How to get the treasure-digging elements in the original legend?

The acquisition of the attributes of treasure-digging elements requires the use of treasure maps for treasure-digging.

Treasure maps can be obtained by disassembling equipment, monsters falling in the wild, daily activities, shopping malls and so on. If you use the treasure map to dig treasures, you will have the opportunity to get equipment above the dominant level, and you may also get equipment with element attributes.
