The Demon Emperor Goes on a Rampage Across the Stars with a Shovel

[Starts with farming, goes to war in the middle, then returns to farming later]

[Also known as: All the Fluffies in the Galaxy Are Mine]

Shen Yan was the Demon Emperor. After failing her tribulation and being struck dead by lightning, she transmigrated to the interstellar era.

In this era, humans with mental power of Grade B or higher had both human and animal forms.

With no interstellar diploma, no Federation ID, and no detectable mental power, Shen Yan was a person with nothing and could only live on a garbage planet.

But...

Shen Yan looked at the star ring she had found on the garbage planet, puzzled. Why did all the marshals and generals of the Federation and Empire look so much like the little demons she used to raise?

At some point, a mysterious figure began appearing across the various war zones of the Federation and Empire.

This mysterious person loved nothing more than wielding an iron shovel of unknown material to smash countless interstellar beasts to pieces.

She could turn a battle that had been going badly around all by herself!

With this mysterious figure on the field, every battle ended in a great victory.

Before long, people on the Star Network were arguing nonstop over whether she belonged to the Federation or the Empire.

Then the garbage planet stepped forward and claimed her.

[There is a male lead, but he appears very late.]
