Chapter 91 Difficulties in Cracking the Code

It was common knowledge in the school that Xu Yuan liked to hand in his exam papers early.

But it was a bit shocking that as a freshman taking the senior exam and having almost no professional courses, he still submitted the paper so early.

I'm afraid you won't be able to study the topic thoroughly with such a short period of time?

When the invigilator suddenly heard someone hand in the paper, he didn't react for a moment and realized that the person who handed in the paper was Xu Yuan.

I couldn't help but ask subconsciously.

"Hand in the paper now?"

"Are you sure you've done it all?"

"of course."

Xu Yuan nodded with certainty: "This year's test paper is relatively simple, and it only tests basic knowledge."

He was indeed right in saying this.

After finishing the entire math analysis test, I felt that the questions were simpler than those in Jimidovich's exercise book, and I had no interest at all in the process of doing the questions.

So I finished the questions as quickly as possible.

However, when these words reached the ears of other candidates around, the situation immediately became completely different.

Everyone looked down at their test papers, and the urge to complain suddenly grew stronger in their hearts.

Is this year's test paper easy?
I left three multiple-choice questions blank, and you tell me that's very basic?

Before I even finished filling in the blanks, others had already handed in their papers. This is the gap between me and the god of study.

Who just said that Xu Shen couldn't get full marks?

Thoughts kept flashing through my mind, and I had a new understanding of Xu Yuan's mathematical level.

Especially those who previously thought that Xu Yuan could not get full marks were extremely dumbfounded at this moment.

Being able to finish and hand in the test paper so quickly must mean that one has enough confidence in one's own abilities.

Mathematics is a subject that is different from liberal arts. If you are so confident, there is no chance of making mistakes and losing points.

That means you won't get a perfect score.

It was not until this time that they realized that Xu Yuan was not the math genius they thought he was.

Being in Qinghua University, the most famous university in the country, so-called child prodigies are not uncommon. After seeing them so many times, we have become accustomed to the existence of these geniuses.

But you have to know that there are differences between geniuses.

How can one know the strength of an extraordinary genius with one's understanding of ordinary geniuses?

Just when everyone in the examination room was getting nervous, the invigilator on the stage finally reacted.

He quickly walked to the stage and collected Xu Yuan's test paper.

"You can leave the examination room after handing in your paper, and then just take the next exam on time."

"Good teacher."

Xu Yuan handed the test paper to the other party and responded, then took his stationery and walked out.

Although the exam has not started for long yet, Xu Yuan does not need to go somewhere else to wait alone.

Zhang Jundong, who was sitting in the back row, watched Xu Yuan until his back disappeared from his sight.

He himself was not surprised at this scene at all, because this was exactly the Xu Yuan he knew.

A junior who inspires me every time I see him.

If Xu Yuan had waited until the last minute to hand in his paper, he would have found it incredible.

"Now you can understand my feelings, right? This is not a genius at all, he is simply a demon in the field of mathematics."

Zhang Jundong looked at the test paper where he had just finished filling in the blanks and sighed in his heart. After a while, he adjusted his mentality and continued to answer the next questions.

For Xu Yuan, he would actually prefer to have all the test papers for all subjects sent out together.

This way he can finish it in one go.

But in order to avoid adding to the workload of the college and the invigilators, he had no choice but to take the exam as scheduled.

After handing in the paper, I went to the nearby discussion room to do my own things, so I didn't waste any time.

that's it.

For the next few professional exams, Xu Yuan chose to finish them as quickly as possible and hand them in early.

At first, other people were very excited, but later they became numb.

When I heard Xu Yuan shouting to hand in the papers, I was too lazy to raise my head.

With the end of the final exams, college students can finally breathe a sigh of relief.

The smile returned to his face.

After all, going home to celebrate the New Year during the winter vacation is the most exciting thing.

However, some juniors or seniors did not choose to go home because of their future work considerations.

Instead, I looked for winter vacation job opportunities in Yanjing or surrounding cities.

Even if you earn a few hundred dollars, it can at least alleviate the pressure on your family to support your schooling.

The important thing is that not everyone is like Xu Yuan, who, in addition to being exempted from tuition and living expenses and receiving a full scholarship, can also make money easily at school.

"See you after the holidays."

"I will pack a suitcase of New Year's goods from my hometown for my brothers."

At this moment in the boys' dormitory, Li Zhenya was packing his things. He had already started painting the pie before he even returned home.

Perhaps because they performed well in the final exam, everyone seemed very happy.

There was only joy on his face at being able to go home.

"The roast chicken I have is delicious. I'll bring you two when school starts." Wang Haitao, who was standing on the bed with his back bent, echoed Li Zhenya's words.

Upon hearing this, Xu Yuan smiled and agreed.

"Then I'll be in luck."

Soon, several people packed up their things and pulled their luggage to prepare to go to the station.

