Wang Yuemin agrees with Chu Lingyun's point of view, the concession is like a country within a country, and it is indeed impossible for them to let go of their hands and feet, and it is very risky to release Abe Huazi at this time.

"That's a good idea, Ling Yun, I didn't expect you to be so young and act so steadily, it's very rare."

Wang Yuemin was even more satisfied with Chu Lingyun, not arrogant or impatient, no wonder he was able to continuously track down the clues of the Japanese spy and keep catching the Japanese spy.

"Stationmaster, team leader."

As he was talking, Zhong Hui hurriedly ran back from outside, the garden road was not too far away from them, and there was no one on the road at night, Zhong Hui went back and forth very quickly.

Seeing Zhong Hui, Chu Lingyun hurriedly asked, "Have you found the place, what is the situation there?" ”

"I found it, the place is very remote, No. 109 is a private house, and I have arranged for someone to keep an eye on it."

"Be careful when you stare at people, so that no one notices."

Wang Yuemin told that the Japanese spy was cunning, and when he was staring at Yang Jian, he was discovered by the real Japanese spy, and finally let them escape, such a mistake must not have a second time.

"Don't worry, stationmaster, I've arranged it all, and it'll be fine."

Zhong Hui hurriedly replied, Chu Lingyun was frowning, bowing his head and thinking.

Wang Yuemin saw that Chu Lingyun hadn't spoken, and couldn't help asking, "Lingyun, what are you thinking?" ”

"No, we seem to have overlooked a problem."

Chu Lingyun raised his head directly and asked the two of them: "Stationmaster, Zhong Hui, have you ever sent a letter usually, and if you send a letter, how long will it take?" ”

What Chu Lingyun was thinking about just now was the statute of limitations.

Originally, he was thinking about how long it would take for the cuckoo to see the letter after it arrived, but when he thought about it, he suddenly remembered that it would take time to send a letter.

Not to mention now, even in the future, the fastest express delivery in the same city will take a day, unless you are looking for errands. In this era, not to mention, since it is an emergency contact, and the meeting will be met at noon the next day, how can the cuckoo guarantee that the letter sent the day before will be received by him the next day?

Wang Yuemin and Zhong Hui were stunned, and soon, both of them understood why Chu Lingyun asked this.

Zhong Hui shook his head and said, "I don't know if it's sent to the same city, but the letter I send to my hometown usually takes more than ten days to arrive." ”

"I received a letter from the same city, and it took three days to receive it."

Wang Yuemin sat up straight and said solemnly, what he received was a letter from a government department, and it took three days for such a letter, how could the letter sent by the cuckoo be received in one day?

The address for emergency contact is just a disguise.

"Stationmaster, since the letter could not be received in time, and Du Juan used such emergency contact information, then he must have a way to know the existence of the letter before it was sent."

Chu Lingyun said quickly, Wang Yuemin glanced at Zhong Hui, and the two said in unison: "Post office." ”

"That's right, it's the post office, Cuckoo must have planted someone at the post office, otherwise there would not be such an emergency contact information."

Chu Lingyun said firmly, when the daylily is cold when he receives the letter, and he can see it quickly when he sends the letter, there will inevitably be a Japanese spy in the post office.

Otherwise, if you can't see this letter, it's better not to have such an emergency contact information.

"Ling Yun, fortunately you have a flexible brain, we were almost misled, really staring at that No. 109 will make the Japanese spy laugh off his big teeth."

Wang Yuemin said with palpitations, in fact, the loophole of the timeliness of sending letters is not difficult to find, the most terrible thing is that the authorities are confused, if it weren't for Chu Lingyun's quick reaction and thinking of this, he would still be kept in the dark.

"Stationmaster, since we have found out that the cuckoo is really located at the post office, No. 109 doesn't need to do anything to them, and we don't even need to keep an eye on it, so as not to startle the snake."

Chu Lingyun said to Wang Yuemin, and Wang Yuemin nodded: "You're right, give up No. 109, and we will investigate the post office directly." ”

"Zhong Hui, let your people go and inform the brothers who are guarding and retreat, and then you go to the prison and ask Abe Huazi whether her emergency contact information is to send a letter at a fixed location, or anywhere."

"Yes, I'll go."

Zhong Hui led the order and ran out, while Wang Yuemin stood up and kept walking back and forth.

He has a deep understanding of the cunning of Japanese spies, there was Yang Jian before, and there is now No. 109 Huayuan Road to confuse them, and he really has to be cautious to explain to these Japanese spies.

Zhong Hui came back quickly, and immediately said when he entered the office: "Team leader, I asked, Abe Hanako said that any mailbox is fine, I specially asked her again, whether it can only be a mailbox or a mailbox and a counter, and she said that it can only be placed in the mailbox." ”

"Good job, you go and rest first."

After Chu Lingyun finished speaking, he looked at Wang Yuemin, Wang Yuemin continued to walk around, Chu Lingyun understood his habits, Wang Yuemin liked this most when he was thinking about problems.

"The letter can only be sent through the mailbox, not the counter, indicating that the cuckoo confirms the existence of the letter through the mailbox, and if any mailbox can, then it is not a single worker who collects letters from the mailbox on the street, and the person who can find the letter must be at the post office headquarters."

Wang Yuemin quickly analyzed, and Chu Lingyun had thought of the result he said before, but he still stretched out his thumb and said: "Stationmaster Gao Ming, I thought of so much so quickly, I'm still confused." ”

"Haha, you."

Wang Yuemin, who was a sycophant, was very comfortable, he walked back and forth for a while, and said:

"We don't know what happened inside the post office, but there were only a few categories of people who had access to the letter, such as classifiers or receivers. They don't use the counter to send letters, they must be worried that there will be a delay on the counter, or they can't see the letters on the counter, in this case, we just need to investigate who can access the people in these mailboxes, and the scope of the investigation has been narrowed down a lot. ”

"Stationmaster, what you said is so right, with your help from the stationmaster, that cuckoo will definitely be caught by us this time."

Chu Lingyun said with a smile, Wang Yuemin was in a good mood, and his sleepiness disappeared a lot.

"It's a pity that it's too late now, so I can only investigate tomorrow."

Wang Yuemin said regretfully, it was already more than twelve o'clock in the evening, and the time was indeed very late.

"Don't worry, tomorrow I will definitely investigate all the suspects in the post office."

Chu Lingyun stood up straight, and his attitude made Wang Yuemin appreciate it very much.

"Lingyun, you have to be busy tomorrow, go back early and rest, let your people rest too, there is still a lot of work to be done tomorrow."

"Yes, stationmaster, you've been busy all day, so get some rest."

Chu Lingyun responded, Wang Yuemin was actually tired for a long time, and this time he didn't insist on anything, and asked the driver to send him home.

As for those in the interrogation room, they are still locked up in the cell, but Chu Lingyun estimates that it won't be long before they will be released, after all, the real traitor Gao Yi has already been screened.
