Chapter 358 Disadvantages of the Telegraph
"Okay, I'll think about it now!"

Ying Zheng nodded, then he thought for a while, and then ordered a soldier to speak.

"Get your horse ready and ride it to Gongshu Shangzao. Go now. When you get there, bring me what I want!"

"But what do you want, Your Majesty?"

For a while, the soldier said to Ying Zheng in embarrassment, carefully watching Ying Zheng's expression, for fear that Ying Zheng would get angry.

And win politics.

He smiled and signaled him not to be afraid.

"Well, don't worry, you just hurry over there. After you get there, the telegram has already been sent, and Gongshu Shangzao will know what I want!"

"Okay, let's go, my subordinate!"

The soldier did not dare to neglect, and hurriedly mounted his fast horse, and then quickly went out. As he passed by, Ying Zheng immediately said to Ying Changsheng who was aside.

"Now that the soldier has set off, he doesn't know what we want, and he is riding a fast horse. When he arrives, Gongshu Shangzao will definitely not be able to receive the information sent by others, right?"

"That's natural, time is too late!"

The ministers next to him nodded their heads.

Ying Zheng nodded slightly, then looked at Ying Changsheng.

"You have to be clear, kid, whether this machine is feasible or not is now!"

"Father, you should tell me what you want first, so that I can send him a report!"

Ying Changsheng said to Ying Zheng with some embarrassment.

After hearing this.

Ying Zheng was also unambiguous, he said directly.

"What I want is nothing else, but to let Gongshu Shangzao, quickly take out my own, the official badge that I am carrying on my body at this time, and let the soldiers bring it over!"

"I see!"

Ying Changsheng understood, and then he sat down, quickly checked the code table, found a few words, started the generator according to the symbols corresponding to these words, and quickly sent it to the public transport in the distance. telegraph.

The moment the telegram was sent.

Gongshu reacted when he was in a hurry, and Ying Changsheng said something about Ying Zheng.

"Okay, it's been sent, and his things will be delivered later. By the way, he may have a reply later!"

Sure enough, it didn't take much time.

The telegraph rang.

I only saw the regular and crisp iron knocking sound in the air.

a time.

All the ministers couldn't help but be amazed.

At the same time, Ying Changsheng said to them with a straight face.

"Don't talk, don't talk, keep quiet, otherwise I can't hear the specific content of his message!"

While talking, Ying Changsheng quickly recorded the frequency of the transmission.

Then translate it against the code table.

Then I saw Ying Changsheng talking to Ying Zheng.

"Father, Gongshu Shangzao sent back and forth calls. He said that he didn't carry his official badge, and he didn't have anything else on him, so he had to ask the soldiers to send his jade pendant over!"

"Is this really the message he replied?"

It was inevitable that Yingzheng let out an exclamation.

Ying Changsheng nodded.

"As long as there are no mistakes, it must be the message he replied. If you don't believe it, after the soldier returns, ask him if he will know?"

Ying Zheng's voice fell, the moment it fell.

The important ministers on the side nodded one after another.

At the same time, after a while, the soldier returned. After seeing a soldier return, he knelt down and saluted Ying Zheng.

"Your Majesty, Gongshu Shangzao said that no one owns his official title card, so he had to hand over the jade pendant that he carried with him to the villain and bring it to His Majesty!"

"Is this really possible?"

For a moment, everyone inevitably let out an exclamation.

Well, everyone was shocked. The reason is very simple. After all, who would have thought that such a point would be able to carry out long-distance communication. In this era, all of this is tantamount to fantasy.

It is nothing short of shocking to everyone.

Even Ying Zheng couldn't help but gasp.

Then he couldn't help but let out an exclamation, and he opened his mouth to speak.

"Sure enough, it is a divine weapon. With such a magical weapon, I, Daxian, will no longer suffer from the difficulty of information transmission in the future!"

After Ying Zheng's voice fell.

Ying Changsheng on the side nodded slightly.

Immediately he said to Yingzheng again.

"What the father said is true, but I still have one thing to report to the father, that is, although the electric shock is easy to use, it has a shortcoming. Please listen carefully to the father." go down!"

"What's the downside?"

After Ying Changsheng's voice fell, everyone inevitably showed curious expressions.

Well, everyone wants to know.

What kind of disadvantages does this telegraph opportunity have?And such a good thing, if its shortcomings are too big, then it cannot be implemented. If its shortcomings are not too big, it can be promoted in Daqin and used to convey information.

At the same time, looking at everyone's confused expressions, Ying Changsheng was unambiguous and spoke directly.

"The problem is not other problems. The problem is that although it can transmit information quickly, it needs copper wires to connect so that information can be transmitted. That is to say, every place he passes along the way needs to be laid with wires!"

"This wire is made of copper, isn't it?"

The moment Ying Changsheng's voice fell.

For a moment, everyone's unavoidable expressions changed slightly.

Well, everyone realizes that this problem is indeed serious.

the reason is simple.

Copper was a scarce metal in ancient times, let alone ancient times.

Even in later generations.

Copper is still an extremely scarce and extremely precious resource.

Copper prices are still very high.

Under such circumstances, when I heard that the telegraph was going to lay copper wires.

After being able to transmit information, everyone frowned unavoidably for a while.

After hesitating for a while, Ying Zheng looked at Ying Changsheng in front of him.

"Changsheng, I ask you, do you have to use copper wire for this? Is it okay to use iron wire?"

Ok.

Ying Zheng thinks that since copper is fine, then iron should be fine too.

Compared with copper ore, which is expensive and scarce, iron ore is no longer an expensive resource in the Qin Empire, and the price is much cheaper than copper ore.

Under such circumstances, it is quite normal for Ying Zheng to make this suggestion.

However, the moment Ying Zheng's voice fell, Ying Changsheng couldn't help but frown, then looked at Ying Zheng, then shook his head and said.

"Compared to copper, iron is really not suitable for use as a wire, because its conductivity is too low!"

"Then according to your kid's words, what other things are suitable besides copper?"

After hearing what Ying Changsheng said, Ying Zheng couldn't help but frown.

He opened his mouth and asked.

Ying Zheng's voice fell to Ying, and Chang Sheng also began to think carefully in his mind, what metal can replace copper.
