Zhao Yu arrived on a desolate planet, determined to establish a hidden base. He excavated an underground city, carving out a sanctuary beneath the barren surface. Fearing threats from unknown civilizations, he hollowed out a significant portion of the planet, constructing a star-destroying cannon capable of annihilating worlds, along with tens of thousands of fully intelligent mechanical dogs in various forms. These mechanical dogs served distinct purposes: The defensive model, "Gatekeeper," camouflaged itself as a small mountain, forming a perimeter around the base. The reconnaissance and resource-gathering model, "Skyhowler," disguised itself as a rolling stone, wandering the planet to collect valuable materials. The combat variant, "Nezha," took the form of volcanic craters scattered around the base, poised to strike any approaching adversaries at a moment's notice. One day, a "Skyhowler" unit returned, dragging along a spacecraft and three captured extraterrestrial beings who claimed to be from Earth. Zhao Yu was stunned. Had he not traversed into the depths of the cosmos? How could he be on the far side of the Moon, mistaken by humans as an alien? This narrative weaves science fiction and suspense, delving into themes of identity, solitude, and the boundaries of human perception. Zhao Yu's journey is not only an exploration of the unknown but also a profound reflection on existence itself.
