There's a Monster Under My Bed

Yun Huangyu worked part-time to pursue her dream of going to college. She worked part-time at night and went to class during the day. However, she did a lot of strange things on her first day at work. In the end, she almost died when she ran home but was dragged under the bed by someone she didn't know. She escaped, but the next day she found a fresh scar on her wrist. The crazy woman next door said: He is back and will give you your blood... He is back, and he is still his "roommate", but the "roommate" is not here to retaliate, but to suck my blood. Is he a corpse friend or a roommate? Yunhuangyu's life was turned upside down from then on. She accidentally broke into a mysterious factory and blew up biological and chemical weapons. She died and traveled back tens of thousands of years, only to find out that her roommate was her ancestor. A faint flower, a phoenix, if we can't be together all our lives, we will be with you even if we die...
