High Ridge Flower Rescue Project

"Leibniz proposed the term topology in 1679. The proposal and proof of the Poincaré conjecture, one of the famous millennium problems, has been applied to the relevant theories of topology..."

The gray-haired professor on the podium quickly uttered a series of nouns, and after a brief introduction to the history of the subject, he went straight to the topic.

There was no sound in the huge classroom, and everyone looked blankly or frowning at the blackboard in front of the classroom.

The Mathematics Department of University A is one of the top majors in the world. Every year, most of the people who take this major either come from competitions or recruit students independently. Few of them rely directly on the college entrance examination.

This year, Lu Huizhou is the only one in the mathematics department.

Lu Huizhou also learned a lot of mathematics knowledge by himself before, but the information he had access to was too little, and most of them were learned by himself.

It wasn't until after entering university that Lu Huizhou really had the conditions to learn mathematics.

The way of teaching in college is completely different from that in high school.

In high school, the teacher breaks up every piece of knowledge and teaches you step by step, for fear that you will not be able to learn it.

But when it comes to universities, especially A Dashu College where there are many scholars from all walks of life, the teachers will no longer accommodate the students.

Learning is your own business, you can understand as much as you can, and the same topic will not be repeated a second time.

If you don't understand or do it, that's your own problem.

The professor on the stage seemed to be a little excited about what he said, and he even demonstrated it on the blackboard.

All kinds of mathematical symbols quickly filled half the blackboard.

"...If we change the operation to take the closure or take the interior, we only need to discuss two or three special cases to prove it. Among them, we can mention a Kuratowski monoid The concept of...Interested students can search for related papers after class to understand by themselves."

Finally, near the end, the professor wrote a topic on the blackboard again, and said with a smile: "This is an after-school exercise, and it will be sent to my mailbox after it is done."

Still no one spoke below.

The professor seemed to be used to such a classroom atmosphere, and he didn't care at all. After putting down the chalk, he walked away slowly.

After the professor left, the other students left the classroom in twos and threes, carrying bags and books one by one.

This kind of big class is several sessions together, and one class lasts for three or four hours.

It is this kind of extremely high-density knowledge input, even if the students here are all kinds of academic masters and academic gods in middle school, it is inevitable that they will feel dizzy at this time.

After Lu Huizhou and the others had almost left, they packed up the draft paper of their calculations and prepared to leave.

The problem left by the professor is not very difficult, but it is not easy to solve it.

Lu Huizhou already had a preliminary idea in his mind, and now he was a little anxious to write it down.

Lu Huizhou walked towards the library with his bag on his back.

Just when he was about to return to the library, a boy with a spiky hair came over and blocked his way.

"I heard that you are working at 'Yang' now?"

When Lu Huizhou saw this man, his expression turned cold. He didn't reply, but just ignored the boy and was about to walk forward.

"Hey! I said Lu Huizhou, don't be shameless!" The hedgehog-haired boy stretched out his arm to block it, "When you rejected me before, I thought you were so noble, why," the boy's voice was low Come down, with a little ambiguity and ridicule: "I heard that you accompanied a guest for a night yesterday?"

The hedgehog-haired boy is called Wang Cheng, and he is also the rich second generation who chased Lu Huizhou before but was rejected.

Lu Huizhou has been unable to find a job because he has been making trouble.

He is also a frequent visitor to that bar, so after knowing that Lu Huizhou went to work there, he knew something easily.

I just don't know who the guest was last night.

Lu Huizhou looked at him blankly, still thinking about the math problem in his mind, looking a little frightened.

There are many students coming and going in the library.

But Wang Cheng is a celebrity in University A. He is notoriously stingy, cats and dogs hate him, but his family is rich and powerful. I heard that in order to be able to enter University A, the family donated two teaching buildings. Just came in.

Such a person didn't know why he got involved with Lu Huizhou.

Although the onlookers couldn't understand Wang Cheng's bullying, they didn't have a deep friendship with Lu Huizhou, so naturally they didn't want to get themselves into trouble.

Seeing that Lu Huizhou remained silent, Wang Cheng said, "You were pretty good at talking before? Why? You dare not admit it, do you?"

Wang Cheng slowly approached Lu Huizhou. Of course, he didn't intend to do anything in public, he just wanted to disgust Lu Huizhou.

A hand suddenly stretched out from the side and pushed Wang Cheng.

Wang Cheng was caught off guard, and suddenly staggered a few steps to the side.

He didn't expect that someone would dare to meddle in other people's business, so he looked over in shock,

"You look for......"

But he got stuck at the last word, and the fierce expression on his face was too late to retract. He looked like he wanted to laugh but couldn't make it out, it was very funny.

Xi Hua arrived here at some point, frowning and said coldly, "What are you looking for?"

Wang Cheng finally squeezed a smile out of his face: "Young Master Luo."

Xi Hua flicked his wrist, "Your father took so much effort to send you in, not for you to bully your classmates."

