After sending the ladies to Feng Yan's house, Cheng Yongxing began to check the information when he returned.The next day, he spent a whole day in the library.

In his mind, these classmates are always different from others.

In his previous life, he did not have the opportunity to do anything for them. Even if he returned to China for a few occasions, he was treated as a treat by his classmates.This time he was able to put out a lot of power.

After searching for information for several days, Cheng Yongxing really found two suitable directions.

However, which suits Hao Yunli may need to be decided by herself.

———————

Hao Yunli knew that her old classmate had been in the library these days, but she did not urge.

She is not afraid of writing essays and projects.

However, the publication of significant papers within a limited time can only be guaranteed unless you have your own laboratory, sufficient funds, and manpower.

She has just stepped into the scientific research field, but her reputation is not obvious and it is very difficult to obtain projects and funds.

Professor Niu’s suggestion gave her new hope, but as time passed, her hope disappeared little by little.

But there is nothing to think about it, it is impossible for you to go smoothly every step!She is only 21 years old, take it easy.The accumulation of prestige is exchanged for time and sweat.

It took nearly 30 years for Professor Edward to have his own laboratory.

Hao Yunli simply relaxed and took advantage of these few days to take a good turn around the ice city.

She studied in Bingcheng and lived not long.Although she spent her freshman year here, she did not know the city very well due to her heavy studies and harder scientific research projects.

She also followed the class for group activities and visited some city attractions.But there are also some people who are watching the flowers without leaving a deep impression.

On July 15, Feng Yanjia.

Early in the morning, Hao Yunli and Feng Yan had breakfast, and they were going to Central Avenue to take some photos.

In two days, Hao Yunli and Zhao Mengjia were ready to go back.Take a few more photos this time, and come back later, not necessarily when.

Zhao Mengjia's affairs, I have met with Yuan Shuai, after they go back, they will contact the school to discuss the joint experiment of the two schools.

The door knocked before a few people went out.After opening the door, it was Cheng Yongxing!

He drove up early in the morning and blocked the girls at home.

"Hao Yunli, do you have time today to go to the MEMS laboratory and do some experiments together. You have some ideas, you go and see?"

Cheng Yongxing has determined two directions in the past two days, one is a CMOS camera.

Later generations in this field have also been developing, but it is more about the development of craftsmanship and the continuous improvement of details.Technical value, the value of the paper is not too great.

Another one that is considered very promising is the bioassay chip.

This topic is still a hot topic even after 30 years.A large number of papers continue to appear in this field.

People kept giving talks on TED, introducing what bioassay chips they had made, and there was a round of applause.

Among these, the most commonly used is the blood glucose meter.After Cheng Yongxing was middle-aged, because he needed to monitor his blood sugar, he had a blood glucose meter at home, which was very convenient to take a few weeks.

The most important thing about the detection chip in this regard is not the detection technology, but the system integration, miniaturization and integration of various detection components.

This is also the strength of MEMS.

1992 was the eve of the explosion of handheld devices.Entering this field in advance cannot see immediate benefits, but for academia, it is the right time.

Several people came to the MEMS laboratory. On the table was a desktop blood glucose meter used in hospitals and a smaller portable blood glucose meter.Cheng Yongxing pointed to two instruments, "Our work in the next few days is to make this machine into a chip."

Blood glucose testing, with the gradual increase in patients with hyperglycemia in the society, has gradually become a regular item in health monitoring.In order to meet this demand, the size of blood glucose meters is gradually shrinking.

In 1992, some portable blood glucose meters appeared on the market.

However, these blood glucose meters are still large in size and can only be used on a table.More importantly, they still have problems such as complex testing procedures and long waiting times.

For the operator, each test requires 2-4 steps of complex operations.Due to the complex operation process, the target population of these systems is hospitals or intensive care patients.

What Cheng Yongxing hopes to do is to meet the standards of commercial blood glucose meters for later generations, 1. Highly integrated, smaller, 2. Reduce testing steps and testing time, get the results in one step, and get results in a few seconds.

————————

Looking at the large and small instruments on the table, several girls were stunned.

Hao Yunli was the first to react.

"May I?"

She spent nearly 2 years on MEMS and immediately realized the value of it.

"can!"

Sun Yan reacted: "Really?"

"Really!"

Zhao Mengjia also reacted, her eyes widened: "This is really okay?"

Hearing the same question and repeating it for the third time, several people laughed.After laughing, all three of them looked at Cheng Yongxing, waiting for the answer repeated for the third time.

