Liu Yu unexpectedly became a member of a magical shop, and before he had time to be happy, he suddenly found that the store was short of energy, and after determining that the store was open at the bottom of the sea and could not ask for help, Liu Yu reluctantly began to save himself. After some tossing, the energy of the store has successfully changed from being able to maintain for more than a year to less than a year, Liu Yu had an epiphany, and if he doesn't change his mentality, he will die. After some hard searching, he finally found the only possible solution to his current predicament...... but there were only 10 [teleportation cards] left, not to mention, there was still a fee, and the only savings could only buy 4, and before he could rejoice, a more serious problem appeared. There is still a limit to store transactions, even if you can only trade ten times a year, the requirements for customers are so harsh. Ordinary sales can at best provide energy for the store and cannot increase its experience points, and unlocking new goods is even more difficult than Liu Yu imagined. Soon Liu Yu found that he didn't look like a serious store manager at all, but a buyer who was active in various dangerous areas. The store was unexpectedly short of everything, and in desperation, he could only incarnate as a top commodity buyer to carry out goods in different worlds.
