The two of them were-for-tat at the door of the secret service department, perhaps it is more accurate to say that Yao Bing was-for-tat, because Yu Jingque had a calm and breezy feeling from beginning to end.

"Is Captain Yao out busy?" Yu Jingque asked with concern.

"Busy for Corey, not as good as Captain Yu, not idle." Yao Bing ridiculed Yu Jingque, saying that he had no task and should not be taken seriously.

"It's going to get busy." Yu Jingque said casually, as if telling Yao Bing that Wan Qun would start to trust me.

Yao Bing saw that there was no one around, stepped forward, and said to Yu Jingque: "Come back when you come back, but don't talk nonsense, otherwise you will ......"

Captain Yao laughed.

"Besides, what else can I do?" Yu Jingque's words are a bit provocative.

What can you do?

The Security Bureau treated me like this, I'm not still good, can you be more ruthless than the Security Bureau?

In the face of Yu Jingque's fearless appearance, Yao Bing's cruel words seemed to have no effect at all.

Wan Qun's car came over, Yao Bing glanced at Yu Jingque, went down the steps, greeted Wan Qun, and went out to get busy.

Wan Qun got out of the car and saw Yu Jingque still standing here, and he saw the scene of the two standing together and talking just now, he saw it in the car.

"10,000 shares." Yu Jingque came down the steps and greeted Wan Qun.

"Got a quarrel?" Wan Qun asked.

"No, we chatted a couple of words." Yu Jingque denied it.

While walking inside, Wan Qun said to Yu Jingque, who was following him: "The secret service department is something that needs to work, you understand. ”

"Don't worry, Chief of Unit, I will work hard and won't cause chaos to the Secret Service Section." The beating of the ten thousand groups, Yu Jingque naturally understood.

"That's good." Wan Qun didn't say anything.

When passing by his office, Yu Jingque was about to go in, but Wan Qun said: "Go to the communication class and call Team Leader He, come to my office." ”

"Yes." Seeing Wan Qun go away, Yu Jingque turned his head and went to the communication class, knocked on the door and called He Siliang.

"Squad Leader He, the 10,000-stock captain has already arrived, calling you to the office." Yu Jingque stood at the door and said, not going in.

Communication class, ordinary people can't go in, Yu Jingque doesn't want to make trouble for himself, if he can stand at the door and say, there is no need to go in.

He Siliang was not wearing a police uniform, but in a suit, raised his head from the table, helped his gold-wire glasses, held a document in his hand, and walked out.

Sending He Siliang to Wan Qun's office, Yu Jingque thought that his task was completed, who knew that Wan Qun said: "You also stay." ”

"Yes." Yu Jingque said yes, turned around and closed the door of the office, but he was a little happy in his heart, he knew that Wan Qun began to use himself.

Although Cai Wangjin said that he let himself rest and rest, his injury was not a broken muscle, and there were Li Qingxi and others below, so he couldn't be idle all the time.

"Sit down." Wan Qun said.

This sentence was said to Yu Jingque, He Siliang had already sat down, and there was no need for Wan Qun to speak.

He pulled a stool over and sat side by side with He Siliang.

He Siliang did not immediately talk to Wan Qun, but turned his head to look at Yu Jingque, and looked at Yu Jingque through the lenses of his glasses.

"How does it feel to be closed by the ghost door?" He Siliang asked.

"Reincarnate as a human being." Yu Jingque said.

"Since they are all reincarnated, they have never thought about being a good person?" He Siliang's question was very interesting, which made Yu Jingque confused about his intentions.

Yu Jingque glanced at Wan Qun, and when he saw that Wan Qun didn't speak, he opened his mouth and said: "I'm a police officer, punishing adultery and eliminating evil, isn't it a good person?" ”

"If you give it to me, don't be official." What He Siliang said was a bit ambiguous, and when someone heard it, he might have to go to Cai Wangjin to complain.

But he dared to say it in front of Wan Qun, and it seemed that he was not worried.

There are some things that He Siliang's identity can say, but Yu Jingque can't, he wisely chooses to shut up.

"It's boring." He Siliang saw that there was nothing fun to do, and shook his head.

"Alright, let's get down to business." Wan Qun saw that it was almost there, and spoke.

Talking about the matter, He Siliang put the document in his hand on the table, reversed it and showed it to Wan Qun.

"This is this time, intercepted messages, what did you find?" He Siliang asked Wan Qun.

Wan Qun looked up in embarrassment and said, "Deliberately? ”

"No, I mean to say that the message changes a lot, and the way it is encrypted is different every time." He Siliang knocked on the document and made his own records, but Yu Jingque and Wan Qun really couldn't understand it.

Yu Jingque was on the side, frowning and said, "You mean, the enemy is no longer using a single codebook, but will change the password at any time?" ”

"Yes." He Siliang nodded.

"Where did they get their codebooks?" Wan Qun asked.

He Siliang said unceremoniously: "The focus of this matter is not in the code book, but in the rapidly changing password." ”

"Isn't it a codebook yet?" Wan Qun thinks that He Siliang did not deliberately dismantle the stage.

Seeing that he couldn't understand, He Siliang put the documents together and said: "Frequent password changes are very common in foreign countries, which effectively ensures the security of messages, so that we have no way to decipher the code by accumulating messages. ”

It seemed that he understood or not, anyway, Yu Jingque and Wan Qun nodded along with it, as if they understood.

"There are many sources of this password, and they can put the code book on the people who come and go to the ice city, and these people may not know that they are in their luggage, or they have these things on their bodies." He Siliang's words, Yu Jingque and Wan Qun can understand.

They did catch such people.

But these people are completely unaware of what is going on, they become the bridge to transport the password, if the password is obtained by the person who receives it in Ice City, they will use the password, if not, they will not use it.

Therefore, the people of the secret service department, it is useless to get these passwords.

"Now let's put down the source of the password and focus on the person who sent the report." He Siliang changed the subject.

"The person who sent the report?" Wan Qun muttered.

He Siliang opened the cap of the pen and wrote two words on the paper with the pen: "Time." ”

"When?" Yu Jingque didn't understand.

"There is a strict time limit for the enemy's reports, and they probably know how long it will take us to determine their location, or even pounce on them to arrest people, so they have a short amount of time, you know?" He Siliang said.

"Understood." Yu Jingque nodded and said, this sentence can't be said by Wan Qun, it seems that He Siliang is teaching Wan Qun a lesson.

He Siliang continued: "A skilled radio staff member needs to memorize the password used, but this password is constantly changing, so the radio staff is required to keep memorizing new passwords. ”

"Can't he just take care of it?" Yu Jingque asked.

"Looking?"

"If he had followed the report, I could have caught him ten times." He Siliang thinks that Yu Jingque and Wan Qun don't know about their communication war at all, it's a race against time, you follow the password to send a report, He Siliang thinks that he can catch this enemy ten times.
