If you think about it carefully, there don't seem to be many metals that can replace brass, and the first thing you can best find is a metal, that is.

Aluminium.

Aluminum is a metal that has been used in a wide range of markets in the future, and this metal has been used in later generations to make wires and wires.

It seems that using aluminum instead of brass is a suitable choice, but after thinking about it carefully, Ying Changsheng feels that this method is extremely inappropriate.

Quite unreliable.

The reason is simple, compared to other metals.

Aluminum is a metal that is not easy to handle.

The reason is simple, making aluminum requires a fairly high technical content of this metal.

It consumes a lot of electricity.

It can be made if you want to electrolytic aluminum in the current era.

The cost is extremely high, and.

Aluminum is a metal.

The technical content of its production.

It is also very high, and in such a situation, it is very difficult to make aluminum easily, and the technical difficulty is simply not possible.

Thinking of this, Ying Changsheng had no choice but to shake his head.

He looked at the winning government in front of him.

Then he opened his mouth and said to Ying Zheng.

"It's a difficult thing to do, and if you want to make this thing, the technology and difficulty are too high, and there are only two kinds of metals that can replace brass to make wires!"

"What metal, tell me about it?"

The moment Win Changsheng's voice fell.

For a while, Ying Zheng inevitably showed a puzzled expression, and he immediately looked at Ying Changsheng.

Then he opened his mouth and said.

"Since there is this metal, let's talk about the other two, doesn't that mean we can do without brass at all?"

"However, the price of these two metals is much higher than the price of brass!"

Ying Changsheng was slightly embarrassed, and then opened his mouth to say.

Time.

Ying Zheng was inevitably a little curious, and he turned his gaze to Ying Changsheng in front of him and immediately asked.

"What do you mean? What kind of metal is this? What are these metals? ”

"These two metals are nothing else, they are gold and silver!"

Ying Changsheng explained embarrassedly.

Well, it's not actually brass that conducts electricity best in metal and that way.

The most conductive metals are gold and silver, but these two metals are extremely expensive, and how high they are.

Lofty to the point of humanity, even if understood.

These two metals have extremely good properties, but the problem is that the price of these two metals is too high.

At this moment, the moment Ying Changsheng's voice came out, Ying Zheng inevitably showed a disappointed expression.

Well, the price of these two metals is too high, and it is so high that the Great Qin Empire at this time simply cannot use these two metals to replace brass for use.

At this time, Ying Zheng was a little disheartened.

I saw that Ying Zheng inevitably sighed, and then opened his mouth to say to Ying Changsheng in front of him.

"It seems that in the future, I Daqin can only use this brass to make this wire, and lay telegraph lines through this brass highness, so that information can be transmitted quickly!"

The moment the voice of the winning government fell.

For a while, the ministers next to them inevitably showed solemn expressions, only to see them frowning at Ying Zheng and saying.

"But Your Majesty, now, I don't have much brass up and down in Daqin, if you use this brass to lay wires, how much money and food will it cost to be able to get to this point?"

The moment the voices of the ministers on the side reached Ying Zheng's ears, Ying Zheng inevitably frowned, and the reason was very simple.

This question.

It really needs to be considered, because the technical difficulty of the production of non-ferrous metals is itself much higher than that of iron.

In their opinion.

If you lay the wire with brass, in that case.

The financial pressure on the Great Qin Empire will suddenly increase countless times.

The reason for this is because of the Great Qin Empire at this time, the brass shell is not only a metal, it also assumes the function of currency.

Brass, which is used as currency, if consumed on a large scale, will only lead to one consequence, and this consequence is.

In the market, there is a large reduction in currency.

Moreover, the use of brass for electrical wiring can also lead to serious security problems.

Well, that's not to say.

In the long ancient times of China, the price of copper was extremely high.

He's always used it as currency.

In such a situation.

Once, use brass as a metal to lay wires.

That leads to a problem.

That is, there will definitely be a large number of people in the people, and a large number of lawbreakers will secretly cut off the wires, and then melt them and sell them for money.

Well, that's not to say.

Stealing wires is not just something that happened in ancient times.

Even in the Hereafter.

The price of copper is already very low, it is not so high, but even then, there are still a lot of people who steal a lot of wires.

And then sell it, sell it to those scrap yards to make a profit.

In such a situation.

It is conceivable that if brass is really used to lay wires.

It will definitely give rise to a large number of criminals to commit theft.

Their theft is a small matter, the most important thing is.

It will interrupt the transmission of information from the Great Qin Empire.

Especially in this era of backward productive forces, in this era of backward investigative methods, it is simply difficult to succeed in catching those who stole wires or preventing this kind of thing from happening.

Because judging from the efficiency shown by the Qin Imperial Court in the process of arresting those wanted criminals from the Six Kingdoms.

If the Great Qin Empire wants to catch criminals, it is actually an extremely difficult thing.

In such cases, brass is used to lay the wires.

It's a bit embarrassing.

At this time, after the ministers said what they were worried about one by one, they won the government for a while, and inevitably showed heavy expressions.

All right.

Things have come to this point.

Ying Zheng found that although this telegraph was good, although he could transmit information from thousands of miles away, his shortcomings were too great.

How big is it?

The winning politicians of the Great Dao are a little tempted to choke on food.

I didn't continue to push this telegraph.

At this moment, I only saw Ying Zheng, and I couldn't help frowning and said.

"The cost of wires is too high, with my Daqin's, I'm afraid the financial capacity is not able to make so many wires, the amount of brass consumed is too much, in addition, this wire is placed on the ground, if it is stolen and cut off by civil thieves, this highness will not become an ornament, and the telegraph will lose its due effect, this problem is too much!"

"If we don't solve these problems, no matter how good this telegram is, I can't hope that it will be successfully promoted in my Great Qin!"
