Zhao Ziliang called, brought Ning Zhiheng to his office, and put the documents in his hand in front of him.

"The situation ahead is becoming more and more tense, the two sides are deploying troops, war is about to break out, yesterday he had already gone to Shanghai to preside over the intelligence work, before he left, he specially instructed that we should speed up the work of detecting Japanese spies, but in the past few days, I still have no clue about the case, it seems that to engage in counterespionage, I still want you to do it, I will not hold on."

Zhao Ziliang has been at a loss for the past few days, and he knows that to deal with Japanese spies, he still has to find Ning Zhiheng, an expert.

This was also expected by Ning Zhiheng, he did not have the slightest politeness and prevarication, took the document and said with a smile: "These little things are still used by the section chief, you are tired, I will definitely arrest the Japanese spy in a short time!" ”

Zhao Ziliang laughed, pointed at Ning Zhiheng and quipped: "You dare to say such things in the entire Military Intelligence Department, but it is true!" ”

He knows that his favorite general has a skill that is difficult for others to detect, which is also the basis for his current position in the Military Intelligence Investigation Department.

He continued: "Now that the department is not here, the work of the Military Intelligence Department is presided over by Deputy Director Huang, he is your backer, you naturally don't have to worry much, and he is usually a careless person, and the specific work will be done by me. ”

Between the words, arrogance was born, and it was obvious that his mentality at this time had changed greatly, and it was far from what it was a year ago.

Ning Zhiheng returned to his office, opened the file, and flipped through it carefully.

It was not long before the start of the war, although Ning Zhiheng did not want to get involved, but as an intelligence officer, what he could do, his duty, he had to do his best, to crack down on the Japanese spy force to the greatest extent, and strive to remove all these hidden dangers before evacuating Nanjing, so as to do his part.

After carefully studying the documents in his hand, Ning Zhiheng leaned back on the chair and closed his eyes in contemplation.

This document is a transcript provided by the Telecommunications Section, which is by far the most advanced telecommunications department in China, and it is able to listen to the signals and radio waves of various radio stations in all urban areas of Nanjing, and record the data at any time for reference.

As the capital of the Republic of China, Nanjing City has many departments, many businesses, military radios, commercial radios, too many to count, and it is very troublesome to manage, just listening to the radio waves is a difficult job.

However, this situation has been alleviated with the re-expansion of the Military Intelligence Investigation Department, which is most concerned about the telecommunications department, and as early as a few years ago, it recruited outstanding mathematicians and telecommunications personnel to form a decipherment team, and a few months ago the expansion of the military intelligence investigation department has purchased a large number of advanced telecommunications equipment, and the telecommunications section has also doubled, so the control over the radio stations in Nanjing has been greatly increased.

In the following years, with continuous investment, the level of the telecommunications department of the Military Intelligence Investigation Department developed rapidly, and soon surpassed that of Japan, which repeatedly performed miraculous feats in the later stage of the Anti-Japanese War, including the credit of Ning Zhiheng's many encrypted codebooks.

This record clearly indicates that the frequency and method of transmitting the radio waves of the four radio stations that suddenly increased in the four areas of the Nanjing city were the old radio stations that had disappeared for three months.

But that's all the telecommunications department can do, they can't pinpoint their exact location, and the time these radio waves are sent for too short a time, and the time of monitoring is too short to detect their patterns.

In addition, Nanjing City has a population of one million, and there are tens of thousands of people in a small city casually, which greatly increases the difficulty of the detection work, and in a short period of time, Zhao Ziliang is also helpless, so he simply threw it to Ning Zhiheng.

Ning Zhiheng opened his eyes, picked up the phone and called Yu Cheng from the Intelligence Department.

"Old Yu, are you free now? Okay, come to me! ”

Yu Cheng naturally didn't dare to slack off on Ning Zhiheng's phone call, in the Military Intelligence Investigation Department, except for a few senior executives, that is, Ning Zhiheng's ruthless character was the most difficult to provoke, so far Ning Zhiheng suddenly appeared in the interrogation room with the hideous face of a killer, which still made Yu Cheng, who was at the scene, feel palpitations when he thought about it.

Not long after, Yu Cheng came to Ning Zhiheng's office.

"Zhiheng, do you have something to look for me?" Yu Cheng asked, and when he entered the door, he was full of smiles.

Ning Zhiheng got up and invited him to sit down on the sofa, and then handed the document in his hand to him.

Yu Cheng hurriedly opened the document and flipped through it carefully, and then asked Ning Zhiheng: "This is the monitoring record of the radio waves, what do you want to know?" I know it all! ”

Ning Zhiheng opened his mouth and asked: "The telecommunications department mentioned in the document that the frequency and method of one of the radio waves are very familiar, and it was a case that your intelligence department was handling at that time, and the object of your investigation was precisely this radio wave frequency.

