What’s the point of cultivating immortality if you don’t have money?

Hearing Zhang Yu's answer, a gleam flashed in Black Crow's eyes, and he laughed, "Haha, if it's the Spring and Autumn Endless Zen, then many old folks would love to learn it, a top-tier body refining technique they'd want to complete."

"Then I wish you success in this trial lesson, Teacher Ma, and that you become the new golden teacher of our gang."

"Once you become a golden teacher, you'll be able to teach the most important, wealthiest clients in the gang, the ones with the strongest spending power. A post-tax income of over a million each month will definitely not be a problem."

"Oh, right, there are also three senior teachers from the gang here to try out the lesson…"

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

Three gang teachers were already waiting there. When they saw Black Crow and Zhang Yu walking over, they couldn't help but take a few extra glances, a hint of doubt flashing in their eyes.

One of the middle-aged women asked curiously, "Black Crow, who is this?"

Black Crow introduced, "This is Teacher Ma Yunteng, also here to participate in today's trial lesson."

Hearing this, the three gang teachers all frowned, and their gazes towards Zhang Yu held an even stronger sense of coldness and hostility.

The middle-aged woman directly inquired about Zhang Yu's background, asking, "I know all the teachers in the gang who can tutor those at the peak of Qi Refining. This Teacher Ma seems a bit unfamiliar. Could it be that you've only recently joined the gang?"

Black Crow smiled slightly and said, "Teacher Ma hasn't been here for long. He was previously responsible for teaching construction site cultivation techniques. He hasn't been around for the past few months due to some matters, so it's normal that Teacher Ci doesn't recognize him."

Hearing that Zhang Yu originally taught construction site cultivation techniques, a trace of contempt flashed in the hearts of Teacher Ci and the other two.

After all, the average education level of construction workers is low, their Immortal Dao foundation is poor, and because they take inferior drugs year-round, there are far more mentally challenged individuals than in other classes.

It can be said that the quality of students in the construction site class is far inferior to that of the elderly class, and their spending power is even more incomparable.

And the teachers who teach the construction site class are naturally much worse in terms of strength, teaching ability, and mastery of cultivation techniques compared to the three of them.

Teacher Ci nodded and didn't pay any more attention to Zhang Yu. It seemed that her opponents today were still the other two senior underground teachers beside her.

Black Crow looked at his phone and said, "The elders of the gang have all arrived and are watching the classroom through the cameras."

"Then I'll greet the students in the class first, and then we'll start the trial lesson."

"The order will be as previously arranged, with the three of you, Teacher Ci, going first, and then Teacher Ma will go last. Is that okay?"

Zhang Yu nodded, indicating that there was no problem.

Black Crow walked into the classroom and saw more than a dozen old men with different temperaments already waiting in the classroom, some standing and some sitting.

As these dozen or so old men with different temperaments all looked over, feeling the pressure of so many at the peak of Qi Refining, Black Crow's footsteps faltered, and cold sweat trickled down his forehead.

Black Crow smiled slightly and said, "Sorry to keep you all waiting, our trial lesson will begin immediately. Thank you all very much for taking the time…"

At this moment, a stern-faced, silver-haired old man in the audience said coldly, "Black Crow, last time that Teacher Song only had a high school diploma. He didn't even pass the university entrance exam, yet he dared to come and teach us."

"The teachers you've arranged this time, won't they be just as unreliable?"

Black Crow quickly reassured, "Mr. Wang, although Teacher Song only has a high school diploma, he has extensive teaching experience. A low education level doesn't affect his ability to teach…"

Mr. Wang snorted and said, "Who sitting in this classroom isn't a university graduate? Can a high school student teach us? Can he teach clearly?"

Black Crow wiped the sweat from his forehead. He understood that these university-graduated old men in front of him had been able to cultivate, study, and work to this age, and were able to maintain their spending through their work. They were all elite workhorses in their companies, absolute education level discriminators. Whether high school graduates should have human rights in their eyes might even be questionable.

At this moment, another old man chimed in, "Is your Dark Learning Gang even competent? If it were in our company, resumes with high school diplomas wouldn't even reach my desk. Are they even qualified to teach people?"

Yet another old man agreed, "Aren't people who don't pass the university entrance exam just social scum? Their evolution isn't even complete, and their bloodline is destined to be eliminated…"

"That's right!" An old woman with disheveled hair and beard said, "Can someone who doesn't pass the university entrance exam even be considered a person?"

"Not necessarily, everyone, not necessarily," Black Crow quickly tried to dissuade them. "Moreover, the teachers for our trial lesson this time are guaranteed to be university graduates."

"Hmph," Mr. Wang said, "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 moment of difficulty. After all, almost all the teachers in the gang hid their identities and were unwilling to have their information known. How could they possibly provide university diplomas?

Moreover, he had just said it casually, and he wasn't even sure if the four trial lesson teachers today were all university graduates.

Black Crow, who had a high school education, couldn't help but curse in his heart, "These old bastards, none of them treat high school students as human beings."

