Lao Li Tou's confession is nothing to see, Li Zheng cared about him before, he was very good to him, Lao Li Tou has no relatives and friends, he has never been cared for like this, and it is easy to make Li Zheng a confidant.

Li Zheng explained what happened to him, and he firmly remembered it.

And Li Zheng is really helping the Japanese, but he doesn't know that the other party is Japanese, he doesn't even know what the other party looks like, according to his confession, a man who covers himself very tightly found him three years ago and asked him if he was willing to make money.

At that time, their family was not having a good time, and they were naturally willing to make money.

Then the man instructed him to find a way to read all the letters every day, and gave him three addresses, and once the letters from these three addresses appeared, he would immediately go to the same house number in Taiping Lane to draw a secret mark.

This secret mark is very simple, it is a cherry blossom.

Li Zheng didn't know that it was a cherry blossom, but Chu Lingyun understood that such a secret mark was to ensure that no children were scribbling on the wall and causing misleading.

The three addresses are No. 109 Huayuan Road, No. 68 Changjiang Road and No. 77 Jiang'an Street.

As long as Li Zheng strictly does this, the other party will give him fifteen yuan a month, which was Dayang before, and now it is fiat currency.

And every time he reacts in time, he will give him an extra fifty yuan, in order to make this money, Li Zheng deliberately befriended Lao Li Tou, gave Lao Li Tou some small favors, and successfully bought him.

In the past three years, only the letters at No. 68 Changjiang Road and No. 109 Huayuan Road have appeared, and he has never seen the letter on Jiang'an Street.

In fact, Li Zheng really wanted to see these letters appear, and once they appeared, it meant that he could earn an extra fifty yuan.

With his family situation, fifty dollars is very important to him.

This is also the reason why Li Zheng's income is not enough, but he is not short of money, and the Japanese give him a monthly subsidy of 15 yuan, so that his life is enough security.

The letter on Changjiang Road appeared a year ago, and it was too long since the matter passed, and there was no way to check it, as for the letter on Huayuan Road, it was a blank letter they sent this time in order to lure out the cuckoo.

The plan was very successful, and Cuckoo did come out, but unfortunately Abe Hanako had an accident, which made Cuckoo aware of it, and in the end both of them died.

Chu Lingyun didn't know what mistake Abe Huazi had made, which aroused Du Juan's suspicion.

But he believed that Abe Hanako did not send a message to Cuckoo, otherwise Cuckoo would not have shot Abe Hanako, but would have taken her to flee with her.

They didn't even have to escape from the French Concession, as long as they escaped to the patrol room, Chu Lingyun would have no way to attack them again.

"Hanwen, you send two people to the post office, enter the sorting class to take over the work of sorting letters, and find letters at No. 77 Jiang'an Street and No. 68 Changjiang Road, report immediately."

Chu Lingyun instructed Shen Hanwen that the loach was still out to inquire about the news and did not come back, while Zhong Hui was searching the cuckoo's lair, and only Shen Hanwen was by his side among the three team leaders.

"Yes."

Shen Hanwen took the order and ran out to take over the sorting class, which was Chu Lingyun's temporary idea.

Through Li Zheng's confession, it can be judged that there are three intelligence officers under Du Juan, and now that Abe Hanako is dead, there are still two left.

They are usually contacted through a dead mailbox and do not see each other except in an emergency.

Now that the cuckoo is dead, there will definitely be no one to pick up the other two agents' dead mailboxes, and if no one picks them up for a long time, the agents may have doubts and may use the emergency contact information to apply for a meeting.

But it's only possible.

And even if the other party sent such a letter, when and where they met, Chu Lingyun didn't know anything.

Abe Hanako is at the Deming Hotel, and the other two intelligence agents may not be there, and the time may not be the same.

It can be said that the possibility of achieving results in this way is extremely low, but no matter how low it is, it is also a direction, and Chu Lingyun will not miss any clues now.

It wasn't until the evening that the loaches returned to the station.

"Team leader, I have found out, Xia Boyuan's usual life is very regular, he has a good reputation in school, he is dedicated to his students, he takes care of his colleagues, he is a teacher, his income is not low, and there is only one person who lives, usually other teachers have difficulties to talk to him, he never refuses."

"Xia Boyuan doesn't have any hobbies, except for going to work, he drinks tea, he often goes to Xinyuan Tea House to drink tea, and then he occasionally goes to the park, does not go to brothels and casinos, and has no other bad habits."

The results of the loach investigation are very detailed, and Xia Boyuan, as the leader of the cuckoo team, must go to the location of these dead mailboxes if he wants to receive information from his intelligence officers.

The places he frequented were most likely the addresses of the dead mailboxes.

There is Abe Huazi's death mailbox in the park, Xinyuan Teahouse is another place, and where is the third place, Chu Lingyun didn't expect it for the time being.

"Have you checked the people from Xinyuan Teahouse?" Chu Lingyun thought for a moment, and then asked.

"Checked, the owner of Xinyuan Tea House is a local, has a family, is usually normal, and there is nothing abnormal with a few guys."

The loach nodded immediately, the loach is very good, let him do an investigation, as long as he thinks it may be useful, whether it can be used or not, he will check it first.

"It's too late today, let's go to Xinyuan Tea House tomorrow."

Chu Lingyun looked at the time, since yesterday he has been busy until now, many people have not closed their eyes, and the iron-beaten man can't stay up all the time, so everyone must be given enough time to rest.

Others can rest, but he can't, Wang Yuemin hasn't left, obviously waiting for his report.

After sorting out the information, Chu Lingyun hurriedly came to Wang Yuemin's office and knocked lightly on the door.

"Come in."

Wang Yuemin's voice came from inside, Chu Lingyun opened the door and walked in quickly.

"Stationmaster, this time it was my mistake that made Cuckoo discover the abnormality, killed Abe Huako on the spot, and committed suicide himself, Lingyun is incompetent, please punish him."

Chu Lingyun stood in front of Wang Yuemin's desk and admitted his mistake when he came up.

This time he did make a mistake, and no one was to blame.

"Come, sit down."

Wang Yuemin didn't blame, pulled Chu Lingyun to the sofa on the side and sat down, then sighed, and said slowly: "Who is not a sage and sage, I have not made mistakes?" It's not terrible to make mistakes, it's important to correct them and avoid making the same mistakes in the future. ”

"Yes, stationmaster."

Chu Lingyun sorted out his thoughts, and after the letter was delivered, a series of actions were reported to Wang Yuemin in detail.

Everything went smoothly before, and even the joint between Abe Hanako and Azalea didn't have anything at first, and then I don't know why Abe Huako suddenly checked Abe and was exposed.

After listening to what Chu Lingyun said, Wang Yuemin nodded and said: "You have done a good job, this time it is Abe Huazi's fault, she failed to hide herself well, so that the cunning Japanese spy can see the flaw." ”
