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

Zhang Yu looked at the newly purchased 'Grievance Fiend Art' on his phone, flipping through the contents of this cultivation method.

This top-tier expert-level cultivation method, due to the requirement of resentment energy for cultivation, had its price plummet, and Zhang Yu bought it for 500,000.

At this moment, after carefully reading it, Zhang Yu planned to practice body refinement according to the methods described within.

He touched the work badge hanging on his chest, which read 'Frontline Employee' in large characters, constantly absorbing the surging resentment energy in the air.

This work badge-like object was precisely the external spiritual root sent by Zhou Chechen—the Resentment Spirit Root.

The reason it was shaped like a work badge was said to make it easier to store resentment energy.

At this moment, as Zhang Yu channeled his magic power into the Resentment Spirit Root, the entire world underwent a drastic change in his perception.

The usually tranquil and peaceful Songyang High School now appeared to him as wisps of black energy soaring into the sky, with various distorted and struggling faces filling the black energy, emitting howls like ghosts and wolves.

"Is this resentment energy?"

Zhang Yu knew that so-called resentment energy was a residue of negative human emotions, commonly found in Kunxu's cemeteries, schools, and companies.

However, because there were enough living people in schools and companies, resentment energy was constantly generated, and the amount of resentment energy far exceeded that of cemeteries.

But the advantage of cemeteries was that the resentment energy was purer, older, and of higher quality than that of schools and companies, so the resentment energy of the dead had a wider range of uses and a higher selling price.

Zhang Yu thought, "According to Fuki, if there are enough old ancestors buried at home, and they have been buried long enough, just renting out the cemetery as a cultivation site every month can earn a lot of money."

"Alas, having an old person at home is like having a treasure. It's a pity that Zhang Yu's ancestors couldn't even afford a cemetery, and the money they saved was barely enough to pay for corpse disposal fees."

He controlled the Resentment Spirit Root, taking a deep breath, and felt wisps of resentment energy pouring into his mouth and nose.

In an instant, waves of intense anger, humiliation, regret, despair… constantly impacted Zhang Yu's brain, allowing him to experience the strong negative emotions erupted by many underachieving students when faced with poor rankings, declining grades, and insults.

Zhang Yu quickly circulated the 'Crippled Ox Sacrificing Heart Sutra' to resist the impact of these negative emotions, and began to refine these strands of resentment energy according to the method on the 'Grievance Fiend Art'.

According to the cultivation method of the 'Grievance Fiend Art', one must absorb the resentment energy, wash away the specific emotions within it, leaving behind a pure fiendish energy, and then imitate the method of refining corpses to refine one's own skin and flesh, eventually refining a body of copper armor corpse skin that is not afraid of swords and spears.

After spending several minutes, Zhang Yu stumbled through the first round of cultivation, and felt a subtle coolness coming from a palm-sized area of skin on his chest.

He thought to himself, "If I follow the steps, this cultivation method will probably take a year and a half to achieve something."

"Fortunately, with my efforts, the Feather Book can quickly complete this cultivation method."

Zhang Yu looked up and saw that the 'Grievance Fiend Art' displayed on the Feather Book had changed from Level 0 (0/1) to Level 1 (2/10).

The ultimate effect brought by the High School Sacred Body was that when Zhang Yu cultivated any Qi refining stage cultivation method, one round of cultivation was equivalent to three rounds.

This was precisely why he had the confidence to frantically cultivate cultivation methods in the next three months, gradually making up for the foundation of the Martial Dao Sacred Embryo.

A dozen minutes later, as round after round of 'Grievance Fiend Art' cultivation was completed, it was as if a thunderclap flashed through Zhang Yu's mind, and scenes of using resentment energy to temper the skin of his chest flashed before his eyes.

At the same time, he felt as if something alive was growing violently under the skin of his chest, tightly wrapping his chest like a film.

"Grievance Fiend Art Level 1 is complete."

Zhang Yu slowly recalled the cultivation memories in his mind, and felt the changes in his body, thinking to himself, "Each level of the 'Grievance Fiend Art' is to temper the skin and flesh of different parts of the body. Finally, at Level 10, one will cultivate a body of copper armor corpse skin, like a close-fitting inner armor, greatly increasing the body's defensive power."

After feeling it for a while, Zhang Yu continued to cultivate, planning to seize the time to push this 'Grievance Fiend Art' to Level 10.

Time passed quickly as Zhang Yu cultivated, and it was soon time to leave school and enter the evening.

Under the night sky, 999 silver needles flickered with electric light, piercing into different parts of Bai Zhenzhen's body from top to bottom.

As Bai Zhenzhen circulated the 'Thunderclap True Body', she could see electric light jumping back and forth on the silver needles, constantly stimulating the nerves and muscles throughout her body.

Bai Zhenzhen could feel that, in addition to the improvement in physical strength, the nerves that had not grown for a long time were now, under the effect of the Xuanlei Electro-Acupuncture Needle Set, like withered trees meeting spring, and began a new round of growth, helping her to grasp her body more deeply, more delicately, and more quickly.

If the original 'Thunderclap True Body' was just a second-rate expert-level body refining cultivation method, then after the deduction of the True Spirit Root, the blessing of Thunder Law Power, and the assistance of the Xuanlei Electro-Acupuncture Needle Set, it had the effect of a top-tier expert-level body refining cultivation method.

Suddenly, the electric light began to weaken.

The spirit of the needle box said, "Insufficient power, please charge in time."

