What the Heck

Ami is a struggling writer so broke she's about to be unable to pay rent or afford food. One day, she wakes up and finds herself in the underworld. After all sorts of twists and turns, she uses the underworld's ultimate invention, the Transmigration Terminal, to travel back and forth between different dynasties, searching for a way to return to her own era... Ahem, actually, the main point is a collection of hilarious incidents during time travel. Yeah, that's it.
