The person in charge of collecting donations at the alley stopped Song Shutang in his path and gave him a commemorative scroll.
"Sir, this is our donation commemorative volume. If you need to write family letters, couplets, marriage letters, petitions, etc. in the future, you can rely on this volume. We will provide help free of charge." The person in charge is a girl in her twenties, wearing a beige top and leaving a
He has short hair that touches his ears and speaks fluently.
"Leave it to those who need it." Song Shutang does not need such service.
"Let's keep this as a souvenir." The girl still insisted on handing over the souvenir roll.
There are some slogans written on a piece of paper, which also proves the donation.
This item also encourages everyone to donate.
Not everyone can obtain it. Nowadays, paper is expensive and is in short supply. It will only be awarded if the donation amount reaches a certain level.
"Okay." Song Shutang did not refuse.
"May I ask your name, sir?"
"Song Shutang."
The girl quickly wrote her name and the donation amount on the commemorative roll, and then stamped it to complete it.
"Please put it away."
"Thanks."
"We should thank you for your generosity and patriotism."
I took the commemorative scroll and glanced at the location where it was stamped "Shancheng Women's National Salvation Federation".
After thanking her again, the girl continued busy with her work. Song Shutang put the commemorative scroll into his pocket and entered the restaurant with Long Hao for dinner.
After finishing their meal at the hotel, the donation drive was still going on. Instead of joining in, the two called a rickshaw waiting at the intersection to go to the Secret Service.
The location of the Secret Service Corps is at the Wanglongmen Lianghu Guild Hall on Linsen Road.
Song Shutang had never been here before, but he and Long Hao had previously gone to Central Park to participate in a charity sale. Central Park was not far from Wanglongmen.
Take a rickshaw all the way to the Lianghu Guild Hall.
The Lianghu Guild Hall is located on a slope with a height difference of nearly 40 meters. The architectural layout is adapted to local conditions, with layered platforms falling layer by layer. It is fully integrated with the natural terrain and has strong mountain characteristics.
Most of the buildings follow the layout of the courtyard houses in the Ming and Qing Dynasties, adopting different roof structures, such as hanging mountains, rolling sheds, resting mountains and other forms.
As previously introduced, there are three armed brigades under the Secret Service Corps, a plainclothes squadron, an action group and a detention center.
Most people within the bureau call this detention center an "elementary school."
Because it is a place used to temporarily imprison revolutionaries and military agents.
Boss Dai counts the imprisoned agents as "cultivators".
There are "primary schools" and "middle schools" and "universities".
The Baigongguan Detention Center located in the north of Xiaogeleshan in Ciqikou, Shancheng City, is the "middle school". The Xifeng Prison located in Yanglangba, Xifeng County, Guizhou is the "university".
People who graduate from "elementary school" are basically sent to "middle school" or "university" for long-term training, so no insiders want to know more about the detention center in Lianghu Guild Hall.
When Song Shutang first came back to the mountain city, if he couldn't survive the interrogation department safely, he might eventually be sent to an "elementary school" and then to a "middle school" or "university" to be a long-term "cultivator."
Fortunately, we are not here at the detention center today.
The two of them announced their intentions at the reception area at the door. After making a call, they soon saw Jiao Teng appear.
"Long time no see, Team Leader Song." Jiao Teng also knew that Song Shutang had appointed the deputy team leader.
"Captain Jiao is here and safe."
"Come in quickly." Jiao Teng nodded to Long Hao as a greeting.
Following Jiao Teng into the Lianghu Guild Hall, he walked all the way up the stairs to his office. After asking the two of them to sit down, he arranged for someone to pour them two cups of tea.
"Team Leader Song drinks tea."
"Captain Jiao is welcome."
When Jiao Teng saw Song Shutang again this time, he actually felt a little bit confused in his heart. It was clear that not long had passed since the last time they met, but many things had changed.
Song Shutang became the deputy team leader.
