Japanese spies are indeed cunning, and Chu Lingyun knows this very well. To deal with them, you must be extremely alert and not careless at all.
This adventure led the snake out of its hole, but the final result was failure.
It is not that Chu Lingyun has failed before. When arresting Yang Jian, it was once when Keiko Chishima and Huang Baichuan escaped, and another when Yoichi Yamada disappeared, but none of them were as serious as this time.
This time he successfully lured the person out, but made the other person commit suicide, so that there was no longer any hope of getting the other person's confession or information.
"Has Du Juan's home been searched?"
Wang Yuemin asked. Although Du Juan was dead, he had not had time to deal with many things, such as radio stations and code books. Wang Yuemin also thought of the issues that Chu Lingyun thought of before.
"I searched and found nothing." Chu Lingyun replied.
"What do you think?" Wang Yuemin asked again.
"Du Juan said there are two more intelligence agents. I plan to find a breakthrough in this aspect. The first is to find their dead mailbox. If you can find it, keep an eye on the dead mailbox and you may be able to find them. The second is their emergency contact.
In this way, I sent someone to the post office to take over the sorting team and asked them to take care of the letters. If an urgent contact letter appears, be sure to find out which mailbox it was posted from."
Chu Lingyun quickly said that there is actually a lot of uncertainty in his two methods.
The reason why many intelligence officers use dead mailboxes is because you don't know the location of the mailbox at all.
The dead mailbox is too random. It can be placed anywhere as long as it can put small things. It is also disguised outside. Even if you know the place where Xia Boyuan often goes, trying to find the location of the dead mailbox from there is tantamount to finding a needle in a haystack.
The second is the emergency contact information. Even if the other party has sent the letter and found out where it was posted, what if he deliberately walked far away to post it?
Besides, even if he mailed the letter nearby, there are so many residents around each mailbox, who would know who posted the letter.
Wang Yuemin knew this very well, but he did not refute Chu Lingyun.
"It's good to have a new direction. It doesn't matter even if you can't find anything. You have made enough contributions. This is a valuable experience for you in your growth."
Wang Yuemin did not have strict requirements for Chu Lingyun. Chu Lingyun was only a few months old when he was brought out, and it only took two months for him to take over the job.
Having achieved so much in such a short period of time, Wang Yuemin was extremely satisfied.
"Thank you, webmaster, for your teachings. I will try my best to check and won't let go of any hope."
Chu Lingyun nodded, and Wang Yuemin appreciated his attitude. The two chatted about other topics for a while, and Wang Yuemin asked Chu Lingyun to go back and rest.
Early the next morning, Chu Lingyun took Ni Loach to Xinyuan Tea House.
"Team leader, those in the French Concession knew that we were responsible for what happened at the Deming Hotel, but the station manager didn't admit it and pushed the people from the city government back."
Ni Loach was well-informed, and the patrol room in the French Concession was not full of wine and rice bags. With such a big movement, Chu Lingyun dispatched so many people and quickly found out their identities.
However, the French did not have any evidence, and Wang Yuemin refused to admit it. The French Concession Patrol Office was temporarily helpless.
"The time when Xia Boyuan arrives at the teahouse is not fixed?"
Chu Lingyun didn't reply, but asked instead that he didn't want to ask about the French Concession, and he couldn't ask. If the sky fell, there would be someone tall to hold it up, as long as it didn't affect his work.
"It's not regular, but I will definitely go there on weekends and occasionally during weekdays."
Ni Loach quickly replied that there might be a dead mailbox in the Xinyuan Teahouse. This was Chu Lingyun's guess. Or maybe it was just a cover. The dead mailbox was on his way to and from the teahouse.
In the absence of other clues, we can only take one step at a time and conduct a detailed investigation of all known clues.
Xin Yuan Tea House is located in the southwest of the city. It has a two-story facade. It is not big but very clean.
"Sir, what would you like to drink?"
As soon as Chu Lingyun led the people in, the shopkeeper came up to him, and Loach leaned into Chu Lingyun's ear and whispered: "Team leader, the shopkeeper is the boss, and his name is Zhang Hua."
Chu Lingyun smiled and clasped his fists and said: "Boss Zhang, excuse me, I have something to ask you. I don't know if it's convenient for you to speak alone."
"This boss is unfamiliar. I wonder what you want to ask me?"
Boss Zhang looked at Chu Lingyun carefully. Chu Lingyun was born in the military and had a masculine temperament. The few people around him were obviously not easy to mess with, except for Loach who looked slippery.
"You'll know in a minute."
Chu Lingyun glanced at the tables on the first floor. It was very early and there was only one person drinking morning tea.
"Go inside and talk."
Loach couldn't help but grab Zhang Hua. Just as Zhang Hua was about to struggle, he felt a hard object pressing against his back, and for a moment he didn't dare to move any further.
Chu Lingyun went directly upstairs and opened a private room, while Ni Loach pushed Zhang Hua in.
"You guys, I don't know what you want. If you want money, I can give it to you."
Zhang Hua clasped his fists repeatedly, with a look of fear on his face. At this moment, Ni Loach had already taken out his pistol and slapped it on the table.
"It doesn't cost you money, and it doesn't cost your life, but if our team leader asks you, you must answer honestly, otherwise you won't be able to leave this room."
Ni Loach scolded, and the shopkeeper nodded hurriedly and sat down across from 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 is 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 to drink tea, does he sit in a private room or drink in the hall downstairs?"
“It’s basically the lobby downstairs, and I only use private rooms when I’m with friends.”
"Friend, which friends did he come to have tea with? Are there many people here?" Chu Lingyun immediately asked.
"They are all teachers from their school. There are quite a few of them, basically five or six people. Teacher Xia is a cheerful person. He never refuses tea when others ask him to do so. However, these teachers do not ask him to do so often and only occasionally do so.
"
The shopkeeper's words made Chu Lingyun a little disappointed.
If five or six people come at one time, they will definitely not talk about anything secret. No matter how powerful the Japanese spies are, it is impossible to instigate all the teachers in the school to rebel at this time.
Even within the school, he doesn't develop anyone.
Because once someone he develops has a problem, he will be exposed directly, and the gain outweighs the loss.
In this case, there are so many of them just drinking tea and chatting, and Xia Boyuan is drinking tea in the hall. It is not easy to do something small. After all, there are many people there, and there is a danger of being discovered at any time.
At least now I don’t see the possibility of a dead mailbox in the teahouse.
"Loach, go to the toilet and see if there are any hidden compartments or anything like that?"
After thinking for a while, Chu Lingyun told Niyi again that the possibility of dead mailboxes in the lobby and private rooms was very small. There was only one place left in the teahouse that might have them, and that was the toilet.
