I Caught All the Black Technologies from Other Worlds.

Just like other protagonists, Lin Feng was given a system. This system gives him the ability to grab things from the high-tech world from a 3D sticker. However, other people's are all kinds of black technology, why are mine just toys? You said this is a toy water gun? So what happened to the tank that was blown away? Is this a small schoolbag? Have you ever seen a schoolbag that can turn into a mecha? There's something a little unusual about your toys.
