Age of the Mist

Chapter 854 Strange Three Types of Ciphertext
Buzz, buzz.

In the middle of the night, Shi Tiezhu suddenly opened his eyes.

The darkness couldn't block his sight, the gleam of Guanlan's Sky Eye lit up, and Shi Tiezhu looked at the buzzer on his bedside.

Shi Tiexin woke up together: "What's wrong?"

"The frequency band we set has a signal." Shi Tiezhu pressed the button and turned off the buzzer: "The radio station has captured a piece of information and it has been recorded."

"There is really a signal?!" Shi Tiexin said in surprise, "There is also a third front here?"

"Maybe there is no third front, but the encrypted frequency band will not disappear by itself. It is also possible for others to use this frequency band to communicate." Although it was the middle of the night, Shi Tiezhu didn't feel sleepy at all.

On the one hand, he has long developed the habit of falling asleep at any time and waking up at any time, and when he wakes up, he will immediately feel full of energy.On the other hand, there is no big consumption if you have a successful cultivation base. If you don't sleep, you won't sleep. It's nothing.

In the past three years, he also raised some vigilance.

"Strange, at this time, who would use this kind of near-field encrypted frequency band communication?" Shi Tiezhu put on his clothes, strode across the corridor, and walked to the radio room.

Sitting in front of the machine screen and glanced, a short message was indeed intercepted.

Very short, so short that there are no words.

When the content is visualized on the screen, only four dots come out, arranged at different distances and intervals.There are long or short, intermittent or continuous lines in the middle of the small hole.

"This is a special encrypted telecommunication." Shi Tiezhu understood at a glance that he couldn't decipher it, because he didn't know the orientation, distance, and interval between these small holes, and what they meant.

Shi Tiexin also frowned.Through Hei Zun, he also learned some encrypted communication methods, but obviously not including the one in front of him.

So, what is the meaning of this inexplicable text message?
"It seems that we can only find an expert to ask."

Shi Tiexin: "Do you know secret electricity experts?"

"It's not me, it's 'us'. We know a super-class secret electricity expert." Shi Tiezhu looked at the time: "It's almost five o'clock, she should wake up too, let's wait a few minutes and go there."

At [-]:[-] in the morning, Shi Tiezhu knocked on Sister Mengmeng's door.

Shi Tiexin was wondering if it was too early, and if he woke up his sister so early, he would be yelled at.As soon as she opened the door, she saw that Sister Mengmeng had washed up and was dressed neatly, looking like she was about to go out for exercise.

Shi Tiexin was startled instantly: "Does Sister Mengmeng wake up so early every day?"

"I'm getting older, so I can't sleep anymore. Besides, we were all waiting for the next day, and we often assembled in an emergency and ran long distances. We have already gotten used to getting up early." Shi Tiezhu explained a few words in his heart, and then showed a cute smile to Sister Mengmeng. Expression: "Commissioner, good morning."

"Rare, you still know to come and see me?" Sister Mengmeng said while shaking her arms, as if she was going to do a middle-aged and elderly health-preserving Baduanjin at any time: "It's so early in the morning, what's the matter?"

"I intercepted a piece of ciphertext, but I can't decipher it. Please help me to see it."

"You? Intercepted the ciphertext?" Sister Mengmeng couldn't help being happy: "When did you have the ability to intercept the ciphertext?"

"Isn't this something I've been able to do recently? I've been able to do a little bit of things that I didn't know before. Don't make fun of me if you're a political commissar. I think this encrypted communication is still quite strange. Please take a look and don't miss it. thing."

"Okay, bring it." Soldiers put efficiency first, and Sister Mengmeng immediately began to study the small figure.

She rolled her eyes and frowned.He took out another pair of reading glasses, squinted his eyes and looked at it carefully from a distance. After looking up and down for 2 minutes, he suddenly said solemnly: "How did this secret electricity come from?"

Shi Tiezhu explained the cause and effect.He didn't mention Shi Tiexin's situation, but only said that he went to the radio station to mess around and happened to catch the frequency band.

