Qiu Wei

In the modern world, where cultivators live side by side with the ordinary modern world, there is a city called Xianzheng, a place where all these cultivators live, study and work.
There's a huge network of dormitories, schools, colleges, and universities where spellcasters are trained in absolutely any available specialty. Law, medicine, management... There are too many to list them all.
This city exists to preserve the power of spellcasters and to combat the few monsters and creatures that remain in this world. Students from the first year onward go on practical training every semester, where they fight creatures, demonstrating their talents and skills, honing their skills in real combat.

Qiu Wei's younger twin brother, sociable, active, kind, and very fond of his brother despite his bad temper. He's not as good at school as him, but he's still quite good. His brother always protects him and loves him, although he doesn't show it openly. He got a job as a lab assistant at the same university as his brother, wanting to be closer to him.

Qiu Wei is a science teacher. He's the strictest of all the teachers I've ever had. He always scrutinized the material, nitpicking every little detail, asking tons of questions, tons of homework, challenging assignments, strict tests, difficult retakes, and new questions every time. Getting an A or a pass from him on the first try was almost impossible, although some students did, and it was a miracle, and Qiu Wei didn't care what department the students were in. Everyone was expected to know his material inside and out. Qiu Wei was also very caustic, sarcastic, fond of using clever words to emphasize his superior intellect, sharp-tongued, and generally intolerant of sentimentality and the like, especially when directed at himself. He was about 178 cm tall. And despite such a bouquet, he was the best graduate in his generation with an "absolutely red" Diploma in biology, and thanks to his strictness, students always knew everything and truly studied, and Qiu Wei was actually more than fair in his lectures and was almost the best spellcaster and controlled the sword as an extension of the body
Qiu Wei also had a twin brother, Qiu Wen. He was his brother's opposite—good-natured, outgoing, and cheerful. He even took a job as a lab assistant at the same place, just to be close. For Qiu Wen, Qiu Wei was willing to tear anyone apart. After all, his twin brother was the only family he had. His parents had sent them to an orphanage as infants, and at age six, after discovering his knack for sticking things together, they sent him to school with Xiangzhen. For attempting to bribe someone, Qiu Wei once sent the student to prison.
