Chapter 68 Continued Investigation
Japanese spies are indeed cunning, and Chu Lingyun has a deep understanding of this. When dealing with them, one must be extremely alert and not be careless at all.
This adventure lured the snake out of its hole, but the end result was failure.
Chu Lingyun had failed before. When he was arresting Yang Jian, Chishima Keiko and Huang Baichuan escaped once, and Yamada Yoichi disappeared another time, but neither was as serious as this time.
This time he successfully lured the person out, but caused him to commit suicide, so there was no hope of getting his confession or information.
"Have you searched Dujuan's house?"
Wang Yuemin asked, although Du Juan was dead, there were many things he had not had time to deal with, such as the radio and the code book. The problem that Chu Lingyun had thought of before, Wang Yuemin also thought of at this moment.
"I searched, but found nothing." Chu Lingyun replied.
"What do you think?" Wang Yuemin asked again.
"Du Juan has two more intelligence agents under his command. I plan to look for a breakthrough from this aspect. The first is to search for their dead mailbox. If I can find it, I might be able to track them down by keeping an eye on it. The second is their emergency contact information. I've sent people to the post office to take over the sorting shift. I've asked them to keep an eye on the mail. If any emergency contact letter appears, make sure to find out which mailbox it was posted from."
Chu Lingyun quickly said that his two methods actually had great uncertainty.
The reason why many intelligence personnel use dead mailboxes is because you don’t know the location of the mailbox at all.
The dead mailbox is too random. Any place can be used as long as it can hold small items. There is also camouflage outside. Even if you know where Xia Boyuan often goes, trying to find the location of the dead mailbox from there is like looking for a needle in a haystack.
The second thing is the emergency contact method. Even if the other party sent the letter and we find out where it was posted, what if he deliberately walked far away to post it?
Besides, even if he posted the letter nearby, there are so many residents around each mailbox, how would he know who posted the letter?
Wang Yuemin was well aware of this, but did not refute Chu Lingyun.
"It's good to have a new direction. Even if you really can't find anything, it doesn't matter. You've made more than enough contributions. This is a valuable growth experience for you."
Wang Yuemin did not have any harsh requirements for Chu Lingyun. Chu Lingyun was so young. He had only been brought out by him for a few months, and he had only taken over the job for two months.
Wang Yuemin has long been extremely satisfied with the achievements made in such a short period of time.
"Thank you for your advice, webmaster. I will do my best to check and will not miss any hope."
Chu Lingyun nodded. Wang Yuemin appreciated his attitude very much. After they chatted about other topics for a while, Wang Yuemin asked Chu Lingyun to go back and rest.
The next morning, Chu Lingyun took Niu Qiu to Xinyuan Teahouse.
"Team Leader, the French Concession knows we were responsible for the attack on the De Ming Hotel. The stationmaster hasn't admitted it and has even pushed back against the city government."
Loach was well-informed, and the French Concession Police Station was not entirely composed of good-for-nothings. With such a big commotion and Chu Lingyun mobilizing so many people, he quickly found out their identities.
However, the French had no evidence, and Wang Yuemin refused to admit it, so the French Concession Police Station was temporarily helpless.
"Does Xia Boyuan have a fixed time to go to the teahouse?"
Chu Lingyun did not answer, but asked instead. He did not want to ask about the French Concession, nor could he ask. If the sky fell, there would be someone taller to hold it up. As long as it did not affect his work, it would be fine.
“It’s not fixed, but I definitely go on weekends and occasionally on weekdays.”
Loach quickly replied that there might be a dead mailbox in Xinyuan Teahouse. This was Chu Lingyun's guess, or maybe it was just a cover, and the dead mailbox was on the way he went to the teahouse.
In the absence of any other clues, we can only take one step at a time and conduct a detailed investigation of all known clues.
Xinyuan Teahouse is located in the southwest of the city. It has two floors and is not big but very clean.
"Sir, what would you like to drink?"
As Chu Lingyun led his men in, the shopkeeper came forward to greet them. Loach leaned close to Chu Lingyun's ear and whispered, "Team leader, the shopkeeper is the boss, his name is Zhang Hua."
Chu Lingyun smiled and cupped his fists, saying, "Boss Zhang, sorry to bother you. I have something I want to ask you. I wonder if it's convenient for you to talk privately."
"This boss looks unfamiliar. What do you want to ask me?"
Boss Zhang looked at Chu Lingyun carefully. Chu Lingyun came from a military background and had a masculine aura. The people around him, except for Loach who looked slippery, were obviously not easy to mess with.
"You'll know in a moment."
Chu Lingyun glanced at the tables on the first floor. It was very early and there was only one person having morning tea.
"Let's talk inside."
Loach grabbed Zhang Hua without saying a word. Just as Zhang Hua was about to struggle, he felt a hard object pressing against his back and he dared not move anymore.
Chu Lingyun went upstairs directly and booked a private room, and Niu Qiu pushed Zhang Hua in.
"My dear friends, I don't know what you want. If you want money, I can give it to you."
Zhang Hua clasped his fists repeatedly, his face full of fear. Loach had already taken out a pistol and slammed it on the table.
"We don't want money, and we don't want your life, but you must answer our leader's questions honestly, otherwise you can't leave this room."
Loach scolded, and the shopkeeper nodded hurriedly and sat down opposite Chu Lingyun tremblingly.
"Boss Zhang, do you know this person?" Chu Lingyun took out Xia Boyuan's photo and pushed it in front of Zhang Hua.
"I know him. He's Teacher Xia from a nearby middle school. He often comes to my place for tea." The shopkeeper nodded hurriedly.
Chu Lingyun asked, "When he comes for tea, does he sit in a private room or in the lobby downstairs?"
“I usually use the lobby downstairs, and only occasionally use the private rooms when I’m with friends.”
"Friends, which friends did he come to drink tea with? Were there many people coming?" Chu Lingyun asked immediately.
"They are all teachers from their school. There are quite a few of them, usually five or six. Teacher Xia is a straightforward person. He never refuses when someone asks him to treat him to tea. However, these teachers don't ask him to treat them often, only occasionally."
The shopkeeper's words made Chu Lingyun a little disappointed.
Five or six people coming at a time definitely wouldn't talk about anything secret. No matter how powerful the Japanese spies were, it was impossible for them to turn all the teachers in the school against their will at this time.
Even within the school, he doesn't develop any relationships.
Because if there is a problem with the person he develops, he will be directly exposed, which will not be worth the loss.
In this case, so many of them were just drinking tea and chatting, and it was not easy for Xia Boyuan to do anything while drinking tea in the hall. After all, there were many people there and he was in danger of being discovered at any time.
At least for now, there is no possibility of a dead mailbox in the teahouse.
"Loach, go to the bathroom and see if there's a secret compartment or something like that?"
After thinking for a while, Chu Lingyun instructed Niu Qiu again that it was very unlikely that there were dead mailboxes in the lobby and private rooms. There was only one place in the teahouse where it might be, and that was the toilet.