"It happened to happen? It's too coincidental for you." Sister Mengmeng obviously didn't believe it.But after thinking about it, she shook her head again: "No, it's impossible for you to know this frequency band, maybe you just bumped into it by chance."

An exclamation mark lit up on Shi Tiexin's forehead.Listening to Sister Mengmeng's meaning, what's the reason for co-authoring this frequency band itself?
Quickly urged Shi Tiezhu to ask.

Shi Tiezhu: "Sister Mengmeng, what's the reason for this frequency band?"

"This matter is classified, but since you caught up with it, it's okay to tell you, this is the emergency communication frequency band of the Bureau of Secret Affairs."

Shi Tiezhu frowned: "Secret Bureau?"

"The Bureau of Secrets is a secret intelligence department of our country, deeper than other intelligence agencies. It has made great contributions during the anti-imperialist war, but few people know its existence."

"At that time, in order to allow high-speed transmission, high-speed docking, and high-speed response of intelligence and operations, I also had contact with people from the Secret Bureau. Many of the tasks we performed were supported by the Secret Bureau. It can be said that they are very reliable. underground fighters."

"But why did people from the Secret Bureau come to Mars?"

"And the times have changed a long time ago. Even if there is news from the Secret Service that needs to be sent back to Earth, near-field communication should not be used."

"Is it a prank?"

"No, it's impossible. This is the third ciphertext of the Bureau of Secret Affairs. It is the result of joint research by top linguists, mathematicians, graphics scientists, and cryptographers. It has ultra-small size, ultra-high density, and ultra-strong concealment. Ordinary members of the Bureau of Secrets cannot touch or grasp the characteristics of sex, so it is absolutely impossible to be a prank."

Sister Mengmeng looked at this symbol and said with a serious expression: "This kind of high-density information requires special equipment to decompress, and files of different sizes will be decompressed according to the encryption method. There is no special equipment on the Qianjin, and only general-purpose equipment can be used first." Calculation, it takes time."

"Here's a task for you, continue to monitor that frequency band, and even monitor all other communication frequency bands."

"If there is any trouble, report it immediately!"

Sister Mengmeng quickly took off her sports coat and put on her military uniform, showing her sharpness: "First-class sergeant Shi Tiezhu, we may have encountered some unexpected situations. Now, with you and me as the limit, enter the battlefield Temporary status! Before the situation changes further, remember to act in secret."

Shi Tiezhu was awe-inspiring, and stood at attention in a standard way: "Yes!"

Sister Mengmeng rushed to decipher the third ciphertext, and she wanted to mobilize the computing power of the central computer of the Advance Number to decipher it.

Shi Tiezhu went back to monitor the wireless frequency band.He must remain on the lookout until the situation becomes clear.Can't ask questions, can't respond, avoid exposing one's own existence, leading to unpredictable changes.

There is no problem with other frequency bands, all communication is normal, but this frequency band is strange.

Half an hour later, buzzing, the figure was detected.

An hour later, humming, the figure was monitored again.

In the next two hours, the other party will send the same graphics every half hour.Before the graphic is deconstructed, the information size is only 46Bit, and it is like an invisible ghost assassin in the vast telecommunication field.

"This kind of behavior is too strange. It doesn't seem like an intelligence agent should behave when contacting an organization." Shi Tiezhu squeezed it, and asked in his heart: "What do you think this kind of behavior looks like?"

"This kind of behavior is like the intermittent flashes of light in the dark wasteland, or the regular beating of gongs and drums in the fog." Shi Tiexin expressed his opinion: "I think this is calling for help, or It's a warning."

At this moment, Sister Mengmeng's communication came in: "Come to me immediately."

　I encountered an unexpected situation yesterday, which resulted in no chance to code, and I apologize to everyone.All in all, I hope all book friends can take care of themselves and love themselves.Life is precious and never comes back.Don't give up no matter how difficult it is, be a hard-hearted man and shake your fist at the sky.
