Aliens drove their spacecraft to the earth and began to study the earth. The alien world uses three materials to build: biological materials, mineral materials, and mechanical materials. The spacecraft relies on the emitted light to inhale any material, and uses the ship’s furnace to decompose the items into these three materials, which are used to upgrade the spacecraft.

In the process, the aliens caught some women wearing bikinis on the beach and discovered that they could extract the fourth material, purple energy. The aliens began to study these energy sources and gradually discovered their functions.
