Scum and Sister

Andingcheng Third Senior High School.

At half-past five in the afternoon, the students have finished their dinner, and there is still an hour until evening self-study begins.

After studying for the whole day, it is a good time to rest and relax. Groups of students can be seen everywhere on campus.

The girls behave similarly, most of them holding hands and walking slowly, whispering softly. Occasionally, they burst into laughter when they see a handsome boy.

The boys are full of tricks. Some walk fast without looking at anything, while others bounce around and speak loudly, but their eyes are always searching for beautiful girls. There are also those who walk through the crowd holding a stack of books with a serious expression on their faces.

The entire campus is brimming with youth and joy. Xie Yao feels nostalgic as it brings back memories for him, but unfortunately, the world he remembers no longer exists.

The temporary campus life of these students is limited by the current environment, and the federal government's main concern is to ensure that children can complete high school without any worries. This was the teaching of a sage during the founding of the Federation: "Only children who grow up under the care of human beings dare to fight for the cause of mankind."

Therefore, most students will not face much trouble until they reach adulthood at the age of 18. They learn about the dangers and evils facing humanity from textbooks, newspapers, and others. Despite the warnings, most freshmen still fail to realize that they still have three carefree years left.

After high school, they will either enter various industries in society and begin to worry about making money, or they will pass the cultural course exam and get a decent job in the Ministry of Urban Defense, Public Security Bureau, Ministry of Engineering, or other public offices. Many positions also have grade requirements for physical skills assessments.

Universities, which can be found in every state and city, are only open to the elite with real talent. They need to have excellent results in cultural courses or have talents, absorb potions, or achieve outstanding results in physical skills.

Therefore, the only real happiness on campus is for the first and second-year high school students. Senior high school students feel the pressure increase, such as hurrying back to the classroom from the cafeteria, holding their lunch boxes with their heads down, preparing to study without wasting any time to eat.

Xie Yao recognized that this was a student in his class.

As a qualified teacher, remembering the names of the students in the class is a must.

Of course, this is limited to more distinctive features.

For example, being very beautiful, talented, or having very good or bad grades.

Seeing that she was about to hit the wall without raising her head, Xie Yao called out, "Hu Lan."

"What?"

Hu Lan is small and thin, as if she could be blown away by a gust of wind.

Hearing someone calling her, she paused and raised her head blankly, suddenly showing a surprised expression, slightly judging:

"Thank you, teacher!"

"Well, watch the road," Xie Yao said.

"Okay, thank you teacher for reminding!"

Hu Lan replied excitedly, feeling excited inside.

Among the classmates, this new potion teacher is very popular, of course, only among the girls.

After all, he speaks calmly and absent-mindedly, and his classes are interesting, especially for the young male teacher who looks quite outstanding. They don't know how he's better than the old man before.

But the next moment, Xie Yao suddenly showed a hint of cunning:

"I heard that five people in your class failed the unified cultural exam last week, including you."

Hu Lan suddenly collapsed and said, "Teacher, why are you doing this...I, I have been working hard to review. You see, I am studying during all my meals! But it's really boring."

This is true. The courses in the third year of high school are divided into three categories: physical exercises, potions, and culture.

Potions class and physical exercise class are limited by the shortage of teachers. Generally, more than two classes are combined, and one teacher is responsible for at least four classes.

Culture class is very powerful. According to the class and subject, different teachers are responsible for different classes.

It has five main courses: "Geography", "Chinese", "Society and History", "Mathematics", "Conventional Material Theory", and the daily learning tasks are quite heavy.

As for "Potion Theory" in Potions Class and "Acupoint Notes" in Physical Skills Class, they also contain educational content. However, the former is mainly covered in experimental courses, while the latter requires manual guidance from the physical skills teacher, and thus, is not included in the basic cultural curriculum.

Xie Yao is only a class teacher, not a cultural teacher, so he only mentioned the results of cultural classes. Seeing the little girl crying after being poked at the pain point, he smiled and comforted her:

"Don't worry, just practice more. Practice makes perfect. In addition, your understanding of the theoretical basis of potions is quite good."

Hu Lan smiled and asked, "Teacher, what are you going to do with these ingredients?"

Due to her nearsightedness, she only noticed now that Xie Yao was carrying a well-packed, transparent long bag filled with water containing huge fishes. It was about half a meter long with a fat head. Although the fish eyes were not turned white, it did not seem to have an aura, and she didn't know whether it was dead or alive.

Xie Yao explained, "It's a contaminated fish, and it's tomorrow's experimental class prop. Since you're so interested, I'll let you come on stage to observe and explain closely, and test your theoretical understanding."

Hu Lan was anxious and replied, "Teacher, this opportunity is still..."

But Xie Yao didn't give her a chance, nodding briefly before quickly walking towards the laboratory building.

Hu Lan stood there blankly, her eyes sluggish. She finished the second half of her sentence aggrievedly: "...Leave it to others."

Anding No. 3 High School's laboratory building is located in the southeast of the school. It has three buildings and is huge in scale, far better than the laboratory buildings of the first and second high schools.

Thanks to Principal Zhang Qiren, the laboratory building was expanded once and renovated twice to achieve this scale.

Here, newly recruited Potions teachers will be assigned their own laboratory after passing the assessment for one year.

Xie Yao is still a newcomer, and the school has arranged for another teacher to mentor him, so Xie Yao is considered an assistant to that teacher and has gained valuable experience.

Laboratory Building 2, Building 204, occupies the entire 4th floor and one whole floor belongs to Xie Yao's mentor.

Xie Yao stops at the door and looks at the metal box on the door.

The laboratory equipment, monster specimens, etc. in the laboratory are of great value, so the school's laboratories have spent a lot of money to purchase code locks.

The code lock is exquisite in style and looks expensive.

As a member of the laboratory, Xie Yao knows the code to open the door.

However, he does not choose to open the door directly but bends down and taps gently.

"Tuk-Tuk-Tuk."

After waiting for three seconds and receiving no response from inside, Xie Yao stretches out his palm and knocks on the door with a bit more force.

"Boom! Bang! Bang!"

For a while, there is a female voice that is magnetic but obviously suppressing anger:

"...Idiot! Come in by yourself, the door is unlocked!"
