"Listen to me, now the party-state is short of talents, so we focus on cultivating you, radio is an indispensable communication tool for engaging in secret work, you have to study hard, these wireless telegraphs have a very important role in collecting intelligence, and they are an advanced technology brought back from the United States. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info "Purple Rose said solemnly.

"It's so complicated, can I not learn it?" Huang Xiaohua jumped up.

At the Oasis Academy, she felt her scalp tingle when she saw those poems, and now she had to learn what kind of radio was torture for her in disguise.

Don't learn!

Refuse not to learn!

"Miss Huang can't learn, you can let Miss Lu and Miss Liu teach you. Didn't you study like this at Oasis Academy? Dai always had a light smile on his face, and there was no displeasure in his speech.

may be afraid of Huang Chenglin's identity.

Lu Yitian guessed so.

"Miss Huang should also hate traitors the most! After learning these techniques, you can steal secret intelligence, eradicate more traitors, and show your skills for the Republic of China. Day continued.

"Really?" Huang Xiaohua suddenly became interested, and looked at Purple Rose with questioning eyes.

"What Director Dai said is true, you should learn these advanced technologies, this is the most efficient way of communication that Chairman Chiang has painstakingly imported from the United States." Purple Rose's cold face softened a little, and her tone of voice softened.

seems to be afraid that Huang Xiaohua will really refuse to learn.

"Huahua, it's okay, the party-state needs us, we should work hard to overcome all difficulties, and we will study hard together." Lu Yi looked at Huang Xiaohua and encouraged her.

She doesn't like to study poetry and literature, and every exam in Oasis Academy is only possible to pass with Lu Yitian's "great help", and now letting her learn these wireless communications is undoubtedly equivalent to holding a rope to strangle her neck.

"That's right! Huahua, let's study together, if we really can't learn, Director Dai won't embarrass us, right? Liu Yuelang raised her head to ask for Dai's opinion as she spoke.

"Hehe, of course not, you just do your best, but I don't believe that the talented people and talented girls of Oasis Academy will learn these simple things." Dai said with a very simple expression.

"With Director Dai's forgiveness, even if we can't learn and won't be punished, we won't have any worries." Liu Yingzhe nodded and said, and glanced at Liu Yuelang eagerly.

All this did not escape the eyes of the Purple Rose.

"Since Liu Yingzhe has said that we can't learn, we won't be punished, we can learn with confidence." Chen Sixian turned his head to look at Lu Yi's leaning face and said with a smile.

"Huahua, don't worry, don't live up to Director Dai's hard work for us, work hard with us, okay?" Lu Yitian looked at Huang Xiaohua encouragingly.

Huang Xiaohua nodded.

Purple Rose led them into several different lecture rooms.

Huang Xiaohua and Lu Yiyan, and Liu Yuelang were assigned to the same classroom.

Purple Rose told them about the international common radio code and signal, the composition of the telegram, the type of digital calculation, the clear code cipher, the plain language, the simple language, the convention and call sign, the programming of the communication code, etc., a series of professional terms, listening to the yellow smile in the clouds, in the fog. Liu Yuelang and Lu Yitian were also confused and half-understood.

"Do you think it's too difficult?" After Purple Rose finished speaking, she looked at everyone with a smile.

"It's harder than climbing to the sky!" Huang Xiaohua said with a flat mouth.

"Huh! I don't want you to learn so hard, I only teach you to learn some simple telegram code, you can use the telegram code to communicate with the outside world at any time. Purple Rose finished speaking, walked into a secret room and launched a simple portable telegraph.

Each person is then tossed a digital book that resembles an astronomical number.

Lu Yitian picked it up and opened it to see that it was all words and numbers, and behind each word was densely packed with a bunch of numbers.

Ming--& amp; gt; 2494

days--& amp; gt; 1131

....

Big--& amp; gt; 1129

Medium--& amp; gt; 0022

Hua--& amp; gt; 5478

People--& amp; gt; 3046

Country--& amp; gt; 0948”

"You see, these are simple words and numbers, these are the telegraph codes on the telegram, you will understand if you look at them." Purple Rose explained to them as she pulled the telegraph in front of them.

"I understand this." Huang Xiaohua can see clearly at a glance, every 4 numbers represent a text.

Do you know where these numbers come from? ”

"Of course I don't know!" Huang Xiaohua maintained her usual fast mouth.

"Okay, now I'll teach you how to hear the numbers." Purple Rose used an electric key to make a demonstration, and then struck out the dots, strokes, and pauses in between. Let them hear the different numbers.

"Wow! It's so hard. Huang Xiaohua shouted anxiously again.

"You have to be patient, these digital codes are this kind of tone of the radio signal is transmitted from time to time intermittent, they have continuous waves, but if you listen carefully, listen quietly, you will be surprised to find that each point, stroke and pause in the middle has a different representation, the short time of the key represents the point, the long time of the key (three times the length of the point) represents the "stroke", and the hand raised without pressing the electric key represents the interval. ”

Purple Rose taught very patiently, and they learned very hard.

Huang Xiaohua would shout every day, "I won't." I can't get the hang of it. ”

Lu Yitian has the strongest ability to accept, and a week has passed, and she can actually receive the code intermittently.

Purple Rose saw that Lu Yitian's code reception had been initially on the road, so she instructed Lu Yitian to teach Liu Yuelang and Huang Xiaohua, and she went to teach others in other classrooms.

Purple Rose didn't go to another classroom to teach other people, she went back to Dai's office to report on her mission.

Dai was waiting for Purple Rose in the secret room, and when he saw her come in with a relieved face, he knew that she was finished, and gently hugged her and asked, "How is it, is everything arranged according to the plan?" ”

"Everything is ready, only the east wind is owed." Purple Rose kissed Dai's face and said happily.

"Okay, I'll issue a secret order to Nanjing, so that they can intercept the news here at any time." Dai looked very happy, hugged the purple rose and said excitedly, you have worked hard these days, I will definitely work hard to treat you at night. ”
