National Garbage Dump, Picked up Queen Medusa at the Beginning

Xiuyuan traveled to a parallel world. Here, everyone will gain a special ability when they reach adulthood - entering the garbage dump of all realms. As long as you are lucky enough, you can pick up various "treasures". Unrefined elixirs, broken magic books, damaged mechanical creations, and even the remains of ancient powerful men! Xiu Yuan, who was assigned to a barren area, thought his life was hopeless. But accidentally awakened the garbage collection system! Any garbage can be recycled, repaired and upgraded, turning waste into treasure! What's even more outrageous is that the first item picked up turned out to be Queen Medusa, whose body was still warm!
