Roy used the method of soul employment to summon hundreds of low-level demons from the upper levels of the Abyss and handed them over to Benia to lead them to begin building a new demon city.

In fact, Roy could directly create the demon city by himself with the flowing brightness flames, but he did not do so. Instead, he let the demons build it because only demons could build pure demon-style buildings. On the frozen soil and icy plain, digging soil and rocks was very energy consuming. But this time, the demon worm had contributed greatly. With its powerful digging ability, it placed the soft underground soil in its mouth and allowed the demons to have construction materials.

In Roy’s plan, the size of the new demon city would reach about five square kilometers. Unlike the single castles that high-rank demons occupied, this time, it would be a real small city that covered the underground volcano and the nearby areas. In the outermost region, Roy would personally use his frost magic to build a tall ice wall for the city wall. At that time, he would drain magma from the volcano and use it in a moat.

This would be a spectacle where ice and lava existed at the same time. Even in the entire Abyss, such an environment was rare.

And Roy named this new demon city ‘Frostfire City’…

It was naturally impossible to build such a large city overnight. The construction period would last at least a year, but Roy had plenty of time now, so he was not in a hurry and took it slow.

In the short term, Roy did not intend to go to another world. First of all, he had obtained a lot of souls in Ashan this time, more than sixteen million. So many souls were enough for him to consume for a long time. Second, even if he wanted to go to another world, he could not go for the time being. As a demon lord, he now needed to pay a considerable price to resist the world repulsive force. If he had no effective way to resist the repulsive force, even if he went to another world, he would probably be a little restrained.

Before solving this problem, Roy did not want to go to other worlds for now.

So while waiting for the completion of Frostfire City, Roy took out the Demon Bible steles to research when he had nothing to do. He vaguely felt that he needed to collect other steles and gather them together, but he had no clue because of the lack of intelligence.

This was also the most challenging place for young demon lords like Roy. Since they were not old enough, when they wanted to investigate some ancient matters, they often did not know where to start.

After all, demons rarely communicated with one another unless they were working together with a certain force. There was no internet and the like here, and there was only a one-to-one communication method like the projection pool. Moreover, the premise was to know the coordinates of the other party’s projection pool. It was not convenient to communicate, so it was naturally difficult for Roy to obtain information.

In the process of building the city, Roy was thinking about whether he should build a magic network or something like that… But after thinking about it, even if he built a magic network, it would probably only be used in his territory. It would be useless if he could not lay it in the territories of other demons.

Hmm, after the completion of the city, it seems I’ll need to send some people to explore the surrounding fragment worlds. Splendid isolationism is unacceptable. I have to establish contact with other demon lords.

Roy thought of Demon Lord Rogeros. He did not know which fragment world his territory was, but it would be great if he could find its location. At least, a demon lord like Rogeros had been pretty easy to talk to, so as long as he did not have any hostility, there was a possibility of communication. Of course, if you wanted to explore outside, you had to ensure that your own strength was formidable because when you discovered the other party, the other party would also discover you. If they sensed that you were weak, it was difficult to guarantee that the other party would not give birth to covetousness.

Therefore, the next step in Roy’s plan was to increase his power. If he used over sixteen million souls to transform them into his magic power, he should be able to improve tremendously. Hmm… It would probably take a lot of time to digest them all, so he would just take it step by step.

In addition, there were many things that he needed to attend to. Now that he had his territory, he was still considering whether to plant the Red Sea Egg.

The Red Sea Egg was a demon creation of Demon King Lilith. Ever since returning from the Darksiders world, Roy had placed the Red Sea Egg in the system space in the shape of a seed. But because he had not stayed in the high-rank demon level for long, he had not planted it. Now that he was a demon lord, he might stay in this fragment world in this level of the Abyss for a long time, so he could finally consider planting it.

However, Roy was a little worried about whether this demon creation had any connection to Lilith and whether she would sense it after it grew up from the seed. This thing seemed to be quite important to her, and it would be bad if she came to find him. That woman… or rather, that female demon was too mysterious. He could not see through her at all, so he had to find a way to avoid trouble that he could avoid.

Finally, it was the matter of the Dark Messiah, Sareth.

Julia, Benia, and Cassandra had asked Roy more than once, and they had no idea what he wanted to do by bringing Sareth back to the Abyss.

Cassandra was a lich, and she could appear in the Abyss because of the master-servant contract between her and Roy, but Roy did not establish a contract with Sareth. The reason why Sareth could stay in the Abyss was simple. He was a Child of Taboo!

This kind of half-human half-demon Child of Taboo could really freely travel between the Abyss and the human worlds. This time, Roy saw it for himself. He could not feel any world repulsive effect on him.

This baby was still breastfeeding, so of course, he could not withstand the extreme cold weather on the icy plain. Thus, Cassandra had been raising him in the warm area near the volcano. Roy had visited him once and found that the dark aura on Sareth was much richer. It seemed that after coming to the Abyss, the dark aura on him increased.

Although Roy had returned to the Abyss after Urgash appeared, he knew that the world of Ashan had probably perished this time. In other words, the Prophecy of the Dark Messiah would probably not be fulfilled by Sareth.

Sareth was Kha-Beleth’s child. Roy brought him back not because he wanted to raise Kha-Beleth’s son, but because he was really curious. If a demon-human hybrid like Sareth grew up in the Abyss in the company of demons, would he be more like a demon or more like a human?

Would he acknowledge his demon bloodline or his human bloodline?

Hmm, it could not be said that it was a human bloodline. Although Isabel was human when she gave birth to Sareth, she later became a seraph. Thus, strictly speaking, Sareth should be the child of a seraph and a demon lord!

In that case, Sareth should be considered a nephilim or nephalem!

F*ck, he is a proper main character template… Roy was not too concerned if Sareth was the main character template, but he had to say that Sareth was definitely a very precious experimental sample for him. Demon lords like Kha-Beleth were trying to create demon-human hybrids, and demon kings like Lilith were trying to create nephilim. Roy could finally observe with his own eyes how powerful a Child of Taboo was.

Now that he had become a demon lord, he naturally had to cultivate his own forces, so he planned to raise Sareth. If Sareth was really that powerful, then perhaps he could become a sharp sword in his hand.

Think about it. With Sareth’s ability to travel freely between the Abyss and the human worlds, if Roy wanted to go to other worlds in the future, he could send Sareth to be the vanguard. After he went to a human world, he could think of a way to summon him. As long as Roy solved the problem of the world repulsive effect, he could go to any world. Perhaps this was the ultimate reason why many demons created demon-human hybrids. They were thinking of the same thing as Roy… Of course, Roy was not stupid. In many novels, this kind of Child of Taboo had awakened his humanity because of love or various reasons, and he eventually turned around and killed the boss behind the scenes. There were many stories. Although these novels were from the standpoint of humans and catered to human mentality, and the situation would not necessarily become true, Roy still had to guard against it.

Roy needed to observe the psychological changes in Sareth at all times…

Time quickly passed by while he was busy. A year later, Roy’s Frostfire City gradually took shape…
