246: The bitter forest has a long history!

The next day.

Freshman registration officially ended, and Lin You followed the crowd to take photos and register his student information.

At noon, Su Wenwen, who had been "separated" from Du Zhaoyu for a whole day, finally squeezed her way over to find the two of them for lunch, holding onto her Yu Baobao the entire time without letting go.

"Don't think that just because you've started university, you can take all of my Yu Baobao for yourself. Yu Baobao and I need to have our own bestie time too."

On the surface, Lin You acted disdainful, but in reality, he gave Su Wenwen a huge mental thumbs-up. Inside Nandu University, there was Su Wenwen pestering Du Zhaoyu, and outside Nandu University, there was Wang Xinxin acting as a wingman tool...

One could only say that the future of the friendship between Lin You and his three good friends would rely entirely on the duplicated-character combinations to carry!

It was just that Wang Xinxin really wasn't living up to expectations; after so long, there hadn't been much progress with Su Wenwen. Although they could go out and hang out together, they were still at the "good friend" stage, with not much romantic tension.

It could only be said that, unlike Lin You, without the help of a system or memories from another timeline, relationships between ordinary people who took things seriously were mostly like this—a slow and steady stream.

That kind of relationship where people hook up in two or three days doesn't even count as love at first sight; it can only be considered the behavior of infatuated men and women controlled by hormones. Feelings that come quickly are also highly likely to leave quickly.

In the afternoon, Lin You and Du Zhaoyu shook off Su Wenwen, grabbed their backpacks, and went to the School of Mathematics Building to find Tang Zhenyi's "laboratory."

Although it was called a laboratory, its layout and functions were actually similar to an office. Graduate students in the School of Mathematics usually relied on their brains and pens to do research, and in most cases, they only needed a computer.

Lin You and Du Zhaoyu searched for a while before arriving at Tang Zhenyi's "laboratory."

As the only student of Professor Zheng who was still on campus at the time, Tang Zhenyi received good treatment in the School of Mathematics Building and was assigned a four-person laboratory.

However, the other three people were rarely on campus, so it was effectively for Tang Zhenyi's exclusive use.

"Junior brother, you rascal, have you really managed to snag the former school beauty of Ancheng No. 7 Middle School and the current school beauty of Nandu University?"

Tang Zhenyi invited the two inside while exclaiming to Du Zhaoyu.

Strictly speaking, this wasn't the first time Tang Zhenyi and Du Zhaoyu had met. Back at the commendation meeting at Ancheng No. 7 Middle School, Tang Zhenyi had seen Du Zhaoyu a few times.

But previously, Tang Zhenyi had only treated Du Zhaoyu as a passerby; this time, she treated Du Zhaoyu as her junior brother's girlfriend—so she was practically family.

Du Zhaoyu had outstanding looks and a great figure. After coming of age, her "high-mountain flower" aura made her stand out from the crowd. Most people would be amazed by her upon first meeting; perhaps she wasn't the most beautiful one, but she was the most stunning one when viewed as a whole.

Du Zhaoyu blushed and began to make polite conversation, while Lin You started to gloat with a grin.

"Senior sister, as the former number one of Ancheng No. 7 Middle School and the future number one of Nandu University, is it too much to ask for me to find the best-looking girlfriend?"

"Look at you showing off..."

Next, the three began to introduce themselves and chat. They had a lot in common—all were graduates of Ancheng No. 7 Middle School and had all come to Nandu University for their undergraduate studies—so it was easy to find common topics, especially since... Tang Zhenyi and Du Zhaoyu were both graduates of the Experimental Class.

The two girls hit it off immediately and began to "denounce" Lin You, the king of cramming from the ordinary class.

At Ancheng No. 7 Middle School, Du Zhaoyu had watched helplessly as Lin You's scores climbed all the way up, eventually surpassing her, ascending to the top of the grade, and finally becoming the top scholar...

