Within the desolate, unfinished building, Zhang Yu stood silently in the vast hall, his mind replaying the effects of his Excavating Palm technique reaching level 10.

“With a single palm strike, my control over the ‘Excavating Force’ has deepened, the area I can ‘excavate’ seems to have doubled,” Zhang Yu mused, extending his palm again. The ‘Excavating Force’ stirred the air with whistling sounds as it advanced slowly.

“This Excavating Palm can unleash tremendous power, but the preparatory movements are too extensive, the actions slow and lacking agility. Truly, it’s unsuitable for combat.”

“Without the construction site, its utility is limited,” Zhang Yu shook his head with resignation. He already knew these seemingly ordinary techniques wouldn’t significantly boost his college entrance exam scores.

“Very well, sharpening the axe doesn’t delay the woodcutting. As long as it helps me earn more coin, spending some time cultivating these martial skills is acceptable.” However, now that Excavating Palm had reached level 10, Zhang Yu naturally wouldn’t invest more effort into it. And since the Feathered Tome’s cooldown hadn’t ended, he shifted his focus to cultivating the level 10 Crimson Marrow Primordial Qi, striving to enhance his physical fortitude.

In the blink of an eye, five days passed. During these five days, Zhang Yu not only mastered Excavating Palm and Racing Car Legs to level 10, but also purchased Lifting Crane Claw and Elevator Ascent, cultivating them to level 10 as well. Coupled with the expenses for food, transportation, and other necessities, Zhang Yu’s savings dwindled steadily. Fortunately, tutoring Song Hailong twice helped him maintain a balance of over 15,000.

At this moment, Zhang Yu obtained an Invisibility Talisman from Zhang Pianpian, and using the Crimson Marrow Primordial Qi to alter his appearance, he embarked on the journey for his trial lesson. Unlike the last time when he resorted to running, this time Zhang Yu utilized the Racing Car Legs technique. He felt the spiritual essence within his body resonating, emitting a buzzing sound like a car engine. Infused with spiritual power, his feet moved at lightning speed, leaving a trail of afterimages as he sped away.

“Compared to the Excavating Palm and Lifting Crane Claw, Racing Car Legs and Elevator Ascent are far more practical.” Recalling that level 10 Excavating Palm could excavate twice the material and level 10 Lifting Crane Claw allowed both claws to lift heavy objects simultaneously… Zhang Yu couldn’t help but feel speechless.

“Like Excavating Palm, long windup, slow movements, unsuitable for combat, only suitable for labor – truly peasant techniques.” In comparison, Racing Car Legs and Elevator Ascent offered far better value. As techniques commonly used by couriers, Racing Car Legs channeled spiritual power into the legs, accelerating movement, running like the wind, eliminating the need for cars or electric bikes, enabling couriers to traverse the city rapidly and arrive on time. Elevator Ascent allowed the user to focus spiritual energy and contract their muscles, allowing the body to become like a spring and unleash tremendous jumping force, enabling couriers to bypass elevator-less buildings, reaching their target floor with ease.

“Speaking of which, this is my first time cultivating a lightness technique. These are indeed very helpful in everyday life.” Thinking of the level 10 effects of these two techniques, Zhang Yu couldn’t help but smile, marveling at their practicality. Level 10 Racing Car Legs could protect the soles of shoes with spiritual power, reducing wear and tear, lowering the frequency of shoe replacements. Level 10 Elevator Ascent could transform vertical jumping into horizontal leaping, helping countless couriers jump over traffic lights and congested traffic, delivering goods on time.

He felt the spiritual power rising from his dantian, flowing into his legs and abdomen. With a contraction of his muscles, he leaped into the air, spanning over twenty meters, clearing the traffic light ahead.

“With Racing Car Legs and Elevator Ascent, each tutoring session will only take me about thirty or forty minutes to reach my destination. As my spiritual power becomes more abundant and my physical strength increases, my movement speed and jumping distance will further improve, then it will be even faster…”

Hanging below Zhang Yu’s neck, the doll watched this scene, still feeling incredulous. The doll thought to itself: “No way… these four techniques, although simple, have all advanced to level 10 in such a short time? Is this kid truly the potential I unlocked? Then I want to unlock myself too. How did he do it?”

During these five days, besides cultivating these four new techniques, Zhang Yu spent most of his time diligently practicing Crimson Marrow Primordial Qi. Unfortunately, without the augmentation of Primordial Qi Pills and being distracted by other matters, his physical strength only improved to level 1.98 in these five days.

“I really want to eat Primordial Qi Pills, cultivating without them feels like a loss.”

Zhang Yu arrived at the small building within the industrial park again. The middle-aged man who had received him before had been waiting for a while, and he smiled as he looked at Zhang Yu, “You’ve arrived?”

“Speaking of which, I still don’t know how to address you, sir?” Zhang Yu casually asked.

