Lossless "optical path" is a complex large-scale project, more complex than A, but once it is built, it will be a matter that will benefit the present and the future.

It’s like replacing the current optical fiber with a lossless optical path of silicon crystal. As long as your hardware device can support it, downloading a 10g movie will definitely be faster than the fastest friends.

However, the towers are rising from the ground, and I haven't even taken the first step yet.

Han Yi drove around and came to the teaching and work building at Beidamen. Song Yunxiang was standing quietly under the ginkgo tree waiting. The Xiyang scattered on her body, and her whole body was bathed in a layer of golden light, looking so out of the dust.

Just then, a royal blue Volvo slid to her side quietly, and the window on the right lowered. Han Yi, who was sitting in the driver's seat, shouted: "Get in the car."

Song Yunxiang stood still and asked, "Where are you going?"

"Go and get the materials."

Song Yunxiang hesitated and got into the car, fastened her seat belt and sat there without saying a word.

The car started slowly and went out of the gate to the Tianyi Club.

On the way, Han Yi joked: "I just saw you from a distance, just like you as if you had become an immortal. You are so beautiful."

Song Yunxiang casually said: "Actually, I don't look good, but others don't think so."

"I have never seen someone so...confident." Han Yi said speechlessly.

There was a smile in Song Yunxiang's eyes and she turned her head to look out of the car.

It is the peak period for get off work, and the traffic is full of traffic, and the sound of cars is whistling one after another. There is a traffic light ahead. Han Yi stepped on the brakes and said, "By the way, why do you take a long time to send a message every time, or even ten days and half a month to reply?"

“Because I rarely use chat tools.”

"Why?"

"Because... there are often irrelevant problems thrown over."

Han Yi broke the casserole and asked to the end, "What about?"

"If you are here, what are you doing?"

Han Yi smiled awkwardly because he liked to ask "Is it here or not" before sending a message.

"Then you just answer."

The light came up, and the car moved forward. Song Yunxiang said seriously: "How do you want me to answer?

I said I was there and asked me what to do if I borrowed money? I said I was not there and what to do if I invited me to dinner? So I just said it directly, so that I can know whether I am here or not."

Han Yi couldn't hold it in for a long time and laughed out loud.

The longer you get in touch with Song Yunxiang, the more you will find that she is actually a humorous person, the premise is that you don’t have unreasonable thoughts and you will not be hit by tons of blows.

...

Tianyi Experimental Building.

After Song Yunxiang got out of the car, she looked around and said curiously: "Where is this?"

"Tianyi Experimental Base." Han Yi locked the car door and said.

Looking at the two buildings hidden among the lush trees, Song Yunxiang had a hint of surprise in her eyes and asked, "Your?"

"Yes! Mine."

Han Yi looked proud on his face. Half of his property he had worked hard for more than half of his life was spent in these two experimental buildings. I dare not say that the equipment inside is the world's top, but it is definitely the best in China.

The two walked towards the building, and Han Yi personally explained on the way, "Building No. 1 is the main building of A Experiment, and Building No. 2 is material stripping."

Song Yunxiang asked: "Second-stripping of silicon light crystals? What is the purpose for?"

Han Yi glanced at her and smiled and said, "Do you also know the secondary peeling of silicon crystals?"

Song Yunxiang glanced at him without saying a word.

Han Yi touched his nose and explained: "Augmented reality consumes a lot of power, especially when playing games. The 2,000 mAh battery can support about 30 minutes, which is obviously not suitable for mobile devices, so I plan to use photovoltaic solar on the bottom plate of the mobile phone. The main problem at present is that the bonding strength of the silicon crystal eva and the TPT back plate is not enough, so a multi-layer peeling experiment is required."

After he finished explaining, Song Yunxiang was shocked and asked: "How do you make sure that silicon crystal eva will definitely be better than eva?"

Eva is a rubber foam material made of ethylene, which is often used in the bonding layer in the middle of solar panels.

Song Yunxiang asked this because every process of mainstream solar panels has been completed after thousands of tests. It is no problem to say that there is no need to change it. Now Han Yi directly peels off the silicon optical crystal. Does it mean that there is already a finished product? Or does he know the final result?