Temporarily withdrawing the 999 silver needles, Bai Zhenzhen looked at Zhang Yu, who was beside her, and said, "Yu Zi, are you ready to go to the Dark Learning Gang?"

Zhang Yu, who was cultivating the 'Grievance Fiend Art' beside her, slowly opened his eyes, and a trace of fiendish energy flashed in his eyes.

After this whole day of cultivation, he had pushed the 'Grievance Fiend Art' to the level of 8 (15/90).

At this moment, Zhang Yu could feel that all the skin and flesh on his body, except for his face, was like an extra layer of film. Usually, this layer of film would not affect his movements, but as long as he exerted his strength, this layer of film would protect his body like a layer of iron armor.

Fuki, who was beside him, felt the changes in Zhang Yu's body, especially the faint and subtle lines on the exposed skin of his arms, and she exclaimed in her heart, "This guy's 'Grievance Fiend Art' is progressing so fast!"

"I feel like he has almost completed this cultivation method in just one day."

"Sure enough, after his potential was stimulated again last time, Zhang Yu's talent has become even more terrifying."

"Hehehe, good, good, good, this time, after passing the high school foundation building certificate and climbing to the second floor, the sky is the limit for birds to fly and the sea is wide for fish to leap."

Zhang Yu slowly stood up, twisted his somewhat dry and stiff skin, nodded and said, "Let's go."

However, before leaving, Bai Zhenzhen returned the Xuanlei Electro-Acupuncture Needle Set to charge.

Leaving the school gate, Zhang Yu and Bai Zhenzhen's figures flickered, each using their movement techniques, found a place to change their figures, disguised their faces, and then sped towards the Dark Learning Gang's base.

……

When Zhang Yu and Bai Zhenzhen arrived outside the park in the identities of Ma Yunteng and Yue Mulan, two tutoring teachers.

The two were surprised to find that in the brightly lit park, the security team of Xianyun Group was moving in and out, and the constables were assisting, escorting the members of the Dark Learning Gang out one by one.

One of the gang teachers, with a gray face and swollen face, cried out, "This is my first time here to give tutoring! It's really my first time."

The constable beside him snorted coldly and said, "Does your family know that you are doing illegal things here?"

The teacher said with a mournful face, "It has nothing to do with my family, they believe in me very much, they don't know that I would do such a thing."

"I was temporarily blinded by greed, I wanted to earn some quick money, I thought it would be okay to tutor once or twice."

"I really know I was wrong, I'm sorry to my parents, they gave birth to me, not to let me give illegal tutoring."

"Please let me go, I really have no money to compensate…"

Another old constable beside him reminded, "The names, identities, and motives of these people in the dark tutoring world are all fabricated. There is not a word of truth in their mouths. You can't believe a single word of what they say. You will know more about it in the future."

In the distance, Zhang Yu, hiding in the shadows, exclaimed, "The Dark Learning Gang has been eradicated?"

Bai Zhenzhen said helplessly, "What should we do now? Should we find another gang and start all over again?"

Fuki reminded, "Don't you have the contact information of that middleman from the Dark Learning Gang, that Black Crow?"

"Contact him and see."

"The Dark Learning Gang is not small. The destruction of one park does not mean that the gang is gone."

Zhang Yu also remembered that he had added a friend in the Kun God World and could contact the middleman named Black Crow.

So Zhang Yu opened the Kun God World on his phone, and soon contacted Black Crow.

After some communication, Zhang Yu learned that the dark tutoring world in Songyang City has been turbulent recently.

In particular, the infighting between the Dark Learning Gang and the Gold Class Gang has become more and more serious, with various incidents of stealing course outlines, burning teaching materials, assassinating gold medal teachers, and reporting tutoring spots.

And as far as Zhang Yu knew, the backers of these two gangs were the Deep Sea Education Group and the Xianyun Education Group, respectively.

Zhang Yu thought, "The Dark Learning Gang and the Gold Class Gang are fighting so fiercely, does it mean that the conflict between the two behemoths behind them, the Deep Sea Group and the Xianyun Group, has also escalated?"

For some reason, Zhang Yu always had a feeling that since this year, the companies in Songyang City have been showing a kind of anxiety, a feeling that the intensity of competition is constantly escalating.

Temporarily suppressing his speculation about the situation in Songyang, Zhang Yu still focused his attention on the situation of the Dark Learning Gang.

Zhang Yu said, "According to Black Crow, with the infighting between the two gangs, many gold medal teachers in the Dark Learning Gang have fallen. So they have been recruiting experts to give lectures or participate in gang battles."

Bai Zhenzhen asked, "If it's lecturing, what kind of courses are profitable now? Can the cultivation methods I know make a lot of money?"

"I feel like it's not fast enough to rely on tutoring high school students or construction workers."

Zhang Yu asked Black Crow, and the other party sent over a dynamic poster.

On the poster was a group of white-haired old people studying and cultivating diligently. One of the energetic old men said aloud, "At 90 years old, I have elders above and young children below. It is the age to venture and fight."

"I want to take my 130-year-old parents to eat pre-made dishes, I want to sign up my 60-year-old son for tutoring classes, I want to help my 30-year-old grandson rent a sewer room next to the subway, I want my 5-year-old great-granddaughter to be able to enter a key kindergarten. How can I stop studying? How can I be eliminated from the workplace?"

"In ancient times, there were 100-year-old prime ministers who recovered mountains and rivers, 500-year-old great demons who transformed into human form, and 1000-year-old old grandmothers who married immortals."

On the poster, the old man clenched his fists and shouted with fighting spirit, "Strive! It's never too late no matter how old you are!"
