"The telephone is definitely a turning point for Daqin communication, and it must be a ...... for popularization and promotion!"

In the expectant eyes of Ying Zheng, Wang Ben and others, Ying Feiyu continued: "However, the most important point in popularizing the telephone is not the production of telephones, but telephone lines! ”

"Phone line?"

On the day of the phone test, everyone's attention was focused on whether the sound could come from the telephone, and they didn't notice any phone lines at all.

"I seem to see a wire, isn't that an ordinary wire?"

The careful Chun Yuyue seemed to think of something and asked.

"No, although telephone wires can also conduct electricity, there is a difference between the two!"

Ying Feiyu shook his head and said.

"What? Is the production of a telephone more difficult than a wire? ”

Ying Zheng on the side asked.

"It's not that it's difficult, but Daqin's current copper mines are limited, that is, to produce copper coins, but also to produce wires, plus some trains, car parts and components need to use copper, and some copper mines dug out every year are in short supply! Coupled with the telephone line, the consumption of copper ore is even higher, which is bound to affect the previous ones! ”

Today, the morning dynasty was absent-minded, and Ying Feiyu was also thinking about this issue.

Although he can still find a lot of copper mines using the system, he doesn't want to develop the country and consume all the resources, burying hidden dangers for future generations!

It can only be a mineral deposit that can be preserved, and try to keep it as much as possible, so that future generations can slowly develop it!

"The application of electricity is very extensive, it must be popularized, and it must not be stopped!"

Ying Zheng said firmly.

"The Emperor is right! But trains and cars are of great help to people's travel, and they must not stop! ”

Meng Yi pondered for a moment, and then opened his mouth with a straight face.

"Copper coins are my Great Qin currency, and the people have to use them every day, and they must not stop production!"

Speaking of money, Zhang Han was nervous, as if he was afraid that he would not make copper coins in the future.

Now large transactions must be made with silver tickets, yes.

But small transactions between people, such as buying vegetables, drinking tea, etc., are all copper coins!

"This can't be stopped, that's not less, is it possible that the phone can't be used when it's researched?"

Thinking of this, Ying Zheng's heart suddenly became bored.

"Huh? Wouldn't that be a waste of research? ”

"It's a shame that it took so much time and so much energy, but it didn't work for the result!"

"Alas......!"

The veterans also took it seriously, and their faces were full of loss.

"I don't care what method your kid uses, anyway, the phone must be popular! If it really doesn't work, it will be mined from overseas, refined into copper, and then shipped back! ”

In order to be able to use the phone, Ying Zheng was also ruthless.

"Father, in this way, the cost has increased significantly!"

Ying Feiyu raised her eyebrows and reminded with a wicked smile.

"If you increase, you will increase! I'm not out of money...... Daqin! ”

Ying Zheng was resolute and arrogantly said: "I don't have enough copper mines in Daqin, so I don't believe that there are so many overseas states, can they still be enough?" After being shipped back by ship, won't the problem of the telephone line be solved? ”

"Haha! At present, Daqin is indeed solved! But did the father think about what the descendants of the future generations should do? As the population grows, the population of all states will skyrocket in the future, and electricity and telephones will also be universalized at that time! Now that all the copper mines in the states are mined and used, what should we do in the future? ”

Ying Feiyu deliberately made it difficult.

"Uh...... This one......? ”

Sure enough, after Ying Zheng heard this, he suddenly made a difficulty.

Just now, I only thought about solving the current dilemma, but I forgot to think about future generations.

Fortunately, the kid reminded me, otherwise I would have made the wrong decision!

"Your Majesty, you are resourceful, there must be a way to solve this situation, right?"

Meng Yi's sharp eyes found that Ying Feiyu's expression was somewhat smug when he said this.

I guess I've figured out a solution!

"Haha......! I have an idea! ”

"You stinky boy, since you already have a way to solve it, why are you still talking all this nonsense to me......

Seeing him smile, Yingzheng was immediately unhappy, "Isn't your kid teasing?" Hurry up and say, what is the solution? ”

"Aluminum!"

Ying Zheng shouted and asked, and Ying Feiyu no longer sold Guanzi, and spit out a word directly.

"Aluminum?"

The old guys repeated it with a suspicious look on their faces.

"That's right! Copper coins and car parts need copper, and that can't be changed! But wires can replace copper with aluminum! ”

"So, aluminium is also an ore that conducts electricity?"

This is the first time I've heard of this mineral, which is very unfamiliar to the old guys.

"That's right! The conductivity of aluminum is also very good, and it can completely replace copper wire! ”

Ying Feiyu fixed his head.

"You stinky boy, if you already have a way, why do you throw out the problem and let us old guys worry about it?"

As soon as his words fell, he was immediately counted down by Yingzheng.

It wasn't until now that he realized that this kid was doing it on purpose!

"Hey, hey! It's not right for my father to say that! The copper wire problem is indeed very difficult, and Erchen has been troubled for a long time, and he didn't come up with a solution until just now! ”

Anyway, the scumbag is not a roundworm in her stomach, and it is impossible to know what he really thinks in his heart, let alone when he thought of replacing copper with aluminum.

"Humph! You stinky boy, you can always find all kinds of excuses, if it weren't for my ......! ”

Yingzheng is not stupid, at this time, can he still see the truth?

Tickle the roots of his hated teeth.

If it weren't for the fact that this kid has the power of ten thousand catties, he would have started repairing this kid a few years ago, and he could still be so rampant?

"How's my father?"

"If it weren't for me...... I......? If it weren't for the fact that I had already taken the Zen position, I would have brought someone to solve this matter! ”

In front of so many people, he definitely couldn't admit that he was hindered by his efforts, so he didn't dare to clean him up.

I can only change the conversation and make an excuse casually!

"There are a lot of talents in the DPRK and China, and the phone calls have been studied, can you still trap a small copper mine?"

Ying Zheng was very satisfied with the excuse he had made.

"It's just that my father has been idle recently, so it's better for my father to solve this matter! It is also good to put aside the aluminum ore first, and leave more mineral deposits for future generations! ”

Since the scumbag dad wants to pretend to be X, then Ying Feiyu can't stop him, he must be given a chance to pretend to be enough.

"No, no, no! I'm already in the Zen position, so I won't rob you kid of the credit, or you kid will arrange someone to deal with it......! ”

Ying Zheng waved his hand again and again, what other ways could he do besides increasing the mining of copper ore? "Whether it is copper ore or aluminum ore, it is the mineral deposit of Daqin, and it is better to use some less, or to mine evenly! Ha ha! ”
