An ordinary female college student saved a vampire because of her temporary kindness, but unfortunately she was transformed into a vampire and became the sole heir of this vampire bloodline. Unfortunately, she did not let her go because of the "holy war" that took place thousands of years ago. She was involved in the reverse flow of time and space during the battle. When she woke up, it was thousands of years later and it was already a different era. Where should she go and survive?
