moat!

Naturally, Tianfu would not stand in the river and monitor the dead mailbox. He is not a river god.

But he could look at Kunlu Temple from the buildings on the river bank. It happened that there were several high-rise buildings on the east bank of the moat, and he could clearly see the east wall of Kunlu Temple where the dead mail box was located.

Central Hospital.

Department of Health.

Construction Committee.

Yixianqiao Electric Light Factory.

A bright light flashed in Zuo Zhong's eyes. Tianfu must be hiding in these four places. Every time he released information, he monitored Min Ping's every move from a distance to confirm safety.

The other party may not necessarily work in these places, but he must be able to come and go freely. This is the prerequisite for long-term surveillance. Otherwise, he will arouse the suspicion of people around him and face the risk of exposure.

You must know that the Department of Health and the Construction Committee are government agencies, with guards at the gates and inside, and even agents from the secret service headquarters. It is very difficult for him to conduct surveillance quietly.

Unless he is a senior official of these two agencies and has an independent office, the secret messages sent by the Nandou Group rarely contain information related to the health and transportation construction of the Republic of China.

Assuming for the moment that this is not Tianfu deliberately hiding its own information, then it is unlikely that this person is lurking in these two agencies. How can there be a spy who ignores the information in front of him?

At the same time, a senior official can serve as a lurking mole, but is not suitable as a commander, because when he reaches a certain position, time no longer belongs to him and he cannot move freely.

For example, the Nandou team is preparing to carry out a task. At that time, Tianfu, a senior official, has to attend a meeting. His unexcused absence will definitely attract unnecessary attention.

Once or twice is fine, but if it happens more often, you can't tell whether other people will be suspicious, but a secret agent listening in the corner will definitely be suspicious. After all, there are no Fruit Party officials who don't love meetings.

Combining these circumstances, the only hidden places in Tianfu are the lamp factory and the hospital.

The only people who can freely come and go in the electric lighting factory are the senior management, workers, and merchants of the lamp factory. The first thing that can be excluded is the merchants. The frequency of information release is once every three days, and there are no such merchants.

The lamp factory sells light bulbs. No matter how good the business is, there is no need to run three times a week. The Japanese intelligence agency does not have so much money to waste, so there is no need to buy a warehouse of light bulbs for surveillance.

Zuo Zhong made a simple measurement and found that the Yixianqiao Electric Light Factory is located southeast of the mailbox, almost 250 meters away. If you want to see a person's movements clearly at this distance, you must use a telescope.

Making light bulbs does not require this. Workers have no opportunity and no suitable place to use telescopes. So if you exclude the workers, then only the top management of the lamp factory will be there. Will Tianfu be a businessman?

This is possible.

You have free time, you can contact people from all walks of life, you can easily hide your working capital, and you have the conditions to live in an independent residence. There is no more suitable job to cover than this, but here is the problem.

With Tianfu's caution, he would not choose a cover job that looked like a spy, at least it was unlikely. Zuo Zhong hesitated for a moment and wrote the word "businessman" on the paper and drew a question mark.

It is worth checking this line. The Yixianqiao Electric Light Factory was built by a few wealthy businessmen. The management is all external managers. There are not many people. It is not too difficult to find out the details of these people.

"There is light."

Zuo Zhong looked at Gui Youguang: "Go and check the Yixianqiao Electric Light Factory immediately, especially the senior management of the factory. Also check the Central Hospital. I want to know the background of the personnel and the general layout.

In addition, find a reliable surveillance point nearby. You must be able to see the east wall of Kunlu Temple. You must keep it secret. Even if you give up the mission, you can't alert the Japanese spies. Do you hear me?"

"Okay, Section Chief."

Gui Youguang, who had been idle for a long time, his eyes lit up and he hurriedly ran out. It was just right to leave the basic investigation work to him. After working in intelligence work for so long, he still had this ability.

Zuo Zhong watched this guy leave, laughing to himself, and sent the bald man to check out the Yixianqiao Electric Light Factory and the Central Hospital, so that he would not be like Mrs. Xianglin, mumbling about tasks in his ears every day.

The only problem is that the Central Hospital is not easy to find. As the largest and most well-equipped national hospital in the Republic of China, countless patients come from all over the country for treatment every day.

He had lived here for many days during the Safe Point shooting incident, and poached Ling Sanping by the way. He had a relatively good understanding of the situation at the Central Hospital, and what impressed him most was the beds in the corridor.

Not counting short-term hospitalized patients, the number of long-term patients and their families who are treated there remains at more than a thousand all year round. These people have complex backgrounds and origins all over the country, making it impossible to investigate.

Besides, the hospital is not a critical department. As long as you can afford it, you can stay in the hospital every day, let alone three times a week, even if no one comes in three times a day. It's just that it can easily arouse suspicion.

Zuo Zhong stood up straight and stretched, looking down at the map and lost in thought.

The Central Hospital is located due east of Kunlu Temple, 400 meters apart. Monitoring also requires the use of tools, but unlike other places, there are many places in the hospital that can overlook the other side of the river.

First of all, the entire hospital is four stories high, with a building area of ​​several thousand square meters. In such a large place, surveillance can be done anywhere, and with so many patients, how can we target each other?

This does not include the hospital staff. The Central Hospital has two major departments: internal medicine and external medicine, and has jurisdiction over 16 departments including pediatrics, dermatology and tuberculosis, orthopedics, otolaryngology, and encephalology.

The total number of doctors and nurses inside is probably more than 200. If we investigate one by one, it will take forever to find out. We must find a way to narrow down the scope of suspicion. Zuo Zhong rubbed his head.

I thought about it for a long time.

