There's Something Evil in the Store

When Gou Anbei woke up, the online store he registered inexplicably opened the attribute of all worlds. From then on, goods from all worlds can be transferred to each other through his store. He thought for a while, well, he might as well establish a buyer group and a seller group so that they can inform each other. "What? I can only deliver this product myself?" "Ah? Send it to Lingxiao Palace? Huaguo Mountain? There is also a package in Daleiyin Temple?" "Well, if you don't want to move, we won't deliver the package. They can get it themselves..." Ding! If you successfully deliver a package, you will get a maid! The one with blue hair and black and white maid outfit! "Hel me up!"
