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

Looking at the poster, Zhang Yu said with some skepticism, "This is the hottest market?"

On the other side, Black Crow had already continued to send messages: The silver-haired economy, after-school classes for the elderly, is currently the most profitable market in the dark tutoring world.

Black Crow: Because the cultivation methods you showed before were more suitable for students and construction sites, and not very suitable for this market, you may not have had much contact with it.

Black Crow: I don't know your current situation. Since you asked, I'll talk about this most profitable market, which is also the market where our Dark Learning Gang is fiercely competing with the Golden Class Gang.

Black Crow: The theoretical lifespan limit of the Qi Refining stage is 150 years old, so there are a large number of elderly people in the tutoring market of Songyang City.

Black Crow: The elderly have some savings, and in order not to be eliminated by the market, they need to constantly cultivate, constantly learn new versions and updated cultivation methods in order to keep up with the times and maintain their jobs.

Black Crow: So the elderly tutoring market has always been in short supply and is very profitable.

Black Crow: It's just that the requirements of the elderly tutoring market are also very high. After all, those who can live to old age and continue to work are all Qi Refining peak experts for many years. What they need to learn is definitely not basic cultivation methods, but many high-difficulty cultivation methods.

Black Crow: In addition to the new version of cultivation methods required for work, there are also longevity cultivation methods, cultivation methods for metabolizing drug toxins after taking medicine for many years, cultivation methods for repairing hidden injuries in the body... These are all very popular.

Black Crow: After all, only by ensuring good health and overcoming the damage caused by years of taking drugs and working overtime can they continue to maintain their competitiveness in the workplace.

Looking at the messages sent by Black Crow, Zhang Yu basically had a certain understanding of what is most profitable in the current dark tutoring world.

He thought to himself, "That's right, as the number of college students, junior college students, and high school graduates increases year by year, the number of Qi Refining elderly people must also be increasing. This group of elderly people has more savings than young people, and the cultivation methods they need to learn are more expensive than those of young people. This is indeed a huge market."

Zhang Yu immediately asked again: "Is there a market for the Spring and Autumn Endless Zen?"

Black Crow: "The Spring and Autumn Endless Zen of the Immortal Rhyme Group? Haha, of course there is a market. Master Ma, do you know this top-level cultivation method?"

The Dark Learning Gang is backed by the Deep Sea Education Group. As an opponent of the Immortal Rhyme Group, it has always been most fond of cracking and pirating the cultivation methods of the Immortal Rhyme Group.

And the Spring and Autumn Endless Zen, as a top-level expert-level body refining cultivation method, also has the effect of enhancing metabolism and eliminating drug toxins. As soon as Black Crow heard Zhang Yu, under the pseudonym Ma Yunteng, mention the Spring and Autumn Endless Zen, he was like a cat smelling fish, and his interest greatly increased.

Black Crow: "In three days, the gang will arrange for several candidate gold medal teachers to have trial classes. If Master Ma is interested, I can arrange it for you."

Zhang Yu made an appointment with Black Crow for a trial class in three days. Bai Zhenzhen on the side frowned and said, "I don't seem to have any cultivation methods suitable for teaching the elderly."

Fu Ji said: "Ah Zhen, you have the True Spirit Root, and you also have the Thunder magic power injected into your dantian Qi Sea. The path to becoming stronger that is most suitable for you is ultimately combat."

"And the gang war between the Dark Learning Gang and the Golden Class Gang is very suitable for you right now. It can not only make you money, but also hone your actual combat ability and prepare you for the Foundation Establishment exam in three months."

"In my opinion, Zhang Yu will go to be a gold medal teacher and teach classes, and you will participate in gang battles to hone your strength while making money. This is the most suitable arrangement for the two of you."

Zhang Yu frowned and said, "Gang war... won't it be dangerous?"

Fu Ji said: "Nonsense, how can actual combat not be dangerous? But compared to the combat of real military-grade forces, compared to company wars, compared to the future battles between you and the evil god believers behind the Zhou family, the intensity of gang battles is definitely very low."

"If you don't even dare to take this little bit of actual combat risk, what are you thinking about climbing up?"

Bai Zhenzhen nodded, a look of determination flashing in her eyes: "Fu Ji is right."

"I am indeed suitable to take this path."

"Yu Zi, you don't have to worry. With the True Spirit Root to assist me, and my speed is so fast, even if I encounter someone I can't beat, can't I still run away?"

Zhang Yu took a deep look at Bai Zhenzhen, knowing that this was the path she had chosen, it was her decision, and it was the determination she had made in order to pass the Foundation Establishment Certificate. As a close friend, he could only respect this decision.

So Bai Zhenzhen also went down to the Kun God World, added Black Crow as a friend, and participated in the gang battles of the Dark Learning Gang with her original pseudonym Le Mulan.

Black Crow: "Teacher Le, it's great that you're here. The gang is currently short of experts like you. There will be an operation in four days. I don't know if you will participate?"

After completing the agreement with Black Crow, Zhang Yu and Bai Zhenzhen devoted themselves wholeheartedly to their respective cultivation, preparing for the upcoming lectures and battles.

...

In the blink of an eye, three days had passed.

In these three days, with the blessing of the High School Holy Body, Zhang Yu first cultivated the Grievance Evil Skill to level 10, and cultivated a body of bronze armor corpse skin.

And after this cultivation method reached level 10, he only saw that his whole body was running with energy, and a burst of bronze color appeared under his skin, as if he was wearing a layer of armor.

He tried to cut the skin on the back of his hand with a knife, and it took more than 30% of his strength to produce a trace of blood.

