Liaoning.

Li Yan's palace.

Xu Guanzhong and Liu Qi came to see Li Yan together.

At this time, Li Yanzheng and a group of scientific researchers were experimenting with the world's first generator and the first electric light.

This generator was developed by a scientific researcher named Su Dahao - on the basis of the theory provided by Li Yan.

Because he doesn't know much about the structure and principle of the generator, the theoretical basis given by Li Yan is very vague, and it can even be said that Li Yan said three terms - magnet, copper wire, and generator.

Of course, Li Yan also gave a theoretical basis, that is, electromagnetic induction - magnetism can generate electricity, and electricity can also generate magnetism.

But these three terms, plus the four words "electromagnetic induction", in history, are the conclusions reached by countless people after countless careful observations, countless people after decades of research, and countless luck of countless people.

It can be said that after getting these three terms and these four words, the scientific researchers in Dazhong have taken a shortcut that has been countless times closer.

and then after Li Yan's unsparing promotion.

After nearly a decade of research and development, the world's first generator has finally been developed.

As for this electric lamp, strictly speaking, it can't be said to be an electric lamp, it is an arc lamp made of two carbon rods - this arc lamp, the brightness is too strong, the heat is too much, and it is not durable, in fact, it has no use value at all.

But—

This can already give researchers enough confidence.

Li Yan believes that it will not be long before they can develop a practical electric light.

Although in Li Yan's view, there is still a long way to go.

But Xu Guanzhong and Liu Qi, who happened to see the dazzling light of the arc lamp, were full of horror - they had never experienced this kind of visual impact, and they were completely shocked by the sudden bright light!

After observing the generator and arc lamp that were so simple that they couldn't be simpler for a while, Li Yan's face also showed a smile, and then said, "Intention." ”

The messenger listened to the words and hurriedly stepped forward to record.

Li Yan said: "Su Dahao has developed the world's first generator, which has made great contributions to Sheji, and has made great contributions to all mankind, and has a special reward for a mansion in the inner city of Yanjing, with a thousand taels of gold and ten thousand taels of silver, and he has been promoted to a baron, and his mother and son are well-governed, and he is named the wife of the seventh grade, and his immediate family members are exempt from tax for 30 years......"

After a series of heavy rewards, a young man of twenty-five or sixteen years old was so excited that he fell to his knees at once, and then said loudly: "Thank you, Your Majesty, for the heavy reward!" ”

It's no wonder that Su Dahao is so excited, he turned out to be just a very ordinary civilian, just because he has been very fond of tinkering with some messy things since he was a child, and he was lucky to be specially recruited into the Chinese Academy of Sciences and ate the imperial grain.

Everyone said that Su Dahao had caught up with a good era, otherwise, he would never have been able to eat the emperor's grain, and he could only plant the land for a lifetime.

Su Dahao cherishes the opportunity to eat imperial grain, so after entering the Chinese Academy of Sciences, Su Dahao has been constantly learning and engaging in research and development.

Because of his excellent performance, Su Da had the opportunity to listen to Li Yan's lecture once.

Coincidentally, in that class, Li Yan talked about electricity, that is, electromagnetic induction.

Electricity and electromagnetic induction opened a temporary window for Su Dahao.

Since then, Su Dahao has devoted himself to the study of electricity.

Finally, all the research results of the Academy of Sciences were successfully developed by Su Dahao The world's first generator was successfully developed, and then Li Yan rewarded him.

Since then, Su Dahao can be said to have risen steadily, completely bid farewell to commoners, and became one of the nobles in the middle of the world.

It can be said that Su Dahao will be able to marry Bai Fumei immediately, and then go to the peak of his life.

How can Su Dahao, who has no background and no ancestral shade, not be excited?

