Liu Lang, who traveled through the Wandering Earth and became the planet's will, originally only wanted to quietly observe this 2,500-year journey.

Unexpectedly, I was drawn into the Civilization Trial game.

.

My name is Liu Lang. I am the behind-the-scenes power holder of the UEG United Government, the master of the artificial intelligence Moss, and the benevolent father of billions of homeless people.

Flowers adorn the branches for the sake of blue skies 2,500 years from now.

We're at war with zombies, aliens, insectoids, behemoths, mutants, and superheroes from another dimension...!

(The theme is interdimensional war between civilizations; the protagonist's existence can be ignored after chapter 15.)
