Metropolis: I Have a Wanjie Mall

A mall appeared in Li Cheng's mind where he could trade with aliens from the universe. Can a handful of earth soil be exchanged for money? Can a little flower be exchanged for black technology? Pills that improve physical fitness, wormholes that can travel through space, anti-gravity flying cars, space battleships... Black technologies that far exceed Earth's technology countless times, can all be traded in Wanjie Mall... This novel and its characters are purely fictitious.