Li Yan said to Su Dahao with a pleasant face: "This is what you deserve, the generator you developed has made human civilization take a big step forward, and it deserves to be rewarded." ”

Su Dahao was quite smart, and immediately said, "Little ...... Weichen was able to develop a generator, thanks to the theory of electricity and electromagnetic induction put forward by His Majesty, in addition, there is also a series of achievements developed by researchers from the Chinese Academy of Sciences...... Wechen is willing to ask His Majesty to deduct some of Wechen's rewards and give some to Bai Zongchen and them. ”

Li Yan nodded appreciatively at Su Dahao, and said, "You are very good, you have not forgotten your roots, don't worry, when Tang Long draws up a list of meritorious people, I will reward you separately." ”

Then, Li Yan said to the hundreds of scientific researchers around him: "As long as you can develop something useful, I will definitely not be stingy with rewards!" ”

When a group of scientific researchers heard this, they said in unison: "Thank you, Your Majesty! ”

At this time, the arc lamp also went out because it could not withstand the huge heat.

When several researchers saw this, they wanted to change two more carbon rods.

Li Yan stretched out his hand to stop them, and said: "No need, this carbon rod is not a good material for making electric lights, you can develop new materials, by the way, there is an ore called 'heavy stone', you can try to refine it, maybe you can develop a stable filament." ”

"Heavy stone" is actually tungsten ore.

Obviously, Li Yan has provided a shortcut for scientific researchers in colleges and universities.

Smart people, hurry up and firmly engrave the word "heavy stone" in their hearts, maybe they can become the next Su Dahao, take a step back, even if they can't rise to the top like Su Dahao, they can also be like those who drank soup in the process of generator research and development in the process of electric light development.

After chatting with a group of scientific researchers for a while, Li Yan let them go down.

After all the scientific researchers left, Xu Guanzhong and Liu Qi stepped forward, and then Xu Guanzhong said: "Official, we want to send Yue Fei and the Left Route Army to Ningbei City to set up defenses, so that in the future, the Jin and the Mongolian people will flee to the central and western regions of the Mongolian Plateau, or even to the Western Regions." ”

Li Yan said very casually: "I have already told you, although I said to the outside world that this is a personal expedition, but in fact, I have already handed over the two of you, I am afraid that you will not pay attention to this Northern Expedition and are afraid that others will hinder your Northern Expedition, so I put up the name of a pro-expedition, I still say the same thing, how the battle is fought, I don't care, it is all up to you to say, as long as I see the result, as long as I see you destroy Dajin and the Mongolian tribes, if anyone dares to hinder you from fighting this battle, or if any side does not actively cooperate with you, You can come to me, I will definitely solve it for you, and you should not bother me anymore about other things, I can finally take a rest, and you must be considerate of me. ”

Xu Guanzhong and Liu Qi looked at each other and smiled bitterly: "Who said that the official family is so happy, the person who said this doesn't understand how vast the official family's mind is." ”

Then, Xu Guanzhong and Liu Qi glanced at the generator and arc lamp that the inner servant was moving, and said in their hearts: "They don't know that the official family doesn't need to wage war against the outside world to increase their merits, and if the official family wants merit, there are all ways." ”

Of course, although Li Yan has already said that they can decide everything for themselves, but as a courtier, Li Yan did hang the name of the imperial driver, and Xu Guanzhong and Liu Qi still had to tell Li Yan about important things, such as the transfer of Yue Fei and 200,000 troops to Ningbei to seal the way for the Jin and Mongols to flee west.

But then again, Xu Guanzhong and Liu Qi did this, in fact, it was really redundant.

Li Yan's personal expedition this time was really just like what he said to Xu Guanzhong and Liu Qi, he was afraid that Xu Guanzhong and Liu Qi would not be able to completely solve the two major troubles of the Jurchens and the Mongols.

In addition, in addition to this most important reason, there is actually a small reason, that is, Li Yan wants to see if his son Li Cun can manage the huge empire of Dazhong?

PS: Kavin, so I couldn't write two chapters, and today there is only this one chapter, I'm really sorry!

In addition, let me tell you again, this book will end this month, that is to say, this book has reached the final closing stage, therefore, the update is not very good to guarantee, after all, there are too many holes to fill, the further it goes, the bigger it gets, and there are more and more things involved, which is really not as easy to control as before, so I can only try to keep changing, I hope you can understand.
