Three Kingdoms: Me! Liu Zheng! Queen Jing of Zhongshan!

"This, the current development is to develop a machine that can also speak loudly, but it is ......unstable,"

Ma Jun said weakly.

Then he took Liu Zheng and others to a room and saw the radio station made by Ma Jun on the table.

The body is very large, and there are equipment up and down, what makes Liu Zheng pay attention is the familiar appearance of the bell on the table.

Liu Zheng fell into deep thought for a while.

It seems that our country has mastered some physical laws for a long time, but it has not yet formed a theory.

After all, if we have not mastered some laws of physics, how can we know how to make a handset microphone into a bell-shape

? The reason why this is the case is not because the sound effect is better in this way

? In ancient times, there was such an awesome technical ability, why did there not be any Archimesio, Newton, and Wright brothers who resounded all over the world in later generations?

The accumulation of experience in practice, coupled with some traditional habits of passing on to men but not to women, and not easily passing them on to the outside world is related.

This has also led to the fact that many technologies that have surpassed the world for many years in ancient China have not been recorded in writing.

And those who passed it on were all passed on by word of mouth and taught by their own hands.

But if there is an accident and the heir dies, the craft will be cut off.

In order to prevent this kind of thing from happening again, Liu Zheng has long ordered that all technologies should be recorded in writing, and even if there is no successful technology when doing experiments, it is necessary to carefully describe the effects of its failures! After all

, failure is the mother of success, and if countless roads of failure are ruled out, will the road to success be far away?

Liu Zheng sat straight on the table, a loudspeaker with a word written on his ear, and a horn with a word written on his mouth in front of his mouth.

"How do you open it?"

"Click here, there is a sizzling sound in your ears, it is on."

Ma Jun stretched out his hand to turn on the switch, and the sound of the horn in Liu Zheng's ears came out.

"Zizizi

" "Hey, hey, is there anyone?"

Although he didn't know if there was anyone on the other side, Liu Zheng couldn't help but shout.

It's like a lot of people can't help but pick up the phone when they see a phone call, it's very spiritual.

"Lord......" Looking at Liu Zheng's appearance, Ma Jun didn't dare to say it for a while, the opposite side has not been opened yet, only this one.

Because this is a test thing, it will only be opened when you start doing experiments.

After all, the power supplied to it is only a little bit, and unless someone is watching the power supply, the power supply may be interrupted at any time.

Because the power supply of this test machine is a small man-made waterfall, it is also a timer drip and the water that flows down drives the generator to generate electricity and supply electricity.

The advantage is that the flow rate can be artificially controlled.

The disadvantage is that if there is not enough water above, or if it runs out, the generator will not move, and there will be no electricity, and people need to keep an eye on it.

It's not that Ma Jun doesn't want to make it bigger, after all, they haven't tested it.

They built a giant watermill to generate electricity, using rivers to generate electricity, and as soon as they connected to the radio, they directly broke the radio.

After many tests, Ma Jun found that this mode is now in the best state!

Although the sound will be a little rustling through the past, at least it will not burn the radio station.

Although he didn't know what the reason was, Ma Jun knew that he couldn't use a large generator to supply electricity.

"Well, there's no sound on the other side, either it's not on, or it's broken, so let's turn it on if it's not on.

Liu Zheng listened for a while, put down his things, smiled at Ma Jun, and said innocently.

"So the lord knows?" Ma

Jun said secretly in his heart, and then hurriedly responded.

"Okay, I'm going to drive another one. Saying

that, Ma Jun didn't wait for Liu Zheng to respond, turned around and went to another room, and at the same time ordered someone to add water to the device to prevent Liu Zheng from being silent halfway through the wait.

"Hey, hey, hey, hey~ did the lord hear it~z~?"

Liu Zheng held the earpiece and waited for the sound to come, although he had known about the radio for a long time, and even used a mobile phone that was more high-tech than the radio.

But the radio voice sounded, in this era, this is

the first time! For the first time in history, how can Liu Zheng not be excited?

"I can hear it! I can hear it! I am Dong Qi, I am Dong Qi

, please answer when you hear it, please answer when you hear it!" For a while, the words engraved in the blood came out.

Ma Jun was stunned when he listened.

"Knock, knock, no~ I can hear it.

"Hahaha, okay, come back." Liu Zheng listened to Ma Jun's reply, laughed, no longer embarrassed Ma Jun, and let him come back.

Putting down the things, Liu Zheng waited for someone to come over, Ma Jun saw that Liu Zheng was waiting for him, and hurriedly stepped forward a few steps and shouted respectfully.

"My lord.

"Hahaha, I didn't expect you to be so powerful at a young age, not bad, I will reward you with two catties of sweet potatoes!" Liu

Zheng patted Ma Jun on the shoulder, looking old, as if he was from someone else's family.

Ma Jun smiled on his face and scratched his head.

(The year of Ma Jun's birth and death is unknown, the Battle of Guandu was his improvement of the trebuchet under Cao Cao, and the Battle of Guandu was almost 200 years old.)

According to the time required for technical learning at that time, plus the lack of age to be able to do a certain position under Cao Cao, I arranged that Ma Jun was born in about 165, 35 years old in 200, and now at the end of 188, according to 189 years, he is 24 years old.

Huang Xu rolled his eyes, Lord, you are only 20 (169) this year, and Minister Ma is already 24

, older than you! Why are you embarrassed to say this sentence that people are young?!

But Huang Xu also complained in his heart, and it was impossible to say it.

"Ma Jun, you still have to study this electricity carefully! This instability is largely due to electrical instability.

Liu Zheng looked at the honest and honest Ma Jun and kindly reminded.

Although I know that it is the current instability and voltage problem

, I just know it! I don't know how to change it at all!

In order not to show timidity, Liu Zheng chose to be a vague god stick character~

"Lord, doesn't the one-man radio equipment have batteries?

And before Liu Zheng could speak, Ma Jun shook his head, "It can't be used, I tried it, but there was no movement, and after putting it on this radio station, the battery can't be used for a single device."

Obviously, Ma Jun had done experiments, so he opened his mouth and immediately answered Huang Xu's doubts.

"Can't you make it bigger?" Huang Xu was unwilling and said again.

Huang Xu's words made Ma Jun frown, it seems that Ma Jun didn't think of this, Liu Zheng watched the two have a back and forth conversation, and did not interject, looking at them quietly.

After all, I don't understand it very well, so don't mix it up, if you say it wrong, it's easy to let yourself collapse in their omniscient appearance.
