Chapter 1601, Lao Liu, Lao Liu, I am Lao Zhu

Beijing, Imperial College of Technology.

Liu Jin came here with an extremely excited expression.

"The radio telegram has finally been researched!"

"It's been too long to wait for a moment!"

No wonder Liu Jin was extremely excited. Since the electromagnetic induction phenomenon was discovered, Liu Jin has been waiting for these scientists from the Ming Dynasty to study the radio and telegrams as soon as possible.

Because of the huge Ming Empire, it needed this technology so much.

The Ming Empire was too big, and exchanges between regions were too slow.

From Nanyun Province to the capital of Daming, even if it uses eight hundred miles to transmit information, it will take at least half a month to arrive. It takes one month to go back and forth.

If it is passed on to the farther Golden Continent, it will take longer.

In this short period of time, the problem is not very serious, but over time, it will easily lead to the division within the Ming Empire and breed separatist forces.

Therefore, it is particularly necessary to efficiently transmit information, and the most ideal is naturally wireless telegraph.

Its technological content is not high. With the development of electromagnetic technology, it is not difficult to develop wireless telegraphs, especially Liu Jin also knows some knowledge related to wireless telegraphs and constantly provides guidance.

Now we have finally developed wireless communication technology.

"Mr. Liu~"

Lai Ji, president of Imperial College, took relevant personnel from electromagnetic communication technology to wait respectfully for Liu Jin's arrival.

"No need to be polite, take me to see our radio telegram."

Liu Jin quickly waved his hand and said.

"Please do this here by Liu Gong~"

Lai Ji said respectfully that Liu Jin is now a cabinet master of the Ming Empire, and is also the founder of Imperial University of Technology, a self-servicer, and a funder of radio-related technologies.

Liu Jin invested in the establishment of electromagnetic laboratories in many colleges such as Imperial College, Daming Institute of Technology, and the School of Mechanical Engineering, so that many people can study electromagnetics so that they can research wireless communication technology as soon as possible.

"How did you do it?"

While walking towards the laboratory, Liu Jin also asked in detail.

"Return to Mr. Liu~"

"Our school's electromagnetic laboratory has found through repeated experiments and research that by constantly closing the circuit, under electromagnetic induction, the oscillation current will be generated in the circuit. The frequency of this oscillation current is very high, and it can reach millions or tens of millions of times per second."

"Under such circumstances, we continue to conduct research and confirm the existence of electromagnetic waves. This electromagnetic wave is simply invisible to our naked eyes. Its propagation speed is very fast and can almost be comparable to the speed of light."

"So we thought about whether we could use this electromagnetic wave to transmit information, so that we could achieve long-distance instant communication."

Speaking of this, Lai Ji was very proud and began to talk to Liu Jin about the principle of electromagnetic communication.

"Oh, there are electromagnetic waves~"

Liu Jin naturally seemed to understand but he knew everything. He knew everything, but he was still pretending not to understand.

"Of course, the biggest contribution of the reason why this long-distance communication technology was to be able to be developed is the current Prince."

"He is the first person in the field of electromagnetic research and the first person to discover the existence of electromagnetic waves."

Then, Lai Ji mentioned Zhu Houzhao.

When Liu Jin heard Zhu Houzhao, he couldn't help but raise his eyebrows slightly.

His great interest in this prince who is not doing his job now is to create people and study various mechanical and electromagnetic technologies. Unexpectedly, he can really make contributions and achievements in the field of electromagnetics.

"We have conducted short-distance communication tests in advance. This time we invite you here to test the long-distance communication situation."

"Your Highness the Prince is now in Huairou County, and we are in Xincheng, the south district of Beijing. The distance between the two sides is already very far. If you can still communicate effectively, this means that electromagnetic communication technology is indeed reliable."

"Then in the next step, we will conduct longer-distance testing and conduct in-depth research in related fields, and find out that there is indeed feasible and reliable electromagnetic communication technology."

Lai Ji introduced it in detail.

In fact, this technology has been developed and is currently in the testing stage. Relevant tests have been passed before. This time, the distance is further away for testing.

