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

"The True Method of Pulling Silk to Stabilize Yang" is a technique passed down in the Heavenly Corpse Path and is also the method used by the Longevity Palace in modern times to train silk weavers.

Yan Cheng already knew that the reason why the silk weavers were able to spit out puppet threads was because they used this technique to condense the yang fire in their bodies into silk threads.

He originally thought it was just a functional technique created to ensure the supply of silk threads.

I didn't expect that I had thought too highly of these demonic cultivators!

"The 'Pulling Silk Stabilizing Yang True Method'... is in fact a technique for cultivating the cauldron (body vessel)."

Yan Cheng's gaze was cold.

First, the silk weavers were fed with rejuvenating pills made from a large number of souls, so that they would develop a constitution that depended on yang energy.

As long as souls are continuously supplied, the capacity of yang energy that the silk weavers can bear will increase over time.

There is a method of releasing excess yang fire by spitting out silk, and this process is almost risk-free.

The only drawback is that the silk weavers' addiction to yang energy increases over time.

Eventually, the situation deteriorated to the point where the emperor was powerless to continue feeding the emperor with massive amounts of souls.

But what does that have to do with the palace? A worn-out silk weaver can simply be discarded.

Anyway, getting rid of these unfortunate souls in droves won't take much effort; all we need to do is cut off their soul supply...

"But now it seems that the puppet-pulling silk was merely a byproduct of the process of creating the silk weaver."

What the higher-ups truly cared about was the physical changes the silk weavers underwent throughout the entire process.

"Thus, they become perfect vessels for corpse cultivators to cultivate, containing yang energy within their yin bodies."

The cultivation methods left behind by the Heavenly Corpse Path clearly explain how to use the silk weavers after they have been transformed into cauldrons.

To some extent, it even makes up for the shortcomings of the "Yin Yang Su Cui Miao He Xuan Jing" that Yan Cheng had.

While this profound scripture is indeed the world's first-rate method of dual cultivation, its content focuses entirely on the practitioner himself and does not address how to improve the quality of the dual cultivation partner.

No matter how efficient the dual cultivation method itself is, if the cultivation partner has ordinary cultivation level and mediocre physique, the effect of dual cultivation will not be very high.

For corpse cultivators who practice Yin magic, the best partners for dual cultivation are undoubtedly the silk weavers who have cultivated Yang energy within their bodies through their techniques.

In the terminology of the Heavenly Corpse Path, they should be called Corpse-Raising Women.

"The corpse cultivator cultivates yin methods with a yin body, which is four yin and one yang; the yin body cultivates yang methods, which is three yin and two yang."

The latter is closer to a state of yin and yang balance, which is more conducive to the pursuit of the Dao, but it cannot be obtained through conventional cultivation methods.

The solution offered by the Heavenly Corpse Path is to treat the corpse-raising women as mere consumables, thereby creating corpse cultivators whose physiques are closer to the optimal state of yin-yang balance.

Yan Cheng put down the letter, deeply moved.

Amazing.

Putting aside the ethics and morality that Northern cultivators don't really care about, the solution provided by the Heavenly Corpse Path is perfect, and even secretly conforms to the cultivation principles put forward in the "Upper Yin Heavenly Corpse Path Chapter".

This was also the first cultivation method he had ever seen that did not trigger the Hidden Immortal Mirror to fill in the gaps.

The legacy left by the Heavenly Corpse Path to its successors is complete and represents the pinnacle that the art of corpse raising can achieve.

The only minor cost is that this method fundamentally cuts off the path to enlightenment for the corpse-raising women.

It does not have a Foundation Building chapter, nor was it ever intended for the Corpse-Raising Women to achieve Foundation Building.

Once a corpse cultivator successfully establishes their foundation with a perfect physique that balances Yin and Yang, their physical body will no longer be subject to the distinction between life, death, Yin, and Yang, and the mission of the corpse-raising women will be complete.

The remaining value is that it can become the furnace for the next batch of corpse cultivators.

Yan Cheng's Yin-Yang cultivation method inherently involves cultivating to achieve a balance of Yin and Yang, so he does not need to adjust his physique through dual cultivation with the corpse-raising woman.

But if he had that need, Yan Cheng believed she would do it without hesitation.

Even if I don't engage in dual cultivation with them, the corpse-raising women who have cultivated the "Pulling Silk Stabilizing Yang True Method" can't recover their cultivation. Why not let them demonstrate their value as much as possible?

Unbeknownst to him, Yan Cheng had already become a cultivator with the proper mindset of a celestial sect.

He glanced at Wang Qing and asked, seemingly casually:

How much do you know about the Corpse-Raising Woman?

Wang Qing's reaction was much stronger than he had expected; upon hearing this, she immediately stared at him warily.

Why are you asking that? What do you want?

Yan Cheng sighed softly:

"I was just asking."

"Fellow Daoist, you clearly know as much as I do. Do you think I could possibly trick you into switching your cultivation to this 'Thread-Pulling Yang-Stabilizing True Method'?"

Wang Qing blinked slightly, clearly having heard of the name of this cultivation technique, and stared at the scroll in his hand, asking:

"Is this scroll in your hand the 'True Method of Stabilizing Yang with Threads'?"

"I thought the cultivation techniques of the Corpse-Raising Woman lineage had long been collected by the Demonic Sect and stored in the Hall of Longevity."

"The Netherworld Sect is valued by the upper echelons of the Demonic Sect far more than people expect. In the past few hundred years, there have been no other sects in the Northern Territory that cultivate the Netherworld Sect."

Yan Cheng smiled slightly and tossed the letter to her:

"Some birds can't be caged."

"Moreover, the Heavenly Corpse Path is a powerful force that has withstood the pursuit of the Zhou Dynasty and the Immortal Sect for hundreds of years. It is not so easy for it to fall to the point of having its lineage cut off."

Wang Qing took the book and naturally flipped through it for a while, her pupils dilating and contracting intermittently during the process.

Even though the commotion was so small as to be almost imperceptible, it was still noticed by Yan Cheng, who was unaware of the danger.

The smile vanished from his face, and a deep, dark purple aura rose in the depths of his eyes:

"She can understand it."

"How could a mere rogue cultivator possibly understand the refined language of the Great Zhou Dynasty?"

"This person may not be from the Heavenly Corpse Path, but they certainly have an inexplicable connection to this place."

"Otherwise, seeing that Tiantong had already gone far away, how could she have remained so calm and never mentioned returning to her cave!"

His understanding of the female cultivator's intentions was clear and cold:

"This guy must want something from the morgue."

'From the very beginning, she had guessed that His Highness would definitely send someone here.'

"Her anxiety about rebuilding her foundation and her promise to give me benefits after returning to her cave were all just excuses to persuade me to bring her along."

From beginning to end, her only goal was to come to this morgue.

"But she cultivates neither cold qi nor corpse demons, so what is there in this place that she's after..."

Just as he was about to raise the Black Gold Corpse Control Ring again to force Wang Qing to reveal her true intentions for coming here, he suddenly heard a soft sigh.

A hand, as white as jade, reached out from the side and casually took the scroll from Wang Qing's hand, holding it in front of her and reading it softly.

Yan Cheng's pupils suddenly dilated as he watched the figure in snow-white robes tuck the scroll into his robes. He clapped his hands lightly in praise:

"good."

Beneath the hood, a faint smile graced the small portion of his face that was partially exposed from the shadows.

It is none other than the Holy Maiden of the Demonic Sect!
