Late at night, Professor Zhang, Liu Zifeng, and Xiangyun gathered in the dark room on the second floor of the "Beautiful" photo studio to study intelligence on the enemy.

"Let me introduce you first," Professor Zhang pointed to them and said: This is Comrade Liu Zifeng of the Xiamen Provisional Work Committee, and this is Comrade Xiangyun, an underground party member in Xiamen.

Liu Zifeng and Xiangyun shook hands tightly.

Professor Zhang asked Liu Zifeng: How long is there until the "Sea Breeze" telegram is received?

Liu Zifeng looked at his watch: It's 11:20, and there are still 10 minutes left.

Professor Zhang said: Take advantage of this time to ask Comrade Xiangyun to report a suspicious situation.

Xiang Yun straightened his thoughts and said: "These days, we have been monitoring the radio station of the Japanese consulate and the puppet Xiamen city government. According to the "Southeast" intelligence, Uchida is a veteran Japanese spy lurking in Xiamen, codenamed "Blue Wolf", and has close ties with Sawashigenobu, the South China intelligence minister of the Japan East Asia Co-Prosperity Association, so I focused my surveillance on the Japanese Consulate General. Important information from the consulate is transmitted through Radio No. 3, which goes directly to Consul General Uchida. In the monitoring of the other party's radio station No. 3, I noticed a strange phenomenon. The station's three telegrams transmitted the same content, and all of them were sent in the wee hours of the night.

Liu Zifeng listened and recorded quickly in the small book, and from time to time marked the key points and doubts.

After Xiangyun finished speaking, Liu Zifeng kept asking: "Are you sure that this person sent the same telegram three times?" ”

"The messages have not been deciphered, but I am sure they are all the same telegram." Xiangyun said as he handed over the telegram.

"The three telegrams sent by the other party are all using the 17.8MC frequency?" Liu Zifeng asked again.

"Yes!" Xiangyun replied with affirmative evidence.

"Strange, this frequency is rarely used?" Liu Zifeng pondered for a moment and then asked, "Is the No. 3 operator male or female?" ”

"It is understood that it is a woman!" Xiangyun said.

Liu Zifeng asked again: "What about the time of the three reports?" ”

"Once in the morning, twice in the early hours of the night." Xiangyun replied.

Liu Zifeng pondered: "It seems that the time of this person's message is deliberately chosen, and the frequency is also carefully selected, short-wave transmission, which is suitable for remote calling and listening." In the early morning and at night, the sound of radio waves is especially clear. The content of the telegram may not have much substance, and the other party is trying to get our attention. ”

Professor Zhang nodded: "I agree with Zifeng's analysis. ”

Liu Zifeng asked: "Is there anything special about the other party's fingering?" ”

"The fingering is smooth, decent, like a trained one, not like an amateur reporter. However, the interval between the reports was too hurried, and it seemed a little nervous. Xiangyun replied fluently.

Liu Zifeng asked again: "What is the severity of the button?" ”

Xiangyun thought for a while: "The fingering is too heavy, and I feel that it is a man who sent the report." ”

Liu Zifeng picked up the message again and looked at it, it was very short, and it was some lifeless Arabic numerals. He stared at the telegram and fell into deep thought.

Xiangyun explained: "After I received the message, I tried to decipher it, and I tried almost all the methods I might have tried. First of all, he applied the known passwords, and tried all the old and new passwords of the enemy, us, and friends that he had at hand in recent years, and even tried the Kuomintang passwords that he had deciphered during the Red Army period, but he still failed to open the lock. ”

Xiangyun said this, and suddenly took out a delicate small notebook from his underwear pocket like a trick and said: I patronized the report just now, and I almost forgot about it, this is a code book of the Japanese puppet army, which was obtained from the puppet city government, and I will give it to you, I think it should be helpful for you to decipher the Japanese pseudo code in the future.

Liu Zifeng took the codebook and looked very excited. He immediately flipped through it and said gratefully: "Priceless treasure, send charcoal in the snow!" ”

Professor Zhang looked at his watch and said, "Get ready, receive the telegram immediately."

Xiangyun turned on the radio, put on headphones, twisted the FM knob, and turned on the frequency of "Sea Breeze".

There was a mess of voices on the radio, and after a while, the sound of the radio became regular.

Xiangyun turned his head and said, "It's connected." ”

In less than 10 seconds, the "sea breeze" sent a message, and Xiangyun quickly copied it, and the two people next to him held their breath and did not dare to come out.

Soon, Xiangyun copied the last set of messages, translated them and handed them to Professor Zhang.

Professor Zhang picked up the telegram and said, "'Haifeng' said that a Japanese puppet 'sightseeing' cruise ship will depart from Taiwan in the near future, pass through the Taiwan Strait, and arrive in Xiamen three days later. ”

Liu Zifeng said: "This is a very important piece of information, and we have to think of ways to stop them." ”

Professor Zhang continued: "'Haifeng' also said that there are members of the Japanese Anti-War League in the Japanese organization in Xiamen, and asked us to find a way to contact him as soon as possible. ”

Liu Zifeng pondered and said: If I guessed correctly, this person who used Radio No. 3 to send a report may be the Japanese Anti-War League number that "Hai Feng" asked us to find.

"If only that were the case." Professor Zhang paused and said: Continue to closely monitor Radio No. 3.

Xiangyun nodded and said: If there is nothing else, I will go back!

Professor Zhang: "Okay, please take care! ”

The two got up to say goodbye to Xiangyun.
