Zhan Qi smiled, because he couldn't imagine what kind of thousand-mile sound transmission method the paper in the toilet was, but Du Xiaomeng still had a serious look and said that he wanted to study it. The paper used to wipe the buttocks, it is still possible to use it to transmit messages thousands of miles, but thousands of voices? Foolish people talk in their dreams, right?

Du Xiaomeng glanced at Zhan Qi, who was still smiling, and scolded in her heart: Mobile phone, it's a mobile phone! It's not a piece of paper, it's a faint soul!

She waited patiently for Zhan Qi to finish laughing, and then said slowly: "I'm not talking about the toilet paper, it's a machine in your hand." ”

Hearing her say this, Zhan Qi became interested and asked, "The machine in your hand?" What is a machine? ”

"This ......"

Du Xiaomeng thought about it for a while, and felt that it was difficult to explain it clearly just by saying or just comparing it with his hands. So, she said, "Give me a pen and paper, and I'll draw it for you." ”

"Good!" Zhan Qi, who was aroused by Du Xiaomeng's curiosity, responded happily, and immediately got up and went out to get paper, pen and ink. After a while, he came back with a stack of paper and a brush and ink.

He excitedly put the paper, pen and ink on the edge of the table, and then diligently put a piece of paper in front of Du Xiaomeng. Seeing that the light in the house was insufficient, he hurriedly shouted out: "Liu Lu, light the lamp!" ”

Liu Lu outside the door hurriedly trotted in, lit a lamp and put it on the table. When she saw the pen and paper on the table, she was curious, but because of the general's presence, she didn't dare to ask casually. Seeing that Zhan Qi didn't mean to let her out, she hurriedly stood behind Du Xiaomeng and waited to see what kind of medicine was sold in her wife's gourd.

With the help of the light, Du Xiaomeng saw that there were three faint, small green bamboo leaves in the lower right corner of the paper placed in front of him, and a red mark was printed on the bottom of the bamboo leaves. The paper was about the same size as a modern A4 paper, and when she touched it, it felt no different from ordinary printer paper.

When she touched the paper, Zhan Qi had already started grinding the ink, and then handed the brush covered in ink to Du Xiaomeng.

Du Xiaomeng took the brush and wrote the word "mobile phone" on the paper, and she wrote the traditional machine character in one go without difficulty. The reason why she can write traditional Chinese characters so smoothly is due to the fact that her biological father's eldest wife is willing to spend money to send her to school. After studying in Hong Kong for five years, I saw that my eyes were full of traditional characters, and I couldn't even think about whether I could read or write.

However, although the characters are written fluently, she has not practiced calligraphy well, and the two words written by the pen are ugly and ugly.

She pointed to the two words on the paper, looked at Zhan Qi and said, "See?" It's a mobile phone, not a paper paper. ”

After saying that, she continued to work hard and drew the image of her mobile phone on paper. However, after drawing for a while, the paper has been painted black by her, how can there be any shadow of a mobile phone?

Crumple up the paper, throw it on the floor casually, and take another one to continue smearing. After drawing a few strokes, if you are not satisfied, throw it away and replace it with a new one.

Du Xiaomeng's actions made Liu Lu, who was standing behind her, look anxious. She peeked at the general, and saw that the general's brows were not furrowed, and he was engrossed in watching his wife paint. Alas, the general doesn't speak, why is she in a hurry? She resisted the urge to hold her wife, and looked at the more and more papers thrown on the ground with heartache.

When Du Xiaomeng threw the paper, he inadvertently saw the strange expression on Liu Lu's face and asked, "Xiaoliu, what's wrong with you?" Uncomfortable? ”

Liu Lu hurriedly shook his head, propped up a smile and said, "The slave is fine, madam, you can continue to paint." ”

She felt that Liu Lu was a little strange, but she didn't ask any more questions when she was concentrating on drawing her phone, and turned back to continue drawing. If she knew that the paper she was using now was not very expensive, she would understand why Liu Lu's face had a toothache-like expression.

After tinkering for at least half an hour, Du Xiaomeng finally drew a picture of his mobile phone that he felt more satisfied with. She drew a covered mobile phone, which looked like when it was closed and when it was opened. Originally, I wanted to draw a smartphone with a touch screen, but the smartphone is more difficult to explain than an ordinary mobile phone. In order to let Zhan Qi, an ancient man who had never seen a mobile phone, roughly understand what a mobile phone is, Du Xiaomeng finally drew an ordinary mobile phone with a simple style.

After drawing the phone, she solemnly wrote the word "mobile phone" in the middle of the top of the paper. After writing, she put down the brush, held up the paper, and said, "See?" This is the phone. ”

Zhan Qi looked at the strange picture on the paper, his face was full of doubts and disbelief, and asked, "Such a strange thing, can it also transmit sound thousands of miles?" ”

"That's right." Du Xiaomeng nodded affirmatively, pointed to the mobile phone on the paper and explained one by one, "This is the keyboard, this is the display screen." When you press the corresponding number on the keyboard, you can connect to the corresponding person's phone. At the same time, you can use the keyboard to type and send messages to the corresponding smartphone. As long as the other party receives your signal, they can talk to you and send and receive text messages. ”

Zhan Qi listened like a cloud, unable to understand what Du Xiaomeng was saying. Confused, he asked, "What signal?" Call? Short message? ”

Du Xiaomeng said: "To put it simply, if you and another person each have a mobile phone in their hands, then no matter how far apart you are, you can talk to each other and write letters." And you can hear each other's words right away, and see each other's letters right away, as if you were two of you sitting face to face. ”

Zhan Qi was surprised and asked, "Is it possible?" ”

Du Xiaomeng smiled and said, "Everything is possible. ”

Zhan Qi's heart moved. If there really is such a thing, and it is used in marching and fighting, it can take the lead! He took the paper in Du Xiaomeng's hand, stared at the picture seriously, and didn't see any clues after looking at it for a long time. In an inquiring tone, he asked, "Can you really make something like this?" ”

Du Xiaomeng put on an expert appearance and said in an unquestionable tone: "It is still in the research stage. But there are too many problems that have not yet been solved, and it will take time to study and solve them one by one. ”

Zhan Qi was bewildered by her seemingly professional appearance. He asked, "How long will it take to make it?" ”

Du Xiaomeng glanced at him and said lightly: "This is not necessarily. Doing research is not as simple as cooking, and it's impossible to tell you exactly when you'll be able to do it. ”

Zhan Qi thoughtfully lowered his head and looked at the paper in his hand.

Seeing that he was almost fooled, Du Xiaomeng stretched his waist, yawned, and said as if he was very tired: "It's not early, I'm going to sleep, general, please go back." ”

Zhan Qi came back to his senses and asked, "Can I take this mobile phone picture?" ”

Du Xiaomeng waved her hand generously and said, "Take it." ”

Zhan Qi picked up the graffiti that had not yet dried and left the Cucui Garden. Looking at the way he carefully held the paper, he should have become interested in the "mobile phone" that Du Xiaomeng said, and maybe he really expected Du Xiaomeng to study the mobile phone.
