My Street Stall Is a Little Too Impressive

You've just scored the Myriad Worlds Street-Vending System! It offers everything from ancient primordial artifacts to antiques from the Qin and Han dynasties. You can crush spoiled rich brats and charm countless beautiful girls. What takes others ten lifetimes of hard work, I can do with a single System! Wait, this System can also let me transmigrate? I can transmigrate to The Legend of Qin and sell Nie Feng a divine weapon from a xianxia world, then take him on as my disciple. I can transmigrate to the Shrouding the Heavens world and sell a super divine artifact to the Ruthless Emperor... I can transmigrate to the Ultraman world and sell Zero the Thunder God's Hammer... “I want a check! Who can carry a ton of gold?” Zhao Zifeng was at a loss.
