There is a dark market in Youzhou, which is not recorded in the human world and does not enter the human world. There is a pawnshop in the city. There is no plaque or couplet, but only a long green lamp with a wick like blood. Pawnshops can be used to pawn everything—gold, silver, love, memories, and even time and life. The shopkeeper has no name or surname, but the world calls him: Suizhu. There is an hourglass in his palm, and the fine sand flows, which can steal the sky and change the day, and can reverse the change of life and death. No one knows that what is locked in the hourglass is not time, but a love that has burned out for hundreds of years.
