You Asked Me to Deliver Takeout, So How Did I End Up in a Purple Robe?

[Supernatural] + [Horror] + [Celestial Master] + [Ghost hunting] + [Taoist priest] Before Grandpa died, he told me: “Child, when the blood moon rises and the gates of the underworld open, you must fulfill your duty...” So after graduation, I chose to deliver takeout, braving wind and rain to serve everyone. Then one day, I received a mysterious order, and everything began to change! The blood moon rises, ghosts come knocking, and the Eight Trigrams mark on my wrist opens... I take off my yellow robe and put on a purple one. “Excuse me, is this the takeout you ordered from Are You Dead Yet?”
