"I'm mainly doing pre-promotion, with the support of venture capital funds, so as long as you sell it, the sales will belong to you. ”

Li Lechen said to Erdan.

What "pre-promotion", what "venture capital fund", Ergou heard it in a fog, and understood that he didn't need to pay any money, as long as he sold it for 100 yuan according to the requirements, the 100 yuan would belong to him.

This is simply more empty than an empty glove white wolf, who does not agree is a fool.

However, a small machine is used to quickly sort out beads of different colors, and Erdan really doesn't think this machine is worth a hundred yuan.

But even if you can't sell one, you won't lose money.

So after repeatedly confirming with Li Lechen that he didn't need to advance any funds and didn't have any risks, he loaded thirty machines, and Erdan began a new day of walking the streets.

Although Erdan sold this "chromatographic distinguisher" for the first time, he knew how to keep an eye on the market, so he went directly to the aunts who were gathering at the door to do handiwork.

"One hundred yuan a piece, quickly sort beads, try it for free, don't pay if you're not satisfied!" Erdan shouted loudly with a megaphone.

Free trial or something, it belongs to the lively things to see.

Soon a lot of people gathered around.

In order to prove that this machine is easy to use, Erdan personally experimented, a large bowl of mixed-color beads, poured in at the inlet, and poured out at the outlet, only for more than ten seconds, and each color was clearly distinguished.

If you don't talk about practicality, just looking at the process, it's really interesting.

So while everyone watched the excitement, many of them also took videos and uploaded them one after another.

Although it took a toss around, none of them were sold in the end, but with this popularity, the sales volume of Erdan's other products more than doubled compared to the past, which made Erdan completely unexpected. There is no advance in these machines, and they can be used to attract people, which is also a big gain.

So he shouted harder and performed.

At the end of the day, not only did Erdan sell three machines, but almost the aunts in the entire area knew about it.

......

Imperial capital, six o'clock in the evening.

Experts participating in the National High-tech Symposium are eating a buffet in the hotel.

"Professor Kim, your introduction today is really wonderful. A gray-haired old scholar stepped forward to greet Jin Jingcheng, and the two of them were cooking in the self-service food pick-up area.

Jin Jingcheng hurriedly said modestly: "Professor Liu, this is torturing me, you can be a master in optical physics, I can be regarded as a class axe." ”

Professor Liu was a little embarrassed: "Theory is theory, but being able to apply it to practice like Professor Jin still makes Lao Yu very impressed." I have thought about this kind of color sorting device before, and the theory is really not difficult, but it can only distinguish specific colors, and it is very strict. ”

There are too many types of colors, either each color is set, or there are only a few colors of beads, but obviously no matter which one of them, it is not of practical significance.

But the machine in my hand is different, that is, you can identify the color of the beads in advance, and then analyze it against it.

"In other words, does your machine automatically adjust the resolution by identifying the sample?" Professor Liu continued.

"Hmm...... Oh, yes. ”

Theoretically, this is the case, and Jin Jingcheng can only answer like this.

Of course, he also wanted to take it apart and take a look, how could such a small place be able to do this kind of setting? But the problem is that it can't be opened, it can't be opened!

Professor Liu spoke again: "I wonder if the old man can see the internal structure of the machine?"

"I'm afraid it's not very convenient. Jin Jingcheng refused, "I haven't applied for a patent yet, so I ......"

"Then can you lend me that machine to take a closer look?"

"Let's eat first......"

It's not good to refuse again and again, Jin Jingcheng can only change the topic.

The professor surnamed Liu was not reluctant, but he still followed closely, Jin Jingcheng chose a seat to sit down, and he also sat next to him.

Soon, the four-seater dining table was full.

Jin Jingcheng looked around at the large number of vacant seats around him, and then looked at the two who came later, and twitched the corners of his mouth.

The topic of several people is basically about the machine that Jin Jingcheng showed today, and everyone understands the theory, but it is also very incredible from a theoretical point of view to make such a delicate object.

"I'm really curious about that mini air energy. ”

"Is it any color that can be distinguished? Professor Kim didn't specify this today. ”

"I feel that Professor Jin's hands-on ability is also very powerful, and this machine is too exquisite. ”

"Today, at first glance, I thought it was something that was industrialized and mass-produced. ”

"The application prospect of mini air energy is very broad, it is an area that I have been researching, I wonder if I can discuss it in depth with Professor Jin?"

"Can you distinguish any color? That would require a huge data processing system. ”

......

Although what everyone said was related to themselves, Jin Jingcheng did not respond except for nodding and smiling from time to time.

He didn't say anything when he ate, he didn't talk when he ate, and no one said anything about him.

The point is, a lot of questions are really hard to answer.

Fortunately, there is still half a day to summarize tomorrow, and this meeting will be over.

It's impossible to apply for a patent or something, after all, I don't understand what kind of structure is inside.

It's just this time to be in the limelight, and after a long time, everyone may forget about it.

Keep eating.

Everyone continued to chat.

"Tick!"

Someone has a message coming in on their phone.

In the era of big data, what do you care about and what you watch on weekdays, and various information platforms will desperately push what kind of information to your mobile phone.

"Tick!"

Another person has a message push on his phone.

The two were a little embarrassed because they were talking about this topic that did not have a response from the main person, so they picked up their mobile phones and looked at it.

One is a short video, and the other is a local news.

However, the content that the two of them watched pointed to the same thing.

This thing......

Suddenly, the two looked at each other, and then looked at each other's mobile phones, and they couldn't help but gasp.

This thing was so common in Lingcheng that it was so common that it was sold in a street selling groceries, and they were experts in the academic field who didn't even know it.

Sure enough, it's a master in the folk!

But...... Take something that people don't know yet...... No wonder this Jin Jingcheng always flickered with words. Dare was not invented by himself at all.

Soon, both the video and the news spread at a very fast speed among a group of experts who participated in the academic seminar.

At the time of dinner, it was basically known to everyone.

Of course, Jin Jing is an exception, because no one will be stupid to pass these things directly to the parties. So after eating, Jin Jingcheng didn't know anything about the previous professor surnamed Liu: "Professor Liu, I'll go to your room later, in fact, I also have a lot of questions I want to ask you about this." ”

This time, it was the turn of Professor Liu to refuse: "That...... I'm suddenly feeling a little unwell, why don't we make another appointment?"

"Are you alright? Would you like to talk to the conference team? There should be an infirmary here. Jin Jingcheng asked with concern while being happy in his heart.

Professor Liu waved his hand again and again.

After that, Jin Jingcheng looked at the two enthusiastic professors before, but saw that they looked strange, and one of them simply threw his chopsticks and fled from the dinner table in a hurry.
