"Yes, father...father, that's exactly that!"

Fusu immediately said, "It's exactly the same as what Mr. just read, it's not bad at all!"

"Wow? So awesome?"

Ying Zheng couldn't help but be curious, "How come this is written?"

"This is the printer."

Zhao Long smiled and said, "Enter instructions in front, and you can operate through machinery and equipment later."

"Magic, indeed magical, how did this be done?"

Ying Zheng said in surprise, "This is also physics and chemistry?"

"This should be considered part of physics, called mechanics." 81Zw.????m

Zhao Long smiled and said, "Actually, I use mechanics and electrical mechanics. Both of these are physics. I use machinery to operate in the front, and behind it is through small units of resistive wires to allow electricity to operate the machinery behind.

Finally print out the words.”

"Oh, but that's the case..."

Ying Zheng sighed after hearing this, "This physics is really a good thing."

"really……"

"indeed……"

When everyone heard this, they nodded.

"This, but..."

Seeing this, Chunyu Yue couldn't help expressing his doubts, "I just saw that when I used this printer to write these words, it was not very fast... If I wrote it faster, it would be much faster than this one.

...Sir, this thing is still so complicated, is it available?"

Um?

After hearing Chunyu Yue's words, Ying Zheng couldn't help but glared at him, "If you don't understand, don't talk nonsense! You old man is really a shame! You are so ignorant! Can you do useless things? What you do

Isn't it useful? Li Si, tell him, what's the use of this thing?"

"No...Sir, is that...huh?"

Li Si was stunned, smiled bitterly, and said carefully, "Village Chief, I don't know this..."

That’s right, don’t ask me. It’s the first time I’ve seen this thing. I really don’t know what it is for when you ask me!

"This is, too..."

Ying Zheng nodded slowly, then looked at Zhao Long, "Sir, what other... miraculous effects does this thing have?"

"Hey... I knew you would ask that."

Zhao Long smiled and said, "If Guangguang only wrote this thing once, it would be better to write one by hand. But..."

As he said that, Zhao Long put the quiet Ye Si down on the bottom of the other table and pressed a switch next to it, "Look at it!"

After he pressed it, the printer automatically started to move again.

Didi...

Crack creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak creak

Soon, another piece of paper with Jingye thoughts was also pushed out.

hiss?

Seeing this scene, everyone was stunned.

Damn?

why is that?

Mr. Biming no longer slaps his hand, and he can still come out again as it is?

Then, Zhao Long pressed it again, and the third quiet night thought was printed out.

Wow?

Everyone was shocked when they saw this scene.

Totally shocked!

"How about it?"

Zhao Long asked with a smile, "Teacher Cun, I can see a few points by pressing the button a few times. Moreover, this word is rare now, but if I write a lot of dozens and hundreds of words,

Then you can still print it out, and there will be no more time. Teacher Cun, do you still think this thing is the same as handwritten?"

"This is certainly different, this is very different!"

Chunyu Yue said in surprise, "Great fortune, this is really a great fortune. Sir, how did this do it?"

Everyone was also surprised to see this.

How did this thing work?

Why is Zhao Long obviously no longer doing it himself, but this machine can "write" the things Zhao Long originally entered over and over again?

Strange, this is really strange!

"Sir, tell me!"

Li Si was also extremely curious. This thing was so magical. How did he do it?

"hehe."

Zhao Long smiled and said, "We don't have any optical sensors or special chemicals here, so I used a basic principle, which is the principle of conductivity."

Um?

Conductive?

Everyone was stunned when they heard this, looking at me, looking at you, they were puzzled.

What does conductivity have to do with this?

"Sir, please explain it?"

Ying Zheng asked.

"In fact, this part of the function is called a photocopier."

Zhao Long said with a smile, "The printing ink I used is electrically conductive."

What?

This printed ink is still conductive?

After hearing this, Ying Zheng and others couldn't help but take another step back.

"Why?"

Seeing this, Zhao Long was stunned at first, then smiled, "What are you afraid of? I have adjusted the current on this printer, and it won't kill anyone!"

"But that's the case..."

After hearing this, Ying Zheng and others smiled.

You didn't say it earlier...

"Sir, please continue to talk to us, why is this?"

Li Si said.

"Yeah, OK."

Zhao Long smiled and said, "I have mixed things that are easy to conduct electricity in the ink. Through the current drain gate, I can decide whether the ink is placed or not.

As long as the metal head above that piece of paper passes through, the places with ink will be conductive, and where there is no ink will be conductive, that is, the current will not pass.

The small squares with ink printed in the place where the electric current passes will press down, just like the seal.

Where there is no current, it is blank. This adds up to form a word.

As for the ink, there are small holes inside, which can be continuously transmitted through siphons from the ink pond above.

This head is too fine, and it takes time and energy to be completely precise. I use the slightly larger machinery behind it to provide power and try to ensure no mistakes.

After all, we don’t have any sensors here, so we can only do this. Moreover, because I can’t do this thing too carefully. I have tried my best to make a 20×20 board as a Chinese character spray head, as long as we don’t

It should be fine to make some particularly complicated Chinese characters."

"oh……"

After hearing this, everyone was half-understood.

I understood, but I didn't understand it completely, but this did not prevent them from understanding a general principle.

No wonder everyone looked at the shape of the Chinese character, and it turned out to be for this?

"Oh, sir, really is a talented man!"

Ying Zheng couldn't help but sigh, "This is indeed a treasure, it is indeed a precious treasure!"

"Hey, it's not that great."

Zhao Long said with a smile, "The people outside look down on this thing at all. After all, he also has an error rate, and the picture quality and effect are not that good... Fortunately, we can use this kind of thing here!"

That's right, after all, I'm not a professional, so I can only achieve this effect.

"Hey! How could that be said?"

Ying Zheng said, "As the sir said, we need this thing very much, so he can be said to be worth a thousand gold!"

Oh?

Still worth a thousand gold?