Ever since Professor Zheng took Lin You on as his closing student, Tang Zhenyi had learned of Lin You's perverted learning speed through Professor Zheng over the past half year. In a recent test, she was even shown up by Lin You to her face, and was "forced" to start cramming twice as hard along with him...

They had all been "suffering" under Lin You for too long!

Lin You didn't mind being gossiped about by the two of them to his face; he wandered around the "laboratory," keeping an eye on the task status on the panel in his mind.

When Lin You had nothing to do, he took out the textbooks and exercise books from his backpack and started studying. By then, the two girls had become familiar enough to say, "Senior sister also knows quite a few people in the School of Physics; one of these days, I'll introduce some reliable teachers to you."

Lin You had long since realized that Tang Zhenyi was definitely a woman of action. He spread out his exercise book, turned his head, and took up the conversation to thank her: "Thanks, senior sister, it's still my own senior sister who cares for me."

Tang Zhenyi looked disgusted and took Du Zhaoyu's hand. "I'm caring for my junior sister. Zhaoyu, from now on, just call me senior sister, just like Lin You does."

Du Zhaoyu smiled sweetly. "Senior sister, then you can call me Little Du, or you can call me Xiao Yu'er, just like Lin You does."

With that, the socializing was a complete success.

The moment Lin You entered the laboratory, he had checked the time on his phone; thirty-six minutes had passed since he entered.

Watching Lin You start to study, Tang Zhenyi and Du Zhaoyu exchanged a glance. Both of them sat down, took out their own study materials, and began to read.

Lin You's main study content at the moment was still to deeply master all the courses he was studying in university; he hadn't chosen his research direction like Tang Zhenyi had.

Once immersed in their studies, there was almost no communication between the three. Occasionally, when they looked up during study breaks and saw the serious expressions of the other two, they would all continue to bury their heads in their studies.

Lin You had already finished reading the book "Functional Analysis, Sobolev Spaces, and Partial Differential Equations" and had found relevant exercises to start practicing.

This content was one of Professor Zheng's main research directions. Recently, Professor Zheng would occasionally, based on Lin You's study progress, come up with a few questions on WeChat, take photos of them, and send them to Lin You to solve.

Let H be a Hilbert space, and A: D(A) ⊂ H → H be a closed, densely defined linear operator. Suppose A satisfies the following conditions...

With the pen in his hand scribbling on the scratch paper, Lin You would never have imagined a year ago that one day he would gain a sense of accomplishment and dopamine from such dry mathematical symbols.

After finishing this problem, Lin You looked up at Du Zhaoyu and Tang Zhenyi in the laboratory, seeing that they were both quietly busy with their own studies.

Lin You let his consciousness sink into the panel in his mind and clicked on the latest task, seeing that the count for "Go on a date with Du Zhaoyu in the laboratory 10 times, each time not less than one hour" had already changed to 1.

The corners of Lin You's mouth curled up, and his heart was full of smugness... Studying together in the laboratory, why wouldn't that count as a date?

A Top Student's date is just studying together; that's very reasonable, right?

Although the task count had become 1, Lin You didn't take Du Zhaoyu away. The three of them stayed in the laboratory for the whole afternoon without going out.

When it was time for dinner, Tang Zhenyi offered to treat them to a meal, but Lin You and Du Zhaoyu politely declined.

"Senior sister, Xiao Yu'er and I both have class meetings tonight."

Upon hearing this, Tang Zhenyi's eyes were resentful. "You two specifically came here to cram against me... How could I still remember that you are freshmen who just finished registration?"

Lin You coughed twice and took the opportunity to say: "Senior sister, for the next period of time, we have to undergo military training, and there are many freshman affairs. If we go to the Library and study rooms to study every day, it will be hard to find seats. In the future, can Xiao Yu'er and I come here to study often?"

Tang Zhenyi rolled her eyes at Lin You, turned around, rummaged through a drawer to find a spare key, and handed it to Lin You.

"Come on then. Anyway, I've gotten used to you cramming against me for the past half year. However, it's best if you bring Xiao Yu'er when you come in the future; if it's just you, I don't really want to see you."
