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

"The Middle Elixir is the place where essence and energy gather and respond, where dust is cleared and the inner energy is stored within."

"When it is full, it overflows into the extraordinary meridians, like torrential rain flowing aimlessly into lakes and marshes. The Qi enters the eight extraordinary meridians but does not circulate, so the twelve meridians cannot restrain it."

"This signifies the completion of the Middle Alchemy!"

In the dark room, Yan Cheng sat cross-legged and silently recited the passages about mid-stage Qi Refining cultivation from the "Shang Yin Tian Corpse Path Chapter".

"Up to this point, it's not far from what Tiantong said."

"It's simply that the 'Corpse-Walking and Evil-Tracing Technique' distributed by the Emperor lacks the method for cultivating extraordinary meridians outside the main scriptures."

"The complete method of cultivating the extraordinary scriptures should involve cultivating all nine meridians!"

The eight extraordinary meridians passed down in the palace have one thing in common: none of them involve the cultivation of the brow apex.

The only meridian that can be cultivated to the center of the eyebrows is the extraordinary meridian that originates from the perineum and ascends to the Baihui point.

The mysterious aperture between the eyebrows happens to be the place where the upper dantian is opened when breaking through to the later stages.

If one has not mastered this profound secret beforehand, it will undoubtedly greatly affect the success rate of corpse cultivators in breaking through to the late stage of Qi Refining!

Yan Cheng once again cursed the inhuman Immortal Sect in his heart.

With the lineage so incomplete, what kind of sect are they trying to establish?

No, upon closer reflection, does His Highness truly hope that every mid-stage corpse cultivator can successfully break through to the late stage?

Just as the hall was pleased to see that only a few early-stage corpse cultivators could break through to the mid-stage.

Among mid-stage corpse cultivators, naturally not too many can break through to the late stage.

Otherwise, the number of middle-level servants working for the palace would decrease, and the overall strength of the corpse cultivators would become stronger, increasing the cost for the palace to manage them.

"These despicable bastards were always clamoring to kill the slow-developing corpse cultivators, but once they achieved some results, they became unhappy."

Yan Cheng opened his eyes, a cold, purple light emanating from them:

"As the superiors do, so the inferiors follow suit; that scoundrel Tiantong didn't have any good intentions either."

"From beginning to end, he never mentioned his natal charm to anyone!"

The natal talisman is an object used to suppress the Qi Palace, which has the effect of stabilizing the Dantian and increasing the success rate when breaking through realms.

According to the "Shangyin Heaven Corpse Dao Chapter", a superior quality natal talisman can enable a cultivator to master a divine technique, and it can also be effective for cultivators who have already completed a breakthrough!

A cultivator in the Qi Refining Realm has three Qi Palaces: Upper, Middle, and Lower. If each Qi Palace also contains a natal treasure, then there will be three more wondrous treasures in total.

Compared to a cultivator who doesn't even have a single protective artifact, the difference is like heaven and earth!

Yan Cheng's cultivation technique was of such high quality that he could break through steadily without the aid of any protective objects, so he didn't think much of it before.

But now that I think about it, even an ordinary talisman could increase a cultivator's chances of breaking through by half to one percent.

If the hall is truly short of people and hopes to help more early-stage corpse cultivators successfully break through, then each person should be given a protective charm!

"That's not necessarily true... Given Huang Tong's sinister nature, he certainly wouldn't give away his protective charms to the corpse cultivators for nothing."

"Even ordinary-quality talismans are beyond the reach of most corpse cultivators."

Therefore, it was decided not to mention the matter at all, so that the corpse cultivators could break through with greater boldness.

"Even with the aid of protective objects, many corpse cultivators simply couldn't succeed anyway!"

Yan Cheng was almost certain that the corpse cultivator, who progressed as rapidly as Tian Tong, possessed at least one natal artifact within his body, and of considerable quality.

The higher the quality of the talisman, the greater the boost it will provide to a cultivator's daily cultivation efficiency.

This is why, even though they are both in the mid-stage, Tendo has been able to steadily improve.

The real reason why countless corpse cultivators can only waste their time and painstakingly hone their cultivation is that they can only wait for the right moment to pass the time.

