Chapter 171 Someone is explaining a problem to me
Friday morning sunlight slanted in through the window, making the desks shine.
Song Huan pulled Xiao Yunqing's physics test paper over and scanned it from top to bottom.
There weren't many mistakes, but every wrong answer was stuck on the same thing: determining the direction of electromagnetic induction.
He took a pen and drew a diagram on the draft paper, clearly marking the rails, conductor rod, magnetic field, and arrows.
"The right-hand rule states that magnetic field lines pass through the palm, the thumb points in the direction of motion, and the four fingers indicate the direction of the electric current."
He pushed the paper over.
Xiao Yunqing took it and stared at the picture for a few seconds.
He gestured on the paper, showing which way his palm was facing, which way his thumb was facing, and how his four fingers were bent.
"so?"
"Um."
She drew it again on the paper, and this time she got it right. She pressed the pen a little harder, as if she wanted to carve that direction into the paper.
Song Huan turned to another page and pointed to a big question.
"Your approach is correct, but you substituted the wrong formula in the second step."
He wrote the correct formula next to it and then wrote out the derivation process again.
Xiao Yunqing leaned closer to look, her hair almost brushing against his face.
He spoke slowly, pausing at each step to wait for her to nod.
She nodded, and he continued.
She frowned, and he repeated himself in a different way.
After I explained it four times, she finally said "Oh," and took the pen to write it herself.
Song Huan leaned back in her chair, watching her as she bent over her work.
Since that rainy day, she has never mentioned breaking up with him again.
Song Huan was very pleased.
The proud and aloof girl finally forgave herself.
He felt that if he could become a writer in the future, he would definitely write down what happened today.
I've already thought of a name: "The Story After the Rain".
He let the thought linger in his mind, and a slight smile appeared on his lips.
Xiao Yunqing finished writing the last question, put down her pen, and looked up.
Song Huan looked at her and smiled. "Go, Little Cloud, go and win that damn physics competition first prize."
Xiao Yunqing rolled her eyes at him, but her face turned red.
Her cheeks flushed red to the tips of her ears, and she looked almost translucent in the morning light.
"understood."
……
In the afternoon, Xiao Yunqing's exam room was on the third floor of the main building. The corridor was quiet, with only occasional footsteps echoing as people came out of the exam room to use the restroom.
Xiao Yunqing sat by the window, with the exam paper spread out in front of her, her palms sweaty.
She opened her pencil case and rummaged through it.
The pen was lying at the very bottom.
It's black, with a red "福" (good fortune) sticker on the cap. The edges are slightly curled up, and the ink has faded.
She picked it up and held it in her hand.
She had held the pen countless times, making it smooth and warm to the touch.
That was the pen Song Huan used for her high school entrance exam; she chose it, and she pasted the "Fu" character on it.
Later, she got the pen and kept it.
I've replaced pen refills one after another, but the pen casing remains the same.
She held the pen in her hand, and her heart slowly calmed down.
It was as if someone whispered something in her ear; the voice wasn't loud, but it worked.
She couldn't help but smile, her lips curving upwards and her eyes crinkling as she looked down at the pen as if it were something very precious.
Someone was watching her from the corner.
His gaze swept across her face, paused for a moment, and then moved away.
Chu Ran sat in the last row, against the wall.
He was looking in that direction.
The girl by the window had her head down, her profile illuminated by the sunlight, and she had a shallow dimple when she smiled.
He turned his gaze back to his own exam paper.
My heart is beating a little fast, and my palms are sweating.
The bell rang from the corridor, signaling the start of the exam, and the candidates began answering the questions.
Xiao Yunqing took off the pen cap and began to write.
The questions at the beginning weren't difficult; they were simpler than what she usually did.
She thought about it for a while, but wrote each step very steadily.
Fill in the blanks, all done.
Multiple choice questions, all answered.
Calculation problems, finished.
Turn to the last page.
The last big question.
She read the question once, but didn't understand it.
I read it again, but I still didn't understand it.
Electromagnetic induction: a guide rail, two conducting rods, and a changing magnetic field.
She frowned, the pen tip touched the paper, but didn't fall.
He rested his face on his right hand and twirled a pen in his left.
The pen spun between my fingers, then spun again, and the red "Fu" character sticker spun along with it, dazzling my eyes.
She stared at the character "福" (fortune/blessing), and a thought suddenly popped into her mind.
If it were Song Huan, how would she answer this question?
He would definitely first analyze the forces, then set up the equations, and then...
Suddenly, her eyes lit up.
Ideas popped into my head, as if someone had removed something blocking my view.
She gripped her pen tightly, drew a diagram on the draft paper, wrote down two equations, substituted them in, and calculated the answer.
She wrote the steps on the answer sheet, line by line, her handwriting more illegible than before, but every step was there.
It's finished.
She capped the pen and placed it on the table.
He touched the character "福" (fortune) with his finger once, then again.
She chuckled again, very softly, as if she couldn't help it.
The bell rang again.
"Stop writing, hand in your paper."
The sound of chairs scraping against the floor echoed in the examination room. Some people sighed, some whispered their answers, and some slumped over their desks, unwilling to move.
Xiao Yunqing put the test paper on the table, stood up, stuffed her pencil case into her schoolbag, and zipped it up.
The corridor was full of people.
She leaned against the wall, put her schoolbag on, and looked down to check the zipper of her pencil case.
Someone suddenly walked up from behind, their steps very light, and stopped beside her.
She looked up.
Chu Ran stood in front of her.
He was wearing his school uniform neatly, the zipper was zipped up all the way, his hair was combed smoothly, his hands were hanging at his sides, and he was gripping the pencil case strap tightly.
Her face flushed slightly, and her lips moved, but she didn't make a sound.
"Xiao Yunqing".
His voice was very soft, squeezed out from his throat.
Xiao Yunqing was stunned for a moment.
She didn't expect him to take the initiative to greet her.
They didn't speak to each other after the group meeting. Occasionally, when they bumped into each other in the corridor, he would walk past with his head down.
She quickly smiled, quite naturally, "Chu Ran? You're in this exam room too?"
Chu Ran nodded, gripping the pencil case strap even tighter.
"How...how did you do on the exam?"
The sound was still soft, but a little more steady than before.
Xiao Yunqing thought for a moment, "It's alright, I spent a long time thinking about the last big question."
Chu Ran opened her mouth, wanting to say that the question was actually not difficult and could be solved using two methods.
But the words stuck in his throat.
He took a deep breath, his chest puffed out, and said, "If you... have any questions you don't know how to answer, you can come to Class 1 and find me. I can teach you."
After he finished speaking, his face turned even redder, reddening from his neck to the tips of his ears. His eyes were fixed on the ground, and he dared not look at her.
His heart was pounding in his chest, so fast that his mind went blank.
Xiao Yunqing waved his hand, smiling naturally, as if he were talking about something very ordinary.
"No need, someone is already helping me with my problems."
She adjusted the straps of her backpack over her shoulder. "But thank you anyway. I'm going now. Goodbye."
She turned and left.
Her ponytail swung as she walked briskly down the corridor.
Sunlight streamed in through the window, falling on her and casting a long shadow on the ground.
Chu Ran stood there, watching that figure walk away into the distance.
The ponytail swayed briefly at the end of the corridor, then turned and disappeared.
The corridor was empty; he was the only one left.
Sunlight streamed in through the window, falling brightly at his feet.
He stood there for a long time, then looked down at the pencil case in his hand, turned around and walked downstairs.
