How to obtain 100 Yellow Everstones?

This part of the game, is a little more complicated, especially without instructions. But basically when this part of the game is unlocked you will see a yellow opening in front of the sandship, this is the Forgotten Underwell, tap to go inside and you will see Four Turrets which cannot be moved or rotated.

Forgotten Underwell

You have to make ammunition in the Forgotten Underwell and deliver it to the turrets. And place objects in the area to help protect the turrets and the other machines that help to create the ammo.

The set you need to make the ammo is Synthesizer > Grabber > Mechanical Assember (with recipe set to Ammuniton) > Grabber > Turrets

Turrets with Ammo

You need to make this setup for all four turrets, and in all of the vacant spaces, put extruders to slow down the enemy bots that are trying to destroy your machines.

It may take some time, but eventually you will get 100 Yellow Everstones.

Things to watch out for is to have enough harvest materials to produce ammo and enough resources that you can still create goods in transit.
