[Let's bring back the classics: zombies, the apocalypse, summoning, a System, waifus from anime, plus Stellaris and an infinite multiverse]
Three years after abruptly transmigrating to a parallel Earth, Li Mo had started fitting into this peaceful world. He thought his transmigration was something special, but nothing had happened in three years. It seemed he had simply moved to an unfamiliar city. So he planned to find a decent job and settle into an ordinary, familiar life. But then the apocalypse arrived, and a virus from beyond the stars swallowed the entire planet in an instant. Endless zombies and monsters appeared. The people who had once helped him either died horribly or became one of the monsters in the blink of an eye. Li Mo was left alone to struggle through the despair of the apocalypse.
