After lying dazed on the bed for a while, Xu Yun turned over and looked around.
This was a single apartment with a total area of over forty square meters. The decor wasn't particularly luxurious, but the location was quiet, offering relatively high privacy.
Although USTC had renovated parts of the East District dormitories back in '19, the conditions for master's and doctoral dorms were generally average, except for training students.
For example, master's students shared four to a room, while doctoral students shared two to a room—although the ones on Science Island were somewhat better.
However, Xu Yun chose to live alone off-campus not because of poor dorm conditions, but because... he had a secret.
Xu Yun, currently 24 years old.
Gender: male, gender identity: male, not an extreme animal rights activist or extreme environmentalist, no depression, interest: women.
Socially referred to as that man, if he were to make the news, he'd probably be called the man, and occasionally, without reason, he'd get saddled with a surname—Guo.
At 15, he was admitted to the USTC Youth Class, graduated with a bachelor's degree at 19. After graduating, he didn't opt for a master's degree but applied for direct doctorate admission.
Xu Yun's direct PhD focus is synthetic biotechnology and systems bioengineering, which is a relatively well-known biology PhD program at the physics-renowned USTC. He is currently about to obtain his doctorate.
Moreover, he is also pursuing a master's in condensed matter physics, with only a short time left before obtaining the degree.
Friends who've attended the Youth Class should know.
Whether it's the USTC Youth Class, Yao Class Wisdom Class, or Turing Youth Class, in these top institutions, top students are often called XX God.
For instance, God Cao, God Han, God Wei, and so on.
Thus naturally, Xu Yun also earned the title of God Xu.
However, though academic prodigies are nearly invincible academically, they often appear eccentric in life, even seen as freaks.
For example, the internet-sensational God Wei, Wei Dongyi, who looked somewhat dazed because he was perpetually pondering academic problems.
Some academic genius prodigies even lack self-care ability, with parents always needed to manage their daily affairs.
In his past life, Xu Yun was one such 'genius' with severely imbalanced emotional and intellectual intelligence. Though not to the absurdity of needing help with living essentials, his social circle was nearly zero until it slightly improved after 30.
Seeing this, gamer students familiar with banning mammoths must have noticed a certain word:
Past life.
That's right, past life.
Xu Yun is a reincarnator.
However, compared to some other reincarnator predecessors, Xu Yun's reincarnation was somewhat unique.
It was a winter in 2041, Xu Yun was writing an online novel titled "Where is Wu Fan," when suddenly, while writing, he felt dizzy and collapsed on the keyboard.
Upon waking, he found himself reincarnated to age 15, the day after the second round of the USTC Youth Class physics defense.
This was also a deeply impressionable life juncture for Xu Yun—since that year's defense topic was intriguing:
One problem involved a group of little green men digging for gold on the Golden Planet, eventually falling to their deaths. It required calculating the fall time concerning two different shapes and slopes and drawing a sketch of the spaceship's appearance.
Another problem included data stating the atmosphere thickness as h, causing classmates to lament its irrationality since the particle velocity space on the surface and isotropic outward wasn't h....
The problem also claimed atmospheric uniformity was magical, so Xu Yun ultimately chose to submit the score for this question to the state, as his severe OCD couldn't manage otherwise.
As a long-time online novel-writing reincarnator, Xu Yun naturally understood the coolness of reincarnation settings:
Leveraging knowledge of future events to prep arrangements, thereby earning massive wealth and social status.
But just as Xu Yun was confidently tracing back memories, he found his mind blank, remembering only a few scattered events:
Like a marathon deciding a champion, Mr. Jia still claiming to return home next week, and thirty years later Celestial Foot still reviewing Milan, etc.....
Besides these, the only other thing Xu Yun remembered was his academic knowledge learned before turning 30.
He had no impressions whatsoever of other derived scientific technologies, historical events, or competition results.
Yet, on the other hand.
Despite his blurred memory, his mindset and experiences from his forties were retained entirely.
This gave him a much higher maturity compared to peers in social interactions and self-discipline.
