Time is like a clear spring holding water in the palm of your hand, but it has passed quietly before there is time to react.

In the blink of an eye, a few days passed, June had ended, and July was quietly coming.

For most people, entering July means the real arrival of the scorching heat. Binhe City has always been known as the "stove". In recent days, it has lived up to expectations and entered the "stoic heat mode", declaring its majesty with practical actions.

The hot and hot summer make the workers who carry bricks on the construction site feel that the bricks in their hands are getting hotter. July also means different starts for different groups.

The students ushered in the long-awaited summer vacation. In addition to feeling that the weather is getting hotter, office workers still have to proceed step by step with tedious daily work, and secretly looked forward to the arrival of the typhoon. As for the otaku hiding in the room and blowing the air conditioner, with the launch of the new episode, it is the season of "changing wives" again.

Binhe University of Technology.

School of Biochemistry, Laboratory Building.

The bright sunlight shone on the square outside the experimental building, causing a mirage-like twist.

At three o'clock in the afternoon, Bai Xiao, wearing a white coat, walked down from the stairs of the experimental building with the experiment book in his hand, and walked in the shaded corridor, unable to help but sigh.

Bai Xiao's white coat is a long-sleeved and waist-hugging female style. The hem extends to the calves, and the front is buckled by three large-pitch buttons. Because it is a new collar, there are no creases and are extremely clean, giving the feeling of white clothes being better than snow. At this time, when worn on Bai Xiao, a slender and graceful figure is highlighted, and her flawless and slightly cold face shows her heroic temperament to the fullest.

The white coat highlights a woman's heroic spirit, which is true to be said, but she is naturally elegant with poetry and literature. She is said to be a woman like Bai Xiao.

A few days later, Bai Xiao's hair grew a little bit longer. Bai Xiao tweaked it with her hands and muttered that she could probably tie her braids if she grew any longer.

"Bai Xiao, how did you do in the exam?" Several girls who had been waiting in the corridor had already seen Bai Xiao walk out and hurriedly surrounded her and inquire about the information from her.

"It's okay. I got the test questions for filling and simulation loading of the 'affinity chromatography' column, which is quite easy."

Bai Xiao smiled and gave a few girls a "relaxed" smile.

"Is the invigilator strict?" a girl said worriedly.

At this time, Bai Xiao and the others are conducting the graduation exam for experimental courses related to enzyme engineering. The candidates will randomly draw one test question from more than 30 test questions for experiments, and at the same time answer the theoretical knowledge. The invigilator is a one-on-one invigilator, so an experiment classroom can arrange for exams of up to ten students.

This kind of exam that requires both hands-on and practical tests and answers theoretical knowledge can be said to be quite challenging. Bai Xiao is the second batch of students entering the examination room. Previously, ten students in one batch had completed the exam.

Bai Xiao thought for a while and replied: "It's okay, it's not too strict, but the questions asked may be tricky. I was stunned for a moment and thought for a long time before I answered it."

"Ah, that's so miserable. Even you will be stunned for a moment. I will definitely be blank at that time."

Bai Xiao's answer suddenly made the girls around her nervous. Who doesn't know that Bai Xiao is a veritable academic master in the class. Her super hands-on ability and clear thinking are simply the object of learning and imitation for other students. Even she is stunned for a moment, which is really difficult.

Bai Xiao smiled and said, "Don't worry so much. There are also very simple test questions. For example, what Han Ying drew was the test questions for 'gel electrophoresis'. Although it took longer than other experiments, it was better because it was simple to operate and had a higher possibility of passing."

"When it comes to gel electrophoresis, Bai Xiao... can I ask you a question?"

“What’s the problem?”

"That's... I once ran the protein marker and ran away the marker..."

"Ah?" Bai Xiao was stunned for a moment. Marker is actually a combination of several proteins. Because the size of various proteins is clear, multiple bands similar to a ruler will be formed after electrophoresis. Other unknown proteins can be judged by comparing them with marker.

The protein usually runs in the screen made of gel, and it is possible to run in a skewed manner and spread, but it is impossible to run away while running.

"It's really gone." The girl looked puzzled.

