From child prodigy to chief scientist

Chapter 125 doesn't seem to be the wrong address.

After successfully holding a celebration for their child's graduation, Xu Xiao and her family of three returned to Yanjing.

Xu Xiao then received a notification from Fei Ran, saying that the national math competition team had decided to award each member a bonus of 3 yuan in recognition of their outstanding performance at the IMO.

Xu Xiao also received a special award at this year's IM0, in consideration of his enormous contributions to the team.

On top of what he already received, the team gave him an extra 3 yuan.

This is only the national team's bonus. In addition, the provincial and municipal governments and his alma mater also gave Xu Xiao bonuses of varying degrees.

In addition to the prize money he received for being admitted to Peking University through the math competition and for being the top scorer in the college entrance examination, Xu Xiao now has nearly 500,000 yuan in savings.

In 2026, a savings account of 500,000 yuan may be insignificant, perhaps only reaching the average level in some large cities.

But in 2005, such a deposit was quite considerable.

In this era, the national per capita disposable income was only about 10,000 yuan per year, and the per capita savings were only about 15,000 yuan.

By the age of twelve, Xu Xiao's savings already exceeded those of most people in the country.

Even within the Second Ring Road of Beijing, this amount of money could easily buy a house outright.

Xu Xiao had indeed considered whether to do it immediately, since according to the trajectory of his previous life, as long as he bought the house and left it, it could appreciate more than tenfold in value later.

"Small A"

However, considering that the process would indeed be quite lengthy, Xu Xiao preferred to keep the several hundred thousand yuan as working capital first, so that it would be more convenient for him to use the money in the future.

Once you have enough money, it's not too late to buy a few houses and let them appreciate in value.

"Now, it's time to buy a laptop."

Xu Xiao had considered this before, but he hadn't chosen to buy one because current laptops were simply too expensive.

However, he now has plenty of money, and buying a laptop will make it more convenient for him to look up information and write papers in the future.

Xu Xiao glanced at the current laptop market. Although there were quite a few machines priced at a few thousand yuan, their configurations were really not good enough and couldn't even compare to the desktop computers in the computer room.

After comparing several options, Xu Xiao ultimately decided to spend a hefty sum of over 16,000 yuan to buy a ThinkPad T43P.

The Pentium M processor paired with the ATI FireGL V3200 dedicated graphics card was quite powerful back then.

Two 512MB RAM sticks and a 100GB hard drive provide ample space for program execution and storage.

While it certainly can't compare to a top-of-the-line desktop computer, it surpasses most desktop computers.

However, laptops of that era were rather bulky, with the entire computer weighing five or six kilograms, making them not particularly convenient to carry.

In fact, Xu Xiao had also considered buying the integrated graphics version. Removing the dedicated graphics card would make it much lighter, and many functions only require CPU power, so the integrated graphics would be sufficient.

However, considering that I may need to do graphics card-intensive tasks like 3D modeling in the future, having a dedicated graphics card is a good precaution.

When it was time to register for the new semester, Xu Lang and Yu Guilan prepared to accompany Xu Xiao to her new dormitory.

This time, none of them felt like they were truly starting university.

After all, Xu Xiao had already come to Yenching University to audit classes several months in advance, and Xu Lang and Yu Guilan were already staff members of Yenching University. They didn't even need to take a car to take Xu Xiao to register; it was just a matter of walking a few steps.

Xu Xiao's new dormitory is room 202 in building 46 of Yanda University. Since some of his things were previously left in Dong Yi's dormitory, the three of them went to the doctoral apartment to pick them up first.

Upon learning that Xu Xiao was going to register for the new dormitory, Dong Yi made a special trip back to the dormitory to help Xu Xiao move her things over.

Hello, Uncle and Aunt.

"Hello Dr. Dong. Xu Xiao used to live with you; did she cause you any trouble?"

"No, no, Xu Xiao is such a wonderful kid. I have to thank him for his help; without him, I wouldn't be able to finish my project at all."

Through Dong Yi's explanation, Xu Lang and Yu Guilan learned that Xu Xiao had actually participated in Dong Yi's doctoral research project and made significant contributions during this period.

No matter how confident they were in their son, they could never believe that Xu Xiao had already reached the level of participating in a doctoral project.

While they were packing, Dong Yi pulled out a box of his books, carried it over to Xu Xiao, and said, "Xu Xiao, these are some textbooks and materials I used from my undergraduate to doctoral studies. If you need them, I can help you move them to your new dorm room."

Dong Yi has basically confirmed that he will graduate this year, so he will not need these materials.

Hearing Dong Yi say this, Xu Xiao naturally couldn't be more eager to obtain these materials.

Compared to brand-new textbooks, textbooks that have been used by others are often more valuable, as they contain additional notes and annotations.

Dong Yi is among the top-ranked doctoral students in the Mathematics Department of Yenching University, so the materials he uses naturally have a higher value.

Moreover, some of these are foreign language professional books that are out of print and may not be available to buy now even if you want to.

Receiving a newbie gift pack from a senior PhD student who's already at max level before the semester even starts is a privilege not everyone gets.

"Thank you, Senior Brother Dong. I will cherish these materials."

After packing their things, everyone helped Xu Xiao move them to the new dormitory.

"Building 46, Room 202 — this should be it."

Upon arriving at the location, Xu Lang knocked on the door and went inside, only to be surprised to find that there was only a long-haired student inside.

"Excuse me, it seems we've gone to the wrong place."

Xu Lang instinctively felt that this was a girl, so he quickly closed the door and left.

"This looks like a girls' dormitory; there's only one girl inside."

"That's impossible, Uncle. Building 46 is entirely male dormitories; there are no female dormitories at all."

Dong Yi was quite familiar with the situation here. Upon hearing this, Xu Lang was also somewhat puzzled. He looked at the room number again and confirmed that this was indeed dormitory 202.

Xu Lang could only guess that the girl might be Xu Xiao's roommate's girlfriend or something, so he pushed the door open again and went inside.

"Excuse me—is this room 202?"

"Yes, isn't it written outside the door?"

Upon hearing the man's voice, Xu Lang was startled, realizing he had made a blunder.

Because this person's voice was very masculine, it was clear that he was not a girl at all, but just a boy with long hair.

Upon seeing the prominent Adam's apple in his throat, Xu Lang was even more certain of the other person's gender.

Xu Xiao was somewhat helpless; it seemed that Xu Lang had mistaken the other person for a girl.

However, this is somewhat understandable, since the other person is quite pretty and has long hair, so if you don't look closely, it's easy to mistake them for a girl.
