Chapter 215: Zhang Yu's Rapid Progress and the Golden Teacher Trial Class
Staring at the poster, Zhang Yu hesitated, half-believing, half-doubtful. “Is this really the hottest market?”
On the other side, Hei Ya had already sent another message:
Hei Ya: Silver Hair Economy — Elderly tutoring classes. Right now, it’s the most profitable segment in the Dark Tutoring Realm.
Hei Ya: You haven’t touched this market before, since your previous techniques were more suited to students and construction workers. That’s why you’re unfamiliar with it.
Hei Ya: I don’t know your current situation, but since you asked, I’ll tell you — this is the most lucrative market right now. It’s also where our Anxue Alliance is locked in fierce competition with the Jinkē Alliance.
Hei Ya: The theoretical lifespan limit for Qi Cultivation Stage practitioners is 150 years. So in Songyang City’s tutoring market, there’s a massive population of elderly learners.
Hei Ya: They have savings, and to stay relevant in the job market, they must constantly refine their cultivation, keep up with new technique updates, and adapt to the latest versions — otherwise, they’ll be left behind.
Hei Ya: So the demand for elderly tutoring has always outpaced supply. It’s extremely profitable.
Hei Ya: But the market is also demanding. Only those who’ve reached Peak Qi Refinement and still work into old age can afford to keep learning. They’re not interested in basic techniques — they need high-level, advanced methods.
Hei Ya: Besides the new version techniques required for work, there are also longevity techniques, detoxification methods for long-term medicinal side effects, and recovery techniques for chronic internal injuries — all in high demand.
Hei Ya: After all, only by maintaining peak physical health can they survive the damage from years of pill consumption and overtime — and keep their edge in the workplace.
As Zhang Yu read through Hei Ya’s messages, he began to grasp just what kind of market was currently dominating the Dark Tutoring Realm.
He thought to himself, “Makes sense. With each passing year, the number of college, vocational, and high school graduates keeps rising — naturally, the number of senior cultivators is growing too. These elders have more savings than young people, and they need far more expensive techniques. This really is a massive market.”
Zhang Yu then asked, “What about Chunqiu Wujin Chan? Is there a market for that?”
Hei Ya: Chunqiu Wujin Chan from Xianyun Group? Ha! Of course there is. Master Ma — are you actually proficient in that top-tier technique?
Anxue Alliance was backed by Shenhai Education Group — long-time rivals of Xianyun Group. They had a history of reverse-engineering and pirating Xianyun’s techniques.
And Chunqiu Wujin Chan — a master-level Body-Refining Technique known for enhancing metabolism and eliminating drug toxins — was exactly the kind of high-value technique that made Hei Ya’s eyes light up like a cat spotting blood.
Hei Ya: Three days from now, we’re scheduling trial classes for several potential gold-tier instructors. If you’re interested, I can arrange for you to participate.
Zhang Yu made arrangements with Hei Ya for the trial class three days later. Meanwhile, Bai Zhenzhen frowned and said, “I don’t think I have any techniques suitable for teaching elderly students.”
Fujie chimed in, “A Zhen, you’ve got Zhen Linggen in your body, and your dantian is infused with Thunderous Martial Energy. Your true path to strength lies in combat.”
“Right now, the Alliance War between Anxue and Jinkē is perfect for you. It’ll earn you money, sharpen your battlefield instincts, and prepare you for the Foundation Establishment Exam in three months.”
“In my opinion, Zhang Yu should take the gold teacher role and teach, while you join the Alliance War — build strength, earn cash, and stay sharp. That’s the best path for both of you.”
Zhang Yu frowned. “Alliance War… won’t there be danger?”
Fujie replied, “Of course there is danger in real combat! But compared to military-grade battles, corporate wars, or the future showdowns with the Evil God Cultists of the Zhou Family — Alliance War is low-intensity.”
“If you can’t even handle a little risk, how do you expect to climb higher?”
Bai Zhenzhen nodded, her eyes flashing with resolve. “Fujie’s right. This is truly the path for me.”
“Yu, don’t worry. With Zhen Linggen supporting me and my speed, if I run into someone I can’t beat, I can just flee.”
Zhang Yu looked at her deeply. He knew this was her choice — her decision, made to prepare for the Foundation Establishment Certificate. As her closest friend, he could only respect it.
So Bai Zhenzhen logged out of Kunshen World, added Hei Ya as a friend, and joined the Anxue Alliance’s Alliance War under her alias — Le Mulan.
Hei Ya: Teacher Le, you’re just in time. We’re short on top-tier talent. There’s a mission in four days — would you like to join?
After finalizing the arrangements, Zhang Yu and Bai Zhenzhen focused entirely on their respective preparations — one for teaching, the other for battle.
…
Three days passed in the blink of an eye.
During that time, thanks to the High School Saint Body enhancement, Zhang Yu advanced his Grief Fermenting Technique to Level 10, transforming his body into a living suit of copper-plate armor.
