Hearing Anivia’s answer, Roy was stunned.

Of course, he knew that the blood of frost demons could create undead creatures, but he really did not expect that someone would especially hunt down frost demons just for this reason.

Most living creatures had blood in their bodies, and the blood of most creatures only existed to maintain their nutrients and did not have any special effects. But demons had strange characteristics in their blood due to the chaotic and dark magic power in their bodies.

These characteristics were usually reflected in other weaker creatures such as humans, animals, and so on. When these weak creatures received demon blood, they would be corroded by the demon blood, causing their bodies to undergo a tremendous mutation.

It was not only the blood of frost demons that could create undead. In fact, the blood of other demons would also create special monsters, such as that of spider demons. Although Roy had not seen it with his own eyes, it was said that if human women received the blood of spider demons, there was a certain chance that they would turn into a monster called ‘arachne’. This monster inherited the ability of spider demons to spit silk, and it was also known as a weaver woman… Its appearance was very similar to that of the Spider Queen Lolth.

In addition, there were demon races that could turn humans into vampires and werewolves. Roy did not know which demon races these races were, but he knew.

Furthermore, Roy had once chatted with Julia about sea demons, and she had said that the blood of sea demons would also contaminate other creatures. The sirens in human legends seemed to be due to sea demons contaminating humans.

And the most famous sea demon was probably Demon King Leviathan…

In short, because of the powerful aggressiveness of demon bloodlines, animals that received the bloodlines in the Abyss would often turn into all kinds of monsters. Because they lived in the Abyss and had a higher acceptance of dark power, the chances of mutations were relatively high, and they could pass it on to their offspring. The acceptance of species in other worlds was relatively low, but once they accepted them, there would be immense mutations. The legends of various monsters in the human world more or less had the shadow of demons behind them…

Of course, this was also related to demons using their bloodlines everywhere. Especially in recent times, the bloodlines of any demon were actually very mixed…

The blood of the frost demons could produce liches. Roy was an example. But this success rate of creating a lich was usually low. Moreover, it was only possible for the dead to receive the blood. It was extremely difficult for living creatures to withstand the intense cold power of frost demon blood. Cassandra had turned into a lich because she received Roy’s blood, but she had been killed beforehand.

The exact origin of the first lich was unverifiable, but it was precisely because frost demon blood had such power that more and more liches were born. In fact, many subsequent improvements in the efficiency of lich transformation were not due to frost demons but developed by the human mages themselves. They found that the transformation rate was too low when directly bearing frost demon blood. In order to achieve immortality, they ritualized the transformation process and added more materials to match frost demon blood, thereby increasing the success rate of transformation.

Now, not only did Roy hear that people were especially hunting frost demons to obtain their blood, but they were also demons. He was stunned about this.

Of course, he could understand what Anivia meant about creating an undead army. Liches were high-level undead, so they naturally had the ability to control low-level undead. If someone could mass produce a large number of liches, they could naturally control more undead. And undead that did feel pain or fluctuate because of any emotion were always the best soldiers.

“Hunting frost demons? Even if they need frost demon blood, why won’t they cooperate with frost demons?” Roy frowned. “Why must they kill frost demons?”

Anivia glanced at Roy and snorted. “Osiris, you should have used your blood to create a lich, right? Then you should know that the strength of the liches produced by different amounts of blood is different!”

Roy nodded. This was true. When he created Cassandra, she was not very strong. Her following growth was through her own accumulation and absorbing the death aura left behind by Rafaro, maturing step by step. Roy had tried to create some liches in the Darksiders world, but without exception, they were not too powerful.

“Gathering all the blood in a frost demon’s body can basically create a lich that is as powerful as the frost demon!” Anivia explained. “If the person who received the blood was a powerful mage before they died, then they have a certain chance of retaining their magic power and transforming into a lich stronger than this frost demon… But the problem is that even if we are demons, we will still die if all the blood in our bodies flows out. We can’t possibly use all our blood on one lịch!”

“Understood!” Roy nodded. “That’s why cooperation is impossible for frost demons!”

“That’s right!” Anivia said. “Even if we can regenerate our blood, the total amount of magic power in our blood will not change. Even relying on a buffer time to extract twice the amount of blood from a frost demon, the final result is the same as directly squeezing out all the blood in the demon. So those demons are using the most extreme method and directly obtaining the blood by killing frost demons.”

“When did you meet them?” Roy asked.

“About fifteen years ago…” Anivia sighed. “As one of the few remaining frost demon lords in the Abyss, I didn’t use to live in this territory but in a larger and more beautiful one of extreme cold. Other demon lords couldn’t stay in such a territory at all, and only we frost demons would choose to live there. I lived there very comfortably, and many frost demons submitted to me. But one day, that group of demons suddenly appeared in my territory and killed most of my residents. I led my people to resist, but I ultimately failed…” He pointed at the wound on his abdomen. “While escaping from my original territory, I was injured by a rift demon lord. I’ve been recovering in the ice coffin for fifteen years, but I haven’t fully recovered. In order to avoid their pursuit, I can only choose this much smaller and dirty frost territory as a refuge. Those demons chose to start with attacking the larger fragment worlds. I later found out that the other frost demons with similar territories were all attacked and perished…”

At this point, Anivia said to Roy self-deprecatingly, “In fact, you and I may be the only two remaining frost demon lords in the entire Abyss…”

“What happened in the fifteen years since?” Roy tapped his sharp nails on the armrest and asked thoughtfully, “Are those demons still attacking frost demons?” “I don’t know!” Anivia shook his head. “I’ve been carefully hiding. I don’t have many people, so I haven’t heard much news. But over the years, I haven’t been disturbed much. It seems that they’ve disappeared after that wave of attacks fifteen years ago. Perhaps they’ve already gathered enough blood and no longer need any…”

“Where did those demons come from?” Roy asked. “Since they gathered so many demon lords, there should be rumors about them in the Abyss.”

“Unfortunately, I don’t know much!” Anivia said. “I only know that the amount of frost demon blood they obtained should be enough to create a powerful lich. If you want to investigate, you can start from this.”

A powerful lich? A lich king? Roy’s heart skipped a beat. Lich King Ner’Zhul? F*ck, are the demons who attacked Anivia the Burning Legion?! Is there really a Warcraft world in the Infinite Worlds?

The so-called Warcraft world and so-called Void power was only a nonsense story Roy had spouted when he was facing the Four Horsemen of the Apocalypse in the Darksiders world. But as he learned about more worlds, he found that his prophecy had become true…

Anivia saw the strange expression on Roy’s face. “It seems like you know something about them?”

“I don’t know if it’s…” Roy deliberated over his words. “After all, I haven’t encountered these demons you mentioned before. Perhaps I guessed wrongly…”

“Hmph, don’t worry. Even if you know their origin, I won’t let you say it because I won’t seek revenge on them!” Anivia said. “The power of those demons isn’t something a demon lord like me can contend with unless I can find a demon king to support me…” Roy looked at Anivia in surprise. This guy is really speaking from his heart.

However, Roy had almost finished asking what he wanted to ask, so he did not intend to stay any longer and got up to leave.

Seeing that Roy really did not have any intention of taking his territory, Anivia secretly heaved a sigh of relief and personally sent him out. Before Roy left, he said, “Before I recover, I don’t intend to return to my original territory. But Osiris, you can try to find the territories left by other frost demon lords. It depends on your luck whether you can find them.”

Roy nodded and did not say anything else. He flew into the sky and left this fragment world…
