Treasure Hunt at the Castle is a Side Quest in NieR: Automata.
"You heard from a resident of Pascal's Village of a great treasure hidden in the forest. Go see if there is any truth to the rumors."
"Search for a door in the forest castle that matches the key."
"A rampaging machine has appeared. It looks like there's something ahead."
"The hidden treasure turned out to be storage media containing the forest kingdom's history, made by its machine lifeforms as a show of gratitude to the original Forest King. When you told this to the villager, he recalled a time long ago when he had been shunned by the kingdom's denizens for his strange speech. He was filled with delight that the grave's guardian had been destroyed, and he wished death upon the entire Forest Kingdom."

Treasure Hunt at the Castle Walkthrough
- This quest unlocks after the main quest Report on A2 has been completed.
- To pick it up, go to the gate between Machine Village and Forest Zone and talk to the weird-talking machine.
- Go to the Forest Castle and go forward, then up, drop down a level and continue until you find a chest with a "junk" machine part
- Make to the rightmost room and go up to the highest level you can get, then find a ledge to dash across to grab another junk part.
- Go to where Masamune is and dash across the broken bridge to the right as you exit masamune's shop. Continue going right until you find the last piece
Once you have all 3 parts, your pod will inform you that they can be used as a key. From here, go back up to the level of the Royal Chamber, and go right past the bridge with the Link Type machine. Backtrack until you find the ladder going down, and find two more floors to go down to. Look at your map to identify which floor connects to the outside on the right.
As you find the right floor, you will notice an open window with a tree root you can walk out of towards a gigantic door. A level 48 machine with a tower shield will confront you. After the encounter, approach the King's remains and read his gravestone to obtain an Archives entry.
Return to the Weird-speaking Machine at Machine Village.
- DO NOT defeat the knight guarding the King's body by hacking it before it sees you. This will glitch the encounter and cause the headstone to be unreadable, with the knight fight remaining as a quest maker. since he is a quest encounter entity, he will not respawn unless you revert to a prevous save.