"You should know that good high schools are no worse than vocational colleges, and good vocational colleges are no worse than universities, so excellent high school graduates can fully be competent as teachers after years of hard work…"

Although he secretly grumbled in his heart, he didn't dare to offend these important clients.

Just as Black Crow was secretly thinking about the trouble, his phone vibrated. It was a message sent to him by the gang elders watching the classroom through the cameras.

After reading the contents, Black Crow said to the old men in front of him, "Everyone, the dark tutoring world doesn't arbitrarily reveal identities. This is a long-standing rule of the underworld, and our Dark Learning Gang shouldn't break it."

"However, your concerns are also reasonable. How about we change the method and have you send a representative to personally verify the teacher's cultivation level?"

Mr. Wang frowned and asked, "How to verify?"

Black Crow said, "This time, they are all teachers responsible for teaching body refining. Why don't you, Mr. Wang, take action? Each teacher will not block, parry, or dodge, but will use their physical body to withstand three of your moves. What do you think?"

"With your level, Mr. Wang, a teacher who can withstand your three moves like that definitely won't only have a high school diploma, right?"

The crowd nodded slightly. After all, high school students can't pass the university entrance exam. As soon as they graduate from high school, they have to work, and they have absolutely no time, energy, or wealth to meticulously cultivate various body refining techniques.

Only university students go to the second level, where they can continue to focus on their studies and cultivate more techniques during their ten years of university.

Even if they both have a physical body strength of level 10, people with a university education often far outperform people with a high school education in various aspects with the blessing of multiple body refining techniques.

Mr. Wang said proudly, "Hmph, those wastes who haven't even gone to university can't possibly withstand three of my moves."

"I approve of this method."

Black Crow knew that this Mr. Wang was quite prestigious among these old things. As expected, seeing him agree, the other old men had no further objections.

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

Although Zhang Yu wasn't very clear about what Mr. Wang's strength was, he had no choice but to agree for the time being.

That slight hesitation of his, in the eyes of Teacher Ci and the other two, was a sign of insufficient confidence. They became even more contemptuous of Zhang Yu and even suspected that Zhang Yu only had a high school diploma, which was why he was so hesitant.

Teacher Ci, the middle-aged woman, was the first trial lesson teacher to enter the classroom.

When verifying her cultivation level, she stood still, allowing Mr. Wang to strike her shoulders and stomach with three consecutive palms.

Amidst the three loud booms, Teacher Ci took five steps back, her face flushed for a moment, before returning to normal in the blink of an eye.

Mr. Wang nodded in approval, "Not bad, physical body strength has reached its peak, possesses multiple body protection techniques. Only university graduates have this level."

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

"Today, I'm going to teach everyone how to poop."

"This may seem like a daily trivial matter, but there's a lot of knowledge in it, concerning the safety of your life."

"Many years ago, a senior expert, after working overtime for ten years without rest, suffered from constipation for half a year due to excessive pressure. He eventually comprehended a set of techniques on the toilet, called the Detoxification and Health Cultivation Technique."

"What I'm going to teach today is this Detoxification and Health Cultivation Technique. After mastering it, you can excrete toxins and impurities from your body every day…"

"The way of body refining, three parts practice, seven parts eating, and the remaining ninety parts all depend on how you jab medicine."

"As the saying goes, the more needle holes on your arm, the worse your grades will be."

"But the more medicine you jab, the more you need to detoxify, so there's another saying called good students must be able to squat…"

"According to the latest research in Immortal City, there is a positive correlation between students' body refining scores and hemorrhoid rates…"

Looking at the old men listening attentively to her lecture, Teacher Ci's motivation grew stronger and stronger.

She thought to herself, "For my nine children, to raise them to adulthood, to get them into university, to enable them to find jobs, I must become a golden teacher!"

Whenever she thought about her nine children growing up, working hard to repay her parenting loans, and transferring money to her every month, Teacher Ci felt that she was getting closer and closer to the wonderful days of not having to work overtime and only having to work 12 hours a day.

…

At the same time, the cameras in the classroom captured Teacher Ci's classroom performance, allowing the many elders of the Dark Learning Gang sitting in the conference room to see clearly.

One of the elders commented, "Little Ci's set lacks innovation and has no tricks."

Another elder said, "The course is solid, but it's old news. The renewal rate is probably not high."

"Let's look at the next one."

…

Outside the classroom, Zhang Yu listened to Teacher Ci's lecture and thought to himself, "Simple to understand, key points highlighted, memorable, and humorous, combined with the latest theories… This woman's lecturing level is already about the same as an excellent teacher in a key high school, right?"

"The competition for the golden teacher of this Dark Learning Gang seems to be more intense than I imagined."

"No, my original preparations are still somewhat insufficient, I need to add more chips."

"This woman's flaw lies in this Detoxification and Health Cultivation Technique… This technique is not advanced enough."

"I have to highlight the advantages of Spring and Autumn Endless Zen in terms of taking medicine!"
