After adapting to flying for a while, Carlotta landed on the ground and took out the "Compendium of Card Magic" to read.
She suddenly remembered something about card magic transcendents, that once they reached the Listener rank, they were all capable of mastering a skill known as card battle art.
This was a skill for effectively using cards, and anyone could learn it.
As card magic transcendents' ranks increased, so did the number of cards they possessed. Not everyone had storage cards or spatial items to store cards, and carrying numerous cards on one's person was naturally inconvenient.
Thus, card battle art emerged. This skill allows for the effective use of various cards, achieving an effect similar to storing cards within one's body.
Although Carlotta already had a storage card, she didn't mind learning card battle art. This was a skill every card magic transcendent possessed, and since card magic was her primary focus, she should know it.