He slapped his thigh suddenly, hurried back to the office with the map and confession, picked up the phone on the table and dialed: "Hey, please call me the director's office of Renxin Hospital, yes, hurry." Gu.

Zuo Zhong felt that he was really stupid. He should have called for an expert like Ling Sanping a long time ago. Although this guy left the Central Hospital, he still had many classmates and friends working there.

Based on the other party's knowledge of the hospital, there must be a way to narrow down the scope of suspects. If not, then spit out hundreds of thousands of medical equipment expenses, md, his small coffers will be empty.

"Hello~ who's there?"

Ling Sanping's voice sounded on the other end of the phone.

"It's me, come to my office."

Zuo Zhong became angrier the more he thought about it, and his face turned black.

"Oh, okay."

After two simple words, Ling Sanping became silent. Zuo Zhong looked at the phone in disbelief. It was outrageous. Except for making a phone call to ask for funds, he couldn't even see a shadow at other times.

Are you using him as a wallet? But even if it is a wallet, you should say thank you every time you take the money instead of running away after taking the money. Isn't this a phone scam? It's simply unreasonable.

If it weren't for the canned plan that was going on and needed this guy's plastic surgery skills, I would have sent this bastard with no superiority or inferiority to the Northeast to become a pair of desperate mandarin ducks with Xiao Qingmin.

After Zuo Zhong finished complaining about Ling Sanping, he was flipping through the information about the Central Hospital and familiarizing himself with the map, until half an hour later there was a knock on the office door and He Yijun's voice came from outside the room.

"Section Chief, Dean Ling is here."

"Let him in."

After Zuo Zhong finished speaking, he raised his head and put the map aside. He happened to see Ling Sanping walking into the office. He was still as graceful as ever, but he was a little haggard. He might have just had surgery.

There are too few doctors in Renxin Hospital who can perform plastic surgery. Ling Sanping is the main surgeon for the canned surgery, and the others can do auxiliary work at most. The more tired he is, the smoother the canned plan will be.

"Here you go, sit down."

Zuo Zhong glanced at him: "I came to you because I need your opinion on a case. I suspect there is a spy in the Central Hospital. It may be a staff member, or a patient or family member.

There are no clues so far. The other party may have an independent space, can use telescopes at any time, and can freely come and go in the hospital for a long time without arousing suspicion from others.

These are some speculations on my part. They are not very accurate and can only be used as a reference. You have been in the Central Hospital for so many years, can you help me think about who the other party is, a patient or a doctor."

Ling San lay flat on the chair, his eyebrows tightened: "It's really difficult for me to be sure based on these alone. Section Chief, you should also know that the Central Hospital is very large and there are many people coming and going."

"Yes, look at the map again. The opponent is lurking in the Central Hospital with the purpose of monitoring Kunlu Temple on the other side of the moat. Do you have any ideas based on your memory?" Zuo Zhong pushed the map to him.

Ling Sanping took the map and looked at it. He slowly closed his eyes and recalled the hidden places in the hospital where he could see Kunlu Temple. This could only be done if he was very familiar with the hospital's terrain.

His legs swayed rhythmically, and after five or six minutes, he opened his eyes: "Only the third and fourth floors of the hospital can see Kunlu Temple, and other locations will be blocked by the cedar forest behind the building.

Among them, there are dentistry, obstetrics and gynecology on the third floor, and a baby room and its ancillary facilities. The fourth floor is a third-class ward. The ward is a large room with 25 beds in each room. The nurse's desk is located at the door of the ward."

"Odori Room?"

Zuo Zhong didn't expect this to happen. At that time, he was hospitalized on the first floor, and there were two people in a room. If Tianfu was a patient, it would be safe to monitor him in this environment. At worst, he would have to lock the door.

But there are 25 beds in one room, let alone taking out a telescope to monitor, even if you fart, you can hear it in the whole room. After all, I have been a little out of touch with the people recently.

Ling Sanping didn't know that his immediate boss was having random thoughts, so he nodded.

"Yes, if other factors are not considered, I still think that the other party is a patient. If the ward cannot be monitored, he can go to the toilet. There is a window on the west wall of the toilet, and you can clearly see the other side of the river.

As for doctors and nurses, the possibility is not very high. The main reason is that the working hours are not fixed, they often need to work overtime, and they are easily discovered if they are away for too long, which is not conducive to intelligence activities.

But nothing is absolute. For example, the dentists on the third floor are very free. They use an appointment system for medical treatment. They can come and leave when they want. The hospital won't say much, well, that's all."

Zuo Zhong was a little helpless, so he said that the scope of suspects was defined as the doctors and patients who haunted the third and fourth floors. This was as if he hadn't said anything. The hospital was not a military base, and anyone could go upstairs.

As for squatting in the toilet, don't treat the spy as a fool. Not to mention whether the other party is spying on the other side in the toilet. Even if he is, there must be corresponding countermeasures. This is too risky.

He thought for a while and asked: "Why does the hospital ignore those dentists? Even if there are not many patients or it is an appointment system, normal rules and regulations must be followed. Is there any special situation here?"

"That's right."

Ling Sanping lazily twisted his neck: "Many big shots don't want to go to the hospital for dental treatment, so they invite doctors to their homes. The hospital can't afford to offend those people, so they simply turn a blind eye."

"oh."

Zuo Zhong was thoughtful, then picked up the phone and called the interrogation room: "Chunyang, take people to conduct surveillance near Min Ping's residence in the early morning, bring more film, and start taking photos of all pedestrians from tomorrow morning.

I will go there early tomorrow morning and I have some new situations to inform you. Please be careful when taking action. The opponent this time is very cunning and vigilant. If anything goes wrong, this clue will be cut off."
