I Woke Up to Find Earth Had Been Turned into a Game

When he woke up, Earth had been turned into a game. Any creature could be a game character controlled by an alien player: a tree by the roadside, a bird in the sky, or a rat in the sewer.

The aliens controlled these characters, evolving and killing as they enjoyed the thrill of the game.

By chance, the protagonist acquired an alien player's game character. From then on, he had two identities. Killing alien players let him level up, and killing Earth's creatures did too. He could cultivate alien techniques and learn Earth's techniques as well.

Alien player: "I want to report this guy. Why can he use Myriad Swords Return to the Sect and the Wave-Treading Steps?"

Earth creature: "This isn't fair! Why can he equip seven or eight pieces of gear? You can't even see his health bar anymore!"
