Starting with the consumables of the Demonic Sect, one can barely achieve immortality.

Yan Cheng didn't hesitate for a moment and made a decisive decision:

"start!"

As the bright pearl on the silver mirror in his mind shone brightly, the text of the "Yin Corpse Evil-Traveling Technique" in the mirror began to be added to and deleted on its own, eventually evolving into a long incantation that was seven or eight times longer than the original text.

During this process, Yan Cheng also learned about some of the background stories hidden behind the magic techniques.

In the ancient times when immortality was prevalent, the art of corpse refining was considered the lowest of the low, and even the demonic sects that cultivated the path of the underworld disdained to study it.

Not to mention the beastly method of forcibly reviving someone who has already died once and then forcing them to transform themselves into a corpse puppet.

Back in the day, he would have been struck down by heavenly lightning and reduced to ashes.

Until the celestial dynasty that restrained cultivators from acting recklessly collapsed.

The ancestors of the Taiyin Immortal Sect found fragments of the "Shangyin Heaven Corpse Dao Chapter" in the ruins of the Immortal Dynasty, which evolved into the cultivation method used by the living corpses today.

In ancient times, the immortal path flourished. The original intention of this method was to allow cultivators whose physical bodies died unexpectedly but whose souls were still intact to continue their cultivation by using the cold and yin energy between heaven and earth, so that they could eventually turn death into life and continue their path.

Unable to hold on any longer, they fell into the hands of the kind-hearted immortal cultivators of the Immortal Sect. Now, it has evolved into a supreme and wondrous method of first leaving people half-dead and then forcing the living corpses to cultivate.

The living corpses practice the "Yin Corpse Walking and Evil Technique," which involves drawing the Yin energy from the coffin into their bodies and then opening up their Dantian (lower abdomen) and Qi Palace.

Although the principle is no different from the cultivation of ordinary living people during the Qi Refining stage, what is absorbed during cultivation is Yin Qi, and what is refined is also Corpse Fiend.

No matter how much you cultivate, you'll still be a dead person!

The revised version of "Shang Yin Tian Shi Dao Zhang" is different.

It was originally intended as a transitional method. Even if a cultivator was initially forced to cultivate with yin energy, as long as they switched to cultivating other spiritual energy midway and cleansed their body of yin energy, they could hope to escape the body of the dead and be reborn!

The ancient immortal dynasties had strict laws and regulations, which strictly prohibited cultivators from possessing other people's bodies.

If cultivators can use this method to rebuild their dead bodies into living bodies, they will naturally not need to take a desperate gamble and seize another body to find a new one.

The original intention was good, but when it got into the hands of the Immortal Sect...

Yan Cheng couldn't help but curse under his breath again. A wave of drowsiness washed over him, and he couldn't help but lie back down in the coffin.

This body has died once, and it is only by the warmth of the yin energy in the coffin that it can remain conscious for a short period of time each day.

Now, it's time to rest in peace.

Yan Cheng believed that the other zombies were in the same situation.

For this reason, he was even more convinced that even if all the living corpses devoted themselves to cultivation, very few would be able to achieve any real mastery.

The zombies are already conscious for very short periods, and once fatigue sets in, even the strongest will can hardly resist their instincts.

However, it's not necessarily a good thing to have mastered a skill.

Yan Cheng stared at the countless soul lamps hanging on the ceiling, feeling as if he were being stared at by hundreds of eyes at the same time, and his hands gripping the coffin lid tightened involuntarily.

The next moment, he slammed the coffin lid shut.

……

"The first step in cultivating the Tao is to gather vital energy, which is then concentrated in the upper, middle, and lower dantian. This combines the energy of the liver and lungs, and gathers the yin fire and gui water in the dantian, thus forming the evil spirit."

Hearing the chanting, Yan Cheng groggily opened her eyes and looked up to see the girl in black robes and several figures sitting around her listening to the sermon.

On the first and fifteenth of each lunar month, the girl in black robes would come to the Hall of Longevity to instruct the corpses in the "Yin Corpse Walking and Killing Technique".

As she had said before, the physical bodies of the corpses in the hall were not even qualified to be refined into corpse puppets.

As a disciple of the Immortal Sect, she had no choice but to expend extra effort to personally guide the corpses through the hurdle of guiding Qi into the Dao.

The living corpses sitting below her at this moment were all outstanding talents who had successfully drawn qi into their bodies and entered the early stage of qi cultivation over the past few months.

