A few days later, it was nearly evening, and the ministers of the cabinet were ready to disperse.

But at this time, an attendant appeared and sent a message to them, and the emperor summoned them in the Wenhua Palace.

Xue Guoguan and the others were a little puzzled when they heard this, thinking in their hearts, could there be something urgent?

Now that the four seas have been pacified, the matter of rebellion should be impossible. The emperor's reputation for invincibility is the best deterrent.

Then, it is only possible that there is a serious disaster: most likely, it is the earth dragon that rolls over, or a hurricane strikes.

This kind of disaster will come very suddenly, and it is impossible to prevent it. Moreover, it is likely to be very serious, so it is possible that the Cabinet has not yet known about the disaster, and the disaster has already been rushed to the Imperial Palace.

Thinking like this, they didn't dare to slack off, and hurried over.

Just when they were on the square at the entrance of the Wenhua Palace, Xue Guoguan and the others suddenly found that the six Shangshu were also coming in a hurry, and they couldn't help but be very shocked, could it really be that a very serious disaster had happened?

"Do you know where the Earth Dragon turned over?"

"The earth dragon turned over, haven't you heard? If there is, it should be the most likely in Sichuan! ”

"Or is it a hurricane coming, can there be Fujian, Zhejiang, Guangdong, or the report from Annan?"

"The Cabinet doesn't know, how can we know?"

“……”

After asking each other a little, they couldn't find the result, and when they arrived at the gate of the Wenhua Palace, all the civil officials had serious faces, sorted out their appearances, and then talked about it.

The emperor was already in the Wenhua Palace, and after the roll call entered, to Xue Guoguan and the others, to the surprise of Xue Guoguan and others, the people of the ceremonial supervisor were already there, and even the crown prince and Song Yingxing of the Kaiwu Division were also there. And they all looked a little excited, which made them even more surprised, this is not like a serious disaster has happened!

Immediately afterwards they saw in the middle of the temple there was something they had never seen before, and on top of the pole there was a glass jar that seemed to have something in it.

As soon as they saw this, Xue Guoguan and the others suddenly came back to their senses, the emperor had said a few days ago that there was something to open their eyes, should this be the one in front of them?

When they saw Emperor Chongzhen's smiling face, they confirmed this even more.

So, they breathed a sigh of relief in their hearts, and at the same time, their curiosity came up.

After seeing the ceremony, Xue Guoguan said on behalf of the crowd: "Your Majesty, what is this? ”

The other courtiers looked at this strange thing, and they were also curious, so they pricked up their ears and listened, seeing what new things the emperor was going to show?

At least one thing they know, what the emperor showed them is of great use.

For example, the steam engine has been used in many places nowadays, steam trains, steam ships, and other steam forging presses are all things that have had earth-shaking changes in the Ming Dynasty.

So what will this one be used for? Anyway, looking at it, there is no place to get close to the steam engine!

Emperor Chongzhen glanced at the faces of these courtiers below, smiled slightly, and looked outside a little.

At this time, the sky was already dark, and if it weren't for the bright light of the fire candles in the Wenhua Palace, it was estimated that it would be difficult to see things a few feet away.

So, he commanded in a relaxed and happy tone: "Song Qing start, prepare to blow out the candle!" ”

As soon as Emperor Chongzhen's words fell, Song Yingxing bowed down to receive the order, and immediately walked to the strange thing in the hall, and before he could squat down figuratively, he took a place with a handle and squatted down.

"Puff puff ......" Immediately after, the attendants who had been waiting by the candles vigorously blew out the candles they were responsible for. In the Wenhua Palace, it suddenly darkened.

Xue Guoguan and the others, from the bright environment to the darkness, suddenly had a feeling that the world had become dark all of a sudden.

But before they could get used to the environment, they saw a bright light appear in front of them.

Even if it was just a glimmer of light at the beginning, it was very conspicuous in this darkness. What's more, this glimmer of light is slowly getting brighter and brighter. Later, at least it will be able to illuminate the hall.

It wasn't until this time that Xue Guoguan and the others saw clearly that Song Yingxing was squatting there shaking something, and then there was a bright light from the glass bottle that he had seen before. In the dark night, like a bright lamp, it is much brighter than ordinary fire candles.

didn't say it, the thing that the emperor said before to open his eyes is definitely this shining thing in front of him.

This thing is definitely not a night pearl, let alone a candle or something like that. But this thing just shines. However, it seems that the light is not consistent, and it will change slightly from time to time.

What the hell is this thing? Could it be that it has something to do with the knowledge taught by the emperor?

Thinking of this, these courtiers immediately recalled, wanting to know what knowledge this had to do with the emperor's teaching?