At Level 10, when he tensed his muscles, his skin shimmered with a deep, ancient copper glow — as if clad in a seamless layer of battle armor.
He tested it with a small knife, slicing his forearm. It took over 30% of his strength to draw a faint line — and even then, the cut barely broke the surface. It felt like cutting through thick, hardened keratin.
Clearly, after cultivating this technique, his skin had developed extraordinary resilience and protection.
But even after reaching Level 10, Zhang Yu still felt a lingering sense of incompleteness.
Fujie observed, “This Grief Fermenting Technique likely has a continuation. But you only purchased the Qi Cultivation-stage version.”
“To continue past Level 10 and push it to Level 20 after Foundation Establishment, you’ll need to buy the Advanced-stage license.”
Zhang Yu wasn’t particularly interested. Fujie didn’t know that he was cultivating multiple techniques not for immediate use, but to form the Martial Dao Holy Embryo — and he hadn’t yet decided which technique he’d pursue after Foundation Establishment.
Over the past three days, while refining his skin with Grief Fermenting Technique, Zhang Yu also borrowed Bai Zhenzhen’s Xuanlei Lightning Acupuncture Set to train in the Thunderous Marrow Cleansing Scripture — an Expert-Level Cultivation Technique he’d obtained from Songyang High School.
This technique used electric shocks to stimulate bone marrow regeneration, accelerating skeletal restructuring — one of the top-tier Body-Refining Techniques for increasing bone density.
And the Xuanlei Lightning Acupuncture Set from Songyang High School? It was specifically designed to complement this very technique.
Zhang Yu was now pierced through with 999 silver needles, each channeling crackling lightning deep into his marrow, as he refined his bones using the Thunderous Marrow Cleansing Scripture.
As he pushed the technique from Level 1 to Level 9, every bone in his body — except the skull — had completely regenerated. Beneath his skin, they now glowed with a silvery frost-like sheen.
Then, at Level 10, his skull underwent a sudden transformation — as if forged in a thousand hammer blows — instantly turning the same silver-white.
With his entire skeleton now reborn, bone density and strength skyrocketed. His weight increased dramatically — now over 300 kilograms — despite minimal changes in body size.
The Level 10 effect also allowed Zhang Yu to gradually heal bone damage simply by circulating the technique.
He tapped his chest and felt it — the flesh, hardened by Grief Fermenting Technique, and the ribs, reinforced by Thunderous Marrow Cleansing Scripture, wrapped his internal organs like dual armor.
At last, his Physical Strength Level broke through the final barrier — reaching Peak Qi Refinement Level 10.
“Physical Strength only increased by about 0.06 levels,” he mused, “but these two Body-Protection Techniques have vastly amplified my overall strength.”
“Indeed, once Dao Heart, Martial Energy, and Physical Strength all hit their peak in the Qi Cultivation Stage, mastering more techniques becomes the best way to grow stronger.”
He glanced at A Zhen, still deep in cultivation, and said to the Xuanlei Lightning Acupuncture Set, “Spirit, end training mode.”
A voice echoed from the needle box: “Training mode ended. Entering standby. Awaiting user command.”
With a flash of crackling light, the 999 needles shot back into the box, retracting from his body.
Zhang Yu cracked his neck, listening to the satisfying pops of his newly forged bones.
A small smile formed. “A Zhen, keep training. I’m off to the trial class.”
Bai Zhenzhen waved. “Good luck. Make some real money.”
…
The meeting point with Hei Ya was an abandoned underground transit platform.
Zhang Yu altered his appearance and arrived moments ago when he spotted a young girl standing before Hei Ya, arguing passionately.
Zhang Yu didn’t care for gossip — he turned to walk away.
But the girl burst out, “Teacher! My grandpa keeps watching porn during class! He’s watching porn during class! When I check his phone, it’s full of porn — not even space left for textbooks!”
She continued, “Because he’s not focused, his technique progress has stalled for months. His work performance has dropped.”
“My grandpa was never disciplined. My dad says he never wanted to work overtime — never got promoted before age 50. He couldn’t even afford my tutoring fees or my dad’s.”
“So please, I beg you — help keep an eye on him. Make sure he keeps up. He needs to earn more.”
“We won’t waste the money. We’ll save it — and come back to your school for future lessons.”
Hei Ya sighed, “Our teachers are too busy. We don’t handle classroom discipline.”
After a long, fruitless argument, the class finally ended, and the girl had to go pick up her grandfather.
Only then did Hei Ya exhale, turning to Zhang Yu with a smile. “Master Ma, you’re here.”
Zhang Yu raised an eyebrow. “That girl…?”
Hei Ya shrugged. “Oh, just a long-term pill-taker. His cognitive function declined with age. His family has low education and low income — they just want him to keep earning, so they sent him here.”
He added, “Just a heads-up — today’s trial class is real. You’ll be teaching real elderly students.”
“So, what lesson are you planning to deliver?”
Zhang Yu replied calmly, “Chunqiu Wujin Chan.”
