The Netherworld Ghost King described it with grandiosity, but the more Yun Sheng listened, the more she felt something was amiss.

"Ghost King, if this magic is truly so powerful, why would you teach it to me for no reason? There should be plenty of people in the Netherworld eager to learn it, right?" Yun Sheng was the least likely to believe in such luck falling from the sky.

In the Human World, generally speaking, only Basic Magic and Low-level Magic are widely circulated on the market; Intermediate Magic Scrolls are already priced very high.

As for Advanced Magic above the Intermediate level, it is even more priceless; even if available, it comes at astronomical prices, worth ten thousand, or even tens of thousands of Purple Gold Coins.

Holy Domain Magic is even more rare. On the Wuji Continent, it is only found in the Magic Temple or the Mainland Magic Elite Camp, existing in the form of a Magic Tree or Magic Stele.

This situation is likely similar in the Netherworld.

The Netherworld Ghost King is either Near God level or actually a Divine-level existence; something he highly praises might be unparalleled throughout both the Human and Netherworld realms.

This is also why Yun Sheng doubted why the Netherworld Ghost King was insistent on teaching her magic.

Despite being her nominal "stepfather," the Ghost King teaching her such powerful magic for no reason must entail some mystery.

"Ahem, you little girl, how can you judge a gentleman’s heart with a petty one? Okay, let me be clear early on, this kind of magic isn’t something just anyone can cultivate. Moreover, to achieve the effect of god-slaying, you must attain a cultivation level similar to mine. The most critical point is that this magic is just a Secret Magic I momentarily comprehended, and it only has the first half. The latter half, I haven’t comprehended yet," the Netherworld Ghost King’s handsome face indeed showed a hint of embarrassment.

In fact, he hadn’t planned on telling Yun Sheng so much.

But who would have thought this girl was so astute, seeing through the flaw at a glance.

To put it plainly, the Netherworld Ghost King approached Yun Sheng because he intended to use her as a test subject to see how far she could cultivate this magic, or whether she could potentially complete this Secret Dark Magic in the future.

"..." Yun Sheng and Bo Bo simultaneously gave a look of disdain.

A gentleman indeed, if the Netherworld Ghost King is a gentleman, then no villains exist in this world.

"Ghost King, so what you’re saying is, I might not even be able to cultivate your ultimate skill, an incomplete Secret Magic. The potential danger is evident," Yun Sheng, ever cautious, would not rashly learn a magic, no matter how powerful, if there remained any inherent danger.

Yun Sheng had also heard many rumors about a mage being severely injured or having their Magic Soul damaged, unable to practice magic again due to greed for a powerful but incomplete magic.

Therefore, even knowing this so-called God Slaying Magic is indeed powerful, Yun Sheng still needed to consider carefully.

"No, no, no, you certainly can learn it, because this Secret Magic can only be learned by mages possessing multiple Magic Souls. Talking about it, Ye Beiming could also learn it, but he has one fewer Magic Soul than you, so you should find it more effective to study. Although this Secret Magic isn’t complete, you could comprehend it yourself during its use," the Netherworld Ghost King still somewhat admired Yun Sheng’s talent.

"The more Magic Souls, the better the learning effect? Is there such magic?" Yun Sheng was even more suspicious.

"Let me put it this way—I was once a Four Element Mage," the Netherworld Ghost King straightforwardly revealed his Magic Soul.

Compared to Yun Sheng’s Six-Colored Magic Soul, the Netherworld Ghost King’s Magic Soul was much larger.

Yun Sheng felt the sky suddenly darken.

It seemed as if an area of one square mile was shrouded under the Netherworld Ghost King’s Magic Soul. 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

Just the appearance of the Magic Soul brought a terrifying magic wave capable of destroying the heavens and the earth.

Ordinary mages, upon encountering this wave, would involuntarily feel fear, significantly affecting their use of magic.

However, there was a discrepancy with the said Four Elements Magic Soul; the Netherworld Ghost King’s current Magic Soul was black, indicating he was merely a Dark Mage.

"You must be wondering why I only have one Magic Soul now—because I converted the remaining three Magic Souls into Dark Magic Souls, which is why my Magic Soul is now so powerful. This is also how, over twenty years ago, I was able to break through to the Divine-class," the Netherworld Ghost King’s words made Yun Sheng’s expression grow serious.

She suddenly realized that what the Netherworld Ghost King was about to say might directly relate to her future magic training.

On the continent, multi-element mages, though rare, generally possess outstanding talent and achieve greater success than single-element mages.

This view is universally accepted across the Divine, Human, and Netherworld realms.

The Netherworld Ghost King was no exception at the start of his cultivation, but upon reaching the Realm of Magic God, he realized this notion was incorrect.

At the Realm of Magic God, any magic used was powerful enough to move mountains and fill seas; however, the magic’s consumption was equally immense.

In contrast, multi-element mages experienced more severe mana exhaustion when using multiple magic types.

Conversely, single-element mages, specializing for years in one type of magic, excelled in its application and control.

This created a situation where, even with both being Magic Gods, single-element mages were stronger than multi-element mages.

"Let me tell you plainly; after breaking through the Divine-class, I went to the Divine World seeking a method to condense Qingcheng’s Magic Soul. There, I met a Middle-level God, a single-element mage. In that battle, I was severely injured. That made me reflect deeply, returning to Ghost Water Creek, pondering for three years, and finally understanding this special Secret Magic," the Netherworld Ghost King candidly shared his past experiences with Yun Sheng.

For a strong individual like the Netherworld Ghost King, a defeat was undoubtedly a disgrace.

At that time, the Netherworld Ghost King and the Middle-level God were similarly matched; however, the Netherworld Ghost King, being a multi-element mage, was exhausted at the critical moment, while the other, possessing a sect’s divine artifact, ultimately defeated him.

The proud Ghost King attributed a large part of his failure to his multi-element Magic Soul, eventually leading to the comprehension of Secret Magic and forcibly converting his Magic Soul into Dark Magic Souls.

This transformation caused the Netherworld Ghost King’s Divine Power to progress rapidly, ultimately reaching the strength of an Upper God.
