The purple-red water of the pool bubbles from time to time, and the steam fills the air, as if it is boiling.

At this time, there were already dozens of lower-level demons soaking in this pool, and from time to time, there were lower-level demons like Roy who needed to be promoted were rushing here, Roy had only observed for a short while, and he had already seen several lower-level demons pass through the entrance and enter the pool.

The mid-rank demons who had been hovering around the periphery didn't stop them from entering, and judging from the fact that they were bounced off after touching the barrier, it seemed that they wanted to go in again.

Roy took the fat tiger and slowly flew towards the place of refining, and in the process, Roy witnessed the promotion of some of the lower demons.

After soaking in the pool for a period of time, the bodies of some of the lower demons have changed more or less, some of the demon horns on their heads have changed, becoming thicker and more twisted, and even from the original may have been relatively straight, gradually bent and coiled into a circle, just like the difference between goat horns and sheep horns, while some have changed their body shape, the original body has expanded or shrunk, and some have simply undergone a big change, there may be a few more pairs of eyes on the face, and a few more arms, Or the one that originally had no tail also grew a tail.

Roy even saw a smaller demon in the pool, with its chest gradually bulging and a pair of wings growing out of its back, and it turned from a demon of unknown breed to a succubus that Roy was familiar with!

I don't know if this demon was originally male or female, if it was originally a female, it would be easy to say, but if it was originally a male, then this change would be a big change! This is no longer something that can be described by a women's clothing boss......

This scene made Roy think, this place of refinement felt as if it was awakening the demon's bloodline!

Roy is sure that the demon that turned into a succubus, the demon blood in his body definitely contains the blood of a succubus, and the power contained in this pool will bring out this bloodline, and then this guy will transform into a succubus.

At this time, Roy also landed, and under the gaze of the middle demon in the outer circle, he walked into the place of tempering, but after he came here, he did not rush into the pool, but chose to continue to observe.

He still remembered that he had this orthodox demon wing on his back, and he had always been regarded by other demons as the bloodline of the superior demon, and the spider queen Alania who he met at the beginning said so, and later Serren also said the same, but Roy never figured out what races the so-called superior demons had.

It stands to reason that if you judge by wings, then the demon race of succubi, which is a succubus, should also belong to the upper demons, but the succubi that Roy encountered in the Invincible World of Heroes, those who were summoned by Serren, are all mid-level demons, but if you don't judge it by wings, a demon without wings like Serren is a high-level demon.

So now, Roy is a little confused, the difference between the lower demon and the middle demon is easy to understand, it is nothing more than whether the bloodline has been refined, but what about the difference between the middle demon and the upper demon? It can't be a second tempering, right?

Actually, about this, Roy was wrong.

The so-called succubus, fire demon, abyss demon, etc., is just a simple name, in fact, such a title does not represent the type of demon!

This kind of name is just derived from the characteristics of demon power, for example, the succubus is a demon who is good at using charm methods, and the fire demon is a demon who is good at using fire, these demons, either strange or powerful, when they haunt the world, they are deeply feared by people, which leaves a deep impression, so in order to distinguish them from other demons, they are given special names.

However, such a title does not fully represent the race of the demon, not that every succubus is the appearance of that kind of demon girl, nor is it that every fire demon must be covered with flames.

Due to the bloodthirsty and warlike nature of demons, they rarely communicate with other races, so the races in the outside world have always been very confused about the demon race, even if there are some mages or scholars who specialize in demon science, trying to summon and enslave demons, trying to understand the situation of the abyss world from the demon's mouth, in the end, they only know only half-understood, because the demon's own bloodline is chaotic, and even they themselves are sometimes difficult to distinguish clearly, how can they explain it to others?

The social form of demons is very complicated, although there are demon languages and demon writing, but these are just demons are only obtained from memory inheritance, in the demon society, there is no school, education system, after all, with their nature, it is impossible to form any form of order.

Of course, having said so much, it's not that there is really no way to distinguish between demons, in fact, compared to the lower and middle demons, after reaching the level of the upper demon, with the continuous improvement of demon intelligence, there is still a more general way to distinguish between the ruling class of demons.

And this division is relatively simple, in general, there are four types of demons: war demons, elemental demons, trickery demons and chaos demons.

War demons, mainly refers to the physical combat as the main way of fighting demons, this kind of demons, usually for their strength, large size, good at using cold weapons are known, their demon heart of the magic power, often not in the form of magic, but attached to weapons, fists, claws, bring powerful attack effects.

And the elemental demon, as the name suggests, refers to the demon who is good at using elemental magic, in terms of the environment of the abyss world, the largest number of elemental demons are the use of fire elements, but there are also demons who can use other elemental magic, such as darkness, air, earth, etc., but these elemental magic, and the magic used by humans or other races are different, because some spells are pronounced in demonic language, similar to dragon magic, so it is also commonly called demonic magic.

In the case of trickery demons, succubi can actually be classified into this category, which refers to demons who are good at using various illusions, puppets, and other spiritual magic.

As for the final Chaos Demon, it is that none of the first three categories can be clearly divided, so it falls into this category, such as a certain demon, he can use fire magic, and is good at hand-to-hand combat, and maybe knows a little bit of confusing illusion or something, then this kind of demon who can do everything is a Chaos Demon.

These four types, which include almost all demons, are not distinguished by pure races, so it can be said that they are still a relatively standard way of discrimination.

As for the division of the upper and lower ranks, in fact, after the promotion process of refining the bloodline, the back is basically judged by the strength of the strength, any median demon who has completed the tempering is likely to become a high-ranking demon, as long as he can survive long enough and accumulate enough magic power, however, the process of refining the bloodline is a more important part, if the bloodline is tempered relatively pure, then the probability of becoming a high-ranking demon is naturally much greater.

Therefore, when Serren originally said that Roy had the bloodline of a high-ranking demon, he actually meant that Roy's demonic bloodline was relatively pure and had good potential!