At that time, it was near the Zhonghua Gate in the south of the city, but then it disappeared, and the radio wave disappeared for a while and then reappeared, in the area of the Black Corridor block in Beicheng District, and disappeared again three months ago, and now it suddenly appeared again, and the location has also become near the paint factory. ”

Speaking of this, Ning Zhiheng looked at Yu Cheng and asked in a light tone: "The record indicates that this case is in charge of you, can you tell me about the case?" ”

Only then did Yu Cheng know why Ning Zhiheng wanted to bring him here, it turned out that he was going to ask about this matter, he couldn't help but smile bitterly and told the matter one by one.

It turned out that in April last year, the intelligence department found a suspicious person, and they continued to monitor for a period of time in line with the idea of casting a long line to catch a big fish.

However, the other party was very cautious, and at the critical time, the tracking personnel missed their whereabouts and were discovered by the other party, so they suddenly fled, and under the pursuit, the suspicious person was killed, and the clue was cut off.

However, the intelligence section is not a vegetarian, and after analysis, it is believed that the upper line is hidden near the Zhonghua Gate, but the area of the Zhonghua Gate is too large and densely populated, and it is impossible to determine the target.

They judged that the upline was very likely to be a carrier pigeon, that is, the leader of the intelligence team that controlled the radio station, so they called in the telecommunications department to guard the Zhonghuamen area to listen day and night.

Because during that period, the Military Intelligence Investigation Department was helpless against Japanese spies, and it was rare to find a clue this time, Gu Zhengqi gave a death order, and he must make every effort to solve the case, so Yu Cheng took a large number of people and telecommunications personnel to squat for two months, and spent a great deal of money to finally master the law of this radio wave, find a more specific location, and narrow the target range to the vicinity of Bell Lane in Zhonghuamen District.

That night, when they were about to send a report to the other party again, they suddenly launched a large-scale search for Bell Lane, thinking that they would have all the stolen goods.

The radio signal suddenly disappeared that night, and Yu Cheng had no choice but to continue the search as planned, and searched the entire fifty-eight households in Bell Alley from bottom to bottom, almost every household, inch by inch, but found nothing.

The operation, which took two months and cost a lot of manpower and material resources, finally failed, so the Intelligence Section was greatly disappointed, and Yu Cheng, who carried out this task, was naturally discouraged, and there was no follow-up.

Ning Zhiheng heard this, thought for a while and asked: "In other words, this carrier pigeon should be a resident of Bell Lane, but he suddenly gave up sending the report on the day of the report, could he have noticed your reconnaissance action?" ”

Yu Cheng spread his hands and said helplessly: "I don't know!" Perhaps it was discovered that our actions were discovered, and according to the law of the radio waves that we had previously monitored, there must have been a report that night, and we judged that it was a security signal from the Japanese spy team, and it was sent once every ten days, and each time it was around eleven o'clock at night.

The arrest at this time can ensure the location of the Japanese spy who was sending the report at that time, that is, he must have been in Bell Alley at that time, but if there was no report that day, we cannot be sure whether the target was in Bell Alley at that time.

In fact, the search turned out to be the same, and nothing was found. ”

Ning Zhiheng asked again: "After that, there was no investigation of the people in Bell Alley?" ”

"I have investigated, but there is no basis, and there are no conditions for screening, there are 58 households in the entire Bell Lane, with a population of more than 200, how can I have so much energy to investigate and track, this is impossible to do."

What Yu Cheng said is indeed the truth, it takes a lot of manpower and material resources to follow up and investigate a person, and it is simply impossible to follow up and investigate more than 200 people in one go.

"Were all the people in Bell Alley there at the time of the search? Was there a case where someone left that night? Ning Zhiheng asked.

"All the people were there, and we went door-to-door with the household registration police, and it was late at night, and all the people were resting in their own homes." Yu Cheng replied.

Ning Zhiheng thought about it carefully, and still felt that the other party should be a resident in Ringing Alley, but he was aware of the actions of the Intelligence Section in advance, and gave up sending the report on the same day, and at the same time transferred the radio station, making all preparations to deal with the search and avoid this crisis.

Ning Zhiheng asked again: "It seems that the other party left Bell Alley later, and then came to the vicinity of the Black Corridor Block, did you think of starting from this aspect to investigate?" Let's investigate, among the more than 200 people in Bell Lane, did anyone move to live in the Black Corridor neighborhood later? ”

Yu Cheng smiled bitterly: "Zhiheng, Nanjing City is the national capital, there are too many floating populations, many people do not have household registration in Nanjing, they are just temporarily registered, and then they disappear." In particular, as long as they forge a certificate and change their identity, they can temporarily rent a house, which is not difficult for Japanese spies. It's so hard to find someone like looking for a needle in a haystack! ”
