I Was a Corporate Drone, Until Grandpa Dragged Me to the Underworld to Work as a Reaper

(Spiritual qi revival + alternate world + urban cultivation + mages + supernatural abilities + shikigami + no System + no heroine + comedy)

I'm a corporate drone who graduated a year ago, but then my grandfather burst out of the underworld and dragged me into becoming a Grim Reaper. The old man even told me that the Ye family is a distinguished clan, with generations of our ancestors serving as judges in the underworld. And now that it's my turn, he says I'm some kind of King of Hell in training. What the hell, is he trying to fool a ghost?
