The moon outside the window was bright and spotless, the room only illuminated by the soft glow of fireflies.
Su Liang and Gu Ling sat very close to each other, their breaths detectable.
Su Liang stared at the fireflies, while Gu Ling stared at her eyes brimming with laughter.
"Hey, Great God." Su Liang started, her voice instinctively lowered.
Gu Ling responded, "Hmm?"
"Do you know why fireflies glow?" Su Liang asked.
Gu Ling shook his head, "I would like to hear more."
"Fireflies emit light from their light organs. It begins with the nerve impulse transmitted to the light-emitting cells, which releases the originally suppressed luciferin. There is a phosphorous chemical in the cells of fireflies called luciferin, which, under its own catalyst, oxidizes and the resulting energy is released in the form of light," Su Liang recalled the explanation she saw online in her previous life.
Gu Ling frowned slightly, "Do you think I understand?"