Since Liu Yang's home was in Yanjing and there was no need to rush, he went to the station first to help with the luggage.

Xu Yuan did not book a train ticket in advance. He only bought a ticket to Luyang at the window after arriving at Yanjing Station.

It is not yet the peak of the Spring Festival travel rush, and there are many trains going to their provincial capital, so there is no need to worry about not being able to buy tickets.

The reason why he did not return to Pingzhou City directly was because his parents were still looking after a store in the provincial capital.

Instead of going home alone, it would be better to go back with my parents and sister.

Since Xu Yuan and Li Zhenya had different departure times, they separated soon after, and Xu Yuan also successfully boarded the train to the provincial capital.

……

Compared to the rural area in my hometown with inconvenient transportation, there is no need to worry too much about traveling in the provincial capital.

After Xu Yuan arrived safely at his destination after taking an overnight train, he did not call his parents to pick him up. Instead, he took a bus directly to where his family's store was located.

It's a surprise for my parents.

Their store opened in the second half of the year after a simple renovation. In addition to selling cigarettes and alcohol, it also sells a variety of snacks and gifts. It can be called a small supermarket that is convenient for residents in the surrounding communities.

Plus the area and layout are pretty good, and my parents can just stay in there at night.

Maybe there won't be much business in the early stage, but when nearby properties start to be delivered and people move in next year, the situation will get better.

Xu Yuan arrived at the door of the tobacco shop, looked inside, and immediately found Ms. Liang Yanli sitting behind the glass counter.

So he tiptoed over and spoke in the tone of a guest.

"boss."

"What kind of wine do you have here?"

When Liang Yanli heard someone coming in, she quickly raised her head and was about to introduce them, but what she saw was a face that couldn't be more familiar.

It took a moment of hesitation before he reacted quickly.

"Xiao Yuan."

"Are you back from vacation?"

"Why don't you call your dad in advance so we can pick you up at the station."

Seeing that it was her son who came back, Liang Yanli quickly got up and came out from the counter. While helping with the luggage, she did not forget to call people inside.

"Jianguo, your son is back, come here quickly."

Xu Jianguo, who was sorting goods at the back of the warehouse, heard his wife's shout and hurriedly put down his work.

He looked at Xu Yuan and said the same thing.

"I've been waiting to pick you up at the station these days, thinking that you'll be on vacation soon."

"I didn't expect you to come back on your own."

"There's not much luggage, so there's no need for you to go and pick it up." Xu Yuan took his luggage to the back and said with a smile on his face.

At this time, Liang Yanli poured a cup of hot water, handed it to her son and talked about family matters.

"Have a cup of tea to warm yourself up first."

"It just so happens that your sister will be back tomorrow, so we can close the store early and go back to our hometown to celebrate the New Year."

Upon hearing this, Xu Yuan naturally agreed readily. Since there were not many customers coming to the shop now, it would be better to close the shop early and go home for the New Year.

Xu Yuan then strolled around the store and found that there were not many things on the shelves. However, considering that his family's current liquidity was limited and the number of customers was relatively small, this was normal.

But what surprised him most was that Ms. Liang Yanli also brought his Olympic gold medal here.

There was also a framed newspaper hanging on the wall, and judging from the content, it should have been from when he was attending an academic conference on number theory.

Thinking that he had already used his reputation as the top scholar to endorse the real estate here, having these things now would be able to attract quite a few customers in the initial stage.

It's a nice gimmick.

Even as his popularity grows in the future, the number of people visiting his store will surely increase.

He was originally worried that his parents had no experience in running a store and would feel bad about losing money.

Now seeing these, I feel much more relieved.

The next day he went to the Normal University in person to pick up his sister. He originally wanted to visit Yang Bin at the Industrial University next door, but he was told that the winter vacation had already passed there.

After the family was reunited, they did not stay in the provincial capital for too long and took a bus back to their hometown in Guyuan County the next day.

It happened to be the Little New Year, and every household began to prepare New Year's goods.

Xu Yuan is now enjoying the best treatment at home. Not only does his parents not let him do any work, but even his sister Xu Ying's temper has become much softer.

With nothing to do, Xu Yuan had to stay in the room and continue studying how to crack the MD5 password algorithm.

Only after he really started to solve the problem did he feel the difficulty. Even though Wang Xiaoyun's team had made some progress, he only needed to follow the progress and help the entire team to derive a large number of equations.

But faced with hundreds of complex equations, his efficiency in doing it manually is no less than that of computer automation.

However, it is still a very complicated task to deal with the contradictions between the equations.

Of course, facing such difficulties, he was not discouraged, but became even more excited.

He was even eager to overcome difficulties and win, which was why he had previously agreed to Professor Wang Xiaoyun's participation in this project.

As time went by and New Year's Eve approached, he gradually adapted to the rhythm of deriving the equations, and his speed and efficiency became faster and faster.
