How to farm

Before you go

Unlock the domain; its listed entrance requirement is Adventure Rank 16.
Plan a run for Wednesday or Saturday, or select Aerosiderite from the Sunday reward choices.
Have Original Resin available to claim the domain reward.

Open the world map and travel to the Statue of the Seven south of Mingyun Village.
Follow the map to Hidden Palace of Lianshan Formula and enter the domain.
On Wednesday or Saturday, choose Trial Grounds of Thunder.
On Sunday, inspect the available reward trials and select Aerosiderite.
Complete the challenge and claim the reward with Original Resin.
At an alchemy bench, combine lower-tier Aerosiderite to craft the higher tier needed for your weapon.
Use the crafted and dropped materials in the weapon’s Ascension menu.

Farming tips

Check the selected reward before starting, especially on Sunday when the domain offers a choice.
Keep lower tiers for crafting; convert only what you need for the next planned ascension.

Repeat, collect and use

The domain can be run again on eligible days whenever you have Resin. Sunday selection is limited to the choices displayed by the domain.

Common mistakes

Running a different trial: verify the reward name before entering.
Expecting Sunday’s schedule to match Wednesday’s: choose Aerosiderite manually from the Sunday menu.
Using all lower-tier pieces elsewhere: reserve enough for the weapon’s next crafting step.

When to stop or switch

Stop when your target weapon’s ascension requirement is met, or switch to another Resin activity if Aerosiderite is unavailable that day.