It was clearly cut on his own skin, but it was like cutting on a thick and hard stratum corneum.

Obviously, after cultivating this Grievance Evil Skill, Zhang Yu's skin had far more toughness and protection than before.

And after cultivating this Grievance Evil Skill to level 10, he also felt a sense of unfulfilled meaning.

Fu Ji pointed out from the side: "This Grievance Evil Skill should have a follow-up version."

"But what you bought is only the right to use the Qi Refining version."

"If you want to continue cultivating this cultivation method after Foundation Establishment, and push this cultivation method to level 20, then you have to buy the right to use the Foundation Establishment version."

Zhang Yu was not very interested in this, after all, Fu Ji didn't know that he was cultivating so many cultivation methods to form a Martial Dao Holy Embryo. He hadn't thought so much about what cultivation methods to cultivate in the future Foundation Establishment stage.

And in these three days, in addition to refining his skin with the Grievance Evil Skill, Zhang Yu also borrowed Bai Zhenzhen's Xuan Lei Electric Moxibustion Needle Set to help him cultivate the expert-level cultivation method Thunder Marrow Washing Scripture obtained from Songyang High School.

This Thunder Marrow Washing Scripture is a top-level body refining cultivation method that enhances bone density by assisting bone marrow generation through electric shock and accelerating bone remodeling.

And Songyang High School's Xuan Lei Electric Moxibustion Needle Set can be said to have been brought over by Songyang High School in order to cooperate with this cultivation method.

He saw that Zhang Yu's whole body was covered with 999 silver needles, and thunderbolts ran through his bone marrow, reshaping his bones with the Thunder Marrow Washing Scripture.

In the process of Zhang Yu pushing the Thunder Marrow Washing Scripture from level 1 to level 9, all the bones in his body except the skull had been completely renewed, emitting a silver frost-like luster under his skin and flesh.

And at this moment, when Zhang Yu finally pushed the Thunder Marrow Washing Scripture to level 10, his skull seemed to have been tempered by thousands of hammers in an instant, and instantly became a piece of silver frost.

And as the bones all over his body were renewed, the bone density and bone strength soared, Zhang Yu's weight also increased with the increase in bone weight, and suddenly reached more than 300 kilograms under the condition that his body shape did not change much.

The level 10 effect of the Thunder Marrow Washing Scripture also allowed him to slowly repair the damage to his bones by running this cultivation method.

Patting his chest, Zhang Yu felt that the skin and flesh tempered by the Grievance Evil Skill, coupled with the ribs tempered by the Thunder Marrow Washing Scripture, wrapped his internal organs like double armor.

And Zhang Yu's physical strength finally crossed the last step at this moment, and finally reached the limit of Qi Refining, the level 10 physical strength.

"Although the physical strength has only increased by about 0.06 levels."

"But these two body protection cultivation methods make my strength far surpass before."

"Sure enough, after the Dao Heart, mana, and physical strength of the Qi Refining stage reach the limit one by one, cultivating more cultivation methods is the best way to improve strength."

Looking at Ah Zhen who was still cultivating on the side, Zhang Yu said to the Xuan Lei Electric Moxibustion Needle Set: "Spirit, stop the cultivation mode."

The voice of the spirit came from the needle box: "Stop the cultivation mode, start standby, waiting for user commands."

He saw 999 silver needles flashing with electric light, shooting out from Zhang Yu's body and returning to the needle box.

Twisting his neck, listening to the crackling sound coming from the brand new bones, Zhang Yu smiled slightly and said, "Ah Zhen, you continue to cultivate, I'm going to the trial class."

Bai Zhenzhen waved her hand and said, "Good luck, make more money."

...

The place Zhang Yu agreed with Black Crow was located in an abandoned underground transportation station.

Zhang Yu changed his appearance and had just arrived at the platform when he saw a girl standing in front of Black Crow, discussing some topic with Black Crow.

Zhang Yu had no intention of listening to other people's gossip. As soon as he turned his head, he planned to go to the side and wait.

But he heard the girl angrily say: "Teacher! My grandfather secretly watches porn as soon as he goes to class, and secretly watches porn as soon as he goes to class! As soon as I open his phone, it's all porn, and there's no place to store the textbooks!"

The girl's words made Zhang Yu stop immediately.

The girl continued: "Because he doesn't study hard in class and can't keep up with the progress of his cultivation method, his work performance has declined for several months!"

"My grandfather has been undisciplined since he was a child. I heard my dad say that my grandfather was unwilling to work overtime when he was working back then. He hadn't been promoted by the time he was 50 years old, and he couldn't afford my dad's and my tutoring fees."

"So I beg you, please help me keep an eye on him more so that he can keep up with his cultivation method and earn more money."

"We won't spend this money randomly. We'll save it all for you and come to your house for tutoring in the future."

Black Crow said helplessly: "Our teachers here are very busy and are generally not responsible for classroom discipline."

After arguing for a long time, the class in the classroom next door finally ended, and the girl had to pick up her grandfather from school.

Black Crow breathed a sigh of relief, looked at Zhang Yu standing on the side, and smiled, "Master Ma, you're here."

Zhang Yu asked curiously, "Just now that..."

Black Crow casually explained: "Oh, it's a student who has been taking medicine for a long time and whose IQ has decreased in old age. His family members have poor education and low income, and they all hope that this mentally retarded student can continue to make money, so they sent him here."

Black Crow continued: "Let me remind you that today's trial classes are all real classes, and the people you will face are all real elderly customers."

"I don't know which class you plan to teach?"

Zhang Yu said lightly: "Spring and Autumn Endless Zen."