There is a hundred miles away from Huairou County to Xincheng Imperial College of Technology in the south of Beijing. If electromagnetic communication can be achieved at such a long distance, it also means that it can continue to zoom in to a longer distance for testing.

This also means that infinite electromagnetic communication technology has infinite value.

If electromagnetic communication technology is used to transmit information from Nanyun Province to the capital in a very short time, then the Ming Empire's control over the entire huge empire will be easier and simpler.

There is no longer the need to use the 800-mile rush to transmit information like before, which not only consumes a lot of manpower, material resources and resources, but more importantly, the speed is too slow and can no longer keep up with the development needs of the Ming Empire.

Soon, under the leadership of Lai Ji, Liu Jin came to the Electromagnetic Laboratory.

Before entering the laboratory, Liu Jin noticed the high-mounted telephone poles on the laboratory building. There were many densely wrapped copper coils at the top, which should be a device used to receive signals.

"Liu Gong, this is a device used to receive the other party's signals. After the other party emits electromagnetic waves, we can receive them through such a device, and then combine them into regular transmission information based on the frequency and other information of the electromagnetic waves, so that infinite communication can be achieved at a long distance."

When Lai Ji saw that Liu Jin had noticed the coils on the building, he quickly explained in detail.

“So that’s it~”

Liu Jin smiled and nodded.

I came to the laboratory and looked at their device carefully. It was very simple and not complicated at all.

"This is a power generation device. We have studied and found that cutting a magnetic field can generate electricity, and electricity can also generate magnetism. Then we have studied the generator. By stepping on a bicycle, a person can generate a continuous current by constantly rotating the device on it."

"This is the transmitter of electromagnetic signals. After the current passes here, electromagnetic waves can be continuously emitted into the air, and then there will be a similar electromagnetic wave receiver on the other end. When the electromagnetic waves propagate, electromagnetic waves can be received, and finally effective information is formed for transmission."

Lai Ji introduced it in detail that this device looks simple, but it is the most technologically-rich thing in this era.

It is also the result of many people studying it for many years.

"Then let's start~"

Liu Jin listened carefully, and combined with some information from later generations in his mind, although this device is simple, it is no different from telegrams in later generations.

“Yes~”

Lai Jilian nodded and immediately ordered.

Soon, a strong student began to constantly step on the power generation device. As the power generation device began to generate electricity, the electromagnetic transmitter began to continuously generate electromagnetics here.

Of course, this kind of electromagnetic is invisible at all.

After a little adjustment, a specialized student began to knock on a button regularly, which made Liu Jin suddenly think of the plots he had seen in later movies.

Didi, Didi, Didi's voice was very rhythmic. Everyone held their breath and looked quietly, while quietly waiting for Zhu Houzhao's response from Huairou County.

On the other hand, here is the electromagnetic laboratory of Zhu Houzhao, Huairou County.

Zhu Houzhao was also excitedly staying in the laboratory at this moment. According to the agreed time between the two parties, it was almost about to start now.

"Didi~Didi~"

Zhu Houzhao didn't wait too long, and a regular sound came from the receiver.

"Haha, here it's here~"

Zhu Houzhao immediately laughed happily.

"Huai Rou, Huairou, I am Imperial College~"

"Please answer when you receive it~Please reply when you receive it~"

Looking at the translated information, Zhu Houzhao couldn't help but pout. This is also official.

After thinking about it, he personally controlled the transmitter, and soon a set of information was transmitted.

Imperial College's laboratory here.

Liu Jin and others were waiting patiently, waiting for the information from Zhu Houzhao.

I didn't wait too long, and the receiver responded.

The people in the laboratory quickly translated the information.

"Old Liu, Lao Liu, I am Lao Zhu~"

When the translator translated the information, Liu Jin immediately knew that this must be Zhu Houzhao, and he could not be wrong, and only he could be so casual.

"Ask him how many sons he already has now~"

Liu Jin smiled and thought about it and said.

Soon, a set of information was quickly emitted through electromagnetic waves.

"How many sons?"

"Haha, it's indeed Lao Liu~"

When Zhu Houzhao received the message, she immediately laughed happily.

"Old Liu, I have given birth to forty-five sons, you have to work hard~"

“…”

Liu Jin was speechless immediately. This guy has now become a big breeding pig~
