At 3:17 a.m., I received a food delivery order placed by a dead person.
After I completed the delivery, a new button appeared in my delivery app: [Yin-Yang Exchange: Renminbi ⇄ Underworld Currency, exchange rate 1:1].
After the supernatural resurgence, underworld currency could buy passage, ransom lives, and make the man-eating things stop and negotiate with you.
Others risked their lives trying to satisfy the rules of the supernatural. I paid money.
My sister’s shadow was pawned at a Yin pawnshop. The pawn ticket said: ninety-nine days, ransom one hundred million.
No problem.
In both worlds, everything has a clearly marked price.