Wang Cheng was disdainful in his heart, and there was something in his tone, "Young Master Luo, you may have misunderstood. Classmate Lu and I were just joking around."

But he still didn't dare to offend the Luo family, it didn't matter how much he messed around, but Wang Cheng was clear about who could be messed with and who couldn't be messed with.

If I had an unpleasant quarrel with Young Master Luo over such a small matter today, I probably wouldn't be able to pass the test at home.

At the same time, Wang Cheng couldn't help feeling that today was a bad day. He knew that the Luo family also went to school in University A, but he had never met him since the beginning of school.

What a coincidence, why did I run into it just now?

And he doesn't even know, is the Luo family so nosy?

Xi Hua didn't expect Wang Cheng to change his past with just one or two words, but he still gave a few words of warning.

After Wang Cheng left, Lu Huizhou finally figured out the topic in his mind.

Xi Hua looked at Lu Huizhou's stunned look, and suddenly couldn't help but tapped his forehead.

"Hey, what's the matter with you? Are you scared?"

A few traces of other emotions finally appeared on Lu Huizhou's calm face.

His eyes widened slightly, as if a little surprised, he touched his forehead, suppressed the strange feeling in his heart, and replied: "No...I was thinking about a question just now."

After a pause, Lu Huizhou whispered, "Thank you."

Although he knew that this was nothing to Xi Hua, but it helped him after all.

Xi Hua looked at Lu Huizhou worriedly, "Why does your face feel a little wrong?"

Lu Huizhou felt that his heart was beating a little fast now, and his palms began to break out in cold sweat. When his eyes went dark, his whole body went limp.

Xi Hua was taken aback, and quickly supported Lu Huizhou, "Lu Huizhou, what's wrong with you?"

At the same time, he hurriedly asked the system: "What's the situation with Lu Huizhou now?"Why did you faint all of a sudden? '

It took two seconds for the system to reply: "It should be hypoglycemia, just eat something." '

Xi Hua helped Lu Huizhou sit down on the chair next to him, let him lean on his body, and then quickly started to rummage through his pockets.

He began to rejoice that he got up too late this morning, so he grabbed a few pieces of chocolate and put them in his pocket.

After tearing off the package in twos and twos, Xi Hua quickly stuffed the chocolate into Lu Huizhou's mouth.

His finger touched Lu Huizhou's lips inadvertently, but Xi Hua didn't care, he just comforted: "Hurry up, eat something and you'll be fine."

Lu Huizhou felt that his body couldn't exert himself at all, his head was dizzy, he was flustered and sweating coldly, and his whole body seemed to have a feeling of dying.

Until a sweet and bitter taste of chocolate hits his taste buds.

The blurred world in front of my eyes seemed to slowly become clear again.

There was a very fresh breath coming from the tip of the nose, the taste was a bit bitter, and it seemed to have a little sweetness.

For a moment, Lu Huizhou couldn't tell whether the smell was coming from the people around him or the chocolate in his own mouth.

The heartbeat that had gradually calmed down seemed to be accelerating again.

Lu Huizhou clenched his hand involuntarily, and said hoarsely, "Thank you."

It seemed that every time he met Xi Hua, he was causing trouble for him.

"Are you feeling better now?"

Xi Hua frowned and looked at each other worriedly.

At this moment, Lu Huizhou felt that his strength had begun to come back slowly, so he sat up straight with support, but his voice still sounded a little weak: "I'm fine."

"Lu Huizhou." Xi Hua called the other party's name, "Did you not eat at noon?"

Seeing that the other party didn't speak, Xi Hua suddenly became ill, "What about the morning? You don't know how to eat breakfast, do you?"

He should have gotten a lot of commission from the wine last night?Why can't you even afford to eat? !

Xi Hua wanted to shake Lu Huizhou's head to see what was inside.

Don't you know what your body looks like?

"...have breakfast."

Lu Huizhou didn't know why, but when he heard the other party's questioning, he felt an inexplicable guilty conscience.

It's like, I did something wrong.

Xi Hua looked at Lu Huizhou and suddenly sighed.

He picked up Lu Huizhou's backpack and carried it on his body, stood up and stretched out his hand towards him,

"Can you stand up now?"

Lu Huizhou looked at the hand in front of his eyes and obviously hesitated.

But in the end, he lowered his eyes and put his hands on it, using his strength to stand up.

The opponent's hand was slightly smaller than his own, with healthy and beautiful light pink on the fingertips.

Lu Huizhou felt that his hand did not dare to move when it touched the other party, and his mind went blank.

Xi Hua didn't even react when he said to take him to dinner.

It wasn't until he was dragged by the other party for a few steps that Lu Huizhou's brain started to work again.

"Student Luo, let me go first."

"You can call me by my name directly," Xi Hua held the hand of the task subject, feeling like a worried old woman. "My name is Xihua."

Lu Huizhou's heartbeat seemed to miss a beat, and a very strange feeling came to his heart again.

He pressed the tip of his tongue, deliberating for a long time, and finally pronounced these two words slowly.

"Xi Hua."
