After a night of silence, Chu Lingyun asked Ni Loach to go to the post office to get information early the next morning.
The post office is located on Pengliu Yang Road, which can be said to be very close to them. They are both on the same street, only more than a hundred meters apart. In many operations, people from the Military Intelligence Department will pass by the post office.
Fortunately, the Military Intelligence Office is an intelligence unit and usually pays great attention to confidentiality. Most people have no interaction with the surrounding positions.
But there is one exception, and that is Loach.
Loach is usually very active and often runs out. He has been to several nearby units, including the post office. This time he had to be used when he went to the post office to inquire about information. Chu Lingyun simply put makeup on him and turned him into another person.
Look.
"Team leader, let me ask clearly. There are more than a dozen people in the post office who receive letters in the mailbox. Their area will collect all the letters in the mailbox after 5 pm every day, and then hand them over to the sorting team."
Loach is very flexible, even if he tries to find out information from a strange face, he can still find out clearly.
There are four people in the sorting class, and they sort all the letters received in the city every day. These letters will be sorted according to addresses, and then packaged and sent to all parts of the country.
"I asked specifically that the people in the sorting class have a rotation system, but there is one person who never takes a break. This person's name is Lao Li Tou. He is a mute bachelor. Because he can't speak, he usually has few friends. He does his job every day. He works at the post office.
Have been working for more than 20 years.”
Loach continued to report, while Chu Lingyun quickly analyzed it in his mind.
To ensure that urgent contact letters can be discovered at any time, one must keep an eye on these letters every day. The mute old Li Tou is a serious suspect. Only he sorts these letters every day and can ensure that the letters sent by Hanako Abe are discovered.
However, Lao Litou's life experience is clear and he has worked in the post office for such a long time. The possibility that he is a spy is extremely small, and the most likely person is someone who was bribed by a spy.
"In addition, the sorting team sorts all the letters in the city. Whether they are letters returned from the mailbox or letters delivered from the business offices, they will be sorted by their hands. In addition, I also asked, there are some business offices
Letters will be delivered the next morning, and only letters in the mailbox will be delivered to the post office that evening."
Loach continued, Chu Lingyun understands why Hanako Abe is required to send letters through the mailbox. Some letters sent at the counter will not be delivered until the next day. In this way, it is very likely that they will not be found, or they will be found very late, delaying their emergency.
Connector.
"You continue to check how many other people they have who may have access to all the letters. In addition, you should also investigate Lao Litou's living habits and family background clearly."
Chu Lingyun once again ordered Ni Loach that Lao Li Tou had serious suspicions and needed to be kept on top of him, but the investigation against him would not stop.
"Yes, team leader, I'll go right away."
Loach accepted the order and left, and was very happy when he left. He had made great contributions to the arrest of Watanabe Ichiro, and later made great contributions to the arrest of Asaou Ono, so he was promoted to a second lieutenant and became a squad leader.
Now, she caught this bastard, Hanako Abe, and although she got it by luck, the credit really fell on him.
If he can make more contributions, even if he cannot be promoted to military rank, he will most likely take over the position of squadron leader after Chu Lingyun is promoted.
Now everyone in the station understands that the future leader of the action team must be Chu Lingyun.
As a direct descendant of Chu Lingyun, he will naturally have a great chance of being promoted as a commander once he is promoted. He will work hard to make meritorious deeds for his own future, otherwise there will be no reason to promote him.
After Loach left, Chu Lingyun took out some information and looked through it carefully.
This is the roster of the Hankou Post Office. All the members' information is in it. I asked for it from the post office in the morning. People from the Military Intelligence Department asked them for something, but they didn't dare not give it.
Not only must it be given, but it must also be kept secret and not allowed to be known to anyone.
In this era, the post office is considered a better unit, but its benefits are limited. People in the post office can only take care of food and clothing. If the family has more mouths, their salary may not be able to support the whole family.
Old Li Tou is a serious suspect, but Chu Lingyun will not miss the others and must investigate them all.
After Ni Loach's report, Chu Lingyun had a hunch that this old Li Tou was not the person he was looking for, or in other words, not the person he was looking for in the end.
Old Li Tou is too obvious. Once someone figures out this emergency contact method, Old Li Tou will definitely be listed as the first suspect.
If it had been anyone else, it would have been possible to arrest Lao Litou directly for interrogation.
Chu Lingyun had suffered losses from Yang Jian and knew very well how cunning Japanese spies were. They would not leave such a big loophole for people to understand their arrangements at a glance.
However, even if Old Li Tou knew nothing about Japanese spies, he must have played a very important role in the arrangement of Japanese spies.
The reason is simple. Only he can see all the letters collected in the mailbox every day, ensuring that Abe Hanako's emergency notification method can be discovered.
So we can only stare at him, but not arrest him.
After looking at the list for a while, Chu Lingyun closed the information. He couldn't find any useful clues from the information alone. In the end, he still had to look at the investigation results of Ni Loach.
Chu Lingyun sat on the chair, closed her eyes and rested.
He was thinking, if he were Du Juan, how to arrange a seamless way to know Hanako Abe's emergency contact without being noticed by anyone.
First of all, you cannot directly bribe Lao Li Tou, otherwise Lao Li Tou will become an insider. Once he is exposed, you will be in danger.
But the appearance of this letter must be confirmed through Lao Li Tou.
Since he didn't come forward and wanted Lao Li Tou to notify him, Chu Lingyun opened his eyes and thought of a possibility.
As long as there are multiple ties between Du Juan and Lao Li Tou, these can be achieved. This bond is the key, which can not only allow Du Juan to get the news, but also not put him in any danger.
Chu Lingyun is not sure yet what this bond is. It may be a person, it may be an object, or it may even be one thing.
For example, after Lao Li Tou discovered the letter, he did something special, so that Du Juan could use this matter to confirm that Abe Hanako contacted her urgently.
Chu Lingyun didn't know if his guess was correct, but if it were him, he would do this to ensure that he was foolproof.
At noon, the loach hurried back.
When he arrived at Chu Lingyun's office, he reported immediately despite sweating profusely: "Team leader, we have found out everything. Old Li Tou originally had a mother who died of illness three years ago. Now he is the only one in the family. It can be said that he has no relatives or friends.
. He is mute and has no friends in the post office. Only Li Zheng from the boiler room has a good relationship with him. It is said that the two are somewhat related, as if they are branches of the same family."
