Become the city lord from today

Liu Feng called the people from the scientific research department. Rather than calling, it was better to say that it was time to report the scientific research results.

People from the Scientific Research Department sent several representatives to the highest building. These representatives were all a bit elderly.

Of course, they are also the rare wise men in the Han Dynasty. Although they are a bit older, they don't know much as those young people.

"How have you been resting recently? Look at the haggard look on your face. Liu Feng walked to the sofa in the living room and sat down.

He waved his right hand to the sofa chair next to him, indicating that everyone in the scientific research department could also sit down.

"Your Majesty, thank you for your concern. We just have some insights these days, so we stayed up late for a few days."A white-haired old man with a beard said respectfully.

"Your Majesty, we don't dare to sit on an equal footing with you. We can just stand and report to you."Another old man was a little flattered.

There were 6 old men in total who came to the highest building this time, and each of them had gray hair and full beards.

Even their beards were gray. It can be seen that they are really old. Older.

Of course, not all the people in the Scientific Research Department are elderly people, there are also some young people.

It’s just that the last time Liu Feng assigned them the task, it happened to be these old men in charge.

So this time Naturally, it is these participants who come back to report on the work. Only they can accurately state the scientific research results.

"It doesn't matter, you can sit down if I tell you to. You have been working hard for a while."Liu Feng still raised his hand and pressed it.

He still respects these old men. In addition to their contribution to the development of the Han Dynasty, the most important thing is their age.

It is true that he is the king of the Han Dynasty. But he will not forget the traditional virtue of respecting the elderly.

Liu Feng has always felt that the traditional virtue of respecting the elderly and loving the young cannot be lost, even if he has traveled to this different world.

Or maybe he has already sat on it The king of a country, but the blood flowing in his bones has never changed, not to mention that these old men also respect him very much.

"Thank you, Your Majesty."Several old men said in unison

"You still need to take some time to rest, there is no particular rush for this."Liu Feng said.

The expressions of the old men were obviously changed a lot, and they were even more haggard than last time.

It was obvious that they had been spending time on this research, and they were told to take care of themselves because there were still many things to come. Let them do the research

"Thank you for Your Majesty's concern. We will definitely take care of ourselves and work for His Majesty."Several old men said again

"How is your research on home phones going? Liu Feng asked.

The last task he assigned to the Scientific Research Department was this task. Because of the invention of radio, the first thing that came to his mind was the home phone.

If home phones could be developed, it would be very important to the development of the Han Dynasty. It is a great contribution.

Of course, this is not an easy task. We have been researching it since last year, and today is the time to accept the research results. Today I am just asking about the progress of the research. It must not be out so soon. As a result, I happened to be able to answer the other party's questions.

Otherwise, with the character of the scientific research department, I would have happily sent the results to the highest building.

"Your Majesty, we don’t have any clues yet. There are many things we can’t solve."An old man shook his head.

Researching home phones is not a simple matter. It is more difficult to take into account the propagation of sound to another direction.

The birth of home phones on the other side of the earth still took a long time. It has been a long, long time, how could it be so fast now?

Although Liu Feng has mastered a lot of knowledge about traveling from the other side of the earth, it will definitely take time to copy it.

"Yes, Your Majesty, we can only propagate sound a short distance now, but we can't hear it very clearly, but this is also a breakthrough."Another old man reported

"We used the same frequency as the telegraph, but found that the words that finally came out were still incomprehensible."Another old man shook his head helplessly.

They have been researching for more than half a year, but the results they often come up with after several months of research have failed. It just happened that there was something new a while ago, which means that sound can be transmitted over a short distance..

Everyone began to stay up day and night, trying to research the home phone before the reporting day.

"oh? Have you all been able to carry sound a short distance? That's a good start."Liu Feng nodded with satisfaction.

This may not be particularly good news for those old men, but it is very good news for him.

Being able to spread over a short distance is already a very big breakthrough. Yes, but this is most likely based on the previous telegraph machine.

"Your Majesty, you said that sound travels faster than light. What do you mean?"An old man was confused.

Liu Feng had told them about the junior high school geography knowledge on the other side of the earth before, but people in this era didn't understand these aspects.

They were also stunned when they listened. , even after thinking about it for a long time, I still couldn’t figure out why.

"This is a physics book. Everything I told you before is included in it, and it will also be helpful for you to make a phone."Liu Feng handed over a book from the table.

This book was a physics book that he had translated for more than half a year. The content included junior high school, high school, and college physics.

Originally, he wanted to make it a little more complicated, but it was in line with this era. It is a bit difficult for people to understand overly complex physics.

In addition, this physics book is urgently needed, so he only translated the physics for junior high school, high school, and college.

The content in this physics book can be The details are as follows: sound propagates faster than light, sounds are emitted by vibration, and there are also positive and negative electricity. In short, the content inside will definitely make the people in the scientific research department ecstatic, and also have a strong interest in the research of the scientific research department. It is helpful.

In addition to busy processing documents, Liu Feng has been translating this physics book recently.

Because relying solely on the knowledge reserves of people in this era is definitely not enough, and he must pass on the knowledge he knows to them.

"Your Majesty, can this book really be given to us?"The old man who took the lead was extremely excited.

He picked up the book with trembling hands and flipped through it. He felt that this book was the source of all His Majesty's knowledge.

This is why they were really flattered and felt that it was so good. How can I give them the book?
