Putting down the pen he was using to take notes, Gu Xinghe rubbed his temples.

His excellent memory and learning abilities enabled him to master the knowledge in these textbooks in a short period of time.

However, this can only be considered "cramming" self-study, where you first memorize and basically master all the knowledge and content.

In terms of in-depth application of knowledge and teaching skills, Gu Xinghe admits that he is definitely not as good as a real mathematics professor.

However, if he uses the [Domain] skill of Touch of the Mist as an auxiliary, he can use some mental suggestion to influence the students present.

Gu Xinghe felt confident that he could fool them without anyone noticing anything amiss.

Moreover, the term "fooling around" is used because mathematics is the most outstanding subject at St. George's University.

If it were an ordinary university, Gu Xinghe would feel that his current knowledge reserves were more than enough.

Looking at the new skill called "Advanced Mathematics [LV.10]" that appeared on his player panel.

Gu Xinghe was very happy.

Especially when he heard the discussions from his viewers in his live stream—

[Impossible! This is absolutely impossible!]

[How is it possible for someone to understand so many math books in less than half an evening?!]

At this moment, Gu Xinghe's smile widened even further, and his mood became even more cheerful.

After preparing the textbooks needed for tomorrow's classes, Gu Xinghe lay down on his bed in the dormitory and fell asleep peacefully.

The next morning.

Gu Xinghe left the dormitory with course materials, student rosters, and other relevant documents.

But when he arrived at the classroom a little early, he found that the students had arrived even earlier than him.

The moment Gu Xinghe walked into the classroom, the previously noisy classroom suddenly fell silent.

The students all craned their necks, eagerly watching Gu Xinghe's figure slowly walk into the classroom.

When they saw Gu Xinghe walk in, they felt that their professor seemed somewhat different from yesterday.

This change is very subtle and is not a change in appearance.

Rather, it's a change in personal temperament and attitude towards them.

Although in the eyes of all the students present, Gu Xinghe yesterday possessed a mysterious and refined scholarly air.

But compared to being a "small" math professor.

However, everyone felt that Gu Xinghe's scholarly demeanor did not come from his research in mathematics.

His research is not focused on a single basic discipline, but rather on something much grander and more expansive.

But now, the students present all felt that Gu Xinghe's temperament had undoubtedly changed.

It's as if he's undergone a "consumption downgrade," and at this moment he undoubtedly looks more like a frail mathematics professor.

Moreover, they all felt that Gu Xinghe's attitude towards them seemed to have become more intimate.

Such subtle changes are obviously not something everyone can notice.

At least the students present felt that this was because Gu Xinghe had given them a great lecture.

This made them closer to him, so that those present could also discover it.

At that moment, all the students present felt a strong sense of excitement and a gentle, flowing emotion.

It was as if Gu Xinghe had "downgraded" himself in a way so that they could feel more comfortable.

At that moment, the students felt as if they were a little closer to their revered professor.

They even showed a gratified smile on Gu Xinghe's face now, as if they were witnessing their own growth.

To this, Gu Xinghe, who was quietly listening to their thoughts, only wanted to say—

The change in his demeanor was simply because he had studied more than ten math textbooks overnight.

The change in the students' attitudes was simply because he had gained a general understanding of the people present through the student roster.

Unlike yesterday, he was no longer a complete stranger to everyone present.

In this light, his decision yesterday to stop "expanding the scope" was indeed the right one.

He had only briefly opened up the domain at that time.

In the minds of the students who listened to his lectures at the time, what he taught had become the truth of the world.

Moreover, seeing the state of these students today, Gu Xinghe felt that he could not further intensify their Dihua mentality.

A faint black mist reappeared in the classroom.

However, the kind of spiritual pollution-like implication it exuded was undoubtedly much weaker than yesterday.

And when the fog once again enveloped the entire classroom.

Gu Xinghe noticed that Field, who was sitting in the back row of the classroom, seemed to sense something and his body trembled slightly.

At that moment, his eyes met Gu Xinghe's quickly, and a satisfied smile appeared on his face.

However, he quickly returned to normal and behaved no differently from the students next to him who were listening attentively and respectfully.

Compared to Gu Xinghe's very "aggressive" use of his domain influence yesterday, this felt more like a kind of "brainwashing" style of teaching.

His classroom teaching today undoubtedly seemed much more normal.

At this moment, he was only using his domain to provide "support," making everyone feel that today's lesson was as amazing as yesterday's.

And he did not cause the students present to misunderstand what he was teaching.

To put it simply, although he did teach yesterday, he mainly relied on students to learn and understand on their own after class.

But today, he is the one who is primarily responsible for teaching.

He simply added a "domain buff" that made everyone think he was an excellent teacher.

His teaching is no longer just reading from the textbook like yesterday; it now includes student questions and answers, as well as blackboard writing.

It can be described as an excellent classroom model full of teacher-student interaction and a good teaching atmosphere.

At this moment, Gu Xinghe put down the chalk in his hand, patted the chalk dust off his fingers, and finally ended today's lesson.

But Gu Xinghe looked like he was about to leave get out of class.

The students in the classroom, however, all began trying to persuade Gu Xinghe to stay.

"Professor, please continue your lecture!"

"Yes, Professor, we'd like to hear more of your lectures!"

At this moment, the students, focused solely on their studies, were no different from the audience members at a concert who kept shouting "encore."

Moreover, Gu Xinghe also realized at this moment that what was in front of him now was—

It turned out to be a group of students who almost never wanted the teacher to extend the class time.

Looking at the group of students in front of him who admired him so much and didn't want him to leave.

Gu Xinghe felt as if he were dreaming back to his days working at the Misfortune Tavern.
