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

The sound of a gunshot came from within the school.

Zhao Yu stood on top of the SUV and began to scout around with his binocular.

Zombies were everywhere and no living people could be seen.

"Has the shooting finally started?!"

An hour and a half had passed. Zhao Yu thought they had controlled the situation. Now it seemed that things had gotten even worse.

It wasn't long before more gunshots were heard, spreading throughout every corner of the school.

"Maybe, I won't need to take action myself?!" Zhao Yu thought gleefully.

Just a few minutes later, the gunfire inside the campus gradually died off, leaving only sporadic shots here and there.

This phenomenon meant either there weren't many survivors left or the zombies had been almost completely eliminated.

He lifted his binoculars to double check and saw several buildings outside were now crammed with zombies.
