Raising Ghosts as Calamity

I was plotted against even before I was born, with all Five Yin present, destined to attract malevolent ghosts. The fortune teller said I wouldn't live past seven, and that after death, I would be raised as a blood-clad ghost to harm others. To save me, my grandmother arranged a child bride for me, allowing me to live a peaceful life, although later I discovered that my sister-in-law wasn't human... Having survived precariously since childhood, I had become accustomed to enduring hardship, but the only thing I couldn't bear was my grandmother's death. Because of this, I disregarded karmic retribution, inherited my grandmother's profession of raising ghosts, and vowed to send all those who harmed her to hell.
