The maid squad is too strong, what use is there for me, the Demon King?

The aura of the vanguard of grey-robed men was indeed that of cultists from the Demon Order, but what stunned Delta was the grey-robed men who entered later.

She sensed a familiar aura emanating from them, but she couldn't quite place what it was, so she continued to stare at the newly appeared gray-robed figures.

When the servants behind her saw Delta suddenly freeze and not move, they assumed she wanted to enter later since they had not received any orders to change the command. They entered the battle without slowing down and clashed with the gray-robed men.

Delta only realized what was happening when the gray-robed men who came to her aid released the slightly blood-red bats.

So, we're from the same clan...

Strangely, Delta sensed a familiar aura from her own kind, yet couldn't recall what that aura was.

This is related to the habits of the vampire species.

Just as the saying goes, "Two tigers cannot share one mountain, unless one is male and the other female," pureblood vampires are quite scattered, and there can be at most two vampires of different genders in the same area.

Generally speaking, pure-blooded vampires have a very strong sense of territory and basically never interact with each other until death. Considering the long lifespan of vampires, this degree of "never interacting with each other until death" is much stronger than that of humans.

Of course, this only applies to pure-blooded vampires. In the same area, there can be many non-pure-blooded vampires, and they are all subordinates of pure-blooded vampires.

In the minds of vampires, pureblood vampires are the nobles among vampires, an incomparably prestigious existence.

So, where do non-pure-blooded or mixed-blood vampires come from?

This involves the two different reproductive methods of vampires.

One method is sexual reproduction, which is no different from other organisms. Pure-blooded vampires reproduce through sexual intercourse, producing pure-blooded vampires. Pure-blooded vampires reproduce with other species, producing hybrid vampires.

However, this situation is very rare.

In the eyes of vampires, all other creatures are food, and you will become aroused by food... Do you remember how many slices of bread you have eaten?

The majority of these rare cases involve pure-blooded vampires having children with humans.

Delta used to wonder why it was possible to have offspring with "food," but now she understands...

According to the general rule that "the longer the lifespan, the weaker the reproductive capacity," it is extremely difficult for pure-blooded vampires to have offspring, while it is much easier for them to pass on their offspring to other short-lived species (such as humans).

What, you're asking why there's no reproductive isolation between different species?

Yes, why exactly?

The second type of asexual reproduction, which is the assimilation of other creatures into vampires, is the main method of vampire reproduction.

The success rate of assimilation is not very high, and vampires rarely give up eating in order to assimilate their victims, but it is still much more frequent than sexual reproduction.

Vampires are an arrogant race, completely unaware that humans and demons are the protagonists in this world, and believing themselves to be at the top of the food chain.

Their pride wouldn't allow them to have sexual relations with other inferior creatures, and they rarely assimilate food. So where did these hybrid vampires come from?

Perhaps one day a pureblood vampire made a mistake, or perhaps a doujinshi plot emerged between a human and a vampire that is impossible to investigate.

In short, that's how the hybrid vampire was born.

Most of the grey-robed people are half-vampires, but there are also pure-blooded nobles.

Did they join the demon cult?

Delta, the blonde vampire, was only slightly surprised by this, but she had no intention of showing any mercy just because they were of the same race.

Vampires are not a united race; they are more often rivals to one another.

All she had to do now was kill all the grey-robed men who were attacking the caravan, nothing more.

With a crimson scythe in her hand, the blonde vampire Delta quickly joined the battle, slaying several gray-robed figures.

Blood magic is a special kind of magic that only vampires can master.

Having become a member of the Demon King's kin and already a rank eight professional, she is undoubtedly the strongest vampire in the world, and dealing with her fellow vampires requires very little effort.

Delta's appearance startled the grey-robed vampires. Even through the robes, they could sense Delta's aura and the blood scythe she wielded, and they could tell that she was a female pureblood vampire.

In an instant, the atmosphere in the arena changed.

The gray-robed vampire who was confronting the waiters suddenly retreated, leaving the waiters bewildered. They had no choice but to ignore the vampires and move on to the vanguard of cultists.

The cultists were also confused, not knowing why the vampires suddenly stopped their actions.

Delta felt this most acutely; all the vampires stopped moving and stared intently at Delta with burning eyes.

Delta, the blonde, mature vampire, frowned slightly.

What is that? It's disgusting...

The intense gaze made Delta feel nauseous, and she immediately decided to increase her magic output to quickly eliminate her "kin" in order to prevent herself from continuing to feel nauseous.

At this moment, a man stepped out from among the group of gray-robed vampires. He lifted the hood of his gray robe, revealing a handsome face, though his skin was unhealthy and sickly pale. He smiled, revealing the sharp fangs that were a characteristic of vampires.

"Beautiful lady, may I speak with you in private?"

Delta recognized this vampire, Vladimir Dracula, who was quite famous among pureblood vampires. They might have met briefly a few hundred years ago, but they weren't close.

Lend me a step to speak?

Delta knew she had nothing to talk about with him, and coldly brandished the blood scythe in her hand.

Vladimir's pupils contracted sharply. He was a sixth-order vampire, and he could not avoid the sudden attack from Delta, who was two orders higher than him. He could only use blood magic to try to neutralize some of the power.

As a result, Vladimir managed to block the attack and avoid being killed on the spot.

However, don't misunderstand, Vladimir didn't single-handedly withstand the attack from the second-highest level professional.

The moment the blonde female vampire launched her attack, one of the gray-robed vampires reacted and stepped forward to help Vladimir block the crimson scythe.

Delta was not annoyed at all when his first attack failed.

The other vampire is at the seventh level of magic power, which is already at the top level among pure-blooded vampires.

Pureblood vampires and elves share a similar problem: their lower limit is very high, but their upper limit is extremely low.

Faced with Delta's relentless attacks wielding his blood scythe, the two vampires were struggling to keep up...