The other party replied, “You can call me Black Crow. Please follow me, the teachers are already waiting for you.” Zhang Yu followed him to a hidden door, entering the underground tutoring base. Guards were stationed every five steps, sentries every ten. Tattoos like ‘Studying Every Day’, ‘Learning in Secret’, and ‘Tutoring for All’ were visible on the guards’ bodies, revealing them as members of the Dark Learning Gang. What Zhang Yu found strange, however, was that each gang member had a number ‘0’ displayed above their head, making Zhang Yu wonder what this number represented.

Suddenly, a guard with ‘122’ above his head jogged past. The number above his head kept changing, from 122 to 123, then 124. Zhang Yu could no longer suppress his curiosity and asked, “What do these numbers above your heads mean?”

Black Crow, upon hearing this, cheerfully replied, “This is a post monitoring system developed in cooperation with a righteous deity after the gang adopted corporate management. Being away from your post for a certain period of time will result in a deduction of salary. He’s been deducted so much… maybe he has diarrhea?”

Zhang Yu’s lips twitched, “Isn’t that too strict?”

Black Crow smiled faintly, “These days, anyone with a bit of ambition is in debt. Getting a little salary deducted at work is just a necessary trial for young people.”

Zhang Yu laughed awkwardly, “Haha, running a gang is really like going to work.”

Black Crow’s eyes lit up, and he said, “Thank you for your praise. The gang leader has been committed to normalizing and corporatizing the Dark Learning Gang. Hopefully, it will become a new company and enter the city in the future.” Saying that, he sighed, “After all, if it weren’t for not being able to find a good job, who would willingly join a gang? Once you’ve joined a gang, your resume is completely ruined, and you’ll never have a chance to enter a big company.”

Good grief… Zhang Yu understood it now. It turned out that gangs were made up of people who couldn’t find jobs? This place was simply an unemployed persons mutual aid association.

Black Crow pointed ahead and said, “The tutoring classroom is up ahead. The toilets are on the left and right. Continuing down the stairs, there are training rooms, bathhouses, and a cafeteria…”

Just as Black Crow was introducing the facilities, a commotion erupted from the classroom door not far away. Zhang Yu turned his head to look. The first thing that caught his eye was a poster that read: Enroll in the White Dragon Tutoring Class and enjoy the teaching life of the Number One High School all night long. During the day, you may just be an ordinary student at an ordinary high school, but at night, you can be a White Dragon person and enjoy the joy of soaring grades.

Below the poster, a student complained, “The teacher is so gentle that even poor students don’t have to kneel. What kind of White Dragon Class is this? I paid to experience the teaching quality of a prestigious school. What’s the difference between this and studying in an ordinary high school during the day…”

Zhang Yu was shocked, people actually paid to experience the teaching life of White Dragon High School? But the next moment he laughed at his own shock.

“Isn’t that obvious? With my understanding of these deranged students and deranged parents in Songyang City… If paying could allow them to experience the teaching life of White Dragon High School, even if it was just advertising, there would definitely be people lining up to pay.”

At the same time, in another classroom, several teachers were chatting while puffing on cigarettes. An old man with white hair and the words ‘One Lesson a Day’ tattooed on his arm took a deep breath and exhaled the fumes of a Dao Heart Buffer. As an important medicine for enhancing Dao Heart, Dao Heart Buffers were widely circulated in Kunxu due to their extreme addictiveness, and were even made into different types such as cigarettes, wine, and drinks for people to use.

The old man took a few more puffs before saying, “How is this new teacher? I heard he might be from a key high school.”

Across from the old man, a middle-aged woman with a scar on her face said coldly, “What kind of academic aces do key high schools take in? Those students are rich and smart to begin with. How can a teacher who’s used to teaching those students teach underachievers? Has he ever come into contact with useless students below 450 points?”

“With the grades of most of the students here, if they were thrown into a key high school… they would be considered school traitors. Can he teach them?”

Another middle-aged man over 3 meters tall was practicing martial arts in a rigid manner. His exaggerated muscles were covered in needle marks, indicating that he was a physical cultivation expert. The 3-meter-tall middle-aged man hummed, “A teacher from a key high school wants to teach Excavating Palm, Racing Car Legs?”

“Has he ever worked on a construction site? Has he ever delivered food? Does he have the ability to teach them?”

“I’ve been laying bricks on construction sites for 11 years, and Che Nu has 8 years of delivery experience. Can he be more familiar with these two martial skills than us?”

The old man didn’t have such strong opinions and laughed, “After all, he’s an expert who can cultivate Limitless Cloud Hand to level 10. Let’s watch him first.”

A moment later, Black Crow led Zhang Yu in and introduced him to everyone, “This is Ma Yunteng, Teacher Ma, who is trying out the class today.”

Black Crow pointed to the old man and said, “This is Cai Tou, who has taught Limitless Cloud Hand.”
