## Overview

What if you were the strongest being in the world, and your only job was to crush wave after wave of foolish heroes? That's the premise of *Devil King*, a casual idle RPG from developer and publisher 路过的骑士皇. Released on October 27, 2026, this single-player title puts you in the horned boots of the Demon Lord himself, a being so powerful that every challenger falls in an instant. Yet the heroes keep coming, like ants that never learn.

The game runs on two battlefields at once: Defense and Expedition. Both progress automatically, so you can watch your forces hold the line while your expedition party marches out to conquer neighboring kingdoms. It's a hands-off experience at its core, but there's plenty to manage between battles.

## Highlights

- **Dual auto-battle system**: Defense and Expedition run simultaneously, letting you multitask your conquest without pausing the action.
- **Invincible protagonist**: You play as the Demon Lord, who can slay any hero instantly—but numbers can still overwhelm, so strategy matters.
- **Guardians and gear**: Recruit Guardians with unique traits, lead sieges to conquer kingdoms, and collect divine artifacts and equipment to power up your legion.

## Who It's For

If you enjoy idle games that let you progress while you're away, or if you like the power fantasy of being an unbeatable villain, *Devil King* is a solid pick. The dark fantasy theme and tower-defense-like waves of enemies add a layer of tactical thinking, even though the core loop is simple. It's also a good choice for players who want a single-player experience without the pressure of real-time competition.
