Alec shook his head blankly; he only knew that light was everywhere during the day, reaching every corner of the world. Wasn't it supposed to arrive instantaneously? Did it actually have a speed?
"The speed of light is 299,500 kilometers per second, which is enough to circle the continent beneath our feet eight times!" Glenn explained as he cast his gaze toward the Griffin Knights speeding toward them in the distance.

However, Glenn wasn't worried. He quickly cast a third-tier magic—Heat Perception!
The world instantly changed in Glenn's eyes. The darkness around remained, but the incoming Griffin Knights were now strikingly visible, appearing as red dots.
