Chapter 1, Rebirth in 1999

Chen Xiao opened the somewhat worn tin stationery box on the desk and used the reflective lining inside the box to look at himself

Teacher Liao waited for a while, only to find that no one raised their hand to answer. The students looked at the question with blank expressions, unsure of how to approach it

Influence + 6, cumulative influence 9

Subsequently, Shen Wei bit her lip and took out her notebook to record all the methods of solution.

His chalk writing is fluid, and the characters are strong. A few minutes later, Chen Xiao completed the solution

Teacher Liao in mathematics looked at Chen Xiao, who was lost in thought, and heavily slapped the table, asking: "Who can solve this problem?"

If explained in a more metaphysical manner, Chen Xiao has been reborn into a parallel version of himself, and the space-time is somewhat disordered

What!

Teacher Liao clapped his hands with great joy and said: "Chen Xiao, you may go down now. Remember to rest a bit earlier tonight, otherwise you won't have the energy in class."

Teacher Liao praised the second method while observing it! This approach is somewhat more ingenious and simpler than the first, but it requires a more solid and varied understanding of the underlying concepts. At this moment, Teacher Liao took the lead in applauding

[Technology Tree: Medical Biology (Not Activated); Physical Chemistry and Mechanics (Not Activated); Computer Information (Not Activated) ... ... ]

The classroom in the afternoon is very quiet, with only the slightly tense breathing of everyone during the *picture* book lesson.

The stock market, real estate, Bitcoin, and the explosion of internet technology; as long as one of these opportunities is seized, even a pig can soar into the sky

If the subsequent exams yield better results than the entire class or even the whole school, will it lead to greater influence?

Chen Xiao thought it was exhausting

The appearance remains the same, but has become considerably younger

Just as Chen Xiao was about to come down, some information suddenly flashed through her mind

Shen Wei's hand was already suspended in the air, and she looked up at Chen Xiao

The guys behind him, Jiang Wei, also gave Chen Xiao a thumbs up: "Xiaozi, you are really impressive!"

Tomorrow is the first exam, everyone should still muster some spirit. I just discussed a question that was meant to be an easy point, yet many of you could not answer it. Now, let us continue to examine this question: find the equation of the circle that has the minimum distance to the line x - 2y = 0

Such a difficult math problem, being able to come up with one solution is already impressive! Chen Xiao actually has another solution!

Shen Wei's deskmate, Su Qiao, wore a look of discomfort, mumbling something under her breath that was unintelligible.

He took out a notebook and recorded some important matters in it. If this world is fundamentally similar to the historical world of books he once knew, even if the technological levels are inconsistent, certain trends are bound to emerge.

Chen Xiao continued to write on the blackboard: "Method Two: ... ... Consider it as a quadratic equation in b. Since the equation has real roots, the discriminant must be non-negative, that is, △ = 8 (5d² - 1) ≥ 0..."

Chen Xiao was somewhat bewildered; he had merely had a bit too much to drink and spent a night at the hotel, so how did he end up in 1999?

Chen Xiao also wanted to gain some influence, saying: "Teacher, I have another solution."

Influence + 3, cumulative influence 3

The girl Shen Wei, sitting not far in front of Chen Xiao, was intently watching Chen Xiao's problem-solving steps, quickly comparing them with her own thoughts

Before her rebirth, Chen Xiao was born in 2019

Very good! Our classmate Chen Xiao is truly exceptional! Mathematics is not merely about simple calculations, but rather a way of thinking. I encourage everyone to actively learn from classmate Chen Xiao

Chen Xiao looked at this unfamiliar era, feeling bewildered

Chen Xiao shuddered, regaining her senses as she looked at everything before her

Father Chen Qiang is an ordinary worker at the Jiangcheng State-owned Machinery Factory, while mother Lin Hui does not have a job and sells some breakfast and stationery at a stall outside the factory's residential area. The family's financial situation is very tight

The memories of this body surged into Chen Xiao's mind in an instant. However, the current Chen Xiao, although sharing the same name and appearance, has a completely different life experience. While his academic performance is commendable, his family situation is relatively difficult

Chen Xiao's parents before his rebirth were a university professor and a doctor, but they tragically passed away in a car accident at a very early age

Before her rebirth, Chen Xiao resigned from a research institution to start her own business, ultimately becoming the CEO of a technology group, having long since achieved her "small goal"

That's impressive! If Chen Xiao's English were a bit better, they could aim for the top scorer in the college entrance examination

Emotionally, I not only reincarnated in 1999, but also brought with me future technological systems

When Chen Xiao put pen to paper, the entire class erupted in enthusiastic applause

Chen Xiao picked up the chalk and wrote the answer on the blackboard: "Let the center of the circle be P(a, b) and the radius be r. Then the distances from point P to the x-axis and y-axis are │b│ and │a│ respectively..."

Su Qiao's expression was particularly grim, as he pondered the solution that Chen Xiao had just provided and what it truly entailed

He called out: "Chen Xiao, please come up and answer."

The name is still Chen Xiao, but the experiences are completely different

And - the - book "Indeed, it is Chen Xiao! Only he is capable of answering this."

Teacher Liao furrowed his brows and raised his voice a few notches

Note: Increasing influence to a certain value can unlock future technologies. Unlocking the first technology requires 20 points of influence

In five minutes, Chen Xiaoyang elegantly completed the second solution.

He has high hopes for Chen Xiao. Although this boy comes from a less privileged family, he is diligent and hardworking, making him a promising student.

Teacher Liao stood behind Chen Xiao, observing Chen Xiao's answers while continuously nodding in approval. Truly a student he had high hopes for! While the entire class struggled, only Chen Xiao succeeded.

A piece of chalk fell on Chen Xiao's head

On the blackboard is a mathematics problem: "Let the circle satisfy the following conditions: 1. The length of the chord intercepted by the y-axis is 2; 2. The circle is divided into two arcs by the x-axis, with the ratio of their arc lengths being 3:1. Among all circles that meet conditions 1 and 2, find the equation of the circle for which the distance from the center to the line ι: x - 2y = 0 is minimized."

Bang

He does not want to be reborn! This time, he has transformed from a big boss into an ordinary high school student, starting from zero to strive for success

This question is so difficult! I cannot understand the solution steps that Chen Xiao wrote at all

Shen Wei watched Chen Xiao return to her seat, fidgeting with her fingernails, feeling distressed and puzzled. Why is it that she couldn't even come up with a single solution?

How can one increase influence

The students were engaged in lively discussions

Chen Xiao is somewhat confused

Not only Teacher Liao, but the entire class was shocked

At this moment, Chen Xiao's mind was still in a daze, but when the teacher called his name, he still walked up.

Teacher Liao continued with the lesson, while Chen Xiao was no longer listening

The time is completely wrong

The year 1999, this was the eve of a great storm.

A teacher wearing thick glasses is writing math problems on the blackboard, while a countdown to the college entrance examination hangs on the wall—December 16, 1999, with 205 days remaining until the exam (the exam in 1999 is scheduled for July)

He recalled the information he had learned from news articles, biographies, and so on, and wrote down some important events: the establishment of Penguin Company, the free availability of 361 antivirus software, real estate reform, Ali's online sales, the birth of the Pingguo phone, and several bull and bear markets in the history of A-shares

Moreover, Chen Xiao has always been engaged in the field of technology, and this aspect of mathematics is not difficult for him.

This question is very simple! The college entrance examination math problems from 1999 are much easier than those from my own era

Just stepping onto the podium to answer questions in front of many people and astonishing everyone has increased one's influence

Mathematics genius! Truly impressive!
