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

"The Chapter on the Corpse Path of the Upper Yin Heaven".

This method is both the starting point of Yan Cheng's cultivation path and the true path to enlightenment that leads directly to the level of embracing the elixir.

Some time ago, he had keenly realized that the words "Heavenly Corpse" in the name of the cultivation technique were the same as the name of the Heavenly Corpse Dao lineage.

The saint's words now show that this was no coincidence.

The predecessors of the Heavenly Corpse Path unexpectedly obtained a portion of the inheritance of the [Upper Yin] Path, and based on this, they established a great lineage that has been prominent in the northern foothills for hundreds of years.

Despite the fact that the Heavenly Corpse Sect has been completely wiped out, the fact that a sect could survive the Great Zhou Dynasty's suppression at its peak, successfully survive until the fall of the Zhou Dynasty, and then force the Taiyin Immortal Sect to go all out to exterminate it, proves the Heavenly Corpse Sect's worth back then.

According to the judgment of the cultivators in the hall, the rise of the Heavenly Corpse Path originated from what was obtained in the Moon-Covering Palace.

If the Hall of Longevity can obtain enough benefits from the Moon-Shielding Palace, could it also grow to the same level as the Heavenly Corpse Path of yesteryear?

Thinking of this, Yan Cheng became even more certain:

"These guys are definitely acting alone, keeping it from the sect..."

"Who knows if the sects are happy to see the Longevity Hall's strength suddenly increase so dramatically? Among the Five Courts and Twelve Halls alone, I'm afraid many powerful figures wouldn't want to see this happen!"

The saintess said:

"It seems that the sect also sent people to search for traces of Biyue Palace, but after confirming that the lineage there was very likely unrelated to the Taiyin sect, they gave up the idea."

"If it were merely the inheritance of [Cold Qi] and [Netherworld], it would not be enough to attract the attention of the sect."

"As for the [Upper Yin]... in this world where the essence of the sun and moon has been exhausted, it is a dead end that cannot be cultivated."

Yan Cheng's heart stirred:

What does this mean?

The saintess remained silent for a long while before finally speaking:

"The records of this path in the palace are extremely scarce, but Master once mentioned that the Upper Yin Path is the Path of Stars, and the most important stars in the world are Taiyin and Taiyang."

"If the images of these two paths cannot be gathered together, it is impossible to teach this path completely."

"The sect may still have the Moon Laurel Pure Yin Mystic Essence that can be used, but this Great Sun Radiant Yang Golden Essence..."

She smiled faintly:

"This item can only be used by Foundation Establishment cultivators of the Sun Path to absorb its energy, and they must be cultivating a specific Immortal Foundation."

"For example, the only solar legacy in the palace, the [Light Prism]."

Her figure slowly transformed into countless mirror-like surfaces and vanished, leaving behind a single, light sentence:

"Junior brother is a smart man; he should understand what I mean."

The room was completely silent.

Yan Cheng took a deep breath and immediately used [Insight] to confirm that the Holy Maiden had indeed left.

Only then did he feel relieved and begin to ponder the deeper meaning behind the other party's words.

The Holy Maiden told him so much for one purpose only: to let him know that her importance in the palace was far greater than Huang Tong's.

As long as the Lord of the Hall of Longevity does not give up collecting the essence of the sun and moon, he will surely help the Holy Maiden successfully establish her foundation.

In contrast, Huang Tong, who seemed to have the upper hand, was actually cultivating the [Netherworld] path, which was not valued by the sect.

Even if both of them reach the Foundation Establishment stage, Huang Tong's importance would still be incomparable to that of the Holy Maiden.

But that's assuming Huang Tong has no intention of switching to another path.

Yan Cheng understood perfectly:

Why did she bring up the matter of the "upper abdomen" with me?

"That's to remind me that as long as Huang Tong hasn't reached the Foundation Establishment stage, there's still a possibility of him changing his cultivation path!"

