Open book is beneficial + special episode

"Do an experiment."

"Review the final exam."

"Why are you studying all day long? It's a good thing you didn't find a partner, or you would be mad at your partner." Wang Xiaonan looked at the two of them sadly, and couldn't help complaining, "I think you two are a good match, Otherwise, stay together and don't harm others."

He does not mean that.Thinking of the ambiguous scene just now, Cheng Zhou was startled, and quickly clarified: "Sister Xiaonan, don't talk nonsense."

"Where am I talking nonsense, you just don't have me in your heart." Wang Xiaonan, who was still pitying himself just now, suddenly showed a flattering smile, "Xiaozhou, let's play cards at night, or watch a movie. Order a milk tea takeaway and watch while watching." drink?"

Gu Yazhen tilted her head and curled her lips jokingly, taking a panoramic view of Cheng Zhou's guilty conscience.

"Sister, shall we watch a movie together tonight?" Cheng Zhou was a little shaken by Wang Xiaonan's words, and turned to ask Gu Yazhen for advice.

"No, I'm rushing to do the experiment." Gu Yazhen turned her eyes away and looked at the lights in the distance calmly.

"Then... I'll go to study too." The guilt of not studying overcame the temptation to play, and Cheng Zhou suddenly lost interest.If you don't watch it with Gu Yazhen, you're still missing something.

"You marry Xue Xue, I don't want you anymore!" Wang Xiaonan said angrily, "I will send you photos of roasting cold noodles in a while, so that you will have no peace." After she finished speaking, she turned her back and went to the snack street Dash in the direction.

Cheng Zhou: "..." It's too ruthless, dare to release poison late at night.

A subtle smile crossed Gu Yazhen's indifferent face, as if she had obtained the long-awaited result.

"Leave her alone," Gu Yazhen said softly, "She just finished class today, so she's in a hurry."

There is generally no final exam for graduate courses, and the final exam is usually a ppt presentation on stage, so you can be relieved before the exam week.

Cheng Zhou nodded.After what happened in the practice room just now, she was somewhat embarrassed when she was alone with Gu Yazhen again.

She thought of the blazing eyes of Gu Yazhen when she approached her, the enthusiasm was so intense that she almost melted away.Amidst the dizziness, she stood there in a daze, watching her long and thick eyelashes and rosy lips from a close distance, and finally forgot to dodge.

At that time, Gu Yazhen wanted to kiss her?Walking step by step to the chemical building, Cheng Zhou's heart could not be calm for a long time.

Memories welled up in her heart, and many signs and past events were in front of her. It wasn't that she had never thought about it before, but she didn't dare to think about it.

Gu Yazhen's every move, every frown and smile are all charming in her eyes.During these days of getting along, Cheng Zhou saw her intelligence, stability, gentleness and delicateness, and it was buried deep in his heart, and he didn't even dare to think about it.

Does Gu Yazhen really like herself?Cheng Zhou cautiously looked at the profile of Gu Yazhen beside him, for fear that his thoughts would be prying into the eyes.She moved her lips lightly, and after a long time did not speak, she sighed.Originally, I thought that I would be very lucky to be friends with her. I never expected to be her girlfriend.

The two took the elevator upstairs, and when they got out of the elevator, Gu Yazhen blocked the door for Cheng Zhou as usual.Everything was the same as before, but Cheng Zhou began to think too much because of Gu Yazhen's every movement.Slowly sitting down at the desk, spreading out the review materials, Cheng Zhou stared blankly at the same page of the textbook for half an hour.

"How's the review going?" Taking off her lab coat, Gu Yazhen walked to Cheng Zhou's desk and sat down, leaned over and folded her arms on the table, lying on her stomach, gentle and well-behaved.

Looking at each other, Cheng Zhou's face was as hot as a fire.

"I didn't eat at night, so I don't have much energy to read." Seeing Gu Yazhen staring at his textbook with a clear look, Cheng Zhou hastily told a lie.

"Didn't eat?" Gu Yazhen was stunned, her eyebrows frowned slightly, "Then I'll take you to eat some." Then she stood up and took out her schoolbag and scarf.

"No senior sister, the cafeteria is closed. And your products are still drying in the oven." Cheng Zhou stepped forward and grabbed Gu Yazhen's hand, feeling a little cold.

Gu Yazhen's hand trembled a few times, and then she held Cheng Zhou's warm little hand in the palm of her hand.With a triumphant smile, she raised her eyebrows mischievously.

Cheng Zhou: "..." How can there be an illusion of a sheep being in the mouth of a tiger.

The pride and excitement on his face were fleeting, Gu Yazhen then said with a straight face: "Then order a takeaway."

Half an hour later, Gu Yazhen went downstairs to get takeaway.

"Senior Sister, don't you want to eat?" Cheng Zhou asked while controlling his hands that were about to move, staring at the chicken fries in front of him.

