The Ming Dynasty’s Prodigal Son

Hiding in Zhuangzi outside Tongzhou City is very boring, or Fang Jifan's heart is anxious!

In order to prevent being noticed, it is best not to go out for activities except for a few cronies, otherwise it is difficult to be discovered without the ability of the factory guard.

Therefore, Fang Jifan and Zhu Houzhao almost lost contact with the outside world, and did not know how Annan was fighting, let alone his majesty ’s current situation. Fang Jifan was even imagining, maybe his majesty wanted to kill only the prince. Fan may be innocent, but not necessarily.

If so, you can go back to Beijing in a fair and decent way, and you can see your lovely apprentices and grandchildren, and you can also eat Mr. Wen's meals. This is a very pleasant thing.

With this thought in mind, Fang Jifan was even more impatient, and his heart was like an arrow.

Zhu Houzhao's situation is similar. He was very excited about the first two days, but he could not stay here anytime soon, but he didn't dare to show his head and could not help but complain in front of Fang Jifan: "If there is any news in Jingli I can tell this palace for the first time how good it should be, and I do n’t know what is going on in Jingli. "

Fang Jifan heard Zhu Houzhao's words, a thought flashed in his mind, and a strange feeling came into his heart.

Afterwards, I was just about to move!

Our side Jifan, the two generations are human beings. Recently, I have been too lazy and almost forgot about this.

Now hiding here, idle is also idle, Fang Jifan began to fight the idea of ​​getting the news for the first time.

So the next day, he simply shut himself in the room, and let Liu Jin secretly buy something.

There are zinc rods, sulfuric acid, and copper rods. After these are roughly prepared, install the sulfuric acid in a jar and seal ...

Zhu Houzhao saw that Fang Jifan couldn't close the door, tossing these, could not help but be curious, could not help but joined up and asked: "Lao Fang, what are you doing?"

Fang Jifan was very serious and just said, "Make battery."

"Electricity ... Battery ..." Zhu Houzhao said incredulously: "This is obviously a jar. What does it have to do with electricity? Even if it is related to electricity, it should be called an electric can."

Fang Jifan suddenly discovered that it was a waste of time to explain these to Zhu Houzhao, but ... I thought that Xiao Zhu Xiucai said something very reasonable. Isn't the early battery just a can?

Fang Ji nodded his head, and a moment later, this rough "electric tank" was made.

This is a relatively primitive battery. It first appeared in the eighteenth century. It is called a voltaic battery, but ... in this era ... uh, is it useful?

Of course, it is useless.

If it is used to make electric lights, it is not impossible, but the cost is too high, and it is too stupid to do such stupid things, but ... Fang Jifan thought of another thing ...

telegram……

Needless to say, the purpose of the telegraph is that this thing is simply an artifact for delivering messages!

Today, people send messages, the fastest is the carrier pigeon, but unfortunately, the security of the carrier pigeon is not high, if you do n’t pay attention, if the carrier pigeon is like a prince, slipping away, then you are like his father, except for wanting to die In addition, there is no way.

Secondly, since it is a fast horse, it can not only consume huge amounts of money, it needs to build a post system, it also wastes a lot of manpower and animal power, and it is impossible to deliver messages at any time. This round-trip along the way still requires a lot of time.

But the telegram is different!

At this moment, Fang Jifan wanted to know the news. The next moment, the other end could send it. This is an artifact.

To make a telegraph machine, the first problem to be solved is the battery problem. The manufacture of voltaic batteries is very simple, especially this is the Ming Dynasty. At this time, Daming has first extracted zinc. This stuff is known as Japanese lead in this era. This is because most of the zinc in the Ming Dynasty was extracted from Japanese silver imported into Daming.

With this, plus sulfuric acid and copper, basically, a simple voltaic battery can be made. In this way, even if the battery problem is solved, the telegraph is even simpler. Just find a board and a Enameled wire, a long nail, a short nail, a copper piece, an armature can be.

Fang Jifan took the wooden board and laid it flat, nailed the long nails, and waited until the nails were exposed two centimeters before they rested. After that, they fixed the short nails on the wooden board and connected them with the armature. There is no copper wire drawing technique in the era, but it is not too difficult to manufacture as long as it costs the cost. The ancestors were able to draw wire on metal very early, so gold wire and silver wire appeared. The braid, this copper wire, was spent a busy day by Fang Jifan, and then connected the two poles of the battery to the 'telegraph machine', which was probably made.

Next, copper wires were laid, and there was no insulating rubber in this era, so people painted the wires and waited for the paint to dry, and it was considered to be completed.

After cutting down a dozen trees, Fang Jifan pulled the thread from one end to the other, and the other end was a utility room. Zhu Houzhao followed Fang Jifan's **** from beginning to end, looking at it curiously.

Later, Fang Jifan began to teach Zhu Houzhao's code. He first looked for a book. As a female parent, Zhu Houzhao, a professor who learned word by word, Zhu Houzhao learned something new all the time.

