"Team leader, this is the message they just sent."

"Have you left it to Lao Yang and the others to decipher?" Luo Yao asked with his head raised. The message was a string of numbers. What exactly it said needs to be cracked and translated before he knew.

"Well, I handed it in the first place, but I didn't tell them that this was a new signal we just discovered." Wen Xueren said.

...

Although it is late at night in the office of the Research and Interpretation Team, the task of deciphering is heavy, and basically it is brightly lit.

Most people are working.

"This is an analysis as soon as possible. The Japanese army may have activated a new codeword, or have any special meaning..."

"Team Yang."

"What's wrong?" Suddenly someone called him. Jia Bingwen immediately turned around and looked at him. Zhu Shaoxian, who entered the secret interpretation room with him, entered the military technical room with him. This person is not bad at ease, but he is not good at socializing and taciturn, but he still has the ability.

"Captain Yang, look, this is the intercepted Japanese army message just sent by the listening team. I will study, analyze and decipher according to the secret code we have, and the result is this." Zhu Shaoxian handed Jia Bingwen a piece of paper.

Jia Bingwen took a look at the contents of the two pieces of paper. They both studied Japanese. The translated telegram clearly shows that it is a bad word and cannot understand it at all.

"Has the code word been replaced?"

"I used it, but I still couldn't read it. This is completely a garbled piece of code." Zhu Shaoxian said.

"When the listening team sent it here, did you not say where the telegram was sent?" Jia Bingwen asked suspiciously.

"I've said that it was a telegram sent by the General Staff of the 11th Army of the Central Japanese Army to the Third Division." Zhu Shaoxian said.

"Didn't we have mastered their communication code?" Jia Bingwen said in surprise.

"We have indeed mastered the ordinary communication password, but if they use other encryption methods, it will not work." Zhu Shaoxian.

"Since that's the case, then leave the example and save it." Jia Bingwen breathed a sigh of relief when he heard this. It was nothing. The Japanese army had several levels of communication and telegrams, and what they could currently control was only 60 or 70% of the communications.

It is impossible to fully master it. After all, the Japanese secret communication technology is one level higher than the current national army.

"It's not that the lonely electricity, but that three such telegrams were sent in a row, and the time interval was not long..."

Jia Bingwen frowned slightly, it was not lonely lightning, which meant that it was unusual, and at this time, it must be a very important situation.

“What about the research and translation situation?”

"It's almost the same, it's all garbled, I can't understand it at all." Zhu Shaoxian shook his head.

"In this way, let's go to see the team leader together. This situation is very serious and cannot be delayed." Jia Bingwen said immediately.

"Now, the team leader is already asleep, right?"

"The team leader didn't sleep. When I went out just now, I saw that the lights in his room were still on." Jia Bingwen said.

"good."

...

Jia Bingwen and Zhu Shaoxian came over together and saw Wen Xueren also in Luo Yao's office. They were a little surprised, but after explaining the situation.

I quickly understood what was going on.

All of them came for these three seals of electricity.

Testing, the new communication frequency, three sealed seals were then issued, which obviously changed the seal code. The seal code could be changed, but the operator may not be able to do so.

This is to determine who sent who sent whom the telegram based on the method of sending the news. Otherwise, this can only be regarded as a newly discovered radio wave signal, and it is impossible to determine which party is communicating with which party.

The deciphered telegrams sent by Jia Bingwen and Zhu Shaoxian were all garbled codes that they couldn't understand, which proves that the Japanese army was replacing and enabling new secret codes.

It is already obvious to contact the surveillance of the Japanese army's conventional communications.

The Japanese army wanted to replace and enable new secret codes before the war. Once this action was completed, it was the time for the Japanese army to launch a large-scale attack.

"Tiger, invite Xiaolin over." Luo Yao ordered Yang Fan, Xiaolin was Kishiyao Zhishui, with the pseudonym Li Yuchun.

After a moment.

Kinoshita Chishui followed Yang Fan into Luo Yao's office.

Luo Yao directly handed the original text of the three secret message to Kinoshita Shumi. Speaking of which, the current Japanese communication code can be mastered, so Kinoshita Shumi's contribution can definitely be ranked first.

Because he was too familiar with the secret codes used by the Japanese army, it would be much easier to break from the inside of the fortress.

And it is faster and more efficient.

"This is the work of my senior brother Miura. His favorite is the method of replacing encryption with the last position." Kinishi Kinishi carefully read the three telegrams and said seriously.

Everyone was happy to hear that. It was enough to know who the opponent was, but it was the most difficult to deal with if they didn't know.

