Roy summoned hundreds of low-level demons from the upper abyss world in the form of soul hiring, handed them over to Bainia to lead, and began to build a new castlevania.

In fact, with the Lumens Flame, Roy could directly shape the Castlevania by himself, but he didn't do it, but handed it over to the demons to build, because only the demons could build a demon building with a pure style.

In the frozen land, digging earth and rocks is very wasteful, but this time the demon worm has made a contribution, and it has a strong digging ability, holding the soft soil in the ground and bringing it up, so that the demons have building materials.

In Roy's plan, the new castlevania will be about five square kilometers in size, and unlike the separate castle that the demon occupied when he first ascended to the throne, this time it will be a real small city, covering the underground volcano and the surrounding area, and in the outermost part, Roy will use his frost magic to build a tall ice wall as a wall, and will also drain the lava from the volcano as a moat.

It would be a spectacle, a spectacle of ice and lava at the same time, and such an environment would not be seen even in the entire Abyss World.

And this new castlevania was also named [City of Frost and Fire] by Roy......

The construction of such a large area of the city naturally cannot be completed overnight, and the construction period will last at least more than a year, but Roy has time now, so he is not in a hurry to take his time.

In the short term, Roy doesn't plan to go to other worlds, firstly, he got quite a lot of souls in the Yashan World this time, more than 16 million, so many souls, enough for him to consume for a long time, and secondly, even if he wants to go to other worlds now, he can't go for the time being, as a demon lord, he now wants to fight against the power of world rejection It takes a lot of money, if there is no effective way to fight against the effect of rejection, even if he goes to other worlds, it is estimated that he will be a little constrained.

Until this is resolved, Roy doesn't really want to go to other worlds for the time being.

So while waiting for the completion of the construction of Frostfire City, when Roy was idle, he took out the stone tablet of the Demon Bible for research, and now he vaguely felt that he needed to collect other stone tablets to make it together, but he had no clue because of lack of information.

This is also the most difficult place for a new, young demon lord like Roy, if he is not old enough, when he wants to explore some older things, he is often denied entry.

After all, between demons and demons, unless they work together with a certain force, otherwise, there is very little communication between each other, there is no Internet or anything like that, only a one-to-one contact method such as a projection pool, and the premise is to know the coordinates of the other party's projection pool, such an inconvenient communication, naturally makes it difficult for Roy to obtain information.

So much so that in the process of building the city, Roy was thinking about whether to build a magic net or something...... But then I thought about it, even if I built a magic net, it was estimated that it could only be used in my own territory, and it would be useless if it couldn't be laid in the territory of other demons.

Well, after the construction of the city is completed, it seems that it is necessary to eliminate the manpower to explore the surrounding fragmented world, and glorious isolationism is unacceptable, and it is necessary to establish contact with other demon lords.

Roy thought of the original demon lord Lojelos, and he didn't know which fragment world his territory was in, if only he could find its location, at least Lojelos, the demon lord, was still good at talking, as long as he was not hostile, there was the possibility of exchanging information.

Of course, if you want to explore outward, you must ensure the strength of your own force, because when you find the other party, the other party will also find you, if you perceive that your strength is weak, it is difficult to ensure that the other party will not covet it.

So next, improving one's own power is also in Roy's next step, more than 16 million souls, if used to transform into their own magic power, should be able to greatly improve, huh...... It is estimated that if you want to digest it all, it will take a lot of time, just step by step.

In addition, there are a lot of things that Roy needs to deal with, and now that he has a territory, Roy is also considering whether to plant the eggs of the Red Sea.

The Red Sea Egg, this is the demon creation of the demon king Lilith, since the return of the Dark Blood World, this Red Sea Egg has been placed in Roy's system space in the form of a seed, but because Roy did not stay in the upper demon world for a long time, he did not plant it again, and now after becoming a demon lord, he may stay in the abyss of the fragmented world for a long time, so he can finally consider planting it.

It's just that Roy is a little worried about whether this demonic creation will have anything to do with Lilith, whether it will be perceived by Lilith after it grows up, etc., this thing seems to be very important to Lilith, in case Lilith comes to the door, it will be bad, that woman...... Or maybe that the female demon was too mysterious for Roy to see through at all, so the trouble that could be avoided had to be avoided in a way.

Finally, there's the dark messiah Silas.

Juliel, Bainia, and Kassandra had asked Roy more than once, and they had never been sure what Roy was trying to do by bringing Silas back to the Abyss.

Kassandra is a lich, she was able to appear in the abyssal world because of the master-servant contract between her and Roy, but Roy did not make any contract with Silas, and the reason why Silas was able to stay in the abyss world is simple, he is a forbidden child!

This kind of forbidden son who is half human and half demon, that is really able to travel freely between the abyss world and the human world, this time Roy can be regarded as having seen it, in him, Roy does not feel any world rejection effect.

This baby who is still breastfeeding, of course, can't bear the extremely cold climate on the ice field, so this time has been brought by Kassandra and raised in the warm area near the volcano, Roy went to see him once before, and found that the dark aura on Silas was much stronger, it seemed that it was because after coming to the abyss world, the dark aura on his body increased.

Although Roy came back from the Asan world, after the appearance of Ogas, Roy knew that the Asan world was estimated to be finished this time, that is to say, the prophecy of the dark Messiah at the beginning was estimated to be unfulfilled in Silas.

Silas is Cabellus' child, Roy brought it back, not to raise a son for Cabeles, but he is really a little curious, if a half-demon like Silas is in the abyss world, growing up in the company of demons, then will he be more like demons or more like people at that time?

Will he identify with his demonic bloodline, or will he identify with his human bloodline?

Well, it can't be said that it is of human blood, Isabel that woman, although she was a human when she gave birth to Silas, but later became a Seraph, so strictly speaking, Silas should be the child of a Seraphic Angel and a Demon Lord!

In that case, Silas should be considered a Philistin, or Nephilim!

Great,Proper protagonist template......

Whether it's the protagonist template or not, Roy doesn't care too much, but I have to say that Silas is definitely a very precious experimental sample for Roy, demon lords like Cabellus are trying to create half-demons, and demon kings like Lilith are also trying to create Nephilim, where is the strength of this kind of forbidden child, Roy was finally able to observe it with his own eyes this time.

Roy is now a demon lord, so he naturally wants to cultivate his own power, so he plans to raise Silas to see if Silas is really that powerful, then maybe he can become a sword in his hand.

Think about it, with Silas's ability to travel freely between the abyss world and the human world, if Roy wants to go to other worlds in the future, he can first send Silas as a pioneer, let him go to the human world, and then find a way to summon himself, as long as the problem of the world exclusion effect is solved, Roy can go to any world he wants.

Perhaps, this is also the ultimate reason why many demons created half-demons, and they wanted to go with Roy......

Of course, Roy is not stupid, among many, this kind of forbidden son awakens human nature because of love or various reasons, and finally turns around, and the story of the behind-the-scenes boss who kills him with water, that's a lot, although this kind of plot processing is from the standpoint of human beings, in order to cater to human psychology, the real situation is not necessarily the case, but Roy has to guard against it.

This requires Roy to keep an eye on Silas' mental changes......

Time flew by in a hurry, and a year later, Roy's City of Frost and Fire gradually took shape......