It is precisely due to this that Xu Yun managed to graduate with a doctorate at 24 in this lifetime—while in the past lifetime, he was 28.
In fact, the changes that occurred to Xu Yun went far beyond this...
Inside the bedroom.
Xu Yun used his left thumb to rub his temples and silently chanted a semantically ambiguous syllable in his heart:
༒༶༄༅
As the syllables escaped, Xu Yun's vision suddenly darkened.
When he regained awareness, he found himself in a dimly lit space.
This space wasn't large, only about twenty square meters, with nothing but a two-meter diameter jade-green circle at its center.
At this moment, a number is flickering above the circular ring:
300/300.
This space appeared on the second day after Xu Yun's rebirth, which was exactly ten years ago.
The size and appearance of the space from the beginning was just like now, with boundaries composed of some kind of hard solid material, much harder than waves anyway.
However, at the very beginning, the value on the central circle was '0/300'.
And at that time, the space offered the only hint so far:
The circle value will increase positively based on the amount of knowledge mastered by the 'Wall-Facer,' and the first doctoral degree must be in the biological field—the circle value was called knowledge points by Xu Yun.
It is also because of this that Xu Yun, who worked in physics in his past life, inexplicably 'defected' to the field of biology, which was exceptionally rare in the Turing Youth Class famous for physics.
Now, Xu Yun has spent a full ten years, and finally, with the completion of today's dissertation defense, he successfully pushed this score to the full value.
Perhaps sensing Xu Yun's appearance.
A few seconds later, the circle suddenly began to rotate slowly.
A few seconds later.
Three doors abruptly appeared on the light ring, each with the number '100' prominently marked.
Meanwhile, an intuitive understanding suddenly emerged in Xu Yun's heart:
He could consume 100 points of knowledge points to open any door, but only one could be opened within a certain time.
To be honest.
Even as a reincarnator, seeing this scene unfold before him, Xu Yun felt somewhat intimidated.
He even considered whether to tell his mentor Marshal Pan about this, but as soon as the thought arose, the '300' in front of him instantly transformed into three numbers, '404'.
Seeing this, Xu Yun had to relent.
Immediately, scenes of his diligent studies over the past decade began to float frame by frame, page by page in Xu Yun's mind.
With the flipping of the last image, Xu Yun took a deep breath and walked towards the door on the far left.
What?
You're asking why the left?
Of course, it's because the left one has more times!
......
Born in the late twentieth century, Xu Yun can be considered a small fan of Harry Potter.
Although in recent years, both Rowling herself and several main actors have engaged in some scandalous actions in the media, the book Harry Potter is indeed still a good read.
Even forty years later, Xu Yun still remembers Hagrid's big beard, Avada Kedavra, Voldemort's socket-like nose, the love story of Voldemort and Daili, and....
The depiction of 'door key' and 'disillusionment' in the original work.
And now, Xu Yun's feeling is somewhat similar to riding a door key:
A dizzy sensation like being stirred in a drum washing machine, clock-like ticking resembling a countdown, accompanied by a kind of sharp tinnitus...
It's estimated that when the Great Demon King Piccolo was sealed by the Demon Sealing Wave and stuffed into the rice cooker international hotel, his stay experience was similar to this.
In short.
After a fierce bout of dizziness.
With a thunk, Xu Yun fell to the ground—face down.
Yet the strange thing was, he didn't feel any pain.
He then opened his eyes and found himself lying on top of a person, who was also face down, embedded into the soft soil, with only a mane of lion-like golden hair left visible.
Seeing this, Xu Yun hurriedly crawled off the person, carefully turning him out of the soil.
This was a very young man, with a high prominent nose bridge, deep eye sockets, brows angled upwards bringing together a few bits of defiance.
The man's chest was slightly heaving, indicating he was breathing—he seemed to be merely unconscious.
But across from him, Xu Yun's breath abruptly halted.
Having once worked in the field of physics, this man's visage on portraits was already engraved in Xu Yun's DNA, and he'd seen him countless times in animations and online novels, tremoring in his coffin—even though he was actually cremated.
His name was...
Isaac Newton.
