The first rebel of the Tang Dynasty

Chapter 570 Loudspeaker and Light

Everyone was quiet.

Looking at everything above, I began to think, what is this doing.

Until Li Yin tore off the top red cloth.

Only two big red letters appeared in front of everyone.

"Battery!"

Everyone read in unison.

This battery was previously reported in newspapers.

So, everyone seems to be very familiar with it.

But what is the use of this thing?
Everyone is still a little puzzled.

What about the auto show?What does that have to do with batteries?
When can I see the auto show?

Waiting for everything makes everyone puzzled.

Seeing everyone's confusion, Li Yin said:
"Battery, the literal meaning can be understood as a pool filled with electricity. As for what is electricity? It is a kind of energy, just like lightning, which also belongs to this category. It is extremely powerful. This thing can drive many things that make people feel amazing. It can change the lives of the common people and improve the quality of life. In general, it can be divided into five key words!"

Li Yin's approach is no different from the format of future press conferences.

This form is the most attractive.

He also took advantage of it.

The first is highly cohesive keywords.

Seeing everyone's intoxicated appearance.

As Li Yin spoke, he directly tore off a piece of cloth underneath.

efficiency!The word two appeared.

"First of all, it will bring great efficiency and make people's work more efficient! If the battery is used in schools, the army, and even the court, it will be a kind of progress!"

"So, what is the product corresponding to this kind of thing?"

Cheng Yaojin asked.

He was asking the point.

What is the corresponding thing?
"Hi everyone, the first corresponding thing is the loudspeaker!"

Li Yin revealed the product in front of him.

A loudspeaker appeared in front of everyone.

This is the existence that can make a sound.

And beside it, there is also a battery attached.There is also a microphone.

It turns out that it looks a little weird when it looks like this, but I got used to it after looking at it.

"It turns out that the loudspeaker looks like this! It's amazing."

"This thing is interesting!"

"It's hard to imagine that the sound came from here!"

"Mr. Zili is really amazing, he can make such things!"

"So where is the efficiency? How to say it? Or what is the example?"

……

Li Yin went on to say:
"The loudspeaker can be placed above the school. If the teacher is teaching, more people can hear his teaching clearly. This is the first. Put it on the army. It can be used during the military discipline. It makes tens of thousands of people practice at the same time, and if the court is notified, all civil and military officials will come. Isn't that very cool!?"

The last sentence he said was for Li Shimin.

Next, he will cheat him again.

Because he needs it, and a need can make money.

Not to mention anything else, just say that the latter function is very easy to use.

Install the loudspeaker on the Daming Palace and say directly into the microphone that all officials are coming to the morning court.

This efficiency is faster than what can be conveyed by others.

But it is hard for the officials.

Li Shimin's gaze became greedy.

It would be great if there was such a thing.

Therefore, he must be thinking in his heart that he must get it.

At the same time, the scene exploded.

This is good stuff.

These rich people have ideas of their own.

Wouldn't it be better if it was used to conduct Jiading or something?

Thinking of this time, they all wanted the existence of this loudspeaker.

At the same time someone asked.

"Then how much does this thing sell for?"

"Only one, let's put it up for auction! A loudspeaker, a microphone, and a battery will be given away. After the press conference, this one will be auctioned directly. After mass production in the later stage, the price will be determined."

These things have taken me a long time, and it will take a long time to mass-produce them.

Some time ago, he also set up a research institute.It's on the 28th floor, and not many people know the details inside. Zhu Shan and the others thought that there was the money maker, but this time it was shocking.

There are about a thousand people there, and everyone has their own business.

These things are made by them.

At the same time, this research institute is unknown to others, and the people recruited are also transferred from other places.

Of course, these people lived a very good life and were confessed.

He wasn't afraid that these people would leave, because they couldn't do anything without Liao Li.

Everyone's eyes became very urgent.

Li Shimin wanted it too, but he couldn't get in touch with Cheng Yaojin, otherwise he must be allowed to participate.

Otherwise, it will have to wait for mass production later.

He is the emperor, he should enjoy whatever he says first.

"Let's look at the second keyword!"

Li Yin lifted the third piece of red cloth.

Just touch the red cloth, it's still two words!

bright!

Now, everyone doesn't understand even more, what is light?

Isn't the light just now?

Waiting for people to react.

Suddenly, dozens of people rushed directly to the floor-to-ceiling windows and drew the curtains.

The whole room immediately became black and dense.

Everyone panicked, this is the fear of the dark.

Facing the darkness, people don't know what to do.

What if Li Yin wants to kill them?
Then their money is all in Shengtang Bank.

They have nothing left.

At this time, there was a little confusion among the crowd.

This little confusion didn't last long, only a bright light appeared in front of his eyes.

The lights above everyone's heads lit up, and the whole room was like daytime.

Li Shimin saw clearly what was above his head, wasn't it the ball he saw just now?
This thing really lights up.

It is somewhat different from biogas lamps.

The biogas lamp still had a light, but there was none here.

"This is a light bulb, powered by batteries!"

Li Yin lifted the cloth strip of the real thing, revealing a high-brightness light bulb.

Everyone suddenly realized.

Just three things today made them feel wonderful.

It turns out how ignorant I was before.

It turns out that the role of this battery is so great.

Li Yin went on to introduce:
"The light bulb can be placed in any dark place, and it will bring light there. No matter where there is a light bulb, there will be light. At the same time, no matter how strong the wind is, it will not affect its brightness. It has no peculiar smell, and it can be used for more than ten years, which can be said to be an upgraded version of the biogas lamp."

Most of the wealthy people at the scene used biogas lamps.

Although it has light, but due to the recent low temperature, it is cut off from time to time, so the brightness of the light is not high.

It would be wonderful to have this lamp.

Someone asked: "Then how to get this light bulb?"

"auction!"

Li Yin only said two words.

Another auction!

It seems that Li Yin only has money in his eyes.

But Li Yin hadn't finished speaking yet.
