After class, Yan Mo came to the study room with joy. At that time, Shen Siyan had already arrived, and he was sitting upright reading a book. She approached briskly and sat down beside him.

Shen Siyan flipped through the book, didn't raise his eyes, and just asked flatly, "Which subject do you want to review?"

Yan Mo smiled, and embarrassedly took out a thick stack of books from her schoolbag: "Can I say, I don't know any subjects?" She pursed her lips, biting her nails weakly, and blinking her bright eyes innocently.

Shen Siyan paused his hand that was turning the page, but there was not much expression on his face, as if he was not surprised by this answer. Then, he took out a test paper from his schoolbag and motioned for Yan Mo to do the questions, and he began to help Yan Mo mark the key points in the book.

When he opened Yan Mo's chemistry book, there were no notes in it, and the book was very new, just like when it was first published.

"Your book is clean. Shen Siyan said with a smile.

Yan Mo was a little weak-hearted, pretended not to hear his cynicism, and buried her head in the test paper.

Yan Mo looked at the test paper in front of her and read the question softly: X, Y, Z, W are all short-cycle elements... Which of the following statements is incorrect?

A.W's oxides can be used to make solar cells

B. The alkalinity of the hydrate corresponding to the highest valent oxide is stronger than that of X

...

This is a difficult question, why can't I read a word... Yan Mo bit the pen and thought so, the corner of his eye secretly glanced at him, and saw that he was concentrating on her key points, and he was embarrassed to disturb, so he lowered his head again and continued the movements in his hands.

When hydrogen is produced by the reaction of zinc flakes with 1mol•L-1 dilute hydrochloric acid, which of the following measures cannot increase the hydrogen generation rate?

A. Heating the reaction system

B. Add a small amount of NaCl solution

...

What are these topics? Why do you know each word separately, why is it so difficult to understand when you put it together? I don't know why you want to set up the subject of chemistry, it's really difficult...

Yan Mo first skipped the first question, and then skipped the second question, and just like that, he skipped to the end in one jump. Even she herself is a little embarrassed, she can't even answer a question, this is too much of a failure, right?

Yan Mo scratched her head and looked depressed, but this sense of shame only lasted for a few seconds, and she gave up struggling, with a calm expression of "It's that the test paper is too difficult, it's not that I'm too stupid".

And the moment she was relieved, her thoughts began to spread wildly, and she had no intention of doing the question at all. She didn't even realize that at some point, his name was densely written on the test paper, once, twice, three times...

Gradually, a wave of sleepiness came over her, and she yawned, chose a comfortable position, and fell asleep against her desk.

Shen Siyan was so focused on the key points that when he looked up, she was already meeting with the Zhou Guild, and the corners of her mouth were still smiling, as if she had had some kind of sweet dream.

Shen Siyan didn't know how to describe his mood at the moment. Was it expected, or was it helpless?—he shook his head and poked the crook of her arm with the barrel of his pen, but she just changed her position and continued her dream.

"Yan Mo!" Shen Siyan reached out and grabbed her ear, and there was a bit of anger in his deep voice.

Yan Mo, who was sleeping soundly, seemed to feel a murderous aura, and suddenly raised her head, but the corners of her mouth couldn't help yawning, looking sleepy.

Shen Siyan looked at Yan Mo's test paper, and a puddle of saliva smeared on the test paper.

Yan Mo subconsciously followed his gaze, her pupils couldn't help but widen, she quickly wiped the corners of her mouth and smiled.

Shen Siyan took her test paper and glanced at it quickly, the entire test paper was empty except for the place that should be filled, and the others were full, he pointed to one place and asked, "What have you written?"

She replied truthfully: "Shen Siyan." ”

Shen Siyan gave her a roll of his eyes angrily, shook his head and sighed lightly.

"Oops~ This chemistry topic is really difficult, I understand every word, but I just don't know what it means when combined, I want to do it well..."

"Forget it, you first memorize the key points I marked for you, and the example questions I marked must be reviewed in a focused manner, and then ask me if you don't understand, so that there will be basically no problem in the exam. ”

Yan Mo blinked her big shining eyes and asked with a smile, "Shen Siyan, you say, what is in your head?"

"Don't talk, read a book. ”

"Oh. ”

Yan Mo has always been aware of current affairs, so she obediently reviewed it, and carefully memorized the key points that Shen Siyan had drawn for her.

He looked up at Yan Mo, who was serious, she was not as noisy as usual, and she had a special feeling, which couldn't help but make him hook the corners of his lips.

It's just that quiet moments are always short-lived, and it doesn't take long for her to start again...

"Shen Siyan... How do you write this reaction equation?"

"Shen Siyan... How do you do this analytic geometry problem?"

"Shen Siyan... What does this English word mean?"

...

Shen Siyan was disturbed by her series of questions, and he couldn't read well at all, but when he looked at Yan Mo, his eyes were just filled with helplessness, and he didn't look annoyed, sighed lightly, and patiently answered her.

After that day, Yan Mo would study from the study room every day after class, and if she didn't understand something, she would ask Shen Siyan for advice.

Shen Siyan shook off a test paper, "This is the test paper I helped you out, give you an hour to do the questions, and if you can't do it, skip it first." I'll see how much you have mastered. ”

"Ahh

"No, you can't. ”

Before he could finish speaking, he was interrupted.

"Oh. Helpless, Yan Mo could only continue to write hard.

Shen Siyan reviewed the papers, and he made progress every time, which was very good, and he was very satisfied.

Time passed, and in a blink of an eye, Yan Mo was already sitting in the examination room. She looked at the test paper in her hand, and couldn't help but sigh that this genius has a strong brain, and he has actually passed all the key points he has scored!

Yan Mo wrote hard, her face was full of confidence, and the tip of the pen was relaxed and happy, as if even something as complicated and difficult as the exam had become wonderful.

After the exam, she had expectations for the exam results for the first time. At the moment when the test paper was distributed, she was nervous and excited, and even she was surprised when she saw the results.

Yan Mo trotted all the way and came to Shen Siyan ecstatically, wanting to share her joy with him as soon as possible.

"Shen Siyan, look... I actually scored more than 500 points, this is the first time I have ever scored such a high score..."Yan Mo pointed to her report card, as if showing off her achievements to him.

Shen Siyan glanced at the string of numbers as if carelessly, then raised his hand, touched her head gently, and said with some relief: "Very good, keep it up." ”

He looked at her, his eyes smiling.

Yan Mo was also smiling, her eyes were bent into a crescent moon, and they were full of happiness, and even the air was filled with the smell of happiness...
