Antique food: The general dotes on his lucky wife

Chen Xi knew that his "speech" in front of the bun shop would have some effect, but he never expected that it would have such a big effect!

The reason why Lin Changqing came back so quickly this time was because of two things. One was naturally because Chen Xi was pregnant, and the other was the secret message he had received before. Someone secretly sneaked into Yunzhou City from the Xishan Trail.

Because the Tiger Roar Camp helped cover them up, there was no way to trace the traces of these people.

After all, Lin Changqing has only been in Yunzhou City for a short time. Even if he has already spread all his people, it will be difficult to dig deep.

So I've been back for a few days, but there's been no progress on the whereabouts of the infiltrated spy.

But on the third day after Chen Xi's "speech", Chen Ji Baozi Shop received a secret letter. The letter pointed out in detail which household suddenly had a few people, their appearance and characteristics, and how strange their whereabouts were. etc!

After Lin Changqing received the news, he immediately sent people to investigate, but he did not expect to gain a lot.

Although it is still unclear which force the person is related to, it is certain that he is definitely not a local in Yunzhou City.

He suddenly appeared in Yunzhou City at this time, and his whereabouts were still secretive. In short, he must not be a good person!

Lin Changqing was secretly watched by people here, and no new discoveries were made after watching for several days.

"They seemed to be waiting for someone's order. They stayed in the small courtyard and did not go out. Except for one person who went to the street regularly to do shopping, the others did not show their heads at all."

Now that the weather is getting hotter, Lin Changqing and Chen Xi took a rest on the couch by the window after eating and washing.

There is a game of chess between the two of them, which is one of their recent entertainment activities.

Chen Xi thinks that although she is not sure now

It is important to determine whether the baby in the belly is a healthy baby, but if it is healthy, she must be prepared to welcome him.

And in order to better educate her children, she plans to start working hard from now on!

She doesn’t understand anything about early childhood education, but she feels that if she reads more things that are elegant and wise now, her children will be able to be more elegant and elegant in the future, right?

So when she had nothing to do, she read during the day. Now that it was getting late and it was not time to go to bed, she took Lin Changqing to play chess.

She doesn't know how to play Go, but she knows backgammon and reversi, and Lin Changqing has never heard of backgammon and reversi. She has an absolute advantage, so naturally she wants to drag him to play these games.

Lin Changqing would never refuse her, and now that he heard her remarks about "prenatal education", he would not refuse even more. He would do whatever Chen Xi said.

However, whether it was backgammon or reversi, it was too simple for Lin Changqing. Within two or three days, he had already mastered it with ease. If it weren't for Chen Xi's fear that losing too hard would affect his mood or affect his prenatal education, thereby affecting the child. , he will definitely kill everyone!

So when he was playing chess in the past two days, he would deal with the secrets collected from various places while taking time to play chess for Chen Xi, doing both.

He had just read a secret letter, which contained news about the people he had recently monitored. After reading it, he couldn't help but shake his head and sigh.

After Chen Xi made a move and blocked Lin Changqing's layout, he raised his head and asked, "Has no one contacted them during this time?"

Lin Changqing quickly glanced at the chessboard and dropped a piece.

"No, the one on the street

After observing these days of purchasing, there is absolutely no chance of passing on information. The people he purchases from are all nearby farmers, and they do not set up stalls every day. It seems that he chooses randomly and is just purchasing. "

Chen Xi asked again: "Is it possible that there is no need to rely on text to send messages? For example, if the person buying radish eats radish today, the person in the dark will know that nothing happened when he sees him buying radish. If he buys cabbage, Then the person in the dark knows something is going on at a glance?"

Lin Changqing couldn't help but be stunned and began to frown and think.

Chen Xi didn't bother him either.

The TV station always shows some spy movies, and Chen Xi likes to watch them, so she knows that handwritten letters are not needed to convey news. Sometimes walking on "Ping'an" Street today means "safe", and walking on "Fengtai" Road tomorrow , which means "the wind is tight and withdraws"!

In addition, for example, if a pot of flowers is placed on the windowsill, it means that nothing is going on and the connection can be made. If there are no flowers on the windowsill, it means that "there is a mole and the transaction is cancelled"!

…………

Anyway, there are all kinds of communication methods. Chen Xi has seen countless communication methods since he was a child. When he heard Lin Changqing said that he had not caught the communication method, he immediately thought of these.

Lin Changqing seemed to be interested and started writing a letter on the paper. Chen Xi did not urge him to play chess and turned around to get the cut fruit to eat.

When she saw Lin Changqing had written the letter and put it in an envelope, she also handed him a piece.

Lin Changqing bit the fruit and pulled the thread. Then the bell rang outside the door, and Dong Baozhen immediately appeared indoors.

"Give this letter to Acropolis."

"Yes."

After Dong Baozhen went down, Lin Changqing continued to put herself down again.

Fill in that move.

"You are still smart. If it weren't for you, I might have missed this point. Let's go back and ask them to watch more carefully!"

When Chen Xi heard this, he instantly became interested.

"Actually, you don't have to handwrite a message to send a message! There is also a more hidden way to send a message. For example, we both have an identical book in our hands, and the layout of the book is the same. In this way, I I can just write you numbers, such as one seven, twenty nine, something like this, which means, the seventh character on the first night, the ninth character on the second page, you have received my message, just compare it The book already knows what it means, but if someone else receives the secret message, as long as he doesn't know which book our code book is from, even if he knows the method of transmitting the message, even if he is killed, he will not know what the secret message means. !

In addition, another convenience of sending messages like this is that people will not be able to change the secret message easily. For example, if I want to send you a letter, if it cannot be sent directly to you, I can only send it to many people. If it reaches your hands, then when the superstition is conveyed, I don’t know how many people will pass through it, and there will definitely be a risk of leakage. But if we convey the message in this way, the other party dares to change a number. Then you can take a look In the code book, I found that this paragraph cannot be connected into one paragraph, that is, someone changed the secret message, and also found out that someone rebelled or something happened along the way of transmitting the message. Isn’t it very useful? "

Chen Xi didn't have the opportunity before, but now that she has such an opportunity, she can't wait to tell all the "interesting" ways of sending messages that she knows.

But because she saw Lin Changqing writing a letter today, she mentioned the "code book" method of sending letters.

And Chen Xi knew that the method he mentioned was only the simplest. As long as the use of the codebook as a communication method matures, more communication methods will definitely be developed!

She could see that as she spoke, Lin Changqing's eyes became brighter and brighter, and his expression became more and more excited!
