Either method will work well enough, but we feel digging with ashovel is the fastest method. If you want to use the shovel method to find Empty Bottles, you will need to make the shovel using the resources listed below.

Once you have all of the materials listed above, take them to a builder’s bench, and you will be able to make aRefined Blue Crystal after you get the bottle.

When you have the Refined Blue Crystal made after getting the empty bottle and Blue Crystal, take it back to the ruins. At the ruins, you will need to throw it where you see theblue waterdrop shown below.

Doing so will allow you to complete the puzzle and place thetitan artifacton the altar to the left of the image above.
