Xue Xi was stunned after seeing the scene inside.

The doors and windows in the office are closed, all smelling of paper and ink, stuffy, it seems that there has been no ventilation in a few days, and the light is very dark, it is obviously daytime, but the curtains are opened and the lights are turned on, giving people a strange feeling.

Feng Xing stood with his hands behind his back, standing in front of the blackboard, staring at the rows of chalk on the formulas, walking back and forth, as he walked, he was muttering something in his mouth, as if he had already been enchanted.

Zhou Hong was stunned and said, "Teacher?"

Feng Xingshen ignored him, but continued to stare at the blackboard, even though his body was moving, but his eyes were not moving. He even ignored Zhou Hong's words, as if he hadn't heard at all.

Zhou Hong was anxious, looked at Ji Silin, and asked, "What's wrong with teacher?"

Ji Silin sighed: "He has fallen into his own world. If he doesn't solve these problems, he will not escape."

Zhou Hong was stunned: "This, what can I do?"

Those who engage in academic research can really get to this point in the end?

So crazy?

Xue Xi looked at Feng Xingshen and didn't know what to do, but suddenly thought of grandfather Ye Lai.

Ye Lai is a professor of chemistry, and now he's crazy, shouldn't...

She looked at Ji Silin: "Brother Si Lin, what happens if the teacher can't come out?"

Ji Silin was silent for a moment, and finally sighed: "Go crazy."

it is as expected!

Xue Xi could only look at the blackboard. This knowledge of mathematics was something she had never touched before. After seeing it, she discovered the breadth and depth of knowledge.

When I was in college, I wanted to learn more basic sciences, but now I discovered that a mathematics department can be divided into several research directions.

Many people only move in one direction and never study the top for a lifetime.

Xue Xi held her mind and stared at the characters.

But at this moment, Ji Silin suddenly shouted: "Old Feng!"

Feng Xingshen may have not rested for a long time. His body shook. Xue Xi immediately stretched out his hand to support him and shouted in a low voice: "Teacher!"

The curtains were suddenly blown open by the wind, and a glimmer of light came in and fell on the two people.

I don’t know if it is Zhou Hong’s illusion. He feels that the action of sister Xi supporting the teacher is so sacred at this moment, like a kind of inheritance...

Besides, there is no wind in the room, so how could the curtains be blown open?

Just when Zhou Hong was wondering, Xue Xi helped Feng Shengshen to sit down on the sofa. When she wanted to let go, she found that Feng Shengshen was still holding her arm tightly, and his closed eyes opened suddenly. Sister Xi?"

He looked around blankly: "What's wrong with me?"

Xue Xi's expression was heavy: "Teacher, you need to rest."

"rest."

Feng Xingshen smiled bitterly, but looked at the blackboard again: "If I can't solve this problem, I won't rest."

As soon as these words fell, I heard Xue Xi speak: "Teacher, I will come."

Feng Xingshen was stunned.

Zhou Hong was also stunned.

Only Ji Silin stood behind a few people, and the light shone on his glasses, reflecting a white light.

Feng Xingshen reacted quickly: "Sister Xi, you haven't learned the relevant knowledge, it will be very slow, let me come..."

Zhou Hong also nodded: "School girl, this knowledge is relatively unpopular. Few people study this topic. I think you should advise the teacher to eat something and sleep for a while..."

Xue Xi ignored the two of them at all, she turned her head and looked at the blackboard.

Just now, when she first looked at the characters on the blackboard, she still didn't understand, and she didn't understand the meaning of these characters, but she was too good at mathematics. Seeing those symbols, she had already taken root in her mind. At the moment when she held Feng Xingshen, she felt like a flash of inspiration, which made her suddenly understand the meaning of those things.

It's simple.

She picked up the chalk and quickly calculated it on the blackboard.

"Swipe..."

The whole office suddenly quieted down. It was all Xue Xi's voice writing the topic, and the sound of chalk rubbing on the blackboard, Feng Shengshen had heard, the best movement in this life.

He stared at the blackboard, as if he had suddenly understood something, and finally looked at Xue Xi, and then looked again, just holding Xue Xi's hand by himself.

Then he suddenly smiled.

After half an hour.

Zhou Hong stared blankly at the densely packed characters on the blackboard. The blackboard could no longer be written, so he took out the blackboard again. The entire room was filled with blackboards, and she was filled with them.

This kind of world problem, something that the whole world could not study, was once again made by Sister Xi!

Zhou Hong looked at Xue Xi in disbelief. He just felt that his mind was a little overwhelming. What kind of genius is this man?

After writing the last number, Xue Xi dropped the chalk, took out a wet tissue and wiped the paper towel. She quietly turned back, looked at Feng Shengshen, and slowly said, "Teacher, are there any questions?"

Feng Xing seemed to be relieved, leaning on the sofa, he said blankly: "Nothing."

In the future, there may be many difficult and miscellaneous diseases, but now, at least for this moment, the subject he wants to study in his life is to study it.

The curtains were opened at some unknown time. The sunlight came in and shone on Feng Xingshen's body. He felt warm and warm.

And the girl with red hair said: "Teacher, then you should eat and sleep."

Feng Xingshen smiled like a child, he nodded: "Ah! Eat! Sleep! I can take a good rest!"

In the evening, Li Xuekai went out of the laboratory and went to the hotel he had agreed with Grandpa Li.

