Open book is beneficial

After the exam, Cheng Zhou rejected Zhong Qi's proposal to celebrate with Western food.She stuffed stationery and draft paper into her schoolbag, and happily walked in the direction of the chemical building against the crowd who were chattering about answers.

Walking downstairs of the chemical industry, she saw a familiar figure walking in the lobby through the glass door before she had time to take out her campus card and swipe to open the access control.

Gu Yazhen just happened to be holding her green leather notebook and dragging a small cart.The wheels of the trolley hadn't been oiled for a long time, and when they passed the joints of the marble tiles, they made a deafening crash, echoing in the empty lobby.

Cheng Zhou hurried forward: "Senior sister, where are you going?"

"Supplies department."

"Is this going to move things? Can I help?" Cheng Zhou looked at the long and wide metal plate of the cart, thinking that there must be a lot of things to carry.

"Yes." Gu Yazhen nodded, and reached out her hand to signal Cheng Zhou to put the schoolbag on the cart.

"It's okay, my schoolbag is not heavy, there are only a few sheets of paper in it." Cheng Zhou shook his head.In fact, there are stationery, water bottles and a folding umbrella in the bag.

Gu Yazhen didn't force her anymore, and the two walked side by side to the supplies department.

The school material office is some distance away from the chemical building. Cheng Zhou is not very familiar with this road, so he can only follow Gu Yazhen.Gu Yazhen chose a shortcut and led Cheng Zhou into a small road with no people.

The path is not wide enough for a car to pass.Towering pines and cypresses are densely planted on both sides of the road, and you can only vaguely see the ancient European-style buildings deep in the woods.The gray-green branches and leaves are intertwined with each other, covering the sky and the sun, and the path is more gloomy and hidden in autumn.

Hearing the creaking sound of the cart at his feet, and the two of them walking in silence, Cheng Zhou suddenly felt a little cold.In order to ease the atmosphere, she quickly found a topic: "Sister, we have a midterm exam today. Thank you for teaching me the study method yesterday, it is really useful."

"Yeah. It's good to use it." Gu Yazhen replied briefly.She stared intently at the ground not far away, wondering what she was looking for.

The topic that was finally provoked was quickly ended, and Cheng Zhou was a little at a loss.

"Then...to express my gratitude, may I treat you to dinner tonight?" Cheng Zhou sent out the invitation.Her voice was soft. Zhou Yuning once said that once elementary school girls open their mouths, it is really hard for them to refuse.

As soon as the words fell, Gu Yazhen rejected her without thinking: "No need."

The atmosphere became awkward again.

"You can thank me for looking at the literature." A few seconds later, Gu Yazhen added flatly.

... It was only then that Cheng Zhou remembered the document she had left out for many days.

"I... I'll watch it when I get back tonight."

"Yeah." Gu Yazhen pursed her lips, and smiled with lowered eyebrows, "The literature I gave you is a summary and covers a lot of information. Writing an outline while reading it will help you in your reading."

"Okay, sister."

"By the way, when I go back later, Xiaonan will tell you about the safety of the experiment, and you can enter the laboratory for experiments next week."

"it is good……"

Cheng Zhou felt that it would be a pity if Gu Yazhen did not become a teacher in the future.Except for studying, she seems to be indifferent to everything. When talking about studying, she is meticulous and patient, but as long as it has nothing to do with studying, she is like gold.

As the two walked like this, a swift black figure suddenly appeared from the hidden woods beside them.It passed in front of Cheng Zhou's feet in three steps and two steps, and quickly disappeared into another forest again, leaving only the rustling sound of swaying branches and leaves.

Cheng Zhou was unprepared for a moment, so surprised that he yelled "ah", and reflexively grabbed the cuff of Gu Yazhen's windbreaker.

"It's okay, it's the little squirrel." Gu Yazhen looked at Cheng Zhou's hand holding her clothes unnaturally, and comforted her in a low voice.

Cheng Zhou blushed when he woke up, and quickly let go of Gu Yazhen's sleeve.Gu Yazhen looked at her and smiled, instead of continuing to speak, she went to the edge of the woods and squatted down, making a rustling sound.

After a while, a dingy little squirrel climbed down from a tree, except for a little tan on the side of its tail.It dragged its chubby body, approaching Gu Yazhen cautiously, and stopped from time to time to observe the surrounding situation vigilantly.

Gu Yazhen took out a bag of nuts from the pocket of the windbreaker, opened it and put it on the ground.When the little squirrel saw it, he rushed forward immediately, grabbed a fruit, and quickly hid under the tree not far away.

"The little squirrel is chubby, so cute." Seeing the little squirrel pouting and chewing, Cheng Zhou was so excited that he took out his phone and recorded a video for the little squirrel.

