Xue Xi was stunned when she saw the scene inside.

The office door and windows were closed and filled with the smell of ink and paper. It was stuffy, as though there had been no ventilation for a few days. Moreover, the light was very dim. It was clearly daytime, but the curtains were drawn and the lights were on. It gave off a strange feeling.

Feng Xingshen had his hands behind his back as he stood in front of the blackboard. He stared at the rows of equations written on it and paced back and forth. As he walked, he mumbled something as though he was possessed.

Zhou Hong was stunned and said, Teacher?

Feng Xingshen ignored him and continued staring at the blackboard. Even though his body was moving, his eyes were not moving. He ignored Zhou Hongs words as though he did not hear them at all.

Zhou Hong panicked and looked at Ji Silin, asking, Whats wrong with the teacher?

Ji Silin sighed. He has fallen into his own world. If he doesnt solve these problems, he wont be able to escape.

Zhou Hong was stunned. What what should we do?

Can academic researchers really reach this stage in the end?

So crazy?

Xue Xi looked at Feng Xingshen and suddenly thought of her maternal grandfather, Ye Lai.

Ye Lai was a chemistry professor and was also crazy now. Could it be

She looked at Ji Silin. Brother Silin, what will happen if the teacher cant come out?

Ji Silin was silent for a moment before sighing. Insanity.

Indeed!

Xue Xi could only look at the blackboard. She had never ventured on this mathematics knowledge point before. After seeing it, she realized how profound it was.

When she entered university, she only wanted to learn more basic sciences, but now, she realized that the mathematics field could be divided into several research directions.

Many people only focused on one direction and would never reach the top in their entire lives.

Xue Xi held her breath and stared at the equations.

At this moment, Ji Silin suddenly shouted, Elder Feng!

Perhaps because Feng Xingshen had not rested for a long time, his body swayed. Xue Xi immediately reached out to support him and softly shouted, Teacher!

The curtains were suddenly blown open by the wind. A light shone in and landed on the two of them.

Perhaps it was Zhou Hongs illusion, but he felt that the action of Sister Xi supporting the teacher was so sacred at this moment, as though it was a legacy

Moreover, there was no wind in the room. How could the curtains be blown open?

Just as Zhou Hong was feeling perplexed, Xue Xi helped Feng Xingshen sit down on the sofa. Just as she was about to let go, she realized that Feng Xingshen was still grabbing her arm tightly. His closed eyes suddenly opened. Sister Xi?

He looked around in confusion. Whats wrong with me?

Xue Xis expression was solemn. Teacher, you need to rest.

Rest.

Feng Xingshen smiled bitterly and looked at the blackboard. If I cant solve this question, I wont rest.

Just as he said this, he heard Xue Xi say, Teacher, let me.

Feng Xingshen was stunned.

Zhou Hong was also stunned.

Only Ji Silin was standing behind them. The light shone on his glasses and reflected a white light.

Feng Xingshen quickly reacted. Sister Xi, youve never learned the relevant knowledge. Itll be slow going for you. Let me do it

Zhou Hong also nodded. Junior, this topic is relatively unpopular. Very 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 and turned to look at the blackboard.

Just now, when she first saw the equations on the blackboard, she did not understand them. She did not understand the meaning of these lines, but as someone who was too good at mathematics, when she saw those symbols, her mind already became filled with them. The moment she held Feng Xingshen, she felt as though a flash of inspiration had appeared, making her suddenly understand the meaning of those equations.

It was very simple.

She picked up the chalk and started calculating on the blackboard.

Swoosh swoosh swoosh

The entire office suddenly fell silent. It was filled with the sound of Xue Xi writing the solutions. The sound of the chalk rubbing against the blackboard was the best music that Feng Xingshen had ever heard.

He stared at the blackboard and seemed to have suddenly understood something. In the end, he looked at Xue Xi and then at his hand that was holding Xue Xis.

Then, he suddenly smiled.

Half an hour later.

Zhou Hong stared blankly at the densely packed lines on the blackboard. Since theres no space left to write on this blackboard, he took out another one. The entire room became filled with blackboards, and she had also filled them up.

Sister Xi had once again solved such a world-class problem!

Zhou Hong looked at Xue Xi in disbelief and could not wrap his head around it. What kind of genius was this?

After writing the last number, Xue Xi threw down the chalk and took out a wet tissue to wipe her hands. She quietly turned around and looked at Feng Xingshen before slowly saying, Teacher, are there any more questions?

Feng Xingshen seemed to have been relieved. He sat on the sofa and said in a daze, No.

In the future, there might still be many difficult and complicated problems, but now, at least at this moment, the topic that he wanted to study his whole life had been solved.

He did not know when the curtains were drawn. The sunlight shone in and shone on Feng Xingshen. He felt warm.

The red-haired girl said, Teacher, then you should eat and sleep.

Feng Xingshen smiled like a child and nodded. Aye! Eat! Sleep! I can rest well!

That night, Li Xuekai left the laboratory and arrived at the hotel where he had arranged to meet Grandpa Li.

