Hearing Zhang Yu’s answer, Black Crow’s eyes gleamed as he chuckled, “Haha, if it’s the Spring Autumn Endless Meditation, that’s a top-tier body refinement technique many elders want to learn and master.”

“Then I wish you success, Teacher Ma Yunteng, in this trial lesson. I hope you become our gang’s new golden-tier teacher.”

“Once you become a golden-tier teacher, you’ll teach our most important, wealthiest, and highest-spending clients. Earning over a million a month after tax will be absolutely no problem.”

“Oh, and by the way, three senior teachers from within the gang will also be participating in this trial lesson…”

As he spoke, Black Crow led Zhang Yu to the classroom where the trial lessons would be held.

Three gang teachers were already waiting there. When they saw Black Crow and Zhang Yu approaching, they couldn’t help but glance at them curiously, a hint of doubt in their eyes.

One of them, a middle-aged woman, asked curiously, “Black Crow, who is this?”

Black Crow introduced, “This is Teacher Ma Yunteng, and he’s also here for today’s trial lesson.”

Hearing this, the three gang teachers all frowned in unison, their gazes at Zhang Yu turning colder and more hostile.

The middle-aged woman immediately started probing Zhang Yu’s background, asking, “I know all the teachers in the gang who can coach peak Qi Refinement practitioners. This Teacher Ma seems unfamiliar. Has he perhaps just joined the gang recently?”

Black Crow, standing to the side, smiled slightly and said, “Teacher Ma hasn’t been with us for long. He was previously in charge of teaching construction site techniques, and he’s been away for a few months recently, so it’s perfectly normal for you not to know him, Teacher Ci.”

Upon hearing that Zhang Yu had originally taught construction site techniques, a hint of disdain flashed in Teacher Ci and the other two’s hearts.

After all, construction workers generally have lower average education levels, weaker foundational immortal cultivation, and due to years of taking inferior drugs, there are significantly more individuals with intellectual disabilities compared to other classes.

One could say that the quality of students in the construction worker classes is far inferior to that of the elderly classes, and their spending power pales in comparison.

Consequently, teachers who taught construction worker classes naturally had much lower standards. Their strength, teaching ability, and mastery of techniques were often far inferior to those of the three teachers present.

Teacher Ci nodded and dismissed Zhang Yu from her thoughts. Her true rivals today, it seemed, were still the two other senior underground teachers beside her.

Black Crow checked his phone and said, “The elders of the gang have all arrived and are watching the classroom via camera.”

“Then I’ll greet the students in the class, and we can begin the trial lesson.”

“The order will be as previously arranged: Teacher Ci and the two of you will go first, and then Teacher Ma will go last. Is that acceptable?”

Zhang Yu nodded, indicating that it was acceptable.

Black Crow entered the classroom and saw over a dozen elders, each with a distinct demeanor, already waiting, some standing, some seated.

As these dozen-plus elders, each with a unique aura, turned to look at him, Black Crow felt the pressure of so many peak Qi Refinement cultivators bearing down. He paused, a bead of cold sweat trickling down his forehead.

Black Crow managed a slight smile and said, “I apologize for the wait, everyone. Our trial lesson is about to begin. Thank you very much for taking the time…”

Just then, an unsmiling elder with a full head of silver hair from the audience coldly stated, “Black Crow, last time, that Teacher Song only had a high school education and hadn’t even gone to college, yet he dared to come and teach us.”

“Are the teachers you’ve arranged this time not going to be so unreliable again?”

Black Crow quickly tried to appease him, “Elder Wang, while Teacher Song only had a high school education, he had extensive teaching experience. A slightly lower academic background doesn’t affect his ability to teach…”

Elder Wang snorted coldly and said, “Who in this classroom isn’t a university graduate? Can a high schooler teach us? Can he even teach clearly?”

Black Crow wiped the sweat from his forehead. He understood that these university-educated elders, who had cultivated, studied, and worked their way up to this age, and could maintain their spending power through their work, were all elite workhorses in companies – absolute academic snobs. In their eyes, whether someone with just a high school diploma even deserved human rights was probably a question mark.

Just then, another elder chimed in, “Is your Dark Study Gang even competent? If this were our company, resumes from high school graduates wouldn’t even reach my desk. Do they really qualify to teach people?”

Yet another elder agreed, “Aren’t people who haven’t even gone to university just social scum? Their evolution isn’t even complete; they carry bloodlines that will eventually be eliminated…”

“Exactly!” exclaimed an old woman with wild hair. “Those who can’t get into university—can they even be considered human?”

“It’s not that extreme, everyone, really,” Black Crow quickly tried to reassure them. “And I assure you, all the teachers for this trial lesson are university graduates.”

“Hmph,” Elder Wang scoffed, “Then we want to see their university diplomas. Only those with university diplomas are qualified to teach here.”

Hearing this, Black Crow’s face showed another hint of awkwardness. After all, almost all the teachers in the gang concealed their identities and were unwilling to have their personal information known. How could they possibly provide university diplomas?

Furthermore, he had just said that casually and wasn’t even sure if all four trial teachers today were actually university graduates.

Black Crow, a high school graduate himself, couldn’t help but curse inwardly, “These old fogeys, not a single one of them treats high schoolers like human beings.”

