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.

Gu Ling responded, "Hmm?"

Gu Ling shook his head, "I would like to hear more."

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?"
