Open book is beneficial + special episode

Should I start doing additional questions?Cheng Zhou had strong self-doubt.In her opinion, the existence of additional questions is to appease the dissatisfaction of Xueba because the test paper is too simple.And she, Cheng Zhou, really hasn't done any additional questions since she went to college.

Cheng Zhou has developed a good habit of not leaving blanks in exams since high school.The teacher in charge of the high school said that if the test paper is difficult and everyone can't answer it, writing the word "solution" might get you a point.Adhering to the principle that being able to write a sentence is a sentence, Cheng Zhou calmed down his excitement after finishing the paper, and began to study the first additional question.

Sure enough, there is no clue at all, she thought.Even so, she still copied all known parameters on the answer sheet as usual.

Copying like this, Cheng Zhou for some reason remembered the beautiful font that Gu Yazhen wrote on the back of the outline last night.Senior Sister Gu is good-looking, why is her handwriting so beautiful?

Cheng Zhou's mind was empty, from Gu Yazhen's words to Gu Yazhen's face, and then recalled Gu Yazhen's voice and words.

By the way, the story line.Cheng Zhou closed his eyes, and reviewed in his mind the materialized "story" that Senior Sister Gu told last night.When she opened her eyes again, she suddenly realized.She found that there were only two formulas in the story that were closest to the known quantities written on the test paper in front of her.These two formulas are separated by two full chapters, Cheng Zhou felt that it was not easy for him to think of them together.

After transcribing the two formulas she had memorized on the paper, she substituted one of them into the other in the spirit of treating a dead horse as a doctor, removed the unknown, and then tried another similar small formula , I didn't expect to figure out the answer in the end.

Cheng Zhou was shocked, and was moved by his own wisdom for the first time in his life.Before she had time to recollect, the bell rang at the end of the exam.

Uh... there's one more question I haven't done yet.

In every exam, a circle of scumbags is always drawn in the examination room with Xueba as the center, and the knowledge line radiates from the center to the outer circle.Since this process involves various unimaginable illegal operations, this surging undercurrent can be described as thrilling.And when the bell rang at the end of the exam, the transaction progress bar quickly accelerated. At this time, the slow but steady output of knowledge could not be reconciled with the blank test papers of the scumbags, and a bloody storm blew up in the exam room.

Cheng Zhou had already put down his pen and lowered his hands.She caught a glimpse of Chen Junhan taking advantage of the fact that the invigilator was collecting the test paper with his back turned to her, and pulled Brother Shui's paper directly in front of her, copying it frantically; and Zhong Qi also stood up, nervously revising the answer accordingly.

"Everyone, pay attention to the discipline in the examination room!" The invigilator shouted loudly, but there was nothing he could do.The examination room was in chaos, and the law does not blame everyone, so he couldn't take care of it at all.

Compared with the two fellow sufferers, Cheng Zhou's face was full of cuteness.She wrote the questions carefully throughout the whole process, but she didn't know that she had already been included in the knowledge radiation circle.In the eyes of other insiders, she is as inexistent as air, but to Xie Feifei behind her, she is a thick lead plate that shields the ray of knowledge.

After the invigilator walked past Cheng Zhou with a serious face and put away the papers of their row of students, only a "bang" sound was heard behind him, Xie Feifei slammed the chair board hard, and walked out with a gloomy face out of the classroom.

Chapter 4

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 through 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 brown 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.
