I'm in the World of the Living, and You Say I've Been Working in the Underworld for Ten Years?

[At the invitation of an old classmate, you went to a construction site to perform a ritual. This angered the evil spirits there, and the spirits possessed you, leading you to the rooftop and ultimately falling to your death.]

[After your death, your soul drifted to the underworld, becoming a lonely ghost. Unwilling to resign yourself to your fate, you worked diligently and successfully passed the assessment of the underworld's Yinsi, becoming a glorious ghost official!]

[You worked diligently for ten years in the underworld. Coincidentally, the higher-ups in the underworld wanted to reopen the Yin-Yang Road, and you were chosen and returned to the human world.]

Chen Yang: "No, buddy, are there really ghosts in this world?"
