Lost Precursor City

The Lost Precursor City is a location in the  Crystal Hollows, more specifically the  Precursor Remnants.

Tasks

When the player first enters  Lost Precursor City, they will be greeted with the following message:

NEW AREA DISCOVERED!

 Lost Precursor City

■ Ancient machines protecting ancient cities that hide ancient secrets.

The Sapphire Crystal can be obtained. 6 Automaton Parts are required to claim the crystal, each randomly dropped by killing Automaton or obtained by opening chests in the  Precursor Remnants. Delivering all six parts or a Precursor Apparatus to Professor Robot will unlock the door next to him, allowing access to the Sapphire Crystal.

Right-clicking on the blocks in the door to the Sapphire Crystal will cause them to disappear, although the Crystal will not be claimable unless you give all parts to Professor Robot. The only use it has is to kill the Automatons spawned in the Sapphire Crystal claiming location.
The door to the Sapphire Crystal doesn't reappear, even if the crystal is claimed and placed at the Crystal Nucleus.
There is a room with Melons that can be broken, however they only give Farming XP, no drops or collection.
