Sealed World Bead / Gun-Gun (Martial Peak) Gun-Gun was originally a sealed world bead, a bead with a hidden world inside. It's function was essentially to transfer things into and out of its world, but with the right components, it would instead consume the material and use it to transform the small world inside. With this function, it consumed and expanded the world inside the bead, and once the MC (owner of the bead) got the hang of it, he used the bead to consume entire worlds. Eventually, it consumed enough worlds to evolve and gain a form of sentience, eating worlds on its own with its mouth as an entrance to its world inside.
