Yin Sha Evil Spirit.

Not Yin Soul Ghosts.

Yin Sha refers to the innate spirit—Yin Sha Demon Spirit, while Evil Spirit refers to the Heaven and Earth Spiritual Treasure born by merging into the Innate Yin Sha Demon Spirit.

This object is present in the memory of the Fake Pill Demon Soul, but previous cultivators did not discover its role in Heterodox Core Formation, whether Evil Cultivator or Demon Cultivator, they only considered it as an auxiliary item to enhance cultivation.

Of course, this is related to its absolute rarity, similar to East Spring River, it exists but its role is little known. As for the most fundamental reason, according to the memory of the Fake Pill Demon Soul, those who consume the Yin Sha Evil Spirit are eroded by its Yin Sha Demon Spirit, becoming a reincarnated shell of the Yin Sha Demon Spirit.

But according to the soul memory of Qi Guan Mountain, someone solved this problem and discovered the true role of Yin Sha Evil Spirit, making it a crucial item for Heterodox Golden Core, far more important than other things.

The Golden Core Technique provides ideas and methods for condensing the Golden Core; Celestial Yin Pill, Spirit Root, Dao Foundation and the like improve the chances of Core Formation success, but if one wants to improve the quality of Core Formation, Yin Sha Evil Spirit is absolutely necessary.

Otherwise, even if your Golden Core Technique is outstanding, Celestial Yin Pill quality high, Spirit Root and Dao Foundation strong, there is a great likelihood that it will only be a Heterodox False Pill.

Once formed into a Heterodox False Pill, it equates to having no hope of Heterodox Golden Core. There are two reasons: one, to condense the Golden Core again requires Transformation Pill. Once the False Pill is transformed away, the foundation will inevitably be damaged, reducing the possibility of condensing Golden Core; two, because this world is not of the Heterodox Dao, Heterodox Cultivators gain the advantages of rapid cultivation and strong power, but correspondingly bear more burdens.

If a Righteous Cultivator possesses a Top-Grade Single-Attribute Spirit Root or merely a Top-Grade Spirit Root, the chances of Core Formation are two-in-ten. With the assistance of Tier Three Core Formation Treasure Pill and the search for a superior Tier Three Spiritual Vein that provides Spiritual Qi for Core Formation, the chances of forming a True Pill can be four to five-in-ten. Not high, but definitely not low, while for Heterodox Cultivators, under the same conditions, the chance of Core Formation is only about three-in-ten. 𝒻𝓇𝑒𝘦𝘸𝑒𝒷𝓃ℴ𝑣𝘦𝑙.𝒸ℴ𝘮

This is the situation for Heterodox Cultivators, and the reason why the Divine Fall Mountain Range has only produced one Core Formation Zhenren in the past few hundred years.

"No wonder Brother Feng would take risks to come to the Traceless Mountain Range." Wen Jiu carefully examined the memories of Demon Soul and Qi Guan Mountain, trying to discover the reasons for the rarity of Yin Sha Evil Spirit. Indeed, Qi Guan Mountain knew some, and Fake Pill Demon Soul knew some as well.

There are also two reasons, one is that the Yin Sha Demon Spirit is extremely rare, in the Innate Death Land a hundred or several hundred years can pass before one might be born; the other is that the growth environment required by the Yin Sha Demon Spirit is extremely harsh.

According to the memory of Qi Guan Mountain, in several hundred years only two Yin Sha Demon Spirits appeared in the entire Divine Extinction Thousand Peaks. One was acquired by Pei Wuxing, but it was two to three hundred years ago. Recently, another Yin Sha Evil Spirit seems to have appeared, but it is in an extremely dangerous forbidden area in the Divine Fall Mountain Range.

Even Pei Wuxing suffered serious injuries trying to acquire it, now continuously in seclusion for healing in the Little Demon Realm. Whether he got it or not is still unknown, but with nobody attempting to break through to the Golden Core Realm in Wind and Cloud Immortal City, and Pei Wuxing constantly in seclusion for healing, it seems he did not acquire that Yin Sha Evil Spirit.

In these circumstances, the Yin Sha Evil Spirit naturally becomes a rare item, something Heterodox Cultivators in Divine Extinction Thousand Peaks can only dream of obtaining. Qi Guan Mountain came here because he detected an Innate Death Land within the cave mansion.

A Innate Death Land that hasn’t been visited for hundreds of years is highly likely to contain a Yin Sha Evil Spirit.

"External Foundation Establishment’s Undying Bone has a sixty to seventy percent chance of Core Formation, in this situation as long as preparation is sufficient, there is no reason for Core Formation failure. But I’m different, I have an inferior Spirit Root, although it mutated, it’s still an inferior Spirit Root, my Dao Foundation is unclear, it’s unknown how much the success chances for Heterodox Core Formation can be increased.

If there indeed is a Yin Sha Evil Spirit present, as long as I obtain it, it can greatly enhance the chances of Core Formation, possibly elevate them to the high probability of Undying Bone, Heterodox Golden Core might be within reach..."

At this moment, Wen Jiu finally understood why Feng Jue could not disclose the matter of the Yin Sha Evil Spirit to him. Of course, Wen Jiu did not think Feng Jue was unwilling to say, as Feng Jue’s seeking him already demonstrated absolute trust, so most likely the soul within imposed a limitation, fearing he might harbor ill intentions upon knowing.

"Brother Feng, you’re really putting me in a dilemma here. If there truly is a Yin Sha Evil Spirit, should I snatch it or not?" If he decided to snatch it, Feng Jue would unlikely be able to stop him, even with the means kept secret, he wouldn’t be able to catch up to East Spring Undying Bone.

Wen Jiu fell into contemplation, not making a hasty decision, immediately accelerated his pace towards the Ancient Evil Cultivator’s Cave Mansion again. Because if there truly is a Yin Sha Demon Spirit inside, the moment the cave path is opened, the Yin Sha Demon Spirit will be detected by Golden Core Cultivators or Tier Three Great Demons in Traceless Mountain Range.

No matter how far away.

This made Wen Jiu feel like it’s not the Golden Core Cultivator sensing the Yin Sha Demon Spirit, but more like the Yin Sha Demon Spirit deliberately providing a tip-off to the Golden Core Cultivators. Because the coverage of the divine sense of Golden Core Cultivators is only roughly a thousand miles, if it can sense things ten thousand miles away, would they still be Golden Core Cultivators?

"I need to enter quickly." Wen Jiu continuously used Blood Corpse Escape, completely disregarding the consumption of corpse qi.

Three Thousand Blood Inks and Blood Demon Undying Bone are frantically devouring Yin Evil Qi to restore corpse qi, while the Yin Technique within him frantically transfers to East Spring Undying Bone. As a result, chasing took two hours, but retracing took Wen Jiu less than one hour.
