Chapter Seven: Farewell to the Departed Soul

  But when Zhan Fei burst out laughing, countless eyes were fixed on him, and both Guo Xin and Zhou Tai secretly wiped away sweat for Zhan Fei. This was Hei Mian's class after all, and Hei Mian always had a dark face. Many students in the class were terrified of Hei Mian. Yet, Zhan Fei dared to laugh loudly during Hei Mian's most intense lecture, which was simply pushing Hei Mian's patience to the limit!

  After 7 or 8 seconds, Zhan Fei found that the noisy classroom suddenly became quiet. Everyone was looking at him, and then he looked up at the platform, Hei Mian had also stopped teaching, with his hands behind his back, looking at Zhan Fei with great interest.

  This time, Zhan Fei finally knew what he had done, and hurriedly collected the smile on his face, carefully looking at Hei Mian, who also slowly opened his mouth and said: "This classmate, I want to ask you, is my lecture so funny?"

  Zhan Fei knew that this was the prelude to a storm, and he immediately stood up straight and said: "Sorry teacher, I was momentarily excited, please forgive me!"

  Hei Mian listened and said: "A moment of excitement? Can you tell me, what's the method for being excited?"

  Hei Mian said, holding the blackboard eraser and then slapping it on the table. Normally, Xuan Fei's body would have jumped in fright like the table, but this time he wasn't afraid. All students who are afraid of teachers are poor students!

  All excellent students are the focus of teachers' care, and their treatment is different from that of poor students. Zhan Fei had experienced the treatment of an excellent student before coming to university, and he also experienced the treatment of a poor student after coming to university. Before, he was a poor student, so when facing Teacher Hei Mian, he would be scared and tremble with fear.

  But now that his intelligence has skyrocketed, he can proudly say a sentence: I will be an excellent student! Facing the teacher, it's only natural that he's not afraid anymore. In fact, what Hei Mian said earlier was written on the blackboard, and Zhan Fei just took a glance to see everything clearly.

  Originally, his eyes were slightly nearsighted, and sitting in this position, it was not easy to see the blackboard clearly. However, with a slight increase in agility, Xiang Fei's vision had also returned to normal, which is why he could see so clearly now.

  And then, Zhan Fei spoke up: "Because the derivation of that coordinate parameter equation is really interesting, I didn't understand before why the point-to-line vector parameter of line L would be..."

  Next，展飞却是将黑板上黑面正在讲的一个难点十分流利的说了一遍，这个难点黑面是准备拿两节课去讲的，因为这个知识点，对于立体思维能力和逻辑推导能力都有着极高的要求，学生们掌握起来极难。

  Next, Zhang Fei fluently explained a difficult point that Hei Mian was about to explain on the blackboard, which Hei Mian had planned to spend two lessons teaching. This knowledge point has extremely high requirements for spatial thinking ability and logical reasoning ability, making it extremely difficult for students to grasp.

  Even if it's just memorization, most students find it difficult to grasp, and this knowledge point is both a difficulty and a key point, so he's prepared to spend a whole lesson on it. The smile from Zhan Fei earlier had indeed made Hei Mian very angry. If Zhan Fei can't come up with a reasonable explanation, then he's also prepared to make an example out of him, deducting points from his usual score.

  After all, if Zhan Fei had listened attentively to the class, it would have been fine. He stood high on the podium and could see far, so he knew about Zhan Fei's performance throughout the lesson, which was basically either daydreaming or sleeping. However, he did not expect that this student's answer would be completely beyond his expectations.

  This poor student has thoroughly understood and grasped this knowledge point. To think that even now, the best student in the entire department, Xu Jiaorong, is still completely baffled and hasn't been able to understand it!

  But Zhan Fei had already understood and grasped it, he could understand that when people learning math get stuck on a difficult problem and then suddenly solve it, the excitement and thrill are indeed hard to suppress, bursting into laughter is also justified.

  What surprised Hei Mian even more was that Zhan Fei explained this difficult point in a way that was easy to understand, using his own words. The process of explanation was even better than the one by his professional instructor.

  At least, after Zhan Fei finished speaking, many students who were still confused showed a sudden look of clarity. The teacher, Hei Mian, also greatly changed his opinion of Zhan Fei, thinking that he was a genius student!

  No matter which teacher, for a genius student, they all have an extremely friendly attitude. As for the situation where Zhan Fei fell asleep and was distracted before class, it was completely ignored by Hei Mian. When he slept and was distracted, he had already analyzed the difficult points that you couldn't figure out in half a day. Does this kind of student need to study as diligently as an ordinary student?

  Geniuses should be treated specially, so next, Heimian spoke up and said: "You're speaking very well, what's your name, classmate?" Zhan Fei heard this, was stunned for a moment, before opening his mouth to say: "I'm Zhan Fei, teacher."

  "Alright, Zhang Fei, take a seat."

  While Zhang Fei listened, he also sat down. At this moment, his classmates were all staring at him in surprise. What kind of role was Zhang Fei? Who didn't know? He had never seriously listened to a lesson before, and every exam was always copied, but such a difficult knowledge point, he actually grasped it so quickly?

  Even Han Qing, the big sister of the Han family, who was sitting next to Zhan Fei, temporarily forgot about Zhan Fei's previous lewd behavior and looked at him with a surprised gaze. Zhou Tai, on the other hand, stared at Zhan Fei carefully before opening his mouth and saying: "You little brat, what kind of magical medicine did you eat? How did you suddenly become so powerful?"

  Zhan Fei listened and said: "What do you know? My brother is usually just a bit low-key, but actually my brother is a very awesome person!"

  Zhou Tai listened and directly patted Zhang Fei's arm, saying: "Cut it out!"

  Because of the explanation before class, Hei Mian originally planned to spend two classes on a key and difficult point, but finished it in one class, with an effect much better than he had expected. In the second class, Hei Mian directly assigned a question, letting everyone try to apply the knowledge point from the previous class.

  After all, understanding and grasping are two different concepts. Hei Mian also wants to strike while the iron is hot, letting everyone thoroughly grasp this knowledge point. Such a simple question, Zhan Fei glanced at it and threw it aside. For him, doing this question was as easy as 1+1=?. He didn't even bother to lift a finger, naturally he wouldn't deign to do it.

  As for Zhou Tai and others, like Zhan Fei, they also threw the question to one side and played with their mobile phones. Of course, it wasn't that they were too proud to do it, but rather they simply didn't know how to do it. In Zhan Fei's major, there were more boys than girls, and compared to the boys, most of the girls were more obedient and well-behaved.

  Han Huan was the same, tilting his head, biting the pen cap, and constantly thinking in his mind to find a way to solve it. However, this question is not easy to do for the time being, so after twenty minutes, Han Huan still had no clue.
