The police stations in the three suspicious areas have all received orders from the Police Department, requiring them to register the population within their jurisdiction and cooperate with the Department of Police to send personnel for verification.

This order came a bit suddenly, but it was not a big problem. Even the Jinling Police Department could not say anything. This itself was the responsibility of the Police Department.

The patrol officers went door-to-door to register the population, including name, gender, age, education level, occupation, migration, marriage, birth, death, and housing situation.

Even photos and fingerprints must be kept on file. This was Zuo Zhong's decision. It just happened to be a small-scale trial of population registration. With this information, it will be very helpful for future counterintelligence work.

He spent a long time on this matter with Dai Chunfeng and applied for a batch of special funds to purchase cameras, photo paper, and processing fees. Dai Chunfeng was very interested in this and asked Zuo Zhong to complete it as soon as possible.

When the police station receives a piece of information, the special agents of the Intelligence Division will check it, and three people will check it at the same time, to avoid anyone taking advantage of troubled waters. Finally, all the information on suspicious persons will be summarized and submitted to Zuo Zhong, who will decide whether to follow up.

There are many spies in the Intelligence Section who want to make meritorious deeds.

Ban Jun led a group of anti-smuggling policemen to check everywhere, especially those new shops. After entering the store, Ban Jun first apologized with a smile and arranged for others to check the goods list, while he himself drank tea and chatted with the boss.

.

He doesn't blackmail or extort money. He has a good attitude and the backstage of the store is hard to say.

Ban Jun is a veteran in the army. He can survive the mountains of corpses and seas of blood. He is a shrewd person. In addition, he has been an anti-smuggling policeman for so long. He has a keener eye for people and things than ordinary spies. He often pulls the strings with just a few words.

Despite what the other party said, I checked dozens of shops and found nothing unusual.

Zuo Zhong was not in a hurry, intelligence work was just like that, especially when faced with professional agents in the special work class, the first thing to compete with was patience.

Moreover, the house inspections have been very fruitful in the past few days. A total of more than 30 suspicious persons have been found. It is unlikely that these people are all Japanese spies, but they are still valuable for in-depth investigation.

Zuo Zhong has already informed the underground party, so these suspicious persons will not be his own. They may be members of warlords from various places, or members of Jianghu society. In short, they are not good people.

Just kill all the rabbits and give the people of Jinling a clear future. As for evidence, does the Secret Service need evidence to do its work?

In addition, the equipment of the Telecommunications Branch did not stop searching, even with impressive accuracy.

Zuo Zhong wanted to see the reactions of the three radio stations to the police station's actions. If the other radio stations had no reaction to the police actions, it meant that Zuo Zhong's scope was wrong, and the direction of the investigation should be adjusted in time.

"Section Chief, the three radio stations have been silent these days. It should be that the patrol police's actions shocked them." Gu Qi reported the feedback from the Telecommunications Section to Zuo Zhong.

Zuo Zhong put down the pen in his hand: "You tell the police station and the anti-smuggling division to be careful not to ask questions that are not related to their work. Leave professional matters to us. The Japanese will not run away."

He is not afraid of these Japanese spies evacuating Jinling. The Japanese have finally managed to lurk them, spending a lot of energy and money. They must be prepared to use them for a long time. This will be a protracted war.

The facts turned out to be as Zuo Zhong expected. He probably thought that population registration was a normal operation of the police station. After a few days, the three radio stations gradually became active again, and even the time they were on increased.

Zuo Zhong was not angry. It was good for him to be so high-profile. If the Japanese really had to stay dormant for a long time, it would be difficult for the intelligence department to lock the target.

By the time the residents in the three suspicious areas were identified, half a month had passed. The Intelligence Section had arrested more than 100 suspicious persons, but not a single Japanese spy.

Most of these more than a hundred people were gangsters and gangsters. Under severe torture, they confessed and verified hundreds of cases, all of which were serious cases such as murder, robbery, and fraud.

Zuo Zhong looked down on these cases and assigned them to the police station. This made Xing Hanliang very popular in the Police Department. It is said that the director personally received him.

But the Japanese spy failed to solve the problem, so Xu Enzeng said a lot of weird words, and Director Chen called Dai Chunfeng to "encourage" him.

After Dai Chunfeng came back, he called Zuo Zhong to the office and said seriously: "Shen Zhong, many people are saying that our Secret Service has become a police station. You have to act as soon as possible."

Zuo Zhong understood his difficulty. Both his teammates and his boss asked him to catch up, and quickly assured him: "Teacher, the students here are working hard, and there will be results soon."

Dai Chunfeng did not smoke, so he threw Zuo Zhong a box of cigars given by others. He was still very confident about Zuo Zhong's abilities and asked Zuo Zhong to talk, mainly to vent his unhappiness.

The secret service headquarters has done so many things, and even let the underground party go. Director Chen never said anything. The secret service has done so much work, but the detection time has been a little longer, and it has been trained like a grandson. Old Dai is tired.

.

Zuo Chong returned to his office and looked at the large amount of population information. He knew that the Japanese spies were hiding in it, but they were well hidden.

The phone rang, and it was Ban Jun calling: "Zuo Zhong, I haven't gained much from this, but your people have taken back all the store information. Alas, I originally wanted to help you, but..."

Zuo Zhong sat on the chair, laughed and comforted him: "Old Ban, you have helped me a lot. In my job, I have to find clues from thousands of clues, and it cannot be so fast."

