My Mother Is a Boss in the Underworld

I am a coffin child who came out of a thousand-year-old evil tomb, and I am also a hidden second generation of "yin". The year I was born, I killed my whole family. In order to survive, I had no choice but to embark on the path of spiritual practice and start a troubled world of my own. What four major families? Break! My mother is as rich as anyone in the world! What is black and white and impermanent? Beat! My mother controls the underworld! What prince zombie? Receive! My mother rules all evil spirits! That's right, my mom is awesome, she can do whatever she wants!
