In fact, Li Yixin was a little resistant to using the emergency backup contact method with the 'bodyguards'.
In stealth work, the less people know about the cover identity and real identity of the sleeper, the better.
Because the more people who know, the greater the chance that the true identity of the sleeper will be exposed, and any intelligence organization will keep the true identity of the sleeper agent secret, and the fewer people in the know, the better.
This is the fundamental reason why every agent has a code name, and even these code names are classified as secrets.
For example, Li Yixin's code name within the Central System is 'Young Master', Deputy Director Ye pays great attention to the secrecy of his identity, and there is no one else who knows Li Yixin's identity except Deputy Director Ye.
In the official intelligence documents within the Central Union, for the information provided by Li Yixin, in the description of the intelligence source, he will only have a modern number at most, and his name and identity are completely absent.
Even the 'bodyguards' and the manager of the Central Unification Headquarters, who announced to Li Yixin before Li Yixin's departure, that he would be dispatched to the occupied area, also did not know what Li Yixin's identity was in Stone Town now.
The 'bodyguard' only knows that Li Yixin's code name is 'Young Master' so far, and he doesn't know anything about the rest of the situation, and the manager doesn't even know Li Yixin's code name.
Even Deputy Director Ye's henchman He Guangzong was assigned to wait in Stone Town to carry out smuggling operations, but he also didn't know Li Yixin's code name and cover identity.
Similarly, Li Yixin's identity on the side of the party organization has also been kept very strictly secret, and only the deputy minister and traffic officer Lao Wu know Li Yixin's true identity.
Even Yin Qunli, an intelligence officer in Li Yixin's group, only knew Li Yixin's cover identity in Stone Town because the Military Commander's Stone Town Station was cracked by the Special High School.
As a sleeper officer, the secrecy of identity is a matter of life, so generally speaking, in order to protect the intelligence agents who penetrate the enemy, various intelligence organizations use a one-line contact to command.
In this regard, the party organization is more important than the central unification, because the party organization has always been in a state of underground activities, so basically the method of one-line contact with the latent intelligence agents has been adopted to avoid the exposure of the hidden intelligence agents as much as possible.
As far as Li Yixin knows, the alternate emergency contact method with the 'bodyguard' must meet directly with the 'bodyguard', so Li Yixin's heart is a little resistant to this contact method.
However, in order to keep in touch with the headquarters of the Central Union, Li Yixin had to use this backup emergency contact method to restore contact with the headquarters of the Central Union after the safe contact method of the dead mailbox was deactivated.
He went to the bookstore to buy a copy of the "New Dictionary of Correcting Zhuyin Chinese" and a copy of today's declaration, went to Hushan Park, and sat on a somewhat remote wooden bench in the northeast corner of Hushan Park according to the joint regulations.
Today is September 23rd, and every day when the mantissa of the date is 3, or a multiple of 3, the 'bodyguards' will come to Hushan Park to wait to connect with the 'young master', which is the time limit for this alternate emergency contact method.
After Li Yixin sat down, he put the "New Dictionary for Correcting Zhuyin" at his left foot, and opened the dictionary and threw it on the ground, pretending that the dictionary had accidentally fallen from the bench.
At the same time, he also needs to pretend to read today's declaration and wait for the 'bodyguards' to come and connect.
In order to give two strangers a reasonable reason to contact, the designer of this contact method will ask the 'bodyguard' to come forward to remind Li Yixin that the dictionary has fallen to the ground, and say the joint code word during the conversation, while Li Yixin confirms the identity of the other party.
Li Yixin waited on this bench for more than an hour, this place is relatively remote, and tourists rarely come here, so Li Yixin has been observing the occasional tourists who appear here during this time, but no one has come forward to talk to him.
At this time, the sun was about to set, and just when Li Yixin felt that the park was about to close, a park cleaner came next to him.
"Sand ......
Sand ......"
The janitor looked like he was cleaning the park when it was about to close, slowly sweeping away the leaves that had fallen on the ground with a large broom.
After a while, the cleaner swept to the bench where Li Yixin was sitting, he saw the dictionary on the ground, and asked, "Sir, is this your book?"
You see it's all falling to the ground. ” Li Yixin looked at the cleaner carefully and said in a grateful tone: "Ah, it's my book."
I read the newspaper so focused on you that I didn't pay attention to the book dropping, thank you for the reminder. ” Immediately afterwards, Li Yixin stared at the other party and asked, "I've finished reading this newspaper, where is the garbage bin here, I'll throw away the newspaper." ” Up to this point, the conversation between the two sides has been a normal conversation in the eyes of passers-by or tourists.
But the others didn't notice at all that Li Yixin had already spoken the code words at this time.
Because for many people, things like newspapers can be used for waste even after reading, they can be used to glue windows, or they can be used as ignitions when lighting fires and cooking, they can also be used as book covers to protect books, and even used to wrap food.
Therefore, Li Yixin said that he would throw away the newspaper unless he was rich, and ordinary people would not waste it like this, and this sentence happened to be a code word.
This is also to prevent someone from inadvertently doing all the previous actions correctly and causing misidentification of the connector.
Without hesitation, the cleaner replied, "Sir, there is a garbage bin on the right-hand side outside the south gate of the park. ” With that, the cleaner buried his head again and began to continue his cleaning work, as if none of this had anything to do with him.
The code is right!
Li Yixin looked around and found that no one was passing by now, so he asked in a low voice: "Bodyguard?"
” The cleaner asked softly without raising his head, "Young Master?
” "It's me, after you received the alarm from me, did He Guangzong come to you?"
"No, he can't find me anymore.
As soon as I saw the alarm signal you drew on the dead letter, I immediately took emergency measures to evacuate and changed my accommodation with the radio.
He Guangzong once went to my original residence once to send a telegram to the headquarters.
So I felt that I had to be prepared, so I evacuated my old residence. ” "Good, you did it very correctly and you were alert.
What is your current cover identity?
How do we keep in touch in the future?
Li Yixin asked softly, observing the situation while asking.
The janitor said: "My current cover identity is a rickshaw driver, registered with the police station, and there is no doubt about the cover identity. ”
