About the Game

《Book of Fei》 is a cute and casual idle RPG played directly on your computer desktop. The game interface appears at the bottom of your system desktop, offering adorable companionship during busy work hours!

Explore Worlds, Battle and Work on Your Desktop

Adventure through different regions in the book world, challenge monsters, defeat the Demon King, and uncover the truth of this realm.

Your heroes battle, level up, and work part-time jobs at the bottom of your desktop.

Interact with heroes to deepen bonds.

6 Characters, 24 Advanced Classes, Hundreds of Equipment & Card Gear

Command heroes to adventure in various regions for leveling up and unlocking advanced classes to become the ultimate warrior. Collect rare card gear with different effects to modify heroes' abilities and build the strongest party.

Assign heroes to work in different areas to earn gold, then purchase and collect superior equipment, combat mechanisms, and enhancement badges to fully boost your team's power!

Collect Badges & Props to Perfect Your Team

Acquire badges and scene props with various effects to optimize your hero squad!

Lightweight Leisure Gaming, Tailored for Office Workers

Specially designed for busy professionals, featuring core functions like screen resizing, interface scaling, one-click interface hiding, and instant game window concealment.

Core Gameplay

  • 6 heroes, 24+ advanced classes, level cap of 2000

  • Battle tiles for auto-farming, work tiles for idle gold earning

  • Hundreds of equipment pieces and cards for team building

  • Decoration system, desktop pet

  • Transparent window design, one-click hide to system tray

Equipment & Badge Enhancement

Equipment can be enhanced to raise its level, with different quality tiers offering different enhancement caps. The badge system provides additional stat bonuses with enhancement up to +100 levels. Soul Badges are a separate advanced badge line with their own progression curve and visual glow effects.

Awakening System

All 6 heroes can Awaken into ultimate classes with new combat mechanics and skills. Each Awakened class plays differently.

Endless Defense

Tower-defense style wave combat. Build-craft with the affix system. Each hero has a dedicated defense talent tree.

Paragon Talents

Endgame progression system unlocked after all heroes are Awakened. Hexagonal talent board with a shared talent point pool.

Artifact System

12 Zodiac constellation artifacts, each with unique combat effects. They drop naturally over time and are displayed in your Artifact Cabinet.

Forge Temple

20+ difficulty tiers of challenge dungeons. Enemies have Demonic Shields that must be shattered. Choose heroes for training, collect materials, and craft Mythical Equipment with random stat affixes.

Auto Challenge

Hands-free stage progression with main-story-only mode, automatic work-for-gold switching, and auto-harvest.

Builds & Synergies

Awakened classes, cards, defense affixes, talents, and artifacts can combine in interesting ways. For example:

  • Awakened Archer with talents and the Sagittarius artifact, multi-shot melting enemies

  • Awakened Priest with passives and Paragon talents to wipe the entire screen

  • Awakened Guardian stacking reflect and shields — the more enemies hit you, the stronger you get

  • Awakened Warrior burning HP with lifesteal, getting deadlier the closer to death

  • Awakened Dancer stacking evasion to 100% for permanent invincibility, grouping enemies and detonating them all at once

Different build paths lead to different combat experiences — worth experimenting with.
