The Netherworld Ghost King described the sky, but the more Yun Sheng listened, the more he felt that something was wrong.

"Ghost King, if this magic is really so powerful, why did you teach it to me for no reason? There should be more people in the underworld who want to learn, right? "What Yun Sheng doesn't believe the most is such a good thing as pie in the sky.

In the human world, generally speaking, only basic magic and low-level magic will be circulated in large quantities on the market, and intermediate magic scrolls are already extremely expensive.

As for the high-level magic above the intermediate level, it is even more priceless, and even if there is, it is sky-high, worth tens of thousands, or even tens of thousands of purple gold coins.

Further up, the magic of the Holy Realm is very rare, and on the Wuji Continent, only the Dharma Temple or the Continent's Magic Elite Camp will exist in the form of a magic tree or a magic stone tablet.

This situation must be similar in the underworld.

The Netherworld Ghost King is a near-god or a god-level existence himself, he is full of praise, I am afraid that looking at the whole person and the underworld, it is a peerless existence.

It was also because of this that Yun Sheng wondered why the Netherworld Ghost King insisted on teaching her magic.

Although the Netherworld Ghost King is her titular "stepfather", there must be something strange in teaching her such powerful magic for no reason.

"Ahem, you little girl, how can you be jealous of the belly of a gentleman with the heart of a villain. Well, the emperor will make it clear in advance, this kind of magic is not something that anyone can cultivate, and in order to achieve the effect of slaughtering the gods, it is necessary to achieve a cultivation similar to that of the emperor, and the most important point is that this kind of magic is only the mysterious magic that the emperor has comprehended for a while, and it only has the first half, and the second half, the emperor has not yet comprehended it," the handsome face of the ghost king really floated with embarrassment.

Actually, he didn't want to tell Yun Sheng so much before.

But who made this girl so shrewd, she actually saw the flaws at a glance.

To put it bluntly, the Netherworld Ghost King approached Yun Sheng just to use her as a guinea pig to see how far she could cultivate this magic, or whether it would be possible to complete this mysterious dark magic in the future.

"......" Yun Sheng and Bo Bo Yang made a look of disdain at the same time.

It's also a gentleman, if the ghost king is a gentleman, there will be no villain in this world.

"Ghost King, in this way, I may not be able to cultivate your mastery, and there is an unfinished mystical magic, the danger of which can be imagined," Yun Sheng is calm by nature, even if she knows that this magic is powerful, as long as there is still a trace of danger, she will not rush to learn.

Yun Sheng has also heard a lot of rumors that a certain magician has learned an incomplete magic because of his greed for powerful magic, and he will be seriously injured at best, and his soul will be directly damaged in the worst case, and he will never be able to practice magic in the future.

Therefore, even if Yun Sheng knew that this so-called god-slaughtering magic was really powerful, she still had to think about it carefully.

"No, no, no, you must be able to learn, because this mystical magic can only be learned by magicians with a variety of magic souls, speaking of which, Ye Beiming can also learn it, but his magic soul is less than yours, so you should learn it better than him." Although this mystical magic has not been completed, you can comprehend it by yourself while using it," the Nether Ghost King still has some appreciation for Yun Sheng's talent.

"The more Dharma souls, the better the learning effect? Will there be magic like that? Yun Sheng was even more skeptical.

"Let's put it this way, in fact, this emperor was also a fourth-line magician," the Netherworld Ghost King simply sacrificed his magic soul.

The Demon King's soul is much bigger than Yun Sheng's six-color soul spirit.

Yun Sheng only felt that the sky suddenly darkened.

It seemed that within a radius of one mile, they were all shrouded in the magic soul of the Netherworld Ghost King.

As soon as the magic soul appeared, there was a terrifying magic fluctuation that could destroy the world.

Ordinary magicians, as long as they encounter this fluctuation, they can't help but feel fear, and even when they use magic, they will be greatly reduced.

It's just that there are some discrepancies with the four-line magic soul that the Nether Ghost King said, and the Netherghost King's current magic soul is black, which means that he is just a dark magician.

"You should also be very curious, why this emperor only has one series of law souls left, because this emperor has transformed the remaining three series of law souls into dark law souls, so my current law soul will be so powerful. This is also why I was able to break through the mystery of the god level more than twenty years ago," the words of the Netherworld Ghost King made Yun Sheng's expression solemn.

She suddenly realized that what the Nether Ghost King was going to say next would most likely be directly related to her future cultivation of magic.

As a rare multi-line magician on the mainland, they are generally talented, and their future achievements will be much higher than that of single-line magicians.

This statement is consistent in both gods, man, and the underworld.

The Nether Ghost King was the same when he first started cultivating, but as the Nether Ghost King broke through to the Law God, he found that this statement turned out to be wrong.

Because, when you reach the realm of the god of law, any kind of magic used is powerful enough to reclaim the sea and move mountains, but in the same way, the magic consumption will be even greater.

In contrast, multi-line mages also have a more severe depletion of mana after using multiple spells.

On the other hand, the single-line magicians are the opposite, they have been practicing the first series of magic for many years, and they are also better at using and controlling magic.

In this way, a situation is formed.

In the case that they are both Dharma gods, the two are at war, and the strength of a single mage is stronger than that of a multi-line mage.

"The Emperor also simply told you that at the beginning, after breaking through the God Rank, the Emperor once went to the God Realm to find a way to condense the soul of the law for Allure. But in the Divine Realm, the Emperor met a mid-ranking god in the Divine Realm, and that person was a single magician. In that battle, the emperor was seriously wounded. It is also for this reason that the emperor learned from the pain, returned to the ghost water stream, pondered for three years, and finally comprehended this special mystical magic, "The ghost king did not hide it, and directly told Yun Sheng what happened to him back then.

For a strong person like the Nether Ghost King, a failure is undoubtedly a very humiliating thing.

Speaking of which, at that time, the strength of the Netherworld Ghost King and the median god was about the same, but because the Netherghost King was a multi-system magician, at the last moment, the mana was exhausted, and the other party, because he had a master's artifact, finally defeated the Netherworld Ghost King.

The Ghost King was so proud, he attributed a large part of his failure to his multi-line magic soul, and finally comprehended the mystical magic, and forcibly reversed his magic soul into a dark magic soul.

It is also because of this that the divine power of the Netherworld Ghost King has increased by leaps and bounds, and he has finally reached the strength of a superior god.