"When winter comes, they will accumulate fat, and their chubby appearance will be more cute." Gu Yazhen stood up, still looking at the gray little guy with a smile on her lips.

"Then can senior sister bring me to see it then?" Cheng Zhou asked as he walked along.

Gu Yazhen was stunned for a while before saying, "Okay."

The two came to the supplies department, searched the shelves for a long time, and finally filled a cart full of office utensils, cleaning supplies and experimental supplies.Cheng Zhou noticed that Gu Yazhen took three small boxes, one medium box and one large box of rubber gloves, as well as a brand new notebook.Walking to the clothing area, Gu Yazhen turned around and asked her, "How tall are you?"

"165."

So Gu Yazhen took two white lab coats from the shelf, one size 165 and the other size 160.

After using the debit card to settle the bill at the cashier, the two dragged the cart back to the office.

Cheng Zhou was given a box of small gloves, a set of 165 lab coats and a notebook.As soon as she put on a brand new lab coat, she was dragged to the next laboratory by Wang Xiaonan, where Gu Yazhen and Zhou Yuning were also watching them.

"Cough cough, let me tell you about laboratory safety matters today." Wang Xiaonan glanced at Gu Yazhen guilty, and then straightened up after receiving approval, and continued, "Before conducting experiments, protective measures must be taken. Like Like me, rubber gloves, goggles, and a lab coat have to be put on..."

Wang Xiaonan showed Cheng Zhou how to put on and take off the gloves with great air.

"Then what are the detailed requirements for these three protective gear?" Zhou Yuning suddenly raised his hand and asked.

"Of course it's...to keep it clean." Wang Xiaonan glanced down at his dirty white coat, and suddenly felt unable to get off the stage.

Gu Yazhen took out a new size 160 lab coat and handed it to her.Wang Xiaonan returned with a grateful look.

"Is there anything else I need to add? About the lab coat." Gu Yazhen asked casually with her hands behind her back.

"...Uh...you have to take off your lab coat and hang it up when you leave the lab..." Wang Xiaonan turned pale, as she recalled the painful experience of rubbing her white coat on her junior sister a few days ago.

"Well, it's good." Gu Yazhen and Zhou Yuning nodded.

If Zhou Yuning didn't leave anyone alone, then in Wang Xiaonan's view, Gu Yazhen first gave her a step, and then quickly moved away.This scene of love and affection makes Wang Xiaonan feel that she has fallen out of favor in an instant.

Cheng Zhou looked at Wang Xiaonan who had an uncertain expression, closed the notebook in his hand, and asked cautiously, "Senior Sister, are you okay?"

"...Very good." Wang Xiaonan burst into tears.

Cheng Zhou was lying on the desk, wearing a dark windbreaker, dreaming sweetly.Under her arm was a dozen or so pages of English documents filled with dense Chinese annotations, and the open notebook also contained well-organized knowledge points and outlines.The windows of the office face southwest, and the sunlight outside the window in the afternoon pours in obliquely, creating a cozy and warm reading time.

Gu Yazhen came out of the laboratory, took off the mask and gloves, and hung the lab coat on the wall.She inadvertently glanced at Cheng Zhou who was sleeping soundly not far away, and then looked at the wall clock on the wall.The pointer points to quarter past two.

She went to the water dispenser to get a cup of warm water, put it on Cheng Zhou's desk, and tapped the table with her index finger.

"Going to class."

Cheng Zhou woke up from his sleep, raised his head in a daze, and Gu Yazhen's concerned expression was reflected in his sleepy eyes.

"Hmm... why did I fall asleep." She rubbed her eyes, turned on her phone and checked the time. It was indeed time to go to class.

Cheng Zhou wore a sweater today, and when he slept with his head resting on his arm just now, when he got up, there was a red mark of the sweater pattern on his left face, which made Gu Yazhen laugh.

Although he felt that the senior sister was looking at him a little strangely, Cheng Zhou didn't have time to think about it, he packed his schoolbag and hurried to the materialization class at three o'clock.

"Senior sister, I'm leaving first!" Cheng Zhou closed the door behind him.

A few seconds later, the door opened a crack again, and a hand skillfully reached in to take away the coat hanging by the door.

Then the door slammed again.

Gu Yazhen smiled to herself, picked up the windbreaker on the back of the chair and hung it back on the wall.

"Yazhen, it's rare to see you smiling so happily. What's the matter?" Zhou Yuning walked out of the laboratory with a curious expression on his face.

"It's nothing." Gu Yazhen adjusted her glasses, her face returned to seriousness, "Yes."

"What are you doing?" Zhou Yuning had a resigned expression on his face.

"Well... that's... I got a national scholarship today, and I want to invite all of you to have a meal together."
