After taking Qin Yu to the Western Library Pavilion, Li Ruyan left, according to Li Ruyan, there are all kinds of things in this Library Pavilion, which can solve most of Qin Yu's doubts.

It seems that it is because ten years later it will be a hundred-year war, so there are almost few heavenly ghosts thrown into the Rakshasa Purgatory during this time period, and most of the heavenly ghosts in the library pavilion are new to the heavenly ghosts, so that there are not many heavenly ghosts in this library now, which makes Qin Yu not afraid of being disturbed.

Because the meaning of the existence of this Rakshasa Purgatory is to cultivate the Rakshasa Purgatory, there is no need to worry about the daily cultivation needs in the Rakshasa Purgatory, here, the Heavenly Ghost only needs to do everything to improve his strength.

Qin Yu spent nearly half a month reading all the books in the Library Pavilion, and I have to say that the books in the Library Pavilion were all-encompassing, outlining all aspects of the Ghost Domain, and even extending to the Nine Great Immortal Domains.

This gave Qin Yu a general understanding of the secrets of the ghost domain, but the more he knew, the more Qin Yu was puzzled.

"According to what Li Wufeng said at the beginning, the Void Blood Sea suppressed the soul of a certain Saint Realm powerhouse, and in order to refine the soul of this strong man, a terrifying formation was arranged, and the power of heaven and earth was gathered to try to refine the soul of this strong man. ”

And Li Ruyan also said that all the remnants of the souls of those who were killed in the Nine Great Immortal Domains were condensed in this Ghost Domain...... If it's true...... So, is it possible that the Nine Great Immortal Domains are also part of the formation?

This result made Qin Yu gasp, thinking back to what he had heard in the Three Thousand Dao Heavens, he couldn't imagine whose Divine Soul he was suppressing could use such a skill, and besides, the person who arranged this terrifying formation was probably also the pinnacle of achievement.

"Wait...... The heavenly ghosts are extremely yin things, and they are the remnants of the souls of those who have been killed...... The person who was killed contained an extremely heavy grievance, from which can it be concluded that the divine soul suppressed here is the existence of the extreme yang?

"Extreme Yang Divine Soul...... Whose soul will be suppressed?Is it related to the secrets in the Flood Desolate Forbidden Land?" Qin Yu thought of the Three Thousand Dao Heavenly powerhouses in his mind, but at the beginning, he thought that the Three Thousand Dao Heavens were illusory, so he knew very little about the Three Thousand Dao Heavens, so it was difficult to figure out who had been suppressed, but what was certain was that this Void Blood Sea probably had some kind of relationship with the Flood Desolation Forbidden Land.

"Well, these secrets are not what I am pondering now, and I need to do it now...... It's preparing for the Great War of the Hundred Years in ten years!" Qin Yu muttered to himself, picking up a book on the introduction of the Heavenly Ghost Body.

"The body of the heavenly ghost is condensed by the remnant soul, and the remnant soul in the body can be used only when the remnant soul is perceived and the remnant soul is transformed into the heart. Qin Yu frowned slightly.

Feel the remnant soul in the body, and turn the remnant soul into the heart?

Does this mean that you have to comprehend this remnant soul one by one, and incarnate into a remnant soul before you can use the power of the remnant soul?

"Although I don't know how many remnant souls Xing Hades used to condense the Heavenly Ghost Body for me, there are definitely hundreds of thousands...... However, most of them have been reduced to pure power, and these have no power to speak of, except for those remnants of memories that still remain...... It may be possible to use its power, such as ...... This Ancient Saint Mixed Yuanzi, Sumeru Immortal Son of Heaven......" Qin Yu's heartbeat couldn't help but speed up.

Although he didn't know what kind of existence these two people were, Qin Yu could feel the horror of the two, if he could feel the remnants of these two people...... Borrow the power of their remnants...... I can't imagine how terrifying the strength will be!

"Wait, in this ghost realm, do you devour more remnant souls...... The stronger the strength......? It can devour the remnants of the top powerhouses, and it is being perceived...... Wouldn't it be possible to increase his strength to the extreme in a short period of time?" Qin Yu thought about it, the more he felt that it was possible, and his face showed excitement and anticipation.

