The Underworld Is My Home. Come to Me for Dream Visits or Reincarnation

Who would have thought the King of the Underworld was her brother? Her backyard connected to the underworld, and she had no choice but to get to work. Bound to the Treasure House, with a tenfold conversion rate, she grabbed a sack and got ready to haul in the cash~ She sent dreams to visit family, passed messages between the living and the dead, and even had a handsome ghost relentlessly pursuing her. Most absurd of all, she was the reincarnation of a big shot? Did that mean she could throw her weight around in the underworld?