Just as he entered the private room, he saw Grandpa Li sitting on the sofa with a dark expression. Beside him, Mr. Li was smiling ingratiatingly. I thought that since youre already here, we should meet.

Li Xuekai was stunned.

When Grandpa Li saw Li Xuekai, his expression finally improved. He waved at him. Xiao Kai, come here.

Li Xuekai nodded. Just as he was about to walk over, footsteps came from the door. He turned around and saw Li Xuelei walking in.

He was no longer as arrogant as he was in school. Wearing a white suit, he stood there like a dog and respectfully greeted, Hello, Grandpa!

Grandpa Lis face darkened. Just as he was about to speak, Mr. Li stood up and dragged Li Xuelei into the room. Dad, no matter what, this is your grandson! Even if you have something against his mother, you cant implicate the child, right?

Grandpa Li was stunned.

Mr. Li dragged Li Xuelei over. When he passed by Li Xuekais seat, he bumped into him and made him take a step back. Immediately, Mr. Li pressed Li Xueleis shoulders and made him sit beside Grandpa Li. Sit here and have a good chat with your grandfather!

Li Xuekai looked at that spot.

It should have been him sitting there. It was the seat that Grandpa had saved just now.

He lowered his eyes and said, Grandpa, since you still have other guests, Ill leave first.

Grandpa Li hurriedly said, Xiao Kai, I came here to see you. What other guests? Nothing

Just as he said this, he heard a bang. Mr. Li slammed the table and stood up. Li Xuekai, what do you mean? You dont want your grandfather to acknowledge Li Xuelei? Let me tell you, this is your brother. You must accept it!

Li Xuekai frowned and was about to say something when Li Xuelei smiled awkwardly. He took out a gift and passed it to Grandpa Li. Grandpa, I heard that today is your birthday. This is my gift to you. If I am not welcomed, Ill leave first, lest I affect your mood.

Birthday

Li Xuekai paused.

It turned out that today was his grandfathers birthday. He was busy with scientific research, and every day, his days were reversed, making him muddle-headed.

He looked at Elder Li. Grandpa, Im sorry. I forgot that its your birthday today.

Grandpa Li said, Xiao Kai, its fine. What birthday? Im just having a meal with you.

Lets have a meal together

Li Xuekai could no longer move.

Mr. Li also said, Li Xuekai, your grandfather is already so old. In order to accommodate you, he especially rushed to the capital. If you throw a tantrum and delay your grandfathers birthday banquet tonight, you will be unfilial!

Li Xuekai clenched his jaw.

Today was his grandfathers birthday. No one wanted to make the scene too ugly. Hence, he dared to bring Li Xuelei over.

Li Xuekai lowered his eyes and sat down.

The four of them sat down around the dining table. Grandpa Li looked at Li Xuekai and said, Xiao Kai, is the project youve been researching quite tiring? Why do you look so pale and skinny?

Just as Li Xuekai was about to speak, Li Xuelei said, Yes, they often work overtime for their project. Sometimes, when we are done with our project for the day, we can even see them working overtime on theirs. Its too tiring.

Just as Grandpa Li was about to speak, Mr. Li sneered. So what if hes tired? Theyve come up with a bunch of useless theories, and they cant be put into practice at all. I heard that you spent hundreds of millions on them!

Li Xuekai: The investments were all from Sister Xis pocket. It has nothing to do with us, right?

Mr. Li sneered. A girl really doesnt know anything. Just because shes pampered by her family, shes wasting money like this. Stay away from her in the future, lest you get led astray!

Li Xuekai: Even if Im led astray, I dont have hundreds of millions to squander.

His bank card had long been confiscated!

Mr. Li choked. Just as he was about to flare up, Grandpa Li flew into a rage. Such a delicious meal and it cant even stop your mouth! If you speak again, Ill chase you out!

Mr. Li immediately smiled ingratiatingly. Dad, let me introduce Xiao Lei to you. The project hes working on is about to succeed. Were also about to invest in its mass production, and our future profits will reach tens of millions. Although tens of millions is nothing to our family, this is his first project. Ive only invested a few million. Unlike some people who cant even get a single cent of the profits. Oh, thats not right. I heard that on your project, the team leaders salary is ten thousand yuan a month?

As Mr. Li was laughing mockingly, Li Xuelei said, Dad, dont say that. Xiao Kai has shares. I heard that the other team leaders have 0.5%, but Sister Xi likes Xiao Kai and gave him 1%. If their project is completed, it wont be a problem for them to earn five billion yuan a year. One percent is fifty million!

Mr. Li sneered. That is a huge piece of the pie. The prerequisite is that the project can be completed. However, if this project could be completed so easily by you college students, China would not have fallen behind the world for so many years!

At the same time.

In the laboratory, a huge piece of equipment had already been shipped over. There were only a few key parts left to be assembled. Yu Da put in the results that they had worked hard for half a month and pressed the switch.

Success!

Xue Xi:
