The castlevania, built by the eruption of a volcano in Serren, does not seem to have a name.

Because for the demons, this is just an outpost for attacking Erathia, it is located in the border area, and as the battle line is extended, the replenishment of troops through this castlevania will become slower and slower, which means that in Serren's original plan, this city will eventually be abandoned.

It is precisely because of this that when Roy rushed back to this city, there were no more high-ranking demons stationed in it, and only some small demons remained in this city, and Ignadis did not take these little demons with him when he left, they were left as coolies and defensive forces, and from this point of view, it can be seen that the demons will abandon this place in the future.

Because he is also a demon, Roy entered Castlevania very smoothly, and some of the little demons who stayed here have seen Roy and know that he is Serren's lieutenant, although they don't know what he was going to do when he suddenly came back alone, but with the character of a demon, they will not ask more.

When Roy found that there were no more mid-rank and upper-rank demons in this city, he was even more relieved, and after entering the city, he went straight to the location of the summoning array.

During this period of time back, Roy found that the power of repulsion in the world seemed to have increased a little, and it seemed that this was the case, as time went by, the power of repulsion would continue to strengthen, and in order to resist this repulsive power, Roy's magic energy consumption was gradually increasing, and maybe in the end, after Roy's magic energy consumption could not withstand this power, he would eventually be expelled back.

More powerful demons may be able to stay in this world for a longer period of time, but no matter how long, they will still be expelled, so Serren Ignadis, these high-ranking demons, in order to stay in this world as much as possible, even did not hesitate to sign a demon contract with the people of this world to work for them, and this contract person is the King Lucifer Legan they have been talking about.

Who this person is, Roy doesn't know, and he can't see it, but it can make the superior demon loyal to him, it can be seen that he is not an idle person, maybe it may really be the incarnation of Lucifer.

It's just that because of Roy's plan, Selren was killed in advance and expelled back to the abyss world, which inevitably affected the demon army's plan to invade Erathia.

Coming to the summoning array, Roy carefully compared the pattern of the magic array with the one he had seen Serren draw before, and only after confirming that it was correct, Roy began to input magic power into the summoning array.

Generally speaking, the pattern style of the magic array, the text arrangement are fixed, with its specific function, once completed, there will be a special purpose, if there is a ready-made magic array, then you only need to input the magic power, in other words, it is easier to understand, such a magic array is like a household appliance, it can be used when it is energized!

The magic array engraved in the Castlevania City, its function is to open the door of the abyss, connect with the altar set in the abyss world, and teleport the demons on the opposite side, such teleportation is generally one-way, the same, when Roy wants to teleport back, the door to the abyss that will be opened at that time is also a one-way teleportation, so there is no need to worry about other demons running in and causing a crash.

Roy followed the direction of the mana output that Serren had done when he first watched Serren summon those high-level demons, and reversed it, first using magic to activate the pattern in the center of the magic circle, and then gradually spreading to the outer circle.

This is the so-called reverse output of magic power, Roy has little knowledge of magic arrays, and he doesn't know if this is the right thing to do, so he is just trying it now.

However, fortunately, he succeeded, and the magic array began to glow slightly, gradually activating.

In fact, it's not that Roy is lucky, in fact, the magic array that connects the abyss world in this way has gradually been fixed into a fixed pattern for thousands of years, after all, the demons sometimes need to teleport themselves back, so this kind of general magic array itself has both summoning and counter-summoning functions.

The black fog was filled, and the door of the abyss opened, just looking at the pitch-black mist, Roy couldn't help but think of the Dark Fruit, in a sense, when the power of the Dark Fruit was activated, it was quite similar to this black fog...... The Dark Fruit also has spatial ability, that is, the Dark Cave that can suck objects into, so does this mean that the Dark Fruit can also connect to another space like the Abyss Gate? ?

For this question, Roy just thought about it casually, and put it down for the time being, after the abyss gate opened, Roy did not enter rashly, but let the fat tiger go to catch a little demon first.

In front of these little devils, the fat tiger is super fierce, not to mention the little devil, even those genuine cerberus can't beat the fat tiger now, after getting Roy's order, the fat tiger immediately jumped over, pounced on a little devil passing by, and after throwing the little devil to the ground, he stretched out his mouth and bit the back of the little devil's neck, but it didn't use much force.

This little devil was bitten by the fat tiger, and it originally wanted to resist, but it suddenly didn't dare to move, and was carried back to the magic array by the fat tiger.

Roy also found an iron chain at this time, and he didn't talk nonsense, he directly twisted the little devil, tied it tightly with the iron chain, and then placed a camera tied to the iron chain.

This camera, of course, was made by Roy in the system, and the automatic camera function has been set up, and after arranging it, Roy grabbed the other end of the chain with one hand, and threw the little devil into the abyss gate with the other.

He needed someone to find out if the abyssal world was on the other side of the Abyssal Gate.

After throwing the imp out, Roy waited for a moment with the chain before pulling it back.

However, it's a pity that the one-way teleportation is really a one-way teleportation, even if the chain is tied to the body, the little devil can't be pulled back, and the chain still has a feeling before, but when Royla came back, the feeling from the chain suddenly became empty! By the time Roy pulled all the chains back, the little demon had mysteriously disappeared!

It's an inanimate object like a chain, and it's nothing, even the camera on it is still there.

Roy picked up the camera and looked at the photos that were automatically taken inside, and then breathed a sigh of relief, sure enough, the scenes captured in the photos were the scenes around those altars in the Abyss World.

In other words, there is nothing wrong with this abyss gate, as long as Roy enters and doesn't look back, the reason why the little devil disappeared is because he was lost in the chaotic space......

"Let's go Fat Tiger, go back!" Roy greeted the fat tiger, and then walked into the mist of the Abyss Gate in unison.

The light changed, and when he was cheerful, Roy found himself on top of an altar, and the fat tiger was at his feet.

It's just that I don't know where it is, or if it's a shallow abyss world, and I don't know how far it is from the altar where I was summoned in the first place.

There were no other demons around the altar, and after Roy and Fat Tiger left the altar, the magic circle that had lost its magic power gradually stopped, and the abyssal gate gradually closed.

With the fat tiger spreading its wings and flying, after moving away from the location of the altar, Roy soon got good news.

The good news is that this is indeed a shallow abyss world, because Roy has seen several lower demons appear nearby, with the strict class theory of the demons, it is impossible for the lower demons to live in the deeper abyss without the need for promotion, however, a little troublesome, Roy did not find his familiar scenery in this vicinity, he seems to have been randomly teleported to a strange place.

The abyss world is really too big, it can accommodate tens of millions or even hundreds of millions of demons, so you can imagine how much space there will be?

So Roy didn't dwell too much on this point, he began to take the fat tiger and look for a way to the lower abyss.

This is easy to understand because lava rivers fall deep into the center of the earth with gravity, and the deeper you go, the deeper you go, the deeper the abyss.

Roy must be promoted now, firstly, because the lower demon is indeed too restrictive, and secondly, because his demonic energy has reached a bottleneck, and now he doesn't dare to use the essence magic potion, for fear that he will explode and die.

So, in the following time, Roy took the fat tiger and began to look for the entrance to the lower abyss.

But it's actually quite hard to find, because sometimes you follow a lava river for hundreds or even thousands of kilometers and you don't necessarily find the end, not to mention that each of these lava rivers doesn't necessarily lead to the lower worlds.

After more than a month of tossing and turning, the hard work paid off, and after Roy flew hundreds of kilometers with a magma river, he suddenly saw a huge crack in front of the river!

The breach, about five kilometers long, seems to have been formed after the earthquake shook the ground, and the magma river was cut off here, where the fiery red lava fell down the breach, forming a lava waterfall.

When Roy flew above and looked down at the rift from above, he found that the rift was bottomless, and all the way down, he could only see a fiery red point of light, which was the light brought by the magma.

"This should be it, right?" Thinking so, Roy slowly flew down from the rift with the fat tiger.

One kilometer, two kilometers...... I don't know how long it flew, or how deep it fell vertically, before Roy gradually noticed that the rift was beginning to narrow.

When Roy finally flew out of a hole tens of meters wide, suddenly, an equally vast and wide space appeared in his field of vision.

Compared with the shallow abyss world, the space here seems even darker, this is because there is no shallow abyss-like moss on the cave wall here, and as soon as he enters here, with Roy's eyesight, he can't see far at all.

Demons have dark vision, and it seems that they have evolved to cope with this dark environment......

While adapting to the dark environment, Roy also felt that his wings had a very tired feeling, not that he had been flying for too long, in fact, the distance of this vertical fall, which was about ten or twenty kilometers, was not too deep, and Roy's wings would feel tired, that was because the gravity here seemed to be stronger than the shallow abyss world!

Under this gravity, Roy's body became heavy, and every flap of his wings required more effort, how could he not be tired?

"This is the middle abyss, right? Well...... That's what you might call it, right? Roy thought to himself.
