Silver Lining

Zhao Yu came to the deserted planet to build a base, create an underground city and hide in it.
Worried about the threat from the unknown civilization, Zhao Yu dug out a small half of the planet and built star destroyer cannons capable of destroying the planet, as well as tens of thousands of fully intelligent mechanical dogs in various forms.
The defensive robotic dog, the Gate God, would disguise itself as a small mountain and fortify around the base.
Detection and gathering robot dog - Tsotan, would disguise as a rolling stone and wander around the planet to collect useful resources.
Combat robot dog - Nezha, would disguise as a crater, scattered around the base, ready to be able to attack the enemies that may come.
Around the base, they were ready to attack the enemies that might come.
On this day, his gathering robot dog - Tsotan, dragged back a spaceship. It captured three alien creatures, claiming to be from Earth.
Zhao Yu was confused. "Didn't I travel to the deep space of the universe? How come I'm on the back of the moon and being treated as an alien by humans?"

People Found Out About The Base I Built On the Moon

On the neighboring planet, the five civilizations were all shocked about the outcome.

However, the detector clearly showed that the five level-3 spaceships had indeed been destroyed.

"Could it be the work of the level-2 civilization?!"

"Impossible, they are still escaping towards the wormhole!"

Kote's fleet was extremely weak, and they had long stopped their counterattack. No one believe it was them.

"What about the native civilization?!"

"This native civilization could not even repel the level-2 civilization, let alone the level 3 …"

People were confused as there are only three civilizations reveal in the solar system.

The native civilization, Kote's fleet, and the last was the level-3 civilization.

Could there be a fourth civilization?!