"I've already had dinner, take your time." Gu Yazhen slowly unwrapped the ketchup and poured it on the lid of the lunch box.

Cheng Zhou's stomach was growling with hunger, and he stopped being polite to Gu Yazhen, picked up a piece of fried chicken and gnawed it.

The corners of Gu Yazhen's lips raised a subtle angle.

Uh... Is it not restrained and dignified enough to eat?Cheng Zhou's brain twitched, and for the first time, he cared about his appearance when eating in front of Gu Yazhen.So, she put down the fried chicken that she had eaten almost, picked up the burger and chewed slowly.

Gu Yazhen clenched her fist and put it on her mouth, she suppressed a smile and cleared her throat.

"What's wrong with you?" Cheng Zhou looked puzzled.

"There's something on your face." Gu Yazhen leaned forward and wiped the corner of Cheng Zhou's mouth with her hand.Taking advantage of Cheng Zhou's unpreparedness, she gently pinched Cheng Zhou's red cheeks again.

Cheng Zhou held the half-eaten hamburger at a loss, not knowing how to react.The skin that Gu Yazhen touched seemed to have an electric current flowing through it, and she trembled slightly to the bottom of her heart.

"Hmph." Cheng Zhou murmured dissatisfiedly, quickly turning his heartbeat and embarrassment into complaints.What does this guy want to do?It keeps her distracted and overthinking.

The phone's notification sounded, and the lock screen of Cheng Zhou's phone showed that Wang Xiaonan had sent a picture from the subject group.Gu Yazhen tilted her head, turned on her phone, and returned a photo calmly.

Cheng Zhou couldn't help being curious, and opened WeChat to see that Wang Xiaonan had indeed been poisoned late at night, and the roasted cold noodles in the photo had an attractive color, and one could feel a sweet smell just by looking at it.

Under Wang Xiaonan's triumphant emoji, Gu Yazhen replied with a picture of the fried chicken takeaway they ordered just now, with the text: "Grilled cold noodles are unhygienic, eat less."

Wang Xiaonan sent three lip-smacking emojis, and replied arrogantly: "Even if borax is really added to the dough cake, it won't burn through at 1500 degrees, I still love it."

Some time ago, it was rumored on the Internet that the chewy texture of the roasted cold noodles was due to the addition of the chemical raw material borax. Someone personally conducted an experiment, heating the thin roasted cold noodles at a high temperature of 1500 degrees, and it did not burn through for more than a minute.Wang Xiaonan obviously read the report, believed it was true but didn't take it seriously.

Gu Yazhen: "The melting point of borax is more than 700 degrees."

Cheng Zhou: "..."

Wang Xiaonan: "Senior sister, why do you treat me like this, am I not your little junior sister tooㄒoㄒ"

Seeing Cheng Zhou's indescribable expression, Gu Yazhen put down her phone and blinked innocently.

Cheng Zhou keenly received this cute and mischievous electric wave, and was suddenly shocked.How can Gu Yazhen be so cute even when she bullies others...

Indulging in Gu Yazhen's beauty and unable to extricate himself, Cheng Zhou finished his dinner without knowing it.

"Senior Sister," wiping his mouth with lingering interest, Cheng Zhou suddenly remembered the course selection that has been in full swing recently, "Have you taken Wang Ping's structural chemistry course before?"

Near the end of the term, in addition to reviewing the final exam, another major event is the first round of course selection for the next semester.In addition to elective courses that need to be assigned to popular courses with interesting content, major compulsory courses are often assigned to several different teachers because of the large number of students, so students will also choose courses based on the teacher's reputation.

It's just that the word-of-mouth of the teacher is passed down from generation to generation by several students, and there is a lot of rumours.Recently, Cheng Zhou heard countless different best course selection guides from many students, and he didn't know which one to believe, so he had to ask Gu Yazhen to find out.

"I have attended Wang Ping's class several times, and the lectures are quite satisfactory, not as good as Shen Zhong's. I chose Shen Zhong's structural chemistry back then."

"Okay." Cheng Zhou took a memo on his phone and wrote it down.Chen Junhan said that Shen Zhong's class roll call every time was very scary, and told everyone not to take his class.But Cheng Zhou believed that Gu Yazhen's approved teacher would definitely be the same.

"As for the elective courses of computer-aided chemistry and applied electrochemistry, which one do you recommend?"

Gu Yazhen pondered for a moment, then said, "It's all pretty good, it mainly depends on your interest."

Cheng Zhou lost his mind for a while: "Then, which school did you choose, Senior Sister?"

"I closed both doors."

Cheng Zhou's head was suddenly as big as a bucket, and Gu Yazhen was indeed a ruthless person who would not let go of knowledge.

"Hmm... Computer-aided chemistry sounds difficult, and I still need to learn computers." Cheng Zhou tilted his head, and the balance in his heart was tilted towards applied electrochemistry, which sounded a little easier.
