Gu Guide

The complete guide to Gu worms — the heart of cultivation

What are Gu?

Gu (蛊) are mystical worms that form the foundation of all cultivation. Each Gu possesses unique abilities and belongs to a specific path and rank. Cultivators collect, refine, equip, and use Gu to enhance their power, survive battles, and ascend through the cultivation ranks.

There are over 2,700 Gu in the bot, ranging from Rank 1 mortal Gu to Rank 9 supreme Gu that control concepts like fate, destiny, and time itself.

Refinement System

Materials

Each recipe requires specific materials and quantities. Materials are gathered through hunting, exploring, and trading.

Essence Cost

Refining costs primeval essence (mortals) or immortal essence (immortals). Higher rank Gu cost more essence to refine.

Success Rate

Each recipe has a base success rate. Higher rank Gu have lower success rates. Failure consumes materials.

Environment

Some Gu require special environments to refine. Immortal Gu (Rank 6+) require an immortal-grade environment.

Co-Refinement

Two cultivators can combine their resources and luck to refine Gu together via /co_refine.

Deduction

Immortals can deduce recipe fragments via /deduce, unlocking new recipes over time.

Feeding

Every Gu requires periodic feeding based on its feed type and feed interval. Feeding is done via the /feed command, which consumes materials from your inventory. If a Gu is not fed, its health drops and it becomes unusable. Immortal Gu have longer feed intervals (120+ hours) while mortal Gu need feeding every 12 hours. The Preservation House Immortal Gu can seal Gu to bypass feeding entirely.

Immortal Gu Exclusivity

Immortal Gu (Rank 6+) are unique — each one can only exist once in the entire bot world. This is enforced through a claim/release system: when you refine or obtain an immortal Gu, a claim is registered globally. If someone else tries to obtain the same immortal Gu, the system prevents duplication. Upon death or transfer, the claim is released. This mirrors the novel's concept where each immortal Gu is a unique existence in the world.

Equipment System

Equipping Gu

Use /equip to equip a Gu for combat. Only equipped Gu can be used in battle or have their abilities activated.

Gu Limit

Cultivators have a maximum number of Gu they can hold, which scales with rank. Manage your collection wisely.

Gu Cap

There is a global cap on the total number of Gu a single cultivator can possess. Excess Gu must be stored or traded.

Preservation

The Preservation House Immortal Gu can seal Gu into a deep sleep, bypassing feeding requirements entirely.
