It turned out that when Qi Yunsheng stood up with his hand on the stone he was sitting on just now, his hand that seemed to only support the stone completed the other two movements. One is to pull out the earphone plug from the Walkman with the middle index finger, and the other is to press the recording key of the Walkman with the thumb.

From the perspective of the crowd in the distance, it was impossible to see that the Walkman had been left behind by him.

He saw the people getting closer and closer to the stone, and in order not to expose the Walkman, he had to use the proprietress to drive them away, even if this would cause the Walkman to record a lot of information.

Being able to directly use the Walkman recording trick, Qi Yunsheng secretly called it a fluke in his heart. Because today he's listening to a song on a ripped cassette. All original tapes have two small protective bezels at the bottom to prevent the original sound from being erased if the recording key is pressed by mistake. This rip tape has long since removed the bezel and can be recorded at any time.

After Qi Yunsheng straightened the Walkman, he first canceled the recording, then poured a little tape, then plugged in the headphones, and pressed the start button to calm down and listen carefully.

The recorded sound is a bit muffled, but tellable. First, an old man's voice said something like the view.

A young man's magnetic voice asked: Are you hungry, do you want to eat?

A child's sweet and crunchy voice says, "I'm hungry and want to eat a burger."

Then there is the sound of tearing the package, the sound of chewing food.

The voices were getting clearer, probably because they were eating and walking, getting closer and closer to the Walkman.

After a while, his master's voice appeared.

"It's over, it's fun! Do you want to hear me tell you a story about the poison in the? ”

Qi Yunsheng heard this voice, and his master's smiling face seemed to appear in front of him along with the voice.

A rough voice came out: "What about other people's eating, don't be disgusting!" ”

He thought it was the strong man who said it.

After a while, the child's voice appeared: "I'm done, Grandpa Huang, you can speak." ”

The laughter of the crowd could be heard in the headphones.

His master's voice appeared again: "Good! One day, a young man went to the police station to report that someone had poisoned him......"

At this time, the boss's scolding appeared, interrupting his master's words.

Then there is the sound of people running, the sound of the car door closing, the sound of the car starting, the sound of the car starting, and so on.

Qi Yunsheng pondered for a while, rewound and listened again, and then he cast his gaze to the place where his master was.

He came to the forest where his master, stood in front of the poop, and observed.

There were no pieces of paper or anything like that to write down words around.

There are no meaningful traces on the ground.

He picked up a stick and unfolded his master's used toilet paper, which had nothing but on it.

"I don't think Master has the ability to erase a line of words when using toilet paper." He thought with a wry smile.

With a sigh, he reluctantly stuck his stick into the.

The is a little thin, and it seems that his master's stomach problem is a bit of a flare up. He stirred it a few times, and a thin thread appeared on his stick. He slowly pulled the thin thread and the ball of thread connected to it away from the soup area, and then turned back and carefully examined the dirt on the ground with a stick, so that it could fully reveal its contents, and found nothing else hidden inside. Then he carried the thin thread with a stick to the stream at the foot of the mountain in the distance, and used the stick to carry the water to rinse the thin thread repeatedly.

After washing, he picked up the thin thread ball with his hand and observed, only to see that there were hundreds of tied thread buckles and thread knots on the thin thread.

Qi Yunsheng first wrote twenty-six English letters on the ground, and then wrote the Arabic numerals from one to twenty-six under the letters in turn.

Qi Yunsheng found the thread of the thread, closed his eyes, and used his left thumb and index finger to twist the buckles and pimples on the thin thread one by one, while still reading something with words in his mouth. After reading for a while, I opened my eyes and wrote a few strokes on it. In a few moments, he finished twisting the whole ball of thread and wrote a line on the ground.

Ten years ago, when Huang Banxian first bought Qi Yunsheng, he worked hard to educate him for a while. This is also the happiest and happiest time he spent with his two apprentices.

At that time, Huang Banxian happened to be interested in cryptography knowledge, so in order to increase Xiao Qi Yunsheng's enthusiasm for learning, he invented a cryptographic game based on the basic principles of cryptography. To put it bluntly, this game is to record a piece of text with a rope. It not only exercised brain power, but also exercised the dexterity of fingers, and the master and apprentice had a lot of fun at that time.

The principle is simple:

For example, the numbers of a, b, and c are 1, 2, and 3 respectively, so that x, y, and z are represented by numbers 24, 25, and 26 respectively.

