Swifts, known as footless birds, could fly continuously for ten months without resting—or at least, that was what humans had discovered.
In terms of flight capability, swifts were absolutely in the first tier.
Strong flight capability depended most importantly on the body's structure for flight.

Moreover, cultivation was always accompanied by aberration. Activating a Second Form increased the Aberration Index.
As the number of activated Second Forms increased, the rise in the Aberration Index would become increasingly steep—it was not a linear relationship.