While the concept of "Upper Yin" may seem ethereal and elusive, who can be certain that the Palace of the Hidden Moon doesn't possess the inheritance of "Cold Qi" or even "Taiyin"?

"Since the Holy Maiden regards me as a Taiyin cultivator, her words are a reminder that even the slightest possibility of Huang Tong changing her path is a risk neither she nor I can bear!"

He had long noticed that the true disciples in the Hall of Longevity were all intentionally avoiding the same path of cultivation as others.

Zhong Tianying cultivates [Flowing Fire], the Holy Maiden cultivates [Sun], Huang Tong cultivates [Netherworld]...

Judging from the frustrating situation of the corpse cultivators in the hall, within the same path, lower cultivators are resources that higher cultivators can take and use at will.

If it weren't for the corpse cultivators' hard work and continuous offerings of Yin Corpse Fiends, Huang Tong would probably still be in the early stages!

"In the Holy Maiden's eyes, Huang Tong and I are potential rivals. Whoever achieves Foundation Establishment first will find the other in a very precarious situation."

"But to think that I'd risk killing Huang Tong just because of this is really wishful thinking."

Yan Cheng didn't intend to kill Huang Tong; rather, he planned to kill her slowly, deliberately, and strategically.

He would need to cultivate to at least the late stage of Qi Refining to have a chance of defeating Huang Tong.

So, can I break through to the late stage of Qi Refining before heading to the Moon-Covering Palace?

Actually it is possible.

Unlike Chen Xiang and the others, who had already opened their eight extraordinary meridians, he was prevented from advancing due to the emperor withholding the method of opening the upper elixir required for breaking through to the later stage.

The "Shangyintian Corpse Path Chapter" has a complete set of techniques, paving a broad road for cultivators to reach higher realms.

The problem lies in two points.

First, he has not yet found anything suitable to serve as a town-building object for Zhongdan.

To break through to the late stage of Qi Refining, one must mobilize true Qi to impact the Qi Mansion between the eyebrows.

The requirements for the stability of the second Dan Qi Mansion are much higher than when breaking through to the middle stage.

If given a choice, Yan Cheng would naturally prefer to attempt a breakthrough only after accommodating the talisman.

But where can he find a talisman that is both in line with his path and has a corresponding method of containment?

Moreover, Yan Cheng did not want the quality of the second item to be too much worse than that of Wudingwu.

If the wondrous treasure he obtained was far inferior to [Hidden Radiance], he knew he would definitely feel cheated, which would greatly affect his Dao heart.

Even though he knew in his heart that striving for perfection in everything would inevitably lead to stagnation, he could not erase the thought of making his own path as perfect as possible.

In this section, we can only hope that the Moon-Hidden Palace contains suitable spiritual objects and the corresponding methods for containing them.

When all else fails, he is prepared to forcibly incorporate the soon-to-be-forged spirit sword [Cloud Breaker] into the middle core!

Secondly, there's the innate Qi, which helps increase the success rate of Foundation Establishment.

Yan Cheng sat cross-legged before the coffin, his mind in turmoil:

"The Mysterious Scripture of Yin-Yang Supplementation and Harmony."

"Although this dual cultivation method is prepared for cultivators in the late stage of Qi Refining, it also mentions that if a cultivator can use this method when they reach the peak of the mid-stage, they can then use the primordial Qi condensed in the middle dantian to break through to the upper dantian."

"The newly formed Upper Dan Qi Palace will possess a spiritual sense strength far exceeding that of cultivators at the same cultivation level, and this enhancement will remain effective even after Foundation Establishment!"

"However, this method also has requirements regarding the lineage practiced by the partners. My own lineage is Yin, so the other person must practice a Yang lineage."

Otherwise, isolated yin cannot grow, isolated yang cannot generate, and the primordial qi will surely vanish like a bubble!

However, within this Hall of Longevity, the only Qi cultivators practicing Yang techniques are...

For a moment, Yan Cheng's expression became strange.

Damn it, am I really going to have to cultivate with the Holy Maiden?