After chatting with Ban Jun for a few more words, Zuo Zhong hung up the phone. He had expected that he could not find out, but the collection of basic information was indispensable. Now the permanent residents of the three suspicious areas have been known. Their appearance.

Fingerprints and relationships were all in the hands of the Intelligence Department, and Zuo Zhong felt that he could proceed to the next step.

Japanese spies are hidden among the people, so we can identify them. The specific method is to use the power outage that the Telecommunications Division once used, but Zuo Zhong's plan is more accurate.

Zuo Zhong called to Gu Qi: "Lao Gu, you have people cut off the power starting tonight."

Gu Qi's face was full of doubts: "Section Chief, the Telecommunications Department has tried this before, but it didn't work."

Zuo Zhong pointed to a bunch of population information: "Only stop at the streets where these people live. Their occupations are in line with our predictions. Their working hours are free, their income is not low, and they live in a single family home."

Gu Qi still didn't understand. Zuo Zhong himself said that the Japanese spy's radio station had batteries and flashlights. According to these information, although the scope of the power outage could be reduced, it was still meaningless.

Zuo Zhong could only tell him clearly: "When there is a power outage, Japanese people can indeed use batteries and flashlights, but they always have to charge the batteries, right?"

Gu Qi seemed to understand: "Chief, are you telling us to check whose household has abnormal electricity consumption and buy batteries?"

"There may be backup batteries, and oil lamps and candles can also be used for lighting."

Zuo Zhong clenched his fist: "But you can't generate your own electricity, right? In all suspicious streets, first secretly record the daily electricity consumption of residents, record it for several more days, and find an average.

Wait for the other party's radio station to cut off the power immediately when it is in use, and see whose power consumption increases after the power is restored. You can do it a few more times. If the power consumption increases multiple times, there must be something wrong!"

Gu Qi thought about it for a while and asked: "It is better to check the power directly. When the radio is in use, it will also consume more power. It must be more than the people's homes nearby."

Zuo Zhong reminded him: "Japanese spies are not fools. They will definitely find ways to cover up, such as electric stoves or multiple electric lights. Only by forcing them to overuse the batteries can they be easily discovered."

"Yes!" Gu Qi stood at attention and went out with a smile on his face.

With the direction of the investigation, the rest is just a matter of time and effort. The agents, wearing the uniforms of the Electricity Bureau, shuttled through the streets and alleys, recording in detail the daily electricity consumption of some households.

There are a lot of electricity thefts these days, and the electricity bureau’s inspections are very common. People don’t think anything is wrong. They just feel that the government is too messy, not only to register but also to check electricity.

If you want to see the problem from the power consumption, you need to record the data for a long time, so even if the spy radio communicated frequently during this period, Zuo Zhong didn't care about it, just think that they were the last to go crazy.

On this day, in Jinling Wenchang Alley, the "blue-headed fly" from the Electricity Bureau inspecting the circuit came again and started to quarrel with others. The residents in the alley had nothing to do and ran out to watch the fun.

Wenchang Lane is named after the nearby Wenchang Palace. Wenchang is also known as Wenquxing and Wenxing. It is the god who dominates fame and fortune in Chinese mythology. Ancient scholars were very concerned about this auspicious omen.

In fact, not only in ancient times, the imperial examinations ended many years ago, but the residents of Wenchang Lane are also all kinds of scholars engaged in literary work, such as clerks in nearby government offices and teachers in schools.

Wu Chunyang wore a dark green hat and rode his bicycle crookedly into the alley. As soon as he entered, he was stopped by a few old men.

He seemed to be frightened. He put one foot on the ground and shouted to the old men: "Hey, uncle, be careful, don't hit you."

Several old men grabbed the bicycle faucet, and one of them shouted angrily: "Good boy, I finally caught you, pay for it!"

Wu Chunyang was helpless. Wenchang Lane was a key suspect area, so Zuo Zhong sent him over to investigate. As a result, these old men claimed that the electricity at the electricity bureau was unstable and broke their lights. They pestered him for compensation. They really thought he was

He was taken advantage of.

Wu Chunyang took off his hat and said with a wry smile: "Uncle, if you have something to do, you have to go to the bureau and tell me. I'm just a patrolman. It's useless for you to tell me."

Several uncles refused to let him go, and the residents around him talked about the high electricity bills and frequent power outages from the electricity bureau.

The fussing around made Wu Chunyang anxious, so he simply threw the bicycle and sat on the ground, letting them say nothing and acting like a rogue.

The elders were speechless by his move. They were scholars and had no problem arguing with others, but they could only stare at the scoundrels.

Fortunately, at this time, an enthusiastic person came to break up the fight: "Don't worry, everyone, it's really useless to look for him. If he was really capable, he wouldn't come out to patrol."

Wu Chunyang got up and said, "Yes, what this gentleman said is reasonable. I only get more than ten yuan a month, so I really can't care about what you say."

The elders had no choice but to leave muttering about tigers falling flat and being bullied by dogs. Wu Chunyang breathed a sigh of relief. If he continued to pester him, he would delay recording the battery. He thanked the person who broke up the fight: "Thank you, sir. I will help you with your home appliances in the future."

Find me."

The man didn't reply, waved his hand and went back to his yard. It seemed that he didn't want to talk to someone like Wu Chunyang, which was the bad temper of a scholar.