In this way, all the phonetic letters can be converted into numbers. For example, the word "tie" is replaced by pinyin is bang, and then replaced by the corresponding numbers is 2, 1, 14, 10.

The next step is to represent the numbers with rope knots and knots.

Use a large buckle to represent 10.

Use a small clasp to represent 5.

Use a small pimple to represent 1.

For example, the same word "tie" is expressed in the form of a knot: two small pimples (2), a small pimple (1), a large ring buckle plus four small knots (14), and a large ring buckle (10).

In fact, the difficulty is to be familiar with the other party's knotting habits. For example, what should be the knot spacing between words, what should be the knot spacing between letters and letters, what should be the spacing between the interlocks and pimples inside the letters, etc., only two people who often communicate with knots are familiar enough to reach a tacit understanding that can carry out unmistakable communication on the rope line.

Of course, this method can also be simplified, but it is necessary to remember the simplified method in particular, and it is easy to forget it after a long time. Although the above method is cumbersome, you don't need to memorize, and it's okay if you don't use it for a long time, once you get a string to record the text, you can know the meaning if you think about it.

After Huang Banxian was hijacked and his mobile phone was taken away, he was thinking hard about how to get out and how to convey a message to Qi Yunsheng. He came up with three ways. The first is to find a way to get a spare mobile phone at the residence and secretly call or text the apprentice. The second is to find an opportunity to get a pen and paper to write a note, and find an opportunity to hand it over to the apprentice, such as asking the proprietress of the small restaurant in Hetou Village to hand it over, etc. The third is to convey information in the current way of keeping notes without pen and paper.

He even considered a fourth way: that is, without pen and paper, he wrote a blood book on his clothes at night, with Qi Yunsheng's mobile phone number written on it, and then wrote "100,000 urgent, life is at stake!" Please call this number and tell us the following information and you will save someone's life. "Then when you go out the next day, look for an opportunity to throw it to others. But in the end, because there was too much content to write, he was afraid of pain and had to give up.

In the end, he decided to try each of the first three, regardless of the difficulty.

Unexpectedly, the situation was even worse than he expected.

Yin Zhaojing was much more difficult to deal with than he thought. This young handsome guy is as thoughtful as an old bird who has been walking the rivers and lakes for many years, and he is strictly guarding Huang Banxian and being on guard everywhere.

He let his big bodyguard follow Huang Banxian, and he was inseparable. Huang Banxian had no chance to touch anything like pen and paper.

That night, it was cold in the mountains, and everyone slept with a thin quilt. Huang Banxian lay on the bed and snored for half a night. In fact, he has been constantly thinning the threads on the quilt, then planning the information to be expressed, and then compiling it into an expression with knots, and then tying them out one by one with a rope. It's easy to say, but it's quite tiring to do. By the second half of the night, he was physically and mentally exhausted, and he was almost exhausted.

When he was done, it became another problem for him to hide the thin thread there. In the end, he adopted the usual method used by drug smugglers and prison inmates, and put it in the place where it was to be pulled out during the day.

Tossed all night, of course he couldn't get up early the next morning. On the other hand, he didn't want Si Lei to pay attention to his bed, because he had dismantled the thin quilt.

As for the request to go to the residence to change clothes in the morning, first, he really needs to change clothes, and second, he still wants to try if he can use his mobile phone, after all, it is very uncomfortable to have a ball of thread in the back from time to time.

Yoon Zhaojing's overreaction surprised him a little.

Yin Shuai actually asked him to strip naked for a body search, although it was a euphemism in the name of taking a bath, but Yin Zhaojing's determination and seriousness still made him worried.

After eating in the morning, he took out the medicine bottle and poured out a stomach medicine and ate it. In fact, this is a laxative mixed in stomach medicine, which is one of the things he usually defends himself. Everyone was ready to stop and drive on the road.

Although Si Lei was driving along the way, Huang Banxian, who was actually guiding the way, was always in control of time and progress. When entering the boundary of Hetou Village, he let out a few loud farts at the right time, and then asked to go to the toilet.

Let the car drive through the village and let Huang Banxian go to the toilet in the woods on the other side of the road, these are all requests made by Yin Shuai. And the whole process is monitored by Si Lei, and he is not allowed to come into contact with anyone.

As soon as he got out of the car, he saw Qi Yunsheng sitting on a stone twenty or thirty meters away. He didn't even look at his apprentice squarely. He felt that his apprentice was clever enough, but in the end, whether his apprentice could successfully discover and get the stinky thread group letter was left to fate.
