Betrayal is the reason for time travel, and fate is the necessity for meeting. "You help me guard the tomb and wait for the opportunity to come. The person destined to be from another world will take you away from this place..." By chance, a vampire from another world traveled to the hunter world and became a tomb keeper. (Although the heroine is a vampire, her abilities are only speed and strength for the time being. Of course, she will develop new abilities in the future.) The author doesn't like to write lightly for the first time. I welcome everyone's advice. Thank you.
