the expressions of Wang Jiali and others in the room, Qin Chuan already understood that this must be a new problem in deciphering.

Sure enough, when he saw Qin Chuan and Qi Lanfeng coming in, Wang Jiali immediately walked a few steps to Qin Chuan and said, "Chengji, the Japanese embassy and consulate must have changed the password. We can't decipher it. What do you think we should do?"

After asking carefully, they found out that the secret message in front of them was the secret message of the Japanese Consulate in Peiping intercepted this morning. However, when they were deciphering it, they suddenly discovered that the Japanese had changed the new password.

After learning about the situation, the team leader Li Mo immediately notified the people on the shift, including Liu Jie, Zheng Yusen and other people with better deciphering skills, and immediately started organizing the deciphering. However, they have been busy for more than two hours and still have no clue.

No, they also knew very well that the secret messages sent by the Japanese were very important information for the Kuomintang, and they did not dare to delay. In desperation, they had to report the situation to Wang Jiali.

However, Qinchuan knew that the Japanese diplomatic code was called "Purple Secret" for short. It was the most advanced, largest and most complex code of the Japanese. After three or seven years, the Japanese began to continuously change and upgrade the "Purple Secret".

During the period after World War II, the Japanese replaced and upgraded the "Purple Secret" five times, so you can imagine the difficulty of deciphering it.

The last time they deciphered this code, it took several months. This was thanks to the systematic help of Qin Chuan. He had mastered mathematical deciphering methods that were about ten years advanced. If they wanted to successfully decipher the Japanese code after they changed it in a short time,

It will definitely not be completed in a short time.

Qin Chuan patted Wang Jiali's arm and said softly, "Old Wang, the situation is urgent now. It is normal for the Japanese to change their passwords. This matter cannot be rushed."

Then Qin Chuan turned to everyone in the deciphering team and said, "Thank you for your hard work. You have done a good job recently. Through your unremitting hard work, our deciphering team has achieved remarkable results, and the department has awarded us many awards."

After listening to Qin Chuan's words, the expressions of everyone in the deciphering team softened a lot.

Qin Chuan continued, "This time, the Japanese suddenly changed their code. You couldn't decipher it in a short time. This is not because you are incompetent. You should know that the Japanese diplomatic code is their most complex large code."

"However, no matter how difficult the task is, we cannot give up easily. If we can decipher this code, it will be of great help to the Kuomintang Party's decision-making, so we have to work hard. In this way, you will assign a group of people to be responsible for deciphering the Japanese code.
