In this world where humans and demons coexist, due to people's greed, humans and demons are incompatible with each other. Demon elixirs can not only extend people's lifespan, but also keep them young forever, while human blood elixirs can greatly increase demon skills and ascend to immortality. For thousands of years, humans have killed demons, and demons have killed humans, only to end up with both sides losing. Even if humans and demons fall in love, it will always be miserable, until the appearance of these two people changed the situation.
Intention: True love comes from deep within the soul
