The eagle slowly spread its wings and flapped them,
seemingly getting familiar with its own body.
Its wings had undergone optical invisibility modification, and now under the sunlight, they were becoming somewhat hard to see, much like a mosquito that disappears in flight.
Originally, the visible light reflectivity of this eagle's feathers was around eighty-five percent, making it easy for creatures on the ground to spot it when soaring on a clear day, especially such a giant creature as the eagle, which could easily be seen by humans in the city.