He did not answer this time, but went to the blackboard, picked up the chalk, and started to draw.

With a simple schematic diagram slowly taking shape in chalk, Hao Yunli and Sun Yan's eyes lit up.Both of them have experienced the baptism of the industry and know what this simple schematic represents.

Zhao Mengjia is still in a simple state of pedagogy, carefully looking at the schematic diagram, and then calculating the feasibility.After Cheng Yongxing finished drawing, he pointed to the function modules on the blackboard and asked.

Sun Yan stood there again and said nothing.

————————

The discussion between Hao Yunli and the others came to a close, and asked in a low voice, "Is this project for me?"

"what did you say?"

Cheng Yongxing was still discussing with Zhao Mengjia, and heard what she said, but did not hear clearly.

Hao Yunli swallowed and asked loudly, her voice was so loud that she was shocked.

"Is this project for me?"

The benefits of this project are by no means lower than MEMS.

This is a paper that can be listed on the CNS.It's enough to reach the top and send her to the sky.

"Is it for me?"

She had to be cheeky in front of two good friends to confirm this matter again.

"Of course, I thought about this idea for three days, what do you think?"

"Okay, of course, let's experiment now?"

Hao Yunli came with interest and walked to the blackboard to perform silent mental arithmetic.She is calculating where and how to start.

The room was very quiet, and no one spoke.

Cheng Yongxing silently picked up a test bench, found a drawing, and drew it on the paper.

Feng Yan looked at him, opened his mouth, and gave up.Finally, he walked up to him, picked up paper and pen, and acted as his assistant.

During the whole process, she didn't ask a word.

Apart from the rustling of pencils, the room was quiet.

————————————————

Cheng Yongxing's experimental method is not much better than the three ladies.

Although he has not done less in recent experiments, he still lacks determination.After all, the focus of his work has shifted to being a leader, rather than doing it himself.

In general, it may be better than Zhao Mengjia, but compared to Feng Yan and Hao Yunli, it is not even a bit worse.In the end, the main work force was changed to Hao Yunli and Feng Yan, and he was just on the side to fight Zhao Mengjia.

After three days of work, this simple, proof-of-concept chip is ready.

Cheng Yongxing pricked his index finger with a needle, squeezed a drop of blood on the glass and sent it to Hao Yunli.

The experiment can begin.

————————

At 3 pm on July 22, Bingcheng Railway Station.

The window in the box is down, and nothing can be heard from the outside.

Hao Yunli moved to the opposite side and worked hard with Zhao Mengjia before lifting the middle window, sticking her head out of the box and shouting, "Go back!".

The train has slowly started.

Cheng Yongxing, Sun Yan, and Yuan Shuai waved their hands on the platform, surrounded by people seeing off.

The train was getting faster and faster, and the two people finally retracted their heads.Hao Yunli thought for a while, then stretched her head out again, and the probe yelled, "Thank you!"

She has said these two words countless times these days.But she still wanted to say it again.

————————

Hao Yunli never asked that question, these were not important anymore.

Knowing that Cheng Yongxing already has a girl she likes, she is not ready to intervene.

Maybe the fate of the two people is waiting for the next life.

If there is an afterlife.

The biggest gain from her visit this time was not just a good idea.More importantly, she knew that he always had her in his heart.

that's enough.

That secret will be buried in her heart forever.That is a secret only she knows.

Hope that in the next life, she can recognize him first.

There are too many unexplainable things in this world, some are fate, some are destiny.

......

"I bet my youth on tomorrow. You exchange your true feelings for this life. You don't know how much sadness is in the world over the years, why not go for a chic..."

The girl's crisp singing sounded in the box.

————————

Following the flow of people, several people have already walked towards the exit.Hearing Ruoyuowu in the wind, Cheng Yongxing raised his hand and waved it.

Out of the station, I found a Jetta, and a few people drove back to school.

In the past few days, Feng Yan has been experimenting silently and rarely speaks.

She has been hesitating.If next semester, she does not go to the Ph.D., will things turn around?

She didn't know the answer either.

Yuan Shuai didn't understand the situation. He has been visiting several factories and gathering with classmates these days. He didn't even understand what the girls were doing.

The school is not far from the railway station, and it will arrive in a while.

"Where are you going? Take you home directly? Or go up and see?"

After Yuan Shuai got off the car, Cheng Yongxing looked back and asked.

Feng Yan sat there and didn't answer directly. Instead, he said, "It's nice to have a friend like you!"
