"Material? Spontaneous combustion?" Gu Qingheng muttered softly.
Yang Ruxin's expression froze for a moment, but instead of defending herself, she nodded, "Yes, after humans or animals die, their bones produce a substance called phosphorus. This substance has a very low ignition point and combusts upon contact with air, emitting a blue-green light..."
"Sister Xin, you know so much." Lin Xiwang's eyes were filled with admiration.
"Your Sister Xin does know a lot. If you want to make something of yourself, you should follow her and learn," Gu Qingheng glanced at Lin Xiwang. "Not everyone gets such an opportunity."
Lin Xiwang nodded vigorously.
Yang Ruxin just looked at Gu Qingheng with a smile. How could she not love a man who trusted her without suspicion?
