Currency, destiny, memory, weapons... Chen Xuan recited in his mind.
Currency is easy to understand; it involves using the soul as a solid currency, forged into different quality coins, ingots, or even gems...
Destiny, on the other hand, is Rodiya's choice. Chen Xuan speculated that it was probably the essence of the soul, containing consciousness and the ability to inherit skills.
Then what about memory? What's the difference between the two?
"Destiny has direction, memory doesn't." N77 responded to his question, "You can have multiple memories, human, but you'll only have one destiny."
Chen Xuan was taken aback for a moment.
But he quickly understood. Combining Rodiya's experiences, destiny is akin to a vector with both magnitude and direction. When two people's destinies fuse, a new destiny will be produced, kind of like force analysis, hence the mystical entities claim that destiny has direction.
