When the magic circle was poured, Serren appeared in the crater.

He stood on the edge of the magic array, his hands began to glow, and his mouth began to chant something in a low voice, and after a while, the magic circle began to shimmer as well.

Then, Serren jerked up his demon hoof and stomped on the ground, and with a loud bang, the entire volcano began to tremble.

It was as if there had been a great earthquake, and the entire mountain was shaking, and many demons standing upright were shaken and fell to the ground.

The magic array that Serren had poured out was actually an amplifier, and he borrowed the effect of this amplifier to use a magic that shook the earth and shook the mountains, so that the power of magic penetrated through the bottom of the volcano.

"Get out of here!" After Serren gave the order, the demons gathered on the volcano immediately rushed down lifelessly, even if they lived in a world with volcanoes and magma, it did not mean that the demons were not afraid of volcanic eruptions, on the contrary, the demons were the most afraid of volcanic eruptions, because they knew best what kind of destructive power volcanoes possessed when they erupted.

There were about two hundred demons summoned by Serren in advance, and not long after these demons fled, the volcano, which had been affected by the force of the earthquake, finally reached a critical point, let out a deafening roar, and began to erupt.

Billowing smoke with a large amount of volcanic ash, from the crater to the sky, by the force of the volcanic eruption, spewing out countless large and small still burning stones, these stones scattered in all directions, like the goddess scattered flowers, very beautiful, also very terrifying, with the eruption, the hot lava also flowed out of the crater, these fiery red rivers, along the volcanic mountain all the way down, burned all the trees and jungles along the way, some small animals did not have time to escape, but also buried in this magma flow.

It took two hours for the eruption to subside, but within a radius of ten miles around the volcano, it had all turned into scorched earth, and some of the diffuse magma had begun to cool and turned into black ground, while some of it was still hot, emitting a dark red glow and rising green smoke.

Selren looked at his masterpiece triumphantly and laughed wildly, he was so satisfied with this scorched earth territory that he could start building a city.

Yes, the purpose of detonating the volcano is to create an environment suitable for the demons to live, and the green mountains and green waters are not the style of the demons at all, and the demons love this kind of place full of sulfur-smelling air.

Under Serren's reprimand, more than 200 low-level demons, including Roy, began to work, they found large rocks, and while the magma ground was still soft, they polished the ground as much as possible to use it as a foundation, and when the foundation was laid, they began to build the city.

Roy didn't do anything at this time, he took the fat tiger and became the overseer of these demons, holding the city building blueprints and leather whips given to him by Serren, urging those low-level demons to build according to the plan.

In fact, the demons have never been engaged in construction, so Roy's task of overseeing is not light, he must always instruct the low-level demons who are working, otherwise they can build the wall like instant noodles, ups and downs.

Moreover, the demons still lack tools, all the buildings they build are just piled with stones and wood, such buildings, nine times out of ten are not reliable and will collapse, but the demons also have a way, because of the proximity to the volcano, they divided their hands to get magma at the bottom of the volcano, and after a little cooling, poured liquid rock on top of the fortified buildings, used to fill the gaps and strengthen the city walls.

Once the city was taking shape, Serren brought in new blueprints and told the demons to start building their own places to live.

To put it bluntly, it is a lair, each type of demon has its own type of nest that they like to live in, so after it is created, the demons will spontaneously classify and live in it, and Serren in these nests, respectively, carved a summoning magic array again, and then kept summoning the same kind of demons to this world.

For example, the demon kennel used to summon Cerberus hounds, in the demon kennel, Serren will only summon Cerberus out, and every time he summons a batch, he signs a contract with these cerberus and then lets them live in the kennel.

During this time, Roy has been secretly observing Seren's movements, and he found that the demons summoned by Serren are almost all of several fixed types, which may be due to the need to form an army and the need for the same troops, so he did not summon too chaotic demons, and Serren was able to summon these demons accurately almost every time.

