The Heavenly Stone's Debris Walkthrough
Speak with Jinwu
After completing all of Zhiqiong's commissions, return to the campsite and inform Jinwu of all that has happened. Jinwu will then reveal the location of the keys that can be used to unlock the cannonball storage from earlier.
Look for the Two Keys
 Storehouse Security Key 1 |
 Storehouse Security Key 2 |
Head down the the Main Mining area of The Chasm, as shown in the map. Once there, destroy the pot on top of a boiler for the first location, then destroy the wall in the second location to get both Storehouse Security Keys.
Storehouse Security Key No. 1
| How to Get the First Storehouse Security Key | |
|---|---|
| 1 |  Clear the Oozing Concretion with your Lumenstone Adjuvant. |
| 2 |  Destroy the pot on top of the boiler to get the first Storehouse Security Key! |
Storehouse Security Key No. 2
| How to Get the Second Storehouse Security Key | |
|---|---|
| 1 |  Defeat the Treasure Hoarders around the area. |
| 2 |  Head to the corner which you can find by following the footprints to dig up a Geo Barrel. |
| 3 |  Destroy the Geo Barrel to get access to the second Storehouse Security Key. |
Open the Door to the Gunpowder Storehouse
After collecting all the keys head to the locked gate just below the southern Teleport Waypoint in The Chasm: Main Mining Area. Afterwards, use the keys you've obtained to open it.
Once you go inside the storehouse, defeat the Large Geo Slimes, then clear out the Oozing Dark Mud.
Look for the Cannonball
You can find the cannonball on a raised platform near the back of the storehouse, in front of a Common Chest. Afterwards, bring the cannonball back to camp.
Make 3 Special Unmoving Essential Oils
Special Unmoving Essential Oil is crafted using two Cor Lapis and two Frogs. Go to the Crafting Table and find the recipe at the top of the list to start crafting three bottles. Afterwards, hand the Essential Oils over to Clitopho.
Change the Lamp Frequency
Head to the next location and look for the Safe Blasting Device Signaling Guide, which will be on a table in the area. Change all lamps' frequencies to release the safety on the cannon's breach. Here's how to do it:
- Set the frequency of the High Lamp post to Low (delayed flicker)
- Set the frequency of the Middle Lamp Post to Low (delayed flicker)
- Set the frequency of the Low Lamp Post to High (repeated flicker)
Break the Sealing Rocks
Head to the great cannon and align it to destroy the rocks that sealed the tunnel up ahead. Here's how to adjust the Mountainator from its original position:
- Adjust the cannon with the left button once.
- Adjust the cannon with the down button twice.
Afterwards, go further in the newly opened cave. Don't forget to get the Luxurious Chest nearby!
Activate the Mechanism
To activate the mechanism you have to use a Level 2 Lumenstone Adjuvant to activate the mechanisms. You can do this by upgrading it to Jinwu with Lumenstone Ores and Lumenspars. Afterwards, do the following steps on the mechanisms:
- Use the Lumenstone Adjuvant on the purple ooze.
- Recharge each mechanisms to activate it.
- Defeat the Abyss Herald to complete the quest.
