Just when Qiao Shan felt that his niece Qiao Yifei was a little abnormal, there was a knock on the door outside!

Qiao Shan opened the door and saw that it was Jiang Fan!

"Xiaofan, why don't you call in advance so that I can pick you up!"

"The driver assigned by leader No. 1 drove directly downstairs, and I came right up!"

"Come, come, please come in!"

At this time, Qiao Yifei saw Jiang Fan at the door, and her heartbeat suddenly accelerated.

She hurriedly sat down on the sofa dignifiedly, with her back straight, holding a book and pretending to read!

After Jiang Fan walked to the living room, Qiao Yifei gracefully put down the book and said to Jiang Fan!

"Brother Jiang Fan is here!"

"Um!"

Jiang Fan then responded, without taking another look at Qiao Yifei, and then followed Qiao Shan into the study!

Qiao Yifei was stunned on the spot.

this……

What is going on?

She once wondered if Jiang Fan hadn't seen her just now.

She actually wore a dress specially just to attract Jiang Fan!

Qiao Yifei took a look at her figure, and then picked up her mobile phone to take a picture of her exquisite facial features. She may not be confused by all living beings, but she is definitely an out-and-out beauty!

I remember when I wore this dress to a ceremony, I was definitely the focus of the venue.

Why is Jiang Fan not working!

Qiao Yifei really couldn’t figure it out!

She sat on the sofa and meditated hard for more than ten minutes, and finally suddenly remembered what Jiang Fan's girlfriend Chu Ruoxi was wearing!

She seemed to understand something!

It turns out that Jiang Fan wanted to be pure.

Qiao Yifei smiled brightly, returned to her room, and began to rummage through the boxes.

She turned her wardrobe upside down, and it was full of sexy and revealing clothes!

"Hey! Why don't you have any pure clothes?"

Qiao Yifei sighed helplessly.

She checked the time on her phone, and it was already half past twelve at night.

So, she opened her phone and made a call directly!

The phone rang for more than thirty seconds before the call was connected!

"Hello……"

A confused voice came.

"Xiaoyu, get up quickly and help Jianghu!"

Qiao Yifei lowered her voice and said to Xia Xiaoyu!

"Sister, what's going on? You don't even know what time it is!"

“A hot pot meal!”

When Xia Xiaoyu heard Qiao Yifei say this, she suddenly sobered up a lot!

This is her favorite food!

"Tell me, what's the matter?"

"Send me some pure clothes!"

"Pure clothes? Sister, it's not what you're wearing, right? Why are you having sex in the middle of the night?"

"Oh! Don't worry about it. The light blue dress you bought when we were together at the Guomao Mall last time. Send it to me quickly!"

"This is my favorite dress!"

Xia Xiaoyu also said with some reluctance!

"Two hot pot meals!" Qiao Yifei said cheerfully!

"I don't want to eat hot pot, I mainly care about our sisterhood."

Xia Xiaoyu said with a smile!

"Okay, stop talking nonsense, I'm at Huaqing University, speed!"

"Don't worry, we will definitely arrive within 15 minutes!"

Qiao Yifei hung up the phone and couldn't help but raise the corners of her mouth!

She believes that with this pure dress, she can definitely attract Jiang Fan!

She then remembered that Jiang Fan had a girlfriend, and it seemed a bit unethical for her to do so.

However, she then gave up the idea.

"Jiang Fan and Chu Ruoxi are just in love, not married! This is normal competition and has nothing to do with morality!"

Qiao Yifei comforted herself!

Then she opened her door and quietly walked to the door of the study!

At this time, the study door was ajar, and she pricked up her ears to eavesdrop on the conversation between Jiang Fan and her uncle!

"Photovoltaic materials can generate electric current because of the voltaic effect of light, which is if light shines on the solar cell and the light is absorbed at the interface layer...

Photons with sufficient energy can excite electrons from covalent bonds in p-type and n-type silicon, resulting in the generation of electron-hole pairs..."

Jiang Fa talked eloquently and explained photovoltaic materials to Qiao Shan.

Qiao Shan listened carefully and from time to time pointed out some things he didn't understand!

"Xiaofan, the photoelectric conversion rate of the monocrystalline silicon you are talking about, Blue Star's most advanced countries, Meili and D, is between 12% and 15%, but the photoelectric conversion rate of the monocrystalline silicon we study is only 10%, regardless of whether we

No matter how much I change, I can't make a breakthrough. What's the problem?"

After Qiao Shan finished speaking, he took out the information from his handbag and handed it to Jiang Fan!

Jiang Fan took it and studied it for a while, then said!

"Uncle Qiao, there is a problem with the photovoltaic material monocrystalline silicon you are studying..."

Qiao Yifei outside the door felt relieved when she saw the two people talking animatedly.

It seems that Jiang Fan won't be able to leave for a while.

Qiao Yifei tiptoed back to her room, and then sent a message to Xia Xiaoyu asking where she was!

In about ten minutes!

Xia Xiaoyu arrived downstairs at Qiao Yifei's house, and Qiao Yifei was already waiting downstairs!

"Sister, what style are you wearing?"

Xia Xiaoyu looked at Qiao Yifei in confusion, and saw that Qiao Yifei was wearing a noble dress underneath, but she was wearing a furry pajamas outside!

"Don't worry so much! Are your clothes worn?"

"Give!"

Xia Xiaoyu handed Qiao Yifei a handbag, which contained her light blue skirt!

Qiao Yifei took a look and gave Xia Xiaoyu a thumbs up!

"terrific!"

"A must!"

Qiao Yifei then turned around and went upstairs, and Xia Xiaoyu followed her!

"What are you doing?"

Qiao Yifei said to Xia Xiaoyu who was following behind her.

"Sleep with you!"

Xia Xiaoyu said.

"Not today!" Qiao Yifei said!

"It's so late, you won't let me go back, will you?"

Xia Xiaoyu said aggrievedly.

"I'll give you the taxi fare. Be good and go back by yourself!"
