You're dumping me, huh? Fine, then I'll just pick up the school beauty and make her my wif

"hiss--"

Jiang Che gasped, clutching his chest with one hand and quickly supporting the clumsy little girl in his arms with the other. "Su Qinghe, have you practiced Iron Head Kung Fu? If you had bumped your head on me like that, I would have had a heart attack even if I didn't have one."

Su Qinghe was also stunned by the impact, her forehead flushed red, but she still clung tightly to Jiang Che's clothes at the waist, burying her head in his chest and rubbing against him, her voice muffled: "Who told you to scare me just now..."

"I was just giving you a heads-up, you understand?"

Jiang Che ruffled her hair haphazardly, turning her once smooth long hair into a messy bird's nest. "Alright, let go, or I'll suffocate."

Su Qinghe reluctantly let go of his hands and sat back down on the edge of the bed, placing her hands obediently on her knees, but her little face was filled with an unconcealable smile, looking silly.

Looking at her silly, worthless appearance, Jiang Che's pent-up frustration had long since vanished.

Although their relationship isn't officially defined yet, once they've talked things out, getting along is much more comfortable than the previous cautious, tentative approach.

"Sit still and don't move around, I really need to do my homework."

After comforting Su Qinghe, Jiang Che turned around again and pulled the math test paper that had been neglected for half a day back in front of him.

I couldn't concentrate on writing because I had something on my mind, but now that it's resolved, I feel great, and even this mess of scribbles looks much better now.

The room fell silent again.

Su Qinghe sat cross-legged in the back, still not playing on her phone, and just listened quietly.

This feeling is wonderful.

Before, she could only watch Jiang Che's back from afar, watching him run on the court and sing on the stage, but she never dared to hope that she could be so close to him.

Now, he was sitting less than two meters away from her, his breathing clearly audible.

Su Qinghe felt a sweet warmth in her heart, like a child who had secretly eaten candy.

It seems she's become a little more integrated into Jiang Che's world.

However, this warm atmosphere didn't last long before it was broken by an annoyed "tsk".

Jiang Che twirled the pen in his hand, and finally it fell to the table with a "thud".

He stared at the last big question on the test paper, his brows furrowed into a deep frown.

This question is ridiculously difficult. I could barely manage the earlier steps, but when it came to the crucial differentiation part, the formulas seemed to be playing hide-and-seek with me, and I just couldn't remember them.

"What's wrong?" came the girl's soft voice from behind.

Jiang Che sighed, leaned back in his chair, and casually stretched out his long legs: "It's nothing, just ran into a roadblock. This question is beyond the syllabus; I guess the teacher deliberately put it there to annoy us."

"Well... how about I take a look for you?"

"What do you think?" Jiang Che raised an eyebrow, turned his chair around to look at her, and said with a hint of teasing, "Su, the campus belle, I know you have good grades, but you're a humanities student, right? This is senior year science math, and..."

He pointed to Su Qinghe's unfocused eyes. "What do you think of your situation?"

Although it may sound a bit blunt, this is indeed a real problem.

Su Qinghe couldn't see, but the math problem had a long description, along with various diagrams and symbols. How was she supposed to solve it?

"I won't look." Su Qinghe shook her head, leaned forward slightly, and said earnestly, "Read it to me."

"Read it aloud?" Jiang Che was taken aback. "This question has three lines of conditions and a function graph. Can you understand it just by reading it aloud?"

"Give it a try."

Su Qinghe pursed her lips, her stubbornness returning. "I'm pretty good at mental arithmetic. As long as you read the conditions clearly, I should be able to try to solve it."

Jiang Che stared at her for a few seconds.

The little girl sat up straight, her face radiating confidence, and she didn't seem to be joking at all.

He forgot that arts and sciences were not important to her at all. She used to be the top student in her grade all year round, a true academic superstar.

Even if someone has been missing for more than a month, even if they have lost their sight, the things in their mind are still there.

"Okay, then listen carefully."

Jiang Che picked up the test paper, cleared his throat, and began to read the questions aloud.

"Given that the function f(x) equals lnx minus ax plus 1 divided by x, where a is a constant..."

He deliberately read very slowly, in order to express every symbol and condition as clearly as possible.

Su Qinghe closed her eyes, her brows furrowed slightly, as if she were building a model of the problem in her mind.

After Jiang Che finished reading the last condition, a brief silence fell over the room.

Jiang Che didn't rush her. He picked up the cola next to him and took a sip, thinking to himself how to give her a way out if she couldn't solve the problem, so as not to hurt her self-esteem.

After all, solving math problems for the blind is incredibly difficult, practically hellish. If someone can solve it, their intelligence would be at least comparable to Einstein's.

"The first step is to find the derivative."

Before Jiang Che could even swallow his cola, Su Qinghe already had an idea.

She explained clearly and logically: "f'(x) should be equal to 1/x square minus ax minus 1, or..."

Jiang Che was stunned for a moment, then quickly looked down at the answer key.

Holy crap?

It actually matches up!

"And then?" He became interested, put down his cola, and picked up a pen to take notes.

"Since we're discussing monotonicity, we need to look at the range of values ​​for 'a'." Su Qinghe closed her eyes, like a strategist in command. "We'll discuss three cases. When 'a' is less than or equal to 0, the derivative is always greater than 0 within its domain..."

She spoke slowly, but every word she uttered was perfectly timed.

Jiang Che's pen flew across the draft paper as he wrote, his heart pounding with anxiety.

This is more than just okay!

This is practically a humanoid computer!

Jiang Che needed a couple of seconds to process some of the steps, but this girl didn't even need to write a draft; she just calculated it all in her head.

Finally, considering the above three cases, we can derive the monotonic intervals of f(x).

Su Qinghe finished speaking in one breath, let out a long sigh, and then tilted her head, looking expectantly in Jiang Che's direction, "How was it? Was it correct?"

Jiang Che looked at the densely packed yet logically rigorous solution process on the draft paper, and then glanced at the reference answer.

Word for word.

It's even more concise and clear than the reference answer.

"Su Qinghe".

Jiang Che put down his pen, looking at her with a complicated expression. "Is there some kind of cheating system installed in your brain? This is terrifying!"

This was solved without seeing the question and relying entirely on listening!

Her intelligence is far superior to his; compared to her, Jiang Che instantly felt like an unintelligent monkey.