As soon as I entered the private room, I saw Grandpa Li sitting on the sofa with a very dark face. Next to him was Father Li who was pleased with a smile: "I thought, you are here, so see you all."

Li Xuekai was taken aback.

When Grandpa Li saw Li Xuekai, his face finally improved a lot, and he waved to him: "Xiaokai, come here."

Li Xuekai nodded, and when he was about to walk over, footsteps came from the door. When he turned his head, he saw Li Xuelei walking in.

He changed his appearance in school, dressed in a white suit, standing there like a dog, and said respectfully: "Hello Grandpa!"

Grandpa Li's face was even darker. When he was about to speak, Father Li stood up and dragged Li Xuekai into the door: "Dad, no matter what, this is your grandson! Even if you have opinions on his mother, you can't affect your children?"

Grandpa Li was slightly taken aback.

Father Li dragged Li Xuelei over, and when he passed Li Xuekai’s position, he bumped him slightly and made him take a step back. Immediately, Father Li pressed Li Xuelei’s shoulder and let him sit beside Grandpa Li: "You sit Here, talk to your grandfather!"

Li Xuekai looked at that position.

That should have been where he was sitting. It was the position where Grandpa took the photo.

He lowered his eyes and opened his mouth: "Grandpa, since you have other guests, then I will go first."

Grandpa Li hurriedly said: "Xiao Kai, I am here to meet you, what other guests, nothing..."

As soon as he finished saying this, he heard a "bang", Father Li patted the table and stood up: "Li Xuekai, what do you mean? You don't want your grandfather to recognize Li Xuelei? I tell you, this is your brother. , You must admit it!"

Li Xuekai frowned, and when he wanted to say something, Li Xuelei smiled awkwardly, took out a gift and handed it to Grandpa Li: "Grandpa, I heard that today is your birthday. This is my gift to you. If someone is not welcome I, then I will leave first, lest it affect your mood."

birthday……

Li Xuekai stopped in his tracks.

It turns out that today is Grandpa's birthday. He is busy with scientific research, and he spends days and nights upside down, making his life confused.

He looked at Old Li: "Grandpa, I'm sorry, I forgot that today is your birthday."

Grandpa Li spoke up: "Xiao Kai, it's okay, if you have a birthday or not, I just have a meal with you."

Have a meal together...

As Li Xuekai was about to leave, he couldn't move anymore.

Father Li also spoke: "Li Xuekai, your grandfather is so old, and he came to Kyoto to accommodate you. If you are making a temper and delaying your grandfather's birthday party tonight, you are not filial!"

Li Xuekai strained his chin.

Today is Grandpa's birthday, no one wants to make the scene too ugly, so he dare to bring Li Xuelei over.

Li Xuekai lowered his eyes and finally sat down.

A few people sat down around the dining table, and Grandpa Li looked at Li Xuekai and said, "Xiaokai, are you tired of the projects you recently studied? How come you look so ugly and thin!"

When Li Xuekai was about to speak, Li Xuelei spoke: "Yes, they often work overtime on projects. Sometimes our projects are over. When we leave, we can still see them working overtime on projects, which is too tired."

Grandpa Li was about to talk, and Father Li mocked: "How tired is it? I have made a bunch of useless theoretical knowledge, which can't be implemented at all. I heard that it has spent several hundred million in investment!"

Li Xuekai: "Sister Xi invested in all investments. Doesn't it matter to us?"

Father Li sneered: "A girl who really doesn't understand anything, relying on her family to spoil her, just spend money like this, stay away from her in the future, lest you be taken away!"

Li Xuekai: "...Even if I am taken away, I don't have hundreds of millions to spend."

His bank card has long been confiscated!

When Father Li choked, he was about to get angry, and Grandpa Li became angry: "Have a good meal, and I can't stop your mouth! If you talk any more, I will kick you out!"

Li's father pleased him with a smile now: "Dad, let me introduce Xiaolei to you. His project is about to be successful, and we are about to put into mass production. The future profit can reach tens of millions. Although tens of millions are good for our family. It’s not a big deal, but this is his first project. I only invested a few million. It’s not like some people, who don’t get a penny of profit. Oh, no, I heard that your project , The group leader’s salary is 10,000 yuan a month?"

When Father Li smiled so mockingly, Li Xuelei said, "Dad, don’t say that. Xiaokai holds shares. I heard that other team leaders are 0.5%, but sister Xi Fancy Xiaokai, and gave him one percent. If their project is completed, the annual income of 5 billion yuan will not be a problem, and one percent is 50 million yuan!"

Father Li sneered at the moment: "This is a big pie. The premise is that the project can be completed, but if this project can be completed by a few of you college students so easily, China will not be behind foreign countries for so many years!"

at the same time.

In the laboratory, the huge instruments had already been shipped, and only the last few key parts were assembled. Yu Da packed the results of a few months of hard work and pressed the switch.

That's it! !

[The update owed yesterday is out of order. I was still very uncomfortable, but felt that I couldn't stop for two days, so I got up and got up the code word. This chapter is a fat chapter with more than 3,000 words. I went to continue to spread it. . . Recently, my health was very bad, which caused my aunt to kill her half-life. She vomited twice last night, so she could write more or less~ Unless she can't get up, she won't break her. Saying so much is not Bo sympathetic, but just to explain the cause of the disease clearly, meme da. 】