“One should know that good high schools are no worse than junior colleges, and good junior colleges are no worse than universities. So, excellent high school graduates, after years of hard work, can be perfectly competent as teachers…”

Although he grumbled inwardly, he dared not offend these important clients.

Just as Black Crow was silently fretting, his phone vibrated. It was a message from the gang elders, who were observing the classroom via camera.

After reading the message, Black Crow addressed the elders before him: “Everyone, in the world of underground tutoring, one doesn’t freely disclose their identity. This is a long-standing unwritten rule, and our Dark Study Gang cannot easily break it.”

“However, your concerns are also valid. How about we try a different approach? You could send a representative to personally verify the teachers’ cultivation levels?”

Elder Wang frowned and asked, “How will you verify it?”

Black Crow replied, “Since all these teachers are responsible for teaching body refinement, how about you, Elder Wang, take action? Each teacher will stand firm, without blocking, dodging, or resisting, and endure three of your strikes with their bare body. What do you think?”

“Given your level, Elder Wang, any teacher who can withstand three of your blows like that surely wouldn’t have just a high school education, would they?”

The crowd nodded slightly. After all, high schoolers who didn’t get into university had to start working right after graduation, leaving them with no time, energy, or wealth to extensively refine various body cultivation techniques.

Only university students, going to the second level, could continue to focus on their studies and cultivate more techniques during their ten years of university life.

Even with the same level 10 physical strength, university-educated individuals, bolstered by multiple body refinement techniques, often significantly outperformed those with only a high school education in various aspects.

Elder Wang declared proudly, “Hmph, it’s certainly impossible for those wastes who haven’t even attended university to withstand three of my strikes.”

“I approve of this method.”

Black Crow knew that Elder Wang held considerable prestige among these old individuals. As expected, once he agreed, the other elders raised no further objections.

So, Black Crow stepped out and explained the situation to Zhang Yu and the other three teachers. The other three teachers, full of confidence, agreed without hesitation.

Although Zhang Yu wasn’t entirely sure of Elder Wang’s strength, given the situation, he had no choice but to agree for now.

However, his slight hesitation was perceived by Teacher Ci and the other two as a lack of confidence. They became even more disdainful of Zhang Yu, even wondering if his hesitation stemmed from having only a high school education.

Teacher Ci, who appeared as a middle-aged woman, was the first trial teacher to enter the classroom.

During the cultivation verification, she stood still, allowing Elder Wang to strike her three times in a row, hitting her on both shoulders and her abdomen.

Amidst three loud thuds, Teacher Ci stumbled back five steps. Her face flushed crimson for a moment before quickly returning to normal.

Elder Wang nodded approvingly: “Good. Peak physical strength, possessing multiple body-protection techniques. Only university graduates have this level.”

Having gained the elders’ approval, Teacher Ci secretly breathed a sigh of relief and walked to the podium to begin her lesson.

“Today, I’m going to teach you how to defecate.”

“This may seem like a mundane daily task, but there’s a profound wisdom to it, one that concerns your very life.”

“Years ago, a senior master, after ten years of non-stop overtime, suffered from half a year of constipation due to excessive stress. Ultimately, while on the toilet, he comprehended a set of techniques called the ‘Detoxification and Health Preservation Technique’.”

“Today, I will teach you this ‘Detoxification and Health Preservation Technique’. Once mastered, it allows you to expel toxins and impurities from your body daily…”

“In the path of body refinement, three parts are practice, seven parts are diet, and the remaining ninety parts depend on how you inject your medicine.”

“As the saying goes, ‘Many needle marks on the arm, and your results won’t be bad.'”

“But the more medicine you inject, the more you need to detoxify. That’s why there’s another saying: ‘A good student must be able to hold it in…'”

“According to the latest research from Xian City, there’s a positive correlation between students’ body refinement achievements and their hemorrhoid rates…”

Watching the elders listen intently to her lecture, Teacher Ci felt her motivation grow stronger and stronger.

She thought to herself, “For my nine children, to raise them to adulthood, to get them into university, and to help them find jobs, I must become a golden-tier teacher!”

Whenever she imagined her nine children growing up, working hard to pay off her upbringing loan, and transferring money to her every month, Teacher Ci felt herself getting closer to the wonderful days of not needing to work overtime, only having to work 12 hours a day.

Meanwhile, cameras in the classroom captured Teacher Ci’s performance, allowing the Dark Study Gang elders, who were seated in the conference room on the other side, to observe everything clearly.

One of the elders commented, “Teacher Ci’s routine lacks innovation; it doesn’t have much flair.”

Another elder remarked, “The lesson is solid enough, but it’s old news. The re-enrollment rate probably won’t be high.”

“Let’s see the next one.”

Outside the classroom, Zhang Yu listened to Teacher Ci’s lecture and thought to himself, “It’s profound yet easy to understand, highlights key points, full of memorable details, and even lighthearted and humorous, incorporating the latest theories… This woman’s lecturing skill is almost on par with an excellent teacher from a top high school, isn’t it?”

“The competition to become a golden-tier teacher in this Dark Study Gang seems more intense than I imagined.”

“No, my original preparations were still insufficient. I need to add more leverage.”

“This woman’s flaw lies in this Detoxification and Health Preservation Technique… This technique isn’t advanced enough.”

“I need to highlight the advantages of the Spring Autumn Endless Meditation when it comes to taking medicine!”