"What the researchers told me." Han Yi said vaguely.

"Can I let me see him? I want to ask him a few questions?" Song Yunxiang asked with anticipation.

"Oh, I'll ask him back, but I don't have much hope."

"Why?" Song Yunxiang broke the casserole and asked to the end.

"He has a weird personality and doesn't easily see outsiders."

Just in front of me, I arrived at the silicon crystal material room. Han Yi went up to check his fingerprint and entered the password. With a "click", the double-layer telescopic security door shrank into the wall.

The room seems to adopt a dust-free low-temperature design, and air conditioning appears the moment the security door is opened. Looking at the room, there are about 20 square meters, and there are several rows of stainless steel shelves against the wall, each row of five layers, each layer of five grids, and there are 20x20 black boxes in the grid.

Han Yi walked to the shelf and checked his fingerprints. The box opened with a "click" and inside were pieces of multi-layer silicon crystal experimental materials imported from the United States.

This box of multi-layer silicon wafers is priced at up to US$120,000, and you have to buy a complete set of experimental equipment, not to sell them separately.

"How many pieces do you want?"

After hearing Han Yi's words, Song Yunxiang thought of an important thing: Experimental silicon wafers are expensive, so isn't it good to just take them away?

"How much does it cost?"

Han Yi went with the water and said, "How about this, you will do experiments here in the future, and these silicon wafers will be considered by me to sponsor you."

Song Yunxiang glanced at him and said, "Are you messing with me?"

Han Yi smiled awkwardly and said, "You're thinking too much, am I that kind of person?"

"yes!"

Seeing Song Yunxiang's alert look, Han Yi said with a three-point intrigue: "There is complete equipment here, and the scientific researchers are also first-class in China, and there is still the opportunity to get into the most cutting-edge international technology. The school does not even have complete equipment, so who do you communicate with?"

Although she was moved, Song Yunxiang didn't want to be persuaded by him so easily, saying, "I'll go to the University of Science and Technology."

Han Yi said proudly: "We are in a joint laboratory with the University of Science and Technology, and Professor Zheng Peisheng is almost my supervisor."

Without waiting for Song Yunxiang to continue, Han Yi put on gloves and took out four or five pieces of experimental silicon crystals, saying, "Let's go, why should the alarm sound?"

When I came to the Silicon Crystal Laboratory on the fourth floor, I looked at the professional experimental equipment inside. Many of them were specially customized. Song Yunxiang couldn't take any steps and never mentioned the University of Science and Technology again.

Han Yi taught her various equipment operation methods step by step.

Song Yunxiang is really a good student. She passes everything over again, and you don’t need to say it again. When the experiment was in the process, she was like a cheat, and she was extremely skillful. Just Han Yi, who had been in the laboratory for more than half a month, was a new girl with her.

After two sets of experiments, Han Yi said: "It's getting late, let's come back tomorrow."

Song Yunxiang, who was standing in front of the test bench in a white coat, frowned and thoughtful, said without looking back: "You go back first."

"I'll go back first. You haven't obtained an identity authentication yet. The security guard must send you to the police station."

Seeing that Song Yunxiang was still hesitating, Han Yi said, "Let's go! Rome was not built in one day, and it's not too late to come again tomorrow."

Song Yunxiang reluctantly left the experimental building with him.

...

The next morning, Han Yi went to the real estate trading center to complete the transfer procedures. In the afternoon, he took time to help Song Yunxiang with an identity certification and asked her to sign a so-called "disclosure agreement".

Song Yunxiang always felt something was wrong, but there was no problem with the agreement. She didn't intend to reveal any secrets, so she signed it after thinking about it.

After signing the letter, Han Yi left with a strange smile on his face. He kept Song Yunxiang in the laboratory for a while, then threw it behind and buried his head in the experiment.

Of course there is nothing wrong with the agreement, but signing the confidentiality agreement means that she will always stay in Tianyi Laboratory. She does not spend a penny and "scam" a talented woman with a super high IQ to work. Can Han Yi be unhappy?
