Zhao Yu came to the deserted planet to build a base, opened a underground city, and hid in it. Worried about the threat from unknown civilization, Zhao Yu hollowed out half of the planet and built a star destroyer cannon capable of destroying the planet, as well as tens of thousands of fully intelligent mechanical dogs in various forms.
The defensive robot dog - Door God, will disguise itself as a hill and set up defenses around the base. The detection and collection robot dog - Xiaotian, will disguise itself as a rolling stone and wander around the planet to collect useful resources.
The combat robot dog - Nezha, disguised as a volcano crater, is scattered around the base and can attack possible enemies at any time.
Around the base, you can attack possible enemies at any time. On this day, his collecting robot dog, Xiaotian, dragged back a spaceship and captured three alien creatures, claiming to be from the earth.
Zhao Yu was confused. Didn't I travel to the deep space of the universe? How could I be on the back of the moon and still be regarded as an alien by humans?
