This story happened a long time ago, a long time ago. At that time, the orbit of the planet we lived on was not what it is now. Of course, it was not in its current position.
In today's terms, at that time, the earth was the only satellite of the sun, and it only rotated around the sun, with the north inward and the south outward, day after day, and the cycle remained unchanged.
Therefore, the entire Northern Hemisphere is exposed to the sun all year round without night, while the Southern Hemisphere is on the contrary, without sunlight all year round.
Therefore, two races slowly evolved on this planet: short-lived species and long-lived species.
The short-lived species living in the northern hemisphere, that is, humans like us, enjoy warmth and light, but their life span is very short. And the immortal species living in the southern hemisphere, the undead race that lives in coldness and darkness all day long.
Immortal species include many types, such as monsters, demons, ghosts, elves, vampires, etc., Which are collectively called immortal species.
Immortals are very powerful. They have special abilities that humans do not have. Compared with them, humans are as fragile as ants. But there is only one thing. Immortals are afraid of the sun, so no matter how ferocious and terrifying they are, they are nothing to be afraid of.
At that time, short-lived species and long-lived species coexisted.
However, coexistence does not mean that they can coexist.
