Underground Training Guide

What Is Underground Training?

Underground Training (Dì Xià Lì Liàn, 地下历练) refers to extended dungeon floors beneath surface secret realms — sub-levels accessed through lower entrances in caves and ancient tombs. These zones offer concentrated loot, boss encounters, alchemy ingredients, and story milestones not available on the overworld map.

Patch 0.10.4 significantly improved Underground Training accessibility: visual effect prompts now mark lower-level entrance points, and critical bugs blocking Blood Sea Secret Realm (血海秘境) and Abandoned Spirit Herb Garden (废弃灵药园) entry were fixed. Patch 0.13.14 further rebalanced Blood Sea floor 3 — Shen Zhiyi gifts a Supreme Exorcism Pill on entry, the Blood Shura Bone Demon was nerfed, and the Foundation realm gate was removed so Qi Refining players can pursue the 炼气斩结丹 achievement. Patch 0.13.19 fixed abnormal position softlocks when entering caves, tombs, and secret realms — if you are already stuck, use Shuo Guang Yin (溯光阴) to load the previous story checkpoint after updating. Update to the latest Steam build before following this guide.

Finding Lower-Level Entrances

Underground Training entrances hide within existing secret realm and dungeon structures:

• Cave back walls: After clearing surface floors, look for glowing visual effect markers (added in 0.10.4) near rear passages
• Ancient tomb staircases: Descending stairs or pit entrances below the primary tomb chamber
• Quest-gated access: Some underground zones require main story flags before entrance buttons activate
• Regional maps: Purchase maps from Black Markets and use concealment tokens to reveal hidden paths — see Secret Realms

If an entrance button appears inactive, verify your Steam client updated to 0.10.4+ and confirm you triggered prerequisite quest chains. On patch 0.13.19+, re-enter only after updating — prior builds could softlock position state when transitioning into caves, tombs, or secret realms.

Softlock Recovery (Patch 0.13.19)

If you entered a dungeon on an older build and the game froze or trapped you at an entrance, update to 0.13.19 and use Shuo Guang Yin (溯光阴) to reload the previous story checkpoint — LeiYun's official recovery path. Manual file backup after recovery: Save & Cloud Backup. Details: Patch Notes 0.13.19.

Blood Sea Secret Realm (血海秘境)

Blood Sea Secret Realm is a high-value Underground Training zone associated with late-game demon cultivation content near Luocha Island territory. Pre-0.10.4 builds had a progression bug preventing entry entirely — this is now resolved.

Preparation

• Foundation-to-Core Formation power level with optimized Dantian layout
• Healing pills, Blood Pressure Pills for realm suppression encounters
• Stockpiled action bar consumables for attrition fights
• F8 save before entry — underground boss resets waste in-game months

Rewards include rare techniques, demon cultivation materials, and achievement progress toward exploration categories. Route background (Shanyin vs Wuyin Sea) may affect adjacent quest availability.

Abandoned Spirit Herb Garden (废弃灵药园)

The Abandoned Spirit Herb Garden is an underground farming zone for alchemy ingredients — particularly valuable for Shennong Cauldron players building pill self-sufficiency. Like Blood Sea Secret Realm, entry was blocked by a bug fixed in patch 0.10.4.

• Herb yields: Rare spirit plants not available on the overworld map
• Shennong synergy: Complements cave heaven farming with dungeon-sourced exotic ingredients
• Alchemy recipes: Ingredients feed Foundation Pills, combat elixirs, and resistance buffs — see Alchemy System

General Underground Strategy

• F8 save at every entrance. Underground deaths and failed boss attempts cost travel time and pill stockpiles.
• Complete surface floors first. Lower entrances often unlock only after primary dungeon objectives.
• Align Dantian before entry. No mid-dungeon respec — loaded techniques are fixed for the entire underground clear.
• Budget in-game months. Underground Training runs extend calendar time — plan around Heavenly Foundation age deadlines.
• Check patch notes. Future EA updates may add new underground zones — see Patch Notes 0.13.x.
