As a Ghost Officer, I Just Wanted to Be Promoted

I hold the book of hell as a ghost messenger, and I have the power to seduce the souls and capture the souls. Everyone in the world calls Lord Yama the supreme being of the underworld, but for me, Lord Yama is just a stepping stone. The netherworld is vast and the nine netherworlds are deep. Does my ambition not stop here? I want to break the shackles of the Nine Netherworlds, break the shackles of Yin and Yang, ascend to the realm of the Great Emperor, and rule the Netherworlds of all realms, only then can I fulfill my lifelong wish. Talk in human language below Under the netherworld, beside the underworld, I was originally a cow and a horse, but by chance, I stepped into the gate of the underworld and became a ghost in the underworld. I thought that seducing souls and taking lives was a cold job, and I just had to follow the script and arrest the souls. However, other ghosts and ghosts all follow the process smoothly, I originally wanted to lie down and fish, but when it came to my turn, I was either an evil cultivator or a fierce ghost, either a flying zombie or a painted ghost. The main character was all kinds of difficult people. My superiors and superiors all openly laughed at me, saying that I received a salary like a ghost job, but all I did was the work of a shady general. Later, I gradually realized that only by reaching the highest level step by step can I avoid these trivial things. From then on, King Yama was just the starting point, and Emperor Fengdu was my ultimate goal. A few years later, I was holding the Fengdu seal, and wherever I went, ghosts were crying and wolves were howling. The once arrogant ghost king and ghost fairy could only tremble in front of me. The evil forces that try to disrupt the order of Yin and Yang will eventually be crushed by me. Emperor Fengdu is here. This is a declaration to all ghosts and an insistence on the order of the underworld. All ghosts will surely bow their heads! From now on, I can travel between the Yin and Yang worlds, and all monsters and monsters are under my control.