Improving cultivation efficiency is also a goal that Yan Cheng has never wavered from since the beginning of his cultivation!

He formed the Moon Wheel Mudra with his hands, quietly gazing inward at the clear, unchanging radiance of his divine consciousness.

The Moon Laurel Clear Yin Mystic Essence takes shape every night, but Yan Cheng's speed in condensing it into Upper Yin Star Qi can never keep up.

Three months have passed, and the moonlight accumulated in the Hidden Immortal Mirror is already overflowing!

For Yan Cheng, this was undoubtedly like having a mountain of treasure but being unable to spend it, a truly painful situation.

Only by increasing cultivation efficiency can the advantage of the Silver Mirror in condensing moonlight be maximized!

One way to improve efficiency is to continue receiving moonlight tempering to improve one's physical constitution.

"However, now that the Weaver Girl is no longer by my side, I cannot ascertain the exact location of the exit from the Sea of ​​Mist."

"Unless... I truly absorb the Unstable Mist into my Qi Palace, making it my natal talisman, perhaps then I will be able to sense the subtle changes in the Sea of ​​Mist!"

He had actually been thinking about this matter for a long time.

The reason for the hesitation is simple: the Unstable Mist is not a spiritual object of the Upper Yin lineage, and allowing it to occupy a Qi Palace would be equivalent to wasting an opportunity to improve cultivation efficiency.

But in this godforsaken place, where could he find any spirits to harbor?

Spiritual objects from the Taiyin lineage could be used as substitutes, but they are equally difficult to find here.

The Heavenly Moon is not bad...

Yan Cheng quickly dismissed the foolish idea that might lead him to his death.

"And the biggest problem is that I don't have the incantation to refine other spiritual objects into natal protective charms."

"Different spiritual objects require different steps and key points when refining them."

"A slight mishap during the process could result in the loss of a spiritual item, which is a minor matter; the real danger lies in damaging one's Qi Palace!"

The way in which the unpredictable fog is contained is clearly remembered in the "Hidden Mist Secret".

He himself had done some practice, but he skipped the actual refining process.

Only this method can help him locate the exit of the fog sea, receive the moonlight tempering once again, and further transform his tendons and marrow!

Yan Cheng sighed inwardly:

"Forget it, there's never been anything in this world that can have it all!"

Having made up his mind, he did not hesitate any longer and immediately focused his energy and concentration.

The boundless mist, which was being slowly collected into the Hidden Immortal Mirror, was guided downwards to the Dan Qi Mansion!

The once empty, dark room was now shrouded in a thin mist.

The mist lingers, sometimes like white clouds sinking into the twilight, sometimes like wisps of smoke rising, its origin and end unknown.

Then a moon rose from behind the mist, illuminating the room and dispelling the haze.

When Yan Cheng opened his eyes again, the purple light in his eyes was covered by a thin, almost imperceptible mist, and his divine radiance was restrained, as smooth as warm jade.

"It's done!"

After containing the boundless mist as its natal talisman, the resulting wondrous name is [Hidden Radiance].

The Unstable Mist is of extremely high status, and even the wondrous Hidden Immortal Mirror [Cave Illumination] cannot penetrate it.

Although Yan Cheng only obtained a single strand, he was able to absorb it overnight, and his own status was qualitatively elevated.

The wondrous [Hidden Radiance] that arrived alongside this figure enabled Yan Cheng to quickly comprehend the various techniques at the Qi Refining level and master the related cultivation and knowledge.

For example, the more he practiced it, the more difficult it became, giving him a real headache.

With the miraculous blessing of [Hidden Radiance], one can complete the cultivation in less than half a day!

This has nothing to do with Yan Cheng's own level of understanding, but rather it reflects the difference in status between those of higher rank and those of lower rank.

The principle is like asking a Foundation Establishment cultivator to learn a Qi Refining technique that they have never explored before.

No matter how profound the Qi cultivation techniques are, they are ultimately things belonging to the Qi cultivation level, and can never teach a Foundation Establishment cultivator to remain unable to enter the door for long!

At this moment, Yan Cheng's status has reached the peak of Qi Refining cultivators.

This means that no matter what kind of techniques he cultivates in the future, he will have a clear understanding of them from a high vantage point, and no obstacle will be able to stop him!
