When dinner was delivered in the evening, the young soldier "accidentally" mentioned that because he had gone to the mountains to carry out a mission last night, there would be no training tonight and the lights would be turned off and he would go to bed early.
The three men were lost in thought when they heard the young soldier's words. Not only were they being monitored by the troops, but they were also observing everyone. Everything seemed normal, and no one suspected them. They hadn't expected to encounter Li Yichen, a special forces soldier who had diligently studied combat experience for decades to come in space. He saw through them after just a few interactions.
After the young soldier left, the three of them ate normally, without any abnormality.
Li Yichen watched them eat while holding his bowl. The more he watched, the more he felt something was wrong. It was not only that these three people had not communicated much all day, but they also did not talk much while eating. This was not the atmosphere in the cave before.
Exit the monitoring screen, click on the playback function, and select the playback time.
I first watched the video of when I just entered the dormitory in the morning. Apart from the fact that the monitoring equipment in the room was exposed during the inspection, there were no other problems.
Then I watched the next time period, and there was still no problem. Then, they spent the whole morning sleeping in separate beds, which was not very interesting.
Continuing to watch the lunchtime video, Li Yichen frowned as he watched: Why are the three Qiang people speaking Chinese while eating? Shouldn't they communicate in their own language? This... Isn't this for them to hear? Did they already know they were being monitored?
Thinking of this, Li Yichen didn't dare to delay and quickly backed up the day's videos. He used the excuse of having to pee and rushed to the toilet with his mobile phone.
I went into the bathroom and checked the squat toilets. After making sure that there was no one else in the men's room, I slipped into the space.
Jiang Shaoming has retired and went back to his original unit for a meeting. He had nothing to do in the rest of the time. Now there was a professional killer named Kikuye in the space. He did not go anywhere for the whole day and just stayed here with the father and son to interrogate them.
Li Yichen entered the space with a bad look on his face and asked them to leave the interrogation room and open the surveillance video recordings of the three people to show them.
At first it seemed that there was no problem, but as he looked at it, Jiang Shaoming frowned.
"Yi Chen, these three people are communicating in code."
!!!
Li Yichen knew that three cobblers can definitely make a difference. Look, his uncle noticed the problem that he hadn't discovered. It was really like a veteran is worth two!
I enlarged the picture and adjusted the playback speed, slowing it down by 0.5 times. When I looked at the problems Jiang Shaoming mentioned, they became very obvious.
The previous scene of three people sitting by the bed and the table and eating normally is gone, and there is only a left hand in the entire picture.
This hand belongs to Ridamuji. He was sitting at the table eating at noon. Because he had his back to his two companions and could not communicate, Li Yichen did not pay much attention to him and only observed the other two people facing him.
Jiang Shaoming attended the Whampoa Military Academy and had some knowledge of cryptography. Coupled with his years of combat experience, he should have been able to crack the code. However, after looking at it for a long time and then writing and drawing with a pen, he still couldn't crack it.
The history of cryptography is quite long. From the ancient Caesar code, Morse code, shed code, pigpen code, and Virginia cipher to modern complex addition ciphers, they are all used to ensure the secure transmission of relevant information.
The most famous of these is probably Morse code, but that's not what they used.