Roy observed for a long time before he understood, it turned out that there was a trick in this, Serren seemed to know very well what kind of demons like a certain kind of things, for example, when he summoned the little demons, he would often add some powder made of bird or insect egg shells to the blood of the sacrifice, so that the breath of blood would change a little.

Every time he used this kind of sacrifice, he was able to summon a large number of little demons, these little demons, naturally, were those who had just been born not long ago, had just entered the shallow abyss world, perhaps the smell of egg shell powder in the blood, reminded them of the scene of eating their own demon egg shells when they hatched, in short, these little demons would always rush to teleport over.

And once they are summoned, their end is doomed, how much combat power can these little demons who have just been born for a long time have? Serren summoned them to increase the number of coolies and cannon fodder needed for future battles.

In addition to summoning the little devil, there is also a way to summon Cerberus, that is, mixing the blood with the urine of the griffon, Serren caught some wild griffins and raised them, when he mixed the urine of the griffon beast into the blood, the allure of the Cerberus is absolutely first-class!

This situation reminded Roy of the scene when he learned to fish in his previous life, using different flavors of bait for different fish......

When Roy was answering the call to pass through the Abyss Gate, he smelled the smell of blood mixed with the urine of the griffin beast, and he was wondering why the smell of blood was a little strange, where would he have thought that Selren was actually just seducing Cerberus at that time, and Roy didn't understand this kind of doorway at all, so he strayed into the ...... The Demon Summoning Ritual is like this, because you can't see what the situation of the summoner on the other side of the Abyss Gate is, so you can't avoid the risk at all, and once you encounter this kind of trap summoning, you can only rely on your own strength to get out of trouble.

Only demons know demons best, Selren, the upper demon, doesn't know how long he has lived, when he feels what kind of demon he needs, he has a way to summon what kind of demon, the abyss world is very big, so big that no one can tell how many demons live in it, even if the bloodline of the lower demon is chaotic and the appearance is strange, but among so many demons, there are still a lot of demons of the same kind.

And without exception, all the demons summoned by him were enslaved by him, in order to deal with the next war, it is impossible for Serren to let the summoned demons go back easily, here Serren is a demon lord, and the summoned demons are his people, after the way home was blocked by Serren, the demons can only let him take what he wants.

Of course, there are also those who, like Roy, did not cooperate and resisted after being summoned, but they were all honest after being smoked, and after the contract was made, they obediently worked for Serren.

Roy looked at this scene, just watched coldly, but did not have any sympathy, in fact, he knew very well that this kind of approach of Serren was the most in line with the demon's behavior.

Between demons and demons, there will never be any warmth, except for killing, that is, exploiting, often rarely produce the concept of the same kind, even if high-level demons will pay more attention to blood, it is only for demons of the same level, like this high-level demons treat low-level demons, enslavement and beating are just basic operations, it is not surprising at all, Serren summons demons to fight for him, the cost is almost equal to nothing, but the benefits are a large number of souls, such a high return ratio, let alone demons, The capitalists of mankind will flock to it.

As time passed, the castlevania had gradually grown in size, and at this time, two more high-ranking demons appeared and came to join Serren......

These two high-ranking demons came with a small army of demons and rode nightmare warhorses, which were short-tempered, with shiny black hardened skin, a horn-like demon horn on their heads, and four hooves burning with raging flames, leaving a trail of flames wherever they went.

This Nightmare Warhorse also belongs to the Demon, not the Monster, because they are sapient and are a kind of mid-rank demon, and many non-high-ranking demons like to enslave this Nightmare Warhorse to act as a mount.

The two high-ranking demons were wearing cloaks and couldn't see clearly, and after entering Castlevania, they began to talk in the interior hall with Serren, and Roy, an elite demon, has been used by Serren as a deputy because of his high intelligence during this time, so when the three high-ranking demons talked, Roy stood guard outside the gate and easily heard their conversation......