"Your Majesty, what is this?" Xue Guoguan asked directly, saving effort.

However, after Emperor Chongzhen heard this, he did not answer, but instructed the crown prince Zhu Cihong: "Go and show it again." ”

"Sons obey orders!" Zhu Cihong hurriedly agreed, and then walked over with something and put it on the glass bottle, and suddenly, Xue Guoguan and the others saw a bright light, which turned with the turn of the prince's wrist.

As long as the light is reached, it can be seen clearly, at least within the confines of this hall, no matter which corner.

"That's it!" After a while, Emperor Chongzhen suddenly spoke.

So the chamberlain re-lit the candle, and the hall suddenly became very bright again, not only where the beam of light struck.

Song Yingxing, who was squatting on the ground, stopped shaking that thing, stood up and saluted the emperor. With this thing of his, the light on the glass bottle slowly dimmed.

Zhu Cihong also put down a hood with a bell mouth, put it on the ground, and saluted Emperor Chongzhen, indicating that he had completed his obedience.

Only then did Emperor Chongzhen smile and say, "This thing, I call it an electric lamp." It does not emit light by burning candles and the like, but is related to the physical electromagnetic induction and cutting of the magnetic circle. I'll let the prince tell you about it for me! ”

Xue Guoguan and the others listened, and it was really an eye-opener, and it was related to the knowledge taught by the emperor!

When Zhu Cihong heard this, he was very happy, and immediately explained it to Xue Guoguan and others.

Emperor Chongzhen was also listening, smiling.

Electric light can surpass the steam engine. However, for the current Ming Dynasty, the practicality is far inferior to the steam engine, therefore, the electricity is put behind by Emperor Chongzhen, at least from the current point of view, the development of the steam engine has been relatively mature, and he came up with this thing.

However, it is not so easy to make this device, at least in the current period, it is impossible to mass produce and apply it on a large scale. Copper wires, enameled wires, tungsten wires, vacuum in light bulbs, permanent magnets, bearings, etc., cannot be produced on a large scale.

This also determines that at least for a long time in the future, before the advent of pre-technology, it is impossible to mass production, and it can only be destined to be the application of luxury goods. However, one thing is possible, when the headlights on the train, and even the lighting of the carriages is possible.

As for why this electric light experiment was made, it was still what Emperor Chongzhen said to them at the beginning, which opened their eyes. It is not only to open the eyes of the high-ranking officials of the Ming Dynasty, but also to the eyes of the Ming scholars and the people.

Once the luxury of electric light is used in the royal family, then the upper class of the Ming Dynasty such as princes and nobles, civil officials and military generals will rush to it and strive to have it. In short, it will become the new fashion of Daming.

In this way, there will be more people to study electromagnetic induction, to study the application of electricity, and so on. It's no longer just by relying on the Kaiwu Division, the War Bureau and other official yamen of the Ming Dynasty to do this.

In addition, more facts have proved that the knowledge imparted by Emperor Chongzhen has so many magical applications, which will also make more scholars learn more attentively.

In short, the electric lamp, just like its name, will point out a scientific direction to the people of the Ming Dynasty.

Of course, the development of electricity in the original history is different, and the knowledge of Emperor Chongzhen is used as a precursor, so that the people of the Ming Dynasty can take a lot of detours, so that the science and technology of the Ming Dynasty will develop faster than the development of the original history.

Just like these, in terms of chemistry, Emperor Chongzhen has actually been letting them study, three acids and two alkalis, etc., are also experimenting. As a person who traveled through the later generations, of course, he could not be satisfied with black powder to fight the world, although he could indeed fight.

However, Emperor Chongzhen is not omniscient and omnipotent after all, in terms of chemistry, he really doesn't remember much, he can only do his best, as long as he guides the direction and gives heavy rewards.

After a long time, Zhu Cihong gave a general introduction to the principle of electric lighting, as well as the current preparation and future application.

Needless to say, Xue Guoguan and the others were amazed. After a while, Xue Guoguan said with emotion: "Your Majesty, if only this electric light could be stable and bright." ”

When Emperor Chongzhen heard this, he smiled and said, "This is the reason why Song Qing's hand is not evenly shaken. It would be better if you didn't use manpower, such as water power. Of course, the best thing is to have an energy storage device, a voltage regulator or something. But these things don't exist yet, and someone needs to research and build them. ”

Xue Guoguan and the others didn't understand what they understood, but they knew one thing that this thing could be improved to what they wanted. And so they couldn't help but look forward to it. It is really better than the light of a candle.

I don't know what's going on, after this day, there were rumors in the Jingshi, all saying that something strange happened in the palace.
