Wang Yuemin agreed with Chu Lingyun's point of view. The concession was like a country within a country. They really couldn't let go of their joints there. It was very risky to let Hanako Abe out at this time.
"That's a good idea, Ling Yun. I didn't expect you to act so steadily despite your age. It's very rare."
Wang Yuemin was even more satisfied with Chu Lingyun. He was neither arrogant nor impetuous. No wonder he could continuously trace the clues of Japanese spies and catch them.
"Webmaster, team leader."
Just as he was talking, Zhong Hui hurried back from outside. Huayuan Road was not too far away from them, and there was no one on the road at night, so Zhong Hui went back and forth very quickly.
Seeing Zhong Hui, Chu Lingyun hurriedly asked: "Have you found the place? What's the situation there?"
"I found it. The place is very remote. No. 109 is a private house. I have arranged for people to keep an eye on it."
"Be careful when you are staring at people so that no one notices you."
Wang Yuemin warned that the Japanese spies were cunning. When they originally targeted Yang Jian, they were discovered by the real Japanese spies and eventually allowed them to escape. Such a mistake must never happen again.
"Don't worry, webmaster, I have made arrangements and everything will be fine."
Zhong Hui hurriedly replied, while Chu Lingyun was frowning and lowering his head in thought.
Seeing that Chu Lingyun remained silent, Wang Yuemin couldn't help but ask: "Lingyun, what are you thinking about?"
"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 before? If so, how long will it take for it to arrive?"
What Chu Lingyun was thinking about just now was the statute of limitations.
Originally, he was thinking about how long it would take for Du Juan to see the letter after it was sent, but when he was thinking about this, he suddenly remembered that it also takes time to send a letter.
Not to mention now, even in later generations, the fastest express delivery in the same city will take a day, unless you find an errand. In this era, there is no need to think about it. Since it is an urgent contact and we will meet at noon the next day, how can Du Juan guarantee that it was sent the day before?
Letter, he can receive it the next day?
Wang Yuemin and Zhong Hui were stunned for a moment. Soon, they both understood why Chu Lingyun asked such a question.
Zhong Hui shook his head and said, "I don't know about letters sent to the same city, but the letters I send to my hometown usually take 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 seriously, what he received was a letter from the government department. Such a letter took three days. How could the letter sent by Du Juan be received in one day?
The email address for emergency contact is just a cover.
"Webmaster, since the letter could not be received in time and Du Juan used such emergency contact information, he must have a way to know the existence of this letter before it is sent."
Chu Lingyun spoke quickly, Wang Yuemin glanced at Zhong Hui, and they both said in unison: "Post Office."
"That's right, it's the post office. Du Juan must have placed someone there, otherwise she wouldn't have set up such emergency contact information."
Chu Lingyun said firmly, after receiving the letter and the day lily has cooled down, and if you can see it quickly after sending the letter, then there must be a spy arrangement in the post office.
Otherwise, I wouldn’t be able to see this letter, and it would be better not to have such emergency contact information.
"Ling Yun, thanks to your quick thinking, we were almost misled. If we really followed No. 109, the Japanese spies would laugh out loud."
Wang Yuemin said with a clear heart. In fact, the loophole in the time limit for sending letters is not difficult to discover. The most terrifying thing is that the authorities are obsessed with it. If Chu Lingyun hadn't reacted quickly, he would still have been kept in the dark.
"Stationmaster, now that we have discovered that Du Juan's real location is at the post office, No. 109 doesn't need to do anything to them. We don't even need to keep an eye on them, so as not to alert them."
Chu Lingyun said to Wang Yuemin, and Wang Yuemin nodded: "You are right, give up No. 109, and we will investigate the post office directly."
"Zhong Hui, ask your people to notify the guarding brothers to retreat. In addition, you can go to the prison and ask Abe Hanako whether her emergency contact information is to send a letter at a fixed location, or anywhere.
"
"Yes, I'll go right away."
Zhong Hui took the order and ran out, while Wang Yuemin stood up and kept walking back and forth.
He is well aware of the cunning of Japanese spies. There was Yang Jian in front of him, and now there is No. 109 Huayuan Road to confuse them. When dealing with these Japanese spies, you really have to be cautious.
Zhong Hui came back very quickly. He entered the office and said immediately: "Team leader, I asked, and Hanako Abe said any mailbox will do. I asked her specifically if it was only the mailbox or both the mailbox and the counter.
She said it can only be put in the mailbox."
"Well done, you can go and rest first."
After Chu Lingyun finished speaking, he looked at Wang Yuemin. Wang Yuemin continued to walk. Chu Lingyun understood his habits. Wang Yuemin liked this the most when thinking about problems.
"You can only send letters through the mailbox, not through the counter. This shows that Du Juan confirmed the existence of the letter through the mailbox. If any mailbox can be used, then he is not just a worker who collects letters from the mailbox on the street. This worker can detect the letter.
The person must be at the post office headquarters."
Wang Yuemin quickly analyzed the result. Chu Lingyun had thought of it before, but he still raised his thumb and said: "The webmaster is very clever. He thought of so much so quickly. I am still confused."
"Haha, you."
Wang Yuemin felt very comfortable with this flattery. He walked back and forth for a while and then said:
"We don't know the situation inside the post office, but there are only a few types of people who can access the letter, such as sorters or mailers. They don't use the counter mailing mode. They must be worried about delays on the counter, or on the counter.
They can't see the letters. In this case, we only need to investigate who has access to the letters in these mailboxes, and the scope of the investigation is suddenly reduced a lot."
"Webmaster, you are absolutely right. With your help, Webmaster, that Du Juan 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. We can only investigate tomorrow."
Wang Yuemin said regretfully, it was already past twelve o'clock in the evening, the time was indeed very late.
"Don't worry, stationmaster. I will definitely investigate all the suspects in the post office tomorrow."
Chu Lingyun stood up straight. Wang Yuemin admired his attitude very much.
"Ling Yun, you will be busy tomorrow. Go back and rest early and let your people rest too. There is still a lot of work to do tomorrow."
"Yes, webmaster, you have been busy all day, so please go to bed early."
Chu Lingyun responded. Wang Yuemin was actually tired for a long time. He didn't insist on anything this time and asked the driver to take him home.
As for those in the interrogation team, they are still in jail, but Chu Lingyun estimates that they will be released soon, after all, the real traitor Gao Yi has been identified.
