Where Once There Was a Calculation Array Walkthrough
Go to Esoteric Arrays in the Ancient Sacred Mountain
After the dialogue with the big Secret Source Servant, move south towards the Esoteric Arrays area. Near the corrupted area, you'll see another servant being attacked by Rifthounds. Defeat the Rifthounds and the servant will start moving.
It will fly to the right side of the area, so glide and follow it.
Clear the Abyssal Corrosion in this Area
The servant will lead you to a door that it'll open. Inside, you'll see more Rifthounds and another corrupted area. Defeat the Rifthounds and the servant will interact with Secret Source Dragon Mech nearby.
Resonate with the Secret Source Dragon Mech
Interact with it and you'll activate the Secret Source Dragon Mech. You'll gain control of the Secret Source Beam Cannon which you must use to destroy the Oozing Cores that appear. Just aim at them and shoot to get rid of them.
Destroy the Oozing Cores
Using the beam cannon, destroy the Oozing Cores that appear until they stop spawning. The dragon will start moving and the door in front will open, where you'll see some Hilichurls, Rifthounds, and more cores.
Take Out the Enemies and Oozing Cores
The Secret Source Beam Cannon will get buffed by lava and now hit multiple targets. Use this to hit multiple Oozing Cores at once or take out groups of enemies during the ride. Keep doing this until you reach the main area of corruption from earlier.
Remove Oozing Cores at Area of Corruption
In the main area of corruption, use the Secret Source Beam Cannon to remove multiple Oozing Cores that appear. Once you're done, the dragon will lie next to the now-purified area.
Interact with the object in the middle to completely purify the area to finish the quest! You'll also get a Phlogiston Unit right after.
