Weird World: I Rely on My Mother and Daughter to Kill My Way Through the World

On the day I traveled through time, I was rescued by a female ghost mother and daughter. He also gave me a golden finger - "The Autopsy Book of the Underworld". After autopsy and channeling, accumulating yin virtue can strengthen all things - exercises, elixirs, weapons, all are strengthened! Water evil? Cut it off with one knife. Pregnancy transfer magic? Uprooted. Paper stick? Burned. Corpse collectors, corpse stitchers, skin painters, wiring masters... I have encountered all the weird trades in this world. Along the way, I solved crimes, killed evil spirits, and strengthened my martial arts. Just three years later, the "coffin" was chopped open and the mother and daughter were taken out. But the deeper the investigation goes, the more strange things point to an ancient force called the "Huangquan Sect". And they have already set their sights on me.
