[Quick transmigration + Lots of babies + Feel-good story + Not a strong female lead; no fixed couple, and most worlds feature devoted couples]
Michun is a rabbit spirit, just one step away from taking human form, when she is struck down by a lightning tribulation. As she lies at death’s door, she binds to a childbearing System.
