The demons are completely destroyed, and the abyssal corrosion of the entire plane will end here, and then as long as there is enough time, then the plane's own purification ability can completely solve these filthy evil powers.

And Kel'thugad began to search for the memories of these demons, of course, the method is very brutal, as the undead is a race that is very good at soul manipulation, Kel'thugad's powerful and pure soul successfully broke through the demon's soul defense line with just one impact, and then directly suppressed the demon's strongest soul with that powerful soul power comparable to the legendary level, and the strongest soul that was just a holy rank easily achieved the goal.

Then he extracted the demon's memories and exported them, directly whitewashing the demon's entire soul and turning them into idiots.

The next job is to sort out useful information, after all, a lot of information in the demon's memory is useless, such as the demon's various negative emotions and other things, which will be judged as useless.

In the end, all that remains are memories such as the birth and growth of demons, the composition of the demon's race, the demons' high-level leaders, and so on.

Then Kel'thugad once again streamlined the repetitive memories to wash away, and finally made this demon book made of a large number of demon memories.

The book also introduces the problem of demons, the problem of the abyss, the problem of the corrupted plane, the knowledge of demons about the gods, and so on.

In this regard, Kel'thugad also felt that it had been sorted out, so he teleported this demon book to Wang Fan's hands through the teleportation array.

And Wang Fan also started to check it immediately after getting the book, after all, he didn't know that the great demon who could contact the abyss had died in battle, so Wang Fan was not sure that the demons he had eliminated were all of them, so he needed to check the demon's memory immediately to ensure his personal safety.

Opening the Book of Demons, Wang Fan saw the hideous demon head engraved on the first side at first sight, and it kept roaring trying to break free from the shackles of the pages, but unfortunately it was ineffective, because the materials used to make the Book of Demons were not ordinary, they were made of the skin of the desolate beast, and the freaks of the desolate beasts were born to restrain almost all creatures, and their terrifying bodies were the basic disks of their rampant universe, so the skin of the desolate beasts that wrapped this terrifying body was naturally extraordinary, and it was used to make pages of the book, not to mention trapping the negative emotions and energy of these strongest Saint-level demons, even the complete soul of the legendary great demon doesn't want to break free from the shackles of this kind of thing in a short period of time.

Therefore, Wang Fan glanced at it casually and flipped through it with the roar of the demon head (the pages of the book are like those moving newspaper illustrations in Harry Potter)

Then the second page is interesting.,It's the memory replay of the world that happened recently.,Through a large number of post-editing to delete redundant repetitive or vague memories after the formation of a whole paragraph of memory fragments.,Start from the invasion of this plane.,And then end by being caught by Wang Fan.,Wang Fan naturally took a fancy to this very quickly.,After all, this is what Wang Fan needs most at this stage!

In the following time, Wang Fan completely sank into the large number of demon memory fragments, constantly analyzing the changes in the current situation from the beginning, and constantly deducing the impact, and when he saw the picture of Lei Ying being killed, Wang Fan took a deep look at the laughing big demon, and then continued to watch.

And when he saw that the Great Demon was blocked by the two towering ancient trees one after the other, Wang Fan had already seen its ending, because in the plant plane, Wang Fan had already felt the breath of these two ancient trees, but he didn't feel the breath of this great demon, obviously

Sure enough, there was no nonsense and the three lifeforms fought directly, and the two sides continued to test each other, and from time to time there would be vines or stingers that were hit at the big demon, and the big demon sent fireballs to counterattack, and finally when the two sides could no longer restrain themselves, the battle broke out.

The Great Demon is worthy of being the Great Demon, although he needs to face two ancient trees known for their super vitality in terms of numbers, he is not afraid at all, but he launched an attack first and injured the more domineering Hideous Ancient Tree, but he obviously underestimated the horror of the vitality of the Ancient Tree, so his attack only burned half of the crown of the Hideous Ancient Tree, although it was also injured, but it was also the same egg.

The ensuing battle situation began to tilt to the side of the ancient tree, and the two ancient trees attacked one main defense and one main defense, so the great demon was exhausted and finally died, but the self-explosion that even his soul exploded before he died still brought a lot of damage to the ancient tree, and directly destroyed a large number of branches of the ancient tree that came to attack, and cut them into wooden sticks.

Then there were the memories of the demons hiding and hiding, and these were directly looked at by Wang Fan fast-forward, and after finding that there were no other demons missing, they were directly deleted.

Then Wang Fan turned the second page and came to the third page, because he knew that the demon threat was no longer there, coupled with the essence of the ancient tree, Wang Fan could already be said to have no scruples, so he began to look at the following content carefully.

The third page records the far-reaching geographical "human" cultural environment, into the eye, Wang Fan saw a red sky and the meteor shower that constantly crossed with a rolling negative atmosphere, followed by the barren earth under his feet, during which the picture continued to switch, after all, this is an integrated memory, not a single one, fortunately, these demons are basically from the same fast area of the flame demons, so through the patchwork of the complete abyss Ten Thousand Demons Plain flame area terrain map is almost put together.

Subsequently, Wang Fan saw the figures of other demons, such as the fire demon who lived in the negative energy volcano, the terror demon who lived on the plain, I like to fly in the sky winged demons, like the magic flower and demon tree that ambushes motionless, etc., and in the later memory, I saw some strange demons with other attributes, such as the ice demon, they are the nemesis of the fire demon, a kind of twisted ice block demon formed entirely by twisting the will, they look beautiful, after all, the whole body is shiny, but in fact they are more terrifying than the fire demon, freezing the prey, and then torturing the prey with extreme cold, constantly letting it freeze the parts on the body, for fun.

There are also some very peculiar ones, such as mimicry demons, at first Wang Fanna didn't see what the hell it was, but finally after seeing it simulating again, he realized that after a long time, it turned out that this guy was a transformation expert! It's like a variety of monsters in Pokémon in the previous life, and the ability can change into any form.

There are also things such as Shadow Fiend: lurking in the shadow of its prey, it is a natural assassination and ambush expert Blood Fiend: a demon poison who manipulates the blood in the body of any living being: the whole body is like a bulging ball of flesh, the way of action is to roll, and it is still the kind that releases poison while rolling

Anyway, Wang Fan is on this third page, and he suddenly changed from knowing nothing about the abyss to having a good understanding of the abyss.
