"Where does the light come from?" Regille exclaimed, this question itself being an age-old conundrum, fundamentally unsolvable.
It was the kind of question that had driven countless philosophers and adventurers to their deaths!
"If I'm not mistaken, within the Flat Kingdom, you cannot find the source of the light," Yu Liang said with a slight smile. It was indisputable.

Logically speaking, light should diminish, so by comparing the brightness in all four directions of the Flat Kingdom, you could determine the direction of the light source and then continuously move towards that direction to find it."
"This..." Sweat drenched Regille's body, for she knew that Mr. Kirito spoke the truth.
This was content recorded in the history textbooks of the Flat Kingdom.
