Daming: The system rejected my request for salted fish

Chapter 147

"Just like water ripples, they gradually dissipate as they propagate, so once the distance is too far you can't hear them."

"And this walkie-talkie converts these sound waves into electromagnetic waves that can travel farther and be received by another walkie-talkie."

To be honest, Wei Wu's scalp felt a little numb when he talked about this.

Because in order to explain something clearly, too much physical knowledge is involved.

But the good news is that all the craftsmen were attracted by the novel things he said.

They were like hungry children, greedily wanting to suck the milk of knowledge from Wei Wu.

However, their greed was interrupted by a sudden sound.

The reason was that Song Zhong's voice suddenly came from the walkie-talkie in Wei Wu's hand.

"Hello, hello, 123, Aibisi, Wantu Wantu, Sir, Sir, can you hear me?"

Hearing Song Zhong's somewhat nervous and expectant voice on the intercom, the classroom became quiet again.

Then Wei Wu picked up the intercom and said:

"I heard it, I heard it, where are you now?"

"Hello, hello, 123, Aibisi, Wantu Wantu, Sir, can you hear me? Sir?"

"I heard you. Don't get bitten like me. Speak normally."

"Hello, hello, 123, Ai Bisi, Wan Tu Wan Tu, Sir, what's going on? I can't hear you!"

After hearing this, Wei Wu finally understood what had happened.

He had just forgotten to tell Song Zhong that he should release the intercom button after speaking.

Just as Wei Wu was thinking about whether to send someone to inform Song Zhong, a voice came from the intercom again.

"Sir, if I hold this thing down, you can't speak. Let me try releasing it first."

Yo ho!

Song Zhong is a guy who thinks pretty quick!

Hearing Song Zhong's words, Wei Wu's eyes lit up and he couldn't help but praise him in his heart.

After waiting for a few seconds, Song Zhong's voice did not sound, so Wei Wu immediately pressed the call button.

"Song Zhong, did you hear that? You have to release the button after you finish speaking. Also, tell me where you are and how far away you are."

"Sir! Oh my God! I really heard Sir's voice. This, this, this is amazing!"

"Okay, stop making a fuss and start by talking about your current distance."

Hearing Wei Wu's voice, Song Zhong quickly adjusted his mood.

"Sir, I asked Guardian Zhang to take me on horseback for a long distance, about four miles, and I never thought I would actually be able to speak to you!"

"Alright, alright, come back now that you've tried!"

After finishing the conversation with Song Zhong, Wei Wu looked at the other craftsmen.

"Anyone else want to try it for themselves?"

After receiving Wei Wu's order, Song Zhong rushed back not long after.

Then, with a yearning for new things, the craftsmen lined up one by one to try out the walkie-talkies.

Seeing this, Wei Wu simply handed the thing in his hand to them and let them experience it themselves.

About half an hour passed like this, and when it was almost time, Wei Wu took back the walkie-talkie.

However, the craftsmen's curiosity about walkie-talkies was obviously not something that could be easily dispelled.

After Wei Wu took it back, Sun Chang couldn't help but stand up again.

"Sir, you just said that this intercom can convert sound waves into electromagnetic waves. What are electromagnetic waves?"

"Electromagnetic waves... I've explained this to you but you still don't understand. Your foundation is not strong enough and you need to learn."

After saying this, Wei Wu motioned Sun Chang to sit down, then he looked at everyone and said:

"Having seen the magic of walkie-talkies, do you still think a boat without wind, sails, or oars can't move?"

"The ancients were able to create wooden magpies and wooden oxen and horses. Now we can create steam engines that can make ships move without wind."

"But I can't do this alone. I need you to cooperate with me and create it together."

In fact, to be honest, even after seeing the magic of the walkie-talkie, the craftsmen still had little confidence in the steam engine.

Because the walkie-talkie and the steam engine Wei Wu talked about have absolutely nothing in common.
