Raising Evil Spirits

Novel Summary
I have calculated for people before I was born, and I have all five yin, and I am born with fierce ghosts. A knowledgeable gentleman said that I will not live to be seven years old. After death, I will cultivate blood-clothed little ghosts to harm people.
In order to save me, my grandmother married me a child-in-law, so that I had an Ann birthday, although I later discovered that the daughter-in-law and sister-in-law are not human…
I have been lingering and panting since I was a child, and I have been accustomed to accepting it, but my grandmother was killed.
For this reason, regardless of karma, I inherited my grandmother’s job of raising ghosts and vowed to send everyone who killed her to hell.
