Become a feudal king from today

"Yes, everything related to electricity. Read М" Zhao Xu smiled, "Do you still remember the voltaic battery and wired telegraph I talked about?"

"Of course I remember." Wang Chong scratched his head and suddenly felt a little embarrassed, "To be honest, I secretly made a joke."

Hearing this, Zhao Xu burst into laughter, "So, today I can see a ready-made one? Go get the voltaic battery and build a laboratory wired telegraph for me in the next two days."

There is still a gap between the things in the laboratory and the actual things. It can be said to be a simplified version.

Because from the laboratory to the popularization of something, many details need to be perfected.

"Yes, the voltaic battery is in Chen's room." Wang Chong raised his eyebrows and called a student to pick it up.

He has been living here since the R\u0026D institute was built.

There are dedicated people to take care of food, clothing, housing and transportation, and they only need to concentrate on research and development.

After a while, the student came over with a cylindrical metal object.

It is the voltaic battery.

This cylindrical metal is not actually a whole body, but is like a candied haws, with a copper stick in the middle, and then stacked together in order, round copper sheets with holes in the middle, paper soaked in salt water, and zinc sheets.

Separately, these three are nothing, but stacked together they become a battery.

Tie copper wire to both ends of the middle copper rod and it can be used for wired telegraphy.

Therefore, in the 19th century, there was often a large box next to the telegraph machine, with voltaic batteries placed in the open spaces.

Seeing the voltaic battery with his own eyes, Zhao Xu nodded slightly, "Don't forget the wired telegram. This does not require my personal participation, right?"

"I have learned so many things from His Highness, and if I don't even know how to do this, wouldn't it be like being a loser?" Wang Chong looked confident.

In the study of electricity, voltaic batteries and wired telegraphs are the most basic things. They are easier than steam engines, but they become more difficult as you go later.

He only needed copper and iron wire and a few copper plates to make a wired telegraph in two or three days.

"Even so, I will give you three days. After three days, I will see the laboratory cable message." Zhao Xu set a deadline for Wang Chong.

He was confident in Wang Chong. With the current industrial foundation, he could easily use lathes to manufacture spare parts for wired telegraphs.

However, some telegraphs are easy, but the really difficult problem is the transmission of messages through wired telegraphs and the laying of wired cables.

The original wire telegraph transmitted messages via Morse code.

He also had to come up with a set of such codes and compare the long and short frequencies with the corresponding text to accurately convey the message.

Solving this problem involves laying cables.

A wire telegraph that could not carry messages throughout the Great Song was useless.

This cable is a combination of copper wire and iron wire.

It is necessary to use oil paper to wrap the copper wire and iron wire separately to prevent contact short circuit, and then wrap a layer of cotton gauze soaked in linseed oil around them.

Although the process is not difficult, at least thousands of kilometers of cables are needed to cover Jiangbei with wired cables, which is no small project.

Therefore, he said that wired telegraphy in the laboratory is easy, but it is not easy to popularize it.

But just like laying railways, there are also difficulties in promoting the development of Dasong.

He didn't want to have one day when his army was fighting overseas and the other party sent a wired telegram to the battlefield to provide on-site command and dispatch.

And his generals had to send people back by boat to ask for instructions.

After instructing Wang Chong on this matter, Zhao Xu left the research and manufacturing institute.

After the wired telegraph was developed, Wang Chong could conduct various electrical experiments until one day he could build a thermal power plant and output electricity through transformers, ushering in the second industrial revolution.

When he came to the street, Zhao Xu did not go back to the palace immediately, but went to the Science and Technology School.

After Wang Chong's group of students graduated, the Science and Technology School did not stagnate. Instead, it continued to recruit new students and even expanded the number of students.

Walking in the school, except for a few old students who stayed to teach in the science and technology school, all of them were new faces.

Many people were studying hard in the corridor of the school with textbooks in hand.

Satisfied with the current situation of the Science and Technology School, he went to the Military School, Government Affairs School, Naval Academy, etc.

The same goes for these schools. They are all in good order and have established a complete school management system.

Dasong’s talent training system has initially matured.

He doesn't need to worry as plenty of talent continues to emerge every year.

In the future, with their efforts, Dasong will only develop faster and faster.

After inspecting the school, Zhao Xu finally went to the Military Division.

The war in Goryeo is over, but the dark clouds of war still echo over Dasong.

The Eastern Territory Alliance is still determined to destroy Da Song, and it will definitely not stop after Goryeo.

On the military front, he could not relax.

After all, this is an era of great changes in weapons.

Western technology is also constantly advancing. In a few years, breech-loading guns, breech-loading cannons, and iron-clad ships will all appear one after another.

"How are the rifled cannons?" When they arrived at the Military Division, Zhao Xu asked directly.

He has been in Goryeo for so long, I believe Wang Ying must have some insights.

This time, he wanted to replace some of the sail battleship's guns before the steam engine was launched.

In order to completely destroy the British fleet in the East in the next naval battle.
