Although I still like Song Chengyi, and I only like him alone, I still have a lot of maturity now, I know what belongs to me and what doesn't belong to me, so I can see it clearly, although I have received a certificate with Song Chengyi, but in fact, I am like a mirror in my heart.

"What are you doing there?" Faced with Luo Yixia's daze that he had been indulging in for a long time, Song Chengyi had to interrupt.

"Oh, just take a look."

"Didn't you say in the morning, let me not look at your stuff?" Song Chengyi sat on the chair and asked lazily.

This guy really loves to hold grudges.

"Didn't you watch it too? I'll take a look at the courtesy. Luo Yixia smiled.

Song Chengyi didn't speak, and agreed with what Luo Yixia said.

got Song Chengyi's promise, Luo Yixia of course looked around unceremoniously.

Song Chengyi didn't know what he was looking for on the top of the bookcase, and Luo Yixia didn't care.

Later, Luo Yixia also knew what this great god was looking for and how he tossed himself, and he knew that he shouldn't have followed Song Chengyi here, it was better to listen to his mother's nagging in his own home.

Song Chengyi threw two books to Luo Yixia.

"This is what I've seen before, you can take a look at it at home this month, I'll check it regularly." Song Chengyi said casually.

The corners of Luo Yixia's mouth twitched.

I looked at "Medical Chemistry" and "Medical Physics" in my hand.

I was a little confused......

"No need...... Ha ha...... I have a lot of books on my side, but I haven't read them yet. Luo Yixia wanted to take advantage of Song Chengyi's inattention to stuff the book back.

But I didn't expect Song Chengyi to say directly: "It's okay, let's watch it together." ”

"Actually, what I want to say is that I read these two books when I was a freshman." Luo Yixia paid attention to Song Chengyi's expression, and was a little panicked in her heart.

"That's right." Song Chengyi stretched out his hand.

Luo Yixia immediately sent the book up.

It seems to have succeeded, just when Luo Yixia was secretly happy.

Song Chengyi casually flipped it over.

"What is the difference between a chemical formula and a molecular formula? Similarities and differences. ”

"Huh? I...... I'm studying medicine, not chemistry, so can't you ask something related to chemistry? Song Chengyi choked his neck and said stiffly.

"Then tell me about the relationship between chemistry and medicine." Song Chengyi continued.

Luo Yixia lowered his head, clasped his fingers, and muttered in a low voice: "It's not about chemistry." ”

Song Chengyi stuffed the book to Luo Yixia again: "The relationship between medicine and chemistry is very close, the main object of medical research is the human body, the human body is formed by various tissues, containing tens of thousands of substances composed of dozens of chemical elements, the life process of the human body, including physiological phenomena and pathological phenomena are all reactions of chemical changes in the body, so if you want to study medicine and don't want to study chemistry, it is impossible." ”

"Oh." Luo Yixia still lowered his head.

Why is that so serious...... Say something you don't understand.

Song Chengyi sighed: "I don't know what you think." Now read more books. ”

I don't know if Song Chengyi's words touched him, Luo Yixia felt that his eyes were sour, and he was very aggrieved in his heart.

Why did you study medicine...... It's not for him.

It's not to get closer to him, to have a common topic with him, to get to know him better, to see him more.

"You rest first, I'll go out first, so I won't disturb you." Luo Yixia said in a low voice, then walked out with the book in his arms, and helped Song Chengyi close the door.
