After taking the two books, the two big men stood up and faced the square, and the soldiers in the square raised their weapons and let out an earth-shattering shout, and the strange light in the strange man's eyes seemed to soften a lot, which seemed to be a look of relief.

The picture gradually blurred, zuihou shattered, the huge square and those strange people were gone, Ye Ling returned to the Shadow Soul Tower again, as if he had just watched an immersive four-D movie, it was very real, everything that happened just now was vivid, but he couldn't fully figure out what was going on.

At this time, the Fox Demon Empress smiled and said: "Hehe, so that's the case, I know, the Book of Netherworld and the Book of Shadow Souls are not only related, but also the most closely related, they are originally the same book, but they were separated by the legendary lord and became sisters!"

Ye Ling could only barely recognize the words of the legendary era, but he couldn't understand them, while Julie learned many things from the strange man's mouth.

Ye Ling was stunned: "Weishenme, he wants to separate the book that was originally one?"

"For his two sons!" Julie said lightly: "The one wearing the sealed armor is the earliest lord of the legendary era, and he is also the winner of the broken divine thoughts after the great war of the gods. This Wraith Emperor has a brilliant life, no one dares to offend, until the end is approaching, he intends to pass on his power to future generations, what we have just seen is the handover ceremony of the legendary lord, the other two on the high platform, are his sons, respectively obtained the title of Hades Emperor and Soul Emperor, half of the territory, and most of the Wraith Soul Liliang mystery. ”

"Half of the mysteries?" Ye Ling said puzzledly: "In this case, wouldn't it be weakened, can't the two of them cultivate all the liliang mysteries?"

"Yes, but this will have serious consequences, before the death of the Wraith Emperor, he compiled a book with his divine thoughts, the Book of Wraiths, hoping that the heir can obtain his own Liliang and continue the hegemony for generations to come. However, after writing this book, he hesitated, because his two sons were boundless in their ambitions and would not be willing to submit to others, even if it was his brother who stood in the way. If the two of them practice the Book of Wraith together, even if they are brothers with similar talents, they will also have a strong and weak score, and the strong side may kill each other with their brothers in order to dominate the territory, in order to avoid this from happening, the Wraith Emperor Zuihou decided to split the divine thoughts and the mystery of the gods Liliang that he comprehended, and the Book of Wraith was also divided into two volumes, which are the Book of Netherworld and the Book of Shadow Souls. ”

After a pause, Julie continued: "In addition, he also deliberately left a flaw in the two books, and this flaw is recorded in the other book, and only those who practice the other book can help the other party solve it, so that they have to rely on each other, limit each other at the same time, but also help each other, and they can always be united and harmonious, so as not to cause brothers to turn against each other in order to fight for power!"

Ye Ling finally understood now, and couldn't help but sigh: "That Wraith Emperor has good intentions, Sister Julie, the flaw of the Book of Netherworld should be the Shadow Soul Heart Demon, right?"

Julie nodded, "That's right, that's why the Book of Netherworld has that thaumaturgy that doesn't seem to have much effect on this book, in fact, it's prepared for the Netherbook." ”

Ye Ling thought of something again, and his face changed slightly: "In this way, isn't there a flaw in the Nether Book?"

Thinking that Vieri was corrupted by the Shadow Soul Heart Demon, his mood changed greatly, and even the former Cardinal Egrus, who had been friends with him for decades, was killed in a vain attempt to seize the Holy See, he was very worried, that flaw seemed to be serious, otherwise the Soul Emperor and the Hades Emperor would not be so scrupulous.

Julie groaned for a moment and said, " There must be, but it shouldn't be so easy to appear, such as the Shadow Soul Heart Demon, there are not many examples of the Dark Holy See, which shows that when the cultivation of the two books is not very home, the probability of that defect breaking out is very low, and the Shadow Soul Heart Demon rarely appears even in the high-level, because even the high-level of the Holy See is still too weak compared to the two legendary lords of the Soul Emperor and the Hades Low back then, and when it comes to their situation, the defect is easy to explode, with your current level of cultivating the Netherworld, if it is not very unlucky, the probability of that flaw breaking out and winning the jackpot is about the same！”

Ye Ling smiled bitterly: "That's the way it is, but, Sister Julie, this flaw is like a time bomb, which makes me very uneasy." ”

Julie smiled: "Hehe, now that you are the Pope of Darkness, what are you worried about, we can find the flaws of the Book of Nether and the solution from the Book of Shadow Souls, even if the flaws really show signs of outbreaking, you can ask Lucy to help you solve it." You're so lucky, if you hadn't come to the Dark Holy See, I wouldn't have known that the Nether Book still has such a dangerous element buried!"

The Fox Demon Empress asked Ye Ling to turn to the Zuihou page of the Book of the Netherworld, and after condensing her spiritual power through Ye Ling's body as a medium, she looked at it for a while and said: "The flaws of the Book of Netherworld are similar to the Book of Shadow Souls, and cultivators may produce a Soul Confusion, but the Soul Confusion of the Book of Netherworld is different from the Shadow Soul Heart Demon, and it requires a cultivator of the Book of Shadow Souls to unravel it. Of course, if you cultivate both the Book of Shadow Souls and the Book of Netherworlds, then you will be able to solve yourself!"

Ye Ling originally just planned to learn a little bit to pretend to be a dark pope, but now Jihua has undergone some changes, and he asked tentatively: "Sister Julie, do I really want to study deeply, cultivating the Nether Book will consume a lot of my energy, and now there is another one, I'm afraid it will be unbearable, anyway, Lucy and they can also learn that technique, if there is really a problem, just let her help." ”

Julie disagreed: "This is not as simple as making up for the shortcomings, you must know that the Book of Netherworld and the Book of Shadow Souls are originally one, and they have complementary effects, if you want to study the Book of Shadow Souls, not only will it not take up more time, but it may even be more efficient than a single cultivation, haven't you found that when these two books are combined and you read them at the same time, the consumption of spiritual power is reduced?"

Ye Ling asked: "Yes, it's really like this." ”

"That's fine, so, don't worry about your energy, from today onwards, take the cultivation of the Book of Shadow Souls as one of your compulsory courses," Julie smiled, "Maybe, you will become the second Wraith Emperor!"

Ye Ling smiled dryly: "Sister Julie, you really know how to joke!"

Having said that, Ye Ling was very interested.

No one has been able to study these two books at the same time since the first Legendary Lord, and what happens when they merge into one and become a complete Wraith Book to cultivate at the same time?
