Looking at the frames of the room, Lin Feng had completely imagined the scene after the decoration. After looking at the house, I went to the front yard to find Steward Hu, and arranged for him to send some cowhides, small bamboo tubes with the thickness of my arms, and cotton threads to the guest room where Lin Feng temporarily lived, and I went back first.

After waiting for Steward Hu to send these over, Lin Feng started another interesting thing, if this achievement was dedicated to the emperor to play, it would be another great achievement!

Cut the bamboo tube, seal the cowhide to one end of the opening, make these two, and then use a fifty-meter cotton thread, through the two bamboo tubes, and fix the thread at the bottom of the cowhide. In this way, a local telephone was made. It's quite simple to say, but it's more troublesome to really do, the bamboo tube has to be picked well, and the incision has to be smooth. The cowhide can not be thick or thin, and it must be sealed tightly when sealing, and there can be no loopholes.

Anyway, according to experts in the 21st century, this kind of earthen telephone is the earliest and easiest to make, and it is a stress-free call within 100 meters! I didn't have a chance to try it before, but now in this era, if this thing can really be used, it is simply a communication artifact!

After making the first phone, it was almost noon, and it happened that Zhou Chen and they were all arranged out today, and now I want to try the practical value of this local phone and I can't find anyone. Lin Feng was sitting in a chair, looking at the earthen phone on the table, thinking about whether to make one or do something else.

"Brother Feng! Open the door, it's me! Just as Lin Feng was thinking, Xiao Yun's voice came from outside the door.

Lin Feng instantly jumped up excitedly and ran to the door to open the door, then pulled Xiaojun to the table and handed her a bamboo tube, and then pulled her to the door: "You take this!" After finishing speaking, Lin Feng didn't wait for Xiaojun to answer, so he ran away with another bamboo tube.

At a distance of about fifty meters, after the cotton thread was straightened, Lin Feng said to the bamboo tube: "Hey? Feed! Xiaojun, can you hear me? Then he looked up at Xiao Kun, only to see Xiao Yun holding the bamboo tube and looking at it, Lin Feng couldn't help but feel happy, it seems that there is still something to believe in what the experts of the twenty-first century said.

Then Lin Feng put away the bamboo tube and ran back, and when he came to Xiaojun, he asked, "Did you hear me call you just now?" ”

Xiao Su nodded suspiciously, tilted his head to look at Lin Feng and said, "Well, I heard it!" What are you giving me? ”

"Come, go in!" As he spoke, he pulled up Xiaojun and went back to the room, then pointed to the chair next to the table and said, "Sit, I'll tell you slowly!" Then Lin Feng removed the fifty-meter cotton thread and replaced it with an eighty-meter-long cotton thread.

Lin Feng explained to Xiaojun while changing the cotton thread: "This thing is called a local phone, a tool that can make two people talk from a distance!" Saying that, Lin Feng suddenly thought of something, stopped the movements in his hand, looked at Xiao Kun and said, "Xiao Kun, why do you say that every time you appear, you can bring me good luck?" After finishing speaking, he reached out and touched Xiaojun's hair, looking at her and smirking.

Xiao Yun also pursed his lips and smiled, reached out and knocked Lin Feng's hand away, picked up the teapot on the table, poured a cup of tea for Lin Feng and handed it to him: "Here, drink some water!" Look at your mouth that's going to crack dry! Also, don't touch my head in the future, I'm not a kid again! ”

Lin Feng took the cup and took a sip, nodded and said, "Okay!" I'll pay attention later! Wait a minute, experiment with the phone and see how far it can travel! "Xiaojun is very good at this, she is very understanding, she never asks much about what Lin Feng does, she just stands silently behind her.

After trying the 80-meter line, Steward Hu came to call them for lunch, and after eating, he tried the telephone for nearly an afternoon, and finally determined that under normal circumstances, the farthest communication distance could reach about 160 meters. Today's discovery was a major turning point in the military in the future.

After doing everything, it was almost time for dinner, so he simply packed up the materials, and then Lin Feng and Xiaojun went to the front together. When he was on the road, Lin Feng said to Xiaojun while walking: "Xiaoyun, don't mention today's matter to anyone for the time being!" Including Xiaofeng and your father! I've kept this thing for other purposes! ”

Xiaoyun waved her arms back and forth and replied, "Well, it's okay, I promise not to mention this matter to anyone!" You can rest assured! Brother Feng, do you have anything to do tomorrow? ”

After hearing this, Lin Feng glanced at Xiao Su beside him, and didn't understand what she wanted to do, so he asked casually: "There are no arrangements for the time being, what's wrong?" What's the matter with you? ”

Xiaoyun turned his head and glanced at Lin Feng dissatisfiedly, and then said a little angrily: "What? Can't I ask you if it's okay? Can't I look for you if it's okay? Look at you, I didn't have the opportunity to walk around the city before. But now, you're a festival envoy, and you're an earl! Why, haven't you thought about accompanying me to go shopping and buy something? It's going to be the New Year in a few days, are you not taking me seriously at all? ”

Listening to Xiaoyun say so many words in one breath, Lin Feng realized that he had indeed been a little too busy recently, so he snubbed her. Lin Feng hurriedly took Xiaoyun's hand and explained, "No, no! It's not what you say it is! Originally, I was going to pick you up tomorrow morning and want to surprise you, so I didn't say it! I know it's almost the New Year, and yesterday I asked Steward Hu to send more money to the people for the New Year! Aren't I going to surprise you tomorrow! ”

"Really?" Xiao Yun turned around, raised his head and looked at Lin Feng with a look of disbelief!

"Uh-huh!" Lin Feng nodded vigorously, and stretched out his right hand: "I swear, what I just said is true!" Do you believe it? It's really not what you think! ”

"Alright, don't swear!" Xiao Yun stretched out his right hand and pulled Lin Feng's sworn hand down, then looked at Lin Feng and said, "Then it's decided?" You're coming to pick me up tomorrow morning! ”

"Trust me!" Lin Feng patted his chest and promised: "I am L'Oréal Paris, worthy of your trust!" After finishing speaking, he didn't care about Xiaojun, who looked puzzled, and pulled her into the living room.

After entering the living room, I saw Zhou Chen and Mao Hao sitting there smiling and chatting with tea. After seeing Lin Feng and the others come in, they stood up together with a smile: "Boss! Then he looked at Xiaojun and said, "Hehe, my sister-in-law is also here!" ”

Xiao Yun greeted the two of them generously, Lin Feng walked to the table and poured a cup of tea, looked at the two of them after taking a sip and asked, "How are things going?" ”
