Capítulo 724: Chapter 724 Guiltless_1

"I'm a bit confused, why could those fires start right under our watch?"

Hearing this, you couldn't help but laugh and say, "Crazy woman, was your middle school chemistry taught by a music teacher? Don't you know that there's something in this world called white phosphorus?"

"White phosphorus?" Xian Qianling frowned.

Sun Mingyu adjusted his glasses and said in an almost mechanical tone, "White phosphorus, a white or pale yellow translucent solid. Soft in texture, brittle when cold, darkens in color when exposed to light. Produces green phosphorus glow and white smoke when exposed to air in the dark. Ignites at about 40°C in humid air and slightly higher in dry air. Under the blazing sun, it can ignite at just over 30 degrees."