"Will there be any problem with the glue you made?"

"I can't do it. I made it bit by bit according to the formula, and there was no violent shock when solidified. The concentrated glue and the separation glue were absolutely uniform. And the other proteins were obviously good, so the marker ran away."

"Did you plug the power in the reverse?" Bai Xiao asked subconsciously, but thinking that other proteins are intact, this possibility can be ruled out. Moreover, she believes that the girl who asks this question should not make such a low-level mistake. Bai Xiao thought about it and the biggest possibility was that the raw materials for making glue or that the marker itself had expired.

She smiled and said, "That's not your operation problem, it may be a raw material problem, don't worry."

"Really?"

"Um!"

"Then I'll be relieved." The girl breathed a sigh of relief and said with a smile, "But I still hope not to get gel electrophoresis, leaving a shadow in my heart."

"Then I wish you to dilute the protein sample and use the microplate reader." Bai Xiao said with a smile.

This type of experiment is relatively not difficult. The main test is students' stable operation. As long as the movement is gentler and no bubbles are blown out, the final measurement value will be passed within a limited range.

"Thank you for your good words." The girl said with a smile on her face.

Talking to Bai Xiao is to make people feel happy. Not only is the face beautiful but the voice sounds nice, but the contents they say are also comfortable.

Bai Xiao waited in the corridor for a while, and the second batch of candidates who entered the exam came out one after another. From their relaxed expressions, Bai Xiao knew that this exam should not have too many problems for them.

In fact, as long as you master the key experimental skills of this type of graduation exam, students will generally pass it. After all, everyone is student-oriented and spends nearly half of the time in the laboratory for the past three years. As you practice various experiments more often, even rotten wood should carve beautiful flowers.

If it still doesn't work, then change careers as soon as possible.

Seeing Han Ying, Cheng Xiaohui, Li Xianbin and the others coming out, Bai Xiao stepped forward to communicate with them. After knowing that they had a successful exam, he smiled, chatted with them for a few words, and then said goodbye and prepared to go home.

The exam continues in the next few days.

With the completion of various experimental courses one after another, it will soon be the turn of regular theoretical courses to take exams.

At this time, the entire Binhe University of Science and Technology officially entered the exam week.

During this period, the school’s library and all-night classrooms became a difficult scene. The candidates who were taking textbooks and exercise books were everywhere for review, which made people feel very moved by everyone’s enthusiasm for learning. How great would it be if this was always in this state of hard work.

From the online search of the examination room where he was in the school, Bai Xiao, like others, then he devoted himself to the intense review and taking exams. Compared with the practical and theoretical answers of experimental courses, the examinations of other courses are completely reflected in the paper. Relatively speaking, there are more objective questions, either black or white, and there is not much room for favoritism and reversal.

What made Bai Xiao happy was that her aunt finally ended before the exam week officially began. She seemed to have gained a new life and became even more brilliant. After all, the psychological pressure on her aunt was still quite heavy, which was far heavier than the physical burden caused.

Once a person's mood is better, he will emit a feeling of sunshine and confidence from the inside out. In this regard, the people around Bai Xiao have the most say. They often see Bai Xiao's long eyelashes, and their clear eyes are as bright as slight ripples in the deep lake. The beautiful eyes and the charm of the flowing eyes are enviable.

"It seems that Bai Xiao should have done a great job in this exam." Li Xianbin, who suffered setbacks in the "Fermentation Project" exam, said in a jealous tone.

But as Bai Xiao looked at him slantedly, he immediately smiled and looked like a dog-licking dog.

Bai Xiao was speechless about this.

Time flies, the tense and busy week passed quickly, and the exam week officially ended. At the same time, the courses that started the exam earlier also announced their results one after another.

Now there are some happy and sad companies. They are happy and happy when they are in the exam. They are busy calling everyone to play games together. However, they are not good at taking the exam and are in a depressed mood. After a brief downturn, they turn around and throw their grades behind and join the team that plays games.

Bai Xiao naturally belongs to the category of good exams. Looking at her score of more than 90 points in each course, she thought she could have a relatively comfortable life this summer vacation.
Chapter completed!