The first time we met, we still had to look at Long Hao's face, but this time he was no longer what he used to be.
And today Zhu Yue called to tell him that Song Shutang was coming in the afternoon, and also told him about his military rank. Jiao Teng could only say that he was young and promising.
Even if Long Hao doesn't follow him this time, he won't be in trouble when facing Song Shutang Jiao Teng.
Not to mention that you asked others to help you, but just because of your ability, it would be inconvenient for you to turn against others.
After a few words of greeting, Song Shutang took the initiative to ask: "I wonder what Captain Jiao needs me to do here?"
Jiao Teng also became serious when it came to serious matters.
"This matter is a long story, and it starts from October last year."
"In late October last year, the team got a clue and identified a teahouse as a meeting place for two intelligence agents. However, the meeting time, people, passwords and other information were completely unknown. In the end, the team discussed that the investigation method would be to take photos and collect photos of those who came and went in the teahouse.
People are filming for a long time in order to find suspicious people."
After listening to Jiao Teng's words, Long Hao couldn't help but say: "There are countless people coming and going in this teahouse every day. It is impossible to take pictures of everything, and there are so many repeat customers. Even if you use photos to find the same person who has entered the teahouse multiple times, I'm afraid
The majority of people meet this condition.”
This method is not very good in Long Hao's opinion.
Jiao Teng explained: "Intelligence agents will not come and go to the teahouse every day. There are time intervals and regularity in the contacts. Regular tea drinkers can be easily excluded. By taking long-term recordings and comparing them, we can find out who came to the teahouse at a specific time.
And if the two people meet at the same specific time, then the probability that they are contacts is extremely high."
Song Shutang understood what the Special Agent Corps was thinking.
The meeting point is at the teahouse.
The number of contacts is determined by two persons.
Then the next thing to do is to find the time intervals between two strangers who appear with the same frequency.
For example, A appears in a teahouse on the 10th, and also appears on the 25th.
Then B and A have the same time, and A and B have the highest probability of being the contact person.
However, there are many teahouses in the mountain city, and more people come and go from the teahouses every day. You will definitely not be able to remember it by relying on your eyes.
And the time period may be very long, so photos must be taken with a camera as records for easy retrieval.
"How long did this work last?" Song Shutang asked.
"It lasts until the end of December."
"More than two months?" This workload is probably very large.
"Yes."
"Anything found?"
"No." Jiao Teng smiled bitterly.
"Is there a long time between connections?" Song Shutang asked.
Is it possible that we only see each other once in more than two months?
It is not that such arrangements do not exist.
But Jiao Teng shook his head and said: "According to the information we have, the time interval between connections will not exceed one month."
"That is to say, during the period when the Secret Service Corps was responsible for the filming and investigation, the other party contacted the other party at least twice, which is enough to support the use of photos as a basis to identify the contact person." Song Shutang believes that time is enough.
"This is true in theory, but in practice, no clues can be found from the photos."
"There was a problem during the filming?"
"As I just said, the teahouse is very crowded with people every day, and sometimes the photo is missed. After all, there are sometimes many people coming in and out at the same time, and it is difficult to take pictures of them all."
"Then why not extend the shooting time and only last until the end of December?" Song Shutang feels that since you have decided to investigate like this, you should insist on continuing to shoot and get more clues before you find any clues.
"A bombing by the Japanese army at the end of December destroyed the teahouse. Since then, the teahouse has been closed and has not yet been repaired. As the contact person, I will definitely learn this news and will definitely change the meeting place, so our investigation cannot continue.
Go down."
It wasn't that Jiao Teng and the others didn't want to continue the investigation at that time, but the conditions no longer allowed it.
The Japanese bombing just happened to blow up the teahouse, which prompted the contact person to change the contact location. The investigation method could no longer be used, so the secret service team had to interrupt the investigation. Instead, they began to carefully look at the photos taken, hoping to find clues from them, but found nothing. In the end, they could only
