WHERE & HOW TO FARM
Where to farm
Simulacrum Nexus of Mengzhou, reached through Main Quest Chapter IV Act IV: Simulacrum of the Heart.
The Nexus unlock is the gateway to Version 3.7’s region content. Finish the required main story, then use the area map and exploration tracker to work through the newly accessible Heart Realms. Treat this as a one-time progression target: the value is access and first-time exploration rewards, not a recurring material claim.
Complete Main Quest Chapter IV Segue: The Nethermancer’s Requiem to unlock the Act IV quest.
Complete Main Quest Chapter IV Act IV: Simulacrum of the Heart to enter the Nexus.
Have the Nexus map available in the region interface.
Open the quest tracker and select Chapter IV Act IV: Simulacrum of the Heart.
Follow the active quest markers until the story takes you into the Simulacrum Nexus.
After access opens, open the region map and review the seven named Heart Realms: Heartscape Labyrinth, Heart of Flames, Heart of Frost, Heart of Bloom, Heart of Stillness, Heart of Ruin, and Heart of Appearance.
Travel to realms the game has made accessible and activate available fast-travel points as you encounter them.
Use the exploration tracker to identify nearby unfinished objectives; follow its labels rather than assuming every realm has the same puzzle mechanics.
Claim completed region and quest rewards through their displayed prompts.
Check the live Resonator upgrade screen for any material now accessible only in the Nexus, then route toward that specific pickup or activity.
Farming tips
The story gate begins at the preceding Chapter IV Segue; if Act IV is absent, check that quest first.
Three realms have named Key mechanics in the region preview, but the other realms’ mechanics are not established here. Follow in-game prompts instead of expecting every realm to use the same puzzle.
Repeat, collect and use
One-time access and exploration progression. Story quests and completed exploration rewards do not reset as a farming loop.
Common mistakes
Searching for the Nexus before completing the story gate: finish the required Segue and Act IV quest first.
Treating all Heart Realms as equally open at first entry: use the map and tracker to see which areas are available.
Repeating finished exploration objectives for materials: check whether an objective is complete and switch to a repeatable activity when it is.
When to stop or switch
Stop when the Nexus is unlocked, the travel points and objectives you care about are claimed, and the tracker shows no remaining target relevant to your current upgrades.
