Curiosity killed the cat

Hydrogen sulfide poisoning ...

This diagnosis appeared in Lin Yuan's mind. At the same time, her heart started to tremble. This diagnosis was so terrifying that it could really kill her!

She made a prompt decision and used all her strength to turn around and walk out unsteadily.

Hydrogen sulfide was a colorless gas that was both stimulating and suffocating.

Low concentration contact would only stimulate the respiratory tract and the eyes. High concentration contact would stimulate the whole body, causing symptoms of central nervous system and suffocation.

Hydrogen sulfide had the smell of a stinky egg, but the extremely high concentration of it quickly tired out the sense of smell and made the smell disappear.

Lin Yuan's thoughts spread out, and his solid basic skills allowed some related memory fragments to appear in front of his eyes.
