There are three Ruby Destiny games - please be specific. If you're meaning Ruby Destiny - Reign of Legends, then go to Pina Francia and go down the staircase into the shallow water area. Go into the cave and talk to the hiker guy. He should give you Flash.
In the cave that the ranger is guarding in Rentelbud City. I don't know how to get in there though.
there is no diglett cave in Pokemon ruby only in leaf green and fire red
It's pretty easy. All you need to do is get the HM Flash. If you don't have it, then it will be hard getting through in that cave :)
You must first go through the cave of origin.
Walk to the middle of the cave and use flash.
