The principle of the generator is not difficult to understand, the simplest hand-cranked DC generator, the principle is to change the magnetic flux by rotating the permanent magnet to generate an induced electromotive force in the coil, and the electromotive force is output in the form of DC voltage.

This is a very simple middle school physics, although Yang Hao was a little unlearned when he was in school, but this theoretical knowledge was not returned to the teacher.

Of course, the hand-cranked generator could not meet Yang Hao's needs at all.

He doesn't want anything high-tech, he just wants communication.

And the easiest way to use electricity is telegraph.

Yang Hao's impression of the telegram is to express the conveyed information by the length of time that the key is in contact, so one key can solve the problem.

Perhaps influenced by the drama of the Anti-Japanese War, his impression of the telegraph is like this,

In principle, the telegraph press the electric key according to certain regulations, send out long and short signals, and then send out the message. The other party also knows what the word is according to its length and sound.

Although the principle is not difficult to understand, it is not easy to implement.

This is a more time-consuming and laborious project than building a dam.

But Yang Hao decided that no matter how difficult the project was, it would take more than ten years to realize it.

As long as the telegram appears, his empire will be impregnable, unless there are inviolable factors of manpower, or if there is a faint monarch, the state of Qi will have to last for hundreds of years.

Yang Hao didn't sleep that night, racking his brains to write tens of thousands of words of drafts with the knowledge in his mind.

The draft is messy and involves a lot of theoretical knowledge.

Until dawn, when the rooster crow in Chang'an City sounded, Yang Hao had already fallen asleep on the desk.

The sun rises in the early morning.

The palace ladies yawned and began their busy day.

Although the Great Qi Palace does not have many rules like the later dynasties, these palace maids do not dare to slack off in the slightest.

If you make a mistake and are kicked out of the palace, it is estimated that you will only be lonely for the rest of your life.

"King! It's time to go on the pilgrimage. ”

There was no response in the room, but snoring could be faintly heard.

Seeing this, the palace maids were a little embarrassed.

"The king didn't sleep last night, do you want to wait any longer?"

"I'm afraid this is not good, but the king has explained, no matter what the situation, you can't delay the early dynasty."

"But Sister Red Kite, it's too terrible for the king to come over, I don't dare to call the king!"

"Don't talk nonsense, hurry up, you see that it's not early at this time, it will affect the king's rest, you and I will scold at most, if you delay the business, even the lady concubine will not be able to protect you and me."

The little palace maid could only bite the bullet and knocked on the door again.

"King! It's time to go on the pilgrimage. ”

"Be louder! I didn't even hear how the king could hear it. ”

The little palace maid took a deep breath, exerted all her strength, knocked on the door dangdang, her emotions were not controlled for a while, and she shouted loudly: "King! It's time to go on the pilgrimage. ”

This sound was extremely penetrating, and it immediately frightened the other palace maid to the point that she almost knelt on the ground.

pinched the little palace maid fiercely and scolded: "You want to find death!" ”

In the study, Yang Hao was also frightened by this voice, and almost fell off the table.

Being disturbed by someone disturbed his good dreams, coupled with the anger that everyone had to get up, Yang Hao roared angrily: "What are you shouting, believe it or not, Lao Tzu cut you." ”

When the two palace maids outside the door heard this, they were suddenly frightened and their legs weakened, and they knelt on the ground all of a sudden, and said: "The slave is guilty, the king spares his life, and the king spares his life." ”

Yang Hao, who was originally very angry, saw that it was already bright outside the window, and heard the sound of begging for mercy outside the door, he knew what was going on after a little thought.

After tidying up his clothes, he walked out of the study and saw two young girls kneeling at the bottom of the steps.

When the second daughter saw Yang Hao come out, she was even more frightened and trembled, thinking that she would be ordered to be executed by Yang Hao immediately, and in fear, the two even forgot to beg for mercy, but kept kowtowing.

Even the slightly older palace maid already had blood stains on her forehead, which showed how much fear Yang Hao's words brought to the two of them.

Yang Hao glanced at the two of them and said, "You guys are doing well, get up!" ”

When the two of them heard this, they could hardly believe their ears, and knelt there in a daze.

Yang Hao said in a deep voice: "What are you doing there?" Yet to fetch water for the king to wash. ”

As soon as the second daughter heard this, she knew that her little life had been saved today.

"Yes! Slave maid, this is for the king! ”

Speaking of the second daughter, it seems that she is busy for Yang Hao as if she is running.

Yang Hao, who yawned repeatedly, finished wearing the cumbersome crown dress under the service of the second daughter.

Before proceeding, Yang Hao said coldly √ second daughter: "Today's incident is not an example, if it happens again, it will be implemented according to the rules of the palace." ”

After speaking, Yang Hao got into the carriage and walked in the direction of the court.

In the court, the civil and military forces of the Manchu Dynasty have already arrived.

The bigwigs sat in their respective positions, looking at the empty throne and looking at each other,

As a fairly diligent emperor, Yang Hao has reigned for more than ten years, and there are few times when he is late, and Yang Hao's absence has made many people a little uneasy.

But soon these people's worries disappeared with the arrival of the king.

Yang Hao, whose eyes were bloodshot, sat in his position with a little sluggishness, and looked at the Manchu Dynasty civil and military forces casually.

"Something to start and quit the dynasty without anything!"

"King Qiqi! There is a play! ”

Yang Hao was depressed, and the man glanced at it and said, "What does Zuo Xiang have to play?" ”

Shao Yan said: "King Qiqi, now that the army to conquer Tushan has been prepared, the minister thinks that when the army is ready, he should be ready to take over the newly opened territory.

The minister suggested that the land of the Tushan tribe should be included in Jingzhou, Jingzhou is the place where I have been developed by Daqi for many years, and with the power of Jingzhou, the minister thinks that at most two years, this place can become no different from my Daqi. ”

Yang Hao nodded and said, "What the left minister said, you ministers can have objections. ”

Seeing that no one stood up to object, Yang Hao said: "So according to the words of the left minister." ”

At this time, Kong Rong, the new secretary of the military department, got up and said, "King! Yesterday, the Ministry of War received a report from Qinzhou, and it was found that the remnants of the former Xia appeared in the north of Qinzhou not long ago, and it seemed that they had been in the same place with the northern barbarians, and there were signs of growth. ”

Yang Hao snorted coldly when he heard this.

"A group of lost dogs can't set off the wind and waves, and the defenders everywhere must not be slack!"

Kong Rong nodded and said, "In addition to this matter, the minister should have something to play!" ”

As he spoke, Kong Rong took out a chapter of paper full of strange symbols from his sleeve.

"Look, King!"

When Yang Hao took the paper from the guard's hand and unfolded it, Yang Hao suddenly changed color.

"Impossible, absolutely impossible," muttered. ”