"Can you decipher it?"

"Yes, but I haven't seen you for several years. His talent for secret codes is far above me, and he is very good at writing secret codes. He is a recognized genius in secret code communication." What about Kinishi?

“How to say it?”

"There are many types of last-place replacement encryption methods. I can't say which one he will use. I have to try one of them." Kinoshita Kinami said honestly.

"Then try it. How do you say you want to try it? How many people will you help you?" Luo Yao immediately decided that it is the most taboo to decipher the secret code, and also have the courage to take the trial and error.

"It's enough for two people, but it's going to be messed up when there are too many, but you must be someone who knows Japanese. It's best to be familiar with folk songs and verbals in Kyushu Nagatoka area." Kinoshita Kinoshima.

"Miura is from Kyushu Yanoka Prefecture?"

"Yes."

"Okay, Lao Yang, you choose two people to assist Xiaolin's work." Luo Yao ordered Jia Bingwen.

"Okay, I'll arrange it right away."

"Yiming, if there is another telegram, it will be copied directly to Xiaolin." Luo Yao said to Wen Xueren again, "If there is a new similar telegram, please do as per this."

Wen Xueren nodded and agreed.

Luo Yao did not want to maintain a too close relationship with Li Delin, but since he has given a plan, he cannot stay out of the matter.

What's more, I am also in the center of this life-and-death battle, and I can't hide.

It was only two or three hours before dawn, and he had to sleep for a while. He just came and worked all night long. If he really started fighting, wouldn’t he not sleep for several days or nights? After a long time, even the iron man couldn’t bear it.

"Staff General Wei, please help me ask for instructions from De Gong. I want to ask for a meeting this morning." When Luo Yao woke up early in the morning, he found Wei Zhiming.

"Now?"

"Yes, now, I know that Degong is busy with military affairs, but I must see him this morning. This is a major military event, so please make sure you make it clear." Luo Yao said solemnly.

"Okay, I understand." Wei Zhiming nodded. He was appointed as a liaison officer and naturally had to perform his duties.

As for the decision above, this is not something he can control.

...

"Dong De was going to Yicheng for inspection today, and the departure time was postponed. Team Leader Fang, please go there quickly." After a while, Wei Zhiming ran over.

"Okay, I'll come now." Luo Yao agreed, quickly changed into clothes, went downstairs, and got on a car that had already started.

This was the first time Luo Yao came to the commander-in-chief of the Fifth War Zone. This was originally a house for a large merchant. When the commander-in-chief of the Fifth War Zone moved here, the big merchant surnamed Du took the initiative to give up the house and use it for Li Delin.

Three in and three out, dozens of rooms are enough for the office of the commander-in-chief of the Fifth War Zone.

"Report, Team Leader Fang brought it!"

"Please come in."

"yes."

Luo Yao was invited into Li Delin's office in the commander-in-chief's office of the Fifth War Zone. The office was not big, and he met guests outside and worked on a daily basis inside.

There is also a guard room.

The confidential room was close to the side. When Luo Yao came, he saw Huang Xuecun. He did not have an independent office, but instead squeezed into the same office with several people.

It can be seen that the conditions here are not very good.

After Luo Yao came in, he saluted Li Delin and immediately gave Li Delin a detailed report on the discovery and analysis of the 401 team.

When Li Delin heard this, his face immediately became serious. What Luo Yao said was the intelligence department of the Fifth War Zone could do.

However, if your own intelligence system fails to discover it, or does not have this awareness, this is revealing the gap.

They are professionally doing this, and there are first-class talents, which are incomparable to the Five War Zones.

Luo Yao had no chance of lying to himself in this matter, and there was no benefit. At most, he would just talk about the problem more seriously.

There is a saying in the military strategy: If you think that the enemy is broad, you will have many chances of victory.

If you despise your opponent or underestimate the situation, you will suffer a great loss. What Luo Yao said is not completely unreasonable.

If the Japanese army really had done a secret change of the secret code before the war started, whether intentionally or unintentionally, this was obviously a lesson learned from the last battle in Xiangcheng.

I will change the password myself first. Even if you find it, it will take time to decipher. When you decipher it, the battle will be over long ago.

This is a possibility.

There is also a second possibility. The Japanese army already knew that the Kuomintang had deciphered his secret code. Before the war started, they continued to use the previous secret code to confuse the other party, while secretly changing the secret code and adjusting the deployment. If the Japanese army deciphered his secret code, the consequences would be the most serious.

Think about everything in the worst direction.
