Eleven-thirty AM to two PM.
Two and a half hours was the time for students to have lunch and then rest.
After finishing lunch, most students returned to their classrooms for a nap or to review problems.
For those with the means, like Xia Nuannuan, they usually went home to nap before coming back.
However, at twelve-thirty today, Xia Nuannuan returned.
"Why didn't you go home to nap before coming back?"
Qin Tian stood up and looked at her with surprised eyes as he asked.
"I, I'm not sleepy today."
Xia Nuannuan replied with a slight blush, walked in, and sat down at her seat.
She couldn't calm her mind, and indeed, she felt no sleepiness at home.
Furthermore, she felt that her mother might have sensed something, which made her a bit nervous, so she simply returned to school.
"I don't feel very sleepy either."
Qin Tian said with a smile.
It was because he had just been reborn, and he needed to sort through various memories of his past and present lives, as well as future plans and so on.
He definitely wouldn't be able to sleep during this lunch break.
Of course, reviewing problems was also out of the question.
He already mastered all high school knowledge; what else did he need to do?
"Then should we go to the track and field for some exercise?"
Xia Nuannuan suddenly proposed.
"Hm?"
Qin Tian looked at her with surprise.
Xia Nuannuan's pretty face blushed, and she shyly lowered her head.
"Ahhh, what a fool I am, why am I in such a hurry? This is too embarrassing."
She was going mad internally, feeling like her face was burning intensely.
"It's too hot outside now, let's talk about exercising before evening self-study."
Qin Tian said, trying to suppress his laughter.
How blind was he in his past life? Such a cute girl sat next to him for half a year, and he remained completely unmoved.
"Okay."
Xia Nuannuan replied, as quiet as a mosquito's hum.
"If you're not sleepy, you can do some problems. I can teach you if you don't know them."
Qin Tian added.
"Pfft!"
A snicker came from the front.
Qin Tian frowned and looked displeased at Qiu Man and Cui Ying in front of him.
Xia Nuannuan also knitted her brows, her baby-fat cheeks clearly showing displeasure.
She was accustomed to being laughed at.
But hearing Qin Tian being ridiculed made her inexplicably angry.
"What are you laughing at? Is there anything funny?"
Qin Tian questioned with a cold expression.
Upon hearing this, Cui Ying and Qiu Man immediately lowered their heads to read their books, pretending nothing had happened.
Given Qin Tian's previous harsh methods towards Xu Ying, they were now quite wary of him.
"You're being very impolite, it's too much."
Xia Nuannuan couldn't help but reprimand them.
For someone who was used to enduring mockery and injustice and had never argued with anyone, this was already a strong tone.
Qin Tian looked at her with surprise.
In the front row, Cui Ying and Qiu Man still remained silent.
"Forget it, no need to pay attention to them, let's do the problems!"
Qin Tian said to Xia Nuannuan.
"Okay!"
Xia Nuannuan nodded slightly, took out a previous provincial college entrance examination paper from last year given by the math teacher, and quietly began to work on it.
Her scores in Chinese and English were relatively good, ranking in the top ten in the class.
However, in math, physics, chemistry, and biology, she was quite lacking.
When she reached the third multiple-choice question, she started struggling, biting on her pen.
"Don't bite your pen, it's dirty!"
Qin Tian reached out, took the gel pen from her hand, and asked with a smile, "Can't you do this problem?"
"Mm!"
Xia Nuannuan nodded with a sheepish smile.
"Then I'll explain it to you."
Qin Tian smiled and began to explain:
"This question is asking for the slant height of this cone. Since the radius of the base and the lateral surface展开图 is a semicircle, we can draw a diagram like this..."
As if peeling back layers of silk, Qin Tian explained the solution approach and steps in the most intuitive and understandable way.
Xia Nuannuan, standing beside him, already had her eyes full of admiring little stars.
Cui Ying and Qiu Man, who were eavesdropping with their ears perked up, exchanged looks of disbelief.
They were also doing this paper, and they had already attempted the problem Qin Tian was explaining.
It wasn't a particularly difficult question.
But he was the one who always ranked in the bottom three in every exam!
Moreover, Qin Tian's problem-solving approach and methods were much simpler than theirs.
How was this possible?
"Why are you looking at me like that, did you understand?"
Qin Tian asked humorously.
"Mm-hmm!"
Xia Nuannuan nodded like a pecking chick, her voice filled with excitement, "Qin Tian, you're truly amazing, it's easier to understand than what the math teacher explains. Are you actually this good at studying?"
Qin Tian laughed heartily: "I just didn't want to pretend anymore. I used to think it was quite comfortable being a slacker, but now that the college entrance examination is approaching!"
Cui Ying and Qiu Man in front heard this and almost rolled their eyes to the heavens.
They didn't believe such nonsense, thinking it was just a fluke, a coincidence that Qin Tian had seen this problem before.
"So that's how it is!"
Xia Nuannuan, however, firmly believed him. Her bright, lively eyes sparkled as she looked at him, her face filled with admiration and reverence for the score-controlling academic.
"Ahem..."
Qin Tian's old face reddened, and he changed the subject: "Your liberal arts scores seem quite good, why didn't you choose liberal arts back then?"
Xia Nuannuan was taken aback and replied, "My dad also wanted me to choose liberal arts, saying it would be easier. He had everything arranged for me, and I wouldn't need to find a job later... As I listened, I felt very unconvinced, so I enrolled in science against his wishes."
As she said this, her small mouth pouted slightly, and her bright eyes showed a hint of stubbornness.
"I see!"
Qin Tian nodded with a smile.
He didn't expect Xia Nuannuan to be so strong-willed.
But then again, if she didn't have a strong sense of self-esteem, how could she have gone abroad to study later and successfully transformed from a chubby girl into a beautiful and wealthy woman!
Given her family's financial situation, staying in China and following the path her father arranged would have also led to a bright future and been much easier for her.
"Let's continue doing the problems. I'll explain again if you don't understand."
Qin Tian returned the pen to her and said with a smile.
"Mm-hmm, Qin Tian, thank you."
Xia Nuannuan thanked him gratefully.
"You don't need to say thank you anymore in the future; it's for our promise."
Qin Tian winked.
Xia Nuannuan's face instantly flushed, and she hurriedly averted her gaze and lowered her head.
Afterward, Qin Tian continued to explain the math problems on the test paper for her.
Xia Nuannuan's math level indeed needed a good amount of tutoring.
She couldn't do more than half of the entire test paper.
Fortunately, the math experience pack Qin Tian had exchanged made him completely proficient in high school math knowledge.
Coupled with the eloquence he had developed through his career in his past life, his explanations were concise and thorough, making it easy for even Xia Nuannuan, a beginner student, to understand.
For problems Qin Tian considered particularly important, after explaining them, he would specifically find similar types of problems for Xia Nuannuan to practice.
The results proved that his tutoring work was very effective.
It was likely that Xia Nuannuan would no longer be clueless when encountering similar problems in future exams.
During this process of explanation and problem-solving, their relationship had unknowingly grown much closer.