Suppress the surprise in your heart and continue to read.

Half a quarter of an hour later, Qin Yu stared at a passage in the ancient book, with an extremely strange expression: "Driving the power of the remnant soul, the greater the gap between the two states of mind and strength, the more dangerous it is, the heavier the soul is scattered, and the lighter one is taken away." ”

"According to this meaning, if you use the power of the remnant soul, you will far exceed your own state of mind and strength...... Will the heavy ones be scattered, and the light ones will also be counterattacked?Does this mean that if I rashly use the power of the remnants of the souls of the Ancient Sage Mixed Yuan Zi and the Sumeru Immortal Heavenly Son...... Is it possible that they will be taken away by both?" Qin Yu's face stiffened slightly.

"Indeed...... The heart is transformed into the remnant soul, which means that the heart is integrated into the remnant soul...... If the remnant of the remnant is too strong...... To some extent, the memories will dominate, and then ...... He is no longer himself, but mixed with the memory of the strong, so that even if he is not taken away, it is almost the same!"

"It seems that the state of mind has not been raised to a certain level, and he does not dare to use the power of the two easily...... However, before that, I can go to enlightenment in case I need it. Qin Yu muttered to himself.

"However, if you want to comprehend the remnant souls of the two, it is not possible to do it in a short period of time, and the top priority is to condense the power of the remnant souls...... In this way, I should be able to use the power of the remnant soul to arrange the Star Killing Array, and the Sky Slaying Sword...... It should also be able to be used, and if these two can be used, perhaps, there will be a certain amount of self-preservation. After making up his mind, Qin Yu got up, put the books back in place, and left the library pavilion.

Just as Qin Yu walked out of the library pavilion, he saw a young man with a sharp beak and monkey cheeks trotting into the library pavilion, and when he just passed Qin Yu, he suddenly stopped, not only turned his head to look at Qin Yu for a moment, but said, "Fellow Daoist, slow down." ”

In the Ghost Domain, there are two kinds of Heavenly Ghosts, one is from the Nine Great Immortal Domains, and the other is the Heavenly Ghost condensed by the remnants of the Hongmeng Battlefield.

Generally speaking, the heavenly ghosts condensed by these Hongmeng battlefields have a very high status in the ghost domain, and the lowest one is much higher than the heavenly ghosts of the nine immortal domains, after all, the remnant souls they condensed are all extraordinary, which is why the young king of heavenly ghosts will cause competition in the first place.

Although he is only a young king of heavenly ghosts, he is condensed from the remnant souls in the Hongmeng battlefield, and the remnant souls in that battlefield are all top-notch in their lifetimes, so their potential in the future is not comparable to the nine immortal realm cultivators.

Therefore, in purgatory like this Rakshasa Purgatory, the vast majority of them are monks from the Nine Great Immortal Domains, and of course, there are also heavenly ghosts with the condensation of the Hongmeng Battlefield, and they come here with only one purpose, which is to become Rakshasas!

"What's the matter?" Qin Yu asked.

This Taoist friend was ...... But the new ones in Rakshasa Purgatory?" the sharp-beaked monkey-cheeked young man asked.

"Yes!" Qin Yu's eyes narrowed slightly, and he nodded slowly.

The young man's eyes flashed with a hint of surprise, but his face was still flat, and he said, "Can you join the team?"

"Team, what team?" Qin Yu wondered.

The young man was overjoyed, and hurriedly stepped forward and said, "Ten years later, it will be a hundred-year war, if you don't join the team, you will be devoured by others immediately after leaving the Rakshasa Purgatory during the hundred-year war......"

"Therefore, the monks in the entire Rakshasa City are in groups, and only in this way can they survive the Great War of a Hundred Years......! If you join...... Every year, I can listen to Brother Wang Tao's lectures and get guidance from Brother Wang Tao...... Let's go, I'll take you to our cultivation place?"

Qin Yu's eyes flashed a different color, he pondered for a moment, and said indifferently: "Okay." ”
