Description

Only two materials left to find. Time to ask around at the worksite.

Steps

  1. Ask Master Zhang about Wonder Cores
  2. Use Visions to find the Starsplinter Iron
  3. Ask the old man for information about Subrosium
  4. Search for records left behind in the village
  5. Look for Subrosium

Ask Master Zhang about Wonder Cores

Return to where the Jade Chamber is located outside of the The Golden House and speak with Beidou and Yun Jin, then head back into Liyue Harbor and make your way over to the Blacksmith Master Zhang. Here you’ll be trying to gather information on the Wonder Cores, but Master Zhang mentiones that you’ll need to bring him some Subrosium and Starsplinter Iron..

(1 of 2) Speak with Master Zhang in Liyue Harbor

Speak with Master Zhang in Liyue Harbor (left), then go south west of Mt. Tianheng and collect the two pieces of Starsplinter Iron. (right)

Use Visions to find the Starsplinter Iron

After the conversation has come to a close, use the teleport southwest of Mt. Tianheng, then walk behind you a few meters to initiate another scene. Following the scene you’ll need to find two pieces of Starsplinter Iron, so climb up to the top of the nearby rock to find the first piece then look directly ahead to find the second.

Ask the old man for information about Subrosium

From where you collected the last piece of Starsplinter Iron, head over to the village southwest and speak with the villager to see if he has any information on where to find Subrosium.

(1 of 3) Interact with the points of interest around the village until you find the whereabouts of Subrosium

Search for records left behind in the village

Climb up the wall to the left of the villager and interact with the golden marker near the destroyed wooden shack, then enter the abandoned building and interact with another marker near some barrels to discover some backstory on Shenhe’s father. Next up, head up the stairs and enter another broken building to find the final marker which will point you in the right direction of Subrosium.

Look for Subrosium

Return to Shenhe who can be found standing near the villager, then after the conversation walk over to the rock in the center of the lake and forward the time to 17:30 to initiate a short scene. Walk over to the west side of the lake and you’ll see the Subrosium sitting nicely opposite Xiao. Finally, return to the Blacksmith Master Zhang in Liyue Harbor to trigger a scene which will then bring this quest to a close.
