"I roughly understand what you mean!"

The empress nodded slowly: "Although I can't imagine what the vehicle you are talking about is, and I can't imagine what the city that never sleeps looks like, but...... I can feel it, what you say is true!"

"A vehicle that travels thousands of miles a day is naturally good, but other people must not understand it, right?"

"If you are the only one who wants to get this kind of vehicle out, the time it will take will definitely not be short!"

"Your Majesty is right. ”

Lin Zifan nodded: "That kind of vehicle, it's called a car...... There are special vehicles for carrying people, as well as cars for carrying goods and transport, as well as trains that can carry a large number of soldiers and military supplies. ”

"But either way, in a short period of time, it's hard to time, I'm afraid...... It will take at least a year or so to see results. ”

In this regard, Lin Zifan was also a little helpless.

Before that, he was just a chef, he studied physics, chemistry and biology, and knew how to make a steam train, but the problem is that knowing how to make it is very different from doing it himself!

Not to mention cars, trucks and whatever, those things have exceeded the scope of his current knowledge, even with the help of the system, tens of thousands of parts for a car cannot be done in a very short time......

"That's it, it will take too long, but I'm afraid the Tang Dynasty will ......" The empress frowned slightly, and then asked: "How the City that Never Sleeps is done, I don't know, but I want to know if it can improve some combat effectiveness while creating the City that never sleeps?"

Lin Zifan was stunned for a moment: "Is it combative? Your Majesty wants to ......"

The empress nodded: "On the side of the Qin State, the movement is unknown, but I am always a little worried...... If you can increase your combat power, it would be great!"

"That's true!" Lin Zifan groaned slightly......

The city that never sleeps?

Well, the bulb can be ruled out, but if it is said to enhance the combat effectiveness, electricity seems to be ......

"In a way, yes!"

Lin Zifan opened his mouth, but only said that it could improve his combat effectiveness to a certain extent: "But if you want to use it for war, it is too difficult." ”

"This ......"

The empress also had some difficulty making a decision for a while. But she still said, "I suggest that you finish what you said about the city that never sleeps. ”

"Because...... I'd love to see what the city that never sleeps looks like!"

"It's a bit selfish. The Empress shook her head and chuckled.

"Where?" Lin Zifan was happy: "Your Majesty wants to see it, even if it is the moon on the horizon, the minister can take Your Majesty to see it, let alone the city that never sleeps?"

"Really?" the empress suddenly became interested and looked at him with a smile.

Lin Zifan: "......"

[Poof, don't you really want to slap yourself?

"You can ...... it"

After finishing the system, Lin Zifan really wanted to slap himself......

Go to the moon to see? Even before the crossing, Huaxia couldn't send people to the moon to see it, right?

With his level of knowledge, unless the system suddenly turns over and becomes a hanger, he wants to go to the moon and see it? The devil knows how many years it will take......

Whether you can live that long is a question!

"Ahem, Your Majesty, there will be a day!"

The pace of progress will not stop, although it is a little embarrassing, but Lin Zifan still said that as long as he can live for so long, then everything is fine.

"So...... The first goal at the current stage is set, and the first ...... Make wires, light bulbs, and generate electricity!"

"If you want to generate electricity, it is perfect to build a hydropower station directly in the upper reaches of the Ganges, but the difficulty lies in the ...... generators."

"In terms of wires and switches, rubber is already available and can be used as plastic, but copper wire is a problem. ”

"The light bulb was not easy, first we had to find the metal of tungsten, and then the glass ......"

Under such rudimentary conditions, to make a light bulb, it is natural to make an old version of the electric lamp, that is, the kind with a tungsten filament in the middle.

As for the LED lights or something, that thing uses some kind of semiconductor material, Lin Zifan himself doesn't understand it, and he's still a fart?

The nitrogen filled in the bulb was originally a difficult point, but in a high-martial country like Datang, it was not a big problem.

After all, there is a lot of nitrogen in the air, but it is colorless and odorless, and it cannot be seen or touched.

But as long as the temperature is lowered to about minus 200 degrees, then the nitrogen will condense into a colorless liquid or even a solid!

And with the strength of a water attribute master like the national teacher, it is really not too difficult to make the temperature in the vicinity reach minus 200 degrees, but the scope of influence is not large.

But that's enough, let the nitrogen condense into a liquid or even a solid, seal it and collect it, and then when the temperature rises, doesn't it turn into a gas again?

When the time comes, just fill the bulb with it.

"So...... The main question is actually copper and tungsten? These two metals, I don't know if Datang exists. ”

Lin Zifan suddenly had a little pain, he finally got the steel, and now he is looking for copper and tungsten?

As for generators...... In fact, the principle is not too difficult, when he was in high school, Lin Zifan even made a small hand-cranked generator by himself, but the quality or something...... He can't guarantee it.

"Difficult?"

At this moment, the empress was quite gentle and spoke slowly.

"It's a bit difficult, the supplies are too scarce, but it shouldn't be a big problem. Lin Zifan chuckled: "But Your Majesty, I'm afraid the minister will have to leave for a while." ”

"During this time, Your Majesty should not think too much about me. ”

When the empress heard this, she instantly rolled her eyes: "you, who will miss you?"

"But I'm somewhere else, I'm not around, you just have to be careful. ”

Don't miss you too much?

The empress naturally wouldn't admit this, but she still told Lin Zifan to pay attention to safety rather worriedly.

"Your Majesty rest assured, the minister understands! Moreover, the minister is also very afraid of death, and he will definitely run fast when he encounters danger!"

"It's strange to believe you!" the empress pouted......

"What's more, the minister will marry His Majesty soon, how can he never go back?" Lin Zifan smiled, and then, in the white eyes and shame of the empress, he 'fled' from Qifeng Pavilion.

......

"Copper wire and tungsten wire?

Back at the logistics mansion, Lin Zifan touched his chin, his eyes were gloomy, and there were thousands of thoughts in his mind.

If you just go out to find it, so many mountains and rivers in Datang will undoubtedly be looking for a needle in a haystack, and you will not be lucky for a few months.

However, I had an idea......

"After the salted fish system turned over, although it was still a salted fish, it could be regarded as a turnover after all. ”

"In that case......"

Lin Zifan's eyes froze.
