Chapter 58 Another Cover
Wang Yuemin agreed with Chu Lingyun's point of view. The concession was like a country within a country. Making contact there really made it difficult for them to move freely. It would be very risky to let Abe Hanako go at this time.
"That's a good idea, Lingyun. I didn't expect you to be so steady despite your young age. It's quite rare."
Wang Yuemin was even more satisfied with Chu Lingyun. He was neither arrogant nor impatient. No wonder he was able to track down clues about Japanese spies and catch them continuously.
"Stationmaster, team leader."
As he was speaking, Zhong Hui hurried back from outside. Huayuan Road was not too far from them, and there was no one on the road at night, so Zhong Hui made a very fast trip back and forth.
Seeing Zhong Hui, Chu Lingyun hurriedly asked: "Have you found the place? What's the situation there?"
"Found it. It's in a remote area. No. 109 is a private house. I've already arranged for someone to keep an eye on it."
"Be careful when you're marking someone, don't let anyone notice."
Wang Yuemin warned that the Japanese spies were cunning and that when they were targeting Yang Jian, they were discovered by real Japanese spies and eventually allowed to escape. Such a mistake must never happen again.
"Don't worry, Station Master. I've made all the arrangements. Nothing will happen."
Zhong Hui replied hurriedly. Chu Lingyun was frowning and thinking with his head down.
Wang Yuemin saw that Chu Lingyun had been silent, and couldn't help asking: "Lingyun, what are you thinking about?"
"No, we seem to have overlooked a problem."
Chu Lingyun looked up and asked the two of them, "Stationmaster, Zhong Hui, do you usually send letters? If so, how long does it take for a letter to arrive?"
What Chu Lingyun was thinking about just now was the time limit.
Originally, he was thinking about how long it would take Dujuan to see the letter after it was sent, but when thinking about this, he suddenly remembered that sending a letter also takes time.
Not to mention now, even in the future, the fastest express delivery in the city would take a day, unless you hired a runner. In this era, it was even more impossible. Since it was an urgent communication, and they had to meet at noon the next day, how could Du Juan guarantee that he would receive the letter he sent the day before?
Wang Yuemin and Zhong Hui were both stunned for a moment, but soon they both understood why Chu Lingyun asked this.
Zhong Hui shook his head and said, "I don't know about letters sent to people in the same city, but letters I send to my hometown usually take more than ten days to arrive."
"I received a letter from someone in the same city, and it took three days to arrive."
Wang Yuemin sat up straight and said seriously that the letter he received was from a government department, and it took three days to receive such a letter. How could the letter sent by Du Juan be received in one day?
The emergency contact address is just a cover.
"Stationmaster, since the letter couldn't be received in time, and Du Juan used this emergency contact method, he must have found out about the existence of this letter before it was sent."
Chu Lingyun spoke quickly. Wang Yuemin glanced at Zhong Hui, and they both said in unison, "Post Office."
"Yes, it's the post office. Du Juan must have someone planted there, otherwise he wouldn't have set up such an emergency contact method."
Chu Lingyun said with certainty that by the time the letter was received, the food would be cold, and the letter could be seen quickly after it was sent, so there must be Japanese spies arranged in the post office.
Otherwise, if I can't see this letter, it would be better not to have such emergency contact information.
"Lingyun, thank goodness you're smart. We were almost misled. If we had really targeted No. 109, the Japanese spies would have laughed their heads off."
Wang Yuemin said with lingering fear that in fact, the loophole in the time limit for sending letters was not difficult to discover. The most terrifying thing was that those involved were confused. If Chu Lingyun had not reacted quickly and thought of this, he would still be kept in the dark.
"Stationmaster, since we've discovered Dujuan's true 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, lest we alert them."
Chu Lingyun said to Wang Yuemin, and Wang Yuemin nodded: "You are right, give up No. 109 and investigate the post office directly."
"Zhong Hui, have your men notify the brothers on guard to retreat. Also, go to the prison and ask Abe Hanako if her emergency contact information requires a letter from 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 was well aware of the cunning of Japanese spies. In front, there was Yang Jian, and now there is No. 109 Huayuan Road to confuse them. When dealing with these Japanese spies, he really had to be cautious.
Zhong Hui returned quickly and immediately said as he entered the office, "Team Leader, I asked, and Abe Hanako said any mailbox would do. I specifically asked her if it was only the mailbox or both the mailbox and the counter, and she said it could only be placed in the mailbox."
"Good job, go and rest first."
After Chu Lingyun finished speaking, he looked at Wang Yuemin. Wang Yuemin continued walking. Chu Lingyun understood his habit. Wang Yuemin liked to do this the most when thinking about problems.
"The letter can only be sent through a mailbox, not a post office counter. This means Du Juan confirmed the existence of the letter through the mailbox. If any mailbox can be used, then it's not just a worker on the street collecting mailbox letters. The person who discovered the letter must be at the post office headquarters."
Wang Yuemin quickly analyzed the results he came up with. Chu Lingyun had already thought of them before, but he still gave a thumbs up and said, "Webmaster, you are very smart. You have thought of so many things so quickly. I am still confused."
"Haha, you."
Wang Yuemin was very pleased with the 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 could have accessed this letter, such as sorters or mail clerks. They don't send letters over the counter, so they must be worried about delays at the counter, or they might not be able to see the letters there. In this case, we only need to investigate who had access to the letters in these mailboxes, which greatly narrows the scope of the investigation."
"Stationmaster, you are absolutely right. With your help, we will definitely catch Dujuan this time."
Chu Lingyun said this with a smile, and Wang Yuemin was in a good mood, and his sleepiness disappeared a lot.
"Unfortunately, it's too late now. I can only investigate tomorrow."
Wang Yuemin said with regret that it was already past midnight and it was indeed very late.
"Stationmaster, rest assured. Tomorrow I will thoroughly investigate all suspects in the post office."
Chu Lingyun stood up straight, and Wang Yuemin admired his attitude very much.
"Lingyun, you still have a lot of work to do tomorrow. Go back and rest early, and let your people rest as well. There is still a lot of work to do tomorrow."
"Yes, Station Master, you've been busy all day, so go to bed early."
Chu Lingyun responded. Wang Yuemin was actually already tired, so he didn't insist this time and asked the driver to take him home.
As for those in the interrogation team, they are still imprisoned in the cells, but Chu Lingyun estimates that they will be released soon. After all, the real traitor Gao Yi has been identified.
