Nightmares are a very special race. This race is often confused by humans with succubi and dream demons. However, unlike the succubi, which only has women, and the dream demons, which can only appear in dreams and have no entities, the nightmare is actually a physical race with gender.

Unlike succubi, a race that can bond with males of almost all other races and give birth to a girl, it is definitely a succubus. Nightmares are actually very difficult to combine with other races to produce offspring, and even combining with nightmares of the same race to produce offspring is a more difficult thing. Therefore, whether it is in the demon world or on the continent, the number of nightmares is not as many as humans think, and most of the so-called nightmare attacks are actually just succubi as female nightmares. What's more interesting is that nightmares don't have a direct relationship with the target of the attack, they often only need the spirit to enter the prey's dream, and they can make the prey be sucked into the essence through the illusion in the dream. That's why the Dream Demon is sometimes mistaken for a nightmare relationship. It's just that the dream demon absorbs spiritual power, which will cause the prey's mental power to overdraw and die, while the nightmare absorbs life force and essence, and usually, it will only make the prey feel very tired. Therefore, although Nightmare has a bad reputation on the mainland, the actual situation is that it bears the black pot for the succubus and the dream demon.

As mentioned earlier, Nightmares are not unisexual, so there are actually male and female Nightmares. However, the Nightmare Clan has a very peculiar trait, that is, the offspring of their clan, the juvenile Nightmares, are born genderless. Only after a young nightmare learns how to distinguish between men and women will he or she identify the next gender as a temporary gender. That's right, it's a temporary gender, and before adulthood, juvenile nightmares can change their gender at will by their own will. Usually, young nightmares will choose a temporary gender based on their proximity to one of their parents, and will not confirm their gender until they become adults and know how to choose their partner. Of course, the persistence of gender throughout the year can lead to the solidification of some habits, and the gender will not change in adulthood. Only the juvenile nightmares who are very playful and know how to take advantage of their own trait will constantly change their gender.

Nightmares' ability to change gender actually comes from their ability to control and weave dreams. It's just that juvenile nightmares don't need to absorb the essence of their prey, and they don't need to weave dreams, this ability is transformed into the ability to change their own gender, and at the same time, when changing their gender, the transformation of appearance and physical characteristics is also one of the ways for juvenile nightmares to master this ability, after all, the real transformation can make juvenile nightmares actually experience the ways and details of change. In adulthood, the more gender-changing nightmares in childhood, the stronger the ability to weave dreams, and the more realistic the dreams they make.

It is more difficult for ordinary nightmares to produce offspring with other races or the same race, but there is a nightmare that is very easy to obtain offspring, which is the primordial nightmare. To be exact, this nightmare can easily obtain a descendant. Primordial Nightmare is a term for a nightmare with a very pure bloodline, or a true nightmare. Primordial Nightmares can combine with any gender of any humanoid race by their own volition, and give birth to a descendant with Nightmare blood, and can even choose the race and gender of this offspring. As a result, most of the original primordial nightmares chose their own nightmare race for their descendants. However, these nightmares are mixed with the bloodlines of other races, although they have improved the shortcomings of the original nightmares, which are weak in constitution, not strong in magic, and even have a short lifespan. But it has lost this ability to absolutely give birth to the offspring of nightmares. Only a small number of primordial nightmares who insisted on bonding with their own clan continued the ability of primordial nightmares. It is important to note that each Primordial Nightmare cannot use this ability to obtain new offspring until the death of the offspring it designates, or even through other means. And the half-breed nightmare without this ability is not guaranteed to have offspring, but there is no limit to the number of offspring, there have been nightmares who have sacrificed their lives for the continuation of the race to combine with humans and goblins who are more fertile than humans, setting an astonishing record of a total of fifteen nightmare offspring and more than seventy half-blood offspring - I have to sigh that almost all of the nightmare offspring are born of human women. If it weren't for the fact that the nightmare offspring born of humans have weaker dream abilities than the goblin offspring, I am afraid that humans would be considered the most suitable mother for breeding nightmares. Even so, there are still some Nightmare people who are eager to have offspring who will try to combine with humans to have offspring.

However, due to the existence of primordial nightmares to ensure the continuation of the race, the pure-blooded primordial nightmares are still maintained, and almost every one of them is a treasure of the nightmare clan. If it weren't for the accident, no community of Nightmares would have allowed the Primordial Nightmare to combine with other races to have children. Not to mention, that kid wasn't a nightmare yet, just an ordinary half-blood.

"Therefore, we deduce that Miss Zilde's mother may have been an accidental exile of the primordial nightmare, most likely orphaned like Miss Zilde, and adopted by that demon village. And then through the union of nature, or perhaps it was her mother's desire to have a demon child that led to the appearance of Miss Zilde. After giving a detailed explanation to Shi Leiyin, Liya gave such a conclusion.

"At the same time, I know through the records of the Chamber of Commerce that Miss Zilde had a demon stepmother before, and at that time, she showed male sexual characteristics. This time it will change to female sexual characteristics, most likely because of you," Liya pushed her glasses and pointed at Shi Leiyin.

"Me?" Shi Leiyin felt a little inexplicable.

"That's right, you. Leah paused and added, "It's because of your different attitudes towards boys and girls, to be exact. Before I met you, I knew about your existence as a protector through Miss Shui Jing. From their attitudes, we can know that although you treat the three of them equally, you are more doting on Miss Shui Jing. This may be one of the reasons, Miss Zilde is still just a child after all. And after separating from your adoptive mother, who has been raising you, you are the only one you can rely on to be close. So when I see that Miss Shui Jing, who is a girl, can get more of your doting, it's normal to want to transform into a woman. However, Miss Zilde doesn't know that she has Nightmare blood, and her biological mother didn't give her birth as a Nightmare race, so although she has the idea of becoming a woman, she has not yet had the ability to touch the Nightmare bloodline. It wasn't until Sister Izumi used that thing for the three young ladies," Liya smiled wryly, and said that it was only now that she really needed to explain.
