Fyveins

## Appearance

Their skin is dead white, even whiter than humans with the fairest complexion, and it feels soft to the touch, similar to human corpses that have been soaked in water and swelled. The water content is relatively high, making people feel that a piece of flesh can be peeled off with a pinch, but in fact On the contrary, it is very resilient. Therefore, some scholars speculate that their predecessors were aquatic humanoids, and may even be the aquatic subspecies of darohuman (this argument does not seem to withstand scrutiny).

Their eyes are different from those of humans. They seem to have no whites, and their outlines are similar to humans; their tongues are also similar to humans, but slightly longer and pointed; they have nose bridges and nostrils, but no pinnae, and ear canals are wider than humans.

Clear light blue veins cover their whole bodies. Humans who see them for the first time will always regard them as blue veins. When they have mood swings or perform similar spells, these veins will become clearer and even shimmer, but usually they are not so clear. Obviously, these patterns of veins also appear in most core vein civilizations, and it is speculated that it is a common body worship, just like human reproductive worship. The veins on the skin of each nuclear-veined person are different, which means that their magical abilities are also born different. There are rumors that there are subspecies of the Chosen that every inch of skin is covered with dense veins.

## Ingestion

Fyveins need to eat food with a very high core content, which are generally discarded or natural magic items. They grind these things into powder and eat them. Sometimes they also eat human food. Their taste is similar to that of humans. They usually excrete waste by vomiting.

## Physiology

The digestive tract of Fyveins is blind and connected to reproductive organs such as the uterus.

Fyveins have a very flexible lifespan, ranging from over fifty to several hundred years old, depending on the level of civilization.

The body of Fyveins is composed of six major systems: motor system, nervous system, respiratory system, digestive system, reproductive system and Kernel system. Their Kernel system undertakes the functions of circulation, excretion filtering and regulation. They don't have a heart, only a Kernel heart, which is the transit center for magic.

The blue veins on Fyveins normally glow faintly, but they can choose to control the intensity of this light. When they use magical powers or are emotionally excited, this blue light will be extremely dazzling, and the density of veins will increase, and their eyes will also emit blue light.

## Reproduction

They are single-sex creatures, which are defined as all-female by the academic community. When they reproduce, their bodies can split into reproductive worms. The genes of this worm are the male version of them, but their appearance is elongated palms The size of a white worm (Fyvein Maggot), which burrows into the mouth of another female and completes conception. Their childbirth is similar to that of humans, but because the birth canal is wider, the risk of childbirth death is smaller.

The sexual pleasure of Fyveins comes from receptors in the mouth.

Theoretically, they can self-breed, but the offspring produced are mostly diseased. Nuclei do not have estrus, so there is no collective baby boom.

## Society

Fyvein is the second most numerous race in the multiverse after humans, and their footprints are all over the bizarre worlds outside the shared plane group, so they are also "kindly" called "foreign magic locusts" by other races.

They are born able to manipulate the magical race without tools, but practice can make them better control this ability, 85% of the tribe can only use magic to do some simple things. Almost most of the core civilizations rely on spells and magic. Studying non-magic is considered deviant, but there are still rebellious young people who embark on this path.

Fyvein can identify people by the distribution of veins, which is similar to human fingerprints.

## Subspecies

Some Fyvein have hair that can disguise them as humans. Some Fyvein have more magical powers, and their veins are denser and more dazzling, and this subspecies is usually derived from mutation.

## Evolution

Fyvein's upper-level ancestors are still unknown, and some people speculate that they have a closer relationship with humans and Homo sapiens.