The girl in black robes did not immediately extract their souls, but instead granted them the status of disciples of the Corpse Immortal Sect as promised, so that they would serve her day and night and listen to her teachings.

Yan Cheng could see it clearly; this guy just wanted a higher quality corpse puppet.

If one day she determines that a certain living corpse has exhausted its potential and there is no way to advance further, she will definitely shake the golden bell without hesitation and refine it in an instant.

It sounds nice to call them "disciples in name only," but frankly, they're just people with greater potential.

For this reason, even though Yan Chengzong had completed the first stage of the "Upper Yin Heaven Corpse Dao Chapter" and become a cultivator in the early stage of Qi Refining, he had never revealed his cultivation level.

He practiced this ancient technique, and like the other corpses, he relied on the yin energy in the coffin to cultivate.

What she cultivated was clear and pure Yin Star Qi, not the Yin Corpse Sha that the black-robed girl wanted the corpses to cultivate.

For the cultivator himself, the former's quality and potential are far superior to the latter's, the difference is like heaven and earth.

But what the Immortal Sect needs are people who can make excellent corpse puppets.

As for the future of talented individuals? What future do corpse puppets have?

Yan Cheng's cultivation was not based on corpse demons. In the eyes of the black-robed girl, he was probably even worse than someone with no cultivation at all, and would be disposed of as a defective product at any time.

The important thing is to seize every moment to improve one's cultivation and prepare for future escape.

The living corpses before them, who had cultivated into Corpse Fiends and been granted the status of nominal disciples, seemed completely unaware of this, focusing intently on listening to the black-robed girl's sermon.

Yan Cheng had mastered the "Shangyin Tianshi Dao Zhang" (Chapter on the Corpse Path of the Upper Yin Heaven), and his understanding of Yin-attribute cultivation techniques surpassed that of any of the living corpses present.

What the woman said was clearly all about the Yin Sha Body Refining Method, all in order to help the corpses cultivate strong and resilient bodies.

However, it has nothing to do with the soul and is of no help to the Great Dao.

The newly initiated Qi cultivators listened intently.

The fact that these undead were able to cultivate corpse demons so quickly shows that they have some talent in cultivation.

Having no chance to attain immortality in life and living an ordinary, uneventful life, no one expected that they would be reborn after death with a path to cultivation. No one wanted to miss this heaven-sent opportunity.

Even though the girl in black robes never concealed her purpose in teaching the corpses, a sliver of hope always lingered in their hearts:

If I am truly a one-in-a-million talent who has achieved great results, can I escape the fate of being treated as waste material?

These dead people did not have a deep understanding of the cultivation method they were practicing, and they did not know that ever since the girl in black robes made them practice the "Yin Corpse Walking and Killing Technique", they had never had the chance to truly master it.

Only Yan Cheng knew, but that was all he knew.

Just then, a beautiful but pale-faced female corpse who had been practicing Qi cultivation suddenly clutched her stomach and screamed in agony.

Strands of scorching white smoke billowed from her seven orifices, as if to burn her face into mangled flesh!

The corpses' expressions changed, but the girl in black robes remained calm.

"This is a sign of the yang fire turning against itself."

"The human body contains both yin and yang energies. Although you have died once, there is still yang energy remaining in your bodies."

"However, our school's techniques are of the Yin nature. Once the Yang energy in the human body clashes with the Yin energy, there is a risk of Yang fire backfiring and burning the five internal organs."

He smiled slightly as he spoke:

"Gentlemen, there is no need to worry. With thousands of years of history, the Immortal Sect naturally has methods to deal with the backlash of Yang Fire."

"And by finding any living corpse and eating its heart and liver to replenish the yin energy, the yang fire can be extinguished and the two energies can be harmonized."

"Gentlemen, there's no need for you to feel embarrassed about this."

"You are now cultivators, while they are still mortals at this moment."

"Being able to offer their hearts and souls for your use is one way to contribute to my immortal sect, and I believe they are certainly happy about it."

"Well then, let's randomly select a lucky winner..."

She gently shook the handbell:

"No. C, number fifty-seven, coming out of the coffin."

As Yan Cheng was lamenting the shamelessness and callousness of the girl in black robes, he suddenly felt his legs straighten, and he involuntarily stood up from the coffin.

The girl in black robes glanced at him and clicked her tongue repeatedly.

"What a waste of such a beautiful face."

The next moment, with just a wave of his hand, the Qi-cultivating female corpse engulfed in Yang Fire roared and pounced on Yan Cheng!
