Turn right and walk over to the hole in the ground...
....and swipe down to grab onto the ledge.
Keep swiping down to continue climbing down the wall.
Move down and tap the gold vase (circled in blue) to obtain a piece of the relic.
Swipe down, to the right, and down to more times to hit the ground. Tap another gold vase to obtain a piece of quartz.