It's just ... What the **** is he doing? Zhu Houzhao is still somewhat incomprehensible.

Next, let Zhu Houzhao shine in another room outside Baizhang, where there is also a transmitter.

Zhu Houzhao looked at this ‘coarse’ machine and it was really rough. Anything in the palace was much finer than it. Zhu Houzhao did n’t take it seriously!

But he knew that he would know the answer soon, so he sat firmly!

Suddenly, there was a clicking sound from the transceiver.

Zhu Houzhao exclaimed.

Damn it.

He was scared to jump.

The electromagnet that surrounded the copper wire was just ... It was clearly shocked, and it made a sound.

Behind him, Liu Jin calmly ate fried soybeans, disapproving.

It seems that apart from hunger, nothing in the world can scare Liu Jin.

Zhu Houzhao shouted with a bit of horror: "Liu Banpan, Liu Banpan, have you heard the sound of the click? I heard it, this thing will move."

"His Royal Highness, the slave-maid heard it and saw it move." Liu Jin's voice was calm and calm.

"It's terrible!" Zhu Houzhao approached the transceiver curiously.

Liu Jin grabbed a bean and stuffed it into his mouth, looking at it easily.

The next moment, I saw that the electromagnet vibrated again, this time it was the third sound, click click ...

Zhu Hou looked after the head. After the electromagnet vibrated, it struck on the short nail on the wooden board, which made a knocking sound.

Zhu Houzhao widened his eyes and said: "It moved again."

"The slave maid saw it!" Liu Jin said calmly: "The slave maid remembers Du Wei letting His Highness take notes."

Zhu Houzhao suddenly slapped his forehead: "Yes, patronizing the hell, he forgot this."

So he quickly raised the pen and wrote down a two and a three.

Afterwards, the transceiver shook continuously.

Zhu Houhao made a full set of dozens of numbers, each with four numbers.

Zhu Houzhao finally got used to it, for example, he calmed down a lot and said, "Wh ... what about that mother?"

Liu Jin took out her female parent.

This is the most common "Spring and Autumn".

Holding the female parent, Zhu Houzhao began to translate the first set of numbers according to Fang Jifan's method.

Two three nine four.

Zhu Houzhao held a number and said something in his mouth: "Page 23, column 9, the fourth word ... Um? This is a" dian ".

Zhu Houzhao seemed to be surprised by the discovery of new things, and was happy: "Haha, something interesting."

Then he translated the second and third characters.

Eventually, these words came together.

"Are you hungry? Hurry ... back!" Zhu Houzhao wrote the number of words translated on the paper.

Zhu Houzhao suddenly raised his eyebrows.

I patted the case and smiled, "Haha, it's interesting, you see, the old man asked if the palace was hungry ..."

With that, he took the note he had translated and ran back to Zhuangzi breathlessly.

In Zhuangzi, Fang Jifan was sitting seriously in front of the transceiver, looking very serious.

He heard Zhu Houzhao shouting: "Lao Fang, Lao Fang ..."

Fang Jifan has the feeling of a Japanese dog, so let's talk about our code exchange.

"Your Highness ..."

Zhu Houzhao said happily: "This palace is here to tell you, this palace is hungry, what shall we eat at noon?"

Fang Jifan's face pulled down: "His Royal Highness, you should return to me there."

Zhu Houzhao was a little dizzy, how come back?

He remembered it again and slapped his forehead again: "Ah, forget, forget, you wait, this palace will go back to you."

So he panted back to his hut and sat down anxiously!

On the transceiver, there is a small copper key, connected to the battery of the Tao urn. He first took out his female parent, first found the word he wanted to speak, and turned it into a number, seven three six five.

Then he pressed the copper key seven times in a row, and every time it pressed, the current passed through the transceiver and made a clicking sound.

What he returned was that the palace was hungry and what to eat at noon.

He wanted to say, what are we going to eat. It's a pity that although "www.wuxiaspot.com ~" was found in my mother's book "Spring and Autumn", my words weren't found, and the word "what" was naturally absent.

This transceiver, inherited from the mother's "Spring and Autumn", is relatively advanced, so even communication has to become elegant.

Fortunately, there are not many characters in the Book of Songs. If the Book of Songs is used as the mother, it will be more advanced.

After sending out the code, Zhu Houzhao began to wait patiently. He was anxious and his eyes widened. Seeing that the transceiver had no news, he wanted to eat it. He even wanted to follow this line to find Fang Jifan and urge him. a bit.

Finally, Fang Jifan responded.

"His Royal Highness, he thought, we will have no food at noon."

Zhu Houzhao froze, no food, what does it mean, there is no rice in the tank?

He returned: "Why?"

Fang Jifan responded word by word: "Duke Xiao is at the door of the court."

"..." Zhu Houzhao ... scared to pee.
